What's wrong?
The transmission electrical wiring harness in the 2022-2023 Mercedes-Benz C 300 and AMG C43 carries electrical signals between transmission parts and the vehicle computers. Those signals help the transmission select and hold the right gear. The harness has to fit with the right length so it stays routed away from moving parts.
On affected vehicles, a supplier production deviation left certain harnesses outside the specified length tolerance. That wrong length can place the harness too close to the front drive shaft, where it can rub while the vehicle is driven. If the harness is damaged, transmission signals can be interrupted, which can lead to an unintended shift into neutral or a loss of drive power.
There is no warning sign before failure. If the problem happens, the driver can see messages such as "Transmission Malfunction Stop," "Drive Malfunction Stop Restart Vehicle," "Drive Malfunction Stop Contact Dealer," or "Service Required Do Not Change Transmission Position" in the instrument cluster.
Who's affected?
The scope splits between C 300 sedans in 2022 and 2023 and AMG C43 sedans in 2023, all tied to transmission electrical wiring harnesses.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the transmission wiring harness routing and repairs the routing if damage or interference is found. 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, since the involved vehicles remain under warranty and were not previously subject to this condition. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
