I`m beginning to think mine could be having some problems then. Maybe I will trade it at the store for a new one.

The symptoms: After I got finished with about 1/3 of the car I noticed a good bit of heat and turned it off to let it rest. When I picked it back up to finish the rest it was still warm and wouldn`t turn on but when I hit the switch off the motor rotated a little.

I have the 7346sp which is the exact same specs as the 7424xp except it comes with a sanding pad.
