The 2014 GMC Sierra 3500 has 3 recalls, the most serious being a Takata-style passenger airbag inflator that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death.
This recall only affects vehicles originally sold or registered in certain high-humidity states and territories. On the fuel side, trucks equipped with dual fuel tanks have a low fuel level sensor in the front tank that can stick, causing the rear tank to pump fuel into the front tank until it overfills. The excess pressure can cause the front tank to expand and contact the driveshaft, potentially punching a hole in the tank and creating a fuel leak. There is also a recall covering certain fire extinguishers included with the vehicle that may fail to discharge properly when needed.
