Driving on state highway at posted speed. A deer ran into the right front and side of vehicle. Side airbags deployed. When the right side airbag deployed, it burned a hole in my passengers winter coat that completely went through the right sleeve forearm and scorched the sweatshirt that she was wearing under the coat. Smoke was visibly apparent in the cab of the vehicle. We thought the truck was on fire, then finally determined it was the sleeve of here coat.

Airbags failed to deploy after striking a street light pole head-on. The impact hit just right of dead center of the grille and shoved the front end back approximately 2 feet into the engine. There were no dash lights or warning lamps illuminated before the collision. I have notified GM and received a case number. I also have filed an insurance claim and the vehicle has been inspected by a reputable body shop and has been deemed a total loss. A police report was also filed. The vehicle is scheduled to be picked up by the insurance company on 5/18/21.
