Buying a 2020 Fusion/MKZ with 2.0 made in 2019 with 910 engine code

[northestPM]

I'm looking at a very low mile 2020 MKZ with the 2.0 Ecoboost built on 12/19. Ford's TSB for the coolant intrustion says it applies to engine code 910 and cars with a build date before May 2019. It's only got 25k miles on it. Only odd thing is that the top of the transmission fill hole is very wet.

I just want to make sure I'm not gonna buy this car with the coolant intrusion issue.

People say it's the 910 engine but this is 2020?

I disagree and wish automakers would stop marketing model years early. Yours was built in DEC 2019, so it has some parts and assemblies from the 2019 model year. Based on the link you provided this will be the faulty engine with coolant intrusion.

Fordtechmakuloco has info on this in one of his videos. It has to do with the cylinders protruding out of the casting, but do not tie into any adjacent block webbing. They have left the coolant space wide open for max heat transfer.

It is somewhat common to need headgaskets every 100 ~ 125K. The 2.0L as a whole ages much better than the other 4 cylinders.

December 2019 is after May 2019. This vehicle in question has the better revised engine which is supposed to not have the coolant intrusion. Plus it's a Fusion, which is most likely lighter than all or most of the other vehicles that this engine was put in.
