Steering Wheel problems of the 2001 Mazda Tribute

Steering wheel will lock into one position during normal operation of vehicle. Wheel will turn to right, but cannot be turned any more to left. Steering wheel will lock up at low speeds. So far has not happened at high speeds. This event has happened three times, dealership witnessed this defect. Dealership was trying to determine cause of defect. A bolt was found inside the steering rack cover and was removed.

While driving at about 50 mph and coming to a fork in the road, as soon as consumer merged to right steering wheel got very stiff. Then, whole dash lit up. Consumer put on brakes/ put in park, and went to a Mazda dealer. Dealer could not find anything. At another day while driving at 60 mph consumer was bearing over, steering wheel got tight again, and vehicle cut off.
