My car has had similiar binding problems...around tight turns, and especially from stop to speed in the tight turns. I redid all fluids, as I do every 15,000 and took it back today and they added a full bottle of LSD additive. Despite the diif fluid being synthetic, it is said it does not require the LSD. Well as it seems they do. With the addition of more LSD the problem is gone. I will go back tomorrow and have them add another bottle for piece of mind and problem resolution. Hope it is the same for you
