It may be a default for one of many conditions. Usually it is relevant to a fault with the electronic throttle. Have you been able to have it scanned for fault codes?

You do have a message for engine overheat, the engine power reduced message is indicative to another fault.

That is one of the possibilities. What code(s) did you get?
