The 2022 Jeep Grand Cherokee L Summit represents a pivotal moment in the evolution of the American SUV, blending three-row practicality with high-end luxury that rivals European competitors. As a flagship trim of the WL-generation, the Summit provides a sophisticated balance of off-road capability, advanced safety technology, and premium interior craftsmanship.
In the current 2026 automotive landscape, the 2022 Grand Cherokee L Summit has transitioned into a highly sought-after pre-owned vehicle. It remains a benchmark for families who require significant towing capacity and off-road prowess without sacrificing the comforts of a premium cabin. This guide examines the technical specifications, long-term reliability, and market value of this specific model year to help buyers and owners understand its unique position in the Jeep lineup.
The Significance of the 2022 "L" Designation
The 2022 model year was the first full production year for the "L" variant of the redesigned Grand Cherokee. While the name "Grand Cherokee" has existed for decades, the "L" signifies the extended wheelbase version, which introduced a permanent third row of seating. This was a direct response to the growing demand for larger family haulers that didn't require stepping up to the much larger Wagoneer or Grand Wagoneer.
The 2022 Jeep Grand Cherokee L Summit sits on the WL platform, which utilized significantly more high-strength steel than previous generations, resulting in a stiffer chassis and improved handling. For the Summit trim, this foundation is augmented by the Quadra-Lift Air Suspension system, which allows the vehicle to raise for ground clearance or lower for aerodynamic efficiency and ease of entry.
Performance and Powertrain Options
When the 2022 Grand Cherokee L Summit was released, it offered two primary engine choices. Understanding these options is critical for anyone evaluating the vehicle’s performance capabilities in 2026.
3.6L Pentastar V6
The standard engine for the Summit trim is the 3.6L Pentastar V6. This engine is a staple of the Stellantis (formerly FCA) lineup, known for its reliability and smooth power delivery. It produces 290 horsepower and 257 lb-ft of torque. While it provides adequate power for daily commuting and highway merging, it is often seen as the "efficient" choice rather than the "performance" choice. It is paired with a TorqueFlite eight-speed automatic transmission.
5.7L HEMI V8
For those requiring more muscle, the 2022 Summit was available with the legendary 5.7L HEMI V8. Delivering 357 horsepower and 390 lb-ft of torque, this engine transforms the Grand Cherokee L into a potent towing machine. By 2026, these V8 models have become increasingly rare as manufacturers move toward turbocharged four-cylinder and hybrid powertrains, making the 2022 V8 Summit a "future classic" for enthusiasts of traditional American power.

The Summit Trim: Defining Modern Luxury
The Summit trim is positioned just below the "Summit Reserve" package, but it includes almost every luxury feature available in the Jeep portfolio. The interior of the 2022 Summit was a radical departure from previous Jeep designs, aiming squarely at brands like BMW, Mercedes-Benz, and Lexus.
Interior Craftsmanship
The cabin is defined by Palermo leather-trimmed seats with quilted bolsters. In the Summit trim, the front seats are not just heated and ventilated; they also feature 16-way power adjustments with a massage function. The use of genuine Absolute Oak wood trim and Liquid Chrome accents provides a tactile quality that was previously absent in the Grand Cherokee line.
Quad-Zone Climate Control
Unlike many three-row SUVs that offer only tri-zone control, the Grand Cherokee L Summit features a sophisticated quad-zone system. This allows the driver, front passenger, and the occupants of the second-row captain's chairs to set individual temperatures, ensuring comfort across all rows during long trips.
McIntosh Premium Audio
One of the standout features of the 2022 Summit is the availability of the McIntosh MX950 Entertainment System. This system features 19 speakers, a 17-channel 950-watt amplifier, and a 10-inch subwoofer. For audiophiles, the signature McIntosh blue "analog" meters displayed on the infotainment screen are a nostalgic and high-end touch that distinguishes the Jeep from its peers.
Advanced Technology and Connectivity
In 2022, Jeep introduced the Uconnect 5 infotainment system, which remains highly functional and competitive even in 2026. This system is centered around a 10.1-inch flush-mounted touchscreen that supports wireless Apple CarPlay and Android Auto.
Safety and Driver Assistance
The 2022 Grand Cherokee L Summit was equipped with a robust suite of safety technologies as standard. Key features include:
- Active Driving Assist: A Level 2 automated driving system that uses lane centering and adaptive cruise control to assist on highways.
- 360-degree Surround View Camera: Essential for maneuvering a vehicle of this size in tight parking spaces.
- Intersection Collision Assist: Detects vehicles approaching from either side at an intersection and can apply emergency braking.
- Night Vision Camera: (Optional) Uses thermographic technology to detect pedestrians or animals in the dark beyond the reach of the headlights.
For official safety ratings and recall information regarding the 2022 model, owners and buyers should consult the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS).
Off-Road Capability: The Jeep DNA
Despite its luxury trappings, the Summit trim does not abandon Jeep’s off-road heritage. It comes standard with the Selec-Terrain Traction Management System, which allows the driver to toggle between Auto, Sport, Rock, Snow, and Mud/Sand modes.
The Summit trim typically utilizes the Quadra-Drive II 4WD system (standard on V8, often available on V6), which includes a rear Electronic Limited-Slip Differential (eLSD). This system can move 100% of available torque to a single rear wheel if it detects slip, providing class-leading traction in low-grip scenarios. The official Jeep website provides further details on the mechanical nuances of these 4WD systems for those interested in technical depth.
Maintenance and Long-Term Reliability in 2026
As the 2022 Grand Cherokee L Summit reaches four years of age, certain maintenance patterns and common issues have emerged. Prospective buyers in 2026 should be aware of the following:
Software and Electronics
The Uconnect 5 system in early 2022 models occasionally experienced glitches, such as screen freezing or wireless connectivity drops. Most of these issues were resolved via Over-the-Air (OTA) updates. Ensuring that a used 2022 vehicle has the latest firmware is a critical step during inspection.
Air Suspension Care
The Quadra-Lift air suspension is a complex system involving air bags, compressors, and sensors. While it provides an exceptional ride, it requires periodic inspection. In colder climates, moisture in the lines can sometimes lead to valve issues, though this is less common in the newer WL platform than in the older WK2 generation.
Engine Longevity
The Pentastar V6 is generally considered a 200,000-mile engine with proper maintenance. The 5.7L HEMI is also robust, though it requires strict adherence to oil change intervals to prevent "HEMI tick" (manifold or lifter issues). Using the manufacturer-recommended oil weight is non-negotiable for these engines.
2022 Summit vs. Summit Reserve: Key Differences
It is common for buyers to confuse the Summit with the Summit Reserve. While the 2022 Summit is exceptionally well-equipped, the Summit Reserve was an optional package that pushed the luxury boundaries even further.
- Wheels: The Summit features 20-inch polished aluminum wheels, while the Summit Reserve upgrades to 21-inch machined face wheels.
- Leather: Both use Palermo leather, but the Reserve adds it to the door wraps and the top of the instrument panel.
- Audio: The McIntosh system is standard on the Reserve but was sometimes an optional upgrade on the base Summit.
- Front Passenger Screen: The Reserve often includes an interactive display for the front passenger, allowing them to manage navigation or watch media independently.
FAQs About the 2022 Jeep Grand Cherokee L Summit
Does the 2022 Grand Cherokee L Summit have a panoramic sunroof?
Yes, the CommandView Dual-Pane Panoramic Sunroof is standard on the Summit trim. It features a power sunshade and a front pane that opens fully, providing an airy feel to all three rows of the cabin.
What is the difference between Quadra-Trac II and Quadra-Drive II?
Quadra-Trac II is a two-speed transfer case that can detect tire slip and route power to the axle with the most traction. Quadra-Drive II adds a rear Electronic Limited-Slip Differential (eLSD), which can distribute power between the individual rear wheels, significantly enhancing off-road and foul-weather capability.
How much cargo space is available behind the third row?
The 2022 Grand Cherokee L offers approximately 17.2 cubic feet of cargo space behind the third row. With the third row folded flat, this expands to 46.9 cubic feet, and with both the second and third rows folded, it reaches a maximum of 84.6 cubic feet.
Is the 2022 model year reliable?
Generally, yes. However, as the first full year of a new generation (WL), early production units sometimes faced minor assembly-quality issues or electronic bugs. Most of these have been addressed through factory recalls or TSBs (Technical Service Bulletins). Always check the VIN on the NHTSA website for open recalls.
Can the 2022 Grand Cherokee L Summit be flat-towed behind an RV?
Yes, provided it is equipped with a 4WD system that has a 4-Low range (like Quadra-Trac II or Quadra-Drive II), the transfer case can be shifted into neutral, allowing for flat towing (dinghy towing) behind a motorhome.
Final Recommendations for Buyers
In 2026, the 2022 Jeep Grand Cherokee L Summit stands as a high-value proposition for those who want a "near-luxury" experience without the maintenance costs of a German SUV. When shopping for this vehicle, prioritize units that have a documented service history at a Jeep dealership, as this ensures that all critical Uconnect software updates and recalls have been performed.
If you plan on towing heavy trailers or boats, the 5.7L HEMI V8 is the superior choice, despite its higher fuel consumption. However, for most families, the 3.6L V6 provides a better balance of daily drivability and lower insurance premiums. Regardless of the engine, the Summit’s interior remains one of the best in its class, offering a level of serenity and material quality that remains impressive years after its initial launch.
