Air Bag On-off Switch problems of the 2007 Honda Civic Hybrid

Hi we bought this car 3 years ago and we took it for inspection maybe 10 months ago. We were told my the Honda dealer inspectors that the car didn't need to fix any thing, and that if the car need it any repairs the car did not qualify for it. Since the car had more than 100,000 miles. But on December 16,2016 my son was driving under the rain and as he was switching lanes to exist the freeway his car lost control hit a ramp in the freeway got a damage on the rear bumper, but the most scary part is that the air bags did not not deployed at the time of the impact. Instead only the driver size came out did nothing to support his head because the bags did not deflate at the time of the impact. The other defect was that his seat which was the driver sit was ripped from the side and again the air bad did't deflated . The damage on our vehicle was so severe from the inside that the insurance has declared this car as a total lost .
