Chevrolet Silverado 1500 Recall 20V736: Curtain airbag inflator end cap can detach and fly out

NHTSA campaign 20V736, reported November 25, 2020, 9,279 vehicles potentially affected.

What this recall means for you

The roof-rail curtain airbag inflator end cap on certain 2015-2016 Chevrolet Silverado and GMC Sierra pickups may separate from the inflator. When this happens, the compressed gas escapes and the end cap can be propelled into the vehicle, which raises the risk of injury or a crash.

General Motors will notify owners, and dealers will replace the roof-rail air bag modules on the left and/or right side free of charge. Interim owner notification letters were mailed on December 22, 2020. This recall has been superseded by GM recall 21V-504, and vehicles previously covered under 20V-736 will now be repaired under the new number.

Owners can contact GMC customer service at 1-888-988-7267 or Chevrolet customer service at 1-800-222-1020. Check your vehicle identification number (VIN) for open recalls to confirm whether your truck is affected.
