What's wrong, in plain English

Some GMC Terrain vehicles have an airbag control module that senses crashes and triggers the airbags. This module may not shut down correctly when the vehicle is turned off, which can leave it not working the next time the vehicle is started. When the module isn't working, it cannot sense a crash or signal the airbags to deploy, so the airbags may not go off when needed.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is included.
2. Contact a GMC dealer or GMC customer service at 1-800-462-8782 to schedule the repair.
3. The software update is free.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 18V340000.

Official notice

Component: AIR BAGS: AIR BAG/RESTRAINT CONTROL MODULE
Summary: 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.
Safety 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.
Remedy: 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 1-800-462-8782. GM's number for this recall is 18179.
