Did anybody ever resolve this issue?

I am experiencing the same thing, I think. I would describe the noise as similar to a small object inside a Pringles canister.

I already checked if I had anything loose (i.e. tools, spare tire, fender, etc. ), but to no avail.

Just like everybody else, I'm hoping somebody can lead us to a resolution.

Thanks.
JC
