It's an easy fix.all you do is get some silicone grease(or silicone spray),open the sunroof on tilt,wipe on spray or grease with a rag on the areas(back half) of the rubber part of the glass sunroof that comes into contact with the metal part of the roof,you can also wipe some on the metal areas the rubber comes into contact with the metal part of the roof,close the roof and clean up any excess grease/spray.i did mine with the silicone grease and it's been good for approx.8 mths.
