Jeep Grand Cherokee (WK2): A Comprehensive Buyer's Guide

The Jeep Grand Cherokee (WK2) represents the fourth generation of Jeep's highly successful mid-size SUV. Launched in 2011, it marked a significant step up in refinement, technology, and capability compared to its predecessor, the WK. Building upon Jeep's legacy of off-road prowess, the WK2 aimed to blend luxury, performance, and ruggedness into a single package. This guide will delve into the WK2, covering its history, generations, reliability, driving experience, and providing essential buying advice for potential owners.

Generations and Key Changes

WK2 (2011-2022): The Fourth Generation

2011-2013: Pre-Facelift
The initial WK2 models boasted a completely redesigned chassis, independent front and rear suspension, and a significantly upgraded interior. Engine options included the 3.6L Pentastar V6 and the 5.7L Hemi V8. A Mercedes-Benz-derived transmission improved shift quality and efficiency. The Selec-Terrain system offered various drive modes for different terrains.

2014-2016: Mid-Cycle Refresh
A substantial refresh brought updated exterior styling, including revised headlights, grille, and taillights. The interior received enhancements to the dashboard, center console, and infotainment system. An 8-speed automatic transmission replaced the previous 5-speed and 6-speed units on most models, further improving fuel economy and performance. A new EcoDiesel V6 engine was introduced, offering excellent torque and fuel efficiency.

2017-2022: Continued Refinements & New Trims
Minor styling tweaks continued, and Jeep focused on expanding the trim level offerings. The Trailhawk trim was introduced, providing even greater off-road capability. The high-performance Trackhawk model, equipped with a supercharged 6.2L Hellcat V8, joined the lineup in 2018. Infotainment systems received upgrades, including Apple CarPlay and Android Auto compatibility.

Reliability & Common Issues

The Jeep Grand Cherokee WK2, while generally reliable, has experienced some common issues. Understanding these potential problems can help you make an informed purchasing decision and plan for potential maintenance.

Engine

3.6L Pentastar V6: Generally reliable, but prone to rocker arm issues (especially in earlier years) which can cause a ticking noise and eventual engine damage. Also, oil cooler leaks are common. Check for oil leaks around the oil filter housing.

5.7L Hemi V8: Known for its robust performance, but can suffer from "Hemi Tick" (a noisy valve lifter) and exhaust manifold bolts that break or corrode, leading to exhaust leaks. Also, cylinder deactivation (MDS) can sometimes lead to issues.

3.0L EcoDiesel V6: This engine has been plagued with issues, including turbocharger failures, EGR cooler failures, and excessive oil consumption. The diesel emissions system (DEF) can also be problematic. Extensive recalls have been issued for this engine. This engine may require expensive repairs and should be approached with caution.

6.2L Supercharged V8 (Trackhawk): While powerful, this engine requires meticulous maintenance and is susceptible to heat soak if pushed hard for extended periods. Ensure regular oil changes and consider upgrades to cooling systems if planning to track the vehicle.

Transmission

8-Speed Automatic (845RE/8HP45/8HP70): Generally reliable, but can experience rough shifting, especially in early model years. Ensure regular transmission fluid changes. Some owners have reported valve body issues.

Suspension & Drivetrain

Air Suspension (Quadra-Lift): While offering excellent ride quality and adjustable ride height, the air suspension system can be prone to leaks in the air springs or failure of the air compressor. Repairs can be costly. Listen for the compressor running frequently or excessively.

Transfer Case (Quadra-Trac/Quadra-Drive): Ensure proper function of the 4x4 system. Check for unusual noises or vibrations during engagement and disengagement. Regular fluid changes are crucial.

Electronic Limited-Slip Differential (ELSD): The ELSD (available on some models) requires regular maintenance and can be expensive to repair if neglected.

Electrical & Electronics

Uconnect Infotainment System: Early versions of Uconnect could be buggy. Ensure the software is up to date. Some owners have reported issues with touchscreen responsiveness and connectivity.

Power Liftgate: The power liftgate can sometimes experience issues with the latch or motor.

Driving Experience

The Jeep Grand Cherokee WK2 offers a versatile driving experience, balancing comfort, performance, and off-road capability.

Pros:

Comfortable Ride: The independent suspension provides a smooth and comfortable ride on paved roads.

Off-Road Capability: The Selec-Terrain system and available four-wheel-drive systems (Quadra-Trac I, Quadra-Trac II, Quadra-Drive II) make the Grand Cherokee highly capable off-road.

Engine Options: A wide range of engine options caters to different needs, from the fuel-efficient V6 to the potent V8s.

Refined Interior: The interior is well-appointed with high-quality materials and modern technology.

Towing Capacity: Offers competitive towing capacity for its class.

Cons:

Fuel Economy: Fuel economy, particularly with the V8 engines, can be poor.

Reliability Concerns: Some models and engine options have known reliability issues (as detailed above).

Air Suspension Complexity: The air suspension system, while comfortable, can be expensive to maintain.

Overall Size: Can feel large and cumbersome in tight city environments.

Buying Advice

Here's some practical advice to help you find the best Jeep Grand Cherokee WK2 for your needs:

Years to Consider:

2014-2016: These years represent the sweet spot, benefiting from the mid-cycle refresh, the 8-speed transmission, and improved infotainment. Avoid the EcoDiesel unless you are very mechanically inclined and aware of the potential issues.

2017-2020: Offer further refinements and newer technology, with fewer reported issues compared to earlier models.

Years to Potentially Avoid (or Exercise Caution):

Early 2011-2013 Models: May have more issues with the Pentastar V6 rocker arms, earlier transmissions, and less refined infotainment.

Models with the 3.0L EcoDiesel: Proceed with extreme caution. Thoroughly research the specific vehicle's maintenance history and check for any outstanding recalls. Budget for potential repairs.

What to Look For:

Maintenance Records: Look for a vehicle with a complete and well-documented maintenance history.

Pre-Purchase Inspection: Have a qualified mechanic perform a thorough pre-purchase inspection, paying particular attention to the engine, transmission, suspension, and 4x4 system.

Test Drive: Test drive the vehicle thoroughly, paying attention to engine performance, transmission shifting, and any unusual noises or vibrations.

Check for Recalls: Verify that all applicable recalls have been performed.

Air Suspension Check: If the vehicle is equipped with air suspension, carefully inspect the air springs and listen for any leaks or excessive compressor noise.

Uconnect Functionality: Test all features of the Uconnect infotainment system to ensure they are functioning properly.

Trim Levels to Consider:

Limited: Offers a good balance of features and value.

Overland: Provides a more luxurious experience with upgraded interior features.

Trailhawk: If off-roading is a priority, the Trailhawk is the best choice.
