The Reduced Engine Power message alerts the driver that the Control Module has detected a fault in the Throttle Actuator Control system. The control module limits engine power when this mode is Active. Your computer will need to be scanned for codes and then diagnosed and fixed accordingly. My experience has been a bad throttle body or a bad sensor or some sort causing this issue.
