While I was turning a 90 degree right hand turn onto a city street at approximately 20 mph, the steering column completely locked up while the car was in motion. Not power steering assist failure, but complete lock up. I slammed on the brakes and stopped the car. After turning the ignition off, then back on, the car could again be steered. This had never happened before, and we had bought the car new in 2000. Car now has 92,000 miles. The dealer removed the steering column lock at my insistence. No other part was repaired or replaced, according to the dealer. Old part is not available.
