2021 Mercedes-benz G550 problems
The Mercedes-Benz G-Class, colloquially known as the G-Wagen (as an abbreviation of Geländewagen) is a four-wheel drive automobile manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. Originally developed as a military off-roader, later more luxurious models were added to the line. In certain markets, it was sold under the Puch name as Puch G until 2000.
The G-Wagen is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few passenger car vehicles to have such a feature.
Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of 44 years. Only the Unimog surpasses it. In 2018, Mercedes-Benz introduced the second-generation W463 with heavily revised chassis, powertrain, body, and interior. In 2023, Mercedes-Benz announced plans to launch a smaller version of the G-Class, named "little G"—though no definitive date was given for the launch.
The 400,000th unit was built on 4 December 2020.
The success of second-generation W463 led to the 500,000th unit milestone three years later in April 2023. The 500,000th model was a special one-off model with agave green paintwork, black front end, and amber turn signal indicators in tribute to the iconic 1979 press release photo of jumping W460 240 GD.

Common 2021 Mercedes-benz G550 problems
The 2021 Mercedes-Benz G550 has been reported to have several common problems based on complaints from owners. One of the most serious issues is the engine shutting down while driving, as described in a post on the MBWorld.org Forums. The owner of the vehicle reported that the car suddenly turned off during a drive, making it difficult to control the 6,000 lbs SUV and causing the driver to rely on hazard lights and wait for the car to come to a complete stop on its own. The engine yellow light remained on until the car was restarted, and the driver was shaken up by the experience. This issue was also reported to have happened earlier the same day when the car was parked for 8 hours and when attempting to stop for a red light.
Another common problem reported by owners is the fuel pump failing, as mentioned in a recall notice from the National Highway Traffic Safety Administration. This issue can result in a loss of drive power, increasing the risk of a crash. Dealers will replace the fuel pump free of charge for affected vehicles.
The door lock and window switch failure is also a common problem reported by owners of the 2021 Mercedes-Benz G550, according to RepairPal. This issue can cause the window to be stuck down or the door to only open from the inside, and it has been reported on G500s from 2002 through 2008 and G55 AMG SUVs from 2003 through 2010.
Additionally, oil level sensor or crankshaft position sensor failure has been reported by both regular G-Class SUVs and G Wagon tuned by AMG. These sensor failures can prevent the engine from running or cause a steady cloud of obnoxious smoke, and they can be expensive to fix.
Lastly, brake light switch failures have also been reported by owners of the 2021 Mercedes-Benz G550, causing the SUV to light up a warning light on the dashboard. This issue is relatively quick and easy for a technician or dealer to address.
These common problems with the 2021 Mercedes-Benz G550 can be frustrating and potentially dangerous for owners. It is important for owners to be aware of these issues and to have their vehicles inspected and repaired as necessary to ensure safe and reliable operation.
Is the G550 engine reliable?
Yeah they are reliable. It's a naturally aspirated V8 that's built like a truck. The G wagon has its own peculiarities like rattles from the hood (that can be fixed by taping the rubber stop at the front corner of the hood) and other small rattles, but they're great cars.
Are Mercedes G Wagons reliable?
The Mercedes-Benz G-Class is generally well-regarded for its durability, but like any vehicle, it can have some common issues. According to RepairPal, earlier models, particularly those from the mid-2000s, may experience electrical problems, including faulty window regulators and issues with the instrument cluster.
What is the gas mileage for a 2021 G550?
Those who can afford to own a G550 should have deep enough pockets to cover its propensity to swill gasoline. The EPA expects every model to earn 13 mpg in the city and 17 mpg on the highway.
