At startup when I put the vehicle into forward or reverse gears the engine races and the vehicle lurches in reverse or forward depending which gear it is in. Since I have my foot on the break while putting it into gear I haven't had an accident. Also, several times when this happened the service engine light came on and the vehicle had very little power. After I turned the engine off , sat awhile and turned the engine on the service light did no come on until this happened again. I have heard of this happening to others ,so, consequently, I believe this could be a manufacturing defect.

Also car revved while driving and could not go over 40mph without the engine revving to over 5,000 rpm. This is not safe and has been reported numerous times.
