2015–2016 Chevrolet Silverado 1500, 2015 Chevrolet Silverado 2500, 2015 Chevrolet Silverado 3500 and 3 other models Recall: Roof-rail air bag (RRAB) inflator end cap may detach from the inflator

The defect

General Motors LLC (GM) is recalling certain 2015-2016 GMC Sierra 1500 and Chevrolet Silverado 1500 and 2015 GMC Sierra 2500 and 3500, and Chevrolet Silverado 2500 and 3500 trucks. The roof-rail air bag (RRAB) inflator end cap may detach from the inflator.

The 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.

The fix — what to do

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. Owners may contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020. Note: GM filed a new recall, number 21V-504 that supersedes this recall. All vehicles previously recalled under 20V-736 will now be repaired under the new recall number 21V-504. GM's numbers for this recall are N202309680, N202309681, and N202309682.
