The defect
General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500, 2500, 3500, and Chevrolet Silverado 1500, 2500, and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator, or the inflator sidewall may rupture.
The risk
A separated inflator end cap or inflator rupture can allow compressed gas to escape, resulting in the end cap or other components being propelled into the vehicle, increasing the risk of injury or crash.
