The 2015 Jeep Grand Cherokee Summit stands out in the crowded midsize SUV segment. With premium features, strong performance, and a focus on luxury, the Summit trim aims to give drivers something special without sacrificing Jeep’s reputation for ruggedness.
If you’re considering a Grand Cherokee, the Summit edition from 2015 deserves a closer look.
Let’s explore what makes this SUV unique, where it shines, and where it could improve.
Design And Interior Quality
Jeep designed the 2015 Grand Cherokee Summit to impress from the outside in. The exterior styling is sophisticated, with chrome trim, unique wheels, and Summit-specific badging. LED daytime running lights and bi-xenon headlamps add a modern touch.
Step inside, and you find high-end leather, open-pore wood accents, and real metal trim. The seats are both heated and ventilated in the front, and rear passengers also get heated seats. The panoramic sunroof floods the cabin with light, making the interior feel even more spacious.
What’s notable for this price point is the attention to detail. The Nappa leather feels soft, and the dashboard layout is clean and intuitive.
However, tall adults may find rear headroom a bit tight due to the sloping roofline.
Performance And Driving Experience
The 2015 Summit comes standard with a 3.6-liter V6 engine (290 horsepower) paired to an eight-speed automatic transmission. Optional engines include a 5.7-liter V8 (360 horsepower) and a 3.0-liter EcoDiesel V6 (240 horsepower, 420 lb-ft torque).
Here’s how the engines compare:
| Engine | Horsepower | Towing Capacity | Fuel Economy (MPG city/highway) |
|---|---|---|---|
| 3.6L V6 | 290 | 6,200 lbs | 17/24 |
| 5.7L V8 | 360 | 7,200 lbs | 14/22 |
| 3.0L Diesel | 240 | 7,200 lbs | 22/30 |
The V6 offers enough power for daily driving, but the V8 is better for towing or spirited driving. The diesel stands out for its excellent fuel economy and strong torque, which is great for long trips or hauling.
On the road, the Summit is quiet and comfortable. The adaptive air suspension smooths out rough roads and can be raised for off-road situations. This system is especially helpful for drivers who want both luxury and some real off-road ability.
Technology And Features
Jeep packed the Summit with top-tier tech for 2015. The 8.4-inch Uconnect touchscreen is responsive and easy to use. Navigation, Bluetooth, HD radio, and a 19-speaker Harman Kardon audio system come standard. The sound quality is impressive, making music and podcasts enjoyable even at highway speeds.
Other standout features include:
- Adaptive cruise control
- Forward collision warning
- Blind spot monitoring
- Rear cross-traffic alert
- Parking sensors and backup camera
Remote start and a power liftgate add convenience. The digital gauge cluster can be customized to show trip info, navigation, or vehicle stats.
Some drivers feel the Uconnect system is occasionally slow to start up, but it’s one of the better infotainment setups from this era.
Comfort And Practicality
Space is generous for four adults, and the seats are supportive for long drives. The Summit’s cabin is one of the quietest in its class, thanks to extra sound-deadening materials and acoustic glass.
Cargo space is 36. 3 cubic feet behind the rear seats and 68.
3 cubic feet with them folded. This is enough for luggage, sports gear, or a big grocery haul.
Here’s how the 2015 Grand Cherokee Summit compares to a key rival:
| Model | Cargo (Seats Up) | Rear Legroom | Max Towing |
|---|---|---|---|
| Grand Cherokee Summit | 36.3 cu ft | 38.6 in | 7,200 lbs |
| Toyota 4Runner Limited | 47.2 cu ft | 32.9 in | 5,000 lbs |
While the Grand Cherokee’s cargo space isn’t class-leading, its towing capacity and comfort make it more versatile for some buyers.
Safety And Reliability
The 2015 Grand Cherokee Summit received good safety scores from the NHTSA (four out of five stars overall). It comes equipped with modern safety tech, such as lane departure warning and automatic emergency braking.
Some owners report minor electronic glitches, especially with the Uconnect system and air suspension. Keeping the software updated and regular maintenance can help avoid most problems.
On the reliability front, the V6 engine is the most trouble-free. The diesel requires proper care, especially regarding fuel quality and regular oil changes.
V8 models can be thirsty but are generally robust.
Ownership Costs
The Summit’s premium features come at a higher price compared to lower trims. Used prices in 2024 range from $18,000 to $28,000 depending on mileage and condition.
Insurance costs are average for the segment. Maintenance can be more expensive than some rivals, especially for the air suspension and electronics.
However, the Summit holds its value better than some other luxury SUVs in its age range.
Fuel costs vary by engine choice:
- V6: Most balanced for daily use
- V8: Higher fuel use, better for towing
- Diesel: Best efficiency, higher maintenance
Two non-obvious insights: First, the air suspension requires periodic service and can be costly if neglected. Second, the diesel engine is great for long-distance drivers but may not be the best choice for short, frequent trips due to emission system needs.
Who Should Consider The 2015 Grand Cherokee Summit?
This SUV is ideal for buyers who want a luxury experience in a vehicle that can handle snow, rough roads, and towing. It’s also a smart pick for those who value a quiet ride, high-quality sound, and advanced safety tech.
However, if you need third-row seating or maximum cargo space, you might want to look at other options.
The 2015 Summit proves that a rugged SUV can also deliver comfort and sophistication. If you want a true all-rounder with a touch of class, it’s worth a test drive.
