What's wrong?
The transmission wiring harness is a bundle of wires that carries electrical signals between the transmission controls and the rest of the vehicle. On the 2024 Mercedes-Benz E 350 and E 450, it should be routed with enough clearance from rotating driveline parts, including the drive shaft, so the insulation and connectors stay intact while the vehicle moves.
On recalled vehicles, a deviation in the development and production process left the harness too close to the drive shaft. As the drive shaft turns, contact can rub through the wiring. Damaged wiring can interrupt transmission controls and cause a loss of drive power.
There is no warning sign before the harness is damaged. If the failure occurs, the driver can see an instrument cluster message such as "Transmission Malfunction Stop," "Drive Malfunction Stop Restart Vehicle," "Drive Malfunction Stop Contact Dealer," or "Service Required Do Not Change Transmission Position."
Who's affected?
The E 350 and E 450 list separate wiring-harness part numbers, but both are tied to the same electrical-system wiring component.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific sedan is included.
What's the safety risk?
A loss of drive power increases the risk of a crash because the vehicle can stop responding to accelerator input in traffic. There is no advance warning before the failure. If a transmission or drive malfunction message appears, move out of traffic as safely as you can and call the dealer. Repair will be free at any franchised Mercedes-Benz dealer once available.
What should I do?
- Check your VIN to confirm your 2024 Mercedes-Benz E 350 or E 450 is included in this recall.
- Contact a franchised Mercedes-Benz dealer to ask whether the free transmission wiring harness routing check is open for your VIN.
- Schedule the routing check that moves the transmission wiring harness away from the driveshaft to prevent harness damage and loss of drive power.
- Bring the Mercedes-Benz owner notice if you have it. If not, reference recall number 24V224 when you call.
- Drive cautiously until the dealer checks the wiring harness, and move out of traffic if the vehicle loses drive power.
What happens at the repair
Mercedes-Benz has identified the dealer repair for this recall. Once available, a Mercedes-Benz technician will check the transmission wiring harness routing and correct the routing if it is too close to the driveshaft. The dealer repair will be free once available, with parts and labor 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 remain under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
