Air Bag Not Deploy problems of the 2015 Subaru Impreza Wrx

Avoiding a vehicle in blind spot. The vehicle in front of the truck in front of me hit his breaks causing the truck in front of me to hit his breaks, I clip the right front fascia into the left reat coner of the truck. The air bags did not deploy and the seat belt tensioner did not work. I pulled over, turned my vehicle off and my vehicle caught fire. My vehicle completely burned down to the frame and is a complete loss.
