Total loss of steering in my 2001 Tahoe. This was preceded by a clunking noise that could be heard under the hood and felt through the steering wheel. Fortunately, the loss of steering happened at a low speed and no accident resulted. In my owner's manual, it states that in the event of power assist loss on the steering, you can still drive the vehicle, it will just be more difficult to steer. This is not the case. The vehicle cannot be safely driven at any speed due to the amount of strength required to turn the wheel. This is a dangerous defect in the steering mechanism.
