How much does the 2021 Jeep Gladiator cost?

Prices have softened 6.19% compared to this time last year, making it a favorable time to shop this model year.

Is the 2021 Jeep Gladiator a good car?

Yes — with a 5/5 user rating and a 7.17/10 expert rating, you’re looking at a model that resonates strongly with owners and still earns solid marks from our testers. The standout strength is Look and feel at 9/10.

Owners consistently praise its ruggedness, off-road capability, and unique design, and many also like its powerful performance and comfortable interior. The trade-offs are familiar: disappointing gas mileage and a price that can feel high, especially for the small bed size.

That lines up with the Gladiator’s use case as a lifestyle-focused midsize truck for you if you want open-air personality, customization, and trail-ready character more than conventional truck polish. With 33.2% of listings marked as good or great deals, the market still offers some room to shop selectively.

Is the 2021 Jeep Gladiator reliable?

Owners rate it 5/5, a strong signal of long-term satisfaction.

Owner feedback points to a truck that feels rugged, dependable, and built for long-term use, especially if you value its distinctive Jeep character. The diesel option adds substantial low-end torque and better fuel economy than the gas engine, while the truck’s off-road hardware reinforces its durable, go-anywhere personality.

Jeep also includes free scheduled maintenance for the first three years or 36,000 miles of ownership, which helps reduce early ownership costs. For used buyers, the main long-term risk is that the Gladiator’s specialized design and higher running costs can make upkeep and everyday use less forgiving than a more conventional pickup.

What should I look for when buying a used 2021 Jeep Gladiator?

Accident-free inventory is solid at 83.2% — always verify the vehicle history report.

You should still check the history report carefully and prioritize a pre-purchase inspection, especially if the truck has been used off-road or heavily modified. Focus on overall condition, because this model’s appeal often comes from equipment and usage history as much as mileage.

Key things to evaluate:

• Trim level: The Sport starts with a 5-inch display, crank windows, and the most basic top, while the Overland adds a more upscale interior and can be equipped with the top-shelf infotainment system. The Willys special edition adds a blacked-out grille, limited-slip rear differential, rock rails, and 32-inch all-terrain tires to the Sport or Sport S, while the High Altitude brings body-color detailing, black 20-inch wheels, and premium Nappa leather.
• Powertrain: You can choose a 3.6-liter gasoline V6 or a 3.0-liter turbo-diesel V6. The diesel brings 260 horsepower and 442 pound-feet of torque, plus stronger low-end pull and better fuel economy than the gas engine.
• Safety package: The truck comes standard with a reversing camera, while available driver-assistance features include adaptive cruise control, forward collision warning, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, and automatic high beams. Some of these features depend on trim and equipment.
• Infotainment: The standard setup uses a 5-inch display with Bluetooth, voice text reply for Android devices, and SiriusXM satellite radio. A 7-inch Uconnect 4 system adds Apple CarPlay and Android Auto, and the 8.4-inch Uconnect 4C system adds navigation, SiriusXM Guardian connected services, remote engine starting, a WiFi hotspot, and an Alpine premium sound system.
• Fuel efficiency: The diesel returned 22.6 mpg in testing and is estimated at 24 mpg combined, while the standard V6 returned 20.3 mpg in a prior highway-heavy test.

Which 2021 Jeep Gladiator trim should I buy?

The 2021 Jeep Gladiator is offered in 5 trim levels: Sport, Sport S, Overland, Willys, and High Altitude.

Here's the short version:

• Sport: This is the entry point, and it gives you the most basic setup with a 5-inch display, crank windows, and the simplest top. It makes sense if you want the lowest starting price and plan to build from there.
• Sport S: This is the best-value trim for many shoppers because it unlocks the 7-inch Uconnect 4 system with Apple CarPlay and Android Auto. It also serves as one of the trims eligible for the Willys special edition package.
• Overland: This trim moves the Gladiator toward a more upscale feel, and it can be paired with the 8.4-inch Uconnect 4C system, navigation, connected services, remote start, and the Alpine premium sound system. It’s a strong pick if you want comfort and tech.
• Willys: This is the choice if you want a more rugged look and added trail hardware, including a limited-slip rear differential, rock rails, and 32-inch all-terrain tires. It’s the most characterful option without jumping to the top of the lineup.
• High Altitude: This is the luxury-leaning trim, with body-color detailing, black 20-inch wheels, and premium Nappa leather. Choose it if you want the most polished Gladiator experience.

The safety package is still limited at the lower end, so if driver-assistance features matter to you, make sure the truck you’re considering is equipped accordingly.

Is now a good time to buy a used 2021 Jeep Gladiator?

This is a moderate market for selective buyers, so you can shop with some leverage if you’re patient.

• Deal availability: 33.2% of listings are priced as good or great deals.
• Inventory: There are 4,974 listings available.
• Price trend: Prices have softened 6.19% compared with last year.
• Clean inventory: 83.2% of listings are accident-free.

If you find a listing below $30,670, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 Jeep Gladiator's resale value?

The current average of $31,277 sits slightly below last year's $33,341.

That decline suggests the market has cooled enough to give you a better entry point now, but it also means future sellers may need to price competitively to stand out. If you buy well and keep the truck in strong condition, you can help protect value when it’s time to sell.

The Gladiator’s distinctive appeal can support demand, especially among buyers who want its open-air personality and off-road image. Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

Is the 2021 Jeep Gladiator safe?

The 2021 Jeep Gladiator earns a four-star frontal-impact rating from NHTSA and three-star rollover resistance ratings.

It earns a 7/10 safety score from our experts.

You get a reversing camera as standard, and available driver-assistance features include adaptive cruise control, forward collision warning, automatic emergency braking, blind-spot monitoring, rear cross-traffic alert, and automatic high beams. The blind-spot monitoring system is especially useful because the side mirrors are narrow.

The main caveat is that standard safety equipment is sparse, so you’ll want to verify exactly which assistance features are installed on any used example you’re considering.

Should I buy a 2021 Jeep Gladiator or consider a different year?

If you're weighing the 2021 against nearby model years, here's how to think about it:

Choose the 2021 if:

• 33.2% of listings are priced as good or great deals.
• Accident-free inventory is solid at 83.2% — always verify the vehicle history report.
• Price trend: Prices have softened 6.19% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The 2021 adds a new turbo-diesel engine option, available full-time four-wheel drive, fresh special-edition models, and free scheduled maintenance.

Consider the 2020 if:

• At $28,164, the 2020 costs less than the current year's $31,277 average.
• It blends midsize pickup utility with strong off-road ability.

The bottom line: If you want the best mix of features, market availability, and owner satisfaction, the 2021 is the stronger all-around pick. If your priority is spending less up front, the 2020 is the better value-oriented alternative, especially if you can live without the 2021 updates.
