Wheels slipping when hard lock turning - dealer says this is normal?

[CoryM]

If the front toe is incorrect you can get these sort of issues. You will notice a dragging, or shudder while turning tightly at LOW speeds. As in, pulling into a parking spot speeds at full lock. If you are going too fast for the corner almost any car will do this to some degree. I would suggest having your alignment checked, although it definitely should have been done after the work you had done.
Cheers.
