2013 GMC Sierra 2500 HD RecallsThe Fuel Gauge Reading May Be Incorrect
Vehicles equipped with a 6.6L diesel engine and dual fuel tanks are being recalled because the transfer pump that moves fuel from the rear tank to the front tank could cause the fuel gauge in show the incorrect fuel level. The engine could stall unexpectedly, increasing the risk of a crash. Dealers will inspect the fuel transfer pump and replace it as necessary to correct this concern.
The label that indicates "CNG Fuel Only" is too small. Owners of affected vehicles will receive replacement labels from General Motors, and dealers can help with installation, free of charge to resolve the concern.
All late model vehicles are equipped with a "Shift interlock" system that prevents vehicles with and automatic transmission from being shifted out of the Park position under certain conditions. Some of these vehicles are being recalled because they may have been assembled with a broken park lock cable or a malformed steering column lock actuator gear. Failure of these components can allow the shifter to be moved out of the Park position with the ignition key removed or in the off position. This can cause the vehicle to roll away unexpectedly increasing the risk of injury or a crash. Dealers will inspect the recalled vehicles and replace the steering column as necessary.
