I was driving my 2007 Chevrolet Silverado on a highway at approximately 65 mph during a light rain shower when there was a loud bang sound similar to a shot gun blast and the seatbelt pre-tensioners pulled myself and my passenger hard back into the seats. The hazard lights began flashing immediately and the airbag sensor light came on. Contacted onstar to run a diagnostic and they showed there was a collision detected which fired the seat belt pre-tensioners. There was no collision, not even a bump in the road that caused this. This was a very startling event that easily could have caused a panic reaction and an accident. There was a smell of spent gunpowder in the cabin of the vehicle after this occurred. We unlatched our seat belts to relieve the pressure against our bodies and noticed they would not retract or pull back out. They are now useless. The injury was a bruise to my left collar bone where the seatbelt retracted. The vehicle is now not safe to drive since the seat belts don't work and for fear of the airbags deploying.

The contact owns a 2007 Chevrolet Silverado dur-max 2500. While driving approximately 55 mph at night, the contact slammed on the brakes to avoid a crash. He then crashed into a semi-trailer and struck a boulder. Neither of the vehicle's frontal air bags deployed. A police report was filed. The contact's vehicle was destroyed and towed to a local auto shop. He sustained injuries. The manufacturer sent an inspector to determine why the air bags did not deploy and he concluded that the contact was not wearing his seat belt at the time of the deployment. However, the contact stated that he was wearing his seat belt. The VIN was unknown. The current and failure mileages were 66,000.
