Hey team, sending an update and hoping maybe this helps someone else.
After 13 months of trying to resolve this issue, I'm hopeful and optimistic that I have done just that.
This has worked for me and I have been rattle free for about a month now, so ideally this was both the issue and resolution to my problem.
I always had what sounded like glass on metal, a rattle that didn't sound like a loose screw (I checked em all up top, all super tight) but more of glass tapping on something, a piece of metal.
Some days were worse than others, and when the roof was opened even a tiny bit or tilted in the back the noise was gone.
If the roof was closed and the shade drawn I could sometimes hear the rattle even over low radio volume and it drove me nuts.
I purchased the felt pads, sticky on one side, and placed them in different places throughout the sunroof area in spots I thought could be the culprit, both inside the car, on the glass, and in areas of the actual sunroof mechanisms, anywhere that didn't interfere with sliding or moving parts.
Finally, I randomly see this small rail that the glass sits on both on the left and right side and towards the front and only visible when the roof is opened and only because I looked for it.
What I ended up doing was putting one of the felt pads on this rail in the front, and on the back area of the rail, the pad went in easy, and on the front of that rail (closer to the front of the sunroof, basically windshield area) I almost couldn't even get the pad on top of the rail, under the glass.
I had to push up super hard, which corresponded with what I also would do to make the rattle noise go away and kind of how I isolated the area, and got most of the felt pad in there.
Anywho, the pic is zoomed and is the foam above the metal rail in between it and the glass. I have other pics but they are too big to add to this thread evidently.
I did this on both sides and all of my noise issues are gone completely and have not returned. Also, since this is on the inside, there is no concern of water fastness which I have also tested.
So long story short, this so far has resolved a long running issue and the real only thing that I disliked about this car (other than the back windows not rolling down all the way) and I'm stoked it worked for me, but I know other folks may have different causes of their noise issues. It isn't a super clean install by any stretch but you don't see it when it's closed anyways so I'm good with it haha.
Hoping it may work for others out there as well, and should the rattle return any time soon, I'll update yall, but getting close to about a month of no noise now!
