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!!!

While driving, there is a random ding. No idiot lights come on this has been going on for over a month. Today I happened to look up and the passenger airbag light was flashing. As if stating there was someone in the seat. The only way to stop it is to have the passenger seat belt buckled while driving. This only happens while driving. It is very disturbing because I am not sure if I am in an accident if my passenger will be safe.

My service bag light came on about 1 month ago. When I took it to the dealer to check it out. They said my year is not in the recall list. They also said none of the air bags will work until it gets fixed. I am living on a limited income and cannot afford to fix the air bags. Every year before and after of gmc terrain have been recalled. I don't understand why my 2012 has not been recalled. With this being a manufactured problem I believe gmc should pay to fix the air bags. I am afraid to take my grandchildren with me to the store.
