2017 Nissan Titan SV 4x4

Hi all! I wanted to see if anyone else has this happen:

When I fill my gas tank and it starts to get close to full there is a whistling sound that grows louder and louder the more full it gets.

Does this happen to anyone else?

Is this a manufacturing design to let you know?

It’s kind of annoying to me.

Any insight would be great.
