How much does the 2021 GMC Yukon cost?

Prices have softened 12.90% compared to this time last year, making it a favorable time to shop this model year.

There are 2,183 listings available, which suggests you have a healthy amount of inventory to compare.

If you find a listing below $43,433.31, 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 — the 2021 GMC Yukon earns a 5/5 user rating, and our experts give it 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. They also describe the ride as extremely comfortable, and many say it stands out in its class.

The trade-offs are a poor fuel economy and uncomfortable seats, along with some feedback that the interior materials feel cheap.

For you, that means the Yukon makes the most sense if you want a full-size SUV that leans into comfort, space, and upscale features rather than efficiency or bargain pricing.

With 32.3% of listings marked as good or great deals, there’s still meaningful value in the market 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 that feels reliable, comfortable, and well suited to long-term use, with many shoppers appreciating how confidently it fits family duty. The expert review also emphasizes that the redesigned Yukon improves passenger space and cargo space, which supports everyday dependability.

The powertrain and chassis setup are described as robust, with strong acceleration and a ride that benefits from the independent rear suspension and available adaptive damping. The tech package also includes over-the-air updates, which helps keep the system current over time.

If you’re buying used, the main long-term risk is making sure prior use hasn’t worn down the seats, fuel economy, or premium features you’re paying for.

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

Accident-free inventory is solid at 79% — always verify the vehicle history report.

You should still check the report carefully, because a clean listing percentage doesn’t replace a proper history review. Prioritize a pre-purchase inspection, especially on a large SUV where suspension, brakes, and interior wear can vary a lot by use. Focus on seat condition, infotainment operation, and whether the vehicle’s features match the trim you’re considering.

Key things to evaluate:

• Trim level: The base SLE gives you the redesigned Yukon experience, but the SLT adds blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. Denali brings its own exclusive dashboard design, real wood trim, leather-wrapped panels, unique stitching and piping, and a more upscale cabin.
• Powertrain: The standard 5.3-liter V8 is rated at 355 horsepower, while the Denali’s exclusive 6.2-liter V8 makes 420 horsepower and pairs with a ten-speed automatic. A 3.0-liter turbo-diesel inline six-cylinder is also mentioned as an option for most versions.
• Safety package: Standard driver assistance includes forward collision warning, daytime pedestrian detection, automatic emergency braking below 50 mph, automatic high-beam headlights, Teen Driver, 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, while Denali adds rear pedestrian alert, adaptive cruise control, 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. Higher trims can add 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 a shorter second loop.

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 is the starting point, but you give up the extra driver-assistance features that arrive on SLT and above, along with the more upscale cabin treatment found higher in the range.
• Sweet-spot trim: The SLT is the best value if you want the added safety tech, because it brings blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance without jumping all the way to Denali pricing.
• Premium/top trim: Denali is the luxury pick, with the exclusive dashboard design, real wood trim, leather-wrapped panels, unique stitching and piping, adaptive cruise control, and enhanced automatic emergency braking.
• Off-road trim: AT4 is the one to choose if you want the off-road hardware, including improved approach angle, skid plates, and all-terrain tires.

The safety package starts with forward collision warning, daytime pedestrian detection, automatic emergency braking below 50 mph, automatic high-beam headlights, Teen Driver, rear-seat reminder, and OnStar crash response and crisis assistance.

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

The market looks selective rather than overheated, so you can shop with some leverage if you’re patient.

• Deal availability: 32.3% of listings are priced as good or great deals.
• Inventory: There are 2,183 listings available.
• Price trend: Prices have softened 12.90% compared with last year.
• Clean inventory: 79.0% of listings are accident-free.

If you find a listing below $43,433.31, 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 $43,396 sits slightly below last year's $49,824.

That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable point in the cycle. If you plan to resell later, the current discount may limit some near-term depreciation pressure compared with a model that is still priced at its peak.

The Yukon’s strong owner satisfaction and upscale appeal should help support demand among shoppers who want a full-size SUV with space and premium features. That said, resale will still depend heavily on mileage, condition, and how well the vehicle has been maintained.

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.

The Yukon comes with a broad set of standard driver-assistance features, including forward collision warning, daytime pedestrian detection, automatic emergency braking below 50 mph, automatic high-beam headlights, Teen Driver, rear-seat reminder, and OnStar crash response and crisis assistance.

Starting with SLT trim, you also get blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. Denali adds rear pedestrian alert, adaptive cruise control, and enhanced automatic emergency braking that works above 50 mph.

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:

• 32.3% of listings are priced as good or great deals.
• Accident-free inventory is solid at 79% — always verify the vehicle history report.
• Price trend: Prices have softened 12.90% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesign brings more passenger space, more cargo space, and a major technology upgrade.

Consider the 2022 if:

• At $48,232, the 2022 costs more than the current year's $43,396 average.
• It adds a standard 12-inch driver information center and improved connectivity.

The bottom line: If you want the best mix of price relief, strong owner satisfaction, and the redesigned Yukon’s space and tech upgrades, the 2021 is the smarter buy. If you’re willing to pay more for a newer model-year update and slightly improved connectivity, the 2022 is worth a look, especially if you’re less price-sensitive.
