Are Mercedes-Benz GLS models reliable?

Owners consistently give the GLS high marks for comfort, craftsmanship, and overall driving satisfaction, and the expert reviews echo that premium, well-finished character. The model’s strong owner ratings across the lineup point to a vehicle that many shoppers find rewarding to live with.

• Owners rate the Mercedes-Benz GLS between 4.5 and 5.0 out of 5 stars across all model years in the data.

For used buyers, long-term ownership risk is best managed by checking service history, because higher-mileage examples can bring more wear and more variable upkeep costs.

What should I look for when buying a used Mercedes-Benz GLS?

Across all model years, accident-free inventory is solid at 84.1% — always verify the vehicle history report.

Older model years carry meaningfully higher accident rates, so always verify the vehicle history report on pre-2020 models.

Key things to evaluate:

• Safety package: Nearly 40 safety and driver-assistance systems appear on the 2026 GLS’ standard equipment list, including Mercedes’ innovative Pre-Safe, Crosswind Assist, and Active Emergency Stop Assist technologies.
• Infotainment: Wireless Apple CarPlay and Android Auto and a navigation system with augmented reality enhancement are standard.
• Fuel efficiency: It’s EPA-rated at 21 mpg combined, but with the standard Dynamic Select system in the Comfort driving mode for most of the test-drive, we observed 19.4 mpg on our mountainous Southern California evaluation route.

Which Mercedes-Benz GLS trim should I buy?

The 2026 Mercedes-Benz GLS offers these trims:

• GLS 450: The best-value choice if you want the base GLS with the standard turbocharged 3.0-liter inline-six, mild-hybrid assist, nine-speed automatic transmission, standard 4Matic AWD, and Airmatic adaptive suspension.
• GLS 580: Step up for more power and a more performance-focused feel within the GLS lineup.
• AMG GLS 63: Choose this if you want the high-performance AMG version with the most aggressive capability in the range.
• Maybach GLS 600: Pick this for the most opulent GLS experience and the highest level of luxury.

What Mercedes-Benz GLS do most buyers choose?

The Mercedes-Benz GLS years with the most listings are 2025, 2024, and 2023.

Those higher-volume years tend to be popular because they give you more inventory to compare, which can make it easier to find the right color, mileage, and equipment mix. They also sit in the part of the lineup where newer features and broader availability often overlap.

What is the Mercedes-Benz GLS's resale value?

The table shows broad downward movement across the GLS lineup, which can work in your favor if you’re shopping used. Several years have double-digit declines, so you may find stronger value in recent-model inventory than you would expect from a luxury SUV. The smallest changes are still negative, which means prices are generally easing rather than rising.

The 2017, 2021, and 2023 model years have held their value best, with the smallest year-over-year price changes.

Is the Mercedes-Benz GLS safe?

• 2026: 7/10
• 2024: 10/10
• 2022: 6/10
• 2021: 9/10

Nearly 40 safety and driver-assistance systems appear on the 2026 GLS’ standard equipment list, including Mercedes’ innovative Pre-Safe, Crosswind Assist, and Active Emergency Stop Assist technologies.

For the safest used buy, the 2024 model posts the highest confirmed score of 10/10.

Should I buy a used Mercedes-Benz GLS now or wait for the next model?

The powertrain supplies 375 horsepower and 369 pound-feet of torque, and is coupled with a nine-speed automatic transmission and standard 4Matic all-wheel-drive (AWD), accelerating the GLS 450 0-60 mph in a manufacturer-estimated 5.8 seconds.

If you're buying used today, the 2025 model year offers the best mix of value and availability. If you want the latest tech and features, it may be worth waiting for 2028 inventory to mature.
