Im sorry to hear you have that problem.
I think that the pandemic-era QC, coupled with the newness of the platform, has you in a bad place.
It is possible that your unit is part of the shifting sands of model changes.
For example, mine is a late March build date, which means I should have a Bypass Valve on my hot charge pipes (Until 9/21 builds), but I do not.
There are ST's with "deletes", and others not, etc.
I would find out what part they're trying to replace, and grab the part number from the actual unit. Then, if it doesnt match Ford's expectation, you have the proof.
If Ford has the wrong info, they will always give the dealer the wrong part.
