Example complaints

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

“While driving the car dragged, and when getting off the gas it slowed down really hard and started jerking y badly. Took it to a shop, and the computer read that air was getting in the gas, or something like that. They said it could be a number of things, but it was a manufacturing problem. Finally, I took the car to get fixed, and the mechanic won't fix it because there was nothing wrong with it. What do I do.”
