Used 2021 GMC Yukon for Sale nearMidland, TX

How much does the 2021 GMC Yukon cost?

Prices have softened 14.18% compared to this time last year, making it a favorable time to shop this model year.

There are 2,211 listings available, which suggests solid inventory for shoppers comparing prices and trims.

If you find a listing below $42,633.96, 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 a 7.67/10 expert rating. 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 owners say it stands out in its class.

The trade-offs are clear: the expert review calls out poor fuel economy and uncomfortable seats, along with interior materials that can feel cheap. Even so, the Yukon’s spacious third row and plenty of cargo space make it a strong fit if you want a large SUV with a more refined, capable feel.

With 30.3% 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 that feels reliable, dependable, and comfortable to live with over time. That kind of praise matters when you’re shopping used, because it suggests the Yukon is the sort of SUV owners feel confident keeping for the long haul.

The expert review also emphasizes that the redesigned Yukon brings meaningful improvements in space, ride quality, and technology, which supports the sense that it is built to be a capable daily driver. The overall ownership risk for used buyers is mainly tied to condition and maintenance history, so a careful pre-purchase inspection still matters.

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

Accident-free inventory is solid at 77% — always verify the vehicle history report.

You should still check the history report on any specific listing, because accident-free inventory is only a starting point. Prioritize a thorough inspection of the cabin, suspension, and electronics, since this is a large, feature-rich SUV where condition can vary a lot from one example to the next. Focus especially on how the vehicle drives, how the tech works, and whether the interior shows the kind of wear you’d expect from family use.

Key things to evaluate:

• Trim level: The SLE, SLT, AT4, and Denali each bring a different mix of refinement and equipment. The base setup includes the core safety and infotainment features, while SLT adds more driver-assistance tech, and Denali brings the most upscale cabin treatment and additional convenience features.
• Powertrain: A 355-horsepower 5.3-liter V8 is standard on most trims, while the 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, and the review notes that the larger V8 delivers strong acceleration but not strong fuel economy.
• 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 automatic crash response and crisis assistance through OnStar. Starting with SLT, you also get blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. Rear pedestrian alert is available on SLT and AT4 and standard on Denali, while adaptive cruise control and enhanced automatic emergency braking are reserved for Denali.
• 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 Performance Series audio system, and rear-seat entertainment with dual 12.6-inch displays.
• Fuel efficiency: The review says fuel economy can worsen rather than improve in some cases, and the 6.2-liter V8 with 4WD is rated at 14 mpg city, 19 highway, and 16 combined.

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:

• SLE: This is the entry point if you want the Yukon’s space, standard safety tech, and core infotainment without paying for extra luxury features. It makes sense if you care most about value and want the redesigned cabin and technology without stretching the budget.
• SLT: This is the best-value trim for many shoppers because it adds important driver-assistance upgrades, including blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance. If you want a more complete daily-driver setup without jumping to Denali pricing, this is the trim to target.
• AT4: Choose this if you want the off-road-oriented version, since it adds improved approach angle, skid plates, and all-terrain tires. It is the right fit if your use case includes rougher roads or you simply want the more rugged look and hardware.
• Denali: This is the luxury pick, with the exclusive 6.2-liter V8, a more upscale interior, and the most available convenience and safety content. It suits you best if you want the most refined Yukon and are willing to pay for it.

For safety, note that adaptive cruise control and enhanced automatic emergency braking are only available on Denali.

What is the 2021 GMC Yukon's resale value?

The current average of $42,614 sits slightly below last year's $49,653.

That price drop 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 means resale value will depend heavily on how well you preserve condition, mileage, and service history.

The Yukon’s strong owner satisfaction helps support demand, especially among shoppers who want a spacious, premium-feeling full-size SUV. If you buy well and keep the vehicle in good shape, that can help cushion depreciation over time.

Vehicles with strong owner satisfaction ratings, like this model year's 5/5, tend to retain buyer demand, which supports resale value over time.

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:

• 30.3% of listings are priced as good or great deals.
• Accident-free inventory is solid at 77% — always verify the vehicle history report.
• Price trend: Prices have softened 14.18% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesign brings more space, better ride quality, and a major technology upgrade.

Consider the 2022 if:

• At $47,724, the 2022 costs more than the current year's $42,614 average.
• It adds a standard 12-inch driver information center and enhanced connectivity.

The bottom line: The 2021 is the better buy if you want the redesigned Yukon at a lower price and can live with its fuel-economy and value trade-offs. If you want the newer-year updates and are less price-sensitive, the 2022 is worth a look, but the 2021 gives you the stronger value case right now.
