I will have to check my flex discs... Yesterday my wife was driving and we heard a loud pop and a burst of air hit her in the chest. We pulled over and looked, but found nothing. My wife asked me to drive as she was shaken up. When she tried to put her seatbelt on it was completely locked up. We decided to carry on to our destination and then take a closer look. Five minutes later as we were driving down the road the airbag went off without any reason whatsoever. It exploded in my face. We were able to park safely and noone was seriously injured. I do have a very bruised arm and the windshield is completely broken. The interior of the car had air blown all through it and did some damage (nothing that can't be fixed). It definitely felt like a freak accident. I am glad that this forum is here. At least now I can look at the car and figure out if that was the cause. Thanks for the info!
