Known issues on the 2011 QX56. Three campaigns concern the 2011 QX56, and the first touches the fuel system: on certain vehicles the fuel pressure sensors were possibly tightened below specification and can back out under heat and vibration, leaking fuel and creating a fire risk. Certain vehicles have a driver air bag inflator that may malfunction or rupture on deployment. Certain vehicles equipped with 22-inch wheels carry a certification label with an incorrect axle weight rating, which can lead to overloading. Owners logged 79 complaints, led by the engine at 37 and the fuel and propulsion system at 18; 1 reported a fire. The manual gives fuel system torque values and specifications, plus engine diagnostics.
