20122019 · W166 · suv

Third-gen mid-size SUV. Launched as the ML in 2012; renamed GLE for 2016 model year as Mercedes consolidated naming. M276 V6 (ML350/GLE350), M278 biturbo V8 (GLE550), M157/M177 biturbo V8 in AMG. OM642 V6 BlueTEC diesel discontinued mid-cycle (Dieselgate fallout for OM642). Coupe variant (GLE Coupe, C292) shares the architecture.

Watch out: OM642 diesel cars: emissions-system software updates and SCR / DPF issues after Dieselgate-era recalls. M278 V8 timing chain guides. Airmatic compressors fail on highest-mileage examples. GLE Coupe (C292) carries the same patterns.

Full clubhouse — owner Garage Lineage, common problems, year-by-year notes, and product picks — is on the build list.
