What is wrong

General Motors LLC (GM) is recalling certain 2018 GMC Terrain vehicles. The sensing diagnostic module (SDM) that senses a crash and deploys the necessary air bags may not power down correctly when the vehicle is shut off, causing it to be inoperative when the vehicle is restarted.

The risk

If the SDM becomes inoperative, it will not detect a crash or command the necessary air bag deployment, increasing the risk of injury in the event of a crash.

The fix

GM will notify owners, and dealers will reprogram the SDM with updated software, free of charge. The recall began June 29, 2018. Owners may contact GMC customer service at 1-[removed]. GM's number for this recall is 18179.

Notes from the manufacturer

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-[removed] (TTY 1-[removed]), or go to [link removed]
