Fan (engine and engine cooling)
The flex blade fans on the involved vehicles may develop cracks in the laminated stiffener as a result of fatigue during operation. If such a condition exists and the cracks go undetected, continued operation could cause pieces of the stiffener to break off.
Remedy: Dealer will replace the original fan with a steel fixed blade fan, free of charge.
