Have been chasing leaks, and the DS one on mine was definitely leaking under the heavy rains lately. It was warped slightly and water was passing through to the headliner, down the A-pillar and into the wiring and carpet! I decided to pull the dust covers and add a thick bead of FIPG all around to seal them up...should keep the water out now...passed the hose test.
On a related note, does anyone know if the actual rubber seal around the sunroof glass is available? Mine is definitely not sealing, adding more water to the drain-system than I would like.

you can't get just the seal. You have to buy the entire glass with the seal, or shim the original with a section of bike inner tube. mine was hoes so I bought the glass from Cdan. It was around $350 shipped but I have no more leaks.
