These are closed evap systems, NEVER EVER EVER "TOP OFF" the tank or you will be buying a lot of very expensive evap equipment.
Just a little advise and my 2 cents.

Just a good mechanic or do some research. AMAZING how that "Do Research" comes up for about everything.

Thanks. Yes, that is correct. Actually i used Forscan and cleared up the code P0455 but it came up again. Reading around found some key points of failure (Hose, Gas Flap, Sensor).
I already made a appointment in the Dealer to see if it can be repaired by the Emission Warranty 5 years or at least get the estimate of what specifically is the problem. Let's see before i go further.

So, the diagnosis is an evap leak at the fuel filler neck. The part's on order and will arrive on Friday, so I'll be driving a loaner in the meantime.

Ummm, it's possible that you have the same issue but it's no where near a certainty.Hummmmm. Seems that i will have the same problem. If you can share the parts ordered when yo get it fixed please let me know. Thanks...

It's up to you to load the parts cannon if you want but, if it were me, I'd do some actual diagnostic testing. Find someone you know with a smoke machine, that's probably what Ford did to diag the OP's car.

EVAP is 100% emissions equipment and should absolutely be covered. You should have no issues getting it covered.Hummmmm. Seems that i will have the same problem. If you can share the parts ordered when yo get it fixed please let me know. Thanks...

But I wouldn't assume yours is the exact same part/problem. The system has many parts to it which can and do fail. And most of them will all throw the same code.

That was my concern when I heard that Ford was going to a "capless" fuel filler and apparently GM and others have done the same. Replacing a malfunctioning filler tube where the capless valve isn't sealing properly is much more of a headache than just buying a new gas cap like in the old days. Oh well, that's "progress".

Except we don't know that it's the flap that is leaking. Just somewhere in the fuel filler neck. It could be. Or it could be actual damage to the rubber hose/neck or something else.
I do agree if it had a gas cap that would be the first thing to check and I said so in my very first post. But other things on those systems failed too. I once had one where the metal lip of the filler neck corroded and even a new cap wouldn't seal. There are other things like hose clamps and barbs and connectors that can fail in both systems too.
Also, YouTube has several videos on the cleaning and care/maintenance of the filler flap so it's not always as dire as having to replace it.

All of this discussion makes me wonder why a leak developed in mine after just 2,300 miles. Just curiosity, since it's being fixed under warranty.

Without knowing what exactly is wrong it's all speculation.
Maybe something got pinched on assembly and wore a hole.
Or something wasn't on tight enough broke.
Or a defective part.
Or maybe a rodent chewed a hole. They've been known to destroy a lot of automotive parts.
A few years back, Honda I think, used something in the wiring insulation that mice/rats absolutely loved. Caused a lot of problems for vehicles that sat outside...

Rodent damage was actually my first thought. We've had that now with two of our vehicles, an Infiniti and a Mazda. We seem to have solved the problem by removing any place where mice or rats might nest close to our driveway, so we haven't had them nesting instead in our engine bays.
But, it sounds like this part is up where no rodents would go or be able to gain access to it.
