The fourth-generation Jeep Grand Cherokee (WK2) marks a major turning point for the model. Developed during the DaimlerChrysler alliance era, it shares its platform with the Mercedes-Benz M-Class (W166). This SUV combines exceptional off-road capabilities (Quadra-Trac and Quadra-Drive systems) with road handling and comfort worthy of the premium segment. It benefited from two notable facelifts (2014 with the introduction of the excellent 8-speed ZF automatic gearbox, and 2017). Overall reliability rating: A striking contrast. According to the ADAC and the TÜV Report, the overall assessment is below the category average. However, this rating is dragged down by temperamental electronics (Uconnect system), fragile air suspension, and a highly problematic diesel engine (EcoDiesel). Conversely,
The Jeep Grand Cherokee WK2 is a vehicle with two faces. If you opt for a petrol engine (the 3.6L V6 Pentastar being the most rational choice, or the 5.7L V8 for towing), you will get a mechanically very reliable SUV that is comfortable and formidable off-road. Favor a post-2014 model to benefit from the excellent 8-speed ZF automatic gearbox and a modernized interior. On the other hand, avoid the 3.0L EcoDiesel engine. The data from the ADAC, TÜV Report, and NHTSA are damning: the breakdowns are serious, recurrent, and extremely costly (injection pump, EGR, sensors). Furthermore, regardless of the engine, be prepared for potential electronic quirks (multimedia system) and, if possible, avoid the Quadra-Lift air suspension on high-mileage used models, as its replacement is ruinously expensive.
