Bought a KitchenAid stand mixer - the motor made a loud "aircraft landing" sound. When I called the number in the instructions they told me that their warranty doesn't cover sounds, and that they couldn't do anything for me. I tried to explain that I had worked with motors a lot, and this wasn't a normal sound, and asked to speak with a supervisor. The supervisor told me the same thing - no warranty for that type of problem. I haven't bought anything from KitchenAid since then.
