On December 8, 2017, my 2006 Chevy Trailblazer spun out on snow while my daughter was driving. It went towards the left, then immediately jerked around to the right and continued to gain speed as it launched us off the roadway and into a group of trees. The brake pedal wouldn't budge, the steering wheel continued to turn in circles not controlling the tires at all. The backseat broke apart before impact and was throwing my teenage son around in the back. The front seats broke loose as well and slammed both driver and passenger into the dash during impact. The seatbelts did not engage to lock into place like they are supposed to and despite full frontal damage and a SUV deemed totaled/destroyed by my insurance company, not a single airbag deployed or attempted to deploy. We were all trapped inside the vehicle down an embankment and all sustained injuries in the crash including cuts, bruises, whiplash, and my daughter had a concussion. My daughter had a VP shunt placed in her brain last year and could've easily died in this crash due to her injuries. I spent all weekend and the next weekend researching online what could've gone wrong and found so many complaints from people who have experienced some of the same things happening to them and their loved ones. I have asked my insurance company to please investigate why the airbags and seatbelts didn't work, and the only thing the insurance investigator had to say was that it wasn't a front end crash. WHAT?? What part hit the trees then?? After looking up where all of the airbag sensors are on the 2006 Trailblazers, I find it amazing that not one of them triggered an airbag to deploy in my vehicle. Fifteen sensors were from the front seats to the front bumper and not a single airbag deployed! We rounded the curve at 25 mph but somehow accelerated to 57 mph when we hit the trees 50 feet from the road with no airbags deploying and no seatbelts locking us into place, and nothing concerns them?? Something needs to be done about these airbags and seatbelts not working!! Someone's going to eventually going to die in one of these vehicles!! How can I bring this to the attention to someone in charge of recalls to have something done before this happens to another family?
