2012 GMC SIERRATransport Canada Recall #2013438
The official notice
Defect
On certain pickup trucks equipped with a 6.6L diesel engine and dual fuel tanks, the fuel tank transfer pump may malfunction, stopping the transfer of fuel from the rear tank to the front tank. This could cause the fuel gauge to display an inaccurate reading, and cause the front tank to become empty while fuel remains in the rear tank. This could result in engine stalling which, in conjunction with traffic, road conditions, and driver's reactions, could increase the risk of a crash causing injury and/or property damage.
Safety Risk
No risk description available.
Remedy
Dealers will replace the fuel transfer pump.
