- Summary
- 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."
- Consequence
- The air bags will not deploy with an unactivated SDM, increasing the risk of injury in a crash.
- Remedy
- 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.
- Notes
- Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.nhtsa.gov.

Has your GMC been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A GMC dealer can also check your VIN. Recall repairs are free.
