Question: should I get the 21B10 PCM update? I've read many threads on the cam phaser issue but it's still not clear to me whether it is advisable to get that done. It seems that it's as likely to cause a problem as prevent one. I haven't detected any rattling, shuddering or knocking in my 2019 LTD with 16,200 miles on it. We got the Expy mainly for towing a 6,500 lb travel trailer.
I missed the February deadline required to extend the warranty for cam phaser issues, but that would have expired at the end of 2022 anyway, and the drive-train warranty is good until July 2024 and 60,000 miles. I assume any cam phaser problems would be covered until then.
Opinions?
