The Mercedes-Benz GLS-Class, tracing its roots back to the GL-Class, is the brand's flagship SUV. The 2022 GLS-Class, a full-size luxury SUV, offers a spacious three-row configuration. Key trims include the GLS 450, GLS 580, and the high-performance AMG GLS 63. Pricing ranges from approximately $77,000 to over $130,000. Its blend of luxury, space, advanced technology, and powerful engine options make it popular for families seeking a premium SUV experience. It stands out due to its opulent interior and smooth ride.
The Good

The 2022 Mercedes-Benz GLS-Class offers impressive performance, particularly in the AMG variants. Comfort is a major selling point, with a plush ride and luxurious interior. The design exudes sophistication and prestige, appealing to emotional buyers. Practical advantages include ample cargo space and available advanced safety features. While not the most efficient, it provides a smooth, powerful driving experience.

The Bad

The 2022 Mercedes-Benz GLS-Class can be expensive to maintain, and some owners have reported issues with the complex electronics. The third-row seating, while present, is best suited for smaller adults or children. Fuel economy is not a strong point, especially with the more powerful engine options. Consider extended warranty options to mitigate potential repair costs.

Analysis

What Problems Does the 2022 Mercedes-Benz GLS-Class Have?

While the 2022 Mercedes-Benz GLS-Class generally enjoys a positive reputation, some frequently reported problems include issues with the MBUX infotainment system, such as software glitches and connectivity problems. Some owners have reported minor electrical issues, such as sensor malfunctions and problems with the adaptive air suspension. Check engine lights and related sensor failures have also been mentioned, though not as common as MBUX issues.

Recalls for the 2022 GLS-Class should be checked on the NHTSA website using the VIN. Recalls can address a variety of safety-related concerns. Long-term reliability is a consideration, as with any luxury vehicle with complex systems. The air suspension, in particular, can be prone to issues over time, leading to potentially expensive repairs. Extended warranties are often recommended to mitigate the risk of high repair costs as the vehicle ages.

Earlier model years of the GLS (and its predecessor, the GL-Class) had reports of oil leaks and transmission issues, but these appear to be less prevalent in the 2022 model. It's always a good idea to have a pre-purchase inspection performed by a qualified mechanic familiar with Mercedes-Benz vehicles to identify any potential issues before buying a used GLS-Class.

How long will the 2022 Mercedes-Benz GLS-Class last?

With consistent and proper maintenance, a 2022 Mercedes-Benz GLS-Class can realistically provide 150,000 to 200,000 miles or 10-12 years of service. Key to longevity is adherence to the manufacturer's recommended maintenance schedule, including regular oil changes, fluid checks, and timely replacement of wear items.

Long-term durability weaknesses often revolve around the air suspension system, which can require costly repairs as the vehicle ages. Electronic components, including the MBUX system, may also exhibit issues over time. Preventative maintenance is crucial for maximizing the lifespan and minimizing potential problems.

What Technology & Safety Features are Included?

The 2022 Mercedes-Benz GLS-Class boasts a comprehensive suite of technology, entertainment, driver-assistance, and safety features. Standard features include the MBUX infotainment system with dual 12.3-inch displays, Apple CarPlay and Android Auto compatibility, navigation, and a premium sound system. Driver-assistance features include blind-spot monitoring, lane-keeping assist, adaptive cruise control, and automatic emergency braking.

Optional features expand the technological capabilities, adding features like a head-up display, augmented reality for navigation, a surround-view camera system, and advanced driver-assistance systems like active lane-change assist and evasive steering assist. The entertainment options can be enhanced with a rear-seat entertainment system with dual screens.

Safety is a priority, with multiple airbags, stability control, and anti-lock brakes as standard. The GLS-Class often receives high crash-test ratings from the NHTSA and IIHS, but it's recommended to check the latest ratings specific to the 2022 model year on their respective websites. These ratings typically consider frontal, side, and rollover crash tests, as well as evaluations of driver-assistance technologies. The combination of advanced safety features and robust construction contribute to the GLS-Class's strong safety profile.

2022 Mercedes-Benz GLS-Class Prices and Market Value

When new, the 2022 Mercedes-Benz GLS-Class had a starting MSRP around $77,000 for the GLS 450, climbing to over $130,000 for the AMG GLS 63. Current used market prices vary based on mileage, condition, and trim, but expect to find GLS 450 models in the $60,000-$75,000 range and AMG models significantly higher.

Depreciation is typical for a luxury SUV; however, the GLS-Class holds its value reasonably well compared to some competitors, especially if well-maintained and equipped with desirable options. Lower mileage, a clean Carfax report, and popular features like the Premium Package all positively impact resale value. Higher trims like the AMG also tend to depreciate less percentage-wise.

2022 Mercedes-Benz GLS-Class Cost of Ownership

The 2022 Mercedes-Benz GLS-Class is a costly vehicle to own long-term. Insurance premiums are relatively high due to its luxury status and repair costs. Fuel expenses can be significant, especially with the V8 engines. Maintenance, including scheduled services and potential repairs, can be expensive due to the specialized parts and labor required. While the GLS-Class provides a luxurious experience, it is not an economical choice and requires a considerable financial commitment to own and maintain.

reasonable repair costs.

How Does the 2022 Mercedes-Benz GLS-Class Compare to Other Sport Utility Vehicle?

The 2022 Mercedes-Benz GLS-Class competes with other full-size luxury SUVs like the BMW X7, Cadillac Escalade, Land Rover Range Rover, and Lincoln Navigator. In terms of performance, the AMG GLS 63 stands out with its potent engine, rivaling the Range Rover Sport SVR. The BMW X7 offers a similar blend of luxury and performance, while the Cadillac Escalade provides more space and a bolder design.

Regarding features, the GLS-Class is well-equipped with advanced technology, but the Escalade offers innovative features like Super Cruise. Reliability is a mixed bag; the GLS-Class has its share of reported issues, while the BMW X7 has a similar reputation. The Lincoln Navigator often scores higher in initial quality surveys.

Price-wise, the GLS-Class is competitive within its segment. The Escalade and Navigator can offer more value for money, depending on trim level. A similar alternative would be the BMW X7, offering comparable luxury and performance. The Range Rover offers a more rugged and off-road capable option, while the Genesis GV80 (though smaller) presents a compelling value proposition with similar luxury at a lower price point. Choosing the "best" depends heavily on individual priorities.

Final Verdict: Is the 2022 Mercedes-Benz GLS-Class a Good Sport Utility Vehicle?

The 2022 Mercedes-Benz GLS-Class is ideal for affluent families seeking a luxurious and spacious three-row SUV with advanced technology and strong performance. Whether it's worth buying depends on your budget and priorities. A used GLS 450 can represent good value, offering the core luxury experience at a lower price point.

However, be prepared for potentially higher maintenance costs. Buying new allows you to customize the vehicle and benefit from the factory warranty, but comes at a significant premium. Consider an extended warranty, especially for used models, to mitigate potential repair expenses. If reliability is a major concern, exploring alternatives like the Lincoln Navigator or Lexus LX might be prudent. The GLS is a great vehicle, but careful consideration of ownership costs is essential.
