Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I was driving on the interstate and the vehicle was in cruise control. It acted as it was accelerating and then the cruise control quit and I lost speed. I regained speed and then it lurched again; the cruise control again went off. When I applied the brake to pull to the side of the road, the engine started to throttle up and accelerate, I had to brake harder to come to a full stop.”
