The 3rd generation Jeep Grand Cherokee (code name WK in North America, WH in Europe) marks a major turning point for the model. Developed under the DaimlerChrysler era, it abandons the solid front axle in favor of independent suspension, significantly improving its road handling while maintaining excellent off-road capabilities thanks to the Quadra-Trac II and Quadra-Drive II systems. In Europe, it was primarily sold with the Mercedes-Benz sourced diesel V6 (OM642). A facelift occurred in late 2007 (2008 model year), bringing a much higher quality interior finish (the hard plastics of the 2005-2007 models being highly criticized), optional xenon headlights, and an overhaul of the 4.7L V8. It is a robust 4x4, but its electronics and certain engine peripherals require rigorous monitoring.
The Jeep Grand Cherokee WK (2005-2010) is a 4x4 with character, offering an excellent compromise between on-road and off-road. The most rational choice in Europe remains the 3.0 CRD, provided you buy an example whose known ailments (turbo seal, oil cooler, Swirl actuator) have already been addressed with invoices. V8 enthusiasts will turn to the 5.7 Hemi, which is very robust if maintained with the correct oil. It is imperative to favor a facelifted model (2008-2010) to benefit from a worthy interior and slightly more reliable electronics. Avoid examples without a maintenance history for the axles and transfer case.
