I was traveling about 75mph when a deer ran infront of me, I wasn't able to stop completely and hit the deer on my right front side of my vehicle.. the smell of smoke came from my vehicle and my "service airbags" indicator came on.. no airbags deployed.. I had my 6 year old son in the car with me!! my car isn't drivable due to the signal being on even though the airbags didn't deploy.

Sudden unintended acceleration when vehicle shifted from park to drive, resulted in extreme high speed acceleration and no control of vehicle. This resulted in a high impact crash into garage side wall. Also air bag did not deploy. Assume throttle wide open causing sudden acceleration. Insurance report, and police report pending

We had begun to cross an intersection and, while our speed was from a dead stop, the other driver blew through a red light and hit us at what was probably the speed limit of 40mph. Her car struck us in the right front passenger side and again on the rear passenger side. We, myself who was driving, and my wife, who was the passenger on the side hit, were both thrown hard to the right at impact, causing injuries to us both, most notably, my wife. She hit her head very hard on either the passenger door frame or the passenger window. No airbags deployed. No side airbags, no front airbags. No air bags deployed!

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.

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.

The contact owns a 2012 GMC Terrain. The contact stated that while sitting at a traffic stop, a semi-truck crashed into the rear bumper of the contact's vehicle. The contact's vehicle was pushed forward, causing the contact to crash into a preceding vehicle. The air bags failed to deploy. The contact sustained injuries to the hand, neck and back. A police report was filed. The vehicle was towed to an independent mechanic for diagnosis but they were unable to duplicate the air bag deployment failure. The manufacturer was notified of the failure. The VIN was not available. The approximate failure mileage was 32,000.
