Air Bag Not Deploy problems of the 2011 Buick Enclave

Driving down the road on a 50mph zone and a vehicle pulled out in front of us. Our car t-boned the car that pulled in front of us. Everyone had there seatbelts on but the front airbags never deployed. I dont understand why they wouldnt have deployed when we hit the other car at at least 40mph after slamming on the breaks.

Auto transmission and torque converter would not hold vehicle.

Driver exiting a parking lot did not see my vehicle and did not stop. Hit my vehicle mid way on the passenger side pushing my vehicle sideways causing it to hit a light pole on the driver side front fender and hood. Air bags did not deploy and seat belt did not work causing me to hit the steering wheel with my chest and my knee on the dash. I was taken to emergency room. Nothing was broken but had extensive soft tissue, muscle strains and cartilage damage. Am still receiving treatment at this time.
