2010 TOYOTA PRIUS Complaints

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.

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.

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 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.
