The defect
The hub portion of the fan blade assembly could crack due to high stress levels generated during engine operating conditions. Eventually, the blade could break apart at the hub and blade pieces could be propelled into the engine. If the hood IS open while the engine IS running, the fragments would be free to fly from the vehicle.
The remedy
Dealer will replace the fan blade assembly without charge to owner.
