It sounds like they’re taking care of it, so that’s good. This one can be a tricky affair for some stealerships. My former local stealer didn’t have a moon roof tech and they were a pretty big service dept. So it was always a 2x scheduling problem, schedule with the stealership who then scheduled the remote repair. it took me 3 tries to get it repaired right. 1st time was 7 or 8 days and nothing - they pre-ordered my parts but then installed them in another truck. Rescheduled, another week and got it back fixed but rattling more than a bit.
S/A ordered tracks for it but they ended up just realigning and tightening everything and that seemed to help eliminate most of the rattling. I have a cab full of stuff so I’m pretty sure I have some other noise in the cabin as well as the moon roof, but the moon roof rattling is subtle now.
Just keep the seals lubed up and pop to vent before moving that glass rearward and you should be fine going forward.
