What's wrong?
The front door wiring harness on the 2019 G 550 and G63 is the bundle of wires that runs from the body of the SUV into each front door. It carries the electrical signals that control the airbag system, the window switches, the door locks, the speakers, and other functions inside the door. The harness has to flex every time the door opens and closes, so it is routed through a protected channel between the door and the body.
On affected G-Class SUVs, the harness was routed in a way that puts individual wires in the path of the door's motion. Each time the front door opens or closes, the movement pulls or pinches the wiring. Over time, the insulation wears through and the wire underneath can break or short out.
There is no warning sign before failure. When a wire finally gives way, a warning message appears in the instrument cluster, and the function tied to that wire stops working. The specific message depends on which wire was damaged.
Who's affected?

What's the safety risk?
Damaged front door wiring can disable the side impact restraint system, prevent the doors from unlocking automatically after a crash, or block the emergency call function from sharing the vehicle's location. Each failure increases the risk of injury in a crash. There is no advance warning before the wiring fails, though a warning message in the instrument cluster will appear once a function is affected. Repair is free at any franchised Mercedes-Benz dealer.
What should I do?
- Check your VIN to confirm your 2019 Mercedes-Benz G 550 or G63 is included in this recall.
- Contact your nearest franchised Mercedes-Benz dealer to schedule the front door wiring harness inspection and repair.
- Ask the dealer to inspect, modify, or replace the front door wiring harness that protects the side impact restraint, automatic door unlocking, and emergency call features.
- Reference recall number 19V820 when you call, and bring the owner notice if Mercedes-Benz has mailed one.
- Call Mercedes-Benz customer service at 1-800-367-6372 with any questions about scheduling or the repair.
What happens at the repair
At the dealer, a Mercedes-Benz technician inspects the front door wiring harness on both front doors and modifies or replaces it if the wires show damage from the door opening and closing. Parts and labor are free under the recall. Out-of-pocket repairs already paid are handled through the existing new-vehicle warranty, not through a separate reimbursement program, since the affected G-Class vehicles are still under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
