Mercedes-Benz filed this with NHTSA as a service campaign dated Jun 14, 2024, received Jul 8, 2024, about the suspension. It names 3 model years across Mercedes-Benz and Mercedes-Maybach (2020–2021).

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 163 complaints with NHTSA since 2015.
The suspension has failed despite changing engine mounts. It is available for inspection if needed. I also believe there is Premature wear of the front struts and rear shock absorbers. This can affect vehicle handling and control, increasing the risk of a crash.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.
