Standard Sport Utility Vehicle 4WD
Fuel economy data from fueleconomy.gov (EPA / U.S. Dept. of Energy). Annual cost based on 15,000 mi/yr at 55% city driving and current fuel prices. MPG is U.S. gallons; L/100km converted.
The 2019 Mercedes-Benz AMG G63 has 8 recalls, the most serious being two separate fire risks: a fuel injector leak and a turbocharger oil feed line that can drip oil onto hot engine or exhaust components.
The door latch system has two related recalls. The rear door latch can fail to fully engage, leaving the door appearing closed while it can swing open during driving. A prior repair attempt using a replacement latch did not fully resolve the issue, and certain vehicles that received that replacement part are covered by a second recall addressing the same consequence on the right-side rear door. On the chassis electronics side, the front axle wiring harness can chafe against the oil cooler and wear through its insulation, cutting out anti-lock brakes and electronic stability control. A separate recall covers a software condition that can also deactivate stability control and anti-lock brakes without warning. Finally, the automatic emergency call system has two recalls: in one case it may not connect to emergency services at all, and in another it can transmit the wrong location to dispatchers after a crash.
