Collision Damage Repair
If your vehicle is involved in a collision and it is
damaged, have the damage repaired by a qualified

parts with which your vehicle was originally built.
Genuine GM Collision parts are your best choice to
ensure that your vehicle's designed appearance,
durability, and safety are preserved. The use of
Genuine GM parts can help maintain your GM New
Vehicle Warranty.
