Acadia

  • 10,000 miles
In light of the all the safety recalls by GM for ignition switch failures, I believe that my wife's crash in our 2008 GMC Acadia was the direct cause of the ignition switch failing. Driving North bound on AZ route 89 in the area of prescott, AZ called the granite dells, the car proceeded straight where the road turns slightly to the right. The cat proceeded into and partially up a granite stone out cropping on the opposite side of the road. The car then went air borne landing up side down on its roof in the middle of route 89. I believe that this accident happened due to ignition switch failure which in turn shut off the engine, power steering, and the entire air bag system which in this accident fail to deploy. My wife was air lifted to northern Arizona medical center in flagstaff, AZ for sever head injure from which she has recovered. It is my belief that the ignition failures that have shown up on other GM cars is also a problem for the 2008 GMC Acadia and possibly other like models of GM vehicles. In my opinion it has to be ignition switch failure that shut down the engine, power steering and air bag system causing this accident.
