This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
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.
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.
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.
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.
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. Looking into this issue further it is an extremely common issue and should be a recall item.
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.
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.
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 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.
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 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.
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.
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 )
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
