What's wrong?
The rear axle differential on the 2022-2023 Mercedes-Benz AMG G63 sends engine power to the rear wheels and lets the left and right wheels turn at different speeds in corners. Its housing is the metal case around the gears and oil. That case has to hold the gears in position and keep the lubricant sealed inside.
In NHTSA campaign 23V851, Mercedes-Benz says the rear axle differential housing on affected AMG G63 vehicles does not meet strength requirements. That weakness can let the housing crack. Once the case cracks, differential oil can leak onto the roadway, and the rear axle can fail if the damage progresses.
There is no warning sign before failure. Mercedes-Benz says the driver will not receive a warning because of the failure mechanism, so the VIN check and dealer instructions matter more than waiting for a noise, light, or handling change.
Who's affected?

What happens at the repair
Do not drive the vehicle until the recall repair is complete. Ask Mercedes-Benz customer service or the dealer about towing to an authorized Mercedes-Benz dealer before the vehicle moves. At the dealer, a Mercedes-Benz technician completes the rear axle differential housing recall repair and applies the new remedy required for vehicles that already had the earlier recall work. Parts and labor are covered under the recall. 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. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
