The 2021 Mercedes-Benz AMG G63 has 8 recalls, the most serious being a fuel pump that can shut down without warning, cutting drive power and raising the risk of a crash.
Two recalls address the rear door latches: the latch mechanism can fail to fully engage, leaving a door that looks closed but can swing open while driving. Prior repair attempts did not fully resolve this issue, and a follow-up recall covers vehicles where a replacement latch was installed during an earlier service visit. On the safety systems side, loose side crash sensor connectors can delay airbag and seatbelt deployment in a side impact, and seatbelt pretensioners on certain vehicles may not perform properly in a crash. A separate rear seatbelt issue affects child restraint use: the automatic locking retractors in the rear seats can deactivate too early, preventing a child safety seat from staying secured. A wiring harness near the front axle can chafe against an oil cooler and disable both anti-lock brakes and electronic stability control. There is also a recall covering the automatic emergency call system, which can fail to connect occupants with emergency services after a crash.
