2012 TOYOTA PRIUS Complaints

Was 8 days out of warranty so Toyota would not honor offer to replace the brake booster/actuator. Paid personally to have it done with genuine Toyota parts. 16 months later same parts need replacing. Toyota refuses to help.

Brake booster has gone out. This is a known, dangerous issue that Toyota knows will occur, It is a dangerous and expensive risk to those driving these ticking time bombs, and those potentially in the path of these vehicles. This is a pure safety risk item. No one asking for these brake actions are gaining anything materially other than the use of their cars safely. To make matters worse, Toyota doesn’t even make these in volumes that don’t generate volume pricing efficiency, meaning replacement runs upward of $4k to $5k at their dealerships to replace. Criminal…. Please help.

On February 27 2024 I had spend 2300 dollars on car repairs see enclosed then on April 11 2024 while backing out of my driveway, I experienced a sudden acceleration of my vehicle which led to body damage to my car yet Toyota after inspection says that now the car system works perfectly. Prior to this incident I experienced warning light and windshield wiper malfunction .

Brake system warning lights illuminated. The brake pedal pressure required to stop the vehicle has increased. In effect: no power brakes, no traction control, and no antilock available. Intermittent engagement of an electric motor can be heard about every 8 seconds for a period of about 3 seconds during operation of the vehicle at all times.

The contact owns a 2012 Toyota Prius V. The contact stated while driving at an undisclosed speed, the temperature gauge and check engine warning lights illuminated. The vehicle then stalled. The vehicle was able to be restarted. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 190,000.

Sudden lights appear on dashboard. Brake system sudden fail becomes very hard to press the pedal or apply brakes My car has 136000 miles only Asked mechanic and mentioned the brake booster pump.

I was driving when I felt my brake pedal start to become soft and mushy. I was able to brake, but I had to pump the brakes to get full brakes to stop. I also noticed warnings began to appear on my dashboard. The warnings that were shown are the brake light, traction assistant light, and ABS light. I took it to Gates Toyota in South Bend, IN and paid for a brake inspection. They told me that my brakes themselves were OK (pads, rotors, calipers), but they were getting a C1391 error. I was told that the brake accumulator has an internal leak. I was told that I needed to replace the brake master cylinder and brake booster pump assembly. I bought the car used from the dealership about a year and a half ago. After doing research, I found that this same issue has been a common recall problem on a number of Toyota vehicles starting as far back as 2008. I also found a few class action lawsuits concerning Toyota vehicles with the exact same issue. My vehicle doesn't show any current recalls, but I'm having the same problem as other Prius V vehicles are having. I was quoted $3300 to fix this problem. I shouldn't have to be responsible for paying for a defect that has been recalled on a very large number of vehicles, and also has been the result of class action lawsuits.

The contact owns a 2012 Toyota Prius Plug-in Hybrid. The contact stated that while driving down a winding road, the brake warning light and brake message suddenly activated and while depressing the brake pedal, the pedal extended to the floorboard and the vehicle would not immediately stop. The vehicle was later taken to the local service center who diagnosed that the brake booster, brake master cylinder, and brake booster pump assembly were faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The contact was informed that the vehicle did not qualify for the manufacturers extended coverage regarding the failure. The failure mileage was 130,000.

Brake pressure actuator defect leading to major brake failure. No warning until it's too late.

Warning lights, and while driving the ABS, brake, and traction control lights came on, and I NOTICED a strange sound when applying the brakes. The brakes seem somewhat soft when applied. This is a 2012 Prius with 123,000 miles.
