The problem
SOME OF THE FLEXIBLE FIVE-BLADE ENGINE COOLING FANS MAY BE SUBJECT TO HIGH BLADE STRESSES THAT CAN RESULT FROM RESONANT VIBRATION INPUTS OCCURRING DURING NORMAL VEHICLE OPERATION. THIS CAN LEAD TO FATIGUE CRACKING OF THE BLADES. PORTIONS OF THE BLADE MAY SEPARATE FROM THE FAN ASSEMBLY WITHOUT PRIOR WARNING.
What owners should do
DEALER WILL REPLACE FAN WITH AN IMPROVED FIVE-BLADED VERSION WITHOUT CHARGE TO OWNER.
