Air Bag Not Deploy problems of the 1997 Nissan Maxima

With extensive front-end damage the air bags did not deploy. While driving our vehicle on the interstate, my son rear-ended a Ford winstar van. He believes that he was going approximately 60 mph and was able to brake to some extent before hitting her rear bumper. Fortunately no one was injured. However there was extensive damage to the front of the Maxima. This included the front bumper, grill, radiator, hood and other components that I was unable to assess. However our body shop and insurance company felt that the cost of repairs exceeded the value of the vehichle such that they "totaled" the car. My concern was that with such extensive front-end damage the air bags did not deploy. Nissan seems to think that this was appropriate. How can we determine if this is correct. Please advise. Thank you. Follow up letter from 10078979.

The vehicle was hit at 25 mph in the front center but the air bags did not deploy which caused minor injuries to the consumer.

Vehicle stopped in traffic. I was hit in the rear by a 2000 Ford f150 truck. I was propelled forward, then back into the seat, the seat back collapsed. I sustained neck, shoulder, back, hip and knee injuries. My car was pushed into another car in front of me. The airbags in my car did not deploy!.

Air bag warning light is illuminated on the dash, in the event of a collision air bags will not deploy. Consumer has contacted dealer. Dealer noted that air bag modula needed replacement. Please provide any further details.
