What's wrong?
The rear seat belt buckle on the 2022-2023 Mercedes-Benz Eqs 580, Eqs 450, and EQS450 is the latch point that holds the belt tongue beside the rear seat. It is fastened to the vehicle body with a cylinder screw with flange, a bolt designed to keep the buckle anchored when the belt loads in a stop or crash.
In NHTSA campaign 23V464, the problem is the bolt torque on certain rear buckle connections. During production rework, the bolts that secure the buckles did not meet the required torque specification. A loose buckle connection can let the seat belt anchor move instead of holding the occupant restraint in its intended position, so the rear belt system does not perform as designed.
There is no warning sign before failure. The driver will not receive a dashboard warning or message because the issue is a hidden bolt connection, not an electronic fault.
Who's affected?
Covers Eqs 580, Eqs 450, and EQS450 across the 2022 and 2023 model years, all with the same rear seat belt buckle assembly.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the rear seat belt buckle bolts and secures any bolts that were not properly fastened to the vehicle body. Parts and labor are covered under the recall. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remained covered by warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
