-?? The airbag system failed to deploy during a collision that resulted in the total loss of the vehicle. Additionally, the vehicle was operating with a 17-?? spare tire (undersized compared to the standard 20-?? wheels), which may have contributed to the accident. The vehicle has been totaled and is currently in the possession of the insurance company, but may be available for inspection upon request. -?? Despite the severity of the collision, none of the airbags deployed, which could have resulted in serious injury if the circumstances were different. The use of an undersized 17-?? spare tire may have affected the vehicle-??s stability, braking, or performance, contributing to the crash. -?? No. The vehicle was declared a total loss and has not been evaluated for defect reproduction by a dealer or service center. However, I am aware of related recalls and lawsuits regarding both improper spare tire sizing and airbag non-deployment in 2020-?"2021 GMC Sierra models. -?? The vehicle has been inspected by the insurance company during the total loss evaluation. A police report was also completed at the scene of the accident. To my knowledge, the manufacturer (GM) has not inspected the vehicle at this time. -?? No. There were no warning lights, messages, or symptoms prior to the crash. The vehicle gave no indication of any issue with the airbags or tire compatibility leading up to the accident. I was involved in an accident in my 2021 GMC Sierra. At the time, the vehicle was operating with a 17-?? spare tire installed, which I later discovered may be significantly undersized compared to the standard 20-?? wheels. During the crash, the impact was severe enough to total the vehicle, but none of the airbags deployed. Fortunately, there were no injuries, but I believe the non-deployment of the airbags represents a critical product safety defect. I-??ve since learned that GM has recalled similar vehicles for incorrect spare tires, and that lawsuits have been filed regarding calibration issues.

Airbag system did not deploy but smoke in cabin during a crash. Video of front, rear and inside cabin shows the rear end passenger side impact at an estimated 45-50 MPH. I saw smoke in cabin, disturbed with anxiety after crash waiting for bags to deploy accidentally. The airbag deployed red light illuminated notifying an airbag deployment. I received a GM message through the vehicle report application stating that my airbag system malfunctioned and I needed to take the vehicle to a service department for repair as soon as possible. This crash was a total loss of the GMC Sierra, this was how hard the vehicle was hit. Why did the airbag system smoke" Why did the airbags not deploy? Why did I receive a Malfunctioning Airbag system message from GMC" Video shows that if the airbag system would have deployed on the steering wheel I would have had less head and neck trauma when whipping backward and then forward.

Returned home after some shopping. Parked truck in drive way. Approximately 5 minutes after returning home my wife saw truck smoking from under the hood. Within another minute or two there were visible flames coming from the back edge of the hood. We called 911. Within 5 minutes the entire front end of the truck was engulfed in flames. The fire department arrived and put out the fire but the entire front and cab of the truck was destroyed. Fire investigators determined fire started at back of engine compartment near battery. Vehicle was stopped parked in off condition. In my driveway. No mechanical problems were noticed on ride home and there were no panel alerts for problems.
