I see it's a few years after the initial posting but I am new here. Anyway, I had the same issue with my 04 GTP CompG at around
33,000 miles. It would come and go but most evident when making a left turn from a dead stop. Took it to the dealer, before warranty ran out. Dealer was able to duplicate the issue. There were, at that time, 3 service bulletins for the power steering pump dealing with pulley tension. They also had defective power steering pump housings - a crack in the casting. All was fixed and since not returned - now have 74,000 miles.
