About the 2026 Mercedes-Benz GLS
With an overall Carivo score of 7.2/10, the 2026 Mercedes-Benz GLS earns a Good rating among the suvs we've scored. Its strongest dimension is Technology at 8.5/10, while Reliability at 6.3/10 is where it trails the competition most noticeably. It's a capable but unexceptional suv — stronger alternatives exist if you're willing to shop the segment carefully.
Reliability and safety are the two dimensions that matter most for long-term ownership costs. We rate reliability at 6.3/10 — below the segment average in our scoring. Budget for potentially higher maintenance costs and check the recall record below before buying. On safety it earns 8.4/10: respectable, if not class-leading — several competitors bundle more driver-assist tech as standard. Check your trim's official ratings at nhtsa.gov.
Performance lands mid-pack at 7.1/10: enough power and composure for everyday needs, without the dynamics that distinguish the segment's driver-focused options. Technology scores 8.5/10 — one of the stronger tech packages in the segment. Expect a responsive infotainment system, broad smartphone integration, and a solid suite of driver-assistance features.
Priced from $85,232–$104,626, 21 MPG, seating 7, the Mercedes-Benz GLS sits in the luxury tier of the suv market. The value score of 6.4/10 is a red flag — comparable alternatives offer meaningfully more for the same outlay. Shop the segment before deciding. As the current model year, it benefits from the latest updates and full manufacturer warranty coverage.
Bottom line: There's a case for the 2026 Mercedes-Benz GLS, but it needs the right buyer. Its value and reliability scores trail the class, and several higher-rated rivals sell for similar money — comparison-shop before committing.
