Popping Noise at Leading Edge of Pano Roof

[CGSTL]

Hey Folks,
Do any of you hear an occasional popping noise somewhere at the leading edge of the pano roof? Especially when the body is twisted - e.g. when going up a driveway bump at a 45 degree angle. The noise is not with the glass. It is somewhere in the metal structure between the top of the windshield and the open section. Just above the garage door opener buttons.

It does it when my roof is open and closed. Ever hear it?

I've never heard mine pop in that way. The only time I hear it pop is right after it rains and I push it to vent mode. Towards the very back, the rearward most edge POPS up quite loudly the first few times and then goes away.
