How much does the 2021 GMC Yukon cost?

Prices have softened 13.53% compared to this time last year, making it a favorable time to shop this model year.

There are 2,220 listings available, which suggests solid inventory for shoppers comparing trims and conditions.

If you find a listing below $43,026.52, that's toward the low end of the year-round range and worth acting on quickly.

Is the 2021 GMC Yukon a good car?

Yes — you’re looking at a 5/5 user-rated SUV with an expert score of 7.67/10. The model scores 9/10 across Look and feel, Technology, and Safety.

Owners consistently praise the luxurious feel, spacious interior, and impressive tech features. The ride is also described as extremely comfortable, and many shoppers say it stands out in its class. On the trade-off side, some owners mention minor comfort-related wishes, including more support handles and air-conditioned seats.

That lines up with the Yukon’s use case as a full-size family SUV that balances comfort, cargo room, and premium touches. It also fits buyers who want a near-luxury feel without moving up to a luxury badge.

With 32.8% of listings marked as good or great deals, you have a decent chance of finding a competitive offer if you shop carefully.

Is the 2021 GMC Yukon reliable?

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

The owner feedback points to a vehicle people feel good about living with over time, especially because of the spacious cabin, upscale feel, and strong tech package. The expert evaluation also emphasizes improved passenger space, improved cargo space, and a ride-and-handling upgrade from the redesign, which supports the sense that this is a well-sorted SUV for daily use.

The powertrain and chassis changes also suggest a durable, confidence-inspiring setup for long-term ownership. For used buyers, the main risk is less about the concept and more about finding a well-kept example that hasn’t been worn down by heavy family or towing use.

What should I look for when buying a used 2021 GMC Yukon?

Accident-free inventory is solid at 78.3% — always verify the vehicle history report.

You should still check the history report carefully, because a clean listing percentage does not replace a proper records review. Prioritize a pre-purchase inspection that focuses on ride quality, interior wear, and any signs of hard use. Given the Yukon’s size and premium equipment, condition matters a lot more than mileage alone.

Key things to evaluate:

• Trim level: The SLE, SLT, AT4, and Denali trims are explicitly identified, and the base setup starts with standard safety and tech features that leave some upgrades for higher trims. Starting with SLT, you gain blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance, while Denali adds rear pedestrian alert and adaptive cruise control.
• Powertrain: The standard engine is a 355-horsepower 5.3-liter V8 on most trims, while Denali gets a 420-horsepower 6.2-liter V8. A 3.0-liter turbo-diesel inline six-cylinder is also mentioned as an option for most versions except AT4. Fuel economy is a weak point, especially with the 6.2-liter V8.
• Safety package: Standard equipment includes forward collision warning, daytime pedestrian detection, automatic emergency braking below 50 mph, automatic high-beam headlights, Teen Driver, a rear-seat reminder, and OnStar crash response and crisis assistance. SLT and above add blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. Denali gets rear pedestrian alert and enhanced automatic emergency braking above 50 mph.
• Infotainment: Every 2021 Yukon gets a 10.2-inch touchscreen with wireless Apple CarPlay, wireless Android Auto, Amazon Alexa integration, over-the-air updates, and access to connected services. Available upgrades include wireless charging, navigation, a 14-speaker Bose system, and rear-seat media with dual 12.6-inch displays.
• Fuel efficiency: The 6.2-liter V8 with 4WD is EPA-rated at 14 mpg city, 19 highway, and 16 combined. In testing, it returned 14.4 mpg on one loop and 16.2 mpg on another.

Which 2021 GMC Yukon trim should I buy?

The 2021 GMC Yukon is offered in 4 trim levels: SLE, SLT, AT4, and Denali.

Here's the short version:

• Base trim: The SLE gives you the core Yukon experience, but you miss out on the added driver-assistance features that start with SLT, along with the more upscale cabin touches found higher up the range.
• Sweet-spot trim: The SLT is the best value if you want the most important safety upgrades without jumping all the way to Denali pricing. It adds blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance.
• Premium/top trim: Denali is the luxury pick, with the 6.2-liter V8, rear pedestrian alert, adaptive cruise control, enhanced automatic emergency braking, and the most upscale interior presentation.
• Off-road trim: AT4 is the one to choose if you want the more rugged setup, including improved approach angle, skid plates, and all-terrain tires.

The safety-package progression is straightforward: standard features are strong, SLT adds meaningful everyday protection, and Denali brings the most advanced driver assistance.

Is now a good time to buy a used 2021 GMC Yukon?

This is a moderate market for selective buyers, so you can shop with some leverage if you know what you want.

• Deal availability: 32.8% of listings are priced as good or great deals.
• Inventory: There are 2,220 listings available.
• Price trend: Prices have softened 13.53% compared with last year.
• Clean inventory: 78.3% of listings are accident-free.

If you find a listing below $43,026.52, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2021 GMC Yukon's resale value?

The current average of $43,017 sits slightly below last year's $49,746.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable point in the cycle. For a future seller, that also means resale upside may depend more on condition, trim, and equipment than on broad market momentum. Well-kept examples with desirable features should hold attention better than average ones.

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 GMC Yukon safe?

It earns a 9/10 safety score from our experts.

Standard safety equipment includes forward collision warning, daytime pedestrian detection, automatic emergency braking below 50 mph, automatic high-beam headlights, Teen Driver, a rear-seat reminder, and OnStar crash response and crisis assistance. Starting with SLT, you also get blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. Denali adds rear pedestrian alert and adaptive cruise control, plus enhanced automatic emergency braking that works above 50 mph.

The main caveat is that crash-test ratings were unavailable in the source material, so you should lean more heavily on the Yukon’s ADAS content and the condition of any used example you inspect.

Should I buy a 2021 GMC Yukon 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:

• 32.8% of listings are priced as good or great deals.
• Accident-free inventory is solid at 78.3% — always verify the vehicle history report.
• Price trend: Prices have softened 13.53% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesign brings more passenger space, more cargo space, and a smoother ride.

Consider the 2022 if:

• At $48,193, the 2022 costs more than the current year's $43,017 average.
• It adds a standard 12-inch driver information center and improved connectivity.

The bottom line: If you want the better value, the 2021 is the smarter buy because it delivers the redesign benefits at a lower average price. If you’re willing to pay more for a newer model with a few added tech refinements, the 2022 is the cleaner step up. For most price-sensitive shoppers, the 2021 is the stronger starting point.
