NHTSA recall 18V340000
Air Bags · General Motors, LLC
Details
What's wrong: 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.
Why it matters: 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.
