2006 Saturn Ion POWER STEERING

Steering problem
2006 Saturn Ion 4 cyl Front Wheel Drive Automatic

My daughters power steering went out as she was driving and the light came on. After shutting the car off it quit. She called the Dealer and he asked if he had "jumped" anyones cars. She said yes her brothers. HE told he this would affect her car and take out her power steering and it would eventually go out. Costing her 800 to fix? I have never heard of anything like this. What is your take? Leigh
