2002 Chevrolet Suburban steering problems

I was hit on the head inside my 2002 suburban, wearing my seat belt at 48 MPH by an oncoming mazda miata. My steering column collapsed, I went into oncoming 3 lanes of traffic, went up a curb, went through a brick retaining wall, and hit a telephone pole. My airbag did not deploy on any of the 3 impacts. Why? Also, my driver?s seat came off the track.

Tl*the contact owns a 2002 chevrolet suburban. The contact heard a knocking sound coming from the wheels when the front wheels were turned. She stated that the cause of failure may be the upper intermediate steering shaft. The dealer and manufacturer stated that she would have to pay $275 for the repair. The dealer did not have any recalls for the failure. The contact feels that there should be a recall due to the many repairs related to the wheel failure.
