Query: Mixer smoked like crazy on 3rd use.

The manual that came with my new mixer said that an electrical-burning smell was normal, as was the housing getting so hot that I could not touch it. So, when my first two uses of my mixer did both these things, I was unhappy, but not worried. Then on the third use, smoke began to pour from the back and I had to carry it outside (remember the hot housing!). This was not covered in the manual, nor was their customer service open on the weekend (people only cook on week days?). Checking consumer review sites, this problem is sufficiently frequent that I won't be getting another KitchenAid.
