Small issue but it is a bit of a pest. I got my 2019 c63 about a week ago and I noticed that for some reason the driver seat belt doesn’t seem to fully retract. What I mean by that is there is a decent amount of slack in the seatbelt when I take it off which caused me to jam the door on it. What is weird is usually by the time I get back in the car the slack seems to have gone away?? I never experienced this in my 2020 c300.

anyone else experience this?

I had the same issue with my Coupe. I washed the seat belt with warm water and soap and its back to new !

I had the same issue. It's a known issue with the seat belt presenter in the coupes. They adjusted the mechanism under warranty and it's been fine since.

I also had the exact same issue, so much so that the outer side bolsters of my bucket seats were actually pealing from the slack buckle hitting it every time I unbuckle. I took it to my dealership and they fixed it under warranty
