Default Sunroof rattles

I have a 2023 is500 and my sunroof has been rattling. I think it has to do with the sunroof weather seals. I have lubed the seals with gummy
fledge and it just rattles a few days later. Has anyone had any similar issues? I know the GS had a wider issue but haven’t seen much on the IS.

I had issues like that on my old Mk7 GTI. If I cleaned the seals and then rubbed them with silicone grease, the problem went away (not forever, mind you).

I haven't had any sunroof rattles on any IS I've owned. I've had 3 - a 2016, a 2021, and now a 2023. None of them ever rattled. Have you thought about taking it to the dealer?

yeah it’s definitely the seal somehow because when I open with moon roof it goes away. I was going to ask at the dealer but it’s just so hard to get a good experience from a dealer.

Mine doesn’t squeak (yet?) at 6,000 miles but I remember Gummi being the stuff all the BMW guys used for sunroof seals.

I got the same issue on my is350, which went away after I replaced it with a new seal.

Having the same issue but only when the sunroof is open going over bumps it rattles. How does replacing the seal resolve the issue?

not sure if it’s the same issue then, I’m only getting the issue when my sunroof is closed or up.

this guy explains it a lot but basically the seals harden and shrink causing some metal to metal contact.
