8 Air Bag Not Deploy problem

Failure Date: 03/13/2014

I inadvertently veered off side roadway, (va highway 220) colliding with a tree/roadside shrubs, etc (was knocked unconscious as forehead hit steering wheel on initial impact). Airbags did not deploy allowing me to sustain a head injury that knocked me unconscious. . . Forehead was gashed with significant bleeding. I was transported by ambulance in unconscious state. Damage to vehicle is in excess of $8,000 so far as vehicle still in repair shop with massive front end damage that affects steering linkage, etc. The impact of vehicle against foliage, trees shrubs, should have forced air bags to deploy and I believe that I would not have sustained a head injury that rendered me unconscious with mild concussion and could not control vehicle leaving roadway.

Veered off side of highway, struck something head-on and was rendered unconscious as head hit steering wheel. I was transported unconscious in ambulance from crash scene to local hospital, where I was an inpatient for two days. Extensive damage to front of vehicle indicated the severity of impact. . . Yet air bags did not deploy. I believe air bags should have deployed on impact and I would not have been rendered unconscious, and could have controlled vehicle to avoid striking tree, brush, etc. I contacted GMC corporate. . To advise my concerns for safety. . . Received a follow up telephone call from GMC representative. . . (he) expressed no interest in my complaint. . . Refused to comment on my statement that air bag failed to deploy resulting in extensive damage to front of vehicle and sustaining a head injury as no bag deployed. No matter that I am leasing the vehicle and fear for my safety. . . I was advised that GMC had no further interest in this matter and would not evaluate my safety concerns.
