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, potentially causing serious injury or death.
This inflator recall applies only to vehicles originally sold or registered in high-humidity states and territories, including Florida, Texas, California, Hawaii, and several others. The overpressure risk is what makes this the most urgent issue on the truck. On the fuel side, trucks equipped with dual fuel tanks have a separate concern: a sticking low-fuel sensor in the front tank can cause the rear tank to pump too much fuel forward, overfilling the front tank until it swells and contacts the spinning driveshaft, which can punch a hole in the tank and spill fuel onto the road. There is also a recall covering certain fire extinguishers installed in the vehicle; the extinguisher may fail to discharge properly when needed, leaving the driver without a working tool if a fire breaks out.
