The 2022 Mercedes-Benz GLS is a full-size luxury SUV with three rows of seating, designed for families and drivers who want flagship comfort with serious power. It’s part of the third-generation GLS (introduced for 2020), which brought a larger cabin, updated tech, and modern turbocharged engines. In the market, it competes with premium rivals like the BMW X7 and Range Rover, offering a strong balance of refinement, towing capability, and advanced safety. The GLS is ideal for buyers who prioritize a quiet ride, high-end materials, and everyday practicality without giving up performance.

1) Three-row luxury space: Seating for up to seven (or available second-row captain’s chairs for six) with a spacious cargo area and power-folding seats on many builds. 2) Turbocharged engine lineup: Common 2022 GLS trims include the GLS 450 with a 3.0L turbo inline-6 with EQ Boost mild-hybrid assist, and the GLS 580 with a 4.0L twin-turbo V8 with EQ Boost; both are paired with a 9-speed automatic transmission. 3) Confident all-weather traction: 4MATIC all-wheel drive is widely available and commonly equipped, helping the GLS feel secure in rain and snow and improving towing stability. 4) Air suspension and ride comfort: Many GLS models feature AIRMATIC air suspension, delivering a smooth, adjustable ride height and a luxury-focused driving feel. 5) Tech and safety: A large dual-screen MBUX infotainment setup, available augmented navigation, advanced driver assistance features, and an upscale cabin experience make the GLS feel like a flagship.

Shoppers often search “2022 Mercedes-Benz GLS reliability” and “2022 Mercedes-Benz GLS common issues” because this SUV mixes advanced electronics with complex powertrains. Overall, many owners report a solid luxury experience when properly maintained, but a few problems show up repeatedly. 1) Suspension and air system faults: GLS models equipped with AIRMATIC can experience air leaks, sagging after sitting, compressor issues, or suspension warnings. Symptoms may appear anywhere from 20,000 to 60,000 miles depending on use and climate, and repairs can be expensive if components need replacement. 2) Infotainment and electrical glitches: Some owners report MBUX screen freezes, random reboots, camera or sensor errors, and intermittent driver-assist warnings. These often show up early in ownership and may be improved with software updates, but persistent issues can require dealer diagnosis and module resets. 3) 48-volt mild-hybrid (EQ Boost) system concerns: On some GLS 450/580 vehicles, owners have reported warning lights, battery/charging-related messages, or drivability changes tied to the 48V system. Not every vehicle is affected, but diagnosis can be more involved than a traditional 12V system. 4) Brake wear and noise complaints: The GLS is heavy, and some owners notice faster-than-expected brake pad wear, brake dust, or squeaking. Depending on driving style, pads may need attention in the 25,000 to 45,000-mile range, especially with lots of city driving.
