Summary
In some of the affected vehicles, an undesirable noise may develop from the cam phasers in the 3.5L GTDI engine. This noise might occur as a rattle when starting the engine after the vehicle was turned off for an extended period of time, or as a knocking noise when the engine is idling after it is warmed up. A cam phaser that has developed an undesirable noise does not affect the vehicle safety, performance, or emissions.
