Mercedes' seven-passenger SUV, the GLS, was recently freshened, gaining revised interior and exterior styling, a nine-speed automatic, an upgraded air suspension, and the addition of the current, and more complex, Mercedes-Benz infotainment system. Our last tested version was plush and quiet, with supportive seats and a third-row seat that was roomy enough for adults.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.
