Component
AIR BAGS:SRS MALFUNCTION WARNING LAMP/LIGHT
Manufacturer
General Motors, LLC
What Happened
The sensing diagnostic module in your vehicle helps the airbags deploy properly. It talks to the communications gateway module, which has a bug that can cause the 'air bag malfunction' light to flicker or not turn on when it should.
Risk if Unfixed
If the light doesn't come on when there's a problem with the airbags, you might not know there's a danger inside your vehicle. This could put you at risk of injury in a crash.
Free Fix
Your authorized dealer will update the software in the communications gateway module for free. This will ensure the air bag malfunction light works correctly. You'll get a notification with instructions on when to schedule the update.
