I just got my C43 2 weeks ago, now that the weather is getting nice and I put the windows down for the first time, the seals are squealing against the moving glass like crazy. Has anyone else had this issue? It is a CPO 2018 with only 21,000km so I assume I can go to the dealer for this. I also seem to have the skipping windshield wipers which it seems like there is no real fix for.

Put a few drops of Mercedes Sliding Compound in the window channels and raise / lower the windows a few times - should do the trick. As far as the chattering wipers, try swapping out from the OE wipers to Bosch Aerotwins.

Mine squeaked like no tommorow when I first got her. Dealer put some of those and it's been good for over a year.
