I. A Legacy of Excellence: Understanding the Grand Cherokee Lineage

The Jeep Grand Cherokee has always held a significant place in the SUV landscape, pioneering the concept of the "luxury SUV" since its dramatic debut in 1992. The WK2 generation, introduced for the 2011 model year, marked a significant leap forward in terms of refinement, on-road dynamics, and technological sophistication, largely benefiting from its shared platform with the Mercedes-Benz ML-Class during the DaimlerChrysler era.

The 2015 model year benefited from updates introduced in 2014, which brought a refreshed exterior design, an updated Uconnect infotainment system, and the new 8-speed automatic transmission across the lineup. Within this already impressive generation, the Summit trim was conceived as the ultimate expression of luxury and capability. While other trims like Laredo, Limited, and Overland offered varying degrees of comfort and features, the Summit ascended beyond them by incorporating virtually every available premium option as standard, leaving little to be desired. It wasn’t just a vehicle with more features; it was a curated experience designed to compete directly with high-end offerings from established luxury brands, all while retaining the rugged soul of a Jeep. This strategic positioning made the Summit a compelling choice for those seeking both opulence and genuine off-road credentials.

II. Unpacking the Summit’s Premium Features and Design

The 2015 Grand Cherokee Summit distinguishes itself through an exquisite blend of design elements and an extensive list of premium features that elevate it beyond its siblings. Every detail, from the exterior lines to the interior stitching, was meticulously crafted to convey a sense of exclusivity and refinement.

Exterior Aesthetics

Visually, the Summit presents an imposing yet elegant stance. It features a unique, more refined chrome grille with mesh inserts, complemented by distinct lower fascia and fog light bezels. Standard 20-inch polished aluminum wheels with satin clear coat further enhance its premium look, setting it apart from other trims. Full LED daytime running lights and taillights contribute to a modern appearance while improving visibility. The overall design language is muscular and purposeful, yet sophisticated enough to feel at home in any upscale environment.

Interior Opulence

Stepping inside the 2015 Summit reveals its true character as a luxury vehicle. The cabin is an exercise in premium craftsmanship, adorned with high-quality materials and thoughtful touches. Key interior features include:

• Natura Plus Leather Trim: Supple and soft, this premium leather upholstery covers the seats, door panels, and dashboard, often featuring unique stitching patterns.
• Open-Pore Wood Trim: Genuine open-pore wood accents adorn the dashboard, door panels, and steering wheel, offering a tactile and visually appealing contrast to the leather and chrome.



• Suede-like Headliner: A luxurious suede-like material lines the headliner, adding to the cabin’s plush ambiance and contributing to improved acoustics.
• Heated and Ventilated Front Seats: Ensuring comfort in all climates, the front seats offer both heating and ventilation.
• Heated Rear Seats: Passengers in the second row also benefit from heated outboard seats.
• Heated Steering Wheel: A standard feature that provides comfort during colder weather.
• Dual-Pane Panoramic Sunroof: This expansive glass roof stretches over both rows, bathing the cabin in natural light and offering an airy feel.



• Premium Audio System: The Harman Kardon 19-speaker audio system with a 825-watt amplifier and subwoofer delivers an immersive, concert-like sound experience.
• Uconnect 8.4-inch Touchscreen: The heart of the infotainment system, providing access to navigation, climate control, media, and vehicle settings.
• Active Noise Cancellation: Helps to create an exceptionally quiet cabin, further enhancing the luxury experience.

Every element within the Summit’s interior is designed to cocoon occupants in comfort and provide an intuitive, high-tech experience, making long journeys as enjoyable as short commutes.

III. Power and Performance: Beneath the Hood

The 2015 Grand Cherokee Summit offers a choice of two robust engines, both paired with an advanced 8-speed automatic transmission, ensuring a blend of power, efficiency, and refined performance.

Standard Engine: 3.6L Pentastar V6

The standard powerplant for the Summit is the award-winning 3.6-liter Pentastar V6 engine. This engine produces a healthy 290 horsepower and 260 lb-ft of torque. Known for its smooth operation and strong low-end torque, the Pentastar V6 provides ample power for daily driving, highway cruising, and light towing. It also offers respectable fuel economy for an SUV of its size, making it a balanced choice for many owners.

Optional Engine: 5.7L HEMI V8

For those desiring more robust performance and greater towing capability, the Summit offers the legendary 5.7-liter HEMI V8 engine. This powerhouse delivers 360 horsepower and a substantial 390 lb-ft of torque. The HEMI provides exhilarating acceleration and makes towing heavier loads (up to 7,400 lbs when properly equipped) feel effortless. Its Multi-Displacement System (MDS) can deactivate cylinders under light load conditions to improve fuel efficiency, though it naturally consumes more fuel than the V6.

Transmission and Drivetrain

Both engines are mated to a smooth and responsive ZF-sourced 8-speed automatic transmission. This advanced transmission optimizes power delivery, enhances fuel efficiency, and provides seamless gear changes, contributing significantly to the Summit’s refined driving experience.

Crucially, the 2015 Grand Cherokee Summit comes standard with Jeep’s most advanced 4×4 system, Quadra-Drive II. This system includes a two-speed transfer case and an electronic limited-slip differential (ELSD) at the rear axle, which can send nearly 100% of available torque to a single wheel if needed for maximum traction. This, combined with the Quadra-Lift Air Suspension, allows for adjustable ride height, offering:

• Normal Ride Height (NRH): Standard everyday driving.
• Off-Road I: Lifts the vehicle by 1.3 inches for added clearance.
• Off-Road II: Lifts the vehicle by an additional 1.3 inches (total 2.6 inches over NRH) for extreme off-road conditions.
• Park Mode: Lowers the vehicle by 1.6 inches for easier entry/exit and cargo loading.
• Aero Mode: Automatically lowers the vehicle at highway speeds for improved aerodynamics and fuel efficiency.

The Select-Terrain Traction Management System further enhances capability, offering five modes (Auto, Snow, Sand, Mud, Rock) that optimize powertrain, brakes, and suspension settings for specific conditions. This combination of powerful engines, sophisticated transmission, and advanced 4×4 systems ensures the Summit is equally capable on paved roads as it is tackling challenging trails.

IV. Technology and Safety: A Modern Command Center

The 2015 Grand Cherokee Summit was equipped with a suite of advanced technology and safety features that were cutting-edge for its time, providing both convenience and peace of mind.

Infotainment and Connectivity

The centerpiece of the Summit’s technological offerings is the Uconnect 8.4-inch touchscreen infotainment system. This intuitive system includes:

• Navigation: Garmin-based navigation system with detailed maps and voice guidance.
• Bluetooth Connectivity: For hands-free phone calls and audio streaming.
• Voice Commands: Control various functions without taking hands off the wheel.
• SiriusXM Satellite Radio: With a subscription, offering a wide array of entertainment options.

• Mobile Apps: Access to a limited selection of Uconnect apps (e.g., Pandora, Yelp) through a compatible smartphone.

While it predates Apple CarPlay and Android Auto integration (which became standard in later model years), the 2015 Uconnect system was praised for its user-friendly interface and responsiveness.

Driver-Assistance Systems

The Summit trim significantly boosted safety with a comprehensive array of advanced driver-assistance systems (ADAS), often packaged as the "Advanced Technology Group" but standard on the Summit:

• Adaptive Cruise Control with Stop and Go: Maintains a set distance from the vehicle ahead, capable of bringing the vehicle to a complete stop and resuming.
• Forward Collision Warning with Crash Mitigation: Alerts the driver to potential front-end collisions and can apply the brakes automatically if necessary.
• Blind Spot Monitoring with Rear Cross-Path Detection: Warns the driver of vehicles in their blind spots and when backing out of parking spaces.
• Parallel and Perpendicular Park Assist: Assists the driver in maneuvering into parking spots.
• Front and Rear ParkSense Park Assist System: Provides audible and visual warnings when approaching obstacles during parking maneuvers.

Passive Safety Features

Beyond these active systems, the 2015 Summit includes a full complement of passive safety features, such as multiple airbags (front, side-curtain, front-seat-mounted side, driver knee-bolster), electronic stability control (ESC), traction control, anti-lock brakes (ABS), and a rearview camera. These features work in concert to protect occupants and help prevent accidents.

V. Ownership Experience: What to Consider for a Used 2015 Summit

Purchasing a used 2015 Jeep Grand Cherokee Summit can be an excellent value proposition, offering luxury and capability at a significantly reduced price compared to new. However, like any used vehicle, there are specific considerations to ensure a positive ownership experience.

Maintenance and Common Considerations

Regular and diligent maintenance is paramount for the longevity of any premium vehicle, and the Summit is no exception. Key areas to focus on include:

• Air Suspension (Quadra-Lift): While incredibly versatile, air suspension systems can be complex. Listen for compressor noises, check for leaks, and ensure the system raises and lowers the vehicle smoothly and evenly. Components like air springs, compressors, and solenoids can eventually require replacement.
