My car said to me this not that there is something wrong with the Service Safety Restraint system! It was fine last night when I got home! I just bought this car a month ago and everything was fine and now my air bag light is on and will not go off!

The "Service Safety Restraint System" warning light appears on the dashboard and warning chimes continually sound. To my knowledge GMC had a recall for this in 2018. I purchased the vehicle in 2021. I contacted GMC and told them this issue and they informed me that there are no recalls on the vehicle. My concerns being that airbags are fully functional.

The Safety Restraint System warning keeps coming on and off as well as the air bag light. It happened months ago so I took it in and got it looked at and scanned. All the seatbelts were checked and the scan came back with nothing. Then it stopped for a couple months and now it has started again. Ive had 14 surgeries in the last little less than 4 years and I'm about to go into my 3rd back surgery since November. I cannot get into an accident and not have airbags as I've also had brain surgery 3 winters ago as well. I am disabled and do not have a ton of money either for fixes that aren't necessary but this safety issue is crucial to me. I see that many 2018s have been recalled for the exact same issue that I'm having however mine doesn't come up with that but it is happening to me so that should be included. I also need some direction if not as to why this is happening because I cannot afford to have a dealership, no less, replace every tiny little thing looking for the culprit at $150 an hour when I live on $1,200 a month and most goes to medical. Please advise on what to to or where to start. Thank you.

Started car in parking lot. Warning came on saying “service safety restraint system” and airbag illumination was on. Just notified salesman as I have only had this vehicle about 10 days. Bought it used. Unfortunately.

I was sitting at a red light in the left hand turn lane. A truck ran their red light hitting another truck sending both of them crashing into my vehicle. The first truck struck the front bumper at the headlight & skid all the way down the side of the vehicle then the other truck was slammed into the side of my vehicle. All the damage was on the driver side of the car. My car was moved over into the next lane but no air bags went off. This happened on a hwy where the speed limit is 65. The truck running the red light was going at least that fast and never hit their brakes.
