What’s wrong with it?
Oil leaking onto the roadway may cause a road hazard for following traffic. Rear axle failure can result in a sudden loss of handling or drive power. Either of these conditions can increase the risk of a crash.
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2022-2023 AMG G63 special edition 4x4² (squared) vehicles.
The rear axle differential housing may develop cracks, possibly resulting in oil leaking onto the roadway or axle failure.
