just a question about my steering, i reversed out of my drive the other night and i tapped the curb on full lock and the steering wheel went stiff and the red wheel light came on, i checked around the car and it seemed ok, but the steering wheel wouldnt move and it wouldnt turn off city mode, so i turned it off and started it again and everything was ok again with the red light going off, only problem since is the wheel was a slight creaking for about 10 minutes yesterday, anyone know what happened?
