The 2026 Mercedes-Benz GLS-Class, continuing its legacy as the flagship of Mercedes-Benz's SUV lineup, is a full-size luxury SUV renowned for its opulent interior and advanced technology. Available across various model years, key trims typically include the GLS 450, GLS 580, and the high-performance AMG GLS 63. With a starting price generally in the mid-$80,000s, its popularity stems from its exceptional comfort, spaciousness for up to seven passengers, and the prestigious Mercedes-Benz badge.
The Good
The GLS-Class boasts a commanding presence, refined ride, and a lavish cabin that appeals to the senses. Practically, it offers impressive passenger and cargo versatility, robust performance across its engine options, and the long-term reliability associated with the Mercedes-Benz brand.
The Bad
Potential owners should be aware of the GLS-Class's substantial curb weight, which can impact agility. Some find the infotainment system's complexity a learning curve, and the premium pricing, while reflective of its luxury, places it in a segment with very high initial investment.

What Problems Does the 2026 Mercedes-Benz GLS-Class Have?
While Mercedes-Benz vehicles are generally known for their advanced engineering, the GLS-Class, like any complex luxury SUV, can experience certain issues. Historically, for preceding model years, some owners have reported minor electrical glitches, such as infotainment system freezes or connectivity problems with Apple CarPlay and Android Auto. Issues with the air suspension system, leading to uneven ride height or warning lights, have also been noted in some instances, though these are often repairable with specialized knowledge. Premature brake wear has been a concern for some performance-oriented trims. Regular and diligent maintenance is crucial to mitigate many potential long-term issues. Recalls, when they occur, are typically addressed by dealerships to fix specific component defects or software anomalies. For the upcoming 2026 model, it is crucial to monitor any official manufacturer recalls or service bulletins released by Mercedes-Benz. Early model years of any new generation often iron out initial kinks through software updates and minor hardware revisions. Therefore, relying on owner reviews and professional assessments from established automotive publications after the 2026 model has been on the market for some time will provide a clearer picture of any widespread or recurring problems specific to this iteration. The overall long-term reliability is expected to be strong, given Mercedes-Benz's commitment to quality, but proactive maintenance remains paramount.
How long will the 2026 Mercedes-Benz GLS-Class last?
Based on owner data for similar Mercedes-Benz GLS models, with consistent and high-quality maintenance, owners can realistically expect the 2026 GLS-Class to last for 150,000 to 200,000 miles or even more. Long-term durability is a strong suit for Mercedes-Benz vehicles, particularly in their higher-tier offerings like the GLS. However, potential weaknesses over time could emerge in the complex air suspension system, sophisticated electronic components, and high-performance engine parts, especially if maintenance schedules are neglected. Regular fluid changes, timely filter replacements, and proactive inspections are key to maximizing its lifespan and avoiding costly repairs down the line. Owners who prioritize meticulous upkeep can enjoy years of luxurious and reliable service from this flagship SUV.
What Technology & Safety Features are Included?
The 2026 Mercedes-Benz GLS-Class is a technological powerhouse, brimming with advanced features designed for convenience, safety, and entertainment. Standard technology typically includes the MBUX (Mercedes-Benz User Experience) infotainment system, featuring a large 12.3-inch dual screen display that integrates the instrument cluster and central touchscreen. This system offers intuitive voice control, gesture recognition, and seamless integration with Apple CarPlay and Android Auto. Wireless charging pads for front and rear passengers are usually standard, alongside multiple USB ports.
Optional technology upgrades often include a premium Burmester surround-sound audio system, augmented reality navigation that overlays directions onto a live camera feed, and enhanced rear-seat entertainment screens.
Driver-assistance and safety features are comprehensive. Standard equipment typically includes adaptive cruise control with steering assist, lane keeping assist, blind-spot monitoring, automatic emergency braking with pedestrian detection, and a 360-degree camera system. Optional packages often add features like Evasive Steering Assist, Active Lane Change Assist, and Traffic Sign Recognition.
While official 2026 model year crash-test ratings from the NHTSA and IIHS may not be immediately available, previous GLS models have consistently earned top safety scores, indicating a high level of occupant protection. Mercedes-Benz prioritizes robust safety structures and a full suite of airbags, further complemented by advanced electronic stability and traction control systems. The combination of cutting-edge technology and advanced safety systems makes the GLS-Class a leading contender in its segment for both passive and active safety.

How Does the 2026 Mercedes-Benz GLS-Class Compare to Other Sport Utility Vehicle?
The 2026 Mercedes-Benz GLS-Class competes in the highly contested full-size luxury SUV segment against formidable rivals such as the BMW X7, Audi Q8, Cadillac Escalade, and Lincoln Navigator.
Performance: The GLS-Class offers a sophisticated blend of power and refinement. Its inline-six and V8 engines provide potent acceleration, while the ride is exceptionally comfortable. The BMW X7 often matches or exceeds the GLS in outright performance, especially with its M variants, and offers a similarly dynamic driving experience. The Audi Q8, while a bit more performance-oriented and sportier in feel, is technically a coupe-SUV and may not offer the same passenger and cargo versatility as the GLS. The Cadillac Escalade and Lincoln Navigator provide robust V8 power and strong towing capabilities but often prioritize a more traditional, truck-like feel over the GLS's car-like handling and refined ride.
Features: Mercedes-Benz consistently leads in interior luxury and technology. The MBUX system in the GLS is among the best, with advanced graphics and intuitive operation. It generally rivals or surpasses the features found in the X7 and Q8. The Escalade and Navigator offer impressive technology and opulent interiors, but the GLS often feels a step ahead in terms of overall cohesiveness and premium material execution.
Reliability: Historically, Mercedes-Benz has a strong reputation for reliability, though luxury vehicles with complex systems can be prone to more expensive repairs. BMW and Audi also offer solid reliability, but owners often cite higher long-term maintenance costs across the board for German luxury brands. Cadillac and Lincoln have improved significantly, but German competitors often maintain a slight edge in perceived build quality and long-term durability perception.
Price: The GLS-Class is typically priced at the higher end of the segment, aligning closely with the BMW X7. The Audi Q8 might be slightly less expensive depending on configuration. The Cadillac Escalade and Lincoln Navigator often start at a lower price point for their base models but can quickly escalate with higher trims and options.
Alternatives: If supreme comfort, cutting-edge tech, and a prestigious badge are paramount, the GLS is an excellent choice. However, if a more engaging driving experience is desired without sacrificing luxury, the BMW X7 is a very strong contender and arguably its closest rival. For those seeking more traditional American luxury and brute force, the Cadillac Escalade or Lincoln Navigator are compelling options, often offering more outright space and towing prowess at a potentially lower entry price. The Audi Q8 is a good choice for those who prefer a sportier aesthetic and driving dynamics in a large SUV form factor.
