Upon starting the car, the steering wheel jerks as well as the car as if it is going to take off. Also when driving the steering wheel will slightly jerk to one side or the other for no apparent reason. Spoke to GM and was given no help. These cars are having serious problems and I don't think GM gives a crap until someone gets hurt and lawsuit is filed. They know what is wrong with these cars and I just wish for once that us as consumers could get product we deserve. They are definitely getting an enlarged price for the vehicles.
