Used 2021 GMC Yukon for Sale nearAmarillo, TX

How much does the 2021 GMC Yukon cost?

Prices have softened 14.25% compared to this time last year, making it a favorable time to shop this model year.

There are 2,311 listings available, which suggests solid inventory for comparison shopping.

If you find a listing below $42,434.62, 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 overall. 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 described as extremely comfortable, and many owners say it stands out in its class. Those strengths line up well with the Yukon’s use case as a large, premium-leaning family SUV with plenty of room and a refined feel.

The trade-offs are real, though: the expert review calls out poor fuel economy and notes that the seats can be uncomfortable, while interior materials can feel cheap. Even so, the Yukon’s spacious third row and cargo space make it a strong fit if you want full-size utility with a more upscale presentation.

With 33.5% of listings marked as good or great deals, there’s a meaningful share of attractive inventory to consider.

Is the 2021 GMC Yukon reliable?

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

User feedback points to a dependable, trouble-free ownership experience, with owners especially confident in the Yukon’s long-term appeal. The expert review also emphasizes that the SUV’s substantial capability and refined ride make it feel like a vehicle you can count on for regular family duty.

The powertrain and chassis changes support that impression, with the redesigned platform and suspension setup aimed at improving everyday durability and composure. The maintenance and ownership picture also benefits from the model’s broad mainstream serviceability, which helps keep long-term ownership risk manageable for used buyers.

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

Accident-free inventory is solid at 77.6% — always verify the vehicle history report.

You should still check the history report carefully, because accident-free status does not replace a full inspection. Pay close attention to seat comfort, interior wear, and whether the vehicle’s equipment matches the trim level you expect. It also makes sense to confirm that the technology and driver-assistance features work properly, since this model leans heavily on its upgraded electronics.

Key things to evaluate:

• Trim level: The lineup ranges from more basic SLE and SLT versions to the AT4 and Denali, and the base trims miss some of the upscale touches that make the Yukon feel special. Denali brings the most premium cabin treatment, while AT4 adds a more adventurous character.
• Powertrain: You can get a standard 355-horsepower 5.3-liter V8, 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, and the expert review notes that the 6.2-liter delivers strong acceleration but not great fuel economy.
• Safety package: Standard equipment includes forward collision warning, daytime pedestrian detection, automatic emergency braking, and automatic high-beam headlights. Starting with SLT, you also get blind-spot warning, rear cross-traffic warning, lane-departure warning, and lane-keeping assistance, 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 audio system, and rear-seat entertainment with dual 12.6-inch displays.
• Fuel efficiency: The expert review reports 14.4 mpg on one test loop and 16.2 mpg on another, while the 4WD 6.2-liter V8 is EPA-rated at 14 mpg city, 19 mpg highway, and 16 mpg 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, so it makes sense if you want the Yukon’s space and core tech without paying for the more upscale trim content. It gives you the basics, but you’ll miss some of the comfort and convenience upgrades that make the higher trims feel more premium.
• SLT: This is the best-value trim for many shoppers because it adds important safety equipment and a more complete feature set without jumping all the way to Denali pricing. It’s the trim where the Yukon starts to feel more fully equipped for daily family use.
• AT4: Choose this if you want the more adventurous setup and the off-road-oriented hardware described in the review, including improved approach angle, skid plates, and all-terrain tires. It’s the right pick if your priorities lean toward capability and a tougher look.
• Denali: This is the luxury choice, with the most distinctive cabin, the 6.2-liter V8, and the richest feature content. It’s the trim to buy if you want the Yukon at its most premium and don’t mind paying for it.

Adaptive cruise control and enhanced automatic emergency braking are standard only on Denali.

What is the 2021 GMC Yukon's resale value?

The current average of $42,422 sits slightly below last year's $49,470.

That price drop suggests the Yukon has already absorbed a meaningful amount of depreciation, which can help future sellers if they buy at the right price today. A lower entry cost can leave more room for the vehicle to hold value relative to what you pay. Strong demand for a spacious, well-equipped full-size SUV can also help support resale interest 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.

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, automatic high-beam headlights, Teen Driver parental report card technology, a rear-seat reminder system, and automatic crash response and crisis assistance through an active OnStar subscription.

Starting with SLT trim, 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.

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:

• 33.5% of listings are priced as good or great deals.
• Accident-free inventory is solid at 77.6% — always verify the vehicle history report.
• Price trend: Prices have softened 14.25% 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 $47,501, the 2022 costs more than the current year's $42,422 average.
• It adds a standard 12-inch driver information center.

The bottom line: If you want the better value, the 2021 is the smarter buy because it delivers the redesigned Yukon experience at a lower average price. If you’re willing to pay more for a newer model year and the added driver-information upgrade, the 2022 is worth a look.
