Is it the sunroof itself making the noise or is it the headliner surrounding it? I have noticed a slight (but persistent) creaking on the drivers side of my sunroof but I am pretty sure it is the headliner making it. Almost as if some of the adhesive has let go and the headliner is chaffing against the roof??? I am going to attempt to fix it with a syringe full of Goop injected in the trouble spots.
