I had my 2018 Expedition cam phasers and timing chains replaced under warranty, in 2020, at 50K. Purportedly, they are of new design intended to address the common start-up rattle. So far (~9k miles of operation), it has been running just fine with only a little, occasional, rattle at start-up. I just received my Dear Bill letter advising me of the latest Ford engineering department experiment.
Let me see if I have this correct. You want hundreds of thousands of already pissed off Ford customers to schedule appointments by 2/28/22, at understaffed and less than motivated service departments, to have a PCM flash that may take up to
"less than one and a half days, however, due to service scheduling requirements, your dealer may need your vehicle for a longer period of time". Additionally, if the experiment dosen't fix your rattle and/or shudder, you can then schedule a follow-up appointment with the now even more overrun and unmotivated service departments to change the settings back to the settings that also have the same base problem.
Anyone else reading this special "customer satisfaction program" offer differently? RU f$*^@!* kidding me?
I plan to discuss this with my dealer and see what they suggest but it is going to take one hell of a sound argument for me to become part of the latest experiment.
