It’s probably just fuel flowing over the top of the baffles. If a baffle was broken, and flopping around your tank, you’d know it. It’d also get worse the less fuel you had.
I found this on the internet do you think it's possible this could be the same problem with the 2020 Explorer?

If the straps are permitting too much movement of the tank, it can amplify the movement of the fuel which would create larger waves in the tank or would create waves in the fuel that collide excessively with each. Both would lead to sloshing around.

It could be that I just noticed it, but it started happening right after I over filled the gas tank. The auto stop feature on the gas filler was broken so I filled manually. I think I have may overfilled it.

For those who hear this noise, have you ever overfilled your gas tank?

Nice find Ricky. It could be the same issue.

I think this is a strong possibility. I’ll bring it up to my dealership. Thank you!

I found an easy way to hear the sloshing noise without driving the car. I just filled my gas tank, and if you rock the car back and forth from the left rear you can hear the liquid moving back and forth quite audibly. I've also been driving in the rain the last couple days, so haven't ruled out water being trapped somewhere.

I’ve been driving a lot with AC off recently and it’s quite pronounced. I notice it will slosh a couple times over a few seconds after an abrupt stop. It’s really pronounced with the engine start-stop function enabled.

My service advisor’s trying to pawn this off as normal, and that his “07 Mustang makes the same noise.” But if that’s the standard for a brand new vehicle I may need to find a different service center.
