What's wrong?
The transmission wiring harness on the 2019-2023 Mercedes-Benz AMG CLS53, AMG E53, AMG GT53, and AMG GT43 carries electrical signals to and from the transmission area. Its connector is supposed to stay sealed so water and road splash do not reach the terminals while the drivetrain moves and heats up.
On affected vehicles, that connector was not sealed enough for normal temperature changes and dynamic water exposure. Some vehicles also had the harness connection wired incorrectly during production or during the prior recall repair. Moisture can reach the connector, corrosion can build on the terminals, and that corrosion can lead to an electrical short-circuit.
Before a short circuit happens, the driver can see a yellow battery indicator lamp or a "4MATIC malfunction" message in the instrument cluster. Treat either warning as a sign that the transmission wiring harness connector needs dealer inspection.
Who's affected?
All listed AMG CLS53, AMG E53, AMG GT53, and AMG GT43 cars share the same electrical wiring harness component.

What's the safety risk?
An electrical short circuit raises the risk of a fire. Before that happens, the yellow battery indicator lamp or a 4MATIC malfunction warning message can appear in the instrument cluster. Treat either warning as a reason to pull over safely and call a Mercedes-Benz dealer. Repair will be free at any franchised Mercedes-Benz dealer once Mercedes-Benz opens it.
What should I do?
- Check your VIN to confirm your 2019-2023 Mercedes-Benz AMG CLS53, AMG E53, AMG GT53, or AMG GT43 is included in this recall.
- Wait for Mercedes-Benz to open the final dealer repair before scheduling the wiring-harness and connector replacement that fixes the corrosion-related short-circuit risk.
- Contact a franchised Mercedes-Benz dealer if you have questions about interim safety guidance before the final repair opens.
- Call Mercedes-Benz customer service at 1-877-496-3691 with questions and reference recall number 24V445 when you call.
- Keep the prior recall paperwork if your vehicle was repaired under recall 22V-533; Mercedes-Benz says those vehicles still need the new remedy.
What happens at the repair
Because the campaign is still in interim status, Mercedes-Benz has notified owners of the safety risk and will send a second notice when the final repair opens. Once available, a Mercedes-Benz technician will replace the two-part transmission wiring harness and connector. Parts and labor are covered by the recall. MBUSA also plans to notify owners about reimbursement before the recall notice because some vehicles were previously exposed to this condition. Keep related repair paperwork so you can follow MBUSA's reimbursement instructions when they arrive.
