As I was driving on a major highway, I hit a water puddle with the right front wheel during a rain storm as I was about to make a right-hand turn into a parking lot. As I began the turn the power steering stopped working. Had I not slowed down to make a turn, I would have hit a car in the parking lot, but I was able to avoid it, because I was going so slow at the time. I had all I could do, to turn the wheel and keep from hitting another vehicle. I called "onstar" and reported the problem. They asked if I wanted roadside assistance. I said I would wait awhile and see if it would work later. About an hour later it worked, but was whistling and groaning. I was able to make it home. The next day (Sunday) I took it to the dealer and they didn't see anything wrong. They advise me to call the next day for an appointment, which I did. It went in to the dealer at 10:30 am that day. Apparently there as a service bulletin about that problem and the fender liner/splash guard has been re-designed. A recall or letter notifying owners may prevent a serious accident.
