What's wrong?
The 12-Volt and 48-Volt ground connections on the 2024 Mercedes-Benz E 350 and E 450 are part of the electrical wiring harness. A ground connection gives electrical current a controlled return path through the vehicle body. These connections are held by fasteners, and the system depends on those fasteners being tightened to the specified torque.
On the recalled vehicles, a production rework deviation left certain ground connections below the required torque. A loose ground point creates extra electrical resistance. As current passes through that loose connection, heat builds at the connection instead of flowing cleanly through the circuit.
There is no warning sign before failure. When the issue occurs, the driver can see various warning messages in the instrument cluster. Treat those messages as a sign that the electrical system needs dealer inspection under this recall.
Who's affected?
Covers the E 350 and E 450, both tied to the same wiring nut.

What's the safety risk?
Overheated ground connections create a fire risk. There is no warning sign before the failure starts; after it starts, warning messages can appear in the instrument cluster. Treat any warning message as a reason to call the dealer and schedule the inspection soon. Repair is free at any franchised Mercedes-Benz dealer.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the 12-Volt and 48-Volt ground connections for the electrical wiring harness and repairs connections that are not secured properly. The recall repair is free, with parts and labor covered. Out-of-pocket repairs already paid are handled through the new vehicle warranty, not through a separate reimbursement program, because the involved vehicles remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
