So after reading many threads and searching the interweb i'm surprised i didnt come across this fix.

Slide open your shade and there is a plastic guard in between the shade and the glass.

Check to see if there is movement, i tapped it in the middle and sure enough the exact same noise. I can see by the passenger corner (there is a pivot joint) it felt loose and the movement was coming from there. Grabbed a napkin from the glove compartment and stuffed it in there to stop the movement and it worked!



I'm gonna cut some wooden shims and wedge it in where the napkin is rite now. That plastic piece doesn’t move and the wedge wont interfere with the operation of the roof.

 

Good stuff that's been driving me crazy.

 

thats pretty sweet. i never use the sunroof tho so i never hear the "rattle"

 

Ahhh thanks OP thought I was just going to have to deal with the rattle. Going outside to do this now!

 

so was that the culprit?

 

YESSS!!! thank you!

 

God I hope this is the answer. I'm going to try it this afternoon!

 

Is there a permanent solution for this fix?

 

Perfectly fixes the issue for me too. It's the drip rail. HOWEVER paper towels wedged in my sunroof is a less than IDEAL solution. Anything else come up? think replacing this part will solve the issue, perhaps the tabs that slide on the aluminium rail have worn down just a little causing the rattling?

I would use one of those stress relieving *****, more durable they paper, and they don't absorb water either

 

I was thinking of something similar, it needs to be able to easily side along the aluminum rail though. Like a little piece of fabric but with some thickness.

try using a piece of rubber silicone

 

Nice and easy fix
