Side/window Air Bag problems of the 1999 BMW 528

Consumer was approaching an intersection and another vehicle on other side of street ran stop sign. And collided with consumer's vehicle. Upon impact, driver's side airbag didn't deploy.

Drivers side and head protection system failed to deploy resulting in injury.

This BMW deployed the passenger side air bag, driving down the highway at 70mph. At the same time both front tires went flat. I do not know at this time if the tires were punctured by an object or not. My wife was driving the car and said that she was cruising at 70mph,(8:30am with good visability) when the airbag deployed she pulled over and noticed that she had two flat tires on the front. There was tire failure with this incident, however I only know that the brand tire is dunlop. The car is at the dealership at this time. This so far, is a real mystery to us!!!!!!!.
