The problem
General Motors, LLC. (GM) is recalling certain 2022 GMC Acadia vehicles. The sensing diagnostic module (SDM) may have been left in "manufacturing mode" and not activated at the assembly plant prior to shipment. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."
The risk
The air bags will not deploy with an unactivated SDM, increasing the risk of injury in a crash.
The fix
The vehicles will be returned to the assembly plant for SDM activation. Both affected vehicles are still in dealer inventory and therefore no owner notification letters will be mailed. Owners may contact GMC 1-800-462-8782. GM's number for this recall is N212344261.
