- Summit – Top luxury trim with premium leather, adaptive cruise control, and upgraded sound system.
- SRT – 6.4L V8, performance-tuned suspension, Brembo brakes, and sporty interior.
- Trackhawk – Supercharged 6.2L V8 with 707 hp, high-speed capability, and race-derived features.
Each trim also offers optional packages like the Luxury Group and Safety & Security Group, so you can further tailor the SUV to your preferences.
Performance: Engine, Transmission, and Driving Dynamics
Engine Options and Power Outputs
Jeep offers four distinct powertrains for the 2021 Grand Cherokee. The 3.6L V6 (293 hp, 260 lb-ft) is the standard engine and provides adequate acceleration for daily driving. Step up to the 5.7L V8 (357 hp, 390 lb-ft) for stronger towing capacity—up to 6,200 pounds on V8 models. The 6.4L V8 in the SRT (470 hp, 470 lb-ft) and the supercharged 6.2L V8 in the Trackhawk (707 hp, 645 lb-ft) are for enthusiasts seeking extreme performance.
All engines pair with an 8-speed automatic transmission. Shift quality is smooth and responsive, though the V6 can feel somewhat strained during hard acceleration on steep grades. The V8s, especially the Trackhawk, deliver neck-snapping thrust. Fuel economy varies widely: the V6 achieves an EPA-estimated 19 city / 26 highway mpg; the 5.7L V8 drops to 14 city / 22 highway; and the Trackhawk barely reaches 11 city / 17 highway on premium fuel.
Handling and Ride Quality
The Grand Cherokee’s unibody construction (rather than a body-on-frame) gives it car-like handling compared to older SUVs. Steering is well-weighted, and the independent front and rear suspension absorb bumps capably. On non-performance trims, body roll is present but controlled. Models equipped with Quadra-Lift air suspension offer up to 6.4 inches of additional ground clearance and automatically adjust damping to improve ride comfort on rough roads.
Braking is strong across the lineup, with the SRT and Trackhawk using massive 15.4-inch front rotors with six-piston calipers for fade-free stops even during repeated high-speed braking.
Towing Capacity
Properly equipped, the 2021 Grand Cherokee can tow up to 7,200 pounds with the 5.7L V8 and the optional Trailer Tow Package. The V6 tows up to 6,200 pounds, while the performance SRT models are rated at 5,700 pounds. This makes the Grand Cherokee competitive with the Ford Explorer (up to 5,600 lbs) but slightly less than the Chevrolet Traverse (up to 7,500 lbs).
Reliability: Owner Reports and Common Issues
Consumer Reports and J.D. Power Ratings
The 2021 Jeep Grand Cherokee earns a predicted reliability rating of 3 out of 5 from J.D. Power, which is about average for the segment. Consumer Reports gives it a similarly middling score, citing potential electrical issues and transmission rougheness in some long-term tests. However, many owners report high satisfaction with the powertrain's durability, especially on Trailhawk and Limited trims.
Common complaints include Uconnect system lag, minor rattles in the interior trim, and premature brake wear on heavier models. The V8 engines are generally robust, but the Trackhawk’s supercharged engine requires strict adherence to maintenance schedules to avoid expensive repairs.
Warranty and Maintenance Costs
Jeep covers the 2021 Grand Cherokee with a 3-year/36,000-mile basic warranty and a 5-year/60,000-mile powertrain warranty. All models include 5-year/100,000-mile roadside assistance. These terms are standard for the industry but fall short of Hyundai and Kia’s longer coverage. Annual maintenance costs average around $650 for the V6 and roughly $800 for the V8, according to RepairPal—slightly above the midsize SUV average.
Reliability in Off-Road Conditions
The Grand Cherokee, especially the Trailhawk, is built for tough terrain. Its sealed electrical connectors, heavy-duty cooling system, and reinforced underbody contribute to longevity in dusty, muddy, or rocky environments. The Quadra-Drive II system with electronic rear limited-slip differential is exceptionally durable, though the air suspension components may require attention after 100,000 miles.
Safety and Driver Assistance Technology
The National Highway Traffic Safety Administration (NHTSA) gave the 2021 Grand Cherokee an overall safety rating of 4 out of 5 stars. The Insurance Institute for Highway Safety (IIHS) awarded it a “Good” rating in most crash tests but noted marginal performance in the passenger-side small overlap front test.
Available safety features include:
- Forward-collision warning with active braking
- Blind-spot monitoring and rear cross-traffic alert
- Lane-keeping assist
- Adaptive cruise control (full-speed)
- ParkSense rear park assist with automatic braking
- Surround-view camera system
These features are standard on higher trims like Overland and Summit, but are optional on Laredo and Limited. Buyers seeking top safety scores should prioritize models with the Advanced Safety Group package.
Interior Comfort, Cargo, and Technology
Seating and Materials
The cabin of the 2021 Grand Cherokee is generally well-trimmed, with soft-touch materials on the dashboard and door panels even in base trims. Leather upholstery is available from the Limited up, and Summit models feature Nappa leather with contrast stitching. Front seats are supportive and offer up to 12-way power adjustment. Rear seats provide decent legroom for adults, but the seatback angle is fixed, which may be less comfortable on very long trips. The SUV seats five occupants only; no third row is offered.
Cargo Space
Cargo volume measures 36.3 cubic feet behind the rear seats and 68.3 cubic feet with the seats folded. That’s comparable to the Honda Passport but less than the Chevrolet Blazer (reach 64.6 cu ft). The rear hatch opens wide, and the load floor is flat when seats are down. A power liftgate is standard on most trims, and the Summit adds hands-free operation.
Infotainment and Connectivity
The Uconnect 5 system (new for 2021 on many trims) is one of the best in the industry. The 8.4-inch screen is standard, and a 10.1-inch unit is available on higher trims. Apple CarPlay and Android Auto are wireless on the larger screen, and navigation with real-time traffic is included. An optional 19-speaker McIntosh audio system (Summit and above) delivers exceptional sound quality. The interface is intuitive, with large icons and quick response times. However, the system can occasionally freeze or lag when connecting multiple devices.
Off-Road Capabilities and 4x4 Systems
Four-Wheel-Drive Options
Jeep offers three distinct 4WD systems in the Grand Cherokee:
- Quadra-Trac I – Full-time single-speed system that automatically distributes torque between axles. Ideal for mild snow or gravel roads.
- Quadra-Trac II – Adds a two-speed transfer case with low-range gearing for steep, rocky climbs.
- Quadra-Drive II – Includes the two-speed transfer case plus an electronic rear limited-slip differential and (on some trims) a front axle disconnect for maximum traction.
The Trailhawk trim is the only model that comes standard with Quadra-Drive II, along with hill-descent control, skid plates, and 17-inch wheels with all-terrain tires. Its approach angle (30.2 degrees) and departure angle (28.2 degrees) are class-leading.
Air Suspension and Select-Terrain System
The Quadra-Lift air suspension, available on Limited and above, provides five ride-height settings: Normal, Off-Road 1 (1.3 in. lift), Off-Road 2 (2.6 in. lift), Park (lowered for entry/exit), and Aero (lowered at highway speeds). The Selec-Terrain system offers modes for Snow, Sand/Mud, and Rock (with low-range engaged). Combined, these features allow the Grand Cherokee to tackle challenging trails that would stop most crossover SUVs.
Trim-Level Comparisons and Which One to Buy
| Trim | Best For | Key Feature | Starting MSRP (2021) |
|---|---|---|---|
| Laredo | Budget buyers | Standard V6, low entry price | $34,200 |
| Altitude | Style seekers | Black accents, unique wheels | $36,400 |
| Limited | Daily comfort | Leather, power liftgate, heated seats | $39,700 |
| Trailhawk | Off-road adventurers | Quadra-Drive II, air suspension, skid plates | $46,400 |
| Overland | Luxury touring | Ventilated seats, wood trim, air suspension | $50,200 |
| Summit | Premium comfort | McIntosh audio, quilted leather, adaptive cruise | $55,400 |
| SRT | Performance | 6.4L V8, track-tuned suspension, Brembos | $72,200 |
| Trackhawk | Extreme speed | Supercharged V8, 707 hp, high-speed brakes | $88,500 |
For most buyers, the Limited or Trailhawk offers the best value. The Limited provides essential luxury and safety features without the high price of the Summit. The Trailhawk is unmatched among midsize SUVs for serious off-roading. If you rarely leave pavement and want maximum comfort, the Overland is a strong choice.
How the 2021 Grand Cherokee Compares to Competitors
Ford Explorer
The Ford Explorer offers a third row, a more modern interior, and better fuel economy with its turbocharged four-cylinder engine. However, the Grand Cherokee outclasses it in off-road ability, towing capacity with the V8, and interior luxury on higher trims. The Explorer’s 2021 base price is slightly lower, but its top trim (Platinum) costs less than the Grand Cherokee Summit.
Dodge Durango
Sharing the same platform, the Dodge Durango offers three rows and the same available 5.7L V8. It’s better for families who need seating for six or seven. The Grand Cherokee, however, feels more premium inside and offers the high-performance Trackhawk (the Durango SRT is no longer available for 2021). The Durango is a solid choice if you need more seats; otherwise, go with the Grand Cherokee.
Toyota 4Runner
The Toyota 4Runner is more rugged and reliable in extreme off-road conditions, with a body-on-frame design and legendary durability. But it rides much harsher on pavement, gets poor fuel economy (16 mpg combined with the V6), and its interior feels dated. The Grand Cherokee is far more refined for daily driving and still very capable off-road.
Honda Passport
The Honda Passport is more user-friendly, with better cargo space and a smoother ride, but it lacks a V8 option and low-range 4WD. Off-road capability is limited to dirt roads and light snow. The Grand Cherokee wins for towing and off-road prowess, while the Passport is better for families who never venture off pavement.
Fuel Economy and Cost of Ownership
Fuel economy is a weak point for the Grand Cherokee compared to newer unibody rivals. The V6 achieves 19 city/26 highway (22 combined), which is decent for the segment. The 5.7L V8 drops to 14/22 (17 combined), and the Trackhawk barely reaches 11/17 (13 combined). Premium fuel is required for the V8s. Over a typical 15,000-mile year, the V6 will cost about $2,200 in fuel, the V8 about $2,800, and the Trackhawk over $3,700 (assuming $3.00/gallon for regular gas, $3.50 for premium).
Insurance costs are slightly above average due to the high repair costs on luxury trims and the theft risk on SRT/Trackhawk models. Depreciation is moderate—about 45% after five years, which is typical for the segment. Resale value is strongest for the Trailhawk and Trackhawk, thanks to their niche appeal.
Conclusion: Should You Buy a 2021 Jeep Grand Cherokee?
The 2021 Jeep Grand Cherokee is a compelling choice for buyers who value a balance of on-road comfort, off-road capability, and premium features. Its wide trim range means there’s a model for nearly every budget and lifestyle. The reliability record is average, but proper maintenance and careful selection of a trim can mitigate many common issues. Strong warranties and aftermarket support help keep ownership manageable.
If you need a third row, look elsewhere (Explorer, Durango). If extreme off-roading is your priority, the 4Runner is more durable. But for the majority of SUV shoppers who want a comfortable daily driver that can also handle a weekend trail, the Grand Cherokee remains a solid bet.
