2002 Oldsmobile Bravada engine problems

Going about 50 MPH on interstate when engine lost power. Had multiple warning lights and messages, including ABS and service brakes. Pulled off on exit ramp and stopped on grass completely off travel lane. Tried to restart engine several times with no success. Before I could take other action, I was hit in the left rear by another car, which pushed my vehicle about 50 feet back into the travel lane. Damage to rear quarter panel, bumper, and tailgate. My vehicle had to be towed to dealer.

While driving 55 MPH it was difficult to steer the vehicle. Service engine light illuminated, and the engine stalled. Dealer could not duplicate or determine the cause of the problem. 2002 oldsmobile bravada experienced problems with vehicle being difficult to steer.
