Side/window Air Bag problems of the 2007 BMW X3

I was travelling down a 3 lane highway behind a cube van going slowly. As I moved in to the next lane to go around him, I saw there was a pre-existing multi-car accident that had just occurred in that lane right in front of me. I immediately slammed on my brakes to avoid adding to the mess. I was able to stop in time. I had zero contact with any vehicle or object. As I slammed on my brakes, my front drivers side airbag and 2 of my side airbags inadvertently deployed. The front drivers airbag cracked the top of the windshield. Pictures were taken of all the vehicles involved at the scene, including mine. My car would not start, so it had to be pushed off the roadway and towed to my home. The next day, my insurance company allstate sent an airbag expert to my home to investigate the situation (tiffany duncan 301-974-9653) and to make a determination as to whether there had been a collision. She took her own pictures, which have been obtained and will be provided to NHTSA. She confirmed and reported that no contact had been made by my vehicle with any other object or vehicle. There was no damage. There was no collision. Although I have full coverage, allstate has not opened a collision claim on this vehicle. I have no car, no rental car because there was no collision. The car was towed to BMW of annapolis 410-349-9312. The analysis is being handled by a tech named allen. He was unable to make an accurate assessment yesterday, so bwm corporate hq in NJ has taken over, betsy holman 201-571-5859. They determine if there is a manufacturers defect, I will not be able to get a car. Now, my mom is struggling to get to work (at NHTSA) and I have to take her car to get to my brand new job of two days. I have a defective airbag situation. I hope NHTSA can help me prove that I have a defect. Thanks hugh skinner.
