Model Years Affected: 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2008, 2010

Engines Affected: 3.0L V6, 3.0L V6 DOHC

Average Mileage: 107,988 mi (11,200 mi - 289,800 mi)


The engine may misfire and/or buck while driving at freeway speeds with no fault code stored in the powertrain control module (PCM). This can be caused by an intermittent fault with the camshaft synchronizer assembly. This condition can be diagnosed by monitoring knock sensor data as per Ford service bulletin #05-22-12. Replacement of the synchronizer assembly will be required to correct this concern.

    the car will run smoothly then without notice it will chug a few times. This genrally happens at 55 to 70 MPH and when on an incline. It will sometimes happen at lower speeds but doea not seem to do it below 40 MPH.

    Engine misfires, bucks and jerks at highway speeds, particularly toward the end of long trips (2- 4 hour trips). Had camshaft replaced and it went away for about 3 months then returned!
