The steering wheel power adjustment function stopped working. The steering wheel went to the topmost position and got stuck there. It still telescopes in and out, but the up and down function stopped working, and it's stuck at the highest position and won't move down. The car has 52K miles and was not in an accident. Due to the strange position of the steering wheel, it is more difficult to control the car. There were no warning lights about this.
