What's wrong?
The front axle wiring harness on 2019-2021 Mercedes-Benz AMG G63 and G 550 vehicles carries electrical signals near the front axle. Those signals help systems such as anti-lock brakes and electronic stability control read what is happening at the wheels and respond when traction or braking control is needed. The harness has to stay routed and protected as nearby parts move, heat up, and vibrate.
On affected vehicles, the harness runs through a narrow area near the auxiliary oil cooler. Because of a development-process issue, the harness can touch the oil cooler and rub against it during normal use. That chafing damages the wiring, and damaged signal wires can lead to a loss of anti-lock brake and electronic stability control function.
If the failure happens, the driver is warned by an indicator lamp or a warning message in the instrument cluster. Treat that warning as a sign that the brake-control wiring needs dealer inspection.

What's the safety risk?

- Check your VIN to confirm your 2019-2021 Mercedes-Benz AMG G63 or G 550 is included in this recall.

- Bring the recall notice if you have it. If not, reference recall number 23V097 when you call.
