How much does the 2021 GMC Yukon cost?

Prices have softened 13.09% compared to this time last year, making it a favorable time to shop this model year.

There are 2,206 listings available, which suggests solid inventory for comparison shopping.

If you find a listing below $43,303.73, 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 spacious interior, luxurious feel, 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 clear: the expert review calls out poor fuel economy and less-than-ideal towing capacity compared with rivals. The overview also frames it as a strong fit if you want a full-size SUV with family-friendly space and upscale utility.

With 32.8% of listings marked as good or great deals, you have room to shop selectively.

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 dependable and trouble-free in everyday use, with the kind of comfort and refinement people expect to keep enjoying over time. The expert review also emphasizes that the redesigned Yukon improves passenger space and cargo space while delivering a more composed ride, which supports confidence in long-term ownership.

The expert notes that the Yukon’s ride and handling improve thanks to the independent rear suspension and available adaptive damping, and the technology package is designed to stay current with over-the-air updates. That said, used buyers should still pay close attention to maintenance history and overall condition, since a large, feature-rich SUV can become expensive if prior care was inconsistent.

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

Accident-free inventory is solid at 78.9% — always verify the vehicle history report.

You should still check for prior damage, confirm service records, and prioritize a thorough inspection of the suspension, brakes, electronics, and interior wear. Because this is a large SUV with lots of available technology, it’s smart to test every major feature during the drive and make sure the cabin, seats, and controls all match the seller’s description.

Key things to evaluate:

• Trim level: The base SLE starts the lineup, while SLT adds more convenience and driver-assistance equipment. AT4 is the off-road-focused choice, and Denali brings the most upscale cabin treatment and additional features.
• Powertrain: A 355-horsepower 5.3-liter V8 is standard on all but Denali, which 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 fuel economy is not the 6.2-liter’s strength.
• 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, while Denali gets rear pedestrian alert and adaptive cruise control.
• 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 expert review reports 14.4 mpg on one mixed test loop and 16.2 mpg on a shorter solo loop. It also cites EPA ratings of 14 mpg city, 19 highway, and 16 combined for the 6.2-liter V8 with 4WD.

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 Yukon’s core space and standard safety tech, but it misses the extra driver-assistance features that start showing up higher in the lineup.
• Sweet-spot trim: The SLT is the best value if you want the added 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 most upscale cabin presentation, exclusive interior design, and the strongest standard engine.
• Off-road trim: AT4 is the one to choose if you want the improved approach angle, skid plates, and all-terrain tires for more serious trail use.

For safety-package shoppers, Denali is the trim that adds rear pedestrian alert and adaptive cruise control.

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

This is a moderate buyer’s market, so you can shop selectively and still find worthwhile listings.

• Deal availability: 32.8% of listings are priced as good or great deals.
• Inventory: There are 2,206 listings available.
• Price trend: Prices have softened 13.09% compared with last year.

If you find a listing below $43,303.73, 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 $43,294 sits slightly below last year's $49,818.

That price movement suggests the Yukon has already absorbed a meaningful amount of depreciation, which can help future sellers if the market stabilizes. If you buy at the right price and keep the vehicle in strong condition, you may have a better chance of limiting your loss later. Strong demand for a spacious, well-equipped full-size SUV can also help support resale interest.

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.

GMC equips the 2021 Yukon with 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, while Denali adds rear pedestrian alert and adaptive cruise control.

The expert review also notes that the ADAS works in a subtle, polished way that encourages you to leave it on. One caveat is that crash-test ratings were unavailable in the review material.

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 78.9% — always verify the vehicle history report.
• Price trend: Prices have softened 13.09% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesign brings more passenger space, better ride quality, and a major tech upgrade.

Consider the 2022 if:

• At $48,272, the 2022 costs more than the current year's $43,294 average.
• It adds a standard 12-inch driver information center and enhanced connectivity.

The bottom line: If you want the better value play, the 2021 is the smarter starting point because prices have eased and inventory is healthy. If you’re willing to pay more for a slightly newer model with added connectivity, the 2022 is the cleaner upgrade path. For most price-sensitive buyers, the 2021 delivers the stronger balance of features, satisfaction, and market value.
