The Mercedes GLE W166 is actually the second phase of the third generation of Mercedes-Benz's luxury SUV. Initially launched in 2011 under the ML (W166) designation, it underwent a significant facelift in 2015, adopting the new GLE nomenclature. This model is positioned in the large premium SUV segment, offering a blend of luxury, comfort, on-road capabilities, and, for some versions, off-road performance. It is renowned for its spacious interior, quality materials, and high level of equipment. General reliability is good for a vehicle in this category, but like any complex premium SUV, it presents specific points of attention, particularly concerning electronic systems and sophisticated diesel engines.
The Mercedes ML/GLE W166 is an excellent premium SUV, offering undeniable comfort and luxury. Its reliability is generally good, but it is a complex vehicle whose maintenance must not be neglected. The diesel engines, particularly the V6 OM642 (GLE 350 d), are the most recommendable for their driving pleasure, performance, and relatively controlled consumption. However, be vigilant about the maintenance history of the AdBlue system and the oil cooler. The V6 gasoline versions are also good choices for those who drive less or prefer the smoothness of gasoline. The V8 and AMG versions are performance beasts, but their maintenance and consumption costs are very high. The air suspension (Airmatic) is a plus for comfort but a point to watch with age. A clear maintenance history and a thorough inspection before purchase are imperative. If these conditions are met, the GLE W166 remains a relevant choice on the used car market.
