Hi everyone, just wanted to see if anyone has run into anything similar. Recently, at highway speeds, so like 60-90 mph, I've encountered a really loud buzzing/vibrating sound in the roof of the car seemingly on top of where the sunroof controls are. I've kinda narrowed it down since I can push the headliner up with some pressure and dull the vibrating.

I'm wondering if the heat of the desert southwest is finally catching up to me and the ~120 degree days are melting some adhesives or loosening some stuff up there behind the headliner, especially with the sun beating on it when it's parked in uncovered parking lots etc. Then the wind and road vibrations from highway speeds are causing something up there to vibrate loudly.

Really annoying and somewhat embarrassing when I have other people in the car as well since it's clearly audible above music from the radio.

I'm probably gonna bring it up at my next oil change but just wanted to reach out and see if anyone has any thoughts.

Thanks!

Are you hearing this with the shade closed or open, and windows up or down? I would imaging shade closed, windows up, AC on?

I'm hearing it with the shade fully closed and open. With it closed, the volume is muffled a little but same vibrating is heard.

I've felt the shade, the glass itself, and as much of the plastic and molding I can touch from inside the car and I don't feel a vibration corresponding to the noise so that leads me to think its something in the roof.

Do you have sunglasses stored there?...

haha nope I wish it was that easy

So update kinda is that I figured out that I could stop the vibrating noise (that sounded like it was coming from in front of the sunroof panel behind the switch to open and close it) by lightly pressing up on the back of the sunroof panel directly above my headrest. That confirmed my feat that it was something to do with the sunroof vibrating. The vibrating was getting louder than my music and it was driving me crazy on the highway haha.

So I placed some thin strips of felt tape on the top edge of the (wind deflector which the sunroof panel closes down on and compresses when you close the sunroof) and the noise is gone... for now. Hopefully that solved it.

I think the summer heat in PHX may have expanded some components of the sunroof fitment and caused air to be able to slip in and vibrate the wind deflector against the front of the sunroof panel or vice versa. And at highway speeds maybe the wind force was enough to make the vibrating noise audible? idk just a guess. Hope this fix holds up.

Thanks for the fix info. Excessive heat could be right. Are you out west?

Yup I'm out in Phoenix where its 115+ every day basically and parked out in open parking lots sometimes when eating at restaurants etc so I imagine temps in the roof probably reach like 150+ or something sometimes.

Funny thing is the vibrating started about the same time I put my rear roof spoiler on but unless the spoiler changed air flow on the roof dramatically enough to shake the front of the roof that much it's probably a coincidence and I really don't want to take it off to confirm.
