2015 Toyota Prius problems

“The brake booster pump has malfunctioned, exactly 1 year outside of the secondary coverage supplied in the voluntary customer support program for this exact issue, despite being under 150,000 miles. Now the car is unsafe to drive since the brakes are malfunctioning.”

“Pulling out of a parking stall, when put vehicle in drive, the engine revved up and accelerated - vehicle crashed, the brakes did not work- there was skid marks. Floor mats are factory OEM were installed properly. I did not hit the accelerator and I am in good health and mind. I have driving for over 30 years, never had and accident nor a ticket! - A county officer was at the seen and left me with vehicle that had to be towed away. The Vehicle is a total loss. I have insurance but felt that this incident need to be reported, There is no safety recalls and the vehicle was always property maintained”

“My mom was involved in an accident in her 2015 Toyota Prius on April 19, 2022, which she advised lurched forward at a stop and when applying the brakes to stop the vehicle, she said was unresponsive, causing her to clip a vehicle and sending her vehicle into a ditch totaling her car and injuring her passenger and her. I would like to have this investigated and hold Toyota responsible. This could have been much worse and lives could have been lost. She is now without means of transportation, and she is now possibly responsible for damages to property and bodily injury because of this. Through my research I have discovered multiple class action lawsuits brought against Toyota for the same exact models. I asked the police officer to run a scan on the computer, but he advised it was only for serious accidents. There was no indication of the problem or messages.”

“I was driving from Las Vegas to my home in Los Angeles. An alarming message began flashing on the dashboard telling me to pull over. The vehicle became hard to control. I somehow managed to get it off an exit. I was "lucky" enough to get it towed to a nearby Toyota dealership where I was told the inverter had failed and that that inverter and associated parts had to be replaced. On my 2015 Prius with only 50,000 miles on it. I SPECIFICALLY asked if there had been a recall on the electrical system of any 2015 Priuses, and they flatly said no. I also CALLED TOYOTA, and they also said there were no recalls involving the electrical system or inverters. The Barstow Toyota dealership said it would cost over $5,000 to repair AND that they wouldn't have the parts they needed for a WEEK. As it was, I had been stranded in the desert at a hotel for two days. I then had to pay $1,100 to be towed back to LA and took it to a hybrid mechanic I trust and paid them to do the work. But this cost me THOUSANDS UPON THOUSANDS. In a month where a friend of mine died (which was the reason I was driving from city to city). To have to replace this on a car with only 50,000 miles is…”

“Code DTC C1391 - Abnormal leak of accumulator pressure. Internal failure of the brake booster pump assembly, preventing the system from maintaining proper hydraulic pressure. This means the brakes don't work, putting the driver's and passengers' lives at risk. This DTC C1391 code and problem were reproduced and confirmed by an independent service center who specializes in 3rd generation priuses. There were warning lights that lit up when the brakes failed - the ABS, traction control, and brake light all lit up but only after the brakes had stopped working. This is a known manufacturer defect but toyota won't pay to fix it because they put a 10 year limit on first driven date or 150,000 miles. This prius only has 100k miles but toyota still won't stand behind their product even though they have admitted it was a manufacturing defect and they sold a defective product.”

“The headlight bulbs keep going out. I have replaced the bulbs at least 2-3 times a year for the past few years. I have asked dealers about this and they tell me there is no recall or tsb. This is a hazard to night driving because of decreased illumination, especially in dark roads with not enough lighting. Please recall/fix this issue!!”
