This car has made a terrible grinding noise for over 2 years. The pads and rotors were replaced at 24000 miles within a few month's the abs and traction control failed completely. Work was done on the car replacing all of the electronic parts and sensors but the abs and traction are out again. Gm response is they will "fix" the problem even though they have yet to get it done after repeated attempts.
