2014 BMW 328I air bags problems

I have had 4 car crashed quit this vehicle and neither time have the airbags deploy and I have became injured from the car crashes in my airbags never deployed, I can't hit a car from the front I have been hit from the back and neither airbags have deployed even a passenger got in on the site and that are back did not deploy either. My vehicle is in motion every time that I crashed or was crashed,

2007 toyota highlander observed running red light and t-boned the driver's side of a 2014 BMW 328ix. Impact of collision was meaningful and direct, generating in excess of $10,000 of structural repairs to driver's side alone. No air bag deployment (front, side, curtain, etc) in the BMW despite of magnitude, force and placement of the collision. Driver of BMW sustained severe head, facial and bodily injuries requiring invasive medical attention and protracted physical therapy.......updated 12/15/15 updated 9/7/2017
