Air Bag Not Deploy problems of the 2006 Nissan 350Z

My airbags did not deploy.

My wife was involved in an accident where she t-boned another driver after he made an illegal turn in front of her. The airbags in her car did not deploy. She hit this guy at approximately 35 miles per hour.

Driving home only 1/8 mile from my house, I collided head on with a small pick-up truck. My Nissan 350 car spun several times and came to rest. Most of the damage was to the driver side and front end. Front bumper completely gone. Driver side headlight completely gone, passenger side intact. Driver side door can only open a few inches, passenger side-fine. Driver side windshield cracked due to hood being pushed back into car, passenger side-fine. My concern and major complaint is that while my passenger side air bag deployed, the driver side nor the driver side air bags deployed. Had I been traveling at higher speeds or not wearing my seat belt and my air bag did not deploy, I could have seriously been hurt due to this, what I feel to be a, malfunction. To add, I had a 2004 Nissan 350z previously in which I had gently hit a curb, front, driver side and my side air bag deployed immediately. For the accident and the significant more damage that just occurred, there is no way that the air bags should not have deployed. I see similar complaints researching this and I am greatly concerned.
