Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My vehicle accelerates by itself while driving, when I change it from drive to reverse and when I press on my brakes at a stop light feels like is still accelerating and wants to go faster. I had two accidents because of this reason. Now my transmission is not changing gear anymore and this vehicle is at the mechanic for this reason. I'm having problems with the electrical system, fuel system but it was fixed by my mechanic. My main concern is the seat belts driver side and front passenger.”
