The power steering quit on my wife about a month ago--when she let go of the wheel, it turned left to the stops. It was towed to the dealer, the gear was replaced, and the car sent home. On the way home, my wife was driving down the street, and the steering locked. She ran off the road, and trashed the front right side of the car (she's ok). The product liability dept at GM is working on the situation, I should hear something by Thursday. If you've had steering issues, be careful. At least this didn't happen at 70mph.
