I haven't heard this personally. However some friends who took my beast for a joyride said they heard something concerning from the back and based on their description this sounds like it might be similar or the same thing.
There are 2 drainage holes with flaps above the tailgate on either side. I've heard that these sometimes cause noise. A few folks on the regular F15/F16 side of the house said they had the dealer address it.
I will bring it up when I bring it in for a few of my other concerns.
