Incorrect. Only vehicles built before 8-April-2019. That is when the issue was corrected in production. Therefore it will only affect some 2019s, and not 2020's.

TSB is to standardize the labor procedures and parts only.
If they were replaced under the SSM then that is the updated part # and procedure.
"cwh" is incorrect...the solenoids and chain tensioners do not need to be replaced. The issue lies solely with the phasers and PCM calibration.
Understood. Unfortunately, dealerships (franchises) often misconstrue information provided to them.

Hey FordTechOne. First, thank you for the info and responses to this and other threads. Very helpful and appreciated!
I've been wondering why this only happens to some Raptors. Seemingly, most are not affected.
If this problem is caused by a design flaw, then it must affect all vehicles. If the design is sound, then the affected vehicles are likely having issues due to defective parts (and this assumes no one is beating on or otherwise treating their Raptor badly). Just speaking logically here.
From what you are telling, every 2nd gen Raptor, with a 2nd gen 3.5L ecoboost, before the April date you provided, has the original/faulty cam phaser design right? Theoretically, if the design has been accepted by Ford as faulty, and has been updated, then all vehicles with the old design should fail.
Have you gathered enough info that could explain why 75% of the peeps from this forum alone do not have this issue, and 25% do?
If the design is problematic, why do only some have this issue? It should affect all.
TIA

well said , sounds like its luck of the draw
The issue appears to be a manufacturing issue, not a design flaw. Engineering can design the most robust component in the world, but it is often up to outside suppliers to manufacture that component and provide it to the assembly plant. Unfortunately, issues sometimes only arise once vehicles are built and in the hands of the customer. That's when the investigation into the issue begins and a service message is published, which is what the dealer references to correct the concern.
The vehicles build prior to the cutoff date MAY experience the issue. My 2018 F-150 3.5 XLT had the noise before 10,000 miles; so from my experience if there is an issue with the phasers it will show itself early on. All phasers aren't defective, but if the issue is going to occur, it will be on vehicles before the specified build date. Reason is most likely that they cut off the supply of suspect parts on that date. However, that does not mean that all parts installed prior to that date are defective. Far from it, especially when they build almost 1 million trucks per year, and all models (Expedition, Navigator, F-150) have the potential to be affected

Oh. I read in another post of yours that Ford revised the part and updated the PCM calibration and April was the cutoff where vehicles will get the new part number(s).
If Ford revised the part, wouldn't that suggest that the part was a design flaw?

Not necessarily, and in this case most likely not. We are seeing the part failures early, and many repeat offenders. This indicates something else in the engine is causing the issue. While the phasers are the failure point, lack of oil flow to the phasers is the driving mechanism. Revisions of the phaser can make it more robust (ie operate with less oil, greater range of adjustment, etc), but if the problem exists elsewhere, it will fail again.
I've seen over 10 trucks with cam phaser replacements develop the problem again shortly after the fix. This indicates the problem is not with the component itself, but elsewhere. It makes complete sense to me that it would be a failing solenoid.
FWIW, I still calculated less than 1% of all Gen 2 Raptors have seen this problem. My dealer (which sells probably 20 Raptors a year) has only had a handful of regular F150s in for the fix, and no Raptors.
