I bought my Artisan 5-Quart Tilt-Head Stand Mixer on May 5 directly from KitchenAid and received it on May 9th.  I have used the dough hook several times for making bread, and, like many other reviewers, I find the ceramic coating peeling off of the hook.  This is obviously a known problem, with many reviewers reporting this already.  If I don't get a response to this review, I will contact KitchenAid next week.
