Should be under warranty. Would press a dealer on it to get them to take care of it. Get names of who at the dealer/s you talk with and keep a record/file of what is or is not done. If they refuse to do warranty work contact chevy directly at 800-222-1020 or call gm headquarters at 313-556-5000 to file a formal complaint and attempt to resolve your problem.
