2011 Ford Explorer air bags problems

I pulled into my driveway at a slow rate of speed, as I was braking the car was not stopping, as I pressed on the brake pedal it collapsed all the way to the floor but the brakes did not engage, just before the car hit the garage door which was directly in front of me the right front brake engaged, fully, stopping the right front tire only, the car pulled to the right and instead of hitting the garage door it struck a concrete column to the immediate right of the garage door.

I began experiencing problems with the steering wheel mounted controls while driving, which were intermittent. First, the volume button failed and then cruise control functions failed. The cruise control would sometimes cancel on its own, causing a sudden unexplained loss of speed while I thought it was engaged. The "resume" and "cancel" button functions also swapped. "resume" would cancel the cruise control and "cancel" would resume cruise.
