“I was driving on the interstate when my car's hybrid system warning lights a came on , and the car slowed to a crawl. Luckily I was in the right lane and was able to pull off on the shoulder of the road. The car competely shut down. I've had it towed to two Toyota dearlships, (the same one twice),where I was told a number of different things. First, I was told there was water in the gas tank. There was no way that was true, since I had already driven 3/4's of a tank of gas, and I always fill my tank up. I refused to have a new fuel system put in to the tune of $2500. …”

NHTSA complaint #11676437, filed 2025-07“When I looked up my car on Kelly Blue Book for pricing, it said that it has been recalled as of 2020. I was not aware of this at all and could have got into a serious accident. I recently purchased a 2015 Toyota Prius Hybrid in February and not even my saleswoman told me that it has been recalled. It has a sleuth of issues that came with it.”
NHTSA complaint #11418762, filed 2021-05“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. …”
