I just joined the forum to answer your question. I had the same problem you have. It took the dealer 30 days to figure it out (if you are a member of the "other forum", search out my detailed thread called "dealer problem").
It was finally fixed by replacing the drivers side steering knuckle. I would take it back to the dealer and get it done.
I got it too....backing outta the driveway wheel turned to the right...sounds like front left side. Shall talk to my dealership soon. Only happens when I am turning and hit a bump coming out of the driveway though.
