Verbatim excerpts from NHTSA complaints, by component
Air bags
1 report1 crash
“My husband and I were traveling on the highway doing 75mph. A deer ran out in front of us causing a crash. The front end of the car was extremely damaged and onstar reflects the drivers side air bag deployed (which it sounded like when we hit as we heard a big bang) but no air bag deployed. The car also immediately locked up. The driver stated he could not brake or accelerate and lost all steering. The brake locked up and we went from 75-0 immediately. Thankfully there was not ice on the road as we would have been just full force ahead and thankfully there was no one behind us as they would have totally been in our back seat. Both would have been even worse of an accident then they already were! There was smoke from the brakes (obviously going from 75-0 caused some brake wear and tear) EMT looked at the seat belts as the passengers retracted after she slid forward causing injury to the abdomen. The driver was able to brace a little so not as bad. Insurance is inspecting it today for damage so totality of the damage is unknown at this time. Prior to the Collison the lights warning you of a collision went off but there was no time to react.”
