GMC Terrain Vehicles Recalled Due to Malfunction with the Air Bag System
The sensing diagnostic module that senses a crash and deploys air bags may become inoperative
General Motors (GM) is recalling approximately 88,000 model year 2018 GMC Terrain vehicles.
What's the problem?
On the affected 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.
If the SDM becomes inoperative, it will not detect a crash or command the necessary air bag deployment, increasing the risk of injury to vehicle occupants in the event of a crash.
What happens next?
Owners of the recalled GMC Terrain vehicles will be notified by GM. Dealers will then reprogram the SDM with updated software, free of charge.
A specific owner notification schedule for this recall has not yet been announced. For more information, contact GMC customer service at (800) 462-8782—provide recall reference number 18179.
