2010 TOYOTA Prius

I started having issue with brakes back in 2018-2019. I brought the car to local Toyota dealer in Pasadena. They suggested that it was not something I should worry about. Just put the car back on Park gear or re-start the car. Their workaround has helped to turn the ABS light off. However I was still hearing weird noise coming from brake.
Then I received a letter from Toyota suggesting that my car has faulty brake booster assembly and will be repaired free of charge by local Toyota dealer. So I went to the dealer with the letter. Unfortunately service rep at the dealer sent me back home without repair. Because they were too busy. He told me to go back if I get the ABS light on again. He also told me that they have not received a notice about this extended warranty. He suggested that repair can be done later unless I want to pay out of pocket.
They refused to look into this issue multiple times due to high number of cars waiting for the service at their facility.

Last week I went back to the dealer. This time they told me that I should have get the repair done back in 2019 when I first went there with Toyota letter. They said that extended warranty expired at the end of 2021. So I have to pay $4K-5K if I want to get it fixed now.

I reported this issue to Toyota Customer Care. Unfortunately they were not helpful. They suggested that this is not their fault as dealer is a private company. Therefore can not provide any help.

Last year on September 13, 2021 I purchase a used 2010 Toyota Prius ( Vehicle VIN JTDKN3DU6A0216154) with 122414 miles on the Odometer, I got my oil changed on October 29,2021 so I can keep track of when my oil is due. My odometer reading on oil change was 123,268. I drove 2806 miles, when I woke up on December 08, 2021 with no oil in my engine. I thought that was very strange so after adding a quart of oil My husband got for me. I took the vehicle back to the shop ( Good Year Tire & Rubber Company 1585- A Island Lane Fleming Island, FL 32003) I originally had my oil changed at, to have them check if there was some sort of leak. The odometer reading at that day/ service was 126,074. After a full inspection of the engine exterior componence, no leak was to be found. Then I decided to do some research only to find out that back in 2016 Toyota had a lawsuit against them for having manufacturer defects in the productions of engine between the years of 2006 – 2011. The manufacturer defect was the engine piston would eventually start having oil leaks into the engine causing engine excessive oil consumption. That same day I took my vehicle to the nearest Toyota dealership ( Coggin Toyota At the Avenues 11340 Philips Hwy Jacksonville FL32256) for a engine oil consumption test to be serviced on my vehicle. This process takes place by filling oil to the full line marking it… confirming there is no leaks….sealing everything and I was to return after driving 1200 miles ( odometer reading at service was 126,094). upon returning the vehicle on December 30, 2021…My vehicle failed the engine oil consumption test because after driving 1221 miles my engine was low on oil by 1.5 quart. This kind of engine oil consumption not only causes my engine to deuterate in time, but also my vehicle diminishes in value. After it was established that my vehicle engine consumes oil / failed the engine oil consumption test. Toyota advised me to get a new engine that would cost me $6987.63 in repairs out of my pocket or to replace the piston in the engine the repair estimate was $5064.05 before taxes and shop supplies. When I asked Toyota about the extended warranty due to oil consumption that was to the replacement of the piston. This extended warranty was issued back in 2016 after there was a big lawsuit against Toyota …. It stated that if a vehicle that failed a oil consumption test, Toyota would cover the repair of changing out the piston in the engine as well as a up to 3 day car rental during repairs and services. This warranty was extended for up to ten years or up to 150000 miles. which ever comes first. My vehicle has less then 130,000 and its not 2026 … but the extended warranty was only issued for some vehicles between 2006-2011. And only the ones that had a 2AZ-FE engine. My vehicle was manufactured with a 2ZR-FE engine. I Have found much research of complaints of people who have my engine a 2ZR-FE with the same engine problems. I saved posts from mechanics that worked at Toyota that mentioned a bulletin was posted on ToyotaNation.com that my type of engine, the 2ZR-FE engine was having engine oil consumption defect. I reached out to the manager ( Michael Adkins) at the dealership of Coggin Toyota at the Avenues11340 Philips Hwy Jacksonville FL32256 to request Toyota to out of good will extend the warranty to cover the repairs on my vehicle but my request was denied. I also requested a print out/ paperwork of the original submission of the goodwill warranty repair request and a copy of the denial response/ letter but Michael Adkins refused to provide me with that information. I then asked him to at least let me know why they refused to cover the repairs…. Michael informed me that they denied my request because I am a new owner of the vehicle and I should go back to the dealership (Gettel Nissan of Sarasota FL) the vehicle was purchased from to request them to cover the cost of repairs. In my mind I was thinking what does me being a new owner of the vehicle or the dealership I purchased it from have anything to do with that fact that Toyota manufactured engines with poor quality parts ( piston) and now my vehicle engine is consuming oil. I have also called and spoken with Blake in management on January 4, 2022 at 1:45 pm (recorded line) and with Jay in management on January 7, 2022 at 5:34pm ( recorded line) at Toyota Corporate office to ask if they can help in any way. All I was asking Toyota to do was take responsibility for there manufacture mistake and fix it. But management informed me that my vehicle was not covered under the extended warranty and there is nothing that can be done. My research has found that just because my engine has a different name 2ZR-FE because it is smaller in size HP ect.. then the 2AZ-FE and sure maybe some aspects of it are a bit different but for the most part both engines where made in the same Shimoyama plant. So I would only assume that some of the parts used to manufacture both of these engines between the years of 2006-2011 may have been used some of the same parts/ kind of parts in manufacturing both engines, Unless Toyota can prove that each engine( the whole engine every tiny piece) was used with completely different parts, and that none of the parts that where used to manufacture the 2AZ-FE engine where also used to manufacture the 2ZR-FE including the piston….. between the years of 2006-2011. It is rather unfair that Toyota would only extend a warranty on one type of engine, the 2AZ-FE engine that was manufactured during the production of the new found oil consumption defect but not issue an extended warranty on any other engines like the 2ZR-FE if the engines are also having an oil consumption defect especially if both engines were manufactured in the same year frame at the same plant. My research has also found that 154 engine complaints have been filed for a 2010 Toyota Prius on carcomplaints.com and 451 engine complaints have been filed for the 2010 Toyota Prius on the NHTSA. I do not know how many more complaints need to be filed before Toyota is finally held responsible for there mistakes. Down below I have attached a number of links and photos that confirm my research. There even is a photo / link that shows some link addresses that have been removed if you try opening them but i guess those links show that the article was related to my vehicle engine type.

Corolla 2010 Oil Consumption – Corolland: the Toyota Corolla Forums

Excessive Oil Consumption with a know design problem. @ 70,000 Mile the engine burns 1+ Quarts of oil every 1000 miles. Dealership refuses to take responsibility.

Excessive oil usage, Current mileage is 77,250.

Excessive oil consumption, 1 – 2 quarts every 1100 – 1300 miles. Toyota Dealer performed oil consumption test two different times more than a year apart. Vehicle failed tests. Toyota claims that the dealer did not inform Toyota the first time the test was done so now that the vehicle has more than 150000 miles they will not repair it.

using too much oil

At 100,000 engine began using excessive amounts of oil, exceeding 1 quart every 1000 miles. Toyota knows this is a problem, and even has a TSB on it — TSB0168-16, and yet refuses to address this issue if past 60,000 miles (most of these problems don\'t even occur until engines reach close to 100,000). Toyota wants 4800.00 to fix.

While driving home on a busy highway this past weekend, suddenly the master warning light comes on, brake warning light, ABS light, SLIP Indicator light, etc. A loud ringing noise begins as well and we lose our hydraulically powered brakes (brake pedal needed to be suppressed very hard to get the car to slow down). As you can imagine, this was a pretty scary moment with no warning given that we had a potential issue. In fact, at our last visit to a Toyota car dealership for regular service, we were told that a master technician said our brakes were in great shape.

After having my car towed to Stevinson Toyota in Aurora CO, I was informed our Brake Actuator needed replaced and would cost $3400.00. They also mentioned I might need to replace a brake pump.

A $3400 repair bill seems more inline with serious engine work, not brakes. I did independent research to see if the dealer was abusing me with this quote. I learned that Toyota paid to fix this SAME EXACT ISSUE on Prius models from 2004-2009, over 600k prius cars in total (warranty enhancement program ZG1). I was extremely displeased to learn that they are covering this replacement on cars up to 10 years old or 150,000 miles. My car is a 2010 with 90k miles and does not qualify.

Low oil indicator would come on very briefly while going around sharp turns. It took several times to observe the symbol because the indicator was so quick to disappear, and finally realized the indicator was for low oil. Added 1 quart of oil. The oil had been changed approx 1500 miles previously. Took car in for a inspection and another oil change. The shop said no leaks, so if it is low on oil again, it is burning/consuming the oil rather than leaking.
1,000 miles after the next oil change the car was over a quart low on oil. Took to the mechanic who also inspected and saw no leaks. Suggested that it has a problem with consuming this much oil and that Toyota had a message out about this problem but did not warranty after 60K miles. Suggested we take it to Toyota to see what they determined.
Toyota looked at the car and said it had an oil consumption problem and that their recommendation would be to replace the small block at a cost over $5,000. The service adviser said that the car was old and that these things happen.
Upon further review we have found that this is very common on 2010 Toyota Prius\' and assert that this a problem Toyota is aware of and should address for their customers.

OIL CONSUMPTION TERRIBLE. NEED TO ADD 1 QT EVERY 1,100 MILES

Multiple headlight failures, at least twice a year since 2012. Usually, only one light fails at a time. This evening, both headlights failed simultaneously in the dark, in the rain. Serious safety issue

MY 2010 TOYOTA PRIUS IS USING A QUART OR MORE OF OIL EVERY 1000 MILES AND I AM BEING TOLD BY THE TOYOTA DEALERSHIP THAT THIS IS NORMAL FOR THESE SARS AFTER THEY REACH 100000 MILES…THIS IS NOT TRUE AND THE PROBLEM SHOULD BE FIXED BY TOYOTA!!!

Oil consumption issues. Bad seals and pistons

My car is burning oil at an exceptionally high rate. I continue to work with the dealership to try and resolve issues, but they now want $3,000 to take my car apart and \'see\' if there is an issue they can warranty. Feeling stuck. Please help!

At 100k my 2010 Prius began burning oil; one quart every 750 miles, sometimes more. I have kept up on all my service dates and I see extensive complaints about this car all over the Internet.

Both low beam headlights do not go on. Were working properly on way to a destination, then did not go on after car was parked after 2 hours. Bulbs are not burned out, fuse is not blown. All other mechanisms on fuse working properly (backup lights, horn). Parking lights and hi-beams work.

My 2010 Toyota Prius, which I bought in September 2016, recently completed an oil consumption failure test (March 2017). It failed, using 3 quarts of oil in 1100 miles. Toyota said they would be willing to pay for half of the $3000 repair cost. However, I was also informed that I would be reimbursed for the remaining cost if Toyota were to issue a bulletin covering this issue. They also gave me a copy of the current bulletin, which covers my car up to 5 years or 60,000 miles. This was issued in November 2016. My car would inherently not have been covered by this anyway, so it sure seems like they are admitting fault without wanting to pay for the repair. I also have service records that show this exact issue happening on 6/22/15 with the previous owner. If this has been happening this long, why hasn\'t Toyota addressed it properly? I have not yet resolved this with Toyota, but I could buy a whole lot of oil for $1500.

I took my car in for routine maintenance and reported that I had been getting alarm beeps when braking for the last month. When I went to pick up my Prius, I was told that the oil was 3 quarts low (!) There has not been any loss in performance of my car so I was really stunned. They are running an \"oil consumption test\" that will show how much oil it is consuming in 1200 miles. The estimate for repair was $2000, though my husband doesn\'t believe that the suggested repair will fix the problem.

My low beam hi intensity headlight bulbs burn out every 6 months or so. The go out one at a time. The original lightbulbs that came with the new car worked a long time. Once they burned out, the new replacement bulbs have not lasted more than about six months.

Excessive use of oil. Dealer said that it was normal for my car to start using oil at 60,000 miles and that as long as I kept a check on it; it would not be a problem. Now I have to put a quart in about every 1,000 miles.

Excessive oil consumption

My Toyota Prius has not been identified as one of the models in this Class Action law suit but at approximately four months ago, at 110,000 miles, my vehicle started to burn oil excessively, causing me to have to fill it every 1,200 miles. I take it in for maintenance to the same person at the same dealership since I have owned the car new. I was notified of this problem with the piston rings with the other Toyota models and that some of the Prius models have also had this issue.
This has me very concerned that other owners have been left out of this suit, considering there are millions of Prius owners that have stood behind Toyota and the Prius as the top hybrid on the market.
I would like something done about this.

Toyota Oil Consumption Defect Class Action Lawsuit is April Lax, et al. v. Toyota Motor Corporation, et al., Case No. 14-cv-01490, in the U.S. District Court for the Northern District of California.

Excessive oil consumption. Toyota is aware and a recall was made for other models but not the prius. The cost of oil makes the fuel economy not worth it. Using over 5 quarts between oil changes is not normal!

My low beam headlights became noticeably more dim dangerously
so as I began to need to use high beams to see anything beyond 30\' in front of me. This began in 2012.
Then my low beam lights began to go out one
side, then the other. We replaced them ourselves with high quality replacements (after we found out it would cost over $200 for
labor and headlamp at our dealer). We were told by the dealer that the problem was only ours they
had \"never heard of it before.\" Over the past three years, we have
replaced 6 headlamps! Today was the 6th replacement and we had it done at the dealers where we were told, again, that this is a problem that they have never heard of before.
Several times, I have had to drive home from work at night in the dark with no low beams (both went out) and use my high beams while cars heading toward me flashed their
lights because of the blinding effect of using highbeams. Please help!!

The car started to burn lot of oil.
Like 1 quart for every 1000 to 1200 miles.
When i googled, i saw i was one in a million as already prius owners were shouting about this issue online.
When i called and explained the problem to autonation dealer in tempe, he clearly understood this problem(because he faced the complaints) and he said it would cost 6000 bucks to fix.
Toyota is not ready to extend the warranty for this problem.
But, the dealer is ready to buy this car for just 1000 bucks.
My car\'s current value in KBB is 7800 bucks.

Toyota should fix this or the dealer shoud talk in a nice manner.

Little yellow triangle with explanation mark in center appeared but no writing on screen what the problem was. Then it came on and said \"key not detected.\" So I changed the key battery. Then I braked on a curve and the yellow triangle came on. No explanation. I then stopped at a stop sign. Yellow triangle with explanation saying \"low engine oil pressure.\" Went to Toyota dealer and they said their was no oil showing on the dip stick. Had oil change done. The dealer recommended driving vehicle and checking oil level every 1000 miles. They also gave me the following #800-331-4331. Since I had to drive moving my daughter I drove 1000 miles in one week. Took car to mechanic today and it is a quart low. He put oil in and now I get to spend $9 every 1000 miles. I called 800# and explained problem. The guy was very nice and after being on hold for 3 minutes he said they are working on a remedy. But he said if it is the engine or drive tran I would be responsible for a fix because I am over the 60,000 miles. He gave me a complaint number and said if they would do a recall I would get an email. But if it is the engine or tran I would pay the bill. What ??? If they caused the problem how would I be responsible. I do have records showing that I took my car in every 10,000 miles for oil change. If anyone reads this and has the same problem please call the 800# and file a complaint. Make sure they give you a complaint number. Thanks

Oil warning system came on. The garage said I had no oil. Service not due for another 1000 miles. No leakage had been noticed. I had them change the oil on April 20, 2016, mileage 95188. Less than 4 months later on Aug. 9, 2016 the oil warning system came on. I watched while the garage attendant added 3 quarts of oil. Mileage was 99712. In 4,524 miles, 3 quarts of oil was consumed, or 1 qt for every 1507 miles.

Over the past three weeks I have noticed the check major system light flickering when turning to the left or right or coming to a sudden stop. I took my car in for the 80,000 mile check and told the service technician what I had seen.

He told me he could tell me what the issue was without looking at the car. He said the car was burning excessive oil, the issue has been reported to Toyota and he would file a case with them for me. He also told me the cost was about $3000 to fix the problem, that I may or may not hear back from Toyota about this.

When they finished servicing my car the technician told me they had added extra oil to top it off.

This is the first Toyota I have owned. I bought it new and have never had an issue with it. I have taken it in for every maintenance check. I was disappointed that Toyota knows about this issue and has done nothing to notify owners of the issue.

MY PRIUS IS A 2010 AND IT IS USING 1QT OF OIL EVERY 1,000 MILE SOMETHING IS WRONG WITH THE RINGS AND PISTONS OTHER USERS ARE HAVING THE SAME PROBLEMS

Excess Engine Oil Consumption. Dealer has asked me to replace the engine at a cost of $13,000.

Excessive oil consumption! As I take very good care of all my vehicles & have regular maintenance performed using synthetic oil, I keep them beyond 200,000 miles. When I had an oil change done in 2015 I was told there was less than 1 quart of oil in the engine, there is no pressure light that comes on when oil is low & I never expected it. After that I did some research online & found many others with the same problem. I go through roughly 1 quart every 1,000 miles. Otherwise I love the car & have close to 200,000 miles on it. If you have a potential solution please call me 480-246-0405 Robert Pierson

Excessive oil consumption, roughly 1 quart every 1,000 miles. I noticed many other people online with same problem & Toyota didnt seem to recognize problem in Prius yet made changes in later years. If anyone can offer some assistance please reach out to me at 480-246-0405 Thank You Robert Pierson

Headlights stop working every 3 months. Sometimes while we are driving. One headlight assembly melted. Toyota won\'t acknowledge the problem.

Design Flaw….loss of brake function during braking events while going over bumps and potholes (lower speeds

Keeps blowing the low beam on passenger side , 6 times in 6 months

When I apply the brakes approaching an intersection, if the road is wet, and if I go over a manhole lid or pavement marking that is more slippery than the road, the breaks release momentarily. On a few cases I have actually gone into the intersection. I notified Toyota about 18 months ago , took it into Burien Toyota in Burien, WA for service (I have a copy of the note I gave them notifying them of the complaint) and they said there was no problem with the brakes. Just a few days ago this temporary failure caused me to run a red light.

LIGHTS KEEP GOING OUT. WE THOUGHT THE BULBS JUST NEEDED REPLACED, BUT AFTER FOUR TIMES OF REPLACING THEM, WE DISCOVERED THAT THERE IS AN ISSUE WITH FAULTY WIRING AND TOYOTA NOW HAS AN ADAPTOR WHICH IS TO RESOLVE THE PROBLEM AND COMES AT A PRICE OF $595 FOR THE BULB AND REPLACEMENT LABOR. HIGH PRICE TO PAY FOR THEIR DEFECT. SAFETY CONCERNS HAVE ARISEN WHEN DRIVING AT NIGHT ON THE INTERSTATE AND BACK ROADS AND THE HEADLIGHTS ARE NOT WORKING.

Brakes needed to stop suddenly at 4 pm on Jan10, on a local street when abrupt stop occurred in front of me, I slammed on brakes and the Prius did not respond . I did not have brakes and my car kept moving forward until I crashed into the stopped car in front of me. My Daugheter and I were in the car. The airbags exploded and we were unable to move the car due to lack of brakes. Fireman moved it and parked until we were towed to a collision center where it is waiting for an adjuster. I am trying to find a Toyota engineer to look at the car to determine why I had no brakes in my emergency situation.Any help you can remit would be appreciated.

While applying the brakes to stop at an intersection one of the front tires was over a manhole cover and the car skidded over it like I was braking on a patch of ice. As soon as I was past the cover the brakes engaged and stopped the car. I noticed this occurring every time I would brake on an uneven surface where there was space between one of the front tires and pavement. I had bought the same make, model and year vehicle for my son 11 months later and noticed the same problem while test driving it. When I questioned the salesman about it I was told that it was the way the ABS works and that it was normal. On 11/20/2014 while checking the airbag recall list I noticed a recall for the same problem that I was having, Recall announced 2/9/2010, NHTSA Ref # 10V03900 so I called Toyota customer service 1-800-331-4331 and was told that neither cars’ VIN# showed in the recall so it could not be happening and I would not be covered under the recall. They referred me to a Toyota dealer who told me that the fix which was (reprogramming of ABS Control Unit Module) would not covered in the extended warranties of either cars. I should not be financially responsible for the diagnostics and repairs of a known safety problem which had a recall. I understand that it is not the dealers’ fault and they shouldn’t be held financially responsible either.

THIS IS THE SECOND TIME BOTH HEAD LIGHTS HAS GONE OUT AT THE SAME TIME.

Navigation controls work 50% of the time and both headlights failed at the same time.

When my husband was driving out of the parking lot in Charlotte on Friday 02/07, all 3 lights – brake, ABS, skid control lights all went up. When he stepped on the brake, he didn’t feel anything. Luckily he was just getting out of the parking lot, so he was driving slowly. When he stepped all the way down on the brake, it had this loud metal rattling noise, and he was able to stop. We towed the car to Town and Country Toyota on Saturday, the assistant service manager said he’s never seen it before, and the error code shown during diagnosis is a code they’ve never seen. The message asked them to contact Toyota technical service. On Monday 02/10, the dealer called and told us that it will cost over $4500 to fix it. We bought the car in Feb 2011 as brand new car, so it’s just 3 years old. I then contacted Toyota customer service, and requested that Toyota covers the repair. I was told that there is no recall program related to this problem, and that if I run into the same situation again, or other people run into the same issue, then Toyota might consider a recall, and would refund me for the repair. This is a very dangerous situation that I hope I’ll never run into it again ever! It just seems Toyota is very cold and indifferent to people’s safety.

Upon braking over a bump, pothole, wet leaves and/or any combination of the aforementioned circumstances, the Prius accelerates forward, thus creating a VERY UNSAFE driving condition. Since I originally purchased the vehicle, it has done this on numerous occasions. I DO NOT feel safe driving this vehicle and am afraid that this braking issue may result in an accident that otherwise would have been a non-issue for any other vehicle. In my 19+ years of driving, I have NEVER had a vehicle do this while braking. I, therefore, implore the NTSB to dutifully carry out its mission statement of protecting motorists by forcing Toyota to recall said vehicle in order to properly remedy this issue before preventable accidents occur and lives are potentially lost.

When braking on rough road, brakes fail, even after recall repair.

Outright break failure while driving but avoided collision. Took to dealer and they indicated the Prius 2010 brake booster had leaked nitrogen into the master cylinder part of the brake assembly ‘contaminating’ it and Toyota recommended replacing the entire assembly (booster and master cylinder) be replace ($1.740 for booster and $2.500 for master cyl). Outside of warranty. Toyota told dealer they would not assist with repairing the defect even though the leak would have been over a period of time to affect the brake booster functionality. I have seen literally thousands of Prius brake failures compiled and consider this issue to be an enormous liability for Toyota that they must address with a recall and a periodic replacement. Always bought Honda but stretched $$s to get Prius 2010 assuming there was a good degree of integrity from this company. This vehicles unannounced brake failure from a defect should ‘ground’ these vehicles until addressed.

i started having breathying problems ,burning skin and eye inflamation that only occured while drivng the carafter constant complaining they found that the fan that keeps the lithium battery cool had clog up and was blowing particles into the cabin of the car.after alot of medical visits they found hogh levels of mercury in my blood.it has cause lung and kidney damage

headlights do not provide enough illumination to drive faster than 40 miles per hour … less than 60 feet on a dark road

A few days ago I found abundant evidence of mice activity in the cabin of my 16 month old Toyota Prius. After some internet research I found out that this is unfortunately an extremely common problem with Prius model cars and other Toyota models. The presence of rodents in the engine area is of course unavodiable but this is the first time I hear about the car design allow mice to easily move into the cabin. This obviously has severe consequences: I already have to replace the air filter and the padding behind the gloves compartment and I am not sure if any other parts have been chewed away. I have to get the car detailed and the air system flushed to avoid toxic contamination from mouse excrements, and more importantly I feel this endangers me every time I drive: a mouse crawling in the cabin of the car while I am driving is a major safety issue! It appears that the placing of screens in as few as 4 parts of the air system would stop the mouse access to the cabin, but Toyota, both my local dealer and the national service center, claim there is nothing the can or will do, and that, despite the abundant evidence to the contrary, this is a normal occurrence in all cars. Many people have posted online about mice and rodents in their Prius cars. A feel this is a major safety issue with the car, and I am extremely disappointed that neither the local dealer nor the Toyota corporate services are willing to help me solve this situation and prevent it from happening again. I think the consequences of this design defect should be covered under the warranty and I hope that Toyota designs a scree part to cover the vents where necessary.

It takes a lot of pressure on the brake to disengage the cruise control. Simply tapping on the brake does not work. The vehicle will be looked at by a Toyota Dealership on 02/16/10. I have owned 44 vehicles and have never had to put so much pressure on a brake pedal to get the cruise control to disengage.

I have over 10,000 miles on the vehicle and have experienced the problem of delayed braking when braking on a bumpy surface. It feels like the brakes disengage momentarily. Also the when disengaging the cruise control with the brake pedal it give the sensation of slightly accelerating for a moment. If you disengage the cruise control by pushing the button on the end of the cruise control arm it disengages properly. I know that they have the software fix for the braking problem but I don’t know if it will fix the one with the cruise control. I think the two are related to the braking problem.

Braking is inconsistent before and after recall fix. Acceleration is inconsistent and car sometimes "lurches" when accelerating from stop.

After purchasing our 2010 Toyota Prius we began experiencing the occasional surge when braking. I filed a complaint with NHTSA and had the Toyota fix performed in Feb 2010. Unfortunately the fix has not solved the issue and my car continues to surge. We decided we wanted to get rid of the car since repeated trips to Toyota did not solve the issue – they deny there is an issue. We tried arbitration and lost since we can’t prove there is a problem. We tried to trade it in and found that we would lose almost 40% on a vehicle that is less than 1 year old. Now we are stuck with a car that we feel is unsafe and we can’t get rid of it. We have continued trying to work with Toyota, but they are unwilling to do anything for us other than look at our car. A quick look at the NHTSA complaint list will show that there are many others still experiencing the brake surge. Thus far we have not had an accident nor have there been any injuries, but we feel it is only a matter of time before someone is hurt by this car.

When slowly backing out of the garage with a foot lightly on the brake pedal, the brakes will successively grab and then release – jerking the car. The jerk is pronounced enough to concern passengers in the car.    Frankly, my initial thought was that I just needed to get used to an idiosyncrasy of the car. However, when another 2010 Prius owner described the same problem at the Toyota dealer customer satisfaction event, I thought enough about the problem to mention it to the dealer representative. He told the group that this was normal for ABS brakes. (It is not normal on our Lincoln ABS brakes.) He also told us that the brakes were basically the same brakes used on much larger Toyota SUV’s. We have not experienced other brake problems, but I am concerned that the problem experienced at very low speeds – in reverse – indicates that the symptom may arise under higher speed situations. (We don’t have icy roads on the California central coast.)

My brake booster master cylinder and pump assembly went out while driving on the freeway. my brakes became soft and unresponsive, though i was able to exit the freeway without incident. my abs light, brake light, and traction control lights all came on. the lights have since remained on and my brakes continue to malfunction. my local repair show diagnoses the issue with the diagnostic trouble code: c1391 back in 2018, before i owned the car, toyota offered an "extended warranty" to have the parts replaced for free for 10 years or 150,000 miles, whichever came first. i'm past the year threshold but well short of the mileage one. i feel a recall should be made and the repair covered, as this is clearly a safety issue.

I was hit in the back by an suv (my speed=40 mph, the suv's speed=70 mph). as a result of the impact, my prius flew off the road, hit the roadside railings, and then rolled over 4 times landing upside down. however, none of the airbags deployed. this includes the front, side, and curtain airbags. the vehicle was serviced at a toyota dealership a few years ago where they performed the airbag recall. however, the airbags did not deploy at all. only sheer luck saved me from death due to the airbag malfunction.

While driving through the mountains, the abs, brake, and slippery (traction control) warning lights all suddenly illuminated on the dashboard. this happened without any noticeable trigger, and the warning lights remained on for the duration of the drive. i'm concerned about potential issues with the braking or stability systems and request a diagnostic check to ensure everything is functioning properly. also i am aware that there was recall on prius 2010 related to abs system. my vin was not included in that but seems like similar issue

Tl* the contact owns a 2010 toyota prius. the contact stated while driving 20 mph and depressing the brake pedal to attempt to stop the vehicle, the vehicle proceeded to roll forward while the pedal was still depressed. the contact stated that the traction control warning light was illuminated. the vehicle was taken to an independent mechanic where it was not diagnosed. the vehicle was not repaired. the manufacturer was informed of the failure and informed the contact that the vehicle was out of warranty. the failure mileage was approximately 209,000.

On tuesday, february 23, our braking system failed on our toyota prius while driving on a side road after months of continuing weakness in the brake pedal and "lurching" when braking over potholes. the brake system lost hydraulic pressure. upon inspection by an ase-certifie mechanic, they determined the brake booster assembly had likely failed, but recommended sending to a toyota dealership. they confirmed the vehicle was unfit to drive. the vehicle was sent to a toyota dealer. the dealer confirmed the break booster assembly/actuator had failed. the dealer advised the brake booster had previously been under a toyota "customer service campaign," but that the "warranty" campaign had expired. however, he advised toyota brand engagement center has often assisted customers when they're just outside the warranty period. when contacting toyota, they stated this vehicle was never under recall and was not eligible, but then said they sent information on a toyota safety campaign. upon research, we continued to confirm that the diagnosis was tied to recall d0h from july 2013. we've also reviewed our vehicle history, and the brake pump assembly was never replaced despite being inspected consistently by toyota dealers since 2013 and under recall. toyota has declined to cover the cost of the replacement for the brake pump assembly. the cost of repair is nearly the same as the current value of the vehicle. toyota brand engagement center has declined to provide this information in writing, would not provide a name, and otherwise acted completely sketchy - for lack of a better word - any time we tried to clarify the repair was clearly tied to the june 2013 recall. we were very, very fortunate the brakes failed on a side street near our home, not on a highway or other high-risk area. we would like toyota to honor the recall, extend it for other customers, and cover the cost of repair.

My 2010 toyota prius has leather seats and the passenger side light is coming on. according to toyota recall there was a problem with the leather seats and calibration.the sensor on the passenger side is not communicating with the front airbag so when you sit down and buckle in it does not activate the front airbag. a seatbelt and airbag light is constantly on.

I inherited a 2010 toyota prius 3rd generation when my mother passed a few years ago. i've since had several unnecessary and costly problems with the car as well as dealership's outlook, treatment, and indifference to the danger that their customers face--as many already have. the following are situations that i'm experiencing now. first, i was recently leaving the pharmacy when all of my warning lights (abs, brake, traction ) suddenly came on and my brakes failed as i was heading home. i'm a single mother of a special needs child and i had to get home to her. i was approximately 1 mile from my home and i was nearly in 3 accidents that could've been catastrophic. thankfully the road was dry, clear, and with little traffic. we have been homebound for weeks, without transportation for doctors, food, etc. our vehicle is our only means of transportation, and we must get to doctor appointments, etc. second, the car has inexplicably stalled twice. third, i'm constantly having to replace lights, and have been pulled over by the police for lights not working. finally, an airbag has been recalled and once i can afford it i'll get that fixed as well. i spoke with my local toyota dealerships, and after explaining the problems, i was informed (several times as i was repeatedly transferred) that i had to pay an inspection fee that also changed with each person. finally, i was told i had to leave my car there for days and that i was going to pay thousands of dollars to fix the car. i'm unable to pay that much money--and the amount kept changing as well. i have researched these problems and now understand the methodology and intimidation used on poor people such as myself. toyota should be ashamed. fix these problems that will endanger and possibly kill your customers for nothing more than their own incompetence and greed.

I was just told that my 2010 prius needs the brake boost assembly (cylinder and boost) at a cost of $2,570. it was causing my 4 month old, 12v battery to drain. i thought that was outrageous so i looked into it and found out there was an "enhanced extended" warranty issued (not a recall) , but for my vehicle it expired april 2020. another issue that i uncovered that this part also causes the prius to lurch forward when braking and you happen to drive over a bump. train tracks, or potholes which is a safety issue. i have also experienced this with my prius. fortunately, i have had no accidents so far. i have read that there have been accidents caused by this issue. toyota should step up and fix the problem before people are injured due to this defective braking system. my daughter drives a 2015 prius. is anything more being done? or are they going to wait until more accidents happen? i stumbled across this issue when my 2010 toyota prius 12v battery required frequent jump starts. i replaced the battery ($300) dec 2020. prior to that, i called aaa and got a jump start. because of covid, i wasn't driving the vehicle daily (work from home) so it was assumed the cause was the vehicle should be driven frequently.

The traction , abs and brake light comes on after driving over a small pothole

Impending failure of the brake booster / brake booster pump assembly. abs and brake warning lights remain on and a constant electrical whining sound can be heard from the brake booster assembly. toyota is aware of the problem and offered a customer support program that expired in 2019 ( https://attachments.priuschat.com/attachment-files/2019/12/178663_162714_zjb_phase_2_.pdf )

While driving at highway speed on interstate 87 in new york, the 2010 toyota prius suddenly lost power while multiple warning lights on the dashboard illuminated, along with a "check hybrid system" notification. the engine would operate but at significantly reduced power. i drove it to an independent garage to identify the diagnostic trouble codes, which included p0a94 and p324e, an inverter problem with the hybrid battery and a problem with the intelligent power module. the currently is currently awaiting a confirm diagnosis at a toyota dealership in new jersey, but the problem is exactly what thousands of other 2010 - 2014 prius owners have reported, yet toyota has yet to issue a recall to replace the inverter.

The contact owns a 2010 toyota prius. the contact stated while driving approximately 30 mph, while coming to a stop on wet pavement, the vehicle failed to stop and crashed into the vehicle ahead of him. the air bags failed to deploy. a police report was filed. there were no injuries sustained. the contact stated that whenever the roads were wet, excessive force on the brake pedal was needed to stop the vehicle. the vehicle was not taken to the dealer and was not diagnosed. the manufacturer was not made aware of the failure. the approximate failure mileage was 208,000.

The contact owns a 2010 toyota prius. the contact stated that while attempting to start the vehicle, the vehicle failed to start up. the contact stated that the hybrid system warning light was illuminated. the vehicle was towed to an unknown dealer where it was diagnosed with the inverter needing to be replaced. the vehicle was not repaired. the contact related the failure to nhtsa campaign number: 18v684000 (hybrid propulsion system) for which the vin was included. the manufacturer was not informed of the failure. the failure mileage was approximately 133,000.

The contact owns a 2010 toyota prius. the contact stated while driving 65 mph, the vehicle lost motive power. the contact stated the check hybrid system warning light was illuminated. the vehicle was not drivable. the vehicle was towed to her residence. the vehicle was pushed to an independent mechanic nearby her residence however, the mechanic was unable to determine the cause of the failure. the vehicle was not diagnosed nor repaired. a dealer was not contacted. the manufacturer was not informed of the failure. the failure mileage was approximately 282,000.

My problem began when i pressed my brakes and instead it accelerated. i thought maybe my foot slipped and didn’t know what it meant. it happened again a few weeks later and then all of the dash lights went on that indicated that i had to have the big brake recall repair. being that my car is past the 10 year warranty and past the extension for mileage, i had to pay out of pocket. this repair was done and upon receiving my car back, the gas mileage instantly began to drop. it went from averaging 42-48mpg in my town to 25-30mpg. i took it in the be looked at and they ensured me nothing was wrong with the car at all. the battery wasn’t holding charge on top of this and it wasn’t reading the same on the dash about the 0-100 current gas mileage you’re getting as you go (the lines scale thing) that goes up when you let off the gas, and i could feel a strange shift while i was driving so i took it in again. they told me this time it’d be $110 to diagnose even though it was the same issue that started after the brake system repair, so i left extremely upset. a few days later my cars steering went out while i was driving and the whole hybrid system died. the car now only works in power mode. the consumer stated the car was taken in for a brake recall and had to pay $2800 in repairs. the consumer stated what they thought was a battery failure turned out to be the beginning of an electrical motor failure related to overheating.

Code 1391. just like many others toyotas of this year

While driving in the highway had several times hard situations. yesterday and truck became in front in my lane while, i had brake fast the car started loosing control and ended up on the side of the road. is like the brakes makes the car loose all the control in a bad situation instead of help to prevent accidents. each time i go to toyota i had mentioned this issue, but they say there's not recalls available. sometimes i think i will die because of this.

The contact owns a 2010 toyota prius. the contact stated that while driving approximately 30 mph, the automatic braking system failed and the brakes were making a strange sound and not responding as soon as the brake pedal was depressed. the abs, brake, and stability control warning lights were illuminated. the vehicle was taken to the dealer and diagnosed with hydraulic brake booster pump failure. the vehicle was not repaired and remained at the dealer. the manufacturer was made aware of the failure but informed the contact that the vehicle was over the extended warranty coverage. the failure mileage was 118,000.

I have a 2010 toyota prius. i was driving home on i-80 and when i was getting down on the slope of the sacramento river bridge, three lights suddenly popped on the dashboard - abs light, brake light and traction control light. following this, i lost efficient control on the brakes and i had to push really hard on the brake pad to even slow the car down. if i had to stop suddenly, it would have definitely resulted in a serious crash. because the brakes stopped working as they are supposed to, i turned on the blinkers, took the exit and tried to stop slowly. i was able to stop on the side of the road just before the red signal. i was just couple of miles from my home so i kept the blinkers on, and slowly drove through internal roads to my home. later when i found out the code, it came as c1391 which is usually for failure of the brake booster assembly or the brake booster pump assembly or both. when i contacted my local toyota dealership, they mentioned that the extended warranty for replacing these parts ended in november 2020 and because of that they asked me to take care of this >$3000 repair. i also contacted toyota corporate to file a complaint and was told the same thing. this issue is a serious safety concern and toyota should issue a recall and not an extended warranty. they should not be waiting for people to loose their lives before they issue a recall.

While driving on an uncrowded 2 lane rural highway at approx. 4pm on june 20th, 2021, i heard what sounded like a gunshot in my ear. i quickly looked around at my interior & saw no broken windows. i had no driving issues, but pulled over safely to inspect the exterior of my vehicle. as soon as i opened my driver's door & exited, i turned to close the door & saw that my sunroof had basically exploded. it was jagged & missing pieces around 3 of 4 edges. i was an hour from home & wanted to make sure i arrived safely. en route i heard chunks falling off & by the time i got home the middle portion had rippled & gaping holes were visible.

Abs light and brake light comes on and goes away on my toyota prius 2010

The brakes failed while driving. the traction, abs and brake light all came on, on the dashboard and the brakes were working at 10% or less. i had to use the engine braking mode to stop the car. i took it to a technician and this is a known issue that toyota is ignoring.

Check hybrid system light ignites, slows down vehicle in middle of high speed highway. first incident november of 2020 then several incidents after. repair shops don't assure problem according to error codes & they recommend possibilities they cannot assure will resolve the problem. car was taken into local dealership after receiving recall notice for software and airbags prior to november 2020 when the issue began. software update took a couple of hours. restart/reboot temporarily allowed driving again. most recently the system entirely shut down & the car will not start or run. abandoned car on side of the road and got heat exhaustion from walking the rest of the way home and had vehicle towed. error lights come on including "check hybrid system" says "shift to p position when starting" and will not allow start.

Actuator and brake cylinder have gone. abs, traction, and brake lights all have gone on. this is a very common issue with this car, and i am expected to pay $3,000 for this fix.

The headlights on my car would get very dim and would burnout within 4 to 6 months. as time has past the time between bulb replacement would get shorter and shorter. at this point when i plug replacement bulbs into my car the burnout instantly. without low beam headlights i am required to drive with my high beams on at all times. the dealer and the manufacture know about the problem and there was a notification regarding this issue with the headlights, but i was not sent this notice. had i been sent the notice from toyota i would have brought my car into the dealership for them to inspect the light problem. from what i have learned from toyota is that there was never a recall on this issue. headlights on a car i would think would be considered a major safety feature and should not have an expiration date on such a repair issue. the program to fix the issue was called customer support program zhb which allowed the dealers to correct the problem. how would anyone know that there was a problem unless they get a notification.

I was driving when the car started to beep constantly. i tried to turn on a road to check it out and realized i had no brakes. i passed the road i was trying to turn on and had to coast to a stop down the road. if this had happened while coming to a red light, there is no way i would have been able to avoid a wreck. i did some research and found that they extended the warranty on the brake booster and assembly pump. the thing is i had taken the car in because the abs, brakes, and traction control lights came on last year. they acted like they had no clue what was wrong and just unplugged the battery and hooked it back up to make sure the lights went off. the lights were off for less than a mile and when i called back they acted clueless and said for $200 out of pocket they can do more extensive testing but said they saw nothing wrong and that the car was driving normally. how does toyota have a major problem that they extend the warranty and the toyota dealership knows nothing about it and can’t give me answers when i have the exact issues the extended warranty is supposed to cover? i could have been seriously injured and hurt someone else and toyota doesn’t care. their representative told me that they had done enough and it was on me to fix the problem as now i was no longer covered under their extended warranty. this is a major safety issue and needs to be a recall before someone gets seriously hurt. toyota knows there is a problem but refuses to hurt their bottom line to protect the consumers. this just happened yesterday and i have not done anything to the car at this time.

While driving on a highway at night around 60 mph, brake light turned on then ab light then slip light. nothing else happened but since this hadn’t happened before, i pulled over, turned off car, waited a bit then turned back on. car still worked although these lights stayed on. continued driving to get home at reduced speed (around 45-50) plus with blinkers on with mental note to take to the dealer next morning. a few miles out, a loud unchanging alarm went off and i couldn’t use my brakes no matter how hard i pressed on them. i was able to glide off an exit that was near and making right turns get into a lot. also neither of the brake pad nor the parking button was working so i couldn’t stop the car but then i hit power to shut down and that was able to stop it. called for towing to dealer the following day. they say it’s the brake booster and that i have to pay out of pocket since it passed a recall but this is a dangerous issue with the car. if the light had been red and a car crossing, without brakes i would have gotten into an accident and since i bought it used last year, i wouldn’t have even known about this being an issue. there shouldn’t be a date limit on this recall, if models of toyota prius needs the recall and it hadn’t been done by previous owner, it needs to be done as this is a really traumatizing and potentially deadly issue.

After buying the car from liquidation station (used car dealer) the day after we bought the (2010 prius hybrid) the breaks went completely out. my daughter and grandchild were in the car and she almost crashed in to on coming traffic putting them in extreme danger of being killed. we had the car towed to caldwell toyota in conway ar. and they said the break booster had failed and that they would not cover the cost of the repairs even though there are several complaints of break failure and several recalls for this car.

The contact owns a 2010 toyota prius. the contact stated that the vehicle was consuming an excessive amount of engine oil. there was no warning light illuminated. the vehicle was taken to the local dealer however, the vehicle was not diagnosed nor repaired. the manufacturer was contacted and informed of the failure. the approximate failure mileage was 220,000.

Brake light, abs light, and traction control light all illuminated on dashboard. took the vehicle to toyota dealership and they determined i needed to replace the brake booster/accumulator and pump assembly, cost was $3,000.00. looking into this issue further it is an extremely common issue and should be a recall item.

All my lights are on traction, brake, abs!

Multiple warning lights came on suddenly when i was driving the prius last month; 'abs', 'brake', and 'traction control' warning lights all came on simultaneously. the braking function was not normal. had to depress the brake pedal a lot more for the brake to be applied. also battery is no longer recharging on applying brakes. took it to the local toyota dealer (fred anderson, raleigh, nc). the estimate for repair is $4045. the car is 2010 model (11 yrs) and has 106000 miles. this is known problem and in my opinion and design flaw and toyota needs to fix this. please help.

My 2010 prius is experiencing brake booster failure. brake assist appears to be lost. feels unsafe to drive since braking distance feels longer. unsure if stability control is working. hybrid battery not recharging from braking. warning lamps include: 1) brake system warning light (red indicator); 2) brake system warning light (yellow indicator); 3) abs warning light; and 4) electronic stability control active warning light. obd-ii trouble code: c1391 (abnormal leak in accumulator). spoke with representative tracy at toyota customer experience center (888-270-9371) on 7/30/2021 (case #210730000924) and randall at toyota customer experience center on 8/3/2021 about repair through toyota. both representatives acknowledged that toyota was aware of the brake booster failure from owners. randall acknowledged that many owners have complained to toyota about brake booster failure and that is it commonly reported to toyota, hence toyota issued a toyota customer support program notification zjb. however, i am told that coverage for my prius under notification zjb has expired, that there is not a recall for the defective parts, and that toyota will not assist with fixing this problem for my car. i believe this problem is a safety issue and that toyota needs to issue a recall as soon as possible to remedy this known defect.

First problem the light on my dashboard appeared. my braking is starting to not work properly. when i press the pedal it feels soft, and the brakes are not bitting well. next thing my abs is not working, that i skid multiple times, and that cause me a few times to almost get into an accident. i had few fender bender issues, but no major damage collision. i end up paying for the repairs of my car, and have the receipt to prove it. also before having all these issues, with the regenerative braking itself, if i happen to hit a pothole, even thou i’m pressing the brake pedals. it causes the car to accelerate. this only happens during traffic stops that i’m already pressing the brakes, but for some reason if i hit a pothole, like i mentioned above. that car accelerates, and thus cause me to almost hit the car in front of me. i was aware of this issue, so to compensate, i pressed the brake pedals harder whenever this incidents happen.

Brake assist has failed. appears to be master cylinder assembly and/or pump? brake related error lights and safety systems disabled. very difficult to drive vehicle without power brakes. car only has 106k miles on it, and too old for enhanced warranty coverage (acknowledged problem). this is not some 20 year old car with 300k miles on it.

Abs brake booster slow leak. there are many reporting the same problem on youtube as a $3000 repair.

Abs pump failed, all the lights came on the dash for brake, and brakes stop working properly it still drives but unsafe to do so, toyota says it’s common problem and they want $3000 to replace it

Code c1391 master cylinder internal leak

Seek exteral brake fluid no external leaks found abs pump noise probable abs pump flalure leak

As many other 2010 prius drivers have experienced, my brake actuator has failed. this has resulted in loss of braking and potential harm.

Parked with car running. car started beeping (beep beep beep) incessantly. turned off. when i turned 2010 prius back on, the beeping came back. brakes did not work. dash error said "check pcs system" and many warning lights were on. pressing brakes didn't stop vehicle.

1. this 2010 prius has a faulty design of the piston rings, which is allowing it to burn more than 1.4 qts of engine oil. 2. such high consumption of engine oil causing an environmental pollution. 3. furthermore, i took it to the local toyota dealer i.e. maguire toyota located in ithaca, ny, they never chose to diagnose it or repair it. 4. i reached out to the toyota and the toyota still isn’t helpful w.r.t this high consumption of engine oil.

Hazards lights came on and would not go off, with increased speed hazards flashed faster. toyota stated that abs actuator and relay needed to be replaced.

The dash lights on my 2010 prius went all dark, lost all information on my dash. no lights on dash, no fuel gauge, no speedometer, nothing. this is very dangerous to suddenly have happened and i don't see a recall from toyota to address this problem.

I have recently bought a 2010 prius. the abs (!) , traction control, and emergency brake light all illuminated three days after i transferred title with the dmv. this apparently is a very common problem with this car. i am told that these lights lead to a very expensive repair. my primary concern is my safety and of course the safety of others. a car that has brakes that suddenly fail is lethal. i was advised by a helpful agent that these repairs would come out of my pocket. my complaint is that toyota should be responsible for this. i cannot drive this vehicle at the moment because i refuse to endanger anyone.

The contact owns a 2010 toyota prius. the contact stated that while driving, the brake lights, abs, and check engine warning lights illuminated. there was an abnormal noise detected. the vehicle was taken to the local dealer and diagnosed that the brake booster assembly needed to be replaced. additionally, the contact was informed that the vehicle was not safe to drive. the manufacturer was notified of the failure and referred the contact to nhtsa. the failure mileage was approximately 115,000. the vin was not available.

The brake booster assembly for nearly all 2010 toyota prius has innate failure over time. it is a faulty, known-issue part. toyota offered some limited-time warranty extension fixes instead of a full recall. my toyota dealership informed my that my part needs the fix, as would be expected, but that i am not within the limited warranty. as this is a safety issue and the part has given out, i am stuck. i contacted toyota directly and via email as well and they refused to do anything while acknowledging the part was their fault. they were very snooty about the fact that a full recall had not happened yet, and gleeful to deny me service.

The digital speedometer display has stopped working. i can no longer see my speed or fuel gauge. i was quoted nearly $3,000 at the dealer to repair the vehicle.

Low pitched rumbling sound from front wheel well when car is moving between 5-25 mph.

The brakes, abs, and traction light came on car but it does not stay on. took it to the dealership and the advisor said it would be $2,500. if this gas been a recall in the past then it should still be a recall. i am extremely disappointed in toyota as a whole to bail out on something that is as crucial as the safety of brake failure.

Last week i check hybrid system message appeared on the screen and orange triangle with check engine light. i took it to the shop and they said that there are code p0a94 wich is related to the inverted and that is needed replacement. i saw that there was recall on inverter and want to see if i can get it replaced. thanks

The contact owns 2010 toyota prius. the contact stated while driving 72 mph, she noticed several unknown warning lights illuminated on the vehicle and a beeping sound coming from the vehicle. the contact noticed that whenever the beeping sound was present, it was very difficult to depress the brake pedal to slow the vehicle. the contact had to depress on the brake pedal all the way to the floor for the vehicle to slow down and for the contact to pull over to the side of the road. the contact waited for a minute before restarting the vehicle and continued to drive a short distance before the failure recurred. the contact was able to restart and slowly drive the vehicle back to the residence. the vehicle was taken to an independent mechanic to be diagnosed. the contact was informed that the abs pump needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure. the failure mileage was approximately 140,000.

While driving traction, abs and brake light came on. braking feels forced by driver.

I have a 2010 toyota prius. the abs pump unit broke down while driving on the road. suddenly the breaks were not functioning correctly. breaks got squeeze. apparently it's a common issue and toyota had a program around it to fix it till jan 2021. but i couldn't go fix it before coz the lights didn't show up. now in oct 2021 it's broken and is not covered. i don't know how a company gets to call such a safety issue as option and not a recall and get away with it. the vehicle has already been identified as having a bad part. how come the company does own up to it considering it's an important part of the breaking system.

We have a 2010 prius purchased march 2010. toyota issued a "customer support program" (free extended warranty) for the brake booster and brakebooster pump assemblies in 2019. the primary coverage was offered until 11-30-19 regardless of milage. after that the secondary coverage applied for 10 years or up to 150,000 miles. the information mailed to us states; "if you have not experienced the condition described above, there is no action necessary at this time." we did not experience any brake problems until 11-10-21, when the dash display lit up with the brake lite, abs lite, slip indicator lite, and the ! lite, all came on at the same time. also the brake peddle became spongy and at times very hard to depress. we had our toyota dealer run a diagnostic scan of the vehicle and they determined the brake booster and brakebooster pump were defected. the car has 70,000 miles on it at this time, and we have owned the car for 10 years and 8 months. toyota will not honor this customer support program since we are 8 months beyond the expiration date. there was a recall number 13v235000 issued 06-05-13 for the same exact problem, with no expiration date. however, toyota says it does not apply to our car. this problem causes the power brakes to not work as power, only manual brakes (hard to push). they also become very soft and not responsive if the engine has not run since the last time the brakes were pushed. this is a dangerous safety issue! ! ! my question is, the problem was a big enough to have toyota issue this 10 year "customer support program" to prevent a hazardous situation from being on the road for 10 years, why is it not hazardous now 8 months later? we welcome any help you can provide.

The airbag light on my 2010 prius intermittently goes on and off. i have brought it to toyota as well as my mechanic to see if anyone can find the problem. i've been told i need to change the seat and or the weight sensor isn't working. when i looked at the numerous prius websites this is unbelievably common!

Brake booster failure; has been inspected and confirmed. warning lamps for traction control, abs, brake system lights, master warning light all came on during normal city driving. immediate loss of brake assist causing sudden need for much more distance while stopping the vehicle. clearly, sudden changes in brake behavior is a safety concern and this problem seems to be well documented as common issue in this era of toyota vehicles. i believe toyota has fallen short in its efforts to remmedy the situation. an extended warranty was issued but it was for a brief period of time that required this problem to occur within a narrow window. it's a wildly expensive repair to a critical system and it seems to be a common problem in these cars.

Recalls.

2010 toyota prius brake booster failure. according to multiple resources online, there have been known issues with this part from toyota across multiple models. after recalling only a small portion of vehicles due to this failure, complaints have been filed with nhtsa to address toyota's lack of corrective action regarding the vast amount of vehicles utilizing this technology. this is a dangerous defect that caused my brakes to malfunction during a cross-country trip. my brake and abs lights suddenly came on, and i could tell my prius handled differently. the brake pedal became hard to depress and stop time increased drastically. i am having a mechanic diagnose and repair this issue costing no less than $1200 in austin, tx. i would like to make a complaint to toyota for not recalling all the models with this issue and instead choosing to recall a minute fraction of potentially defective vehicles.

The contact owns a 2010 toyota prius. the contact stated that while operating the vehicle, the vehicle suddenly stalled without warning. the vehicle was towed to an independent mechanic who diagnosed that the engine had overheated and blown the head gasket. the engine was replaced, and the failure was remedied. the manufacturer and local dealer were notified of the failure. the failure mileage was 164,912,

Last year on september 13, 2021 i purchase a used 2010 toyota prius ( vehicle vin[xxx]) with 122414 miles on the odometer, i got my oil changed on october 29, 2021 so i can keep track of when my oil is due. my odometer reading on oil change was 123,268. i drove 2806 miles, when i woke up on december 08, 2021 with no oil in my engine. i thought that was very strange so after adding a quart of oil my husband got for me. i took the vehicle back to the shop ( good year tire & rubber company 1585- a island lane fleming island, fl 32003) i originally had my oil changed at, to have them check if there was some sort of leak. the odometer reading at that day/ service was 126,074. after a full inspection of the engine exterior componence, no leak was to be found. then i decided to do some research only to find out that back in 2016 toyota had a lawsuit against them for having manufacturer defects in the productions of engine between the years of 2006 - 2011. the manufacturer defect was the engine piston would eventually start having oil leaks into the engine causing engine excessive oil consumption. that same day i took my vehicle to the nearest toyota dealership ( coggin toyota at the avenues 11340 philips hwy jacksonville fl32256) for a engine oil consumption test to be serviced on my vehicle. this process takes place by filling oil to the full line marking it... confirming there is no leaks....sealing everything and i was to return after driving 1200 miles ( odometer reading at service was 126,094). upon returning the vehicle on december 30, 2021...my vehicle failed the engine oil consumption test because after driving 1221 miles my engine was low on oil by 1.5 quart. this kind of engine oil consumption not only causes my engine to deuterate in time, but also my vehicle diminishes in value. after it was established that my vehicle engine consumes oil / failed the engine oil consumption test. toyota advised me to get a new engine that would cost me $6987.63 information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

The brake assembly is noisy while stopped at lights. the brake pedal continues slowly downward when pressed as if there is a leak in the brake master cylinder. toyota has issued a warranty extension for a problem of fluid leaking in the brake booster, but did not notify me. toyota's code for the warranty extension is customer support program zjb. two local dealerships have refused to perform the repair because the warranty extension expired before i became aware of the issue.

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed, the abs, traction control, and parking brake warning lights illuminated. additionally, the brake pedal was difficult to depress. the vehicle was taken to the dealer and diagnosed with brake booster pump assembly failure. the brake booster pump assembly needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure but informed the contact that there was no recall associated with the vin. the contact related the failure to nhtsa campaign number: 13v235000 (service brakes) however, the vin was not included in the recall. the failure mileage was approximately 88,500.

The contact owns a 2010 toyota prius. the contact stated that the braking system warning light was illuminated. the vehicle was taken to the dealer and diagnosed with a brake fluid leak in the brake master cylinder. the vehicle was not repaired and remained at the dealer. the manufacturer was made aware of the failure and informed the contact that the extended warranty had expired. the failure mileage was approximately 81,000.

While driving, my traction lights, abs light, and brake light came on the dash with no noises or other messages. i noticed my brakes took significantly more distance to stop and then stopped working altogether. i had to use my emergency brake to get stopped safely.

2010 toyota prius. consumer writes in regrds to defective abs system. the consumer stated the dealer advised the brake accumulator. the consumer was informed about a recall but, it had been discontinued. the brake booster pump assembly was replaced at the owner's expense.

My prius appears to have the same problem that an excessive number of other 2010 priuses have with it's regenerative braking. this is a common and well known issue among these cars. despite the fact that i am at 132k miles, under the 150k limit for the extended warranty, i am going to be stuck spending thousands and thousands of dollars to get my vehicle fixed because it is about 2 years past the 10 year limit.

The brake booster and master cylinder failed causing the braking system to fail while driving

The contact owns a 2010 toyota prius. the contact stated while exiting the highway and getting into the right lane at 60 mph, the abs warning light, brake light, and the traction control warning light illuminated and the vehicle lost braking functionality. the contact depressed the brake pedal with added force to get the vehicle to slow enough that he was able to get off of the highway ramp and pull over. the contact turned off and restarted the vehicle; however, the warning lights were still illuminated. the contact stated that extra force was needed to stop the vehicle. the contact drove the vehicle to his residence. the contact has not taken the vehicle to a local dealer. the vehicle was not repaired. the manufacturer had been informed of the failure. the failure mileage was approximately 182,000.

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed, the vehicle started making a beeping noise. the contact stated that an unknown warning light was illuminated. the contact pulled into an apartment complex and while depressing the brake pedal the failed to respond. after driving over several speed bumps and using extra energy to depress the brake pedal the vehicle responded and slowed to a stop. the vehicle was towed to the dealer where it remained. the contact stated the dealer informed her that the brake master cylinder and brake booster pump needed to be replaced. after researching the cause of the failure, the contact referenced nhtsa campaign number: 13v235000 (service brakes) however, the vin was not included. the manufacturer was contacted and informed of the failure. the contact was then informed that the vehicle warranty had expired. the approximate failure mileage was 180,000.

Brake warning lights, traction control, and abs warning lights all illuminated on the dash. taken to the dealership and was told brake failure due to actuator or brake boost. upon further research, it looks like this is a known issue with the prius but toyota is only providing service/repair to certain vehicles who already show brake failure instead of issuing a recall for all potentially affected vehicles.

In nov 2020 i was informed that my abs actuator needed to be replaced since all warning systems went off and brakes were disabled. on march 13, 2022 the abs and traction system warning came on again . on march 14, 2022 i had my car towed to daves ultimate automotive in austin, texas because my brakes failed. they told me i needed to replace the brake booster which is going to coat me $2500. i have looked at car complaints and this seems to be a faulty system that toyota is aware of because they extended a warranty to dec 2019. it is my belief that this should be a recall because of the dangerous potential of no brakes when this system fails.

Brake system fails under normal driving conditions. dealership diagnostics confirmed this falls under the customer support program zjb. this program expired in 2020 and toyota customer care is unwilling to fix or reimburse for the $2200 expense associated with the defective brake booster and brake booster pump assembly. the toyota case number is #220318001387.

For the past 2 weeks my prius has been acting very strange. when driving i have a hard time coming to a stop when pushing the brake and i realize that that the abs light is on as well the brake light is on. sometimes it will work fine with the lights off, and somtimes it messes up again. i heard that it could be a brake booster or module. i believe it was already recalled a few years ago, but seeing a lot more people complain about recently is a bit concerning. the part that was replaced, it should work for many years not less than 10. its a huge risk for myself and others. i didn't realize what was happening until i needed to stop fast. this needs to be fixed fast and the right way this time before somebody dies

2010 prius brake, abs, traction control lights on/off with no codes i bought new car and running smooth so far. i got this lights 2 months back and off for sometime and came back on and off and now quite often coming back and forth, 106k miles had the abs, traction control and brake light all come on at once same time and off same time and back and forth. no codes and no flashing but this is very critical as all related to brake systems failures may leads to crash because we don't know when this lights on and off and no codes to fix this issue.

Traveling at freeway speed just after midnight, the "check engine" light came on. less than one minute later, the "check hybrid system" alert came on, with an exclamation mark inside of a yellow triangle symbol displayed. the vehicle instantly had no power when the accelerator was depressed. the vehicle coasted to a stop and would not shift into drive. the vehicle was towed to our home. upon delivering the vehicle to our home, the tow driver used an emergency battery jump start device and the vehicle was able to shift into drive and be driven into the garage. the 12 volt battery was replaced the next day and the vehicle no longer exhibited any disfunction. this was an unexpected event with no warning that the 12 volt battery was in need of replacement. it could have resulted in a serious collision, if the freeway had been more congested, as the vehicle had been immediately driven 2 lanes over to the nearest exit, and came to a stop just after exiting, safely at the side of the road. this is a very dangerous safety condition that should have had some type of alert that the simple 12 volt battery system was in danger of failing, causing a catastrophic failure of the engine and power train. or, the car should simply not be able to drive, if the 12 volt battery is that low, to ensure passenger and community safety. prime example: toyota prius has a warning alert that the key fob battery is low. the warning gives you a couple of weeks to replace the battery, and repeatedly displays the warning whenever you power up the vehicle.

A number of things have failed on this car. 1. the hybrid battery pack system shut down and warned that i needed to see a mechanic. my mechanic diagnosed that the hybrid invert was defective and causing the battery pack to fail. 2. when braking at both low and high speeds, the car increasingly struggles to come to a stop. when applying foot pressure, you can hear the pump winding - this occurs while at rest as well as when trying to slow the car down. there are times when applying the brake that the floor pedal will lock and cause the car to skid while barely reducing the speed of the car. i have had multiple near accident incidences as a result and put myself and others at risk. 3. the car ferociously vibrates every morning - discovered that the head gasket has failed prematurely and due to the car overcompensating for the failing hybrid battery that is being impacted by the failing hybrid inverter. all problems have been reproduced and diagnosed at independent service centers. multiple codes, warning lights and messages have alerted me to engine and battery issues - all of which appeared after the various issues and failures.

As nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. under certain circumstances, this condition could affect stopping distance and increase the risk of a crash.

I was driving on the road and right before a stop light my car jumped as if someone hit me from behind. after looking in my rear view and seeing no one on me i realized something else happened. i look at my dash and check hybrid system light was on. i was in traffic at the light waiting and looked it up on my phone to find out what to do. some article said to pull over and turn it off and restart it. the light turned green and traffic started moving so i started to drive. i thought i could probably make it home but the car started driving a lot slower than usual. i really didn’t want to pull over because it was in a bad part of town but i felt like i had no choice because the car was barely moving. it seemed more dangerous to be on the road with other drivers. so i pulled over and parked and tried starting it again. it wouldn’t shift to drive so now i’m stuck and can’t get home unless i pay to get my car towed. i get my car towed to the house. i put a meter on the battery and it was fine. i put a diagnostics tester on it and came up with these codes poa1a and poa94. i contacted hybrid mechanic that doesn’t work at toyota and he said to take it in to a dealership and sent me the ze3 warranty letter and said they would fix it. i paid for it to be towed to the dealership. there were already a lot of cars waiting to be serviced when i got there. anyway, they said they would fix it after they did their diagnostics after i paid $120 for it. that was 3/21/2022. i sent csr the ze3 letter and he said it wasn’t covered. it’s like he didn’t even read it. a day later he said he needed to talk to a warranty administrator then a day later he said it would be covered but i don’t qualify for a loaner but they can give me a rental for $45 a day. i friend let me borrow their car for a couple days. now as of writing this it’s midnight 3/30/2022. i still don’t have my car and i’m about to be without a car unless i buy one or rent one. no eta on the part being delivered either. i’m sol.

On march 25, 2022, i was driving my 2010 toyota prius, approx. 209,000 miles. when i had parked my vehicle, and turned my a/c on, my vehicle started to make this annoying beeping noise non-stop and all of the light on the dashboard had lit up. my brake lights, abs, and the slip indicator all came on. when i went to drive my vehicle all of sudden my brakes did not respond. i had to force break and push down on the brakes very hard, to the point where i'm flooring the brakes. i checked with toyota to see if there was a recall on my vehicle, and they told me that there were no recalls. when i did my research on 2010 toyota prius, i found that this is a common issue that the brake actuator and brake booster pumps are faulty on these vehicles. i did not receive a recall notice for this vehicle. currently, my vehicle is not drivable and not safe to drive. for this to happen out of nowhere with no warning is unacceptable.

I drive a 2010 toyota prius. color of the car is pearl white and its starting to peel off and bare metal of the car is getting exposed. exposed metal will start rusting and start impacting the sturdiness of the car and eventually the safety. toyota manufacturer already has a recall in place for several toyota models for same pearl white paint as shown in link below but prius model is not part of it. i feel prius model should also be included in this recall plan as it uses same pearl white paint. its a manufacturers defect and they should fix it at their expense. https://www.cbc.ca/news/canada/nova-scotia/defects-autos-paint-toyota-warranty-extension-1.5459368

My brakes have been making hissing noises whenever i press on the brake pedal for the past year. while driving on the freeway 300 miles from my home, numerous lights on my dashboard came on including brake, vsc, pcs, abs, triangle and "check pcs system" warning message. the brake also makes pumping noise every 4 seconds. the vehicle has no regenerative braking. the brake pedal is mushy and doesn't slow the car down until the pedal is fully depressed. i contacted toyota and was told that there was a customer support program zjb that covers 2010-2015 prius vehicles for brake booster and brake booster pump assemblies. however, that program only covers 10 yrs 150 miles. my prius has 110k miles but it's 21 months passed the program coverage. the car is dangerous to drive and toyota will not honor the recall. i am stuck with a car with no brakes.

The contact owns a 2010 toyota prius. the contact stated while driving at various speeds, the brake pedal was depressed however, the vehicle failed to respond as needed; causing the stopping distance to be extended. the contact stated that the abs, brakes, and traction control warning lights were illuminated. the vehicle was taken to an independent mechanic to be diagnosed. the contact was informed that the abs system and brake booster needed to be replaced. the local dealer was contacted and the contact was informed that nhtsa campaign number: 10v039000 (service brakes, air) had expired. the manufacturer was notified of the failure but provided no assistance. the approximate failure mileage was 220,000.

Hazard lights flashing, flashes faster at higher speeds. hazard button useless. mechanic not sure what is the problem; reset codes. problem went away for a few days and then came back.

My toyota prius has significant problems with mice entering and living in the vehicle. they stay in the cabin filter area and there is evidence they come into the cabin and deposit feces on the floor mats, glove compartment and air filters. there are numerous instances of this on online forums and it appears toyota does not design to deter rodents. vent openings are large and unscreened and there are numerous areas in the car that are perfect for mice and rodents to live. other cars do not have this issue. toyota must design their cars better so as not to be infested with mice. they must screen openings to vents and other access points and limit areas that are appealing to mice and rodents to live. this is a health and safety hazard. recently a mice died somewhere in the dash area behind the glove compartment and it has created a horrible smell. i do not leave food in my car and keep it very neat and clean. this is clearly a design issue and many people have reported this on prius and toyota forums. thank you for taking this concern seriously. it has cost me a lot of money and been very difficult.

The traction control, abs, and brake light all came on simultaneously. it was random with no trigger. the brakes feel spongy, and will not regenerate to charge the hybrid system.

Hi- i have a toyota prius 2010 model and i encountered a braking failure yesterday. my abs lights, brake lights and another light came up on my dashboard of the car. upon diagnosis, i was informed by toyota dealership that my car has a faulty c1391 - abnormal leak in accumulator. this condition may be caused by small internal brake fluid leak inside the brake booster assembly with master cylinder. this is a known issue by toyota and lots of press coverage on this issue since the past few years. i was told today that if this issue occurred within 10 year or purchase or <150k then the repair work would be covered by toyota. i purchased the car in 2010 and i past the 10 year mark but mileage coverage is 125k (<150k). toyota is unwilling to bear the cost and would want me to pay for the fix. this is a known issue with toyota and the braking system can fail anytime before/or after 10 year mark. it is now costing me $3000 to repair. i am shocked with the toyota's response in this matter. there are lots of blogs i read online who have similar issue. class action lawsuit: https://www.classaction.org/news/toyota-hit-with-class-action-over-alleged-refusal-to-fix-braking-system-defect-in-hybrid-vehicles here is one example: https://www.youtube.com/watch?v=xa9jyrbzdwo thanks.

Brake booster/ brake pump / accumulator sudden failure believed to be caused by the sensor warning system ? that abs light assoociated with constant beeping noise, 10 seconds later lose of brake power. factory trick to get brake service, at large for this repair costs 3800 per dealership toyota carlsbads. manipulative recall disallowed me on 3 occasions unable to get part replaced by toyota. when contacting corporate the did not demand me to get fixed and not drive ny car, again getting my car to tge service station experienced noise occurring then sudden outage of brake power reduced to nothing. a similar youtube video and my personal video explain sudden loss of brake power or pressure... after lights go on. and immediately return to normal after lights get reset. sensor failure leading to brake failure, really scary and obviously a big problem toyot should still be responsible for. consumer service program by toyota for this brale booster issue stopped for some reason in 2019 also. 150k bs rule. mercedes benz has taken the right action to fixing brake booster issues.

There is a known problem with 2010-2015 toyota prius brake actuator assembly and also the brake booster pump assembly. a leak develops and cannot hold proper brake pressure which will lead to catastrophic failure of the system and a life or death brake failure. toyota has acknowledged the problem and issued a recall only covering 150,000 miles or 10 years from date of first use. this recall should be extended to all affected vehicles for the lifetime of the vehicle given that it is a known manufacturing defect affecting life and limb and that repair costs average over $3000.

Abs brake light on. just purchased this vehicle and found toyota knows of a defect in the master brake cylinder that causes it to leak. toyota was repairing this problem free of charge till 2019. this vehicle has never had the repair. i am told brakes may go from power brakes to non power brakes while driving. we are not driving till it gets fixed because of safety problem with brakes.

Normal braking pressure failed to stop the vehicle requiring the driver to apply very heavy pressure to stop the vehicle and avoid a rear end collision. multiple dash lights appeared and the vehicle was towed to a toyota dealer. the dealer confirmed codes c1252 and c1256 exist and recommended that the brake booster pump assembly be replaced. an august 6, 2018 toyota service bulletin (t-sb-0079-18) recognized this problem. toyota sent customer support program notification zjb noting that "toyota has received reports about certain internal malfunctions of brake booster assemblies in some of the subject vehicles. in these reports, customers have noted various brake system related warning lamps illuminated." toyota noted that, "this is not a recall." toyota suggests that certain warning lights may illuminate but does not warn drivers that normal braking may cease and that the vehicle can be dangerously difficult to stop.

A known defect was briefly recalled, then sunsetted. my brake attenuator has failed, as has been the case for many others on this model. toyota has acknowledged the defect, but no longer supports it.

I believe brake actuator seems to be malfunctioning. noises come from the location of the brake actuator when i am lightly braking at low speeds. i am getting antilock braking system code "c1256" reading "accumulator low pressure". there are a similar recalls related to my issue. recall number: 10v039000 and recall number: 13v235000

Brake booster/ brake actuator problems

Strut mount on monroe quick strut catastrophically failed with no warning. no corrosion noted, appears to be metal fatigue due to inferior design / manufacturing of aftermarket strut mount. failure happened when leaving driveway at low speed; no prior noises or warning occurred.

I purchased my car in january 2010 within that first year i noticed that randomly if i hit a bump in the road and i would apply my brakes my car would do a wired skid and i couldn’t break properly. this has continued the entire time i’ve owned my car. last month i was driving down the highway and abs! red brake light and abs warning light all illuminated. as i was exiting the highway and applying the break i noticed my brakes were very spongy taking considerably more effort to stop. i started noticing a few months ago my breaks took considerably more effort stop and breaks felt spongier. the day my warning lights lit up a mechanic stated a code of c1391 was detected. indicating break booster problems. nhtsa issued a recall rep 13v235000 which is break booster my car was manufactured 10/09 so i understood my car was part of this recall but toyota claims that is not a recall but a customer support program which has expired 2 years ago. i’m the original owner w/ 69,000 miles. clearly my vehicle has and continues to have break issues so why is toyota shirking responsibility and endangering me and other drivers allowing a car w/ breaking issues to not be properly repaired under the recall

Brake booster failed. brake actuator failed. abs,brake and traction control light is on.

The car while being driven experienced a hard unprovoked break while on the road. the check hybrid system light then went on. the inverter has gone bad despite me completing the previous recall repair meant to avoid this issue. toyota in 2021 agreed to pay for failed inverters outside of warranty on some 2010 priuses but my vin is not included in that recall. the repair cost nearly meets the value of the car at this point and also almost caused an accident.

The contact owns a 2010 toyota prius. the contact stated while driver was driving 65 mph and depressing the brake pedal, multiple times, the vehicle brakes failed to stop the vehicle within a reasonable time. the contact stated there were several unknown warning lights illuminated simultaneously. the driver was able to slow the vehicle using the parking brake and driving onto the grass on the side of the road. the driver was able to continue driving to the local dealer. the vehicle was diagnosed and the contact was informed that the braking system needed to be replaced. the vehicle was not repaired. upon investigation, the contact associated the failure with nhtsa campaign number: 13v235000 (service brakes) however, the vin was not included. the manufacturer had been informed of the failure. the failure mileage was 179,747.

The brakes abs stopped working. it is a known issue and is effecting many older prius drivers.

The contact owns a 2010 toyota prius. the contact stated while driving approximately 25 mph, the abs warning light illuminated. the contact stated that the braking system was not normal however, the vehicle was drivable. the contact drove the vehicle to an independent mechanic who provided the contact with a code for an abs fault. the vehicle was not repaired. the contact notified the manufacturer of the failure. the approximate failure mileage was 136,000.

The abs, brake, and traction control light came on. the braking became difficult. the car did stop but if it was in an emergency circumstance there may have been a collision. i called toyota about the issue and was informed that there was a brake actuater and master cylinder issues with this make and model. toyota replaced them in cars that had this issue under a special warranty that was over in 2021. it is a $3500 issue. i purchased this car new and have never received a notice about bad braking system. i have lived at the same address since the purchase. toyota informed me that notices were not sent out, however if the owner came in with this issue before 2021 it would have been repaired and replaced. i can not understand how all owners were not informed. i do not understand how a recall wasn't enforced. i live in florida where the speed limit is 70mph. this could have been deadly. i looked on forums online and apparently this has been an issue for many many 2010 toyota prius. i have a case in with toyota american. 220701001489. i can use any help i can get with this issue. it may save a life.

The braking system malfunctioned resulting in loss of braking ability and response along with various warning lights including abs, brake, and traction control. the vehicle produced a c1391 diagnostic trouble code (dtc) indicating "abnormal leak of accumulator pressure." after taking the vehicle to a local toyota dealer, i discovered there was a voluntary customer support program to replace what was known to be defective brake booster parts that expired in 2020. i previously did not receive any notification about the issue and am now told it will cost thousands of dollars to replace the brake booster parts known to be defective. i now have a vehicle that is unsafe to drive unless i spend an exorbitant amount of money to replace the aforementioned parts.

2010 toyota prius. driven about 10000 miles a year. brake booster system went out at about the 125,000 mile mark. reason to complain is no parts are available for repair and it is a common problem. check out youtube.com about it. dealer has a long waiting list, with no idea of availability. local repair shops do not have any pumps, meaning there are many cars being driven with defective brake systems. an unusual toyota recall for the brake problem happened in 2019 that expired in 2020 but my brakes were ok at that time. with so many prius vehicles on the road, this problem needs more exam and toyota forced to provide quicker relief, even a recall.

When start the car, passenger side airbag light stays on until shut-off the engine.

While driving, without stepping on the brakes, a number of warning lights came on; including brakes, abs warning, and stability control. when attempting to stop the car the brake pedal went down a long way before the brakes engaged. i then limped home. after deciding what to do i called a toyota dealer, made an appointment, then limped to a dealership for evaluation and service. while on the way to the dealership, the brakes were erratic; sometimes the brakes and pedal acted normally and other times it would go down a long way before braking. the warning lights stayed on.

When start the car, passenger side both "airbag off" light and "airbag on" light on for a second, then both lights off, then "airbag on" light on and keeping on.

2010 prius started up in the garage 3 hours after being shut down. i am certain the car was not still running while we unloaded groceries from hatchback and left the garage. * nothing was retrieved from the front seat so no accidental start could have occurred. * my son "heard it start" almost 3 hours after the vehicle had been shut off while in another room near the garage. * i heard nothing from the upstairs. * the prius key fob was nowhere near the vicinity of the vehicle at the time it started nor was any person. in fact, both key fobs were upstairs and only the currently used 1 had a battery and was stored inside a tin so as to always know where it was. *toyota executives were made aware of incident but essentially denied the toyota could start without the key fob: "toyota is not aware for any possible way for the vehicle to be started without the key."

I have been experiencing issues with my brakes for last few years. i had received a letter from toyota in 2019 stating that my car has faulty brake system and toyota will repair the issue by replacing faulty brake components free of charge. however local toyota dealer refused to complete the repair multiple times. first they suggested that they have not received any letter from toyota. then they said that they were busy and i should come back later. they also told me to put the car on park gear or re-start the car to get rid of abs lights. also they stated that repair can be done anytime later until my car reach to 150,000 miles. last week i went back to toyota dealer again. this time they told me i should have repaired the car through extended warranty. i was also told that their former service staff must have misguided me. i contacted toyota customer care and complained about this issue. they confirmed that they can see in their system that i had visited the dealer for brake issue back in 2019 and repair was not done. however they suggested that toyota will not provide any help now. because issue is between me and the dealer.

Abs and traction lights on abs system not working was informed it is the break booster and abs pump same as recall that ended in 2021 , i was never informed of recall and have found many other owners were not informed. at the cost of cars today many can’t afford to buy new and this is a serious safty issue toyota should take responsibility for the repairs

While driving on 01/31/2022, i noticed several warning lights came on suddenly on the dash and heard intermittent beefing noise while driving. i took my car to the dealership and they found m r&r brake booster and booster pump needs to be replaced and they informed me that recall warranty time of that equipment has expired and i paid for it to be replaced costing me $3539.76. toyota motor company told me that they are not responsible to repair or replace it.

About 3 weeks ago, i was driving down pch around manhattan beach , california. suddenly the dashboard lit up like a christmas tree , the abs light , brake light , pre-collision system light and a yellow triangle with an exclamation point in the middle all turned on at the same time , and a loud beeping alarm went off inside the car that was deafening and most importantly the brake pedal turned very hard i had to stand up on it just to slow down to brake and my braking distance tripled . i almost hit the car in front of me . i had this terrible feeling that the car isn’t safe to drive . it feels like the brakes failed. luckily there was an autozone nearby so i pulled in their parking lot and borrowed a code scanner . c1252 , c1253, c1319 was the codes that showed up all indicating that the abs system failed and the results is recommending to replace the brake booster pump and the abs module. there’s also a leak of some kind within the abs system. i brought it to an independent auto shop near my residence and the shop told me that the and power brake booster and the abs module needs to be replaced . the repair will cost $2.000 to get fixed in which i can not afford. i was able to seek help from my siblings and was able to come up with $1200 . so i’d figured the shop owner might be able to let me pay half first and half in 2 weeks or so when the car is fixed. but when they replaced the 2 parts with brand new ones ..yhe ecu isn’t communicating with the abs module . the shop suggested that we bring the car to a toyota dealership to get it diagnosed to figure out why the abs system is still faulty even when the abs power brake booster and abs module were replaced with new ones . toyota dealership said they will charge $795 just to diagnose it . i almost passed out in shock.. i haven’t worked since the brakes failed on my car and i can’t afford to pay for the repair . please help.

Hello there, my name is lashyrah and i do not know much about cars so most of this is unknown. the person i bought my vehicle from did not give me much information and i was desperate at the time so i bought it. most of the lights on the dashboard are on: abs, brake system, engine, tire/safety alert, fuel pump reset warning, and stability control are lights that come and go. i have used the code system to try to reset these things and they go away then pop back up. sometimes while i am driving, all the dashboard lights disappear and the breaks start getting really touchy and it feels completely different driving until the previous lights all come back on. this has been an issue before and when i last went to toyota to get my car serviced, i asked them to check the lights and system, and if they could do a multi-point inspection. they wanted me to pay $300 just to find out why the lights keep coming back on. please help me get this fixed at no cost i am a single mom and college student working part time so i need my car to get around or a free loaner car to get around until this is fixed. i strongly feel these are recalls that did not get taken care of or are not showing up in the recall system. i need assistance as soon as possible and would like to know my options, especially after getting a notice in the mail a few days ago from toyota about my car possibly being affected. my fuel gauge is also empty at around 3 bars or sometimes 2 bars instead of going all the way down to empty, costing me more money on gas having to fill it up more often. thank you for your time and help.

While driving, left dash-light cluster and abs triangle illuminated in-traffic with no visual pre-warning or audible alarm. pedal pressed full force to bring car to stop and not plow vehicle in-front. owners manual & internet suggests abs & booster pump failure. call to mechanic also suggests booster pump and abs module as possible basis for trouble lights. arranging transport to prius specialty shop (not dealer) for further diagnose. no collision no injuries. note. full service brake rotors & pads completed 27-days earlier and only 671-miles driven since costing $946 paid. no issues discovered by reputable prius shop as to noise, leak or visual other. r.

The contact owns a 2010 toyota prius. the contact stated while driving 40 mph, the abs and traction control warning lights illuminated along with several unknown warning lights. the contact also stated that the brake pedal would depress to the floorboard while in operation. the contact took the vehicle to an independent mechanic who diagnosed the vehicle with a defective brake booster pump and abs control module. the manufacturer was notified of the failure and informed the contact that there were no recalls or warranties on the vin. the dealer was also notified and confirmed that the vehicle was not included in nhtsa campaign number: 10v039000 (service brakes, air) which he linked to the failure. the vehicle was not repaired. the failure mileage was 130,000.

After descending a long mountain highway in our 2010 toyota prius and coming to a stop at the bottom the brake pedal travel suddenly increased, brake effectiveness decreased, and many dashboard lights suddenly came on including the brake system warning light and stability control system light. the next morning the dealer diagnosed a brake booster failure and prescribed replacement of the brake booster and master cylinder. since this was a safety issue we had them do the work at a total cost to us of $3,363.93. they covered a rental car for us for only part of the repair period, which took 2 weeks.

I was driving my car with my daughter and was about to stop at the intersection and at that moment i realized that the car was not slowing down. abs, brake, and traction control lights up on the dashboard. i was very scared and pressed the brake to the end and only then the car was able to stop. further i found out that this is a very common problem for this model, but toyota does not recognize this.

Brakes became soft the stopping distance grew.all my dash warning signs lit up. why was my car to repaired in warranty or recalled when the problem was a manufacturer error? toyota can't pick and chose which cars they will fix when they all have the same problem. i am attaching a 'customer support program' sample and my car falls under the primary coverage section. my car was diagnosed at a dealership on 5/14/2021. but not fixed under warranty or recall. toyota has recall on brakes for many of the newer cars too. same issue.

My brakes are failing. the brake booster leaks. the stopping distance is greater. all the warning lights are on on the dash. error code c1391 on the unit. two dealers would not repair it under warranty or recall. they gave me a price of $2600-$2800.the situation still exists. the car has had the engine replaced out of warranty but by the dealer but the brakes were not replaced as a preventive measure.

The contact owns a 2010 toyota prius. the contact stated while driving approximately 70 mph, the vehicle suddenly stalled. the contact stated that the power steering and power brakes failed. the contact stated that the "check hybrid system" and "check battery" warning lights were illuminated. the contact steered off the roadway safely; however, he was unable to restart the vehicle. the contact had the vehicle towed to an independent mechanic, who diagnosed the vehicle and determined that the inverter needed to be replaced. the vehicle had not been repaired. the contact researched online and related the failure to nhtsa campaign number: 18v684000 (hybrid propulsion system). the manufacturer had not been informed of the failure. the failure mileage was approximately 387,000.

Engine is taking in coolant problem

Brake, abs and traction control warning lights went on when i was driving. i was able to brake but it was not functioning at 100%. the local mechanic was able to scan the code to get the c1391: abnormal leak of acc press error. the warning lights remain when i drive or parked. i no longer feel safe driving my vehicle. i plan to take my car to the toyota dealer for further diagnosis and repair. i was informed that this is a very costly repair.

Brake booster actuator internal leak. toyota refuses to cover the repair for the known defective and previously recalled part. see recall "d0h" and "customer support" campaign "zjb" from toyota. these are critical braking parts that control abs, traction control, stability control, front/rear brake bias, regenerative braking and brake pedal feel and pressure. loss of braking and all previously mentioned safety features occurs when the car sets the error codes, disabling and crippling the braking system. longer stopping distances and much less responsive brake pedal is immediate. this part costs $700 from the dealer and they want over 2000 to fix the car due to the known defective, recalled part. this affects most toyota hybrids of this era. the prius is especially important to get recalled immediately, due to this being a common taxi and rideshare car, carrying multiple lives and heavier loads, in more severe operating conditions. please look into this!! toyota corporate has been called and they refuse to help or acknowledge the problem.

There is a long-standing problem with the instrument panel being very difficult to see when operating the vehicle on a very sunny day. it is very dim even when the "instrument panel light control" is adjusted, especially when wearing sunglasses. no response by dealer.

The brake booster assembly and pump failed in my prius. this causes the brakes to barely function. it disables both abs and traction control. i nearly ended up running a red light and getting into a major collision with my three children in the car. the abs, traction control, and brake lights are all illuminated. toyota advised they are aware this is a common failure but refuse to fix it. a dealership inspected it to confirm the flaw. toyota will not fix it so i am forced to drive this vehicle with barely functioning brakes with my 3 children in the car still as i have no choice.

I was driving my 2010 toyota prius and my car started beeping when i was driving when i tried to slow down the car was not able to stop the breaking system abs started displaying and my car started to beep and it won’t stop beeping. i did take my car to the dealer for a recalled inspection after my car broke down and i was no longer able to drive for my own safety. after i took the car to downey toyota for hybrid recall they didn’t tell me anything but on the document they gave me it did state that the abs was a problem. now my car is still not able to be used because of my own safety concerns since the vehicle won’t break when i put the brake pedal and a none stop beeping sound that won’t stop at all.

Own a 2010 prius w 110k miles on it and now hearing brake booster buzzing every minute when car is on when im sure its not suppose to be going off that frequently. and of course i missed the recall date.

Driving when i had to stop because of traffic light. almost ran into a car because my brakes did not function correctly. abs light and brake lights in dashboard came on. pulled over. called tow truck. had it towed to dealer. brake booster and master cylinder were replaced.

Tires losing air and noticed the rubber breaking down and separating from the sidewall on all four tires. took into evans dealership and they informed us the tires were a safety issue and tried to sell new tires. they told us the tires were made in 93 but we bought in 2016, so we looked up and dot number on tire (only had u093). the service tech did not understand the dot numbers since it was missing the last four numbers. they do have a date on the paperwork u09304160416 the tires only have approximately 25, 000 miles and car is garage kept. rubber should not be breaking down. what can we do? we had no idea about the date until they pointed it out. legally these tires are a safety issue. tires p 195/60r15

My 2010 toyota prius seemed to have a faulty abs actuator/ boaster pump for years but i did not know it until recently. for years the car would display the abs, traction controls, and brake light for 50 miles and then go away but the most recent time it did not go off. the actuator continuously runs and you can hear it consistently buzz every 5-10 seconds. the brake pedal require a lot more force in order for the car to slow down and the car jumps forward when depressing the brakes suddenly. in the past the brake would require much more force but after a few miles on the road the light would go off and the car would seem to function as normal, but most recently as of last week the light would not go off and the brakes require a lot of force still after doing almost 400 miles. i had 2 near misses once almost hitting another car during a rainy day and another missing a stop sign by almost half a car length. i took my car to the dealership and they stated that the error code is showing a faulty abs actuator but the rep told me it should still be fine to drive if i do not want to pay the out of pocket cost and get it fixed immediately. this is a major safety concern for me and my family and even though i been servicing my car for year at the toyota dealership it was never brought to my attention. only recently when i had the near misses and had my mechanic run test on it did i realize. i then took my car to toyota for routine maintenance and it was confirmed that the abs actuator/boaster pump was faulty, yet they offer no remedy and they never even notified me of this faulty oem issue until i brought it to their attention. the dealership said my vin did not qualify for any recall or customer satisfaction proposal (csp) and that if i wish to fix the brakes/actuator issue it would be an out of pocket cost of a few thousand dollars. this is unacceptable and action needs to be taken immediately to recall and rectify this before innocent lives are lost due to brake failure.

The braking system malfunction and it's available for inspection upon request. i was almost get into accident when i was driving around 65mph on i-495 because of the fail brake issue upon online research, it turns out this is a common safety problem on the 2010 prius and toyota only issue extended warranty but not recall. the abs light, slip indicator light and brake system light all come on at the same time before i experienced the brake system failed

My 2010 is covered under a recall. i had total brake failure and the dash light up like a christmas tree. brought in before the recall was released and it was repaired under my extended warranty. then got recall notice, so i guess there was an internal fund transfer.

The driver airbag deployed without an accident while driving in the highway. the airbag deployment caused near control lost of the car. i was lucky to not have any other cars near me so i managed to get the car safely out of the highway. the airbag deployment was scary and caused me not able to see through the windshield due to the gas from the airbag.

The brake cylinder and brake pump assemblies broke down in the middle of the highway. the abs, brake, vsc, and traction lights lit up unexpectedly after ~1 hour of driving. i was able to get the car to the dealership and the service advisor noted that he was surprised that we made it as far as we did without a complete failure of the brake system. he advised that it was not even safe to drive the car around the corner for a few blocks because of the brake system malfunction. they provided an error code of c1391. this is a full failure of the brake system that makes the vehicle unsafe for street operation. this complaint adds to an already well-documented problem with these issues that toyota acknowledged through a wholly inadequate "voluntary customer support program" which expired after the earlier of 10 years and 150,000 miles [link: https://bit.ly/3cntosu], which for all 2010 priuses expired in 2021. the issue also appears similar to the ones reported in defect petitions dp19-004 and, indirectly, pe10006. this was also the subject of a lawsuit in 2020 that was since withdrawn by the plaintiff (turner v. toyota, case no. 5:20-cv-00320, cd cal). there are dozens of written reports and videos of people resetting their brake warning lights with paperclips. this is a major safety hazard for those 2010 priuses that are still on the road and should be remedied by a recall.

I had just gotten back in my car from a quick store trip. my prius turned on like normal but soon after when i was driving different kind of warning lights turned on. my steering was affected ,the car slowed down considerably to the point i was almost rear-ended. the triangle of death, check engine, brake and steering lights all came on with the check hybrid system warning. before this i had no prior issues with my car. i had it checked by an independent mechanic who states it is the inverter that caused this

I was driving home from work when all the warning light all came on at once. the car suddenly stopped accelerating and the “check hybrid system” was showing on my dash. i was lucky enough to be going down hill so i can make it to a shoulder to get off the road. tried troubleshooting everything but to no avail and needed to get towed because the prius would not move at all. haven’t got the vehicle checked yet because the vehicle will not move and can only be moved if towed.

Car slows down to a stop when driving on the freeway. with no power to accelerate, it makes it hard to get to the side of the road to be towed. been to the dealer twice to address the problem, and was told that if i don't pay $200, that there is nothing they can do. then when i did pay the money for evaluation, they told me the problem could be one of several things that would start the never-ending process of repairs that will keep me paying until they solve it. i would think that with a $200 code reading, that the dealers software could narrow it down to the exact repair needed. i mentioned to the dealer about the jov update i had done earlier to the car, but dealer refuses to recognize that there is a recall on my vehicle, and that i needed to pay money(that i don't have) to do anything. my check hybrid system light and orange triangle comes on when the car dies

My 2010 toyota prius (jtdkn3du3a1307523) had the abs/brake warning/traction control (vsc) lights come on at the same time and i lost a significant portion of my braking ability, while driving. i was able to pull into a shop. the mechanic connected a code reader to the obd ii port and found the code dtc c1391. it is a failure with the abs booster pump assembly and accumulator. i called toyota corporate line and they said there was an expired customer support bulletin, which i did not receive mail alert for, and that it is not a recall, and that the customer is on the hook for replacement of the failed component. they repeatedly told me it was not under recall, even though internet forums all mention it as a recall campaign. i called auto shops in my area (specializing in toyota and japanese makes) and they all did not want to perform the repair as they found it too complicated to do, and told me toyota has a recall campaign and advised i call toyota corporate to get serviced.

The abs, vsc/traction control, and brake system warning lights all came on at the same time in my 2010 toyota prius. i almost lost control of my car's braking ability. afterwards, the hybrid system does not perform its regenerative braking/recharging any longer. and the cruise control mode doesn't work also. the dtc from the obd2 port is c1391 - abnormal leak in the brake fluid accumulator. i found out that this issue is widespread among gen 3 priuses, but toyota has not made this officially a recall campaign, but classifies it as a "customer support bulletin." but the issue is dangerous enough that it should be a recall item. i moved homes in fall of 2018, and toyota says it mailed out a letter about this brake issue and resulting campaign, but i never received the letter. i was totally unaware that this was a safety issue, that toyota acknowledged it, and that this safety issue with an ongoing "recall" campaign with an expiration date. toyota denies that this is a recall issue, and will not provide this service. i would like for nhtsa to reopen and investigate this issue, and make toyota issue a general recall campaign to resolve this dangerous safety problem with the car.

The contact owns a 2010 toyota prius. the contact stated while his wife was driving 40 mph, the traction control, abs, brake warning light, and other unknown warning lights were illuminated. the contact's wife was able to drive to her residence. the contact stated that he was an independent mechanic and he had diagnosed that the failure was related to nhtsa campaign number: 13v235000 (service brakes) however, the vin was not included. the vehicle was towed to the dealer but was not diagnosed nor repaired. the manufacturer was notified of the failure, but no assistance was provided. the failure mileage was approximately 192,000.

I noticed that my brakes felt mushy when applied. the abs light came on in my car. i took it to 2 different toyota dealers and both said that my break boosters were failing and would need replacing. i had 125,000 miles on my car. the brakes were working adequately at that time, but i was aware that they could fail at any time and put me in danger. i was charged $3637 for diagnosis and repair on 12/6/22.

The contact owns a 2010 toyota prius. the contact stated that while driving at various speeds, the vehicle started to hesitate. the abs and traction control warning lights were illuminated. the contact stated that there was brake message displayed. during the failure the brake pedal had to be depressed twice before the vehicle responded. the vehicle was taken to the local service center who diagnosed that power brake booster and master cylinder needed to be replaced. the vehicle was not yet repaired. the manufacturer was notified of the failure and informed the contact that the vehicle did not qualify for the extended warranty related to the failure. the local dealer was not yet contacted. the failure mileage was 135,000.

Abs system displayed airbag symbol displayed brake symbol displayed seat belts light flashing airbag system showing off. toyota dealership is aware of the problem with the abs system along with the items mentioned. accident could have been avoided contact if the abs system was working. airbags did not deploy. advise toyota corporation on 27 february 2023 file number 230-227-00 2210 in regards to the abs they were also advised of the airbag symbol displayed in the seat belt fasten flashing on driver side when an individual is seated in the car and buckled in. vehicle has not been inspected yet however on monday 6th of march it will be inspected by copart, by the direction of the usaa insurance company.

Abs system and traction control lost. abs booster pump and master brake cylinder broke down. they should be life long parts. brakes lost its function on highway and was pretty dangerous. abs light, traction control light and brake light on. dealer refused to change on their own.

Thank you

Nothing wrong with it

I was driving in my neighboorhood and as i went up the wall bridge my acceleration stalled and my abs light, check engine light, and check hybrid system light came on simultaneously and started beeping. at the same time, i lost my braking ability completely. i had to swerve off to the grass in the hopes of not hitting turning traffic at the stop sign. luckily, it stopped before doing any major damage to anything. thankfully, i was close to home and was able to put it in my driveway safely. the check engine light then cut itself off, but my brakes remained completely nonfunctional. if this had happened on the highway or a busy road i'm sure it would’ve been much worse.

Purchased new a 2010 toyota prius third generation level 4 in july of 2009. hybrid battery pack failed just after 150,000 warranty lapsed at 155,000 miles. january 2023 floods in merced, ca damaged one of blocks in hybrid battery pack driving through waters at 191000 miles on odometer. this threw dtc poa 080 'check hybrid system' message. the following month february 2023 at 191500 miles i notice loud cooling fan for hybrid battery operating for the first time ever! fan is located in rear seat behind front passenger. air vent is clearly visible. i believe defective fan led to overheating of hybrid battery premature failure at 155,000 miles.

I was driving and all of the sudden lights came on, on the dashboard and when i started to slow down i noticed the brakes were very "mushy" and barley worked. i then drove it directly to the dealership and on the way the lights went off, and brakes went back to normal. this is a very dangerous situation for anyone to be in and i don't know why nhtsa has not made this a mandatory recall for toyota, i know why toyota does not recall $$. they are now making $$ on parts and their dealers are making $$ on this service. i did not find a specific recall on the nhtsa website but i did find a recall # that i will be looking into in more depth. that recall number is 13v235000. the dealership said it would cost $3,000 to replace the brake booster pump assembly and master cylinder. if i were someone with very little funds to get this repaired then i would drive the car as my only source of transportation. this type of repair should be recalled and nhtsa should get this resolved with toyota asap.

2010 toyota prius. consumer writes in regard to paint issues on vehicle. the consumer stated because of the original paint problems, "a customer support program is provided by toyota for vehicles with the original factory blizzard pearl paint. if the condition is verified the specific panel affected will be repaired."

My prius 2010 has thrown the abs, traction, and brake hud lights all together. i took it to an autozone and scanned the code to get the c1391: abnormal leak of acc press error. many prius 2010 have this issue, i'm sure i'll need to replace the actuator and/or accumulator and i know that will cost a good bit, i hope toyota could help us fix it.

Almost caused a major accident. brakes failed with no warning!

Took my car to toyota dealership to get remedy j0v nhsta recall id no. 18v684 fixed. dealership has refused to work on recall and has told me i need to pay out of pocket for repair because my car does not fall into certain codes yet it’s a specific recall that needs to be done on my vehicle

Hybrid system shut down while driving. cleared at deal ship twice. happened two more time. dealership claims they were unable to recreate the issue.

The braking system developed a leak in the accumulator causing the whole braking system to fail and turn the abs light on in the car as it leaked brake fluid into the brake booster from the master cylinder

There was some kickback or resistance when engaging the brake to start the car. when the car turned on, the brake light, abs light, and traction control light lit up. i took the car to toyota service, they stated that the brake booster pump was defective and needs replacement. i see that there is not an open recall for this vehicle, however there was a recall #13v235000 that was sent out in 2013 with the exact same issue for 2010 toyota prius. we bought the car as a certified pre own in 2015, so we did not get this notification. i am trying to figure out why this car does not fall under the recall category? thank you.

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed, the abs warning light and two other unknown warning lights illuminated. the contact stated that the brake pedal went to the floorboard while depressed. additionally, the contact stated that while self-inspecting the vehicle, he became aware that there was no brake fluid in the brake fluid reservoir. the contact stated that when the vehicle was self-inspected for a second time that same day, the brake fluid was full. the vehicle was taken to an independent mechanic, who informed the contact of an unknown recall for the brake booster. the vehicle was not repaired. the manufacturer was not made aware of the failure. the approximate failure mileage was 85,000.

Abs brake booster failure. vehicle with approximately 140,000 miles. previous safety notice expired that covered 10 years or 150,000 miles

I took my vehicle to my mechanic at my independent service center because i experienced shaking/significant vibrating at 60 mph. i had also experienced a loud noise that only lasted about 2 miles. he found that the right rear brake unit, specifically the caliper, had seized. i contacted toyota of america because there was no brake warning light to alert us of this situation. i received a call back from david from sloane toyota in glenside, pa, who confirmed that the caliper seizing would not cause the brake warning light to appear. he also indicated that the caliper is not something that is routinely checked as part of state inspection, or the regular maintenance schedule. i am deeply concerned that this mechanical failure of the brake unit could have resulted in death(s). i request that toyota vehicle owners and mechanics be alerted to this, specifically the fact that the brake warning light does not alert a driver of this brake part failure. further, i request that an inspection of the calipers be included in the routine maintenance schedule and annual state inspection. thank you for the work that you do to keep us safe!

My abs, break and anti-skid lights came on while my vehicle was parked. the abs system shouldn't fail on a car. many other 2010 prius owners have reported the same problem. toyota had break system recalls back in 2010 and 2013. i believe my car may should have been part of the recall, but was overlooked.

Abs pump booster failed. hard to stop the vehicle. almost had an incident. trouble code c1391.

The break booster started making a noise and my car should have fallen into the range of the previous recall for the exact part. i cant afford to change it so i continue to drive it and all of sudden the breaks are so hard to push and a constant buzz is going off! autozone confirmed it was the break booster ans abs then a private shop did also

Even though a related recall has already been performed 4 years ago, my vehicle is exhibiting the same brake safety symptoms: - 3 dashboard lights all illuminated: brake, abs, and traction control (anti-slip) - brake accumulator pump noise occurring at 5 second intervals - regenerative braking and abs are non-functioning - error code c1391 appears via obdii the above symptoms appeared two weeks ago (6/14/2023), and on 6/16 an independent service center that specializes in foreign vehicles (including toyota) confirmed the symptoms and error code, and said that the vehicle is unsafe to drive due to impending brake system failure. toyota dealer indicated newer brake system parts are available to address the issue, but would need to be installed at my cost. the symptoms appeared while driving the vehicle at freeway speeds commuting to/from work. the vehicle is available to be inspected, however, i have already scheduled a repair (at my cost) because we use it daily for work.

There's existing problem right now in my vehicle that braking is less responsive and also the abs, emg brake lamps and traction control lights are on the whole time on my dashboard. i took it to the mechanic and he found out that theres a problem with the brake booster pump assembly which developed a crack inside the accumulator housing. as result nitrogen gas could leak into the brake fluid and gradually cause a loss of power assist. under certain circumstances, this could affect stopping distance and increase the risk of a crash.

Brake system failure. abs light / brake light / traction control light. low mileage car. likely the last hybrid i would buy. $4000 to fix. almost what i paid for the vehicle. there is a recall but expired. should be by mileage not time!

Brakes take longer to apply with weird noise. there is a weird sound. brakes are fine not worn. mechanic says bad abs actuators which should not have failed since should last life of car. there was a recall on this but my car not in the vin search not sure why. all problems described in that recall is what i am experiencing.

Brake booster failed while driving. warning light abs, traction control and brake light lights up. lost power brake. car is hard to stop with the manual brake in the fail safe mode. with c1391 code logged. toyota had an zjb warranty extension but my car is not covered because the warning light did not show during the 10 year window. the brake booster fail appear common and should be cover by a recall instead of a warranty extension.

My brakes are not working effectively. they are not engaging as they are meant to.

To submit a claim to the nhtsa regarding my 2010 toyota prius (vin [xxx] ), i wish to highlight a concerning issue with the brake booster, actuator, and brake booster pump assemblies. this malfunction has the potential to lead to brake failures, posing a significant risk of collisions with other vehicles. the presence of a diagnostic trouble code (c1391) and the illumination of abs, traction control, and exclamation symbol lights, coupled with an audible whirring sound during braking, underscore the confirmed nature of this problem. this whirring sound initially emerged a year ago, accompanied by temporary dashboard light activation, which eventually subsided, while the whirring sound has persisted. toyota has initiated an extended warranty program labeled (zjb), encompassing a span of 10 years from the initial usage date or until 150,000 miles are reached, whichever comes first. regrettably, my vehicle's mileage has exceeded 182,000 miles over the stipulated 150,000-mile threshold, and its age surpasses 13 years, rendering it ineligible for inclusion in this program. the actions of toyota appear to prioritize financial gains over the well-being and security of countless drivers and passengers who are potentially endangered by these defective brakes. their stance is exemplified by the reluctance to offer a comprehensive solution. i find myself compelled to bear the burden of approximately $3,000 in brake-related expenses at dealerships—an unjust imposition on consumers, given toyota's distribution of flawed components that jeopardize safety and lives. toyota's response has been inadequate, limited to extending warranties and performing repairs solely on vehicles that have already experienced brake failures. this approach neglects the prevention of potential injuries or fatalities that could be averted through proactive measures, such as issuing a full-scale recall. in light of these circumstances, i am seeking redress through the app information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

The contact owns a 2010 toyota prius. the contact stated while driving 45 mph, there was an abnormal sound coming from the front driver’s side of the vehicle. the contact stated that the traction control, brakes, the pre-collision system (pcs), and the abs warning lights were illuminated. the contact took the vehicle to the local dealer, where it was diagnosed with needing the brake actuator and the brake booster to be replaced. the vehicle was not repaired. upon investigation, the contact associated the failure with the tsb: pol1803, however the vehicle was not included. the manufacturer had been informed of the failure. the failure mileage was approximately 143,000.

Hello on my 2010 prius the abs, brake, traction control lights are all on lit up on my dashboard. brakes are making loud noise when i stop the vehicle. i took the car into my local dealership service department. i’m being told that the brake booster and master cylinder needs to be repaired. this was a part that was put under an extended warranty with toyota but now it’s no longer being covered by the warranty. so they want me to pay out of pocket to fix. i would like to report that they should honor the warranty agreement for my vehicle.

Brake system failure. abs light / brake light / traction control light. there is a recall but expired. code c1391 need to replace brake booster and brake pump. recall should have included my car. 1,500.00 plus parts only. recall should be extended.

Known problem for prius with limited manufacturer liability. my breaks started failing, i am being quoted at $4000 in repairs and labor. my car is 3 years older than the recall parameters but within mileage. manufacturer won’t cover anymore since it’s past due

Affected by the recall number 10v036000, the 2010 toyota prius is manufactured with a defective brake booster and master cylinder system which causes defect of the brake system, and causes my vehicle to often lose power in abs and randomly lose abs power braking, making brakes hard, and makes for longer stopping distance. this is a problem for many and obvious reasons on the road regarding safety. all vehicles should have optimal braking systems for the road, and should otherwise be repaired at no cost if the car is manufactured with defect. this has caused no accident for me yet but the abs has failed on many occasions. i have read at least 100 cases of this given vehicle under this recall being caused an accident with faulty brakes, and sometimes complete failure to stop which is extremely worrying. this recall excludes vin numbers past a certain date, yet the recall in question is certainly still affecting many cars, as capistrano toyota has also called for petition of toyota to repair at no cost for all affected vehicles. yet all dealerships have denied my request and toyota has no formal coverage regarding the rest of the faulty vehicles they manufactured.

I was driving and all of the sudden lights came on, on the dashboard and when i started to slow down, i noticed the brakes were very "mushy" and barley worked. i then drove it directly to the dealership and on the way the lights went off, and brakes went back to normal. this is a very dangerous situation for anyone to be in and i don't know why nhtsa has not made this a mandatory recall for toyota, i did find a recall # 13v235000 (which needs to be extended). the dealership said it would cost $3,000 to replace the brake booster pump assembly and master cylinder. this type of repair should be recalled, and nhtsa should get this resolved with toyota asap.

Due to insufficient corrosion protection, the rear brake line of my 2010 prius burst as i pressed the brake pedal in my driveway. it dumped all of the brake fluid onto the ground within a couple of minutes. imagine if i had been driving!! there could have been a serious crash!! this was sudden. there were no brakes! pedal lost all pressure and went to the floor when pressed. lots of warning lights and alarms screaming inside car. the vehicle has been inspected and repaired at the toyota dealer as of 10/03/2023. i have pictures of the failed part when it was installed on the car. if the dealer is contacted quickly, they might still have the actual failed brake line (which i was charged disposal fees for.) this was very scary and numerous lives could be at risk due to the popularity of this car and its use in rideshare/taxi service. there were no warnings prior to this. brakes worked normally. car is well maintained with dealer service records. there is no excuse for not properly trading such a critical part for corrosion, just to save money. peoples lives are at stake!! it's the brakes of the car!! someone needs to investigate this! i have pictures and receipts i can provide.

The breaking lights, skid lights and another light associated with breaks came out and i lost the abs abilities, the hv battery is not charging while breaking. these lights comes out randomly. very risky especially while breaking.

My car malfunctioned causing me to lose control of the car and it crashed into 38 woodcutters lane first, and 33 woodcutters lane second.

Excessive oil consumption, particularly with highway driving. i have had this car for about a year. i only noticed that the oil was nearly empty when the engine was shaking while idling at an intersection. no warning lights for oil pressure or level ever came on, it would occasionally "ding" for oil pressure, but barley long enough for me to even read what the warning was. by excessive, i mean very excessive. first oil change after only 3k, almost empty. road trip, mainly highway only about 600 miles, nearly empty. if i top it off, i check it constantly. city driving (more electric) it may burn a quart every 1-2k miles, highway more. i had the egr, manifold and plugs serviced/replaced, it improved slightly. i'm having more work done now, but after reading so many similar complaints online, i find it hard to believe this isn't a recall. an engine sputtering and nearly dying while idling is not safe, especially with no warning lights on! i contacted toyota, they said they had not recalls or consumer confidence programs for complaints of oil consumption and/or piston ring seat problems in these vehicles (seems to be the primary cause). i did see a class action for many other toyota 4cyl engines due to excess oil consumption.

The contact owns a 2010 toyota prius. the contact stated while driving at various speeds and depressing the brake pedal, the brake pedal was firm and difficult to depress. the contact stated that that the brake pedal was pumped to stop the vehicle. the contact stated that the abs and stabili-trak warning lights were illuminated and an “exclamation mark" message was displayed. the contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the brake master cylinder and brake booster pump needed to be replaced. the vehicle had not been repaired. the contact researched online and related the failure to nhtsa campaign number: 10v039000 (service brakes, air). the manufacturer had not been informed of the failure. the failure mileage was approximately 138,000.

The airbag sensors for my passenger seat do not work. regardless of if there is someone sitting in the passenger seat, buckled it, the system indicates that there is no one sitting in the seat and that they are not buckled in. this is of course a safety issue since the airbags would likely not go off even if someone was sitting in the seat. my vehicle is available for inspection upon request. they first appeared shortly after i purchased the vehicle from the last owner. the vehicle was lightly used and is very clean, and i have no reason to believe the passneger seat was abused in any way. my concern is this: this airbag sensor issue is a recall i have seen for other 2010 toyota priuses. i understand that in the systems, this recall does not show up for my car. however, i think it's interesting and worth looking into that i have the same make, model, and year, and my vehicle is having the exact same issues. this is an issue that was not triggered by any crash/collision, and i did not have anyone even sitting in my passenger seat prior to this issue, so it seems to be purely a system issue that i could not have prevented myself.

Hi i want submit issues with the master cylinder and abs pump assy i have 2 vehicles same model with average same mileage and both had issues with this system if i drove any distance below 25 mph in a constant time the dash lights comes on traction control, abs light, brake light , and the brake pedal goes low and barely brakes make this situation dangerous when i stop if you try turn it off the engine and on again lights stay there but if i reset the codes the pump works again for some while and then again when you don’t expected lose pressure and i am really afraid for my safety and my family, and i am not the only one with this problem is too many prius owners who have the issues i went from dealer and they advice $3000 dlls fix situation who motivate people to lose money for $1200 in parts and $1800 dlls in labor for something they can resolve it because in reality is an manufactured defect

The brake booster assembly and brake booster pump have failed due to a vaccine leak internally in the brake booster. failure of the brake booster can cause the vehicle to be more difficult to stop. yes the failure codes have been reproduced. the vehicle falls “out of warranty” for a part that should last the life of the vehicle. replacement of the part is quoted over 4,000 dollars. the abs light, brake light, and traction control lights.

Slip indicator symbol, brake word, brake symbol, and abs word lit up while driving. brake pedal had to be pushed further down to stop the car. no warning lights or issues before this incident. toyota diagnosed as abnormal leak in accumulator and internal brake fluid leak, and quoted replacement of the brake booster assembly with master cylinder and the brake booster pump. there is no advance indication and the brake booster will not be available while driving. toyota recalled selected vehicles. there are currently many reports online from vehicles excluded from the recall that are affected by the same brake booster malfunction and warning lights.

A couple weeks ago we were driving our 2010 toyota prius and 3 brake lights came on: brake, abs, and a car with squiggly lines behind it. we took the car into the toyota dealership ($209) to perform a diagnostic. their results are as follows and i quote: "hydraulic brake booster pump dtc c1391 abnormal leak in accumulator. has t-sb and csp that are both expired. recommend perform repair outlined. recommend r&r brake actuator assy, booster pump assy and perform abs ecu reflash. we wouldn't have purchased this car had we known a few years later we'd be facing a $4400 charge toyota wants to charge. we don't have the funds let alone go now and purchase another car.

My brakes behave strangely cause i experience inconsistent brake feel after actuation during slow and steady application after brakes on rough or slick surfaces.also, all three lights abs light,brake light and vsc come on and off on dashboard at the same time.

The contact owns a 2010 toyota prius. the contact stated that while driving at 40 mph, the vehicle consistently made abnormal sounds and jerked forward while the brake pedal was being depressed. the vehicle became inoperable. several unknown warning lights were illuminated. the vehicle was taken to the dealer to be diagnosed. the contact was informed that the failure was due to a crack and leak in the brake booster. the vehicle had not been repaired. the contact referenced the nhtsa campaign number: 13v235000 (service brakes). the manufacturer was made aware of the failure and determined that the vehicle was no longer under warranty. the failure mileage was approximately 65,000. the contact stated this is a known manufacturing fail for the brake booster 2010 prius.

While operating the vehicle at normal highway speeds, the car suddenly had the abs, traction control, and brake lights all come on. the vehicle did not operate or sound any differently at the moment all the lights came on. however, over the next week there developed a mild humming coming from somewhere in the engine bay approximately behind the dashboard. my mechanic identified the problem as the brake booster and pump assembly failing and informed me that the vehicle may drive normally for sometime but the brakes will fail suddenly once the brake booster and pump fully fail. thus, making operating the vehicle extremely dangerous. i am currently waiting for a toyota specialty mechanic to become available to replace the brake booster and pump assembly at a cost of +$3,000. please investigate this issue, there are many people experiencing this issue with the 2010 prius models.

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed, the traction and abs warning lights illuminated. the contact stated that the brakes were inoperable. the contact stated that he was driving at a low speed and was able to safely stop the vehicle. the vehicle was taken to an independent mechanic where it was diagnosed with a failed brake booster. the contact was informed that the brake booster needed to be replaced. the vehicle was not repaired. the manufacturer was made aware of the failure but did not assist. the failure mileage was approximately 227,000.

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed, the abs and brake warning lights remained illuminated, and the brake pedal was firm while depressed. the contact stated that the vehicle failed to immediately stop while depressing the brake pedal, causing the stopping distance to be extended. the cause of the failure was not yet determined. the manufacturer and local dealer were not notified of the failure. the failure mileage was 120,000.

Recently, i had abs failure in my vehicle and warning lights came up on my dash with code c1391 which indicates a problem with brake booster assembly and pump. now i am afraid to drive it because the brakes seem that they could fail at any time and i cannot break quickly when needed. toyota is aware there is a problem with the brake booster assembly and pump based on prior customer support programs (my vehicle was not included since warning lights were not present at the time), class action lawsuits, and petitions to nhts about this issue. i believe the problem is prevalent enough and brakes are significant for driver safety that there should be a safety recall. my vehicle has less than 150,000 miles. i called toyota to complain about the problem as i know it is very common among prius owners, but they have said there is nothing they can do.

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed, the contact depressed the brake pedal and noticed an abnormal humming sound. the contact stated that the failure had been intermittent since 2016. the contact stated that the failure had become persistent. the vehicle was not diagnosed or repaired by an independent mechanic or dealer. the manufacturer was made aware of the failure but did not assist. the failure mileage was approximately 296,842. the vin was unavailable.

All the lights on my dash board came on suddenly, and the brake emergency, traction control and abs lights stayed illuminated. upon exiting the interstate i could not come to a complete stop at the end of the exit, which was very scary. fortunately the cars driving on the road the exit merges into did, so we avoided a terrible accident. the brakes were spongy and not operating properly after that. the next day with all the lights still on, i slowly drove (20 mph) to the local toyota dealer , who claimed that error code (c1391) was being displayed and according to toyota, that means the booster is or will be leaking. therefore the pump and booster needs to be replaced (estimated at $3k). no lights or errors were given before the incident, the brakes just suddenly malfunctioned. however toyota apparently is aware that the booster and pumps fail without warning, because i discovered with an on-line search that code had a "customer extension" warranty (by googling the code c1391), i called customer service but they refuse to help. they claimed i was mailed a letter in october 2018 (they didn't offer to supply a copy.) however, i never received a letter or any notice from toyota or the toyota dealer that i have repeatedly used since i bought the car in 2010 (i have had brakes replaced there when it was under 150k and no one said anything!) now they are stating that the extension has expired as it was only good up to 150,000 miles or 10 years which ever came first. i can't understand why they have a known brake issue and not replace the part when the vehicle is already at the dealer (it's there for every oil change 3 x a year!) brakes are an important part of a vehicle, a failure like this should have been recalled, and toyota should have been made to replace the faulty parts!

The contact owns a 2010 toyota prius. the contact stated that while driving 50-55 mph, the abs, traction control, and brake warning lights illuminated. the contact called the local dealer, but the vehicle was not diagnosed or repaired. the vehicle was taken to an independent mechanic and the contact was informed that the brake booster assembly needed to be replaced. the manufacturer was contacted, but no assistance was provided. the approximate failure mileage was 139,999.

I was in my 2010 toyota prius with my two children when i suddenly lost my brakes, with luck i was able to let off my gas and coast to a stop. now i am left with a 3,000 dollar repair. i now know what the price of my children and my life is worth to toyota! to find that this has already been a problem with no notification is ludicrous!

Video recording

I noticed that the ratcheting parking brake pedal has stopped ratcheting correctly, and i planned to have it inspected on the next scheduled maintenance. recently, the brake system illuminated the traction control, alb and "brake" lights simultaneously, and the braking power diminished by more than half, with no braking until the pedal was halfway down. i depressed the parking brake pedal a few times, which cleared the "brake" symbol and the problem stopped and normal braking returned. this has now happened three times with the same fix. it appears that when the "brake" symbol is no longer illuminated, the problem goes away. this appears to be a software problem that triggers a braking problem to engage the traction control and abs icons when the "brake" icon associated with the parking brake is illuminated. this web site has other instances reported with the same symptoms, and toyota had a service bulletin, which has expired, which leads to a $2000-$3000 repair bill to replace a brake booster. it appears to be software related to me, not mechanical. it poses a safety risk because braking performance is severely compromised with no warning. nhtsb needs to look into this, as rear end accidents can easily happen if strong braking in heavy traffic is required to avoid a collision. i recommend that a recall be established to fix this. an alternative cause may be a misaligned micro switch in the parking brake mechanism, which has been experiencing problems. this could lead to the "brake" light being illuminated, and sending a bad signal to the computer.

The contact owns a 2010 toyota prius. the contact stated that while driving 60-65 mph, the vehicle lost motive power and went into limp mode. the coolant temperature and several unknown warning lights were illuminated, and the message "check hybrid system" was displayed. the contact pulled to the side of the road, where he disconnected and reconnected the battery to reset the hybrid system. the contact was able to drive to the residence; however, the failure recurred. the contact used an obd reader to retrieve diagnostic test code: p261b. the vehicle was not diagnosed or repaired by an independent mechanic or dealer. the contact related the failure to nhtsa campaign number: 18v684000 (hybrid propulsion system) however, the vin was not included in the recall. the manufacturer was not made aware of the failure. the failure mileage was approximately 148,469.

The brake accumulator has failed on my prius which then deactivates regenerative braking, traction control, abs, and stability control. the lights for traction control, abs, and stability control and parking brake are shown on the dash. the result for the driver is that the brake pedal has the same pressure, but does nothing until about 25% of pedal travel. at this point, the mechanical brakes will engage and provide a very sudden and jerky application to the brakes. in other words, a very non-linear brake control is present and is incredibly difficult to predict. if this vehicle is operated on the motorway, the safety of the vehicle's occupants as well as others on the road is greatly reduced. street toyota has confirmed this issue and its effects. they want to charge $3600 to fix this issue even though the car is only worth $5k. this problem has been investigated in the past buy toyota and the nhtsa. toyota has applied an extended warranty for this part meaning that they will only replace it once it goes out. they also failed to notify their consumers about this matter. it is a serious issue that has put many lives at risk and has caused multiple injuries. it is a matter that should not be ignored by either the nhtsa or toyota.

A warranty extension went out a few years back that said one might receive a "check pcs system" warning on the dash. this has happened to us, along with 7 other lights on the dash. between the brakes being much less responsive, and all of the pre-crash warning / adaptive cruise / radar features being disabled, this could have caused an accident. the dealer checked out the car and states that the brake actuator has a leak and that it will be a costly repair - no less than $3000. this suspiciously all happened *just* outside of the warranty window (we are within the allowed number of miles but just out of time), and also suspiciously after toyota released an upgraded version of the actuator, and *also* after a bunch of people are experiencing the same failure. our best assessment at this time is that the brake actuators have a factory defect and that a recall should be done.

My 2010 toyota prius hatchback suddenly had 4 or 5 warning lights appear on the dashboard and my brakes failed to function properly. it felt like the power brakes was turned off ! although i did get the vehicle stopped, it surely was a dangerous situation. i understand that toyota knows about this problem, and have read that it was warranted if this happened before 150,000 miles. my prius has approx 167,000 miles right now and to replace the brake actuator, the cost will be $ 3 - 5 thousand dollars…absurd amount in my opinion. since this critical feature (brakes) has a long known history of being faulty on toyota vehicles it should be warranted for at least 25 years and at least 300k ! my prius is “unsafe to drive” and is nothing more than a paperweight…i repeat, toyota knows, and has known about this defective brake actuator problem for years and years!!! please lean on toyota to up the warranty of this faulty brake problem for the many, many toyota owners who have purchased the toyota product and and not screwing the public like they are doing now !

[xxx] we took in 2010 prius to toyota dealership in pharr texas because road hazard light, abs , brake and low tire alarm came on while driving car. they ran diagnostic and found out that the brake pump assembly and brake cylinder assembly has to be replaced. we called toyota cooperate to ask for assistance to pay for cost and after 4 weeks of reviewing issue they said they could not help us because the csp had expired. this car was given to us by a friend of ours and they had not used it for 2-3 years so we got it we repaired and got car running again. after we drove it we came across this problem with the brakes. this car was was built in the same plant as the other recalled cars going by by the vehicle number . we believe that the csp should be extended or changed to a recall? will you help us or direct us to whom we can contact with this safety issue? i have the toyota diagnostic report from toyota and toyota corporate letter on email. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

Total malfunction at highway speeds. very unsafe, the car completely shut off. this may have resulted in a highway fatality due to collision as the vehicle was in the fast lane. ntsa please do your due diligence and investigate the faulty, defective hybrid system as i believe the faulty inverter recall is much more larger than the original recall

See all over the internet that 2010 prius have a recall for inverter. i called the dealer they said no recall with my vin. i was told that a new inver is almost $5000 dollars. i need help i have bought 3 toyota already. please help me with good will or warrenty the inverter like you have so many other people with 2010 prius. if not i willand my family will never buy a toyota again. please call or email me [xxx] [xxx] the prius died when driving and we almost got in a major accident because it stalled with no warning. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed and attempting to slow the vehicle, he became aware that the brake pedal required excessive force to bring the vehicle to a complete stop. the service brake warning light was illuminated. the vehicle was taken to the dealer, who diagnosed a failure with the brake booster and brake master cylinder. the vehicle was not repaired. the vehicle was then taken to an independent mechanic, who confirmed the diagnosis and additionally found that there was a leak in the brake fluid accumulator, resulting in low brake fluid pressure. the vehicle was taken back to the dealer, who added brake fluid to the braking system, which seemed to temporarily resolve the failure. the manufacturer was not notified of the failure. the failure mileage was 140,000.

Faulty brake boosters that crack and leak, making brakes unusable and draining the battery (diagnostic code c1391). there was a toyota service repair where they exchanged the faulty brake boosters with properly working ones, but it has lapsed.

I’m encountering multiple dash lights with the brakes being very unreliable and no that’s no regenerative breaking. i checked with an obd2 kit and the app shows that i have a code c1391.

The contact owns a 2010 toyota prius. the contact stated that while driving at an undisclosed speed, the vehicle stalled. the check engine warning light and the check hybrid warning light illuminated. the vehicle was taken to the dealer. the contact was unaware whether the vehicle was diagnosed. the vehicle was repaired under nhtsa campaign number: 18v684000 (hybrid propulsion system). the contact stated that after the vehicle was repaired the failure recurred. the contact stated that the vehicle had not been repaired as the recall repair stated. the manufacturer was made aware of the failure but offered no assistance. the failure mileage was approximately 152,000.

I had begun to notice a slight shimmy at highway speed for a few days, but it wasn't pronounced enough to cause concern, especially since the weather was very windy and already subjecting the car to heavy crosswinds. on monday, [xxx], the shimmy became suddenly more pronounced, so i pulled off the highway ([xxx]) and parallel-parked on street in cambridge, ma. while parking, i heard a loud creaking and grinding sound, and the car no longer responded to steering inputs. i exited the car and noticed the rear driver's side wheel protruding at a strange angle from the wheel well. i called aaa and the tow truck driver discovered that, behind the wheel, where the wheel meets the rear axle, the arm had rusted clean through. in other words, the wheel had completely fallen off, and was being held to the car only by the brake line. i was towed to a mechanic in salem, ma. both the salem mechanic and the aaa tow truck driver said that they had never seen anything like this in all the years they'd been servicing cars. i told them that the car had never been in a flood or otherwise involved in the kind of extraordinary event that would cause more than typical rust exposure. had the wheel come off at highway speed, i could have been seriously injured or killed. the issue did not seem to have been caused by driver/owner oversight or normal wear and tear. it seems highly unusual and potentially indicative of a defect or manufacturing error. i hope other 2010 prius owners are aware of the vehicle's susceptibility to this issue. and i would like toyota to take some responsibility for the high cost of repair. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

Brake booster assembly failure. code c1391 - accumulator pressure leak. toyota previously agreed to extend the warranty on this part on this year of toyota prius due to the known issue and the time limit for this repair was set to be in 2019. toyota agreed to replace the unit only if it fails before that timeframe. my toyota got recently affected by this issue resulting in over $3,000 estimate for a repair as toyota no longer covers this repair for my vehicle. that’s a known issue with this part, toyota knows it’s faulty and yet no recall has been issued. now i have to pay for a repair out of pocket. i can’t drive the vehicle until it’s fixed. this should be handled as a recall with all faulty units being replaced regardless of millage. a few people opened lawsuits on this issue before and some got a settlement. i believe there is enough evidence that this should be classified as a recall and a free of charge repair should be provided to the owners. the brake booster unit has been buzzing a lot for quite a few months ( due to the pressure leak it had to work more than normal). now it completely failed with the leak being so excessive that the brakes are very soft.

My car accelerated significantly on its own while i was pulling into a parking stall in a private parking lot. it caused my vehicle to jump a curb and accelerate up a dirt divider and push over a bush that was planted in the dirt divider. depressing my brakes did not decelerate the car, so i pressed the park button to eventually stop the vehicle. i’m not sure what speed it was traveling when it accelerated, but i could smell burning rubber at the end of the incident. i’m not sure when the smell first occurred.

The contact owns a 2010 toyota prius. the contact stated that while driving at 55 mph, with the brake pedal was depressed and went to the floorboard. the contact stated that the brakes failed to adequately slow the vehicle. the abs warning light was illuminated. the vehicle was taken to an independent mechanic, who diagnosed a failure with the brake booster. the vehicle was not repaired. after investigating the failure, the contact related the failure to nhtsa campaign number: 13v235000 (service brakes) however, the vin was not included. the manufacturer was notified of the failure, a case was opened, and the contact was referred to the nhtsa hotline for assistance. the failure mileage was 120,000.

Prius gen iii has a known defect with failing brake booster parts. in nov 2023, while driving my 2010 prius (~160k miles), suddenly brake, abs, traction control, skid indicator lights popped up on the dashboard and i have lost the ability to brake effectively. there was a brake pressure loss and i had to slam hard the brakes to slow the car. the error code was 'c1391' and the mechanic diagnosed it as failure of brake booster parts abs brake booster pump (accumulator) - part#47070 47060 and brake master cylinder (actuator), part#47050-47140 and he replaced both these parts. toyota is aware of these failures which are very frequent and hence they issued a brake booster “customer service program” zjb - which extended the warranty for these parts. but many of us were not covered by this warranty either because of the time or mileage restrictions. this was a costly repair and we had to fix it out of pocket at the cost of ~$3000 as this is safety hazard without proper braking. to make matters worse, 3 months after the repair, the newly installed parts failed again and i had to go through the same repair. i called to toyota to complain about this and they cannot do anything about it and advised me to report it to nhtsa.

The contact owns a 2010 toyota prius. the contact stated while driving at various speeds, the brake pedal would depress to the floorboard initially without warning. over time, the brake pedal had become stiff upon depression with several warning lights illuminated on the instrument panel. the vehicle was taken to an independent mechanic where a code reader confirmed a defect with the braking system. the vehicle was then taken to another independent mechanic where the vehicle was diagnosed with a defective brake booster. the mechanic then informed the contact of nhtsa campaign number: 13v235000 (service brakes) which was linked to the failure. the dealer was notified of the failure and informed the contact that the vehicle was not included in the recall. the manufacturer was notified of the failure but offered no assistance. the vehicle was not repaired. the failure mileage was approximately 153,000.

Passenger side low beam headlamp has continued to need to be replaced. i was not made aware of a "customer service protection program" on this and when i contacted toyota they said it was too late for the repair, electrical harness, to be covered by their extended warranty. i never received information regarding the extended warranty. they stated they sent it to the correct address. but just because you mail something doesn't always mean it is delivered to that address. also, i had my car serviced many times at toyota dealerships and they never informed me of this extended warranty. if i had been made aware of the extended warranty i would've had it repaired in a timely manner. i have spoken to two representatives of toyota and they stated they could not help me. i'm wondering why this is not considered a recall issue as it does affect the safety of driving a vehicle and the lights stop working. this may not be the right place to ask this question but i'm hoping someone in your organization can help me.

The contact owns a 2010 toyota prius. the contact stated while at a complete stop and attempting to depress the accelerator pedal, there was an abnormal vibration coming from the brake pump. the contact also stated that when the vehicle was turned off, the vibration on the brake pump occurred, triggering the alarm on the vehicle at least one time per day, each day. the vehicle was taken to an independent mechanic where the failure was related with an unknown recall. the vehicle was not repaired. the manufacturer was made aware of the failure; however, no assistance was provided. the failure mileage was approximately 196,000.

Abs lights turned on and need replacement. this is my 3rd prius that have the issue.

The contact owns a 2010 toyota prius. the contact stated while driving at an undisclosed speed, the brake pedal was depressed; however, the vehicle failed to stop as intended. in addition, the contact stated that several unknown warning lights were illuminated. the vehicle was taken to an independent mechanic where it was diagnosed with brake system failure. the contact was informed that the braking system needed to be replaced. the vehicle was not repaired. the contact was advised to take the vehicle to the dealer for service. the contact was made aware of customer satisfaction program: c1391. the vehicle was taken to the dealer where the vehicle was diagnosed with brake system failure. the contact was informed that the braking system needed to be replaced. the contact was informed that the repair was not covered under the customer satisfaction program: c1391, because the mileage had been exceeded. the manufacturer was made aware of the failure but provided no assistance. the failure mileage was approximately 166,000.

The abs pump( accumulator and booster) are regularly failing on all toyota prius( 2010-2015). when the abs pump starts to fail, the warning lights for traction control, brake and abs come on. these lights come on at all speeds and its very hard to bring the vehicle to a complete stop when this happens. the brakes completely stop working and the brakes become rock solid. the brakes become so hard that they can’t be possibly be depressed to stop in time. i nearly missed getting killed from this as i am out of country and toyota is refusing to fix it since its not a recall and i am in canada. toyota is asking $3500 in parts and $1500 in labor to repair. i can not afford it and this issue is on all prius from 2010-2015. this is a major safety hazard and can cause serious injury and damage. toyota is refusing to repair it since they believe the cars are out of warranty. however toyota has been notified about this safety hazard arising on all prius(2010-2015) but decline to respond or take action. i urge nhtsa to take action and get this resolved as the abs brakes failing on the prius can be really dangerous and can cause life threatening accidents.

The car suddenly threw a c1391 code yesterday with no previous warning. the traction, parking brake, brake system, and abs lights are all lit on the dashboard. as this vehicle is my daily commuting vehicle, i must have the costly repairs performed, which are estimated at roughly $2,400. i will ask to retain the parts for inspection. the brakes are softer, and the breaking distance required has increased by approximately fifteen feet.

In 2015 i purchased my toyota prius in va. i now live in indiana and had my car checked for a possible sensor issue because the traction, brake & abs light were coming on and off. the diagnostic showed a brake accumulator leak malfunction. i contacted toyota dealership once i was told there was a recall. the dealership said that it was showing it was replaced in 2013 from the previous owner in va. it was listed then as a recall. i contacted toyota corporate and they said that it went from a recall to customer support with a maximum of 150,000 miles. i did not have any more problems until just recent. my argument is once a recall it should still be repaired. the part appears to be the problem. it is a safety issue and i need toyota to fix the problem. thank you!

The rear axle beam broke off near the passenger side rear wheel. the wheel flops around and the vehicle is totally unsafe to drive.

Nhtsa campaign id: 13v235000 toyota will notify owners, and dealers will replace the affected brake booster pump assemblies. the recall is expected to begin late july 2013. owners may contact toyota at 1-800-331-4331. toyota is no longer honoring this recall. they think it is acceptable for me to drive around with unsafe and defective brakes.

Toyota refuses to cover a recall that i was never made aware of. my prius need to have abs brake accumulator and other components replaced. my vin i was told had a recall but i was never made aware. i was told it may not be safe to drive my car. toyota told me i would have to cover all cost for the repair and for my family that is just not possible. for the safety of my family, i am hoping nhtsa can help me in anyway.

Heading westbound on i-70, taking exit 29 off ramp from highway, i drove over uneven pavement. my traction control, abs and brake lights illuminated, the brakes suddenly felt mushy. as i approached the stoplight at the end of the exit ramp, i questioned whether i would be able to stop. scared me immensely. luckily no cars were near me. i now do not have abs, traction control, stability control or regenerative braking.

The contact owns a 2010 toyota prius. the contact stated that while driving at various speeds and the brake pedal depressed, the vehicle lunged forward. on a most recent occasion, the contact was attempting to park the vehicle and after shifting into the park position, the vehicle lunged forward as the brake pedal was depressed causing a minor collision with a curb and another vehicle. the contact mentioned the brake pedal required excessive force in order to come to a stop and that there was an abnormal noise present. the contact was concerned that the failure would progress causing a severe accident. a police report was not filed and there were no injuries sustained. the vehicle was taken to an independent mechanic where it was diagnosed that the abs system failed and advised the vehicle be taken to a dealer. the vehicle was not repaired. a dealer was not contacted. the manufacturer was not notified of the failure. the failure mileage was not available.

Brakes started making a hissing sound a couple of weeks ago. yesterday evening when i was driving on freeway , i got an assortment of lights on my dash while driving . abs was instantly disabled and it was significantly harder to brake the car. brake light on dashboard came on. traction control light came on . it was very dangerous and it was mere luck that there was no car in the front - otherwise i could have crashed. pulled over to the side on the freeway and then came in internal roads to my destination , keeping a lot of braking distance and at slow speed. turns out this is the infamous brake booster leak that was so bad toyota was forced to create an extended warranty program on gen 3 to fix it. brought it to dealer next day. got an estimate for $4000 for "replace brake booster and master cylinder(due to internal leak)"

Abs and brake lights lit at around 141000 miles code c1391 came up during diagnosis.

In august of 2024, my 2010 prius with less than 100,000 miles - all the brake warning lights on the dash suddenly came on - without any prior warning. the brakes felt a little "funny" at the time, so i took it to my mechanic immediately because my safety or the safety of other was at risk if the brakes completely failed. my mechanic informed me that there was a tsb for the brake booster with master cylinder and brake booster pumps that toyota new about. i felt that it was imperative that this was repaired immediately. apparently toyota knew about this issue but did not notify me in any way at any time. i bought this prius new and have had regular service check ups. i had to pay nearly $5,000.00 to have this repaired which i feel that toyota should reimburse me, and any others who had this problem.

Toyota failure to honor recall. see correspondence below for nhtsa id and other detail. nthsa recall id: 13v235000 toyota case#: [xxx] very dissatisfied with mr. lxxxx's denial of our inclusion in the customer support program. he seemed to reach for every imaginable escape hatch to say "no". claiming 2 notices were sent out (to the correct address) between december 2017 and march 2018, neither of which reached me, is dubious to say the least. the likelihood of our remaining a toyota "family" with the eventual replacement of our 3 vehicles (including a previously unmentioned 2017 rav4) has shrunk considerably. shame on toyota north america. ---------------------------------------------------------- (earlier monday, october 21, 2024 at 11:31:54 pm edt) dear mr. oxxxxx: i’m writing to express my distress at being disqualified for this expensive safety recall about which i was never notified by mail and, despite receiving maintenance and inspections at the dealership in slim 2-year period between the mailer and the expiration, was not notified of the recall. the phone agent, ms. xxxxxx, was very courteous, opened the case, and informed me of the 2018 mailing about the recall, which i did not receive. i’m quite diligent about recall notices, we are a toyota “family” with a sienna in addition to the 2010 prius, and records will show we’ve always attended to recalls for which we’ve been notified, going all the way back to our first purchase of a new camry in 1997. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

Hope this message finds you well. i am reaching out regarding a potential recall issue with my 2010 toyota prius. the vehicle's vin is [xxx] , and i am currently located in the austin area. recently, my vehicle has been experiencing problems related to the brake system, specifically the brake booster pump assembly. the diagnostic results returned codes c1241, c1391, and c2300, which point to issues such as abnormal leaks in the accumulator pressure and actuator system malfunctions. given that this issue may fall under a recall or extended warranty for the brake booster pump assembly, i would appreciate it if you could confirm whether my vehicle qualifies for this service. if it does, i would like to schedule an appointment to bring my car into the nearest authorized service center to have the necessary parts replaced. please let me know if any additional information is needed. i look forward to your response and would greatly appreciate your assistance in resolving this matter as soon as possible. thank you for your time and support. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

The contact owns a 2010 toyota prius. the contact stated while driving approximately 40 mph and depressing the brake pedal, the brake pedal was stiff and required excessive force to depress. the contact stated that the abs, stabili-trac, and parking brake warning light was illuminated. additionally, the contact stated that a chime sounded and could not be turned off. the contact stated that the failure had been intermittent but was a recurring failure. the contact had not taken the vehicle to a local dealer or independent mechanic. the vehicle was not diagnosed or repaired. the contact researched online and related the failure to nhtsa campaign number: 13v235000 (service brakes). the manufacturer was not informed of the failure. the failure mileage was approximately 77,000.

Check hybrid system warning lights came on and i lost all ability to drive vehicle and had to coast to the side of the road.

The gas engine had internal destruction cylinder broke and car became unusable at 158k miles despite being a hybrid with al toyota maintenance at al hendrickson toyota of coconut creek, fl. this is unacceptable and demonstrate internal combustion engine failure that fortunately occurred near my house and not in the hiway. please notify toyota motor company because i had to buy a new car and we are seniors with limited budget. it is a severe safety concern.

My brakes stopped braking but luckily i could drive slowly into a curb in my neighborhood. god knows what could’ve happened if i was on the freeway. all the dash lights came on at the same time so i ran some codes; it came back c1391 - the brake actuator is broken. toyota will not cover it despite this being a very common issue. my car is undriveable until this gets fixed because it will not break.

Please read the attached file "prius complaint signed" for a full description. i am the owner of a 2010 toyota prius, 2zr-fxe. the warning light came up on my dashboard of my vehicle, so i took my 2010 prius to autozone, to get a free diagnostic. the diagnostic indicated the problem code of “c1256” “accumulator low pressure” for the “anti-lock brake system.” see ex. a (autozone diagnostic). it is available for inspection. according to the safety recall number “d0h”, 2010 prius model “2zr-fxe” has a “brake booster pump assembly which can develop a crack inside the accumulator housing. if this occurs nitrogen gas could leak into the brake fluid and gradually cause a loss of power assist. under certain circumstances, this could affect stopping distance and increase the risk of a crash.” (emphasis added). i have noticed that when i brake hard, it takes longer to come to a stop, which threatens not only my life, but the lives of my wife and two [xxx] daughters who also ride in this vehicle. according to the safety recall, “toyota dealers will perform an inspection and, if necessary, replace the brake booster pump assembly at no charge to the vehicle owner . . .” see id. the safety recall does not explicitly permit dealers or servicers to charge for an inspection with regards to this defect, according to the information provided me. the estimate, provided by darcars recommending replacement of the “brake booster with master cylinder with pump[,]” confirms that the issue appears to be that which is covered by the safety recall. ex. f.; see also exhibit b safety recall (the vehicle has a “brake booster pump assembly which can develop a crack inside the accumulator housing . . .”). see also exhibit e error code from darcars (“c1256 accumulator low pressure”). nevertheless, darcars refused to waive the diagnostic fee of $150 and would not repair the vehicle unless i paid them “$5,150.” see exhibit f. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

The contact owns a 2010 toyota prius. the contact stated while driving at undisclosed speeds, while depressing the brake pedal the vehicle failed to come to a complete stop and the brake pedal was firm. no warning light was illuminated. the vehicle was towed to a local independent mechanic where it was diagnosed and determined that the brake module needed to be replaced. the local dealer was not contacted. the vehicle was not diagnosed or repaired due to the cost. the manufacturer was made aware of the failure. the failure mileage was approximately 117,000.

At around 1000,000 miles my toyota prius started burning oil like crazy. the dealer did an oil consumption test and confirmed the problem. i had to have my engine rebuilt because the rings were not seating properly. i had to bear all costs even though this is clearly a manufacturing default.

The contact owns a 2010 toyota prius. the contact stated that while her husband was driving 25 mph, the brake pedal was depressed but the vehicle failed to respond. the contact stated that several unknown warning lights illuminated with an audible chime being heard. the contact's husband pulled over to the side of the road and depressed the brake pedal and the pedal went to the floorboard and the brakes started to respond as needed. the vehicle was towed to an independent mechanic where it was diagnosed and determined that the brake pads and rotors needed to be replaced. the vehicle was repaired but the failure persisted. the contact stated while driving at an undisclosed speed, the brake pedal was depressed, and there was an abnormal sound coming from the brakes. the contact stated that the brake pedal went to the floorboard. the contact then towed the vehicle to the residence. the vehicle was taken to the dealer but was not yet diagnosed or repaired. the manufacturer was made aware of the failure and offered a customer satisfaction program extended warranty repair. the failure mileage was approximately 105,336.

I recently had an issue with the brake actuator on my 2010 toyota prius, showing error code c1391. this caused reduced braking efficiency, and research shows it’s a common safety concern with priuses. while there was a recall, it has expired, leaving owners like me without support. i kindly request an investigation to address this critical issue for the safety of all affected drivers.

I was coming to an intersection where two cars were waiting for a right turn. i pressed on the brakes and nothing happened. the car continued to move without slowing down. the brakes felt "blocked" and unresponsive. i engaged the manual break at the last moment and that slowed me down. but i still hit the car in front of me which in turn hit another car in front of it. the police report says "following too close". but i was not following other cars. the two cars were already at the intersection. i was just coming to this intersection and attempted to slow down as usual. except that the brakes did not respond. my car was a total loss.

Twice while i was driving on the highway, my abs and brake light came on, and my brakes became less sensitive to pressure. that is to say, it took more effort and i had to push my brakes further towards the floor in order for them to respond. i went to an independent mechanic and got the code c1391 which indicates a brake pump accumulator issue. i went to a toyota dealership and and had the car inspected. they confirmed the c1391 code and said the brake booster assy with master cylinder pump assy was malfunctioning. however, i was never told by toyota that this issue meant my brakes could fail at any time. my safety and the safety of others was put at risk because my brakes spontaneously became less responsive, my stopping distance was increased, and they were at risk of spontaneous failure.

My car, a 2010 toyota prius, level v has about 161,000 miles on it, and i have driven about 140k of those miles over the last 13 years. i have traveled around the dc/maryland area and also taken the car on long trips. the car has been reliable, safe, and predictable... except in one place/instance. i have probably driven a dozen times or more to the bwi airport from my home in chevy chase. on the return drive on [xxx], as i drive towards an overpass that is just before the [xxx] exit, my prius goes into "emergency approaching collision" mode. the brakes automatically forcibly apply, the seatbelt/lap harness grab me, and there is an emergency beeping from the system. the first time this happened... probably 10 years ago, it was very startling. my car was traveling about 60-65 mph. luckily, there were no cars behind me... and i remained calm enough not to overreact. i was so startled that i needed to pull over to regain my composure. in one of the numerous other cases on this happening, my wife was in the car and she basically wanted me to sell the car because she felt it was unsafe. because i am aware of the situation with my car, i always am cautious when i am driving towards the [xxx] exit. i drive slower, watch carefully for surrounding vehicles beside or behind me. but even yesterday, i was driving very slowly (approximately 35 mph). while i did not feel the system take aggressive avoidance/safety actions, still the warning beeps did take place... a little unnerving, but i had come to expect a problem at that site. in any event, i did want to bring the matter to your agency. sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

Abs pump/motor failed. lost power and control over the breaks . abs light on

Break booster fail. will cause the breaks to fail. there was a voluntary recall on these but i never recieveed the letter in the mail. thr break booster failed after the voluntary recall was up. toyota said they cannot help with this. other prius owners i talked to have the same issue with their 2010 prius break boosters and also did not get the letter in the mail.

Abs lights on, traction light on .actuator running cicle constantly . breaks felt spongy

I own a 2010 toyota prius hybrid 4 door sedan. i am the second owner of the vehicle. i purchased it in 2018 from a used car dealer. the vehicle ran well up until 2022 where a “check hybrid warning would appear on the dashboard along with a yellow triangle and service engine light would come on and the vehicle accelerator would not respond and the car would have to glide to the side of the parkway. this problem would happen when the car speed is between 60-70mph. it is very dangerous to lose power on the highway because many times there is no where to pull over. in 2024 i changed the water pump because the fault code on the cars built in diagnostic code read error “p216b” which is the cars electrical water pump signal. i researched it on google and a lot of 2010 prius owners are complaining of the same thing. also the changed water pump from april 2024 died again in january 2025. it is very scary that the cars accelerator pedal goes unresponsive and all the fault lights come on. my vehicle has 155,000 miles runs great and my family loves the 40mpg it gets. however, this stalling problem is being ignored by toyota and could lead to a fatal car accident if not recalled by the manufacturer. to conclude, i would like for your office to possibly conduct an investigation with the 2010 toyota prius hybrid for this ongoing problem that the company is ignoring. this is a serious issue and can possibly lead to a fatal accident. thank you for hearing my complaint against toyota.

While driving at a high speed in the left lane of a 2 lane interstate a car in the right lane merged into me. luckily i was able to brake in time to avoid a collision, unfortunately the sudden braking at a high speed caused my car to loose all control. upon braking my front tires lost all traction and shifted my car to the right, i remained horizontal sliding across the highway for an unrecognized distance (my guess is 10-20 meters), before shifting another 90 degrees to the right leaving me backwards. at this point i had shifted across both lanes and the emergency lane, i was backwards in a grass border on the right side of the interstate. if this had been any other sort of barrier i may not have lived. this incident has not been reproduced or confirmed by a dealer or independent service center. the vehicle had recently had its worn brake components replaced in response to a similar incident happening, which i first attributed to worn brakes— this theory was supported by the brake technician prior to service. i have had a tire pressure light on since i purchased the car, but this was explained to me as a malfunctioned tps.

Brake booster, brake accuater went out even after the recall. dealership said they could do nothing to help

I drove the car to my destination without any issues. an hour later, when i restarted the vehicle to leave, the following dashboard lights were on (slip indicator, abs warning light, and brake system warning light). when i drove the vehicle, the brakes had diminished stopping power. it took farther for the vehicle to come to a full stop when applying the brakes. when we had it checked by the toyota dealer we were informed that there was an abnormal leak in the accumulator assembly (system diagnostic code c1391) and it would need brake booster/master cylinder assembly with accumulator pump replacement.

Odometer error

I am writing to express my concern regarding an issue with the pcs system dash lights on my 2010 toyota prius. i recently became aware of problems related to the brake booster system, which i understand have been addressed through recalls or warranty extensions on certain models. i believe that the issue i am experiencing should be covered under warranty, and i kindly request your assistance in resolving this matter.

- brake system failure - safety risk due to longer stopping distance - problem was reproduced and confirmed by two repair shops - components were inspected by repair shop - several brake warning lights were on on dashboard after failure occurred. toyota recalled 2010 prius vehicles for brake booster and brake booster pump assembly failures. recall code d0h. toyota claims that the replacement parts are fixed for the gasket leak issue. toyota replaced these parts on my car in 2013 as part of the recall. the replaced parts labeling are verified to be the claimed fixed ones. but only about 62,000 miles after the d0h repairs (odometer at 81,400 miles) the parts failed again on march 20, 2015. i do not put many miles on my cars. toyota has put a maximum repair date for this issue knowing failures keep re-occurring (no repairs supported after 2019). toyota has not fixed this issue given the repeat failures. repairs for this issue is extremely expensive at more than $4000 at independent shop (parts and labor)

Abs, traction, and brake warning lights came on. no obd code reading. mechanic says needs brake booster pump; brake booster master cylinder. theoretically mine were serviced but no way for me to actually verify it happened on the recall. vehicle located in kamuela, hawaii.

My abs system light is on. the toyota mechanic has determined that it is due to nitrogen gas from a component of the brake booster pump assembly could leak into the brake fluid. as nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. under certain circumstances, this condition could affect stopping distance and increase the risk of a crash. toyota recalled model year 2010 prius vehicles manufactured march 31, 2009, through october 9, 2009. i took my prius to toyota to fix this abs recall problems but they are refusing to fix the problem for free. they are charging me $4000 to fix it.

Narrative description. not a failure but a safety prevention measure 2010 toyota prius 1. event: when backing up the vehicle runs on battery power-hence it is silent when backing up. the vehicle in busy parking lots (walmart) goes unnoticed. 2. failure: i have surprised people who are distracted and don't notice me until they nearly walk into the side of the vehicle. they don't hear the car. 3. failure correction: a back-up warning device should be installed to alert pedestrians (blind folks, neighborhood kids, pets, etc) of a silent, backward moving vehicle approaching. there is several blind spots inherent to the prius when backing. helping others to notice you seems like "an ounce of protection that is a pound of cure" that is measured in a saved life or crippling injury. *tr

Regenerative brakes stopped working while driving in clear conditions on the highway at 60mph, abs, traction control, and brakes lights on dash illuminated. almost crashed as brake pedal needed to be pressed really hard and almost to the floor to stop the car. known issue and dealer refuses to fix the problem

I was driving and three lights came out: abs, brake and slip indicator.

I was making a left turn, creeping into a parking space, in a residential area. when i pressed the brake pedal to stop the car, the car accelerated instead. i then slammed on the brakes and the car accelerated again, causing me to go over the curb, over the sidewalk and knock down a fence and shed. i turned the vehicle off, some kind bystanders took the debris off the car so that i could get out. i then called police and the property owner, as well as my insurance company. i am honestly scared to drive the car again, as i do not want this unintended acceleration to happen again. i will be notifying toyota, and the repair shop working on my car has already been informed.

I was just told that my 2010 prius needs the brake boost assembly (cylinder and boost) at a cost of $2,570. it was causing my 4 month old, 12v battery to drain. i thought that was outrageous so i looked into it and found out there was an "enhanced extended" warranty issued (not a recall) , but for my vehicle it expired april 2020. another issue that i uncovered that this part also causes the prius to lurch forward when braking and you happen to drive over a bump. train tracks, or potholes which is a safety issue. i have also experienced this with my prius. fortunately, i have had no accidents so far. i have read that there have been accidents caused by this issue. toyota should step up and fix the problem before people are injured due to this defective braking system. my daughter drives a 2015 prius. is anything more being done? or are they going to wait until more accidents happen? i stumbled across this issue when my 2010 toyota prius 12v battery required frequent jump starts. i replaced the battery ($300) dec 2020. prior to that, i called aaa and got a jump start. because of covid, i wasn't driving the vehicle daily (work from home) so it was assumed the cause was the vehicle should be driven frequently.

I bought this car brand new in 2010. toyota prius hybrid. two weeks ago the abs light, emergency brake light, and traction control lights all came on and won't go off. dealership says i need $2000 worth of work. brake booster/master cylinder, brake booster pump assembly, brake actuator internal leak. brakes acting weird. dealership says i don't need to drive car, just pay $2000 which i don't have. they said toyota extended the warranty to december 2020, which just past. i never got letter saying it was a problem.

Tl* the contact owns a 2010 toyota prius. the contact stated while the vehicle was parked in her driveway, the vehicle independently rolled backwards out of the driveway. as a result, the rear end of the vehicle ran into a tree. the air bags failed to deploy. a police report was not filed.there were no injuries sustained. the vehicle was able to drive and was taken to a collision center. the vehicle was not diagnosed or repaired as of yet. a dealer was not contacted. the manufacturer had not been informed of failure. the failure mileage was 173,991. the vin was not available.

I was driving and pressed the brake pedal to make a turn. after completing the turn i noticed several warning lights illuminated on the dash board including brake, abs, and traction control. the brakes were very mushy but worked enough to get the vehicle to a shop. the shop assessed the vehicle which displayed code c1391 and said it was brake related possibly abs system. they cleared the code in my vehicle and brakes worked normal for a very short time before the same warning lights appeared and brakes went mushy and not working properly. i then looked up possible recalls or enhanced warranties and i called toyota customer service and was told there is no recall or extended/enhanced warranty for any braking issue on my vehicle based on the vin number. i took the vehicle to my local toyota dealer and they charged me to test for a code. they came up with code c1391 and state in their paperwork that the cause is "brake booster internal failure" and recommend replacing the brake booster. their paperwork shows replacement of a brake pump and brake booster had an extended warranty but that it expired 9/26/2020. therefore the dealer would not fix my car at the cost of toyota. my vehicle has approximately 91,000 miles and others with higher mileage have documented that toyota has repaired this known, well documented, expensive (about $4,000) and continued dangerous braking problem in several cases. per the dealership and my contact with toyota they are not willing to repair my vehicle at their cost., which at the toyota dealership is about $4,000 parts and labor. an additional issue is trusting toyota service and/or private mechanics that they will replace the problem part(s) or replacing additional parts making the repair bill higher or maybe not fixing the problem where additional repairs will be required before too long.

Tl* the contact owns a 2010 toyota prius. the contact stated while driving 20 mph, the brake pedal was depressed to the floorboard while attempting to stop the vehicle. there was an abnormal sound coming from the vehicle. there was no warning light illuminated. the vehicle was taken to toyota of tampa bay (1101 e fletcher ave, tampa, fl 33612: (813) 402-1323) on several occasions to be diagnosed. the contact was informed that the abs module needed to be replaced. the vehicle was not yet repaired. the manufacturer was informed of the failure. the failure mileage was approximately 152,000.

Traveling home from tampa to st. petersburg on interstate at 70 mph and suddenly breaks fail. brake, abs, and traction lights come on. pushed pedal to the floor and was able to get enough braking to pull off the interstate and into a gas station and into a parking spot safely. no warning-just immediate failure. miracle no one killed. reading many other similar stories for year. what is going on that this has not been recalled????

I inherited a 2010 toyota prius 3rd generation when my mother passed a few years ago. i've since had several unnecessary and costly problems with the car as well as dealership's outlook, treatment, and indifference to the danger that their customers face--as many already have. the following are situations that i'm experiencing now. first, i was recently leaving the pharmacy when all of my warning lights (abs, brake, traction ) suddenly came on and my brakes failed as i was heading home. i'm a single mother of a special needs child and i had to get home to her. i was approximately 1 mile from my home and i was nearly in 3 accidents that could've been catastrophic. thankfully the road was dry, clear, and with little traffic. we have been homebound for weeks, without transportation for doctors, food, etc. our vehicle is our only means of transportation, and we must get to doctor appointments, etc. second, the car has inexplicably stalled twice. third, i'm constantly having to replace lights, and have been pulled over by the police for lights not working. finally, an airbag has been recalled and once i can afford it i'll get that fixed as well. i spoke with my local toyota dealerships, and after explaining the problems, i was informed (several times as i was repeatedly transferred) that i had to pay an inspection fee that also changed with each person. finally, i was told i had to leave my car there for days and that i was going to pay thousands of dollars to fix the car. i'm unable to pay that much money--and the amount kept changing as well. i have researched these problems and now understand the methodology and intimidation used on poor people such as myself. toyota should be ashamed. fix these problems that will endanger and possibly kill your customers for nothing more than their own incompetence and greed.

Just purchase the car and they r refusing to fix the abs known issue under that abs recall

My 2010 toyota prius has leather seats and the passenger side light is coming on. according to toyota recall there was a problem with the leather seats and calibration.the sensor on the passenger side is not communicating with the front airbag so when you sit down and buckle in it does not activate the front airbag. a seatbelt and airbag light is constantly on.

Toyota prius 2010 started experiencing braking issues in january 17, 2020. car was taken to the dealer three times with miss diagnosis. in march dealer diagnosed issue most likely a brake booster and pump assembly which was a known issue with 2010 prius. toyota identified the issue in a previous quality campaign but only repaired if brakes fully failed. brake failure is what it took to have your car repaired?

I have lost all regenerative braking. the abs, traction control, and service lights are all illuminated continually. it has become difficult to stop and the hybrid battery is depleting at a rapid rate with very slow recharging.

On tuesday, february 23, our braking system failed on our toyota prius while driving on a side road after months of continuing weakness in the brake pedal and "lurching" when braking over potholes. the brake system lost hydraulic pressure. upon inspection by an ase-certifie mechanic, they determined the brake booster assembly had likely failed, but recommended sending to a toyota dealership. they confirmed the vehicle was unfit to drive. the vehicle was sent to a toyota dealer. the dealer confirmed the break booster assembly/actuator had failed. the dealer advised the brake booster had previously been under a toyota "customer service campaign," but that the "warranty" campaign had expired. however, he advised toyota brand engagement center has often assisted customers when they're just outside the warranty period. when contacting toyota, they stated this vehicle was never under recall and was not eligible, but then said they sent information on a toyota safety campaign. upon research, we continued to confirm that the diagnosis was tied to recall d0h from july 2013. we've also reviewed our vehicle history, and the brake pump assembly was never replaced despite being inspected consistently by toyota dealers since 2013 and under recall. toyota has declined to cover the cost of the replacement for the brake pump assembly. the cost of repair is nearly the same as the current value of the vehicle. toyota brand engagement center has declined to provide this information in writing, would not provide a name, and otherwise acted completely sketchy - for lack of a better word - any time we tried to clarify the repair was clearly tied to the june 2013 recall. we were very, very fortunate the brakes failed on a side street near our home, not on a highway or other high-risk area. we would like toyota to honor the recall, extend it for other customers, and cover the cost of repair.

Abs, traction, and brake light stay on. it is the actuator brake and the cost to fix is over $2000. i have researched this issue with other 2010 prius' and it is a common issue. this is a defect that toyota refuses to fix even though it is very common and puts many people at risk.

Tl* the contact owns a 2010 toyota prius. the contact stated while driving 20 mph and depressing the brake pedal to attempt to stop the vehicle, the vehicle proceeded to roll forward while the pedal was still depressed. the contact stated that the traction control warning light was illuminated. the vehicle was taken to an independent mechanic where it was not diagnosed. the vehicle was not repaired. the manufacturer was informed of the failure and informed the contact that the vehicle was out of warranty. the failure mileage was approximately 209,000.

Excessive oil consumption. this problem is identical to the hundreds i have read on the exact same vehicle. it is already well documented by owners.

My 2010 toyota prius began having chronic problems with exterior light going out, starting in may 2016 and persisting until now (november 2016). we have replace the bulbs repeatedly just to have them go out again. i consider this a very dangerous problem, and makes this vehicle unreliable. dealership denies a system failure and suggests to replace bulbs with expensive ones. this does not remedy the pr oblem.

On september 10, 2016, while we are driving back to indianapolis from chicago, the left dash screen became dysfunctional and went completely blank. there is no indication of the speed, the amount of gas in the tank, and the condition of the engine. we did not feel safe at all on the way home.on september 13, 2016, we took our vehicle to butler toyota where we purchased it for a checkup. after the diagnostic, the service department advised me that the combination meter was out completely. this combination meter must be replaced to restore the reading on the dash board. they told me that this unit is not under warranty, and i must pay $1,698.42 (tax not included) for this replacement (see attached). this combination meter is a critical safety tool to monitor the driving mechanisms, the condition of vehicle, and when the driver should refill their fuel tank. to resolve the problem, i would appreciate your consideration of this work as a faulty product and should be replaced without cost to the customer. enclosed is a copy of service from butler toyota.

2010 prius excessive oil consumption. using 5 quarts between oil changes is not normal!

Tl* takata recall. the contact owns a 2010 toyota prius. the contact received notification of nhtsa campaign number: 16v487000 (air bags); however, the part to do the repair was unavailable. the contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. the manufacturer was made aware of the issue. the contact had not experienced a failure. parts distribution disconnect.

On feb 19, 2016 i was driving my 2010 prius. the sunroof exploded, without being hit by anything. it exploded upward. i called toyota, but they said it was not their fault. i had to replace the glass. i have photographs.

My low beam headlights became noticeably more dim -- dangerously so as i began to need to use high beams to see anything beyond 30' in front of me. this began in 2012. then my low beam lights began to go out -- one side, then the other. we replaced them ourselves with high quality replacements (after we found out it would cost over $200 for labor and headlamp at our dealer). we were told by the dealer that the problem was only ours -- they had "never heard of it before." over the past three years, we have replaced 6 headlamps! today was the 6th replacement and we had it done at the dealers where we were told, again, that this is a problem that they have never heard of before. several times, i have had to drive home from work at night in the dark with no low beams (both went out) and use my high beams while cars heading toward me flashed their lights because of the blinding effect of using highbeams. please help!!

Tire light keeps coming on. third time. there is no problem with my tires. started this summer and continues today. i am taking my vehicle into a toyota dealer for the second time for this problem.

I went to start the prius after work, after i pressed the start button, several alarms went off on the main panel. alarms included the master alarm, abs, brake, check engine, and an incessant beeping. there was also a repetitive sound coming from under the hood that sounded like the braking system was trying to build pressure, but was not successful. i towed the vehicle to the dealership and they diagnosed this as the master brake booster assembly. the quote was $2500 for the part, and $500 in labor. they started work on the vehicle, then called and said that they would have to replace the accumulator as well, even though it was already replaced during the original recall. they contacted toyota corporate who paid for the accumulator, but would not cover the additional labor to install the accumulator. the total bill was $3900. this seems like a common problem with the prius family. my car had approximately 92,000 miles.

Excessive oil consumption. the car is consuming 1 quart of oil every 1,200 miles and has failed an oil consumption test performed by the dealer.

While driving in boston, i attempted to beep the horn to warn a car that was cutting in front of me, but the horn did not work. toyota diagnosed this as a bad clock spring in the steering wheel. the inability to use the horn is a safety issue. an online search seems to reveal that this is a common problem with multiple toyota models.

The low beam head lights constantly burn out. my car is at 108,500 miles, and i have replaced the low beam bulbs at least 5 times in the last 3 years. i have had this occur while driving on the interstate 5. another driver on the highway flashed lights at me, pulled up next to me, to indicate that my lights were out. i had to drive with the high beams on for over 20 miles. it was a very dangerous situation, because it was blinding to other drivers. however, if i had not done this, i would have been driving with no lights at all. this has happened to me three times after replacing the bulbs, which will last for a while ,but quickly stop working. i have owned several cars and have never had to replace the headlights even once.

Recall notice june 28, 2016, it is now sept 25, 2016, no remedy available yet

Tl* takata recall. the contact owns a 2010 toyota prius. the contact received notification of nhtsa campaign number: 16v487000 (air bags). the part to do the repair was not available. the contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. the manufacturer was made aware of the issue. the contact had not experienced a failure. vin tool confirms parts not available.

In july, i was braking to a stop on a suburban street but my brakes wouldn't allow me to come to a complete stop in time. it was raining. i finally came to a stop in the middle of the intersection, where i was hit on the drivers side by an oncoming car. additionally, my side airbag (curtain) didn't deploy. i was traveling less than 15 mph at the time.

Vehicle was parked. when i returned to the vehicle, the rear window glass had spontaneously shattered/ exploded. there were no signs of vandalism. i understand that this is a problem with the type of glass that is used, and that this is not an uncommon occurrence. examples may be found on youtube.

Tl* the contact owns a 2010 toyota prius. the contact stated that the vehicle was burning oil excessively and the service vehicle warning indicator was illuminated. there was also an abnormal rattling noise when idling. the vehicle was taken to labadie toyota (located at 909 n euclid ave bay city, mi 48706) where it was diagnosed that the piston rings needed to be replaced. the vehicle was not repaired. the manufacturer was notified and opened case number: 1707100976, but did not offer assistance. the failure mileage was 296,000.

The middle at times and the seat belt directly behind the driver do no stay in and lock. i have taken it back up to carmax where i purchased it and the guy said, "oh the kids had some candy in it" hahahahaha no sir thats where my elderly mother sits when i drive here around town to do her shopping. i was very unimpressed that they didnt fix such a huge safety issue. please help!

I was driving on the freeway. all of a sudden brake, abs and suction traction light turned on. after that i have to push my brake harder to slow down the vehicle. i was able to drive it back home safely. i took it to the dealer who said i need to replace brake master cylinder with brake booster. doing research i found many owners of the same model car have same problem and some of the cars are recalled but not all. i believe most of 2010 toyota prius car have issues with brake system which is bad for our safety. it can cause serious harm for our safety. i request your good department to investigate the braking issues for 2010 toyota prius vehicle. as a good citizen of the country, i felt i need to discuss this issue with you.

Abs brake light stays on all time.rear wheel gets extremely hot,

The engine is now burning oil and must be replaced. toyota is quoting me over 3,000 in parts.

I repeatedly must replace my low head-beam lights in my 2010 prius. they have been going out at a rate of 2-4 times a year. i buy mid to high range quality bulbs and are very careful to keep the bulbs clean during installation. i notice there are many people with similar issues. how can we get this escalated to toyota!

Abs and break light lit while going 55 mph. lost antilock break feature. local port st lucie tire and break diagnosed bad master cylinder and nitrogen leak into break lines. found recall on similar 2010 prius' due to nitrogen leakage into break lines

I was driving on the freeway at about 70 mph when the "check hybrid system" light came on and the car lost all power and ability to accelerate. it completely began to descend in speed and within 2 minutes came to a complete shut down. i could have easily been rear ended had i not moved to the side of the freeway as quickly as i did.

*takata recall i was involved in a major car accident during lunch hour on the 405 south fwy in los angeles, ca. i was struck by a semi truck who was merging into my lane and while i tried to get out of his way by speeding up. i was clipped by the truck and my car careened infront of the truck and was pushed before he applied his brakes. my car then spun out of control across all fwy lanes. i was hit by two other on coming cars before coming to a stop in the carpool lane. all cars including the truck were driving approximately 65-70 mph based on the police report. my foot was on the gas the entire time as i spun out of control. my complaint is regarding the airbags. none of the side or front airbags deployed at the time of all impacts. i had the vehicle inspected by an independant inspection company after contacting toyota. i have yet to hear back from toyota even though they have had the report for almost two months. i finally received the report from the inspector after threatning to have my attorney contact them. i don't know how to read the findings of the report since its all technical engineering. i am attaching the report and hope that someone in your department can review it and followup. thank you

The spiral cable assembly in the steering wheel has created a short circuit and now the horn no longer works. i am concerned this is a similar problem as other 2010 toyotas experienced and had this same part recalled in 2014 to ensure the airbag would go off appropriately if needed.

All brake lights come on (brake, abs and traction control) and power assist breaking stops working and brakes feel very weak. brake actuator runs frequently when lights are not on. there are many complaints online and toyota claimed they fixed this issue in 2009 and extended the warranty for 2009 and earlier, but the problem is clearly not fixed.

Rear windshield wiper motor would not turn off, even after the fuse was pulled. the dealer said it was a problem with the windshield wiper motor. this occurred when the car was turned on and stopped when the car was turned off. the normal wiper controls on the wiper column did not work. charge to replace it was $500.00

Tl* the contact owns a 2010 toyota prius. while the contact's wife was driving 35 mph, the abs, traction control, and brake warning indicators illuminated. the driver had to apply extra pressure to the brake pedal to slow down the vehicle. the vehicle was taken to an independent mechanic who diagnosed that the brake booster and master cylinder failed and needed to be replaced. the vehicle was repaired. the dealer was not contacted. the manufacturer was made aware of the failure and stated that the vehicle was not within the vin range. the approximate failure mileage was 95,000.

Abs light came on. diag code: c1391. abnormal leak in accumulator. this problem is similar to a recall on prius 2010 for abs brake issue. however, toyota said that my prius is not part of the recall. i would like to request toyota to fix this problem for my prius 2010 so that i can safely drive this car.

I change the brake booster twice and hace the same problem. my brake pedal loss of braking ability or slipping brakes and the warning brake, abs and traction light permanently on, and no cruise control works at all

Brakes turned to mush - pedal went all the way to the floor with almost zero stopping power. sounds like a similar recall from 2013 or so. going 45 mph (speed limit) on a busy 4 lane hghway approaching stoplight and slowing traffic for red light at intersection of another 4 lane road. brakes mostly unresponsive. almost went through intersection and narrowly missed hitting a slowing car. braking did not engage per usual activation position and pedal went to the floor instead. car was just serviced a week ago for unrelated recall item. car has been maintained diligently since new purchase in 2009, getting all recalls serviced promptly. maybe the range of vins in the older recall was not wide enough?

Tl* the contact owned a 2010 toyota prius. while driving approximately 30-40 mph, the contact crashed into the rear of a police vehicle. the air bags did not deploy. the contact's chest and face struck the steering wheel. the contact received injuries to the clavicle area, shoulders, face, eyes, head/brain, and neck area. extensive medical attention was needed. the vehicle was not towed; however, a police report was filed the vehicle was taken to the dealer where it was diagnosed that the air bag sensor was missed by a couple of millimeters, which prevented them from deploying. the vehicle was deemed totaled. the manufacturer was made aware of the failure. updated 07/13/17*lj *js

Tl* the contact owned a 2010 toyota prius. while parking the vehicle, it unexpectedly accelerated and struck another vehicle before crashing into an apartment unit. a police report was not filed and there were no injuries. the air bags did not deploy. the vehicle was towed to an independent mechanic, but the cause of the failure could not be determined. the manufacturer was called and provided the contact with an investigator who removed a box from the vehicle, which would determine if the failure was due to driver error or a safety defect. the manufacturer determined that it was driver error. the vehicle was not repaired. the failure mileage was approximately 53,000.

When driving over bumpy or rough surfaces or pot holes, while applying the brakes, the brakes often seem to stop working. and the car seems to have a little boost forward. it happens wherever the road surface has bumpy areas on straightaways or curves. and mostly when applying light pressure to the break, like slowing for an upcoming turn. it has been happening since i got the car in 2013. i have taken it to a mechanic, but they couldn't find the problem. this has happened many times over last 3 1/2 years.

Because of,as dealership said,the car was stalled at the highway. i don't have any sticker about recall, but most prius 2010 owners said that owners receiving notification about inverter problem. i'm heading to the dealership, who offered me to fix the car for $3,500. could you please take a look, do i have any warranty or recalls on this particular vehicle please. thank you.

I am the original owner of a 2010 prius. within the first month, i contacted toyota, complaining of the brakes, which were not consistently smooth. in general, the brakes work fine, but if i hit a bump or ditch, the brakes suddenly stop working for a split second, and the car feels like it is lurching forward, before the brakes suddenly start working again. toyota service was never able to "reproduce" the problem, and eventually i gave up. a couple years ago, the car was recalled for this problem, and i brought the car in to be fixed. unfortunately, the recall work has not remedied the problem. the brakes still seem to occasionally malfunction when the car drives over a rough patch. toyota seems to believe the problem has been solved, but it has not be solved. there is no difference since the recall.

Airbag warning light illuminates. toyota service techie's diagnostic showed a disconnected spiral cable. techie explained that the spiral cable has electrical connections to the driver's airbag module and the driver's air bag would not deploy in an accident. he said i should install a new cable spiral assembly kit (aka "clock spring"), part # 8430747020 at a cost of nearly $1000, including over $700 for the part. i did some research. part # 8430747020 was installed in many toyota vehicles, and has been recalled for the same problem in the corolla, matrix, highlander, tacoma, rav4, and yaris. see safety recall e0m (e1m) april 2015, update 5/12/14. the prius is not mentioned in the recall, although my car has the same exact problem with the identical part, and the toyota service supervisor agrees it is the same problem and part. i explained this to the service technician and supervisor, who called toyota, and toyota offered to cover 50% of the cost of the part, and none of the labor cost. i asked whether they could do the same fix in my car as they do on the recalled vehicles, namely installing part # 04004-07122, and they declined. see technical instructions for safety recall e0m spiral cable replacement. toyota should be recalling my car and fixing this problem at their expense, not just reducing the cost of the part. second, they should not be replacing this defective part with the same defective part. they should do a fix that will last. i assume the fix they've done on all other vehicles, with part # 04004-07122, would work for my prius. they refuse. fyi- the airbag light has been on and off for years, and seen by toyota during that period. this particular problem was diagnosed may 1, 2017. they believe the previous airbag warning lights were unrelated to this particular issue.

This car fire burned

Went to swap the license plate in my prius after registering in new state. back license plate bolt on upper-right side unscrewed partially and then the bolt housing detached from the vehicle. as a result, the screw cannot be unscrewed and the license plate cannot be removed. called toyota and they knew what i was talking about. said the repair would take one hour and cost $110—for a bolt that malfunctioned. the vehicle isn't technically street legal now and they can't see me for several days. i said that i didn't think a component like that should just break off, and i was told it may have been a result of the wrong bolt size being used. that's unlikely as this car has only ever seen toyota dealerships and that was where it was purchased. very disappointed and it sounds like toyota knows about this issue.

When i am coming to a stop (braking normally) and hit a bump, the car surges slightly and the brakes become less responsive. it feels like i'm fighting the engine as it accelerates and i'm trying to brake against it. releasing the brake and attempting again seems to be a solution, but i often don't have time before reaching the intersection i'm approaching. this consistently happens in two places in my daily commute with a slight buckle in the road approaching an intersection on city streets and county roads.

In fall of 2015 recall for hybrid system failure was preformed to computer system. in the fall of 2016 i was pulling out onto traffic onto a state route when engine lost power and lights for the hybrid system came on. was running on only gas engine with limited slow acceleration to about 35 mph. was able to safely drive it to a location to park it until flat towed to the dealership. was told by toyota dealership that the hybrid system failed, upon research i found it failed exactly as stated in the recall that was done in fall of 2015. the previous recall "fix" was too little too late the damage had already been done. fought with toyota dealership and corporate about that this was a recall fix that failed and didn't fix the problem. they would not cover the cost of the $3000 repair entirely and i am stuck paying half of the repair that should have been covered entirely under the recall.

This afternoon, my wife was driving down a two lane, paved street at about 25 mph. the street has a slight decline and she began to apply the breaks to slow down slightly. just a second or two later, she hit a small bump in the road and the car accelerated (while she had her foot on the break) for a fraction of a second. we didn't hear the sound of the engine revving. thankfully, there were no other cars on the road at this time and there was time to press the break again. based on looking around online, many people have reported similar issues (http://www.consumerreports.org/cro/news/2010/02/toyota-adds-2010-prius-braking-problem-to-the-list-recall-possible/index.htm).

Excessive oil consumption starting at 100,000 which worsened. i now have to put a quart of oil every 750-1000 miles in my 2010 prius. no one at toyota will admit this is a problem, albeit there are an extreme amount of these complaints online through different blogs and web sites. really, we toyota owners bought this car to decrease our carbon footprint...ironic, right?

My toyota prius is in good working order, as i just got it inspected for the ny state annual inspection on 3/23/2017. last night, 4/2/2017, i drove my car to a restaurant and parked it there. when i got back into my car to leave after my meal, i turned on the ignition and switched the headlights to turn on while the car was stationary and parked, but both appeared to have burned out suddenly. only the running lights switched on. to drive home, i had to use my high beams. i tried turning the car on and off, and switching the headlights on and off while the car was parked, idle and in motion to see if they'd turn back on, but they wouldn't. when i got home, i did some research and it seems that this is a long-standing problem for this model of car, as well as priuses made in the years prior. please see the below links: http://www.carcomplaints.com/toyota/prius/2010/recalls/ https://wheels.blogs.nytimes.com/2011/01/21/toyota-prius-headlight-failure-sparks-class-action-suit/?_r=0

In 2016 about the 130,000+ mile mark on my vehicle, i started complaining about my car consuming oil. the dealer findlay toyota assured me that it had to do with the heat and was normal. i was lead to believe the paper i signed after the work was complete has to do with the maintenance being done, no one mentioned it meant all my concerns were acknowledged. the days continued and even in during colder months of the year of 2016, i again notified the dealership of my car eating oil and it was nowhere to be found. again i complained and it was not annotated or written anywhere in their files. it was not until 26,000 miles plus more that they finally acknowledged my issue and took their time to search for the cause. in the month of march 2017, one individual from toyota actually took his time and did a full check, instead of the usual its hot here and that eats your oil excuse, he give me an answer which lead to me having concerns about toyota dealerships, he said the pistons had a leak and it was burning up my oil. i called toyota and found out my car had a recall for this issue but here is the catch, my car would have to be under 150,000 miles, which it was under when i started to first complain. now that i am over that mileage and was never notified, great dealerships tell you when you take your car for any maintenance about recalls, they say it sup to me to fix this issue they knew these cars have. since they never wrote down any of my complains, there is no proof of me complaining. this car burns oil moving or sitting as long as the pistons are moving. where has the honesty and professionalism of findlay toyota. what is my next step i ask the reader?

Car purchased new and serviced at toyota dealership every 10,000 miles using 0-20w synthetic oil. at around 106,000 miles i noticed the display flashing something but could not, at that time, read what the warning was. it seemed to happen going around curves, turning etc. finally, at maybe 107,000 miles, the warning stayed on long enough to see the low oil warning. took the car in at 108,000 (no oil on dipstick at that point) and the service department checked for leaks and found none. i was lightly admonished by service for driving without oil. fair enough, i thought at the time. i was slightly chagrined as i have always religiously had my oil changed (or changed it myself) on all my cars at the recommended intervals with no signs of a problem. the toyota service department recommended that i monitor oil usage. i did, and to my surprise 2,500 hundred miles later, i had to add a full quart. then 1950 miles later, another quart. yesterday, another quart at 1048 miles. very disappointed as the car has been without problems until now. have not discussed this with the dealership, but am not encouraged by the tenor of comments posted here regarding toyota stepping up and accepting responsibility. i see no need, at this point, to pay to have an oil consumption test done by the dealership as the car is obviously using an excessive amount of oil.

I've had two toyota prius in my lifetime, a 2005 and a 2010 toyota prius, both have had the same issue where the engine would eat up all of my oil, i would have an oil change done and less than 2 weeks later i would have to check the oil gauge rod and find that the oil levels were below the bottom line, almost empty! the engine would be burning oil at such an alarming rate that i would repeatedly bring the vehicle to toyota for oil changes. i'm very unsatisfied with my toyota priuses. my car is currently at 166,384 miles and the engine cylinder has now given way and also the hybrid battery. i've gone only to toyota dealerships to have pristine consecutive service and no third party repair facilities have provided service. i am located in souther california in san diego. i have spoken to many other toyota prius owners and if you do a google search online as of (04/10/17) "toyota prius engine oil consumption" you'll find many forums with "excessive consumption" from many other users. once you reach past the 140,000 mile mark, your car is pretty much done. consider buying a new one. toyota priuses and their engineers have to come up with a way to satisfy current and future prius owners as many of us will find that there will be many problems and issues down the road.

Driving down highway at posted speed limit (75mph), i tried to slow down due to traffic and noticed my cars ability to brake was severely compromised. i then noticed my cars brakes, abs, master warning and vsc lights had came on. given that my car has 103k miles on it, i figured it is time for a brake pad service. with the limited braking ability, i decided to make the short drive to the toyota dealer for brake service. after the dealer inspected my car, a representative told me that it is not the brake pads that are causing the lights in your dash to go on but rather the brake booster. they advised me that it is not recommended that i drive the car anymore until the issue is remedied by replacing the brake booster at a cost of over 2k. i had to also incur the cost of a rental since the booster was not in stock and would take over the weekend to receive. i was taken aback by the total cost of the service but had no choice and proceed to get it repaired. upon receiving my car a few days later, i drove to work and upon my return home, the issue repeated itself with all the lights on the dash lighting up and the cars braking ability was again compromised. extremely irate, i drove directly to the dealer and upon inspecting the car they told me that it is now the accumulator that needs to be replaced. this time the dealer absorbed the cost of over 3k to replace it. i researched the internet for any known recalls and found the issue was being addressed by toyota with a recall however my cars vin was not part of it. it is my hopes that you make toyota aware of the safety issue and initiate a recall on all 2010 prius models and not just some. i would also like to get the cost i incurred with this safety issue reimbursed at some point.

Both low beam headlights do not go on at all. were working properly on way to a destination at 9pm, then did not go on after car was parked after 2 hours. this has never occurred before. bulbs are not burned out, fuse is not blown. all other mechanisms on fuse working properly (backup lights, horn). parking lights and hi-beams work. very dangerous drive home, use of hi-beams on surface streets not safe for other drivers.

2010 toyota prius failed an oil engine consumption test at 98,000 miles. it burned 3 quarts in 1,100 miles. toyota has service bulletin issued in november 2016 to cover this car but inherently, it isn't covered. i have service records that this was happening in june 2015 at 82000 miles, before i bought the car in sept 2016. toyota will only cover half of $3000 cost of repair. issue appears to be widespread, across many models from what i've read online and experienced in the dealership. toyota's failure to address this situation when it has been happening for years is highly alarming, considering it affects a major part of the engine.

Tl* the contact owns a 2010 toyota prius. the contact stated that while driving at approximately 45 mph, the brakes operated independently while the contact was depressing the accelerator pedal. the vehicle was taken to jack taylor toyota on 3750 jefferson davis hwy, alexandria, va 22305 where the diagnosis was undetermined. the contact mentioned the pre collision system was deactivated however, the failure persisted. the manufacturer was notified of the failure. the approximate failure mileage was 95,250.

Tl* takata recall. the contact owns a 2010 toyota prius. the contact received notification of nhtsa campaign number: 16v487000 (air bags) however, the part needed for the repair was not available. the contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. the vehicle was taken to peoria toyota dealer, located in peoria, il, where the vehicle was rejected to be serviced due to the remedy part not available for the repair. the vehicle was not diagnosed or repaired. the manufacturer was not made aware of the issue. the contact had not experienced a failure. part distribution disconnect.

Srs light illuminated. toyota diagnostic completed at local toyota dealership. diagnostic indicated failure of spiral cable (clock spring)....similar to other toyota vehicles that are part of a recall. contacted toyota 1-800-331-4331. prius is not part of the recall, even though it seems that it has a similar failure. toyota logged the complaint.

The headlight burn out very frequently and most recently the shop informed me that the light does not stay in the assembly because the headlight assembly has melted. i am forced to drive without headlights and this is very unsafe. new headlight assemblies cost at a minimum of $100 each and i am having problems shipping the items to guam where i reside.

Headlights burn out often and are extremely dim making it impossible to see without using brights. lights are the same stationary as well as driving

Both front driver and passenger door motors have went out. thus happened last year and after further reading it is a common problem with all them. we only have 65,000 miles on this car.

Traveling straight forward at 40 mph and approaching a red light. immediately upon depressing the brake pedal, an alarm sounded and the abs, brake, and traction control warning lamps lit up on the dashboard, and my prius completely failed to brake, continuing unabated toward the other vehicles stopped at the red light. i began pumping the brakes and was able to build up pressure and safely stop without collision or further incident. my local toyota dealer diagnosed the problem as a "brake accumulator internal leak. recommend replace brake accumulator". this needs to be recalled, this is egregiously irresponsible by toyota, i easily could have been hurt or killed.

Tl* the contact owns a 2010 toyota prius. the contact stated that the vehicle's low beam headlights would fail approximately every two months. the contact had to replace the low beam lights approximately 20 times since 2010. the contact called the jeyes toyota dealer where it was diagnosed that the vehicle's low beam head lamps failed and the low beam lighting harness needed to be replaced. the vehicle was not repaired. the manufacturer was not made aware of the failure. the approximate failure mileage was 150,000.

Oil consumption. i purchased my prius with 77000 miles for a local toyota dealership. my car now has 140000 miles and consumes 2-3 quarts of oil per week. i have contacted toyota customer service for help. i was directed to have an oil consumption test preformed. if there is a problem toyota may offer repair assistance however my engine is not on the list of toyota approved vehicles eligible for complementary repair. i am required to pay out of pocket for the test and repairs. i will update with results as soon as possible.

Tl* the contact owns a 2010 toyota prius. while driving approximately 50 mph, the vehicle lost power without warning. the vehicle was towed to the dealer where it was diagnosed that the electrical system fried the inverter and shut down the entire system. the contact stated that the software was an ongoing issue and overheated the inverter, which caused the engine to shut off and the vehicle to completely stop. the vehicle was repaired. the manufacturer was notified. the approximate failure mileage was 65,000. updated 01/04/17*lj the consumer requested a response and/or status report. updated 7/7/17*js *tr

Brake system failure while driving on suburban street. master cylinder, assembly and booster replacement. all corresponding warning came on. was able to drive to dealer. this is the exact problem that incited the recall for nitrogen leaking into the brake system in some prius made in 2010 (82,000). cost of $3200. incidentally, brake fluid was flushed and changed at 60,000 and then again at 75,000. the reason, stated from the dealer is that maintenance was responsible for the failure. priority toyota of springfield was the only one during the maintenance and i followed their recommended advice for the 2 brake fluid flushes and replacement.

Driver's side window shattered without being hit by anything. the shock of this happening, almost caused an accident while driving.

There is a recall notice we received about a risk of spontaneous activation of curtain airbags and the potential for passenger injury. however, for several months i have been contacting various dealers to request the remedy and they say toyota has filed to provide them with the parts to remedy the problem. it is very troubling to be aware of a recall while such delays occur in fixing it. obviously, if my family were to experience injury due to this delay, we would definitely hold the manufacturer responsible.

Intermittent failure of for door locking/unlocking mechanism. apparently a fairly common occurrence in this make and model. safety risk : inability to exit the vehicle in an emergency e.g. accident, fire, if the locks fail unexpectedly.

In feb 2015 after owning the car for a few months, the sunroof exploded on the freeway at a speed of 60 mph. the break was directed up to the outside (not down as if something struck the window). the side windows were cracked so it was not an issue of the heat/cold change or too much cabin pressure. now aug 2016, the exact same thing happened again. this time toyota is refusing to acknowledge there is an issue with the sunroof. in both instances, the sound was loud like a shotgun and extremely startling. glass could have rained down on me or i could have been startled causing an accident. i do not understand how the sunroof can break twice in the same manner within 1 1/2 yrs owning the car. this seems like a dangerous issue and am concerned that it will happen again. i have pictures but am unable to load them. i also have a video camera in my car to show that there were no other cars near me at the time this happened.

Three times in the past 12 months i have had my one or the other of my headlights dim and go out. the first time i replaced both headlights assuming the light needed to be replaced so i should just do both. it has occurred two additional times and finally, last night, i returned to my parked car to discover both headlights were out. i was forced to drive home switching between high beams and no lights. replacing bulbs every few months seems excessive. losing headlights in the dark is dangerous. this problem needs to be addressed by toyota and a recall needs to be initiated.

Last year (by a letter not dated !) toyota motor sales usa mailed us a safety recall notice "interim notice" regarding the curtain shield air bags and since then the toyota dealer did not contacted us to install the retention brackets designed to prevent the inflator chambers from entering the car interior. when will the remedy be available ? if it is available can we be contacted as soon as possible by the dealer (jim coleman toyota, 10400 auto park avenue. bethesda, md 20817). thank you *tr

All the lights on the dash associated with antilock brakes, traction control, brake are on. the braking has changed and does not slow the car as fast as it used to, almost hit the car in front the first time i drove it with the lights on that morning. car has 50,394 miles on it, noticed all the lights on when started car in morning, brakes appeared to work normally when backed out of driveway, but at higher speed stops the car travels a lot farther and takes a lot more effort to stop.

We came to the dealership at auburn blvd and they told us they don't have a parts for recal and it will take about a week to order them . they gave us a paper stating that the recal has been fixed for dmv purposes to renew the registration even though recal wasn't fixed. it has been more then 4 months and no one from dealership called us to inform us when they'll actually fix the recalled part. every time i call them they say they don't have part in stock and they don't know when they'll receive it. please help!

Oil warning system came on 4-20-16. oil change not due for another 1000 miles. garage changed oil at 95188 miles. less than 4 months later on aug. 9,2016, oil warning system came on. i watched as 3 quarts of oil were added at mileage 99712, 4524 miles later. prius is using 1 quart of oil for every 1500 miles.

Toyota has not remedied this known issue in a reasonable amount of time. i, the consumer, owner, and operator of the vehicle is continued at risk while and until toyota prepares the remedy parts. time to remedy is unannounced and vehicle operator feels at risk.

Driving on a extremely rough street, my car jerked to the left. i tried braking, but unmovable objects (street sign and phone junction box) provided the stop. airbags did not deploy, but force of car pushed me hard into the steering wheel. i had my safety belt on, plus back brace. emts noted 60% o2, in icu on respirator for a week, hospital for 2 wks. distinctly, i remember the steering wheel jerked to the left.

While accelerating on a highway going from the right lane to a left lane with my two young children in the car, i got a" check hybrid system" on the screen. which made the car unable to accelerate, all i could do was to put my hazards on and pull thru 3 lanes of high speed cars to get to a breakdown lane next to an on ramp, so i was in the middle of the 4 lane highway and 2 lane on ramp. i then got my kids out and ran across the on ramp to put them on the other side of the concrete barrier for protection. then i went back to the car to gather waters and food because it was 90 degrees out in utah, i waited on the side of the road for 30 minutes until a tow truck came. i am very very upset about this because it could've caused an accident and also put our lives at stake from possible re end.

Over the past three weeks i have noticed the check major system light flickering when turning to the left or right or coming to a sudden stop. i took my car in for the 80,000 mile check and told the service technician what i had seen. he told me he could tell me what the issue was without looking at the car. he said the car was burning excessive oil, the issue has been reported to toyota and he would file a case with them for me. he also told me the cost was about $3000 to fix the problem, that i may or may not hear back from toyota about this. when they finished servicing my car the technician told me they had added extra oil to top it off. this is the first toyota i have owned. i bought it new and have never had an issue with it. i have taken it in for every maintenance check. i was disappointed that toyota knows about this issue and has done nothing to notify owners of the issue.

Tl* the contact owns a 2010 toyota prius. the contact stated that the brake pedal required to be depressed several times in order for the vehicle to come to a stop. the abs, the traction control, and the brake warning indicators illuminated. the failure occurred intermittently. the vehicle was taken to a dealer where the failure could not be duplicated. the manufacturer was not notified of the failure. the failure mileage was approximately 159,000.

It has been two months past. the manufacture still didn't take any action. i can't sell my car now due to the recall!!!

Excess oil consumption at 93,000 miles. the toyota dealer has told me that it will cost $13,000 to replace the engine and that is my only option.

My low bean headlights keep burning out on my prius. i have replaced them with oem replacement bulbs and other high quality after market bulbs and no matter which one it is it continues to burn out. they continually burn out after very little use and in a very short time frame. i make sure i follow the recommended handling and installation procedures to ensure i don't compromise or wrongly install the bulbs. this is a major hazard while driving down the road. i never know when my headlights are going to fail. this has occurred at night and in weather where headlights were needed. this is a major safety hazard and from reading forums, this is a common problem with 2010 toyota prius. this is a safety issue that needs to be addressed by toyota.

Abs actuator with master cylinder assembly has internal leak. assembly doesn't hold pressure and actuator motor continiously working in order to create the pressure. due to this problem brakes are not operate as properly. it takes more strength to put on the pedal to stop vehicle. i also noticed that during emergency braking not all wheels were involved equally. due to this problem braking distance significantly increased. i have 3 instrument cluster error lights turned on due to this problem: "brake", light with vehicle on sleepy road, and light with "!" sign. i found that there already was recall for same 2010 year toyota prius under tms-ntc-13178 of july 23, 2013, toyota recall name d0h, but my vehicle is not covered. i kindly ask you to investigate if my car eligible to participate in this recall campaign, since seemsthat this car were assembled with same unreliable parts.

A warning light came on for eps and 30 seconds later it stalled and would not steer or move. i was driving at 6pm on a friday in major traffic

On picking up my prius after routine maintenance, i was told that it was 3 quarts low in engine oil. i was stunned as i had had no warning of low oil pressure or loss of performance. the dealer is conducting an "oil consumption test" to measure how much oil will be consumed in 1200 miles. the estimated repair cost was $2000, but my husband who is very knowledgeable about engines doesn't believe the suggested repair will fix the problem. i have only recently become aware that this is a prevalent problem with late model toyotas, not just prius. the customer service agent and the service tech we spoke with were cagey when asked how frequently they have seen this problem. i believe toyota is very aware of the issue, but are willfully not addressing a remedy.

The brake actuator failed on our 2010 prius iii manufactured in october 2010. toyota is covering problems with this same brake actuator for 2010 prius manufactured between march 2009 and early october 2009. my vin did not fall into that date range even though mine was manufactured in october 2009, so the brake defect should be extended to beyond the early october 2009 manufactured date. the symptoms to this problem were the brake, abs and traction control warning lights came on, no regenerative braking and the braking distance increased.

Speedometer and gas meter electronic display no longer works. it stopped once it was in motion and has not turned back on. took to dealership and it is not a fuse. entire digital display panel would have to be replaced. there was a recall for this exact issue up until the 2009 toyota prius models. car was reviewed at red mccombs toyota, san antonio tx i10-w.

The brake booster pump assembly failed, which left me with no brakes and in a life-threatening situation. the vehicle was in motion and i narrowly avoided a bad accident on a city street.

Headlights fail frequently. this happened over a period of 18 months. it began with a front driver-side headlight not working, then both headlights not working - each was replaced when noticed they were not working. the most recent time, 5 months after the last replacement, i noticed one headlight was out again, then, while in park, with the car still on, i turned the lights off then on again, and after that both headlights and one daytime running will not work. needless to say this is incredibly dangerous.

Abs + breaks + tcs lights are on and my car's breaks are not working it was about to hit with next car but my speed was under 30 that's why i reached safely. i showed it to just break and they said it's required ecu update. it's a software problem in this model. i don't know how to update software. is it possible if i get free update from toyota dealership ?

My low beam hi-intensity lights continue to burn out every six months or so. a single headlamp does not offer sufficient illumination of the roadway and i feel unsafe driving at highway speeds. the last time it burned out i was traveling down an interstate highway at 65 mph. *tr

I keep replacing the low beams. they do not last longer than 3 months before they burn out again. i'm buying high end replacement bulbs that should be lasting years. i've noticed that they burn out following my car pausing when i apply the gas from a stop but it only will go15-20 miles an hour then the car will surges forward and drives normal. help there is something not designed correctly! please have toyota fix this.

Earlier i reported that both headlights went out simultaneously. my mechanic replaced both headlights and they now work. 37 months ago the same thing happened. it seems highly unlikely that this is just a coincidence. fortunately the first time it happened i was close to home but this time i was not.

My 2010 toyota prius iv has 98,731 miles on it. the engine and power train malfunctioned during a cold start so i had to take it into the toyota dealer. it had to be towed to the dealership on a flat-bed tow truck because the car transaxle/transmission was locked in the drive position, would not go into neutral, and the car engine would not start rev above an idle. when i attempted to start it the engine acted like it was misfiring very badly and rattled very badly. it sounded like the engine was not getting any oil circulation so i didn’t attempt any more cold starts. i could not get the engine into neutral or any other gear so i had it towed to the dealership. when the car was at the dealership i went through my records and found a letter titled “warranty enhancement program notification - zf3” that i had received several years previous. the document extended my primary coverage until 31 march 2017 due to a potential faulty exhaust gas recirculation (egr) valve. “a faulty egr valve would cause the engine to rough idle/rattle from the transaxle at a cold start due to a sticking egr valve. if this occurs, the vehicle may illuminate the check engine light and set diagnostic trouble code dtc p0401. if the condition is verified the vehicle will be repaired in accordance with the applicable technical service bulletin under the terms of this warranty enhancement program.” the symptoms my car experience during cold starts begin around 92,000 miles but no “check engine light” or “diagnostic trouble code” ever illuminated on the instrument panel. after 92,000 miles it only happened occasionally, and always during cold starts. normally after a few seconds of idling the rattling would go away and the engine and drivetrain would perform as it should. i took my car in for a service and told the dealership what was happening, but they could not diagnose any problem.

On jan 24, 2017 while driving this car at night both headlights turned off. when i turned the knob to turn the lights back on only the parking lights came on. the car was in motion on a city street when this happened. *tr

Vehicle after awhile starts to consume oil. it’s runs out of oil very quickly. there is no oil leak.

Went over bump at railroad crossing and abs, brake, slip warning lights came on and regenerative braking stopped working. car was harder to stop. took to dealer and car was diagnosed with this work needed: replace booster and booster pump assy and reflash (failed booster, booster pump) fail $3,259.84 car is beyond warranty fix dates though all these cars were recalled in canada and a class action suit is ongoing in ohio over this issue. why won't the ntsb follow canada's lead and get these failing brake systems fixed before something serious happens?

Tl* the contact owns a 2010 toyota prius. the contact stated that driving at 15 mph, the brakes failed to operate as needed upon depression of the brake pedal. the contact stated that several warning lights appeared on the instrument panel including the abs, tire pressure, traction control and emergency brake lights. the contact was able to drive the vehicle to haley toyota of roanoke (1530 courtland rd ne, roanoke, va 24012) where she was informed that there was a crack in the brake booster pump assembly accumulator, a decrease in the hydraulic pressure, and a defective brake master cylinder. upon investigation, the contact linked the failure to nhtsa campaign number: 13v235000 (service brakes) however, the vin was not included. the manufacturer was not notified of the failure. the vehicle was not repaired. the failure mileage was approximately 162,000.

I was driving down the highway and the traction control, abs, and brake light all come on. i go to use the brakes and the pedal was a lot firmer and was harder to press. the car makes a buzzing noise i believe it is the brake accumulator. i go to the nearest place to get the codes read. it came up with c1391 and i look that code up and it comes up with that code is a common issue with the prius. i read that it could lead to brake failure.

The casing of the brake actuator is cracking. the brake actuator apparently is an underlying problem that toyota does not want to take responsibility for and fix.

My car's abs, traction, and brake lights are on. i took it to two shops and they both said my car was recalled and to have the dealership fix it. the recall is on the breaks. the brake pedal is also not fully working, there is an abnormal leak of brake fluid pressure. both auto service places said to demand for the dealership to take car of this because there is a class action lawsuit going on for this car with this exact problem.

Toyota brake booster pump has failed due to manufacturing defects, which affected the stopping of the vehicle. toyota has issued recall for this problem but only for latest models (2019 and later). i've called to toyota and they refused to address this problem. i looked up on internet and found this is a wide spread problem experienced by many owners of priuses. toyota must issue the recall for all the vehicles affected, not the latest ones only.

I was driving on the hwy with 3 children when it cut off on me and my steering wheel was locked . i took it to four mechanics i saw the toyota dealer and they told me that it was my battery and now i know that i have a recall on it . i have not driven my car in three months i’m also still paying payments on it . i also was told that it was my break. i bought a new brake booster and pay for the replacement and the problem was still hungry just

Headlight bulbs keep going blowing consistently.vehicle stationary

I travel to work one hour away from home, on high speed highway's my break system lights turned on, traction, abs and break, break pedal sinks and will not break and is very dangerous when driving home. i hope no one gets killed

I am having an issue with my brake actuator/brake booster. this is a known issue and toyota is refusing to help with the issue. the abs, brake, and traction control light are on and regen braking is not working. they are supposed to cover this based on bulletin zjb but absolutely refuse any help.

Was going 25 mph yesterday november 22, 2020 evening when 4 (brake, abs, traction & caution) lights came on dashboard. pulled over the shoulder & turned ignition off. restarted later & 4 lights still on. following day, went to dealership & was told brake booster assembly need to be replaced due to internal fluid leak.

Excessive oil consumption after having my oil changed at the dealership at 100k miles, i left on a cross-country trip. during the trip, the low oil pressure signal flashed on my dashboard. upon pulling over and checking the oil, i found there was no oil in the engine at all. i added 4 quarts checking the level in increments with the dipstick, and continued. i had to add an additional quart of oil to the engine over the following week, until returning home. upon returning, the dealership refused to accept any responsibility for the issue and informed me that i needed new pistons and rings. they did not inform me that this is a recurring issue with my generation of prius and were quite firm that it was not their problem. there is not reason that a toyota with 100,000 mile on it should randomly start burning excessive amounts of oil within a few thousand miles of an oil and filter change. all of the maintenance is performed at the dealership at the specified intervals, and i would expect that toyota would stand behind a toyota that is maintained per toyota specifications. *tr

I got in my prius about a month ago and turned the headlight switch on, and neitherof my low beam headlights worked. i thought it seemed odd that both lights went out at the same time. i purchased the most expensive bulbs at my local auto parts store and replace the bulbs. they worked great until about an hour ago. i started my car and when i turned the head lights on, both of them came on for a fraction of a second and then immediately went out. i had to drive home with my bright lights on.i started reading prius forums and came to realize that hundreds of people with the same prius model and year were having the same exact symptoms in their cars. there's obviously an electrical problem with the 2010 prius. it's time to issue a recall. now i'm going to have to by another set of bulbs which will cost me another $60. please help us. it's unfair that 100's of us have to suffer from such a flaw. thanks *tr

Excessive use of oil began at 80,000 miles. dealership said that it was normal for my model and if i kept an eye on it and kept oil in it everything would be ok. i do not get a warning light. one time i had to put over 3 quarts into it--no warning. i now check it every 800 miles and must put a quart of oil in about every 1000 miles.

I applied brake on a red light which is as usual for me and i noticed car didn't slow down and kept moving past the red light. it has happened before and the it happens on uneven and even on minor potholes. the brakes on the small bumps and minor uneven roads completely loose traction of the tires and car even faster with the brakes on when trying to stop over minor uneven roads. mechanic said it's oversensitive anti locking brakes that cut off the brake power even when it detects minor disturbance in the sensors. *tr

I have a 2010 toyota prius. when trying to slow down, any time a bump is hit, (or a pothole) the braking power significant decreases . this greatly increases the stopping distance and is very scary in traffic and in winter driving. is this a problem? i called toyota earlier for the same issue and they told me that this is normal and this occurs because only one tire is hitting the pothole or bump… it is very scary and i have to leave a lot of space ahead of my car.

My wife was driving on the highway when her brakes totally failed. she applied brake pressure as hard as she could, but it had not effect. fortunately, since she was in the left lane of the interstate highway, she was able to coast to a stop in the left hand shoulder. several red lights lit up on the dashboard, including the brake and abs lights. i had the car towed to world toyota dealership in atlanta. they said the brake master cylinder failed. i paid them to fix it. see attached work order from world toyota. *tr

After providing notice of nhtsa recall no. 16v-487 toyota subsequently refused to replace the retention brackets on the curtain shield air bag inflators subjecte to said recall. the recall is clear that the retention brackets should be provided at no charge.

I've had to replace my low beam head lamps 4 times in the past 6 months. first i was on a 2 hour long trip when my passenger and i could specifically see both headlights were getting dim. after about an hour of driving they had both gone out completely and i was forced to use my high beams on the interstate. when we arrived in town, both bulbs were replaced and the driver's side bulb lasted 3 months before dying out. i rode around like that for a week because i kept forgetting until i'd drive at night and the shops were closed. so about a week after my driver's side bulb died, i went to the auto store and bought a new bulb, only to find out my passenger side bulb had gone out that same day; i didn't notice because it was during the day. thankfully i was already at the auto shop and was able to have two new bulbs installed at the same time. well...with my brand new bulbs i was confident that it was going to be fine this go-around and they were bright for a couple months. until my driver's side bulb went out unexpectedly when i was parked in my driveway. i was getting ready to leave and saw the reflection on my neighbor's window -- no more driver's side light. i put my plans on hold until i went to the auto shop and they replaced the bulb no problem. four days later, the passenger side bulb goes out. i'm fed up with having to get new bulbs every few months (or days for that matter). it's occurred when i was parked, driving slow in the city, and going fast on the interstate. it doesn't matter the state in which the vehicle was being handled. the lights are going out consistently and it's occurring far too frequently. *tr

Tl* the contact owns a 2010 toyota prius. the contact stated that the brake pedal was applied several times and there was an abnormal noise and vibration. the vehicle failed to come to a complete stop. the contact had to apply force to the brake pedal, but the failure continued. the dealer was notified several times, but was unable to replicate and diagnose the failure. the manufacturer was notified. the vin and failure mileage were not available.

At 92,000 miles my vehicle started to burn oil excessively, i made multiple trips to the dealership, they did multiple tesst and continued to maintain(per toyota corporate) that i was within toyota guidelines. this causes me to fill oil every 400-600 miles to be safe and i have found it completely devoid of oil many times.i understand from the dealership that some of the prius models have also had this issue and have been showing up at the dealership but the company has refused to correct the problem. this has me concerned - there needs to be something done about this excessive oil consumption as my engine could completely cease at any time causing a massive safety hazard. i have all the records and formal complaint to toyota on file. i have tried to work with them in good faith until now.

In the past year i have had 2 occurrences of unintended acceleration. the first in february of 2016. i was exiting a parking ramp up hill and stepping on the accelerator. i was driving straight then turning to the left (90 degree turn). when i took my foot off the accelerator, the car continued to accelerate and i was unable to get it slowed/stopped for about ½ a block even though i was applying heavy brake pressure. the car was revving against the brake pressure. no damage or injuries occurred. i took the car to the dealership where i purchased it (purchase date 8/3/13). they checked the car over and found no apparent cause for the acceleration. i took the car home, and it drove normally until 11/26/16. on that date i was driving very slowly in a flat parking lot, and the car began accelerating without my pushing the gas pedal. i was driving straight and then turning to the right (90 degree. i got the car stopped in a few feet by pressing extremely hard on the brake. my car did not hit anything. technicians from the dealership have not been able to find a cause and i have not been able to get past toyota’s customer service department to escalate the issue for more detailed diagnostics. i have attached the timeline of trying to get the car diagnosed and the issue escalated as well as why i don’t think user error is a factor. *tr

Hello. i recently started to experience an issue with my vehicle. my brakes started to make some kind of unusual noises every time i press on them. i've never had that before and i service my car pretty often. i went to authorized toyota dealership and they told me there was a computer issue and they fixed it for $110. it continued to make noises and all of the sudden it began showing abs/brake/vsc lights on my car dashboard either while i was driving or being in the “park” mode. at the same time my brakes stopped working well while driving when the abs/brake/vsc lights were on. i checked the code of the error through the car computer and it showed me “c1391”. i went to the dealership again and they did another check and this time they found that brake master cylinder/booster/abs assembly needs to be replaced with $3,170 price. i attached here the paper that my toyota prime dealership located here in saco, me gave me. i’ve been reading a lot about it online and people with the same type of hybrid vehicles have experienced it. i think toyota needs to look into the issue and acknowledge that it is a common problem in their hybrid vehicles. i service my car all the time, i do oil change and check all the systems very thoroughly, so i don’t understand why we, consumers, have to pay that big of a price for the car repair. i hope you can look into the issue and help me (and to all other car owners) to resolve this kind of issue. thank you.

My toyota prius has not been identified as one of the models in this class action law suit, but approximately four months ago, at 110,000 miles, my vehicle started to burn oil excessively, causing me to have to fill it every 1,200 miles. i take it in for maintenance to the same person at the same dealership since i have owned the car new. i was notified of this problem with the piston rings with the other toyota models and that some of the prius models have also had this issue. this has me very concerned that other owners have been left out of this suit. considering there are millions of prius owners that have stood behind toyota and the prius as the top hybrid on the market,there needs to be something done about this. toyota oil consumption defect class action lawsuit is april lax, et al. v. toyota motor corporation, et al., case no. 14-cv-01490, in the u.s. district court for the northern district of california.

I recently purchased a toyota 2010 prius and four dash warning lights appeared the day after i purchased it when i turned the car on in the morning. the lights stay on for hours to days and go off for similar amount of time. when the lights are on the brakes are much less responsive and the braking action does not charge the batteries as much, never more than 25% of charging potential. the problem was diagnosed as a problem with accumulator in the brake system. i performed a search online and found that there is a recall for such problem, but my vehicle was produced a month after the date of production that would qualify for this recall. i will a pdf copy of the recall i'm referring to.

In 2014 my regular beam headlight went out. the dealers wanted $130 to put in a new bulb saying the bumper had to be removed. my husband bought a bulb at the auto parts store and installed it without removing the bumper. since then i have replaced several bulbs on both sides and was finally told by sylvania that i need to change both at the same time which i did about a month ago. a couple of nights ago, i started the car and both headlights were out and the fuses were intact. i put in two more bulbs, but i can barely see with them although they are lit. the beam is very weak. the dealers want over $100 to do a diagnostic to find the problem or before they will give me a quote of the cost to remedy the problem as stated by toyota in a technical bulletin. this was my third prius, and last one. *tr

Air bag recall - took my car in to kerry toyota in florence ky and they said they did not have time to perform the recall fix that no one there could do it. i had made an appointment a few weeks in advance on their mobile site and specifically said i was bringing my car in for the recall fix.

Headlights have burned out 4 times in the past 3 years- both at the same time and previously one burned out within a week of the other.

Complete brake failure when stopping for stoplight on hwy 53/midway road. resulting in 3 car accident. this was the second brake failure. the first complete brake failure happened when backing out of parking space at work location. brakes were pressed , car kept backing up hitting a parked car behind us. after the first failure the local toyota dealership drove the car and also experienced total brake loss after driving it for a bit. the toyota dealership replace the brake cylinder assembly. *tr

Low beam headlights go out at least 2 times a year. i have to replace the low beam bulbs at least twice a year. wiring seems fine, no damage they just go out randomly throughout the year.

Bad rings in the motor. my dealer said he is seeing a lot of prius's like this. he thinks toyota will have a recall on the prius soon. camry and rav-4 has already been recalled for this reason. my prius just started using a lot of oil @130,000. (1qt per 1200 miles) please enforce a recall for consumer protection.

Tl* the contact owns a 2010 toyota prius. the contact stated that while depressing the brake pedal, the brake pedal was firm causing the braking distance to be extended. the vehicle was taken to toyota of lincoln park located at 1561 n fremont st, chicago, il 60642 who diagnosed the vehicle and determined that the brake booster and master cylinder were defective and needed to be replaced. the vehicle was not yet repaired. the manufacturer was notified of the failure but offered no assistance. the failure mileage was 100,000. the vin was not available.

Upon starting the car, the abs, brake and traction control lights all came on. checked brake fluid and it was at max level. took to dealer and showed code 1391 which showed the brake booster and booster pump assemblies need replacing. it's a known problem with toyota. a voluntary recall was issued for our 2010, but my specific model wasn't included and recall expired in 11/19 or 150k miles. i'm at 150,992. there is active recall for same issue for 2011-2015 models. it's a known safety issue and they refuse to fix it. it's a $3k job to repair for a car that is worth about double that. when this warning comes up, your braking system is not reliable. had this happened while driving, an accident could have occurred. toyota knowing this is a safety issue needs to correct it on all models that show this warning, not just select models.

I have experienced problems with the electrical, oil, and break systems ever since purchasing my certified pre-owned 2010 prius from the dealership in 2013. toyota has never provided a satisfactory answer for what is actually wrong with the electrical system; the problem still remains. toyota also does not have an ideal maintenance plan set up for the known increased oil consumption rate that is directly linked to my model vehicle and has not only not performed routine oil changes but also sent me home after a supposed oil change with zero oil in my tank. but today my main concern that i take issue with and that ive encountered from the get-go, has to do with the breaks. for years i've been telling toyota about how my breaks do this thing where under the right circumstances (those being things like slight bumps or raises in the road, or going over a manhole cover) the breaks not only give out but actually propel me forward with zero chance for stopping which is quite terrifying already and then when you add in other drivers on the road into the equation is a literal nightmare. despite my many efforts for toyota to take a look at them they always refuse any service to them because my dashboard is not displaying any warning signs. also, due to the fact that its not a constant issue, meaning it only happens under the right circumstances which idk where such a precise place exists near the dealership, they cant experience it for themselves. so my concerns are dismissed leaving me to fend for myself whenever these circumstances arise which no doubt an accident seems to be on the horizon. then with ~114,700 miles on the odometer, my entire abs system crashed while i was in traffic. luckily i am a beyond exceptional driver and also have catlike reflexes so was able to manage my way to the shoulder of the road when this occurred. however, with warning lights now illuminated o

Upon turning the vehicle on and starting to drive, the internal combustion engine then starts and experiences about 20 seconds of misfiring to the point the car is without smooth power. this happens at random. if the car was in the wrong situation when it happened it could cause an accident. the same thing will occasionally happen when parked after waiting for the engine to start.

I went to the dealer as i was told after opening a case with toyota,, however the solution was not resolved to my satisfaction. basically. safety parts were replaced from a recall on 08/2013. a few years later i got another toyota notification that if i had these brake booster related failures/lights to bring it in, i would have even if i had the lights without the notification. the other day i had the failure related to the defective parts installed on 08/2013. so somewhere between 08/2013 and when toyota notified me about the lights or the still existing defect, that there was a defect going to happen but did not know when and today i had the failure. i believed that since i had the original replacement brake safety parts replaced that i was driving a safe prius. i feel the second repair for the same parts should be covered since when they notified me they knew there was a defect and chose not to absorb the cost of this remedy.

My car is accelerating while braking. whenever i try to brake on the road while curbing or stopping at the traffic signals, the car skips/slide forward. it’s getting worse on the rainy time though.

I was driving a normal commute when at random, the abs, brake, and traction light went on. the brakes seemed to depress quicker and felt “off”. i was thankfully close enough to home. the brake levels were fine, however after taking the car into the dealer, i was notified that the break booster failed and needed to be replaced. after research, it appears that there was a recall for this part in 2013, as well as a recent legal suit suggesting that toyota did not include all vehicles that could be affected by this faulty part (issue typically shows up around 150k miles). i have a 2010 prius ( included in the suit) with just above 150k and was never notified.

While coming home from work, my wife noticed the brake, abs, and traction control warning lights of the vehicle came on while on the freeway; my wife had to immediately get off the freeway since she noticed that slowing down the vehicle required much more effort than usual. she nearly had an accident going down the freeway ramp. we have scheduled to bring the car in for a fix since this is a huge safety concern to us.

Car stalls while driving and and check hybrid system notification lights up on the dash.

Car shakes badly when changing form electric to gas motor, started smoking in the back.

Vehicle has approximately 120,000 miles. while driving through town or on the highway, our vehicle will intermittently lose regenerative braking. during these instances, the brake pedal softens and greater effort must be exerted to slow and stop the car. sometimes minutes... at other times the next day after the car has sat in the garage, the indicator lights will all turn off and regenerative braking resumes normally. this creates a very unsafe situation as it can be unpredictable how much pressure to apply to the brakes. this is been noticed at slow speeds, highway speeds, in turns, or traveling in a straight line. the vehicle was diagnosed and determined to have a faulty brake booster/actuator. this has created an unsafe and unreliable situation for transporting my family. what is quite concerning is that this occurred with the 2nd generation prius and toyota extended a helping hand by issuing a recall or warranty enhancement. however, my vehicle was produced just months outside of the 13v235000 recall window, yet experiences the same dangerous driving experience as those who were included in the recall. toyota needs to do the right thing and the safe thing by recalling additional 3rd generation prius vehicles and repair or replace all faulty components before more crashes and injuries occur.

Tl* the contact owns a 2010 toyota prius. the contact stated while driving at an undisclosed speed, another vehicle cut in front of the vehicle. the contact quickly depressed the brake pedal and the vehicle started to skid. the contact let up off the brake pedal to straighten the vehicle and stay in her lane. the contact stated that the antilock brakes failed. the vehicle was not taken to a dealer. the contact mentioned that she had taken the vehicle to an independent mechanic for an oil change before the failure and was informed that the vehicle was under recall. the contact called fred anderson toyota of asheville (777 brevard rd, asheville, nc 28806) and informed them of the recall on the brake booster pump assembly. the dealer informed the contact that the vehicle was over the mileage for the repair. the manufacturer was made aware of the failure and provided a case number. the failure mileage was approximately 197,000.

Abs actuator has a leak. it is a $1200 repair. my mechanic, who only works on hybrids, said that this has been happening a lot with my year prius (as well as other years), but the extended warranty only covers 2011 and later.

Tl* the contact owns a 2010 toyota prius. the contact stated that while driving at unknown speeds, the vehicle stalled without warning. the vehicle was turned off and restarted occasionally. the contact received notification of nhtsa campaign number: 18v684000 (hybrid propulsion system). the dealer was not called. the manufacturer was not made aware of the failure. the vehicle was not repaired. the failure mileage was approximately 120,000.

The morning of 8/24/20, i attempted to start my car. a message appears, "check hybrid system". i found there had been a recall, in 2018, that involves a software issue. i had my 2010 prius towed to kolar toyota in hermantown minnesota, on, i believe 8/26/20. they gave me an estimate of $3200 to replace the inverter. i had read about the inverter failure being directly linked to software recall. they said they'd look in to it and later replied to me that, yes, the inverter would be included in the recall and repaired at no cost to me. they said they had ordered the part but my car would not be ready until 8/31/20, at the earliest. they said the part arrived and my car was in the process of being repaired. i contacted them and asked how things were going. the service manager, taylor, told me "for the first time ever we had two vehicles, of the same make but different years, in for the same repair". he went on to say, according to fedex tracking, the part had been shipped but tracking showed nothing else. i asked him if he was sure the tracking was for my part and not the part for the other vehicle. he told me he had no idea for which part the tracking was for. he then went on to tell me we would just have to "wait and see if the part shows up". he went on to say "it could take days or weeks or longer" before we know if the part was coming in. a few days later i called to see if any progress had been made and was told by taylor "the part has disappeared from tracking". i asked him if that meant it had been delivered and was possibly the part for the other vehicle. he basically replied he had no clue. he said we would just have to wait and see, once again. i've been calling every two or three days since then. sometimes he returns my calls. sometimes he doesn't. i don't know what to do at this point. my vehicle is a 2010 toyota prius.

Tl* the contact owns a 2010 toyota prius. the contact stated while driving at low speeds, several unknown warning lights illuminated. the vehicle was taken to local dealer headquarter toyota located at 5895 nw 167th st, hialeah, fl 33015, (786) 235-9734, where it was diagnosed with needing the brake booster to be replaced. the vehicle was repaired but, continued to experience the failure. the manufacturer had not been informed of failure. the failure mileage was 80,117.

Just purchased the car from a used car dealer 8/26/2020 and was driving down a two lane road approximately 45 mph coming up to a stop sign and the brakes went crazy with a continuous buzzing sound from the brakes and the dash abs, traction control, brake system warning lights all came on, would not stop causing me to run the stop sign and make a turn to slow down and finally come to a stop. had the trouble code read and the store read the diagnostic trouble code as c1391 and reset so i could drive the vehicle slowly home. i checked for recalls on this dtc 1391 but my 2010 vin was not included in the recall. they need to recall all of the 2010 prius.

I was comfortably driving my 2010 toyota prius down a city street on a thursday afternoon--about 25 mph, light traffic--when suddenly--without any trigger or warning--i lightly pressed down the brake pedal to slow down for a speed bump, and the brakes shuddered, the brake pedal seemed to twitch, and the car started making a loud shrieking and grinding noise every 3-5 seconds. for the record, my 2010 toyota prius has been regularly serviced at my local toyota dealership since i purchased it in 2018. the loud shrieking felt like it was coming from below my feet and from the drive shaft. i pulled over--the shrieking and grinding continued. i stopped the car--the shrieking and grinding continued. i got out of the car--the shrieking and grinding slowed after a few minutes. when i turned the car on again, the shrieking and grinding started and the car was beeping in a way i’d never heard before. fortunately, i was about 4 blocks from my local toyota dealership. i asked them if i was safe to drive the four blocks or if i should get the car towed, and they said i should be safe to drive. i drove to the dealership with the car shrieking and beeping. the brakes felt squishy and unreliable, but the dealership has said i should be fine. i dropped off the car. the next day, i got a call from the dealership saying that my brake booster pump and brake cylinder assembly had totally failed. when i asked the technician if there was something i could have done to prevent this, he said, “no, this is just something that happens to these cars.” the brake failure occurred on thursday, august 27, 2020. the phone call from the dealership occurred on friday, august 28, 2020.

Previous recalls for a 2010 toyota prius (nhtsa campaign number: 13v235000) and a 2019 toyota customer support program (csp zjb) has acknowledged an unsafe failure mode in the vehicle where the brake booster assembly fails due to high pressure and causes the automobile to have difficulty stopping. on september 4, 2020 while driving down the road at roughly 40 mph, i experienced indication lights consistent with the descriptions outlined in the safety recall and toyota support program. my automobile also had extreme difficulty coming to a stop from 40 mph and i had to unsafely pull to the shoulder of the road at speed to avoid colliding with the automobile in front of me. the toyota csp zjb does not cover my vehicle due to time and mileage of the vehicle, but i feel this safety critical system should have been replaced prior to me experiencing a failure. toyota selectively only replaced brake booster assemblies outlined in the recall and the csp, if the automobile was experience issues. toyota stopped short of preventative safety measures of replacing this assembly prior to failure, leading to an almost collision event for me. independent research has identified this issue has been responsible for other toyota prius accidents leading me to believe this is a safety issue that should be addressed by the nhtsa before others experience a critical safety failure at no fault of their own.

The red brakes light, abs light and the 'yellow skidding car' icon lights all come on together, but intermittently. the brakes often feel difficult to press down upon starting the car. ofter when the lights are on, the brakes feel spongy, or as though they may not stop the car. i took the car to the toyota dealership and they concluded that the master cylinder and other parts needed replacing. i found out that toyota has had lots of problems with these brake cylinders.

While in motion driving at 50 mph, warning beep signaled and car started slowing down. notification on the dashboard read "check hybrid system". vehicle eventually slowed to a stop and put itself in neutral automatically. took it to a mechanic who said it is the inverter/converter.

The cars starts does not stay on if i try to drive it will turn off and die out .

While driving on highway the vehicle loses power causing it to locse speed quickly. this is extremely dangerous if you are in an area where it is hard to pull off. it will drive 42mph until the battery dies. this is more common than most issues with this model. please make toyota replace the engines in these vehicles. "check hybrid system"

Got code abs pump c13591 from toyota dealer, they refuse to fix under warranty

Tl* the contact owned a 2010 toyota prius. the contact stated that after driving his vehicle for seven hours, the contact had parked the vehicle in his friend's driveway. thirty minutes later, the contact's friend received a knock on the door from a fireman asking him who owned a prius. after the contact identified himself as the owner, the fireman informed him that his vehicle was involved in a fire. a fire report and police report were filed at the scene. no injuries were reported as result of the fire. the vehicle was destroyed by the fire and was towed to an independent junk yard. the contact notified the manufacturer of the failure and the contact was given a case number. the contact was also informed that an investigation would be launched regarding the matter. the contact had sent photos and email correspondences to the manufacturer; however, he never heard back from the manufacturer. upon investigation, the contact discovered a recall on his vehicle under nhtsa campaign number: 18v684000 (hybrid propulsion system) which he linked to his failure. the contact had not spoken to a dealer about the failure. the failure mileage was 77,000.

Abs system went out.

I experienced a significant loss of brake performance accompanied by many warning lights on the dashboard, including one that indicated a problem with the abs brake system in my 2010 prius. upon immediately taking the car to the dealership, i was told that toyota extended a warranty program (zjb & zkk) for the source of the problem abs brake actuator/master cylinder failure, but that i was not eligible for the warranty coverage because the deadline had expired. my car was under 150,000 miles, as required by the warranty, and displayed the correct failure code as required by the warranty. but, since my car did not experience the problem or display an error code before the end of february 2020, i was told that i was ineligible. i was informed that i would have to pay over $4100 for a repair through the dealership, buy a new car or take my chances and drive the car 'as is' until i could find a cheaper solution. the cheaper solution would be to find another abs unit at a salvage yard, and have a non-toyota certified mechanic install it. there is nothing to indicate a salvage yard unit will not simply fail again. i was well within the 150,000 mile limit of the warranty. so, i am to accept responsibility for the repair of a part that toyota admits is faulty, and would have replaced if the problem would have surfaced a mere six months earlier? i believe toyota's warranty extension to be a meager attempt at appeasing the nhtsa and other authorities so they do not have to launch a full scale recall. they are endangering the lives of hundreds of thousands of people who depend on these cars on a daily basis, as they should not ask their customers to experience a major brake failure before the manufacturer will agree to fix a known problem (or not fix it, rather, as the time limit has expired). toyota is putting profits ahead of safety, during a pandemic. i the nhtsa to help us.

Brakes system warning indicators light up. brakes feel weak, need to step harder than normal to start slowing down. i looked this up on the internet and this a known defect that toyota covers under 'customer support program zjb' for a certain period only. of course it happens right after that coverage period. this should be a recall as it affects a known safety issue.

The brakes went completely out on the vehicle while driving on the highway. i had no ability at all other than the emergency brake. the dealer said that the cause was the brake booster and master brake cylinder.

Prius has less than 100k miles and has been running perfectly. today while driving, the brake, abs and traction control lights came on simultaneously and began alarming, while suddenly my brake locked up. this could cause accident and injury if it occurred under the right circumstances. apparently there was a previous brake booster recall that i was never notified of and which has since expired. this recall should be reissued to include the many 2010 priuses affected by this problem.

Tl* the contact owns a 2010 toyota prius. the contact stated that at start-up the air bags warning light illuminated. the vehicle was taken to parkway toyota located at 50 sylvan ave, englewood cliffs, nj 07632, to be diagnosed. the contact was informed that clockspring spiral cable needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was approximately 88,680. *ln consumer stated prius was not part of the recall.*jb

The brakes failed on the vehicle and i lost all ability to stop. several dashboard lights were triggered about loss of abs and braking. i was able to stop the vehicle only through the emergency brake. the toyota dealer indicated that the problem was a failed brake booster and brake booster pump assemblies. there have been numerous complaints about this issue and tpyota needs to recall and repair this iissue.

Traction warning light, brake light and abs light all came on at same time while driving on the highway. i was told by a toyota dealership it is a malfunction with the brake booster which is roughly a $3000.00 repair job at toyota dealership. customer support program "zjb" was created by toyota north america for this issue in response to thousands of prius models experiencing this severe malfunction, however, my 2010 prius is no longer eligible for coverage for this repair, even though other prius models are still eligible for complete coverage for this repair. this is a safety hazard and toyota north america needs to stand by coverage for this grave malfunction for all models regardless of year or mileage. the dealership told me the car is not safe to drive, the brakes are not operating at full capacity. this is a safety hazard and happened while i was driving on the highway.

My abs system started showing signs of problems, and i started getting codes for all sorts of brake-related issues. my brakes ended up locking up and not working, and my battery in my car died because it was the brake system was not able to recharge my battery. even though i started having issues with it in february, apparently toyota said that because i had a 2010 prius, that since november 31, 2019 had passed, the recall/extended warranty "ran out" on it. even though this is a problem that obviously wasn't fixed in the first place. so when i took it to the dealership to get a diagnostics ran on it, they said that they needed $3,200 to fix the vehicle. this included both the purchasing and installation of a new brake booster/master cylinder assem and an abs pump motor assem. i obviously do not have the money for the repair and they are telling me to go kick rocks. this is not right and because of the brake issue not being fixed in the first place, it then allowed my battery (which runs around $1,500) to get completely drained and prevented it from being properly recharged by the brake system.

Tl* the contact owned a 2010 toyota prius. the contact stated that while her husband was driving at 40 mph, the vehicle in front suddenly stopped, the brake pedal was depressed however it failed to engage causing him to rear end the other vehicle. the contact mentioned that her husband was already depressing the brake pedal when they completely failed. the air bags did not deploy. the contact stated that the front seat passenger in the other vehicle was transported to the hospital by ambulance due to feeling nauseous. a police report was filed. the vehicle was towed to auto body repair facility where it was awaiting inspection by the insurance company. the contact stated that the vehicle was a possible total loss aas the radiator and engine was damaged. the vehicle had been serviced at clearwater toyota (21799 us hwy 19 n, clearwater, fl 33765 800-667-905) for a brake issue. the dealer refused to repair the brakes under an extended warranty due to an incorrect consistent failure code. the manufacturer stated that the sensor was not alerting enough for the repairs to be covered. the failure mileage was 200,000.

Vehicle shuttered and warning lights came on while driving on busy roadway. was able to pull onto side street and stopped vehicle. outside temperatures were over 100 deg f and my wife was alone with the vehicle. attached mechanic estimate lists codes and indicates the inverter failed. we had the ecu updated in 2016 to avoid this failure but believe toyota's ecu flash failed to fix the issue. subsequent extended warranty did not cover this vehicle's vin # according to toyota dealership we contacted on 05/29/2020. *tr

On friday, may 15 2020 i turned on my car and saw abs, brake and vehicle traction lights illuminated. the brake peddle also felt odd. within 30 minutes i took it to my local toyota dealer. the service writer had a clear idea of what was happening as she said this has been happening a lot to prius models. sure enough the diagnostic code c1391. i was told i needed to replace the brake booster/pump assembly which would cost me $3,000! upon research, my car was covered under a tsb till november 30, 2019, but only if they failed. there was no recall issued by tms to pro-actively fix a known brake deficiency. my car has 159,000 miles, i have never had anyone service my vehicle besides toyota dealerships (except tires). i called tms to corporate to see if i could be offered assistance, but was flat out denied (i can provide that case number if needed).i find it odd that toyota began phase2 on 2011-2015 for same issue that lasts till april 2021. it is unsettling that if toyota knows about the brake booster and pump problems, why they don’t have a recall, but rather a wait and see if it fails under their “secondary/enhanced warranty”. upset that if this happened 5 months ago, this would have fallen under their guideline to repair.

While driving on the highway the abs warning light, brake light and traction light all came on at once, took to local toyota specialist, diagnosed the code as c1391, an abnormal leak in break booster accumulator. mechanic informed me that this issue was previously under safety recall and my vehicle had the proper repairs done, clearly this is an ongoing safety issue with this vehicle that is not being properly addressed by toyota. it is also an extremely expensive repair which toyota needs to be financially responsible for. *tr

Brakes and vdc system constantly engage during u-turns, tight turning circles, causing the car to brake unexpectedly. while not accident has happened, it has caused a few near misses as my window to turn shrinks because the car is braking. *tr

Brakes failed while driving car (in motion) which almost caused an accident. the red warning "brake" light, yellow "abs" and yellow traction control light all illuminated. this apparently is a known issue for the toyota prius and i have contacted them concerning the issue but they will not pay to fix the problem. my car cannot be driven at this point. this issue is a serious hazard and could easily result in an accident. they need to issue a recall. *tr

I own a 2010 toyota prius with 97k and it is immaculate. in march 2019, the instrument cluster (an electronic component in the dashboard containing the gas gauge, speedometer, and gear position) stopped working entirely one day upon starting the car. i researched the issue and it's my understanding that a faulty capacitor on the logic board within the instrument cluster is the culprit. toyota can replace the instrument cluster but only at my cost and for over $1000. toyota issued a warranty enhancement notice to extend manufacturer warranty on this instrument cluster problem, but it only applies to 2004-2009 models. this electronic issue had not been entirely resolved by toyota in later models as many others are faced with the same issue. am i monetarily responsible for the repair of the instrument cluster? does nhtsa have ongoing support to prius owners for this issue? should i file a small claims lawsuit? *tr

Warning lights for abs, brake and symbol indicating traction control is operating all lit simultaneously with a corresponding change in brake pedal feel. toyota dealer diagnosed brake booster failure and initially quoted $1,915 to repair then called back to revise this to $2,915. there have been recalls on this part just not covering my vin. *tr

Code c-1391 leak in brake accumulator.these should be a recall with toyota putting a bad brake accumulator in prius model.i notice it was a secondary recall with this part.toyota know this is a safety problem when this happen the car goes to manual breaking and you can lose control of the car.please look into this problem. *tr

Low beam started getting dim, but were brand new. they both suddenly failed on the highway almost causing a crash. i replaced bulbs and they were dim again. i went to buy the top line headlights thinking that was the issue, but i discovered the passenger side headlight assembly was corroded and melted. once i turned the car on it began smoking. i can't install any lights now. *tr

Factory defective paint resulted in peeling paint. contacted toyota by email & phone & they refuse to reimburse me $3,529.04 that i paid to have my car repainted, insisting that my toyota prius iii is not included in the defective paint recall. i have a case [xxx] on file with consumer assistance office metro west. you have my permission to contact fred nassif at bridge st. auto body, 781-326-8707 for assistance regarding the peeling paint. he can provide you with verification & pictures.*dt information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).”*jb

I brought my toyota prius to toyota dealer as abs alert was on and i lost controlling the brake. toyota dealer gave me an estimate for repair at $2,850.00 ( p1391 abnormal leak in accumulator pump rec master cylinder with brake booster and brake booster pimp assembly) due warranty enhancement expired 05.09.2020 or 150,000,miles. i've got abs alert in the beginning of may'20, however, due to covid-19 stay-home order, i had to stay home and won't able to bring my car until end of may, .2020. i was advised by toyota dealership to contact toyota customer relation as they may consider to extend the warranty, so i contacted toyota customer relation( actually i was transferred to financial department) and they denied to extend the warranty, and they repeated as " warranty is warranty" . i was very disappointed with toyota's unkind decision and service under covid-19 situation. i read toyota 2010 has problems of brake issues, so i want toyota take a responsibility to fix my brake problem. *tr

I was notified by toyota that my vehicle had two recalls. one of these was involving the inverter pump. i visited a toyota service dealer february 15, 2020 to have these recalls taken care of. in the beginning of may 2020 i had driven just a few miles from my house when all of my warning lights came on. one of which said "check hybrid system". i slowly drove my car to the nearest toyota service a few days later. i had not driven my car otherwise after the lights came on. i received an update from toyota saying my inverter pump had failed and that i needed a power module. they estimated a total charge of $3,500 would cover the costs of fixing my car. i realized that i had been at a toyota service just months before to get my recall taken care of, for this exact inverter pump issue. it was confusing to me that the part toyota was supposed to fix, was all of a sudden broken. did they not take care of this in february as they were supposed to? not only were they trying to charge me, but they were denying that they had to fix it for free since the problem was "fixed" already by toyota in february and since it has broken afterwards, that it is no longer their responsibility to fix. if it was really fixed in february how could it be failing just three months later. they seemed to be unaware that there was actually an extended warranty on my vehicle model for this issue specifically. i had come across this fact online after researching the problem myself. they called me back to agree that there was in fact an extended warranty and that now they could fix the inverter. it is concerning that they would not already know that the inverter pump was a recent recall, and that my car had an extended warranty. toyota should be aware of their own recalls and warranties. i was still charged over $700 to have my car fixed. i do not believe i should have been charged anything. *tr

Defect within the brake booster pump assembly. if this defect occurs, various warning lamps on the instrument panel made illuminate, i experience increased stopping distance, reduced hydraulic pressure within your brake system, the deactivation of brake assist, and/or the deactivation of vehicle stability control. toyota has previously issued at least two safety recalls – d0h and k0l – designed to prevent similar dangerous occurrences. however, hundreds of thousands of generation iii prius vehicles (2010-2015 model years) were excluded from those safety recalls.

Toyota usa failed to honor repair defect within the brake booster pump assembly. when this defect occurs, various warning lamps on the instrument panel made illuminate, i experience increased stopping distance, reduced hydraulic pressure within your brake system, the deactivation of brake assist, & the deactivation of vehicle stability control.toyota previously issued at least 2 safety recalls. designed to prevent similar dangerous occurrences. however, hundreds of thousands of prius models 2010-2015 were excluded from those safety recalls including my 2010 model. as of today toyota usa filed case number 2005052305. safety recall in torrance california dated june 4, 2013 stated toyota sales usa was conducting a voluntary safety recall involving over 87,000 model 2010 toyota prius however i called toyota today and the insisted my vehicle was excluded even though in barely has 100,000 miles we just began to experience these brake symptoms. customer rep insisted it was toyota voluntary recall not enforced so my vehicle did not even qualified for a customer support service. please help us have toyota fix this safety issue asap before someone has a mayor accident. warning lights for abs, stability control, and warning lights all came on at once. brakes became spongy when pressed. was able to still brake but with much more effort and not confident in the braking. i had it towed to a local mechanic and the diagnostic error code registered "c1391". per mechanic this is for abs accumulator, or booster pump failure or leak per mechanic. this happened out of the blue, no warnings. per toyota the part required are cylinder assembly brake and brake pump assembly. cost to repair these parts per toyota would be estimated at $2700.. attached video of actuator's loud noise it produces & dashboard showing abs failed& brakes lights/also failed attempt to solve this with toyota usa. *tr

The prius have been great and have been serviced with oil changes, spark plugs etc. it runs like a champ with 159k miles, but all of a sudden one day, the traction control, abs, and brake lights all came on at once. the brake pressure feels softer and that whirring noise is heard every few seconds. dealership said it was the brake actuator and would cost 3k to fix. apparently there was an extended warranty for it but it ended in november 2019. attempted to call toyota, but no help. *tr

I have “check the hybrid system “window on dashboard. independent mechanic checked and told me that it has problems with inverter. toyota has and had multiple recalls but they are doing some type of reprogramming which isn’t helpful. it is expensive and common problem.

While driving, we made a left turn on a city street, warning lights for abs, stability control, and warning lights all came on at once. brakes became spongy when pressed. was able to still brake but with much more effort and not confident in the braking. i had it towed to a local mechanic and the diagnostic error code registered "c1391". per mechanic this is for abs acculator, or booster pump failure or leak per mechanic. this happened out of the blue, no warnings. luckily while driving we were driving in town and at a speed of only about 15-25 mph and we were not on the free way or at high speed. per toyota the part required are cylinder assembly brake and brake pump assembly. cost to repair these parts per toyota would be estimated at $2700. local dealership wouldn't do anything until it registered the code again. the dealership service advisor, said until the code is triggered again they wouldn't do anything. also after the code was reset the brakes worked normal again. this in my opinion is a safety issue! *tr

Tl* the contact owns a 2010 toyota prius. the contact stated that upon starting the vehicle, the brakes warning light, abs warning light and several other warning lights illuminated. the contact took the vehicle to toyota of santa barbara located at 5611 hollister ave, goleta, ca 93117, (833) 779-4500) to be diagnosed. the contact was informed that the brake booster assembly needed to be replaced. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was 116,000.

I was driving at a speed around 60 mph and had to break suddenly and the car did not break right away and took more than normal to slow down. i just had the inspection a month ago and i was said i had plenty of breaks left.

When i was driving on west paces road in atlanta, i tried to brake and the barakes did not work . therefore i went directly into the back of the car in front of me. i must precise that the brakes pad were new, the brake liquid was ok. i was driving at 30 miles an hour.

Tl* the contact owns a 2010 toyota prius. the contact stated that while traveling 20 mph, the anti-lock brake system, stability control and brake warning indicators illuminated and the vehicle brake ability began to delay. the vehicle was driven to an independent mechanic, they determined that the brake booster had to be replaced. the vehicle was not repaired. the vehicle was not taken to a dealer for a diagnostic. the manufacturer was not notified of the failure. the approximate failure mileage was 230,000.

Brakes fail when applied steadily while moving on a wet or bumpy surface causing the car to continue forward unless the peddle is pressed again firmly. this happens on the city streets while moving in a straight line. this appears to be due to the known abs problem in the 2010 prius and was supposed to have been corrected byway of a software patch, which i am told by chuck patterson chico toyota has already been done and no further ehlp could be expected from toyota.

Hybrid system shut down while traveling. loss of power hazard. hybrid system malfunction indicated along with loss of traction and trouble indicator on dash. *bf

Noticed brakes pulsing at very slow speeds. looked up symptoms online and determined it was from brake booster leak issue. took to dealership but because no codes showed up on diagnostic machine, was told nothing wrong. (that was at 147,000 miles.) fast forward 6 months and warning lights came on while driving and braking became very spongy. took back to dealership and needs brake booster pump and brake cylinder assembly replaced. now has 155,000 miles and is 5000 miles past warranty. long story short is that i was able to determine an issue long before their computer could detect anything. but because i'm now past warranty, i have to pay $2600 for repair.

Both the low beam lights are of a problem with recall which toyota expired the recall on 10/31/2019. i tried few times last 3 years to get it fixed with toyota portland but they always said 1) don't have parts will call back once available 2) if you have issue we will fix it otherwise now now. now that both were off and i had to use high beam, i took to toyota beaverton, or. they said recall is expired. why will recall expire if it is safety issue? i called toyota customer support they said expired and you have pay fo yourself. the cost is not just bulbs but internal wiring kit which starts from $600. i am taking it to toyota portland today as my student daughter needs the lights to drive. we are both in different states (ca and or). csp info - "customer support porgram zhb certain 2010-2011 model prius coverage for halogen low beam headlamp bulbs)

The car i have 3 dash lights we pull the code through computer it was c13 91. that means the car have an actuator it's not working so the brake system is not working properly and the abs light traction light the brake light are on all the time . sometime they go off and sometimes they turn back on usually it's more on time than off time. i did research and find out very common with 2010-2015 prius model went to toyota dealership at riverdale west springfield massachusetts no help. it's a known problem they agree but my car is 10 years old or 150000 miles over so no warranty please help i am a poor uber driver 4 daughter and wife i am the only bird feeder [xxx] is my cell and [xxx]. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

I was driving on the highway at about 60 mph when the brake light, abs light and slide light illuminated on the dash. i took the car to the dealer and they said it was the brake actuator. when i researched this,i found that it is a known problem totoyota and they did a voluntary recall. my question is why would there be a voluntary recall on a part that is vital to the safety of the car and has a known defect? because it was a voluntary recall they could arbitrarily select a cut off (150,000 miles) instead of ensuring the car was safe. this is only for 2010 prius.

Tl* the contact owns a 2010 toyota prius. the contact stated that while driving out of a parking lot, the vehicle stalled. the contact stated that an orange (master warning) and a p-symbol warning light was illuminated. the vehicle was towed to umansky toyota dealer, (1357 richmond rd, charlottesville, va 22911) where it was diagnosed however, the technician could not duplicate the failure. the vehicle was not repaired. the contact stated that that the vehicle was previously repaired under nhtsa campaign number: 18v684000 (hybrid propulsion system). the contact stated that the vehicle was taken to an independent mechanic where it was diagnosed however, the technician was unable to provide a cause for the failure. the manufacturer was contacted and informed of the failure. the failure mileage was approximately 51,788.

Tl* the contact owns a 2010 toyota prius. the contact stated while parked on a small hill, upon starting the vehicle and shifting to drive the vehicle started to roll forward down the hill. the brake was applied but failed to engage as the vehicle collided with a neighbor’s fence and trailer. the brake warning was light illuminated during the failure. the contact stated that the passenger sustained bruising to the knee as well as he also sustained bruising to the knee that required no medical attention. a police report was not filed. the vehicle was taken to lakeland toyota (2925 mall hill dr, lakeland, fl 33810) where the brakes were repaired. the contact stated that the manufacturer was notified of the failure and the vehicle was inspected by a toyota engineer assistance field inspector. the failure mileage was approximately 197,356.

I bought this car around mid year of 2019, and when i first used it in the highway coming back from work, there was traffic and i noticed the breaks not responding well. this has happened many times since i bought it, in the streets as well. there's also a orange light saying that it needs maintenance. i have taken the car about 3 times to the person that sold it to me because he has a car shop and it still does the same thing.

My brakes have failed due to a faulty brake accumulator and brake booster on my 2010 toyota prius. i noticed this problem when attempting to come to a stop at a redlight. the brakes felt spongy and unresponsive. i narrowly missed colliding with the car in front of me by swerving onto the shoulder. toyota previously acknowledged this faulty part but claims that i missed the deadline by 35 days to get it fixed. the repair costs roughly $4,000 which toyota has refuse do to accept responsibility for. i cannot afford to fix this and believe that it is irresponsible for toyota to put their profits above the safety of its' customers. i do no this believe that it is ethical to put a deadline on a safety concern of this nature.

Tl* the contact owns a 2010 toyota prius. the contact stated that the brake booster assembly on the vehicle was defective and failed to operate as needed. the vehicle was taken to (greentree toyota 87 federal rd, danbury, ct 06811) to be diagnosed. the mechanic was unable to retrieve a fault code. the vehicle was then taken to (curry toyota of connecticut 832 straits turnpike, watertown, ct 06795) for a second diagnosis with the same results. the contact became aware of nhtsa campaign number: 13v235000 (service brakes). the vehicle was not repaired. the contact received a buyback offer from green tree toyota but declined the offer. the manufacturer was notified of the failure. the failure mileage was 93,000.

Well-maintained, dealer-serviced vehicle sputtered and stalled while driving on the freeway at highway speed. was fortunately able to coast to a stop on the shoulder, but vehicle would not restart. dealership identified the problem as a fuel pump failure, which occurred with no warning.

Air bag did not deployed at the time of accident. damaged/rip apart front bumper...car is total loss as per insurance adjuster. other collided honda cr-v had all its air bags deployed. none on my prius. accident happened at major intersection ,when green light turned on i paddle my car , other car honda cr-v came at a speed to make left turned and hit my front bumper.

While driving the vehicle the hybrid system failed as per notification on the dashboard. the car was operable but i was not able to drive above 40 miles per hour. i was told by the certified toyota dealer that the inverter failed and they were not able to provide a reason why it failed. there was a previous recall on the inverter in 2014 to fix a software issue which was repaired. i was told by the dealer this recent incident was unrelated.

While driving back from running errands my car's lights on the dashboard started to come on and noises started to start happening. i was lucky i was only a few streets away from my house so i decided to drive back home. the break was really hard to press. the brake felt like it was a rock and hard to press. i drove with my hazards on unsure of what could happen while driving. there was something wrong and the car started to beep and i was worried the car might fail to brake so i started to drive very slowly. the brakes were so hard to press. i took my car to toyota the next day and they said there was a defect with my brakes. they had the vehicle for a few days and returned to me saying it was fixed. needless to say this was a very scary situation to be in. i drive a lot. if i had been further away from my home this would have put me in a very dangerous position. i could've been stranded or drove on the freeway in this condition unsure of what was happening. my car could've stopped braking, i could've gotten into a big accident and injured other drivers around me. this is a very serious issue that should be recalled now and save other drivers! in california people drive up to 80 mph on the highway-if we are behind a car and the brakes malfunction you can imagine what will happen to the driver and anyone involved! when i heard toyota was not recalling this on all prius's that might be affected it really scared me. this is unsafe.

Hazard lights flashing when driving forward or reverse dependent on the speed of wheel rotation. i am told that my skid control ecu as well as the brake booster and pump are bad and need replacing. i keep reading about this issue, but toyota says it is not a broad issue. it is not clear what systems have failed or what risk there is in driving.

When the vehicle passed 100k miles, it start consuming oil excessively. now it needs a quart every 200 miles. i found out from the net that this is a known problem that toyota has not resolved

The night before, everything was working fine. the next day, i start my car up at 4pm-5pm, first time i started my car and i have new lights on my dashboard. the ebrake light, abs light, brake system light, and traction light. i release my ebrake and the ebrake light is still on. concered i checked the break fluid and the 12v battery and those were fine. drove the car around the block to see if there was an issue or if the lights were just on. the brakes were almost completely out the vehicle would only stop when i put my foot to the floor. i end up taking the vehicle to my local toyota dealership were after four hours of looking around, informed me that it was the brake actuator and the booster pump. which also came with a bill of $3000 to fix it.

Air bags failed to deploy in car crash: my 2010 prius was stuck by another car who ran a red light, in the front right (passenger side). the car that struck me was traveling approx 35mph and pushed my car (also traveling approx. 35mph) into the path of a wooden telephone pole that suspended the traffic lights over the intersection. my car traveled about 20-30 feet further and stopped when my car hit the pole head on. the telephone pole broke in two in the impact. none of my air-bags deployed. the police report is incorrect regarding the airbags. i have contacted the police department to amend the report. as seen in the accompanying photographs, the air bags did not deploy, contrary to the police report.

First the driver's side low beam failed, followed by the passenger low beam headlight days later. after replacing both lights, the driver's side low beam failed followed by the passenger's low beam.

The best i can get is 40 mpg with mostly city driving. which is so much worse than their claimed 55+ mpg. anyone has the same complain ?

My 2010 toyota prius was impeccably maintained by desert toyota of tucson, all service records kept. oil was changed every 5,000 miles rather than the dealer-recommended 10,000. this was my 4th toyota and i expected it, like my other toyotas, to have no significant problems for years. but suddenly in 2017, when the engine turned over 107,000 miles (thus making it out of warranty), i happened to check the oil (several thousand miles before the next service was due) and found it near the bottom of the dipstick. it was fortunate that i checked it because i was able to add oil and save the engine. the car performed as before, but continued to burn about a quart of motor oil every 1000 to 1500 miles. there was no evidence of either smoke from the exhaust, or oil stains underneath the car. my service person at desert merely shrugged and said this kind of thing happened occasionally, offered no remedy or contact with the toyota rep. i began to search the internet, finding that there have been thousands of 2010 toyota priuses with this problem. i have kept the car on the road but am awaiting a reimbursed remedy from toyota, possibly through a class action suit. this oil leakage poses incalculable safety risks to the environment in pollution and unpredictable occurrences. toyota owners do not expect a $5000 engine repair on a $25,000 car within 7 years of purchase, nor should they be responsible for a toyota defect which conveniently occurs when the car is just out of engjine warranty.

As i was driving 55-65 mph on the highway, the check hybrid system alert came on, and all of a sudden i lost power. i was able to make it home but going up hill it would not go faster than 35 mph, and 40-50 mph on flat ground. this happened on a busy highway where the average speed is 55-65 mph

Toyota prius low beam headlights suddenly go out due to known issue with wire harness. no recall issued and owner is responsible for cost of repair

My 2010 toyota prius slides while breaking when i drive over a bump or a whole the car slides while in motion on city streets or highways. these occurrences happen while driving straight or turning. this occurs all the time when the roads are dry and it is worst when it is wet outside, ice, rain sleet or snow.

I was making a left turn, creeping into a parking space, in a residential area. when i pressed the brake pedal to stop the car, the car accelerated instead. i then slammed on the brakes and the car accelerated again, causing me to go over the curb, over the sidewalk and knock down a fence and shed. i turned the vehicle off, some kind bystanders took the debris off the car so that i could get out. i then called police and the property owner, as well as my insurance company. i am honestly scared to drive the car again, as i do not want this unintended acceleration to happen again. i will be notifying toyota, and the repair shop working on my car has already been informed.

Brake/abs and stability system failure. possible actuator or accumulator. touota knows there is a fault and hides behind a software update. system fails and causes unreliable braking with increased force to apply the brakes. brakes apply so hard at times the rear passengers heads hit the rear seat.

Tl* the contact owned a 2010 toyota prius. while driving 60 mph, the front wheels shook and the contact lost control of the steering wheel. the contact crashed into anther vehicle, which then caused the other vehicle to crash head on into a median. the air bags deployed. there were no injuries. a police report was filed. the vehicle was deemed totaled and was towed to the contact's home, awaiting an investigation. the cause of the failure was not determined. the dealer and manufacturer were not notified. the contact referenced nhtsa campaign number: 18v684000 (hybrid propulsion system). the failure mileage was approximately 120,000.

When driving at higher speeds than 40 mph, my check engine light, and check my hybrid system light is turned on. when it turned on, i was unable to accelerate, however i was able to pull over, and restart my car. i have recently come in to get a software update for the factory recall related to the issue. however my inverter has been damaged as well. on this website it states if my inverter is damaged related to the recall, it will be repaired free of charge. however the toyota dealership charged me for diagnostic, and requested payment for the replacement of my inverter. i also have given toyota a call as well, they have stated that the recall only will consist of a software update. i was unable to get anyone from toyota to help me with my repair of my inverter thus far.

Vehicle actuator brake pump assembly making squeaking barking noises when the brake is pressed down and held down the brake pumps back at me. i took to toyota they charged me for running codes and two brake bleeds. agknowledged that it's the break actuator pump assembly that is a extended warrenty but will not fix and charged me because the warning light system is not coming on. this should be a recall not an extended warrenty. my brakes bark and push back every time i brake. this doesn't seem safe to drive on the freeway and not good if an accident incurs because i had to wait until my brakes didn't work. please make a recall and not just an extended warrenty.

Brake failure and car went up curb, knocked down stair rail, hit tree and turned over on side

Brakes went completely out and emergency noise was beeping loudly in car. talk to mechanic and he said brake actuator is bad and there was a recall but toyota won’t acknowledge and repair

While the car is in motion it stalls in the road/highway and does not accelerate. when taken to the dealership, they diagnose error p08a0 error code: replace hybrid battery pack.

“takata recall” as i was merging on the highway this morning i got the big warning light on my dash and the engine light along with a message on my screen saying check hybrid system. ever since my hybrid system shut down and never came back on.

As i was driving on a road, about 25 mph, while my foot was on the accelerator pedal the car just decreased it’s speed to a stop as i continually pushed my foot on the pedal.

Tl* the contact owns a 2010 toyota prius. while operating the vehicle, the “check hybrid system” warning indicator displayed and the vehicle stalled. moments later, the vehicle restarted, but the warning indicator remained illuminated. the failure occurred on multiple occasions. the cause of the failure was not determined. fred anderson toyota (9101 glenwood ave, raliegh, nc) was notified. the manufacturer was not notified of the failure. the failure mileage was 207,000.

I took my 2010 toyota prius to dealer ship for a software update, and now the hybrid system kept having problem, once i disconnect the 12v battery, the car will do fine for like a week, then the hybrid system will shut down, it didn't happen before the software update.

Driving with cruse control set at 72 mph, driving on 4 lane interstate. master warning light came on along with the following warnings "check hybrid system" & "check pcs system", all dash lights lit up. engine stalled unexpectedly and resulted in no power when pushing gas pedal. steering was not compromised. was able to cross 3 lanes on the interstate to the shoulder with no power and the car decelerating rapidly, again with no prior warning of any issues. turned car off and restarted, was able to drive approx. 25 feet before the engine shut off unexpectedly again leading to a complete loss of power. breaking and steering were affected after restarting the car.

Started car one morning, immediately noticed the “abs”, “brake”, and “traction control” warning lights were on simultaneously. took the car for a drive around the corner, and immediately noticed brakes were very soft and unresponsive. pedal literally sinks to the floor while air can be heard leaking from the system/pedal. . also noticed the brakes no longer recharge the system, and they also feel jerky at times. i checked the brake fluid reservoir, and noticed fluid was halfway between max and low. perhaps a leak somewhere in the system? i contacted my local toyota dealer and will have them take a look at it on 05/10/2019 according to some research i conducted, this is a known issue in the 2010/2011 models. supposedly, over time, vibrations can actually crack the line(s) feeding into the brake master cylinder, and thus resulting in this fault. toyota should definitely be more communicative about these issues. i have owned this car for 4 years, and have never heard of this before. currently not driving the car at the moment, as i do not feel safe

Tl* the contact owns a 2010 toyota prius. while driving 70 mph, the vehicle stalled and the "hyper" system failure warning indicator illuminated. the vehicle was towed to toyota of seattle (1925 airport way s, seattle, wa 98134, (206) 382-4300) where it was diagnosed that the egr valve and intake manifold needed to be repaired. the vehicle was repaired, but the failure recurred. the dealer stated that the fuel pump needed to be replaced. the fuel pump was repaired by an independent mechanic. the manufacturer was made aware of the failure. the failure mileage was 180,000.

My brakes has always had a weak feel and it would lose stopping power when braking on a bumpy road. its almost like, the brakes releases when you hit a bump. there are currently two recalls for the 2010 prius but for some reason, my vin number is not included in it. is there any way we can get the dealer to perform the recall? its just a software computer update, but i have a feeling they will not do it since my vin is not included in the recall. even though i experience the symptoms of the 2 brake recalls for the 2010 prius. thank you.

Tl* the contact owns a 2010 toyota prius. while driving approximately 60 mph, the vehicle stalled and could not be restarted. in addition, the check hybrid system warning indicator illuminated. the vehicle was towed to toyota of redlands (located at 921 new york st, redlands, ca 92374, (909) 793-0300) where it was diagnosed that the fuel gauge was inoperable, which caused the vehicle to stall. the vehicle was not repaired. the vehicle was repaired per nhtsa campaign number: 18v684000 (hybrid propulsion system) on february 27, 2019; however, the failure occurred. the manufacturer was not contacted. the approximate failure mileage was 200,000.

Just had recall work completed including software update. car now exhibits new limp mode behavior with low fuel. this never happened before the software update. trip meter indicated more than 50 miles remained with current fuel supply. fuel level was as two bars and low fuel light had not yet come on. limp mode occurred at speed on 4 lane freeway. vehicle would not restart and dash messaging indicated hybrid system failure. had vehicle towed only to realize it was all happening due to a low fuel level. i believe the safety recall software update has introduced agreater risk to my roadside safety and has made the vehicle less trustworthy and has reduced value.

The abs/brake light/ slip inidicator warning triangle on & off. my 2010 toyota prius ii has 153k mile. this has gone on/off for a few weeks now. the brake seems to loose the hydraulic power brake. i feel like the brakes have failed a few times while driving at higher speeds. i have to pump brake and vehicle begins to brake on 2nd pump. i've had to triple my stopping distance as to not rear anyone. i went to autoshop, they said it's the brake actuator/sensors that need to be replaced and it's expensive $2-3k. they said it need to be fix soon because brake might fail at any time. i called camelback toyota, phoenix, az, ed in service dept said there is no safety recall for this even though they know it has been a common problem with priuses . i checked vehicle repair history looks like abs programming was flashed back in 2/11/2010, when vehicle was still on the manufacturer, 3 miles. i have not fixed yet. please research this issue further for safety reasons. i do not want to kill anyone when brakes will eventually fail.

I purchased a 2010 toyota prius, within a month i had to replace the fuel pump sensor (after it went out on the highway and the car died while driving it). then 6 weeks after purchase i was driving down the highway again and the hood ripped up completely shattering the windshield while driving. i later learned both safety’s on the hood latch were broken and missing parts. it also has an oil leak that will cost me $2,200 to repair when i only paid $6,000 for the car on top of many other minor issues.

When the brakes are applied and going over a rough road surface, or pothole, the brake warning light appears, and the brakes suddenly stop functioning until back on a smooth road surface. this happens all of the time under these conditions. it is really scary when the vehicle suddenly loses all braking while trying to stop. i have a 2010 toyota prius and a 2012 toyota prius. they both have the same problem with the abs braking system. cannot understand why this is not a full recall on this potentially dangerous condition.

Sunroof exploded driving at highway speed on a clear night

Even though the breaks seem fine, the electric break system does work at all. all lights are on and the breaks pedals feels loose. when i push the breaks the vehicle keeps going. the abs warning light is on as well as all the other lights regarding to breaks and stability mechanisms.

Even though the break pads are new, the breaks are not working at all when vehicle is in motion. they do not feel tight. the vehicle looses stability in curves at a low speed ( slips) and keeps moving even when breaks are pushed to the end. all the break lights are on. there are several recalls regarding the breaks of this vehicle year 2010 and none applies to the vehicle vin number. it it not reliable at all in the highway. in order to brake the speed must be very slow and the distance must be way more than normal

All brake, abs, and traction control lights came on. checked abs code and received c1391. mechanic can here the actuator continuously running and believe the pump/actuator is bad. i have seen this recalled on 2010 made between march 2009, and october 2009. my manufacture date is sept 2010. vehicle was in motion when the lights came on. the car became hard to stop and regenerative braking is no longer working.

Tl* the contact owns a 2010 toyota prius. the contact stated that while driving at approximately 5 mph, the brake pedal was depressed but failed to operate. the vehicle crashed into the rear of another vehicle. a police report was filed. there were no injuries sustained. the vehicle was driven from the crash site to the residence. sunnyside toyota located at 27000 lorain rd, north olmsted, oh 44070, (440) 777-9911, was contacted and an appointment was scheduled to have the vehicle diagnosed which was still pending. the vehicle was not repaired. the contact stated that the failure was intermittent. the manufacturer was not contacted or notified of the failure. the approximate failure mileage was 93,000.

Loud screeching noise and vibration at brake pedal. abs brake and traction lights all lit up along with beeping. has happened sporadically over last 2 years. have owens car 5 yes. approx 120,000 miles. when the brake noise and all lights appear on dash very low braking ability. happens when driving or staring car. on 6/6 lights and braking failed and do not turn off. took to service at toyota dealer & tech says $3000 plus for repairs. possible leak in abs pump??

Car worked flawlessly and we maintained it regularly. took it in to address recall of jov update pwr mgmt ecu at dealer. dealer completed recall work. 2 days later engine lite check hybrid system and the ! on and triangle on. the car continued run but now was studdering when was not before the recall work. took it back to the dealer and he said we need a new hybrid battery. we believe the software update they did created a this issue. dealer acting ignorant and saying it needs new battery because of number of miles on car. asked for diagnostic print out from when they did recall work to they new diagnosis and they would not provide. we believe the recall update created a technical problem with our hybrid battery. we also believe that dealer not being honest regarding issues with this recall update and is using it as an opportunity to reduce liability for toyota on failed recall work and to use it as an opportunity to bring in large ticket sales repair ie they quoted us a new hybrid battery for 5,500.

Without warning, total failure of power assist to brakes. numerous dash warning lights and loud buzzer sounds. requires extreme brake pedal force to stop the car. extremely unnerving and dangerous situation.

Abs system completely failed while driving, no accident occurred but definitely could have. vehicle was taken to dealer and i was told there was a recall for the abs system on the vehicle but they declined fixing it free of charge due to mileage, and they gave me a quote of $3000 to fix a problem that they have not taken responsibility for a know about. to my understanding a recall is a recall regardless to mileage and i also asked the dealer about the problem 1 year ago and was told it was no problem.

Tl* the contact owns a 2010 toyota prius. each time the vehicle was driven, it shook, stalled, and the check engine warning indicator illuminated. in addition, the contact had to depress the brake pedal with excessive pressure for the brake lights to illuminate. also, the horn failed to function. the vehicle was taken to south bay toyota (located at 18416 s western ave, gardena, ca 90248, (310) 323-7800), but was not diagnosed or repaired. the vehicle was later taken to autonation toyota cerritos (located at 18700 studebaker rd, cerritos, ca 90703, (562) 802-4000), but was not diagnosed or repaired due to the repair fees. the vin was included in nhtsa campaign number: 18v684000 (hybrid propulsion system). the manufacturer was not notified of the failure. the approximate failure mileage was 100,000.

Headlight would burn out a year after replacement. manufacturer issued a variant of a recall intending to provide a fix for high rate of burnout. i took my car in to a dealership to receive the fix and the dealership caused a problem with the front windshield wiper apparatus. wipers would now work if the headlights were off, but would no longer work once the headlights were turned on. this would occur whether stationary or moving.

While the vehicle was in motion, the engine started shaking, the steering and brakes locked up and the engine ceased up as the car shut off. got error code p3190 for poor engine power, and then a day later everything was normal. this is the 2nd time this has happened while driving, the first time was in a 2002 prius.

Had to replace my head gasket

Tl* the contact owns a 2010 toyota prius. the contact received notification of nhtsa campaign number: 18v684000 (hybrid propulsion system). the contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. stevens creek toyota (4202 stevens creek blvd, san jose, ca 95129, (408) 984-1234) was contacted and confirmed that the parts were not available for the recall remedy. the manufacturer was not made aware of the failure. the contact had not experienced a failure. parts distribution disconnect.

It has been over 2 months and no remedy (software update) has been released for nhsta recall # 18v684 (hybrid system may shutdown and cause stall j0v). i am moving and need this issue fixed before i go overseas.

Brakes slip and lose grip while braking and traveling over moderate bumps or potholes, also happens while braking hard.

Tl* takata recall. the contact owns a 2010 toyota prius. the contact stated stated that nhtsa campaign number: 16v487000 (air bags) exceeded a reasonable amount of time for repair. the contact received the recall notification in the fall of 2017. the dealer (toyota of warren, 2657 niles cortland rd se, warren, oh 44484) stated that the parts were not available. the manufacturer was not contacted. the contact had not experienced a failure. parts distribution disconnect. *tt consumer stated as of 10/28/18 failed air bags has still not been fixed. updated 11/28/18*jb

While driving on the highway, service engine light came on, and car began to lose speed -- only permitting travel at about 50 mph. within a few minutes, the car shut off entirely. fortunately, was able to get to side of road but this could have been extremely dangerous due to lack of warning, and fact that was driving on a highway where others are going 60-70mph or faster. the inverter overheated and needed to be replaced. this issue was part of a recall, but did not include my year/car. extremely upsetting that toyota does not recall it or at a minimum send a warning to owners to have this looked at. this can cause potentially fatal accidents, and toyota seems to be aware of the issue.

Abs actuator failed while driving vehicle on high speed city street. loss of braking power noticed/observed. actuator failure has been confirmed by toyota dealer - car is currently being held for repair.

I recently noticed that when i open the car door to get into the car (with the engine off), the brake assist primes for quite a bit (> 30 seconds). then i start my car, i notice that the sound can be heard priming the brake (vacuum?) every 15 seconds or so and lasting about 3-5 seconds. it primes every time i release the brake pedal. the dealer said that the brake actuator is bad and will need to be replace or the car will not some in driving conditions.

Brake actuator keeps activating every 10 seconds. the cars abs, traction control, and brakes error lights have all come on. brakes are compromised in some manner which can pose serious safety issues while driving.

Abs and brake lights "turned on" on the dashboard while driving along freeway. had to push the brake pedal harder to stop the car. search online on what might be causing the warning lights, it was found out that so many toyota prius car owners were having the same issue. the symptom was caused by either faulty accumulator or master cylinder/actuator.

Tl* the contact owns a 2010 toyota prius. while driving various speeds for approximately 250 miles, the vehicle lost two quarts of oil. the vehicle was not taken to a dealer to be diagnosed or repaired. the manufacturer was not notified of the failure. the failure mileage was approximately 148,785.

On two occasions, june 22, 2018 and august 15, 2018 this vehicle suddenly accelerated while using cruise control and traveling at speed on generally flat, straight, 4 lane road in good weather. i have attached documents with summaries of each event and maps showing route and terrain during the events. hard braking slowed but did not stop the vehicle either time. both times, after traveling some distance while braking but continuing to accelerate without my foot on the accelerator, the vehicle made a thunking noise felt through the floor of the car and suddenly stopped accelerating. in the first incident this was after about 2 miles, the second time after about a mile. after each incident i phoned the local dealership and was told that if they could replicate the event they might be able to figure it out. i reported the events to corporate toyota and an investigation was opened. the vehicle was taken to fred anderson toyota of asheville where they spent several days with the car, interacting with toyota, who was asking them to explore and test various things related to the dual pedal fail safe, the computer, snapshots of events on the computer etc. their final judgement was that floor mats may have interfered, though it was the first thing i checked when i regained control of the car.

The brakes make sounds when pressed. look into the internet and prius chat forums and taking to local mechanic and found the brake actuator is faulty and need replacing asap.

Manufacturer recall number gou, is identified on your website as being part of the nhtsa recall number 16v487, recall status "recall incomplete"

I was driving to my house and the brake pedal went to the bottom. several lights appeared on the dashboard. i was driving in the highway and fortunately there was an exit and i could get out of the highway and i manage how to stop and i did not crash. the story could be another if i was driving faster. the next day i took it to the toyota dealer and they told me that the problem was the booster pump (attached you can find the estimate). i was shocked when i found how much was going to cost me. my car has never had a problem and all oil changes had been at the same toyota dealer. i have never taken the car anywhere else. investigating i found that this model prius 2010 in 2013 had a recall for this same problem affecting 82000 people. i am using the car with because i have to go out to work every day for the sustenance of my family and with a constant concern of having an accident and causing death to other people including myself, i need the help of toyota to pay for the entirety of arrangement i already spoke with toyota headquarters and they said that they will not help me with the cost of the repair, it is really expensive and it is not my fault. does toyota have to wait until there is an accident? or injury or dead people?.

Front driver and passenger seat belt did not buckle in-lock in, the mechanism is not broken, it't just not click to lock in.

Seat belt driver and passenger buckles inside latch worn out-locking pin worn out due to make out plastic. this is not a good safety seat belt oem. from manufacture toyota. we need to recall this. all seat belt buckle latch, inside materials to lock the pin should make out metal, not plastic... do to wear and used to snap in/out so manytime cause the buckles warnout. please recall this problems thank you.

I stated to the glendale toyota dealer in california that i hear and feel a buzz/click when i step on the brake and they informed me it is the brake actuator and warranty expired in december 2017. i am requesting is an extension to this warranty or voluntarily make it a safety recall. it is very dangerous and expensive to fix.

After changed all the 12v battery and 201v battery pack brand new. all the fluid; oil, cooling water, transmission also been changed new, even clean out the exhaust co2 deposit in the pipe, basically the engine been clean out like new. the problems now is not start or put into ready mode. due to the inverter and icu u1 circuit board now sending the signal to the dash board. dash board only show flashing engine light, push button show amber not green. i heard toyota is recal the software on the inverter, this is not going to help, due to reprogram the key and the imobolizer cause the infor on the dash to shut down, the obdii cant even read or function. now my 2010 hybrid is dead. i don't know what to do. please help.

Recall notice eoe was performed on my 2010 prius to correct an invertor problem. a software update was performed. according to my dealer at capistrano toyota as well as other dealers this was just a bandaid and not a true fix. the owner of capistrano toyota as well as other toyota dealers have written to toyota that the invertor needs to be replaced. the dealer h,s had many cars come back after the software fix and had to have the invertor changed. if the invertor fails while driving, the car can possibly just stop running or slow down to 15 miles. this will be very dangerous and possibly deadly.

Abs, brake and traction control lights on. code c1391 abnormal leak in accumulator.

Motor consumes excess oil. must add several quarts in between scheduled oil changes. occasionally when first started, the motor will stall or sputter.

I was aware the check engine light and alarm came on when i would make right or left hand turns. took my vehicle in for a check. was told there "was no oil on the dipstick" so had my oil changed on 2/21/2018 and my mileage was 72704. they did an oil consumption test at this time. when i returned at 73696 miles to have phase two of the test checked, the oil was at "full level". now at 77,250 miles and am having to add oil again. stopped at toyota service on 6/01/2018 for them to check the warning light. vehicle was low on oil again. they topped off the oil at no charge. thank you! when asked what else could be done about this problem, i was told i could replace the engine. not going to happen with my 2010 prius. not due for an oil change for quite some time. guess i will check and add oil as needed in the interim.

Every 4 to 6 months headlights are burning out.

C1391 - abs system failed

Brake actuator has failed. traction control, abs, brake lights illuminated on dash. more effort needed to engage brakes. this affects the regenerative braking as it no longer charges on braking as it was designed. checked toyota website for recalls since this is safety related, and there are none. which is quite disturbing. i’ve researched prius forums and this seems to be an ongoing problem. toyota issued a recall for the generation 2 model, however this seems to be a problem for generation 3 models as well. the problem did occur when on the highway traveling at 60 mph.

Tl* the contact owns a 2010 toyota prius. while the brake pedal was depressed, the vehicle delayed to stop and the brake warning indicator illuminated. the vehicle was taken to sheehy toyota of fredericksburg (3507 jefferson davis hwy, fredericksburg, va 22408, (540) 507-0076) and was informed that the vehicle was not included in a recall. the vehicle was not diagnosed or repaired. the contact referenced nhtsa campaign number: 13v235000 (service brakes). the manufacturer was notified and the contact was advised to contact the dealer. the failure mileage was approximately 250,000. *tt

Tl* the contact owns a 2010 toyota prius. the contact took the vehicle to toyota of west plains (1902 porter wagoner blvd, west plains, mo 65775) for a scheduled oil change before a road trip. upon returning from the road trip, it was discovered that there was no oil in the vehicle and the number two head cylinder was burned out. the vehicle was towed to the same dealer and repaired at the vehicle owner’s expense. after the repair, the ecu power management board malfunctioned and the dealer refused to reimburse the contact for the repairs. the manufacturer was contacted and informed the contact that there would be no reimbursement for the repairs because the recall had expired. the vin tool found no recalls for the vehicle. the recall information was not provided. the failure mileage was 111,226.

I had been driving the car and had experienced the loss of power described in recent articles as being an inverter problem (that was the subject of a software update by toyota that may not have fixed the issue). after experiencing this issue several times, my autobody shop recommended replacing the throttle body as the diagnostic codes were not 100% clear what the problem was. i have replaced the throttle body and not had the issue since, but i thought i would report this just in case this is related to the inverter issue. the issue i had was exactly as described -- driving the car, then suddenly losing power and practically unable to move the vehicle (i was able to drive it maybe 3 mph with no power steering, barely got out of an intersection in front of oncoming traffic one time it happened). this happened at various times, always while moving, both on the highway and on city streets, straight/turning. the only time it didn't seem to happen was when stationary. this is the article i read that compelled me to contact nthsa: https://www.cbsnews.com/news/california-dealership-refuses-to-sell-certain-toyota-prius-models-over-safety-issues/

Serious issue with the prius. brake actuator/brake booster fail. the braking is seriously compromised because of this problem. the dealership says it is known to toyota, but they will not offer any assistance. when the brake/abs/trac lights are reset the brakes function perfectly for a short period of time and then the lights/problem returns.

Three headlight bulbs have burned out requiring replacement before the odometer reached 70,000 miles. toyota sent a notice of a warranty enhancement program in 2017 on this issue, describing the proposed repair as the installation of "voltage adjustment wire harnesses." as instructed, i took my 2010 prius to a dealership on january 19, 2018 and was told that it required a repair, but the parts were not in stock and were on back order. in a follow up call to the dealership on april 26, 2016, the representative said the parts were still on back order, and there was no indication of when they might be received. the admittedly defective electrical system in my car can and has caused my headlights to burn out prematurely, which is an obvious safety problem. even though toyota recognizes the problem, they seem to be dragging their feet in correcting it.

Brake system has kept making air pushing sound but suddenly i cannot push the brake pedal at all. it feel like blocked. braking force is not working

The other day my brake light, traction, and abs light came on. took it to the mechanic and they said it's code c1391 - abnormal leak in the accumilator, electrical issue, and i must go to the dealer. i've seen others complain about this. shouldn't this be a recall?

Car loosing oil i add every 500 miles one liter of oil

A tire blew out on the highway, and afterwards the abs light, brake light, and traction light came on. apparently the brake acuator has failed completely.

Had recently purchased this vehicle used.. vehicle suddenly was powerless in the middle of the highway. struggled to coast to side of the road. barely being rear ended by traffic approaching from behind. over heated inverter replaced at no charge by toyota dealership. then dealership tried to tell me the car needed $5200 in additional work. i am in disbelieve i was able to purchase a car with out this work being done to it.

Tl* the contact owns a 2010 toyota prius. while driving at an unknown speed, an abnormally loud noise was heard and then the sun roof shattered. the glass exploded and imploded when the failure occurred. there were no injuries. the dealer (arlington toyota, 10939 atlantic blvd, jacksonville, fl 32225, (904) 302-9611) was notified and a diagnostic appointment was scheduled. the insurance company was also notified to inspect the vehicle. the manufacturer was notified of the failure. the failure mileage was not available. *tt contact states vehicle was traveling at 78mph and failure mileage was approximately 63,000. *tt

Driving on highway in moderate and heavy rain or snow affects the windshield shade and visibility to see the roadway clearly. the shade of the windshield is dull grey until driving on city streets or getting off the highway. car dealers had no answers or solutions in the past.

I own a 2010 toyota prius iv. i concur with all that has been documented about abs and braking issues with the prius. two weeks ago my brakes started to sqeal. i took it to a mechanic and was informed all was well (brake pads,fluids, oil). a week later the brake and abs indicator came on in my vehicle. the braking distance is elongated as i have to pressed firmly on the brake for the car to stop. i took it to my mechanic who reset the car. i drove from the mechanic and all appeared to be fine until i hit a bump in the road. the indicators came back on immediately and the braking changed. i had to pressed the brake pedal all the way down in order for the car to start. the car always surges forward whenever i hit a pothole, bump or any rough surface. in hin sight, when i first bought the car i had a fender bender because the car lurched forward when i was parking. i am now discovering this issue is a knwon issued with toyota; particularly the prius. fixing this problem seems to be expensive. toyota should cover the cost via a recall.

Antilock brake actuator and pump failure. quoted as a $4700 repair at dealer with labor. parts are just over $3600. there were recalls on gen 2 prius’and extended warranty on other prius’ . this car falls under no help at all. we are original owners and car had been essentially problem free. disgusted that this dangerous and known problem isn’t being properly addressed by toyota. all lights on dash related to brakes lit up while driving. still had brakes. took to dealer to check problem.

On a few occasions when the car is in motion, we have depressed the brakes and they did not grab right away. this happened once getting onto a highway, twice on a city street, and another time on a country road. there seems to be a small delay before they will grab, causing the car to feel out of control for that brief moment. it feels unsafe when this happens and doesn't seem normal. we contacted the service manager at toyota to have the car looked at, and he did not return our call.

I was driving down the highway, i hit the gas pedal to accelerate faster through a light that had just changed from green. as soon as i did that my car lost power and a bunch of emergency lights came on, i immediately got on the shoulder. no one was behind me otherwise i would've been in a wreck. i turned the car off and on again and the emergency lights were still there. i was able to drive up to about 10 miles an hour a few blocks to a parking lot. i had the car towed to the toyota dealership and they told me it was my inverter that over heated and needed to be replaced.

The car was moving when the traction light, abs light and brake lights all came on. thhe brakes felt a little different then. i could still brake but they were more stiff.

My car got stall on the road, it had a problem related with the hybred system. i took it to the toyota dealer and they said it was in a recall list. so they fixed but they damaged the suspension of my car and now they don’t want to fix it. my car is making a noise when i move the steering wheel and also when i brake. my car wasn’t making such noise before the stall on the road. i am frustrated with all this problems in my car.

Took prius in for coil replacement and was told the cooling fan was failing and there was a leak from the water pump. coolant level was not to the low point at anytime and was checked and refilled if not full, the temp warning has not come on. i am now being told that a head gasket is blown and that i need a new engine. the car is not even at 200k and has had all routine maintence and recalls completed.

Tl* the contact owns a 2010 toyota prius. the contact stated that the brakes made an abnormal noise and the brake pedal traveled to the floorboard when depressed. also, various warning indicators and gauges remained illuminated on the instrument panel. the contact had to apply force to the brake pedal due to the failure. the vehicle was excluded from nhtsa campaign number: 13v235000 (service brakes), although the vehicle exhibited the same failure as listed in the recall campaign. toyota of hollywood (6000 hollywood blvd, los angeles, ca 90028, (323) 498-2260) was notified and diagnosed that the brake actuator needed to be replaced. the vehicle was not repaired. the manufacturer was notified of the failure and excluded the vehicle from the brake system recall. the approximate failure mileage was 150,000.

Previously had no issues with low-beam lights. used in the morning- working fine. came out after work and both low-beam lights would not turn on. high-beam lights work fine. car was stationary and in park when lights were attempted to turn on. tried turning light switch and car off/on multiple times without success. had to drive home in the dark with high-beam lights.

Low beam headlights turn off/fail. i have replaced 7 low beam headlights in the past year, four in the past 2 months. in the two most recent cases both low beam headlights failed within minutes of each other while driving at night at highway speeds. i had a toyota dealer check the wiring harness per toyota warranty notice after the last outage and they stated nothing was wrong. when i had the lights checked by a different toyota dealer in jan 2019 they indicated the socket for the bulb was melted. bulbs have gone out under, wet, dry, hot, and cold conditions. the most recent outage occurred on march 8, 2019 while driving on the interstate..

Upon braking (exacerbated by wet or slippery conditions and hard braking) the abs system does not behave as expected. instead of pulsating to modulate the amount of braking force and slowing down the vehicle the brakes will completely stop engaging while the car travels a moderate distance (e.g. 10 feet) before the brakes kick in again.

Excessive oil consumption led to engine failure and replacement cost of approximately $5000.00 also excessive oil cost to constantly fill oil over the years. i purchased the vehicle new. and got stuck with it as i was going through divorce and not working it was unfortunately cheaper to pay for a used engine replacement through toyota. i have saved all receipts in hopes of recuperating money in the future

This vehicle has hybrid system faults recall since october 2018 and toyota still has not responded to my request to fix the car after 4months. it is very dangerous to drive this car because the hybrid system default warning light comes up pretty frequently.

When you turn headlights on the dashboard light go black can't see any things o it

Abs failed. warning lights do not appear. heard others have similar issue. toyota will fix the abs only if the warning lights appear. warning lights appear only when car is not on completely. brakes went out with no warning at all. brakes went out with no warning while driving. light bulb leaks moisture has since purchase. light bulbs blow frequently.

Electric steering makes the steering wheel hard to turn and is erratic. dealer said the car needs a new steering motor/column. car is not safe to drive. my research has found other model prius with silirar problems and also the rav4 has steering issues. this occurs while driving the car. my wife refused to drive the car. and i have parked it. dealer wants almost 3000$ to replace.

Vin # : (xxxx) on february 26, 2019, i asked autonation tyota buena park ( auto nation) to update the software and replace the invert assembly as per the recall notice letter from autonation. also, i explained that my car's inverter and engine coolant were replaced on november 19, 2015 with showing the invoice of dch toyota of simi valley and i had same overheating problem as before in summer 2018. on february 27, 2019, autonation emailed me as per the attached copy here that the toyota representative came to autonation and did not approve repair or replacement due to high mileage (218,542) of my car. on februry 28, i picked my car but i will drive after receipt of toyota's confirmation that vehicle is safe i believe that the inverter assembly should be replaced regardless of mileage for motor vehicle safety if my car has experienced inverter failure. also, i filed my complain with national traffic and motor vehicle safety department. regards (xxxx) parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6)

When i press brake on the bumped road, the car function weird and seems like it has sudden "shock" so it is kind of losing control for the car even i didn't press brake that hard, it happens several times already during the course of 7 years that i owned this car, even when car is new. i was so scared and nervous, i don't know where to report this problem and did mentioned to dealer before. the problem is random and unpredictable and i don't know when it will happen. but i guess i am kind of cautious on when i press pedal when i drive. this is mostly happen in local drive, not highway. in driving when driving forward, maybe there is something on the road, but it should not be doing this as it is very scary and it's like a sudden "jerky". my name is [xxx] it happened at least 10 times during the past 7 years to me. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

I had a sudden loss of power with a popping sound. the failure nearly caused an accident because i was turning into a traffic lane. this left me stalled in that lane of traffic. the failure turned out to be the inverter over heating was caused by the cooling pump in the inverter failing, which caused the inverter to overheat. this was not covered by warranty and was a very expensive repair. i chose not to have the dealer repair it at their extreme prices. i paid the dealer to diagnose the problem. then i had greentec in olathe ks. repair the system at 1/2 the cost that the dealer wanted

The vehicle was having issue with the steering locked up when turning with motion about 20+mph. the hybrid system is not as advertised the 50mpg in any way as it only gets average about 35mpg. the vehicle has 87000 miles and the old symptoms from second generation followed suit with it. the dash went totally off when weather is cold and suddenly turned back on when it gets warm. i had driven a few miles without the dash on and it was a bad experience since i cannot figure out the speed or what is going on. the steering is the major issue as we dare not to drive the car and the technicians from the dealer said nothing wrong with the vehicle but third party technicians recommend to take to toyota for recall.u turns are the worse that locked the steering and the car almost come to a stop with beeping alarms.

The car is consuming oil at unreasonable rates.

The headlights keep going out, making driving at night unsafe until you can get it fixed. it just happened again, march, 29, 2018. it happened 2/11, 6/11, 12/12, 1/13, 6/13, 3/15, 1/16, 7/17 and now. it wasn't raining, nothing interesting at all. local driving.

Tl* the contact owns a 2010 toyota prius. while driving various speeds, depressing the brake pedal to come to a stop, or when driving over a bump, the vehicle failed to stop. the contact stated that the vehicle stopped after a distance, but not when prompted. all the warning indicators illuminated on the instrument panel. the vehicle was taken to gullo toyota of conroe (45 s, conroe, tx 77304 ,(888) 483-0321) where it was diagnosed that the brake actuator assembly failed and needed to be replaced. the vehicle was not repaired due to the repair fees. the manufacturer informed the contact that the vin was not included in a recall and did not offer further assistance. the approximate failure mileage was 147,000.

As my wife was driving the brakes failed; the pedals went to the floor. she had to swerve to avoid hitting someone. she continue to press the pedals and the car eventually stopped. when i got to her i turned the car back on and tested the brakes. this time the pedals would barely go down and would only stop the vehicles if you went 5 to 10 mph. it rendered the car unusable. i found online that there was recall for 2010 toyota prius's but toyota said my vin wasn't listed in the recall for an actuator.

While driving on the highway, the instrument panel cluster on our 2010 prius went out and we were without a functioning speedometer or gas gauge for the remainder of the drive. this problem has happened to many other 2010 prius vehicles and toyota refuses to warranty this extremely costly repair, which causes many drivers to use their vehicles without a speedometer for extended periods of time.

My wife had a ‘near-death’ experience on 22-mar-18 while driving her prius (2010) back home. she was driving on a high speed interstate freeway (i-10) in houston and suddenly her abs brake system failed and she can she all warning lights in the dashboard (abs warning light, brake system warning light, slip indicator) were lit. as soon as she saw these warning, she tried to slow down the vehicle safely by applying brakes, but brakes were barely responsive. at this time, she was driving at a speed around 65 mph. she kept pressing the brake pedals and slowly moved towards the shoulder area. after traveling for some distance, the vehicle stopped eventually. she called tow truck and took the car to toyota dealership nearby. we are waiting for the response from the toyota service center about the fault.

Vsc, brake, and abs lights are on symptoms: cruise control will bump up the speed then "cancel" cruise control the ability to "set" cruise is rejected vsc, brake, abs lights turn on no regen braking brakes need way more effort to slow/stop abrupt braking will cause a skid any help will be appreciated.

Without warning, while traveling downhill at about 45 mph and braking, the car lost power and was very difficult to control. several dash warning lights came on. i was able to drive a short distance , at 10-15 mph, to the dealer for repairs. a transistor in the inverter had over-heated and failed. the event occurred on 28 jan 2017. toyota knew of this potential failure and recalled the car for a software fix (eoe recall ssc#eoe agg09a ), installed in the car on 29 april 2014, by dch toyota ( 2955 pacific coast highway, torrance , ca) also the dealer who repaired the failure. i only recently learned the recall and the failure were related and i believe the failure could repeat with potentially catastrophic results.

My emergency brake has failed. i park on a hil and my car almost went down without me in it , i was getting something out of the back seat when the eb failed, luckily the drivers door was open and i was able to jump in and brake with the normal brakes. also while braking and going over a bump my brakes fail for a second.

I just tested all years from 2010 to 2011 prius, those prius burns a lot of oil at every 2,000 miles. i did fill it (at 4.4 quarts of oil) correctly it but prius ate over 3 quarts in 2000 miles. like many of people have been reports this on priuschat.com and etc online forums. i hate to spend my money to buy motor oils! why this prius excessive oil consumption? "what did this happen?" i just purchased 2010 prius on oct. 2016. and i tested it. it still oil consumption. toyota dealer can't do anything for motor oil. since it happened, i still check oil level at every 2,000 miles and put it some motor oil in it until it reach to 5,000 miles for synthetic oil change.

While driving on highway at approximately 50mph, instrument cluster displayed brake, abs, (!), and tcs. as i attempted to slow down, brakes lost effectiveness and became mushy. i had to press on brake pedal extra hard to slow the car down and bring to car to a stop. pedal travel and force required was way more then normal.

My 2010 prius has relatively low mileage - approximately 44,000 miles. it has been routinely maintained at the dealership where it was purchased new. i just replaced the tires a couple of months ago, and the only issues have been the takata airbag recall & the need to replace air filters more frequently than may be normal because i do not have a garage so it is parked outside in a driveway where exposure to pollen & debris from trees is excessive. after a significant wind & rain storm wednesday night, the engine rattled & made unusual noises for several seconds when i started the car. then, the "check engine" light came on. i checked the manual, which said not to drive & to call a dealership immediately, which i did. i was told it was not safe to drive & it should be towed to the dealership. i waited until the following morning & started it again to verify the check engine light before having it towed. after i was at the dealership for 3 hours, the service guy told me that when he started it, the car run fine, the check engine light was off, & they were not sure what caused the problem, but their diagnostic evaluation showed a problem with an oil leak in the head gasket. i was quoted a cost of approx. $1500 to open it up, fix the leak, & check for any other problems. i gave the go-ahead, but am wondering if this is symptomatic of a greater problem that will be repeated. i am waiting to hear back from the dealership after the repair today. my goal is to drive the vehicle until it has 100,000 miles or so & then trade in for the newer model. did i make the right decision? do i have a lemon? is this a common problem with the 2010 model? is it reparable, or could the engine now be warped and irreparable?

My car completely shut down in traffic, engine, steering, transmission all quit and i was almost in a horrific accident as i could not control the car or get out of anyone’s way. the check hybrid warning light was also on. it was towed and the garage said it was a software update that i was not made aware of that caused complete failure.

Our prius has been losing power. it has 68k miles and we are the original owners. driving at hwy speeds we noticed we have to push hard down on the gas just to get the car to maintain highway speeds. hills are even worse. we are also still waiting on the parts to fix our headlights. over the years i have changed the low beam bulbs at least 6 times! when are the parts coming?

Copied the below from another complaint because this guy is having the exact same issue i am having, i bought the car aug 2017 right before the period to get it replaced expired, was never notified in any way of this warranty change so how am i supposed to know i have a defective part on my car.. but the dealership still sold it to me, now a month after the eligibility to get it repaired expires, my brakes die and toyota says they wont help nor is the dealership responsible for selling me the car without checking if the recalled part was replaced. they also keep mentioning the extended warranty on the actuator is only for "certain vin's". so they are gonna extend the warranty on certain 2010 prius' but not all of them.. this makes no sense.. please help my 2010 prius is having issues as same as the safety recall back in 2013 ( 13v-235 ). the abs light, vsc light, and brake light were on after a bumpy rooad in my neighborhood. i brought it to the dealer and they indicated that there was a leak in the accumulator. after reset the system, all the lights went off but i still feel the losses of pressure on the brake pedal. however, my car has 0 open recall and the dealer quoted me over 5k for the repair which is ridiculous compare to the value of the car.

Abs light stays on, i have no brakes when emergency braking, there was a toyota prius recall on brake master cylinder and booster pump but toyota said it was not for my vehicle. my problem is exactly the same problem as other prius brake recalls but toyota will not cover it. less then 65,000 miles on the car . how can a master cyl be bad by now, they usually last over 100,000 miles. very unsafe , and may kill someone. this should be covered by toyota with all the other brake recall problems with this year and model. i had to slam on my brakes but my car would not stop causing me to run into a wall at the baltimore harbor tunnel. this is a recall and letters were sent out by toyota about this faulty braking but now toyota will not honor the recall

My car need to replace the brake pump assembly which is same as one of their past recall in 2013. i called toyota and they said my car’s was not in the range so they don’t cover it. yea, certain vins but it is clearly that all the 2010 prius have this issue.

My 2010 prius is having issues as same as the safety recall back in 2013 ( 13v-235 ). the abs light, vsc light, and brake light were on after a bumpy rooad in my neighborhood. i brought it to the dealer and they indicated that there was a leak in the accumulator. after reset the system, all the lights went off but i still feel the losses of pressure on the brake pedal. however, my car has 0 open recall and the dealer quoted me over 5k for the repair which is ridiculous compare to the value of the car.

At about 125k miles, my prius nearly ran out of oil between services, and i religiously service my vehicle. i burned 1 to 2 quarts between services since. at 272,408 miles, i just paid $5751.59 for a complete engine rebuild... rest of car is in great shape. oil consumption problems were known by the dealerships, but i was given no recourse except dealing with it. latest issue..check engine light on, misfire on cylinders 1 and 4 (progressing to all), horrific knocking noise with sound of rushing water upon start-up. eventually, (once the cylinders fired significantly) the engine could run satisfactorily for the remainder of the drive... until the next start. early on i read that toyota knew of the under-engineered motor of the 2010s, but i have not received anything announcing a recall or care to fix their engineering issue. i have my service records to validate the care i've given to my car. the date of the engine rebuild is what i will provide as to when this happened, but the oil consumption began years ago.

When braking while car is going over a pothole, car will briefly accelerate forward before stopping.

Sometimes after starting the car, brakes will only response to hard braking. cannot brake to slow down gradually. brakes will not respond at all when lightly pressing down on brake pedal. only after driving about 1 mile will normal braking functionality return. this has been an issue ever since i first bought my car new.

Tl* the contact owns a 2010 toyota prius. while driving 65 mph, the vehicle stalled. the contact's spouse was able to pull the vehicle over safely. the contact's spouse turned the off and restarted the engine, and was able to drive home. all the warning indicators were illuminated on the instrument panel. the vehicle was towed to penske toyota of covina (1800 e garvey ave s, west covina, ca 91791, (626) 859-7400) to be repaired. the cause of the failure was not disclosed. the manufacturer was made aware of the failure and did not assist. the failure mileage was 27,000.

Toyota has performed what they purport to be the same recall, eoe, twice. the second time it was performed, it was performed without advance notice to me, and without explanation, except that it not been performed before on my vehicle, and was required. after the work was done, and after returning from the dealer, i checked my records, and i determined that the eoe recall had in fact been done three years earlier, in 2015. subsequent contacts with toyota and the dealers involved has not provided an explanation, regarding the need to essentially re-do the same eoe recall, except as a part of the latest recall, which currently has no remedy. this latest recall, nhtsa no. 18v-684, states “a previous safety recall may not have been fully completed . . . ”. the statement is vague, and no one has been able to tell me why any prior recall was not fully completed, when the service invoice indicates such recalls were in fact fully completed. toyota tells me other owners are affected, not just me. i have not received any notice from toyota, indicating the work done for the first eoe was in any way incomplete, such that it needed to be done twice. there is a possibility the second eoe installed different software, but i have no way of knowing, since the second eoe recall is being done in a non-transparent manner. this is a safety issue, because owners are not being made aware of possible problems with their vehicles, and it is unclear if the remedy has been properly vetted.

I have been experiencing the safety risks outlined in the following manufacturer recall number: j1v nhtsa recall number: 18v684 i have been dealing with this issue for the past 2 - 3 years and unknowingly may have been spending hundreds of dollars on repairs that may not have needed to be replaced. currently, my car is not running as i experienced a stall (11/09/2018) while exiting the freeway at a high speed with the screen reading "check hybrid system" and the dash lit up with the yellow triangle and exclamation point. i am not able to accelerate during the stall, brakes are working. this has happened to me countless times, almost always on the freeway or exiting and while traveling at a high speed. sometimes the vehicle would start back up after a few minutes of being turned off. this particular time (11/09/2018), i coasted the vehicle to a safe spot and the vehicle engine never turned on again. i towed the vehicle to my residence and then to my mechanic. i am only able to put the vehicle in neutral. the motor will not come on at all and the screen reads "check hybrid system". the car had over 1/4 tank of gas at the time. i currently use my vehicle for my livelihood doing independent delivery services such as instacart, doordash, postmates etc. since there is yet to be a remedy for this situation i want to know what my options are to get back the money i've spent or compensation for this vehicle since it is not usable and unable to be fixed by the manufacturer in a timely manner. i can provide documentation in regards to repairs made as well as visits to toyota in which they were unaware of the issue.

Tl* the contact owns a 2010 toyota prius. while driving 35 mph, the vehicle failed to stop when the brake pedal was depressed. the contact had to apply the emergency brake to stop the vehicle. the contact stated that the vehicle exhibited the same symptoms as listed in nhtsa campaign number: 13v235000 (service brakes). the vehicle was taken to toyota of poway (13631 poway rd, poway, ca 92064, 858-486-2900) to be diagnosed, but the failure could not be duplicated. the vehicle was not repaired. the manufacturer was notified of the failure and informed the contact they would send her a claim number. the failure mileage was approximately 137,450.

2010 toyota prius. consumer writes in regards to safety recall 18v-684. *ld the consumer stated the vehicle experienced a loss of power due to the faulty failsafe driving mode. the consumer no longer owns the vehicle. *js

There's a voluntary recall that toyota is doing on the prius right now that seems dangerous and poorly executed. the low beam headlight wiring harness has a defect that causes it to burn out headlights or short out in a way that the headlights won't work. sometimes you can get the headlights working again by wiggling the wiring harness, but i've had this occur several times while on back country roads and you just have 1 headlight, which seems super dangerous. toyota won't fix it unless you come in with the headlight busted which means you have to make an appointment and either drive the car around illegally with 1 working headlight or just not drive it for a week while you wait for your appointment. this is a safety defect and they need to replace the wiring harness without hoops to jump through.

Intermittently, several warning lights come on at once while driving: traction control, brake, and abs lights. while on, braking is lessened, brakes feel spongy, and the battery generation indicator shows no energy being produced. i found several similar complaints online. for me, the problem has comes and goes, affecting about 50 percent of my driving time.

Tl* the contact owns a 2010 toyota prius. while the brakes were engaged and the vehicle was stationary, a loud abnormal noise was heard from under the hood. the vehicle was taken to germain toyota of naples (13315 tamiami trail n, naples, fl 34110, (888) 722-4942) where the contact was informed that the master cylinder needed to be replaced and the linear off set value needed to be re-learned. the vehicle was not repaired. the manufacturer was not made aware of the failure. the failure mileage was 111,399.

My car is making a weird noise coming from the firewall. my traction control lights are on, brake, and a couple other. it turns off and then will turn back on.

I had not any problem with breaks at all....once after taking a left turn.......check pcs sytem with other lights like warning, slippary, abs, front breaks,came on. emergency lights keep flashing even if you shut the car off. i took off the fuse 16 for turn signals...everything came normal....only that i dont have turn signals. as soon as i put the turn signal fuse back...emergency lights started flashing and check pcs system with all other lights came on. dealer diagnosed the car for $ 150.00.....no clue....said they will charge me extra $550.00 to find problem.....on the second day evening they said i need to replace abs actuator will cost me $ 4500.00

Tl* the contact owns a 2010 toyota prius. while driving at 35 mph, the vehicle shook and smoke emitted through the vents of the vehicle coming from the engine. the contact coasted the vehicle over to the side of the road and powered off the engine. the vehicle was restarted, but the failure recurred. there was no warning indicator illuminated. the vehicle was towed to the contact's residence and later taken to an independent mechanic, but was not diagnosed or repaired. the contact received a recall notification for nhtsa campaign number: 18v684000 (hybrid propulsion system) and went to toyota of downtown la (located at 1901 s figueroa st, los angeles, ca 90007, (213) 354-9999) without the vehicle and was informed that the part was not available. the contact was informed that the part was not available for the repair. the manufacturer was notified of the failure and did not assist. the approximate failure mileage was 97,400.

I was exiting exit 3 of interstate 91 in new haven ct and was trying slow down and stop but when i applied the brakes there was no response. i pumped the pedal several times but the brakes still failed. i steered the car to the left to avoid directly colliding with the vehicle in front of me and wound up scraping it and crashing into into a barrier. i have since learned that this has been an ongoing problem with the 2010 prius and am outraged that the company has been willing to gamble with my safety and that of other prius owners. i do not have the ability to scan documents but the claim number is allstate 0523873875 and the ct state police incident report is 1800537795.

I am entering this complaint based on reading dozens of accounts that resemble my issue exactly. ten minutes into a forty minute drive three lights suddenly came on, the brake, abs and traction control lights. the brakes immediately became soft, requiring 50-60% more effort to stop the car and drastically reduced stopping time. this occurred on a dark county road, after a light snowfall and temperatures in the mid-20's. i quickly pulled into a church parking lot to check the brake fluid level and for any broken brake lines. i also shut off the car hoping to clear the error, which it did not. fluid levels looked normal and i decided to proceed the remaining 25 miles of my drive after ensuring that i could stop as needed. after 20 minutes of driving 45-55mph the lights turned off and braking power was instantly restored to 100%. i have not taken my car into the dealer yet, but plan on notifying them.

Tl* the contact owned a 2010 toyota prius. the contact stated that while driving at 25 mph, another vehicle crashed into the front passenger's side. the front driver's side air bags deployed as a result the contact sustained a leg injury. the contact was hospitalized and the driver for the other vehicle had unknown injuries. a police report was filed and the vehicle was towed to a tow yard. the vehicle was totaled by the contact's insurance company. the contact stated that she just received a recall letter number: 16v487000 (air bags) however, the accident occurred back in april of 2016. the dealer and manufacturer were not contacted. the failure mileage was 40,000.

Warning lights : abs , brake , and anti-skid come on and stay one. brake pedal is spongy and unresponsive. the error code reads out p1241 & c1391 which indicate brake booster pump failure. abs brakes have failed.

I find myself changing my headlights more frequently with the prius then any other car ive ever had. this is ridiculous and most definitely a safety issue. front lights are needed, i’d like to assume they put them there for safety, right? driving with hfh beams is just rude to oncoming traffic. double safety issue here.

I have a 2010 toyota prius, it overheated and the red light or the warning temperature light never turned on, so now i the car has a cracked cylinder head, that means i have to replace the engine.

Tl* the contact owns a 2010 toyota prius. while driving 55 mph, the park, abs, and vcs warning indicators illuminated and the brakes became difficult to maneuver. the contact had to depress the brake pedal several times to stop the vehicle. the contact stated that the vehicle exhibited the same symptoms as listed in tsb: 0079-18. the vehicle was not taken to a dealer to be diagnosed or repaired. the manufacturer was not notified of the failure. the failure mileage was approximately 100,000.

Park, abs, vcs, (!) warning lights on in dashboard. other symptoms - barking brakes and continuous pump whine, a cylcing electrical noise while parked. seems to be an issue with the actuator.

Brakes slip and lose grip while braking and traveling over moderate bumps or potholes, also happens while braking hard.

My vehicle abruptly slowed down on illinois highway 94 south bound at 33 exit at 2:00pm august 10. fortunately i was in right lane, which had a slight slope that allowed me to drive my car to the service lane. afterwards, i tried to start my car without any success. i called my car insurance agent on 2:11pm to tow my car to my mechanic. their diagnosis was a problem with the inverter/converter. my vehicle was towed again to the toyota dealer because this problem was in recall.

Vehicle has lost power on the freeway multiple times forcing me to pull over. in one instance i was almost rear ended by a semi. the vehicle will show a temperature warning and will then shut down and read, "check hybrid system". the toyota dealership claims it needs a new engine. this is a well known issue and will go in front of a judge in january. i have contacted toyota about this and they tell me it is out of warranty and not eligible for the warranty enhancement. this should have been an unlimited mileage recall but toyota refuses to do anything about it. this happened again this morning to my wife who was on a freeway where the speed limit is 70mph. this is an extremely dangerous error and i would hate to see someone die because their car stops on the freeway. this vehicle has also had severay p0401 codes, there is an warranty enhancement for this as well but limited to 150k miles. i was told by the toyota dealership it was also a culprit for a blown head gasket.

Brake pedal goes to floor. brake light is on. dealer says accumulator pump is bad. there is a recall for this item. they replaced it under recall in 2014 and refuse to do it again. quoted $2000 to repair. called toyota customer service and they won't do anything either. it is a safety issue and still having the same safety issues is not ok. i am 6 months pregnant and cannot afford to fix an item that should be covered for life of the vehicle due to this recall.

Toyota inverter failure. my specific vin wasn't included in the recall, but the ipm did fail, in the middle of the street, while driving, my car lost all power & went into limp home mode. fortunately the street wasn't busy & i wasn't struck by another vehicle as i had my 6 week old newborn in the car with me. i had dutifully checked to see if my car was involved in the recall & it wasn't, even though it failed. they only fix it after it fails, which is outrageous. someone is going to die when their prius loses all power while driving at highway speeds.

My prius was recalled to limit current in the main power inverter as they are failing. these inverters are still failing even after the software modification. toyota extended the warranty on the inverter as they know it could fail. i don’t want to be stranded before they will address the problem!

My brakes recently stopped working as they normally do (you had to press extremely hard on the pedal to get it to stop) and several lights came on the dashboard. prior to this the car was making a very strange noise when you start to push on the brakes. not like a typical squeaky brake sound. i took it to toyota and they gave me a quote for $3,700 stating that i needed a new brake cylinder assembly. i discovered a recall for 2010 prius for the exact diagnostic code and they said my prius was not covered by the recall. when you "reboot" the computer on the prius, the lights and brake problem go away. this appears to be a significant problem with the 2010 prius from what i have read on-line and toyota is not acknowledging it. it's also a very costly repair that seems to be easily fixed when you reboot the computer on the car. what is going on? how many people are paying toyota for this fix that appears to be a wide problem with the vehicle that should not be happening?

On 05/12/2018, the vehicle was in motion, merging onto the freeway, when the check engine light came on and the message "check hybrid system" was displayed. the vehicle was not driveable at normal street speeds and had to be towed off the freeway onramp. the vehicle was towed to a toyota dealership on 05/16/2018, where the diagnostic found that the inverter needed to be replaced. the diagnostic did not find any other fault codes. the inverter was replaced under warranty. then, 3 weeks after the completed repair (less than 200 miles), on 06/11/2018, the vehicle was stationary and idling when the check engine light came on and the message "check hybrid system" was displayed. the vehicle was towed to the same toyota dealership, where the diagnostic found that the fault code was with the hybrid battery this time, when it previously had not been an issue. after the code was cleared, the vehicle was 100% driveable and taken home while we consulted options for alternative repair or diagnostics.

After regular check-ups and maintenance at 90000 miles and 8 years of driving, all of a sudden three brake lights came on, the abs, hand brake, and skid control lights all came on. at this time the braking issues seem to be less responsive braking and slight jerking when putting constant pressure on the brakes at low speeds. when brought to the toyota dealership, they noted that there are no issues, however the master brake cylinder is likely to fail soon.

Tl* the contact owns a 2010 toyota prius. while driving 20 mph, several warning indicators illuminated. the vehicle was taken to an independent mechanic and was informed that there was a recall for similar vehicles per nhtsa campaign number: 13v235000 (service brakes). deluca toyota (1719 sw college rd, hwy 200, ocala, fl 34471, (352) 732-0770) was contacted and stated that the vehicle was not included in the recall. the vehicle was not diagnosed or repaired. the manufacturer was notified of the failure. the approximate failure mileage was 166,000.

I took my prius to the dealer because the brake light was on, to resolve the problem the dealer replaced my master cylinder and brake booster and brake booster pump assembly. i found that there is a recall for the 2010 prius. t-cp-dom date of issue july 1, 2013. the recall is for the same problem i had, i do not know why i am being excluded from the recall. please reply

Excess oil consumption, used 2 quarts of oil before next oil change, toyota’s don’t consume oil the way this car does , i’ve never owned a car with this problem using so much oil. the burnt oil is going to eventually build up causing more issues in the combustion chambers and smog devices .

Tl* the contact owns a 2010 toyota prius. while driving approximately 30 mph, the contact crashed into the preceding vehicle. the frontal air bags failed to deploy. a police report was filed and there were no injuries. the vehicle was not taken to the dealer for diagnostic testing. the manufacturer was notified of the failure. the vehicle was not repaired. the approximate failure mileage was 167,000.

The traction light, the abs light and the brake light appear on the dash. i have already paid the mechanic approximatly $1,500 for repairs and now i am told i need the abs brake booster which costs an additional $2,546.26. this part has been recalled on other 2010 toyota prius models, but not mine. i cannot afford this fix, so i am driving my car as it is. brake pedal acts differently each time i use the brakes.

I've counted at least 30 brake booster/actuator complaints on this site year to date for the same issue on this model year car. our issue is the same as everyone else. just under 150k miles, brake, abs and traction control lights came on my daughter's car (we are original owners) as she was driving home from work. non responsive brakes, only rear brakes engage if you push the pedal to the floor of the car. took to dealer who diagnosed dtc c1391, accumulator leak malfunction. our car was not included in original warranty enhancement (manufacture date of 1/2010), so price quoted was $4814.66. our daughter cannot afford, so we called toyota warranty who offered us $2007 as a measure of good will, but no more. this is a serious safety issue, beyond ridiculous that some cars with the same defect had the warranty enhancement program available which paid for the entire repair, yet most others like us were denied the fix and are facing astronomical repair bills that many cannot afford, nor anticipate on a car such as a toyota. the brakes failed while my 22 year old daughter was driving - that could have gone so very wrong.

While driving on a bumpy surface the brakes slip when applied. stopping ability is reduced. this happens on a regular basis, on surface streets and highways. i have noticed it while stopping in a straight line, but it may also happen while stopping on a curve.

I was on the freeway in traffic, going 60 mph. there was road construction coming up ahead. i depressed the brake pedal and nothing happened. the car didn’t slow down at all and i crashed into another vehicle. my car was manufactured when the “voluntary safety recall” by toyota was supposed to address this, but i received no notification, nor did thousand oaks toyota, where i had the car serviced, communicate about it. *js

Tl* the contact owns a 2010 toyota prius. while driving approximately 30 mph and depressing the brake pedal to slow down the vehicle, the pedal became loose. as a result, the vehicle continued moving and the anti-skid, brake, and abs warning indicators illuminated. the contact was able to bring the vehicle to a stop by depressing the brake pedal multiple times. the vehicle was taken to cavender toyota (5730 northwest loop 410, san antonio, tx 78238, (210) 681-6601) where it was diagnosed that the power booster failed and needed to be replaced. the vehicle was not repaired due to the repair fees. the manufacturer was notified and informed the contact that the vin was not included in any recalls; therefore, no further assistance was offered. the approximate failure mileage was 85,000.

I keep having to replace the low beam headlights in my 2010 toyota prius. what is going on? my commute to and from work everyday is 3 hours and with daylight savings time i am usually going to work in the dark or coming home in the dark. my lights went out on my way home in the dark once and i had to use my high beams to get home safe. i am sure this was blinding to oncoming traffic as indicated with all the flashing of high beams i got.

While driving our 2010 toyota prius ii on the interstate we began noticing a burning smell. then, the abs light illuminated on the dashboard. we pulled onto an off ramp and as we slowed the vehicle down smoke began coming from under the hood. we drove very slowly down the road and the smoke became more prevalent. we turned on a side street and my husband put the vehicle in park, got out, walked to the front, and noticed that the passenger front head lamp was melted and there was a flame. we quickly got our family out of the car (2 kids in carseats in the back). we moved away from the vehicle and the flames become larger and larger. we called 911 and the hood was engulfed in flames by the time the firefighters arrived. they were able to put the fire out quickly, so it did not spread into the front cabin or rear of the vehicle. we had not had any recent work done and the vehicle was fully operational until the time of the fire. we had not been experiencing any problems prior to this incident.

I took my prius to the dealer because the brake light was on, to resolve the problem they replaced my master cylinder and booster on my 2010 prius. i asked about a recall for the parts. i was told no recalls, i found that there is a recall for 2010 prius. t-cp-dom date of issue july 1, 2013. the recall is for the same problem i had

The vehicle was in a parking lot. upon starting the car, the dash displayed "check hybrid system" and the vehicle could not accelerate above 25 miles per hour.

At about 100,000 miles engine began using excessive amounts of oil, exceeding 1 quart per 1000 miles. toyota knows this is a problem, and even has a tsb on it: tsb 0168-16, yet refuses to take responsibility.

Tl* the contact owns a 2010 toyota prius. the contact stated that the vehicle made an abnormal pounding noise and the check engine indicator illuminated. additionally, the contact stated that the vehicle was linked to odometer fraud. the vehicle was taken to the local dealer (toyota of hollywood, 6000 hollywood blvd, hollywood, ca 90026), but the cause of the failure could not be duplicated. the vehicle was not diagnosed or repaired. the vehicle was taken to toyota of downtown la (1901 s figueroa st, los angeles, ca 90007) where it was diagnosed that the engine was misfiring and an engine compression test was needed to repair the vehicle. the vehicle was not repaired. the manufacturer was not notified. the failure mileage was 91,984.

My car had the abs warning light on and i heard a strange noise in the engine compartment. last year. on october 7, 2017, i was driving on the highway and another driver cut me off, so i had to break hard. the car pulled hard to one side and i hit the retaining wall. fortunately, the damage to the car was on the bumper cover only, and i was not injured, so i was able to continue driving. the dealer ran diagnostics on my car after the crash and reported i needed to have certain parts replaced. toyota safety recall 13v-235 describes exactly the symptoms my car shows and requires replacement of exactly the same parts. the only problem is that my car's vin does not fall in the range toyota reported in the recall. apart from that , the problem is the same. my accident could have been very serious had the retaining wall that stopped me not been there. i could have been in the center lanes and the story would have been very different, even with me surviving the accident.

Turning left after a stop sign on a single lane street (30 mph), suddenly the dash board started flashing 'stop car' warning and continues beeping. also, realized that applying break paddle did not help a bit. it was hard to press the paddle that moved a little bit. going straight about 300 ft. car reduced to idling speed. turning left into a parking lot of a school, i tried stopping it into a parking space. break did not work again. so, car stopped after hitting the curb. toyota dealership was called and arrangements were made to tow away car from school's parking lot. the car did not stop when towing person tried to reverse drive. somehow he managed to maneuver it on a tow truck. i was informed by dealership that break assist system (bas), built into prius hybrid model, failed. the system comprises of accumulator & pump that assists to stop the car when break paddle is pressed. though car was covered under warranty, break system and associated components were not covered. repair cost over $1900 to replace bas. purpose of this complaint to highlight nhtsa of the critical failure of prius design to allow break system to fail in such a colossal way. the car could not be stopped. this is a serious driving safety concern. any failure of break assist component should never ever take away this critical control. intent of this complaint is for the public safety, having toyota informed of the incident. it has been very disappointing that toyota has not given any response except giving a case number by a customer service center. request nhtsa to look into the incident and most importantly review design of break assist system for prius in the interest of public safety and defensive driving. please advise should nhtsa require further details or incident narrative.

The passenger air bag sensor is faulty. i see this problem exists in the recall history of this make and model. but i don't see a current recall for it now. what should i do?

This car uses alot of oil in general use. i put in 4 quarts about every 2 months

Engine loosing oil and i have to add oil every 5 days

I noticed a 'clicking' in my brakes and loss of pressure in nov. 2017. i took it to a mechanic friend to look it over and i was advised that it was the brake booster leaking and i should take it to the dealership because there had been a 'recall' sent on certain vin #s but mine wasn't listed on it. when i took it to the dealership they wanted to charge me $700+ to diagnose and 'fix' the issue. it was not on the recall list because of the production date of my car. i fought with toyota corp and they decided to cover the cost as a 'courtesy'. the clicking stopped for about 3 weeks then came back much louder and more frequently. still losing pressure, enough so that when i was sitting at a stop light i would put the car in 'park' to keep it from moving forward. again the dealership said this was not covered by the recall and this time the cost would be $4700+ to 'fix' the issue. this time they told me they confirmed the nitrogen leak with the 'bubble test' so it was, in fact, the brake booster, but it was still not covered. this time toyota said they would only pay $2000 for the total cost, again as a 'courtesy', but i would be responsible for the remaining amount. i asked the dealership if there was something i had done to cause this issue and i was told 'no'. to me then that is a defect from the manufacturer and i should not be responsible. i have maintained this vehicle with the dealership on a consistent basis, always taking it to them for oil changes, rotations, etc. always on the suggested time schedule.

On october 7, 2017 a driver cut me off on the highway, i pressed my brakes hard and the vehicle pulled to the side and i hit the retaining wall. the impact was not too hard and i was able to continue travelling. the abs warning light is on and i hear a strange humming noise under the hood. the dealer ran diagnostics and said i needed to replace two main parts in the brake system. i found a toyota safety recall 13v-235 affecting other prius 2010 that describes exactly the same problem and requires replacement of exactly the same parts indicated in the safety recall. the only problem is that toyota reported this problem in vehicles of the same year and model, but my car's vin was not included in their indicated range. thank you for your help

My car is a 2010 toyota prius with nearly 100k miles. i was traveling on the highway at approx 65 mph when another vehicle was trying to merge onto the highway. i usually maintain my speed but in this situation of traffic i slowed slightly and flashed my headlights for the driver to go ahead of me. the driver seemed to be unsure of merging safety and pulled over to the shoulder of the road. in that process i braked to slow and then accelerated in an effort to maintain speed with ongoing traffic. then oddly the acceleration went from under foot as if a “ghost” was pressing the accelerator pedal. at first i thought perhaps the floor mat was improperly pressing it. i pressed the brake a bit a few times and looked to the hazards to alert other vehicles but never pressed them instead intuitively trying to regain control of the car. the process of pressing the brakes and accelerator gently seemed to reset things. hard to say as most of my attention was focused on trying things to stop the accelerator. i just got lucky i think. i was able to regain control of the car within a short time that felt like a long time in retrospect. perhaps a moment or two that felt like longer. i did not see indicating lights on my dashboard and they may have lit up- i was doing my best to notice cars around me and maintain control of the vehicle. my car has been “fine” since but i have not gone back on the freeway. i have not returned to the toyota dealership but thought about going today. i’ll wait to hear back in case there are specific instructions i should follow for that to help. i looked once stopped and the floor mat is nowhere near anything that could catch a petal. weather clear on the evening of feb 1 approx 6 pm medford oregon on northbound i-5

There is a clicking sound when you move the steering wheel back and forth when car is stationary, sound is coming from the steering shaft connection to the rack and pinion. same clicking sound when car drives over bumps in the road. previous recall of this problem for 2004 to 2009 prius model stated a defective intermediate shaft. this problem sounds identical to the recalls of 2004-2009 prius models.

Drivers’s side headlight and high beam light going out at same time. headlight bulbs on both sides were changed out in november 2016 (a little more than a year ago) and i only have a 10 mile commute to work. in november of 2016 driver’s side light was also the one that burned out.

Reference: toyota prius brake booster pump assembly recall 2013 the 2013 recall was issued for approximately 82,000 prius vehicles manufactured from march 2009 to october 2009. the car i own and operate, according to a toyota representative, was built in december 2009 -- thus, i presume, did not fit within parameters of this particular recall. a toyota customer service representative said that the vehicle matching my vin number has no safety recalls associated with it. however, the same issue referenced in the recall -- a faulty brake pressure accumulator that compromises the brake booster pump assembly system -- appears to have surfaced in my 2010 prius. no accident has occurred. the vehicle is indicating a problem via its dashboard warning lights. a toyota maintenance technician, on sept 21, 2017, diagnosed that the car's brake accumulator pump is malfunctioning -- and that it needed to be replaced. i am petitioning for consideration to expand the 2013 recall, which was ordered to correct a design/manufacturing defect. the same flaw is present in my vehicle (even though my vehicle was not covered by the original recall).

Approaching a stop the brake pedal in the prius will suddenly lose resistance and will need to be pushed to the floor where the brakes will finally engage and the auto will come to a hard stop. this happens randomly and is difficult for a mechanic to duplicate. i took the vehicle to a trusted mechanic (not the toyota dealership) and he confirmed it is an hydraulic problem and that pads/drums/etc. are ok. a recall was issued for 2010 prius’s describing this exact situation but my vin number was not included in this recall. recall details the brake booster pump contains a compartment filled with nitrogen gas. this nitrogen gas can leak into the brake fluid causing reduced hydraulic pressure during application of the brakes. reduced braking efficiency can increase the risk of a crash. dealers will replace the brake booster pump assembly as necessary to correct this concern. our quick take reduced braking performance may be experienced due to a brake booster system issue. what should you do? toyota will begin notifying owners of the affected vehicles during july, 2013. if you notice problems with the braking system, or you don't receive notification and you feel you should have, please contact your dealer for further instruction. they may ask for your vehicle identification number (vin), so please have it handy when you call. on jan 16, 2018 i called my local toyota service department and was told nothing could be done as i have no outstanding recalls on the vehicle. i then called toyota on jan 17 and they told me much the same and opened a case number for the issue. this issue seems to be covered on nhtsa number 13v235000. i am requesting nhtsa advice as to how to proceed.

Brake lights came on while driving on freeway. power brakes seemed to fail and a large amount of pressure was required to stop vehicle. toyota of fort worth dealership diagnosed that the actuator needed to be replaced. we performed repair (at a cost of roughly $2,000.) a few days later on a longer drive the brake lights turned back on. we returned it to the dealership and were told that the brake booster/master cylinder assembly needed to be replaced at an additional cost of $2,900. i notice that toyota had a recall for this part on other 2010 prius vehicles but my vehicle is not included in that recall.

I was driving to my house and the brake pedal went to the bottom. several lights appeared on the dashboard. i was driving in the highway and fortunately there was an exit and i could get out of the highway and i manage how to stop and i did not crash. the story could be another if i was driving faster. the next day i took it to the toyota dealer and they told me that the problem was the booster pump (attached you can find the estimate). i was shocked when i found how much was going to cost me. my car has never had a problem and all oil changes had been at the same toyota dealer. i have never taken the car anywhere else. investigating i found that this model prius 2010 in 2013 had a recall for this same problem affecting 82000 people. unfortunately, the vin number of my vehicle is not in this range that reaches a0067875 and mine is a0205005. i need for toyota to extend the recall range because the problem is exactly the same and also help me to cover the cost of the repair. at this moment, my car is parked at home because is not drivable. i already spoke with toyota headquarters and they said that they will not help me with the cost of the repair, it is really expensive and it is not my fault. does toyota have to wait until there is an accident? or injury or dead people?

Car in two accidents over two years body was not properly welded back to the frame! brakes were not properly realigned neither was the steering column transmission bands were not operating and would not shift and numerous other parts for leakage from brake lines to transmission lines all lines were broken and so are the seals on them!

My 2010 prius has had lights come up on the dashboard. vsc, brake, traction & abs. after the local toyota dealership ran diagnostics, it came to light that the brake assembly with accumulator will need to be replaced for near $5,000. it would seem that this is a common problem that has resulted in a recall for only some of the 2010 prius models. mine was not one of these recalled. i would like to request recognition that this should be covered under the same recall. toyota is a good product, and i understand that recalls are just a part of life. as it stands, my regenerative braking no longer works and i have been informed that i will lose all braking eventually.

Leak of nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. under certain circumstances, this condition could affect stopping distance and increase the risk of a crash.

Tl* the contact owns a 2010 toyota prius. the contact stated that the vehicle experienced a loss of engine power. the check hybrid system warning indicator illuminated. the vehicle was towed to toyota of greenville located at 2686 laurens rd, greenville, sc where it was diagnosed as an ipm failure and the inverter would need to be replaced. the contact referenced nhtsa campaign number: 14v053000 (hybrid propulsion system, electrical system) however the dealer informed the contact the vin was not included. the vehicle was not repaired. the manufacturer was not notified of the failure. the failure mileage was approximately 132,000.

Airbag light started turning on every so often. after recall work at dealer, it went away, but again now holds constant.

I took my 2010 prius in for airbag work & they asked how long i had been driving w/ my brake warning lights on. they had not been on prior to then. they hooked up a computer & showed me that the vehicle had been started 31 times since the warning was 1st detected. they said there was most likely a leak in the brake booster system. they reset the warning, i drove for a day & it came back on again while driving after about 10 starts. after the warning lights came on again, i noted an immediate & significant change in braking responsiveness & vehicle control...started pulling to the right. this was on the highway while driving straight. i took the car in to a local toyota dealer for full diagnostic & they said that they're were unable to locate the exact leak location, but that their tech order shows to just replace the booster which will cost about $3,300 o replace.

Vehicle shakes for about 30 to 45 seconds and produce a foul smell inside the cabin it happens off and on and dealer refuse to fix the problem.

We were driving on the highway at about 70 miles per hour when the reading lights and dashboard flashed on and then off in a matter of about 5 seconds. the dash showed a triangle indicator light with an exclamation point. the dash also seemed to reset and showed the display as is the car had just been turned on. this incident happened twice within a 4 hour period. once on the highway and once on a back road going about 40 mph. the car did not stop either time, but it is still concerning.

Exiting off freeway at s. main in walnut creek california at appx 45mph both headlights went out at the same time. could not be turned on. interior headlight indicator remained on but headlights remained off. highbeams worked.

Engine burning excessive amount of oil. car has been regularly serviced. last night, i noticed that the oil reservoir level was so low, the dip stick did not even register it. i had to add 2.5 quarts of oil before it started reading the oil level again.

Driving down the road when the brakes went out. warranty coverage from toyota on the same model, make, and year for this problem. my vin not included in this coverage. the brake accuator assy is the issue. high dollar repair!!
