The 2025 Mercedes-Benz GLS-Class is the brand's flagship full-size luxury SUV, often dubbed the "S-Class of SUVs." It's a three-row, seven-passenger body-on-frame (though unibody for modern generations) SUV, first introduced as the GL-Class in 2006 (X164), becoming the GLS-Class with its second generation in 2016 (X166) and the current third generation in 2020 (X167). Key trims include the GLS 450, GLS 580, and the high-performance AMG GLS 63, with an expected starting price range from approximately $88,000 to over $150,000. Its opulent interior, advanced technology, and powerful engine options make it a standout choice for discerning luxury buyers.
The Good
The 2025 GLS-Class offers superb comfort with its spacious, luxurious cabin and air suspension, appealing to emotional desires for prestige and serenity. Practical buyers will appreciate its strong, refined performance across engine options, advanced safety features, and robust towing capacity. Its elegant design and cutting-edge technology further solidify its appeal as a premium, versatile family hauler.
The Bad
Prospective 2025 GLS buyers should anticipate its high initial purchase price and premium ownership costs, including maintenance and insurance. Fuel efficiency, while improved, remains a consideration for a large luxury SUV. The complex MBUX infotainment system can have a learning curve, and the third-row seating, while present, is best suited for children or short trips for adults.

What Problems Does the 2025 Mercedes-Benz GLS-Class Have?
Given that the 2025 Mercedes-Benz GLS-Class is a brand-new model year at the time of this writing, there are no "frequently reported problems" or recalls specific to this precise model year. Owners have not yet had sufficient time to report widespread issues.
However, we can infer potential long-term reliability concerns based on previous generations of the GLS (X167 and X166) and other Mercedes-Benz models with similar technology. Common themes across complex luxury vehicles, including the GLS, often include:
Mercedes-Benz typically addresses significant issues with technical service bulletins (TSBs) or recalls. For previous GLS generations (like 2020-2023), recalls have included issues ranging from rearview camera displays not showing, fuel pump failures, to seat belt malfunctions. Owners of a 2025 model should closely monitor official Mercedes-Benz communications and NHTSA recall notices as the vehicle ages. Proactive maintenance and adhering to service schedules are paramount for mitigating potential long-term issues in any luxury vehicle.
However, we can infer potential long-term reliability concerns based on previous generations of the GLS (X167 and X166) and other Mercedes-Benz models with similar technology. Common themes across complex luxury vehicles, including the GLS, often include:
- MBUX Infotainment Glitches: Early iterations of the MBUX system have occasionally experienced software bugs, slow responses, or connectivity issues. While Mercedes continuously refines this, complex systems always have a potential for minor electronic hiccups.
- Air Suspension Maintenance: The Airmatic or E-Active Body Control air suspension, while providing an incredibly smooth ride, can be costly to maintain or repair as components age. Leaks or compressor failures are not unheard of in high-mileage luxury SUVs.
- Electrical System Gremlins: Modern Mercedes vehicles are packed with sophisticated electronics. Issues like sensor malfunctions, battery drainage (especially related to the 48V mild-hybrid system), or infotainment system freezes have been reported on occasion in various models.
- Turbocharger or Engine Component Wear: While the engines are generally robust, high-performance V8s and turbochargers, particularly in AMG models, require diligent maintenance to ensure long-term durability. Neglecting oil changes or pushing the vehicle hard without proper cool-down can accelerate wear.
- Interior Material Durability: While luxurious, certain high-touch interior components, especially those with piano black trim or certain leathers, may show signs of wear, scratches, or creasing over extended use if not properly cared for.

Proactive maintenance and adhering to service schedules are paramount for mitigating potential long-term issues in any luxury vehicle.
How long will the 2025 Mercedes-Benz GLS-Class last?
Estimating average mileage or years of service for the 2025 Mercedes-Benz GLS-Class is based on its predecessors and brand reputation, as direct owner data isn't yet available. With proper, diligent maintenance, a GLS can reliably achieve 150,000 to 200,000 miles or more, often providing 10-15 years of service.
Long-term durability is generally good, reflecting Mercedes-Benz's engineering. However, high-end components like the air suspension, complex electronics, and sophisticated engine systems will inevitably require attention and significant investment as they age past 100,000 miles. Neglecting scheduled service is the quickest way to shorten its lifespan and encounter costly repairs. Weaknesses over time might include the wear and tear on suspension components, potential for electrical glitches in the advanced infotainment system, and the eventual need to replace expensive sensors or modules. Owners committed to authorized dealer service and preventative maintenance will see the best long-term results.

2025 Mercedes-Benz GLS-Class Prices and Market Value
The 2025 Mercedes-Benz GLS-Class commands a premium price when new, reflecting its luxury status and advanced features. Expected starting MSRPs are around $88,000 for the GLS 450, climbing to over $115,000 for the GLS 580, and exceeding $150,000 for the high-performance AMG GLS 63, before options and destination charges.
As the 2025 model year is new, there are no "current used market prices" for it yet. However, like most luxury vehicles, the GLS-Class experiences significant depreciation in its first few years. Expect a depreciation of 30-40% in the first three years. Factors affecting resale value include mileage, condition, optional packages (especially premium ones like the Executive Rear Seat Plus Package), maintenance history, and overall market demand. While it depreciates, its strong brand appeal and desirability mean it holds value better than some competitors, especially well-maintained, higher-trim models. Waiting 3-5 years for a used model can offer substantial savings.

2025 Mercedes-Benz GLS-Class Cost of Ownership

How Does the 2025 Mercedes-Benz GLS-Class Compare to Other Sport Utility Vehicle?
The 2025 Mercedes-Benz GLS-Class operates in the fiercely competitive full-size luxury SUV segment, directly challenging vehicles like the BMW X7, Audi Q7/Q8, Cadillac Escalade, Lincoln Navigator, and Range Rover.
Performance: The GLS offers a wide range of powerful engines, from the refined inline-six in the GLS 450 to the potent V8s in the GLS 580 and AMG GLS 63. It generally matches or exceeds the performance of its direct rivals like the BMW X7 (especially M60i) and Audi Q7/Q8 (especially SQ7/SQ8). The AMG GLS 63 is a performance beast, rivaling the BMW Alpina XB7. The Escalade and Navigator, while powerful, often prioritize comfort and straight-line torque over the GLS's more balanced, sporty-yet-luxurious ride dynamics.
Features: The GLS is packed with technology, highlighted by its dual 12.3-inch MBUX screens and extensive driver-assistance suite. Its interior opulence, material quality, and available massaging seats, E-Active Body Control, and executive rear seating are top-tier. The BMW X7 offers a similarly tech-rich and luxurious cabin. The Range Rover provides unparalleled off-road capability fused with luxury, and unique British charm. The Cadillac Escalade and Lincoln Navigator boast massive interiors and impressive Super Cruise/BlueCruise hands-free driving tech, appealing to those who prioritize sheer space and American luxury.
Reliability: Historically, Mercedes-Benz vehicles, including the GLS, are reliable when properly maintained, but their complex systems can lead to expensive repairs as they age. This is a common theme across all luxury German brands, including BMW and Audi. The Range Rover has historically faced more reliability scrutiny, while American rivals like the Escalade and Navigator generally have a reputation for robust powertrains, though still with modern electronic complexities.
Price: The GLS is priced competitively within its segment, typically starting slightly higher than the Q7 and X7 base models, and significantly less than a top-tier Range Rover. The AMG GLS 63 directly competes with the highest trims of the X7 and Range Rover. The Escalade and Navigator can often be optioned into a similar price bracket.
Recommendations:
The GLS stands out for its blend of classic Mercedes luxury, cutting-edge technology, and strong performance, making it a compelling choice for those prioritizing a well-rounded premium experience.

The 2025 Mercedes-Benz GLS-Class is ideal for affluent families or individuals who demand the utmost in luxury, comfort, technology, and performance from a full-size SUV. It caters to those who appreciate a prestigious brand image and a smooth, refined driving experience for long journeys.
Is it worth buying? Absolutely, for the right buyer. It offers an exceptional blend of attributes that justify its premium price tag for those who can afford it. However, it's crucial to understand the high long-term ownership costs associated with fuel, insurance, and maintenance.
Conditions for buying: Buying new offers the latest tech and full warranty. A GLS 450 new is excellent for a balance of power and efficiency. For performance enthusiasts, the AMG GLS 63 is unparalleled. If budget is a concern, waiting for a 2-3 year old certified pre-owned (CPO) model will significantly reduce initial depreciation, making the "S-Class of SUVs" a more attainable luxury. Ensure a thorough pre-purchase inspection and a robust maintenance plan for any used GLS to mitigate potential future repair costs.
