Air Bags:side/Window:curtain:inflator 2021-07-01 · campaign 21V504000 · 410,019 vehicles
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.
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.
Fix: Dealers will replace the left and right side RRAB modules, free of charge. Interim owner notification letters informing owners of the safety risk were mailed on August 18, 2021. Owners will receive a second notice when the remedy is available. Phase I owner notification letters were mailed on May 5, 2022.

Risk: If the end cap separates from the inflator, the compressed gas will escape and the end cap can be propelled into the vehicle, increasing the risk of injury or a crash.
Fix: GM will notify owners, and dealers will replace the RRAB modules on the left and/or right side, free of charge. Interim owner notification letters were mailed on December 22, 2020.

Risk: If the brake pedal becomes loose or inoperative, the driver may be unable to stop the vehicle by using the brake pedal. Additionally, a loose pedal may also interfere with the accelerator pedal. Either condition may increase the risk of a crash.

Fuel System, Gasoline:storage:auxillary Tank 2017-10-19 · campaign 17V664000 · 35,292 vehicles
Defect: General Motors LLC (GM) is recalling certain 2011-2015 Chevrolet Silverado 3500 and GMC Sierra 3500 trucks equipped with dual fuel tanks. The low fuel level sensor for the front tank may stick causing the rear tank to overfill the front tank.
Risk: If the front tank overfills, the excess pressure may cause the front tank to expand and contact the driveshaft, possibly resulting in a hole in the tank. The hole will leak fuel, which in the presence of an ignition source, can increase the risk of a fire.
Fix: GM has notified owners, and dealers will replace the rear tank fuel pump or update the fuel-level sensor software, as well as inspect the front tank, replacing it as necessary, free of charge.
