One evening driving home the power steering suddenly went out. It nearly caused an accident. We drove straight home and parked the car until Monday and had it towed to our dealer. Evidently once the car is shut off, the thing resets itself and starts working again, so there weren't any codes to work with. It was supposedly fixed by the dealer. Four days later, in a very sharp turn the power steering went out again. We ran off the road this time and barely got it under control. This time I drove to a gas station, filled up and the car ran all night until the dealership was open the next day. This time they got the proper codes and are fixing it right. I hope. I am trading it off asap.
