“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.”
