2015 Toyota Prius C Complaints

Car feels like it lunges forward while braking over bumps. I have learned this is a known manufacture defect with the Brake Booster and Brake Actuator which Toyota is refusing to replace outside of 10 years from manufacture date. This is a critical safety item and failure can result in loss of brake power. Most owners do not know this part even exists until failure has happened already.

Bad break booster and was told I can’t get it repaired under the replacement program because it has to many miles! However I purchased my 2015 Prius used that had over 100 K already never received no notice from manufacturer or the dealer I bought the car from this is not fair and if Toyota is putting in faulty brake boosters, they should be replaced for free regardless of the mileage because I didn’t break the booster It’s the brake booster that was originally installed by the manufacturer! Someone needs to do something, especially if it’s not the car owner‘s fault It’s the manufacturer fault for installing faulty parts! I need my car as a single mother I can’t afford $2000 for repairs and labor

The ABS and traction light appeared on the dash while driving on the freeway. I attempted to brake, while merging to exit but the car brake system did not respond. Luckily there were no cars close to us. Figured it could be a brake fluid problem so I added more fluid and it went away for a bit. It’s come back again and my car feels unsafe to drive. The brake pedal feels stiff or sometimes mushy like dough. I am waiting to get a diagnosis on my car but from what I’ve read and what other prius owners are reporting, it appears to be the “break actuator and break booster pump” that is failing to work properly. Wondering if any other Prius owners have filed a complaint.

I was driving down the road when I noticed my brakes were not working. I had to push a lot harder on the pedal to slow the car down luckily, I did not crash into the car in front of me. I pulled over to see numerous lights on the dash such as traction, abs, and brakes. I had the car towed to Toyota where they quoted me almost $3000 to fix the brake accumulator and booster assembly. They said my car is outside the extended warranty of this problem. My car is a 2015 Prius with 154k miles. I found online that these things fail commonly on this generation of Prius. It's horrible for this company to charge us basically the cost of the car to fix the brakes.
