Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I lost power on overpass. Hybrid malfunction light, collision light, engine light all came on. Almost matching recall, but Toyota service told me it's a module and would cost 1200$ to fix. I told them no. Charged me 144$ and I erased code, with no problem since? Toyota does not care and I complained?”

“Toyota has a very well known issue with head gasket failures right around 140k miles that they refuse to address. This is my second Prius and my second failure right at 140k miles. They refuse to acknowledge it, but the advisors in the service department say that's their bread and butter. They repair bad head gaskets on priuses for $5k all day long. Toyota needs to do right by their clients.”

“In the 2017 Prius Prime when the car switches from Electric power to gas the car frequently fails to allow you to accelerate. It is like you are stuck in neutral on the freeway, taking your foot off of the acceleration pedal and pushing it down doesn't always fix the issue. The accelerator foot pedal can be completely down to the floorboard as you are losing speed. The safety issue is that you are losing speed, and on the freeway and the car doesn't recover losing some control. …”
