Example complaints

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

“Since I have owned the car, slightly over a year, when decelerating generally when coming off a highway on an exit ramp to a stop, while braking the car will begin to normally slow but then suddenly jump forward or feel like it is accelerating then continue braking. It feels like it is accelerating on its own. Every time I have had this into the dealer I have complained and they claim the issue cannot be duplicated. Finally, they have begun to tell me it is normal with this hybrid car. This is no normal event. This car is a menace.”
