2005 C6 throws up random warning, service soon, low fuel, anti-lock brakes abs lights, shocks inoperative, and more. Then you can shut it off and sometimes it will go away. And sometimes it will come back.
Heard a sound comming for the rear of the car, thought I had a flat tire car pulling to one side. No flat tire. When I started to go rear end made a sound. Going to take it in to be checked out. When you go yo take off there is a delay and a sound comming from the rear end.
