ON 12/14/07 WE WERE INVOLVED IN AN AUTO ACCIDENT. WE WERE TRAVELING AT ABOUT 50MPH AND RAN INTO THE BACK OF ANOTHER VEHICLE. THE WHOLE FRONT PASSENGER SIDE OF OUR YUKON IS TOTALED. THE FRONT END/BATTERY AND OTHER ITEMS IS PUSHED UP INTO THE ENGINE. MY CONCERN IS THAT NEITHER ONE OF THE AIRBAGS DEPLOYED IN THE ACCIDENT. WHY? THE IMPACT SHOULD HAVE RELEASED THE AIRBAG AND THE DRIVER OF THE VEHICLE HIT HIS SHOULDER ON THE STEERING WHEEL, WHICH THE AIRBAG WOULD HAVE PREVENTED THAT. *TR
