The 2020 Mercedes-Benz AMG G63 has 7 recalls, the most serious being rear doors that may appear fully closed but are not latched, allowing them to swing open while driving.
The door latch issue has a layered history: an earlier recall addressed the same rear door latch problem, but vehicles that received a replacement latch during that prior repair may still have a defective component in the right-side rear door. Two recalls affect the stability and braking systems: the front axle wiring harness can chafe against an oil cooler and wear through its insulation, cutting power to the anti-lock brakes and electronic stability control, and a separate software or sensor issue can also deactivate those same systems. Loose side crash sensor connectors can delay airbag and seatbelt activation in a side impact, reducing occupant protection at the moment it is most needed. Finally, the automatic emergency call system has two recalls: in one case it may fail to connect to emergency services at all, and in another it may report the wrong location to first responders after a crash.
