This "flake" came from inside the top of the gas filler tube neck where the gas cap screws in...I've seen a couple of other small flakes at other times while I'm filling up...anyone else seeing this, should I be concerned about it eventually plugging up the fuel pump?...it's a 2021 with 5019 miles on it.

Is that like a paint flake? I went out and looked at mine. I had noticed that is was black (unlike other vehicles where it looks like bare metal). Didn't think too much of it, but when I tap it, it seems like it is metal. So is the inside of the filler powdercoated or painted, or maybe it is not metal but a hard plastic? Can you see any paint or coating missing with bare metal underneath?

I don't see any missing flakes. Maybe they have to protect the metal due to the hygroscopic nature of ethanol. Ethanol gas rusted the heck out of one of my generator gas tanks. I run non ethanol in anything that is going to sit for long and it does much better so far as rust is concerned. Will be interesting to hear other people's experience here.

To address your question, it would take a lot of those flakes to stop up the inlet sock on the intake fuel pump (assuming it is like most other in tank fuel pumps). I couldn't find a picture. Certainly not a good thing, but nothing to panic over. I would think that if it was going to cause a problem, it would probably do it within the powertrain warranty period and would be covered.
