general problems of the 2001 Cadillac Catera

My husband was driving home from work when the accelerator "took over" and went all the way to the floor. He applied the brakes but they did not work. At some point the front wheel of the vehicle sheared off and flew off the car causing complete loss of control. My husband, a former navy seal, managed to "manhandle" the steering wheel enough to avoid a long line of oncoming traffic, but clipped the tail end of a trailer being pulled by a truck. He survived. We had only bought the car 5 months prior to this incident where it was totaled. It had been in the shop for 3 of the 5 months of ownership for computer problems. No one would take responsibility. Geico paid off the loan and we got nothing.
