The 2023 Mercedes-Benz AMG G63 has 4 recalls, the most serious involving a rear axle differential that can crack and fail, spilling oil onto the road or causing a sudden loss of drive power and handling — this recall affects only the special edition 4x4² trim.
The fuel pump can shut down without warning on certain vehicles, cutting engine power while driving and raising the risk of a crash. Prior repair attempts did not fully resolve the issue, which is why two separate campaigns address the same fuel pump behavior. On the climate control side, the air conditioning system may have been filled with the wrong refrigerant, which does not affect normal operation but poses a fire risk if the lines are ruptured in a crash.
