The 2003 Chevrolet Trailblazer I have owned since I purchased it brand new in 2003 was involved in an accident on 10/24/2010. My kids were driving when another vehicle sideswiped them, causing them to leave the road. When they reentered the road, the vehicle hit them again causing the Trailblazer to flip over a guardrail and rollover several times; landing on its roof. There were four vehicle occupants (including the driver). Neither driver, passenger side nor side airbags deployed during the accident.
My airbag has malfunctioned. The light remains on and I was forced to have it repaired even though many other models of my vehicles were under a recall on both frontal and driver's side airbags. My VIN# didn't apply but was showing all of the problems listed under the other models recall. It was about $450 to replace the malfunctioning coil which I had done at the chevy dealership.
My 2003 chevy Trailblazer was hit by another vehicle that ran a stop sign and struck the drivers side. This caused the front wheel and axel to break, caused the car to loose control, and flip end over end landing upside down. None of the front or side air bags worked.
While driving at 45 mph consumer was broadsided on the driver's side by a vehicle running a red light. Consumer was wearing a seat belt, but the side air bag did not deploy. Police arrived on the scene, but no one was cited. Consumer sustained non life threatening injuries.
