2011 TOYOTA PRIUS Complaints

The contact owns a 2011 Toyota Prius. The contact stated while driving 25 MPH, the ABS warning light illuminated on the instrument panel and the vehicle failed to brake normally. The vehicle was taken to the dealer and the contact was informed that the brake accumulator and brake pump needed to be replaced. The vehicle was not repaired. The vehicle was not under warranty. The manufacturer was not contacted. The failure mileage was 156,000. The VIN was not available.

ON Sept 9th, 2022, I was involved in a collision, traveling approximately 30 - 40 MPH and struck a vehicle that pulled into my path. I struck the other vehicle perpendicularly (T-Boned). My vehicle impacted on the front, initially, and then on the driver's side at full force. The result of the accident caused the front bumper to be damaged and the entire left side of the car was crushed. The force of the accident caused the driver's window and port-hole to shatter. The AIR BAGS DID NOT DEPLOY. None of the air bags deployed. The vehicle is still in the auto repair lot and has yet to be inspected by anyone. There we NO prior indicators of any problems with the airbag system.

The contact owns a 2011 Toyota Prius. The contact stated that extra effort was needed to stop the vehicle due to the brake pedal being depressed to the floorboard. The contact stated that the traction control, ABS, and brake warning lights would appear upon starting the vehicle. The contact had taken the vehicle to an independent mechanic where the vehicle was diagnosed with a defective ABS actuator control unit and the contact was provided an estimate for the repair. Neither the dealer nor the manufacturer had been notified of the failure. The vehicle was not repaired. The failure mileage was approximately 133,000.

The contact owns a 2011 Toyota Prius. The contact stated when his wife turned on the vehicle the brake, abs, and traction warning lights illuminated on the instrument panel. The contact stated while she was driving at 10 MPH, she noticed that the brake did not have pressure as usual. The vehicle was diagnosed at an AutoZone, and they stated that there was an abnormal ACC (C1391). The manufacturer was contacted, and they stated that the vehicle was out of warranty. The failure mileage was 178,000.

This issue started happening intermittently beginning in April 2022. The ABS/Traction Control/Emergency brake lights came on all at once and the car lost power braking ability. The car would stop, but it required much more force on the pedal and an increase braking distance. Folsom Lake Toyota Service said that there wasn't anything they could do if the warning lights had turned off and to try to recreate the issue. It happened again in May 2022 while my daughter was driving the car back from Tahoe. She was not hurt, she avoided an accident. The car returned to normal operation after it was parked for one day. It happened again in July of 2022. This time the brakes hissed when applied. Called Folsom Lake Toyota to have it looked at. They diagnosed it as error code C1391 and the master cylinder (acctuator) and brake booster needed to be replaced. The repair was $3200, so we took the car to Roseville Toyota for a second opinion. Roseville Toyota was able to recreate the issue and the brakes completely failed at their service center. Their estimate was for the same $3200 repair. We called Toyota Corporate and they responded that there was a Toyota Customer Support Bulletin ZJB sent out for this issue. The bulletin extended the factory warranty on the parts for 10 years or 150,000 miles. The bulletin describes the exact code and symptoms our car experienced. Our car is 11.5 years old and 113,000 miles. In speaking with Toyota Corporate, their position is that they already extended the factory warranty once and since that our car is past the 10 years, they refuse to consider my complaint or provide any "goodwill" assistance with the repairs. Toyota knows there is an issue with their master cylinder and brake booster parts. They set an arbitrary warranty extension date rather than recalling the cars. Toyota is waiting for the brakes to fail BEFORE they fix the problems. My daughter could have been seriously injured or killed, or she could have killed someone else.

safety brake booster and actuator concern. the car abs, master cylinder brake lights are on. the booster is making hissing air sounds and the brake pedal vibrates. the code is 1309 maybe more.. this is a problem with thousands of prius and costs thousands to repair. Toyota extended this warranty to 10 years 150k mine 2011 so lost the repair last year but only has 150k miles.

My brake accumulator pump has begun running much more frequently than it should. Upon extensive online searching, I learned that this condition is warning sign of an eventual failure of the brake booster pump and/or master cylinder which will cause brake failure at an unpredictable time when the brakes are applied. I understand that this condition is known by Toyota and has been addressed by "warranty enhancement ZJB". However, my car is outside of the cutoff age/mileage. The president of Capistrano Toyota in Southern California made this problem known to you with an urgent letter dated 9/19/19 and expressed why this NEEDS to be a recall issue, not just what it is now. The reason is because not only has Toyota time limited repair coverage, they would not do the repair until failure occurred....a totally illogical and dangerous plan. I should not have to pay ~$3000 to have this well-known problem repaired at my own expense just because the invitable failure hasn't happened yet, and I'm not within Toyota's arbitrary time limits for having the repair covered at no cost. The symptoms I am experiencing are precisely those that are the precursor to this known failure. Why has NHTSA not acted to force this issue to be a full recall? You are putting lives at risk by not acting in a timely fashion given the Toyota dealer's warning I mentioned above.

While driving at roughly 58mph, while going around a turn: multiple dashboard lights came on, Tire pressure, traction control, emergency brake, one other. My brakes became less responsive (roughly half braking strength). This is consistent with the pseudo recall offered by Toyota covering my vehicle for a limited time, for which no notice was given and no warnings were sent.this issue has caused over five dozen crashes and during the duration of the recall, vehicles were not eligible until the braking system had failed. There were no signs of the faulty part until after the extended warranty period had expired, but the issue is the warrantied part, and the failure is consistent with the failure caused by the manufacturing defect responsible for the extended warranty effective in 2017

All brake lights came on while driving on freeway Abs, traction control, and Brake light Pulled over and brake pedal felt different, not as sensitive to braking as usual. Toyota dealer said code c1391, brake booser Internal leak

Multiple brake warning lights came on at once. Took to dealership and was told Brake Booster Pump had failed requiring replacement of parts totaling in over $3,000 in cost. Attached is a class action lawsuit about this exact issue, as well as a Toyota Customer Service Bulletin acknowledging that they knew about the issue years ago.
