Summary
The Mercedes-Benz G 550 has 7 recalls spanning 2019 through 2025, with the most serious being a fuel tank weld defect on 2019 models that can allow fuel to leak and, near an ignition source, start a fire.
The next most urgent issue for 2019 owners involves the front door wiring harnesses, which can be routed in a way that damages wires as the doors open and close, potentially disabling side airbags, automatic door unlocking in a crash, or the vehicle's location tracking. Also affecting 2019 through 2021 models, the rear door latches can fail to fully engage, leaving the door appearing closed while it can swing open while driving. On 2019 and 2020 vehicles, the electronic stability control and anti-lock brakes can deactivate unexpectedly, removing key crash-avoidance systems, and the child safety lock embossing on the rear doors can indicate the wrong lock position, meaning a child could open the door without warning. Moving to the 2022-2023 model years, certain vehicles left the factory with the wrong refrigerant in the air-conditioning system, which can leak and raise the risk of fire in a crash. On 2025 models, the electronic stability control warning light can display incorrectly during a system failure, leaving the driver without a reliable alert that stability control is compromised.
