2008 Lucerne: The stablitrack light and warning keeps coming on. It is proceeded with a clunk in the front drivers side wheel. There is also a scraping sound coming from the engine compartment along with a hesitation in speed. Have also noticed that when the brake is applied it will feel like there is something loose or rattling around between brake pads and disc. The car is unsafe!!!!!!!!!!! Dealer has made up some excuse about reprogramming the MODULE (?). Now the Module needs to be replaced. This a new car (2008) occurring within the first 20miles of use. Bought at Classic Cadillac/Buick in Montgomery Alabama. Should never have bought an American Car. Should have stayed with Toyota or Honda as in the past!!!!!!!!!!!!!!!!!!!!!!!!
