General Motors has recalled more than 9,700 Chevrolet Silverado HD and GMC Sierra HD vehicles, model years 2012 and 2013. In the affected vehicles, the transfer pump that moves fuel from the rear tank to the front tank could malfunction and cause the fuel gauge to indicate an inaccurate reading, according to the National Highway Traffic Safety Administration (NHTSA). As a result, the engine could stall, increasing the risk of a crash.
