How much does the 2021 GMC Yukon cost?

Prices have softened 13.42% compared to this time last year, making it a favorable time to shop this model year.

There are 2,263 listings available, which suggests you have meaningful inventory to compare across trims and conditions.

If you find a listing below $43,142.27, 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 described as extremely comfortable, and many shoppers see it as standing out in its class. The main trade-offs are minor comfort suggestions such as more support handles and air-conditioned seats, along with some expert notes about fuel economy and a few comfort-related drawbacks.

That lines up well with the Yukon’s use case as a full-size SUV for families who want space, premium touches, and modern tech in one package. With 33.1% of listings marked as good or great deals, there is still 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 people feel good about living with over time, especially because it comes across as dependable, comfortable, and well suited to long-term use. The expert review also reinforces that sense of durability by describing the Yukon as capable and composed in everyday driving, with strong acceleration and a refined ride.

The maintenance and ownership picture is helped by the Yukon’s modern tech and broad feature set, though premium equipment can raise running costs. For used buyers, the main long-term risk is that a well-equipped example may be more expensive to keep in top shape than a simpler SUV.

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 proper inspection. Pay close attention to tire wear, brake feel, suspension condition, and whether the electronics and driver-assistance features work as intended. If you are shopping a higher-trim example, make sure the luxury and tech features are fully functional, since those systems are part of what you are paying for.

Key things to evaluate:

• Trim level: The standard Yukon lineup includes SLE, SLT, AT4, and Denali. The base setup starts with core safety tech, but SLT adds 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.
• Powertrain: Three engines are available. Most trims use a 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 every Yukon except the AT4. The 6.2-liter delivers strong acceleration, but fuel economy is not its strength.
• Safety package: Standard equipment includes forward collision warning, daytime pedestrian detection, automatic emergency braking below 50 mph, automatic high-beam headlights, Teen Driver technology, a rear-seat reminder, and crash response through OnStar. SLT and above add 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.
• Infotainment: All 2021 Yukons get 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 audio system, and rear-seat entertainment 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. The expert review also notes that fuel economy worsens compared with the previous generation in some configurations.

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: 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 treatment found higher up the range.
• Sweet-spot trim: SLT is the best value if you want the strongest balance of features and price, because it adds 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. It brings the most upscale interior presentation, the 6.2-liter V8, rear pedestrian alert, adaptive cruise control, and enhanced automatic emergency braking.
• Off-road trim: AT4 is the one to choose if you want the off-road-focused setup with improved approach angle, skid plates, and all-terrain tires.

The safety package starts with useful standard driver aids, but SLT is where the feature set becomes much more complete for everyday driving.

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

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

• Deal availability: 33.1% of listings are priced as good or great deals.
• Inventory: There are 2,263 listings available.
• Price trend: Prices have softened 13.42% compared with last year.
• Clean inventory: 77.6% of listings are accident-free.

If you find a listing below $43,142.27, 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 $43,129 sits slightly below last year's $49,811.

That price movement suggests the Yukon has already absorbed a meaningful amount of depreciation, which can help future resale stability if you buy at the right price. If you choose a well-kept example with desirable equipment, you may be better positioned than someone who buys at the top of the market. Strong demand for roomy, premium full-size SUVs can also help support values 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.

Standard safety equipment includes forward collision warning, daytime pedestrian detection, automatic emergency braking below 50 mph, automatic high-beam headlights, Teen Driver technology, 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. Denali adds rear pedestrian alert, adaptive cruise control, and enhanced automatic emergency braking that works above 50 mph.

The expert review notes that the ADAS works smoothly and subtly, which is a good sign for everyday use. Crash-test ratings were unavailable in the review material, so you should focus on the available driver-assistance equipment and the trim level you are considering.

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:

• 33.1% 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 13.42% compared with last year.
• Owners rate it 5/5 — a strong satisfaction signal.
• The redesign improves passenger space, cargo room, ride quality, handling, and technology.

Consider the 2022 if:

• At $48,198, the 2022 costs more than the current year's $43,129 average.
• It adds a standard 12-inch driver information center and improved connectivity.

The bottom line: If you want the best mix of price, space, and modern features, the 2021 is the smarter buy. If you are willing to pay more for a newer model-year update and slightly improved connectivity, the 2022 is worth a look. For most price-sensitive shoppers, the 2021 offers the stronger value right now.
