2020 W213 squeaks and rattles
The most severe is the rear cargo cover. When installed it tends to be quiet for a while and then develops a really dramatic rattle. I can't find anything "loose" in it, but usually taking it off resolves the problem. Not a great solution as I really like to have my rear cargo area covered.
Even with the cargo cover removed there is a less dramatic rattling that occurs. I've taken out anything loose that I can find, including the little fold-up crate that is stored underneath the load floor. I feel like I can stimulate some noise by knocking on the headliner in the cargo area. Are there any commonly known "rattle points" back there?
Finally the driver's seat has an annoying squeak when driving even moderately aggressively. I'm sure this could be resolved with some grease; anybody know where I might apply this?
Thanks for any suggestions. I bought the car used and am trying to get the "new mercedes" experience out of it!




In my case, the weird thing was the noise seemed to be somewhere at the trunk area, I would never anticipated the rattle noise was the roof and sound just traveled downward (per se). Therefore, it would be recommended to tell the dealer to remove all trim panels, (top and side) and have another dealer technician ride in the back seats to listen for the noise. Sometimes, the wiring can rub against the trim panels too and causing the noise.
