While driving on highway at 50 mph, the power steering failed and the steering light came on. Luckily, i was able to slow the car down and get off of the highway. I pulled into a neighborhood and put the car in park. After several minutes, i put the car back in gear and the power steering was still out, but i was able to make it home. The next day, i started the car and the power steering was working. The steer wheel has jerked to the left/right on several occasions, but this was the first time that the power steering when completely out. I've brought the car to the dealer and am waiting for an explanation. *tr
