What's wrong?
The transmission wiring harness on the 2019-2022 Mercedes-Benz AMG GT53, AMG E53, AMG CLS53, and AMG GT43 carries electrical signals and power near the transmission. The connector at the end of that harness has to stay sealed so moisture and road contamination stay out of the circuit.
On affected vehicles, the harness was routed with too much tension during production. That tension can pull back the wire insulation at the connector, leaving the seal unable to do its job. Once the connector is exposed, corrosion can form, and the damaged connection can create an electrical short-circuit.
Before the short-circuit happens, the driver can see a yellow battery indicator lamp for the charging system, a 4Matic malfunction warning message, or both in the instrument cluster. Those warnings mean the electrical system has detected a problem and the vehicle needs dealer attention.

What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the transmission wiring harness electrical connector and repairs it if needed. The technician also reroutes the harness and installs an additional bracket so the connector is better protected from corrosion. Parts and labor are covered under the recall. Mercedes-Benz uses its general reimbursement plan for this campaign, so documented out-of-pocket repairs tied to this issue can be submitted for review. Bring prior repair paperwork to the service desk.
