The Good
The 2018 G-Class boasts impressive off-road performance and a powerful engine, appealing to practical buyers. Emotionally, its iconic design and luxurious interior offer a sense of prestige and exclusivity. Comfort is high, and its rugged build suggests reasonable reliability. However, fuel efficiency is low. It offers a unique blend of capability and luxury, albeit at a premium price.
The Bad
The 2018 G-Class suffers from poor fuel economy, a bouncy ride on paved roads due to its solid axles, and limited cargo space compared to other SUVs in its price range. Potential buyers should watch out for electrical issues and ensure regular maintenance has been performed, as repairs can be expensive. The infotainment system can also feel dated compared to newer models.

Analysis
What Problems Does the 2018 Mercedes-Benz G-Class Have?
Recalls for the 2018 model year have been relatively infrequent, but it's always advisable to check the NHTSA (National Highway Traffic Safety Administration) website for the latest recall information.
Long-term reliability is a mixed bag. The G-Class's body-on-frame construction and robust drivetrain suggest durability, but the complex electronics and luxury features can be prone to failure over time, particularly as the vehicle ages. Owners should pay close attention to regular maintenance, especially fluid changes and inspection of the suspension and braking systems. Rust can also be a concern in regions with harsh winters and salted roads, so rustproofing is recommended. Given the relatively low production volume, specific model-year issues might be less prevalent, but thorough pre-purchase inspection is essential, particularly checking for oil leaks and any signs of corrosion, to minimize potential issues. Some early models experienced issues with fuel pumps and sensors, making comprehensive diagnostics a key step before purchase.

What Technology & Safety Features are Included?
Optional features included adaptive cruise control, which maintains a set distance from the vehicle ahead, and upgraded audio systems.
Safety features include multiple airbags, electronic stability control, and anti-lock brakes. While the 2018 G-Class wasn't specifically crash-tested by IIHS (Insurance Institute for Highway Safety) or NHTSA in its original form, its robust construction provides a sense of security. However, its high center of gravity and solid axles can affect handling in emergency maneuvers. Later redesigned models (2019+) achieved better crash test scores, but the 2018 model relied more on its inherent build quality and safety systems than modern crash-test performance. The inclusion of features like blind-spot monitoring enhances safety, especially given the limited visibility due to the G-Class's design. The technology suite is relatively dated compared to newer vehicles, but it covers the essential aspects of safety and entertainment.

How Does the 2018 Mercedes-Benz G-Class Compare to Other Sport Utility Vehicle?
In terms of price, the G-Class is at the higher end of the spectrum.
Alternatives: The Lexus LX 570 is a more reliable and practical choice. The Range Rover offers a more luxurious on-road experience. The Cadillac Escalade provides superior space and comfort. However, none offer the G-Class's unique blend of off-road capability and iconic styling. If reliability is paramount, the Lexus is the better choice. For a more modern and comfortable SUV, the Range Rover or Escalade might be preferable. But if status and unmatched off-road ability are the priority, the G-Class remains a compelling choice.
