You must visit a General Motors dealership to perform recall repairs on your GMC truck or Chevrolet truck. The schedule for General Motors to initially contact known owners of affected vehicles was during May, 2014. If you did not receive a notification, but wish to check to see if your vehicle is included, please contact one of your local General Motors dealerships. They will also check for any other incomplete recalls on your vehicle. For best results, be prepared to provide your Vehicle Identification Number (VIN) to the service department consultant you speak with. The General Motors recall designation is 13420 and 13421.
