The Mercedes-Benz G-Class, a legendary SUV with roots tracing back to the 1970s military vehicle, received a significant redesign in 2019, carrying over into the 2020 model year. This luxury SUV is available in a distinctive boxy body style. Key trims include the G 550 and the high-performance AMG G 63. The 2020 G-Class initially ranged from roughly $130,000 to over $170,000.

What Problems Does the 2020 Mercedes-Benz G-Class Have?

While the 2020 Mercedes-Benz G-Class benefits from its redesign, some frequently reported problems and long-term reliability concerns exist. Issues with the infotainment system, including glitches and unresponsive screens, have been noted. Some owners have reported electrical issues related to the various driver-assistance features. Occasional problems with the air suspension system, specifically on the AMG G 63, have also surfaced. While not widespread, some owners have mentioned minor oil leaks. Early production models of the redesigned G-Class (2019 and 2020) exhibited some quality control issues, such as misaligned trim pieces or inconsistent paint application.
Recalls for the 2020 G-Class have been relatively infrequent, but it's essential to check the NHTSA website for the latest recall information specific to your VIN. Long-term reliability can be influenced by the complexity of the vehicle's systems. The twin-turbo V8 engines require regular maintenance, and turbocharger issues can be costly to repair. The advanced driver-assistance systems, while beneficial, also add complexity and potential failure points. Overall, while the G-Class is robustly built, its intricate technology and performance-oriented components can contribute to higher long-term maintenance costs and potential for issues.

How long will the 2020 Mercedes-Benz G-Class last?

With proper maintenance, a 2020 Mercedes-Benz G-Class can reasonably be expected to provide 150,000 to 200,000 miles of service, potentially lasting 10-15 years. Adhering to the recommended maintenance schedule, using high-quality fluids, and addressing minor issues promptly are crucial. Long-term durability depends heavily on how the vehicle is used; frequent off-road excursions can accelerate wear and tear. Weaknesses over time tend to involve the air suspension, electrical components, and potential for turbocharger issues. Regular inspections and proactive maintenance are key to maximizing longevity.

What Technology & Safety Features are Included?

The 2020 Mercedes-Benz G-Class boasts a comprehensive suite of tech, entertainment, driver-assistance, and safety features. The COMAND infotainment system features a 12.3-inch display, navigation, Apple CarPlay, and Android Auto. The standard sound system is excellent, with optional Burmester surround-sound systems available. Driver-assistance features include adaptive cruise control, blind-spot monitoring, lane keeping assist, parking sensors, and a rearview camera.
Optional features include a 360-degree camera, massaging front seats, and upgraded leather upholstery. The G-Class prioritizes safety with features such as automatic emergency braking, forward collision warning, and crosswind assist. However, due to its unique body-on-frame construction and limited production volume, the G-Class is not typically crash-tested by the NHTSA or IIHS. Despite the lack of official ratings, the G-Class incorporates numerous safety technologies designed to protect occupants. The high seating position also provides excellent visibility. The robust construction and advanced safety systems contribute to a secure driving experience.

2020 Mercedes-Benz G-Class Prices and Market Value

The 2020 Mercedes-Benz G-Class had a starting MSRP of around $130,900 for the G 550 and approximately $150,000 for the AMG G 63 when new. Used market prices in 2024 typically range from $100,000 to $150,000, depending on mileage, condition, and options. The G-Class exhibits relatively low depreciation due to its strong brand image, limited production, and high demand. Factors affecting resale value include mileage, condition, service history, and the presence of desirable options. The AMG G 63 trim generally holds its value better than the G 550.

2020 Mercedes-Benz G-Class Cost of Ownership

The 2020 Mercedes-Benz G-Class is a costly vehicle to own. Insurance premiums are high due to its value and repair costs. Fuel economy is poor, resulting in significant fuel expenses. Maintenance, including oil changes and specialized service, can be expensive. Repairs, especially for the engine, transmission, or electronics, can be substantial. Long-term ownership costs are considerably higher than average due to these factors. It is not an economical vehicle to own.

2020 Mercedes-Benz G-Class Insurance

Insurance for a 2020 Mercedes-Benz G-Class is moderately priced, reflecting its status as a Minivan with strong safety ratings and
reasonable repair costs.

How Does the 2020 Mercedes-Benz G-Class Compare to Other Minivan?

The 2020 Mercedes-Benz G-Class competes with other high-end SUVs such as the Land Rover Range Rover, Cadillac Escalade, and Porsche Cayenne. In terms of off-road performance, the G-Class and Range Rover are comparable, though the G-Class prioritizes ruggedness over the Range Rover's luxury focus. The Escalade offers more interior space and a lower price point, but lacks the G-Class's off-road capability and prestige. The Cayenne provides sportier on-road handling but is less capable off-road.
The G-Class offers unique styling and a strong brand image that rivals struggle to match. Reliability can be a concern compared to the Lexus LX, which is known for its dependability. If off-road capability isn't a primary concern, the Porsche Cayenne or BMW X7 offer similar luxury and performance with potentially lower running costs. The Range Rover presents a similar blend of luxury and off-road ability, albeit with its own reliability considerations. For those prioritizing space and value, the Cadillac Escalade or Lincoln Navigator are alternatives, but they lack the G-Class's unique character.

Final Verdict: Is the 2020 Mercedes-Benz G-Class a Good Minivan?

The 2020 Mercedes-Benz G-Class is ideal for buyers seeking a status symbol with genuine off-road capability and a luxurious interior. It's worth buying if you appreciate its iconic design and are willing to accept its high running costs and potential reliability concerns. Consider buying used to mitigate depreciation, but thoroughly inspect the vehicle's service history. The AMG G 63 offers enhanced performance but at a higher price. Ensure that any potential purchase has been well-maintained and free of major issues. If off-roading isn't a priority, consider alternatives like the Porsche Cayenne or BMW X7 for a more balanced experience.

Strongest SUV with Amazing Drive, Power & Presence

Truly a Beast! Owning and driving multiple exotic and luxury vehicles; nothing beats G63. Absolute Power, Style, Drive and Road presence. No wonder why there is a 7-8 months wait time and one of the most sought after vehicle. New G63 platform is super stable, great handling, luxurious (mayback class) still maintaining 1972 Battle Field rugged looks. I can go on and on...

Most comfortable car i've ever owned

The old G-Class was an utter liability, especially the G63, almost lethally unstable and unable to cope with the demands placed upon it by the rampant engine. The new one is a… revelation. I can’t believe the transformation. OK, it’s not a Range Rover, there’s still a trace of ladder fame shudder and shimmy on rough roads, but the ride, the steering, the drivability – it’s on another level. Here’s a two-metre tall, 2.5-tonne SUV that can actually be driven with some verve. No longer will you set out for a long trip with trepidation, no longer will corners petrify. You used to be able to swing the steering over a wide arc in the old recirculating ball-equipped car, and nothing would happen. Don’t try that now. You’ll actually change direction. There’s proper rack and pinion steering and although the type of people who wear camo trousers might loathe the loss of the front beam axle (independent driveshafts now drop out of either side of the front differential casing), the new-found composure and trust is a revelation. The front end has grip, the roll is way better managed than you expect and the G63 engine… I’m still not sure it’s necessary for the G63 to be this fast. 0-62mph in 4.5secs is bonkers, but there’s now less disparity between the acceleration, handling and brakes. The advantage still lies with the engine, and it’s hard to resist its charms, either the hoof-in-the-back acceleration or the accompanying V8 rumble and roar from the side exit pipes. It is ballistically fast in a way something that weighs 2,485kg probably shouldn’t be. At least the brakes do what they’re supposed to now. That’s new, too. So on-road it has the composure and manners that may not better a Range Rover in terms of smoothness and silence, but do at least make it a realistic alternative. And off-road it can do things that are literally unbelievable. Pressing the centre diff lock button changes the modes from road settings - Comfort, Sport, Eco (!), Individual - to G-Mode, which can be left to do its own thing, or you can pick from Sand, Trail and Rock positions, where the settings of the suspension stiffness, steering weight and engine are adapted accordingly. But it’s what happens when you lock the rear and front differentials and select low range that’s uncanny. The G-Class becomes unstoppable, you just point it at stuff, take it slow and all that torque meters itself out in an entirely different and much more precise way. It is imperious off-road, feels ultra-durable and tough.The cabin has improved almost as much as the road manners. The old one was hopelessly cramped front and back and the environment was utilitarian. Now there’s actual elbow and knee room and an extra 150mm of legroom in the back. If that suggests it’s now class-leading… it’s not, it’s just that is was terribly small before. The high floor still means the seating position in the back isn’t particularly relaxing and if you open the side-hinged tailgate you’ll find the boot is probably a bit smaller than you expect as well. The downside of a ladder-frame chassis is that it’s not anything like as space efficient as a modern monocoque. But Merc has done a great job of tarting this one up into something relatively glamorous, something that’s going to appeal to its urban audience. The dash employs the S-Class’s twin 12-inch screens, and thoroughly modern infotainment and functionality, up to and including a 15 speaker, 590-watt Burmester sound system. Rear visibility isn’t great, but the upright pillars, slab sides and visible bonnet actually make the G-Class easy to place for manoeuvring. That can be your excuse when your friends ask why you’ve bought a G-Class when you never drive outside the M25. Couple more things. Apparently G-Class owners were so wedded to some of the old car’s features that Mercedes has had to engineer them into the new one, too. Specifically the door slam and door lock noises. Once heard, never forgotten. Especially the latter, if only because of its volume…

G550 MBZ on April 4, 2020

Built like a TANK

Incredible build quality inside and out, like a Rolls or Bentley. Smooth ride with 20" wheels. Feels very safe . Excellent visibility. Best stereo I have ever heard. Fantastic multicontour front seats Some wind noise at higher speeds, not as efficient as GLS, slightly truck like.
