Warning Light On problems of the 2012 GMC Terrain

On Feb 10, 2020 I was involved in a side impact crash when a large truck failed to stop at a red light. I took the vehicle in for repairs as the front quarter panel and wheel were damaged. The collision shop called today and stated that all four of my impact sensors are "dead". He said I was very lucky because there is no way I would've known that my airbags wouldn't have deployed and I very likely would've been seriously injured or killed. There was no warning light on the dash, and no code. They found it by accident on a more intensive diagnostic. This is scary because how many other 2012 Terrain owners won't know until one of their loved ones are injured or killed!?!? you need to do something about this. I got lucky but you have now 23 complaints about these bags not deploying. Please do something!!!.

The contact owns a 2012 GMC Terrain. The contact stated that while the vehicle was driving and on occasions while stopped, the service air bags message was displayed on the instrument panel intermittently. The contact stated that the passenger's side air bag was inoperable with the air bag warning light remaining illuminated. The vehicle was taken to two unknown dealers however, was not diagnosed nor repaired. The manufacturer had not been informed of failure. The failure mileage was approximately 126,000.
