Open the full vehicle complaint log (all categories)My vehicle is rear-ended by a large earth mover branded as a Kenworth. My vehicle was then pushed into another. After the initial impact, my engine went racing above 5,000 RPM. It was disengaged from the transmission. I switched my car into neutral, shut my car off and the engine was no longer racing when I restarted the car. Because of an engine racing, I am concerned about the potential that somebody's transmission would be engaged and it could cause serious further injury.
