CarGurus Analysis: 2021 GMC Yukon XL
Summary
With 1,546 currently listed for sale and an average price of $39,910, 36.2% of 2021 GMC Yukon XL listings on CarGurus are rated as good or great deals.
Favorably reviewed: Owners rated the 2021 GMC Yukon XL 5 / 5 stars.
73.9% of 2021 GMC Yukon XL listings on CarGurus are accident free.
Why it stands out
The 2021 GMC Yukon XL stands out as a full-size SUV that combines serious space with a more modern driving feel than older versions. For 2021, it gained an independent rear suspension that replaced the old solid rear axle, and GMC says that change greatly improved ride and handling while also helping create a more comfortable third-row seat and additional cargo capacity. The XL body style still adds more than a foot between the front and rear axles, so it remains the version to choose if passenger room and cargo space are the priorities.
It also arrived with a broad spread of features and trims that let buyers tailor it to different needs. The base SLE included an 18-inch wheel setup, LED headlamps, a 10.2-inch touchscreen with wireless Apple CarPlay and Android Auto, eight-passenger seating, and automatic emergency braking with forward-collision warning. Higher trims added conveniences such as a power liftgate, heated and ventilated front seats, leather seating surfaces, a Bose audio system, and available second-row bucket seats, while the AT4 focused on off-road hardware like four-wheel drive, skid plates, front recovery hooks, and all-terrain tires. At the top, the Denali brought a standard 420-horsepower 6.2L V8, and the optional Denali Ultimate package layered on features such as 22-inch wheels, a rear-seat entertainment system, and power retractable side steps.
For buyers, the appeal is straightforward: the 2021 GMC Yukon XL offers a rare mix of luxury, capability, and genuine three-row usefulness. Owners also praise its spacious interior, comfort on long trips, and upscale feel. The tradeoffs are the expected ones for a vehicle this large, including poor fuel economy and some complaints about braking, but for shoppers who need maximum room without giving up refinement, it is a compelling choice.

Getting the diesel was the best decision! Far superior to the gasoline engine options.

The vehicle provides passenger comfort for lengthy travel. The driver is provided information within his view for safe driving and locating turns. There is abundant storage room and the third row allows a large group to travel together

Reviewed a 2021 GMC Yukon XL on Feb 7, 2023
I am really surprised with this vehicle. It’s massive, but even as big as it is, it’s very agile and easy to drive. The engine has enough power to push this beast in and out of right situations. I do wish the brakes had a bit more to them but all in all fun to drive. Doesn’t feel like a us. The interior is well appointed and looks fantastic.

How much does the 2021 GMC Yukon XL cost?
| Metric | Value |
|---|---|
| Current Average Price | $39,829 |
| Year-Round Low | $39,829 |
| Year-Round High | $46,413 |
| Average Price a Year Ago | $46,413 |
| Change vs. Last Year | −14.19% |
Prices have softened 14.19% compared to this time last year, making it a favorable time to shop this model year.
There are 1,527 listings available, which suggests you have a meaningful amount of inventory to compare.
Is the 2021 GMC Yukon XL a good car?
Yes — the 2021 GMC Yukon XL earns a 5/5 user rating, which points to strong owner satisfaction. Owners consistently praise its luxury feel, spacious interior, and comfort on long trips, and many also like how agile it feels despite its large size. For you, that makes it a strong fit if you want a full-size SUV with serious passenger and cargo space, especially if you value a more upscale experience. With 32.8% of listings marked as good or great deals, there is still some room to shop selectively.
Is the 2021 GMC Yukon XL reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The owner feedback also emphasizes that it feels dependable and comfortable for long trips, with many drivers saying they can count on its spaciousness and upscale character. Some buyers do mention concerns about the brakes and prefer the diesel option over the gasoline engine choices, so you should pay close attention to maintenance history and how the vehicle has been used. For used buyers, the main long-term ownership risk is making sure a large, heavily used SUV has been cared for properly.
What should I look for when buying a used 2021 GMC Yukon XL?
At 74.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
You should start with a vehicle history report and confirm whether any prior damage was repaired properly. A pre-purchase inspection should focus on braking performance, suspension condition, and signs of heavy family or towing use. Because this is a large, premium SUV, you will want to pay close attention to interior wear, electronics, and overall maintenance records.
Is now a good time to buy a used 2021 GMC Yukon XL?
This looks like a moderate, selective buyer's market, so you can shop carefully and still find worthwhile options.
- Deal availability: 32.8% of listings are priced as good or great deals.
- Inventory: There are 1,527 listings available.
- Price trend: Prices have softened 14.19% compared with last year.
- Clean inventory: 74.4% of listings are accident-free.
If you find a listing below $39,829, that's toward the low end of the year-round range and worth acting on quickly.
What is the 2021 GMC Yukon XL's resale value?
The current average of $39,829 sits slightly below last year's $46,413.
That price movement suggests the market has already adjusted downward, which can help you buy at a more favorable point if you plan to keep the vehicle for several years. For a future seller, the key question is whether the SUV continues to hold demand as a spacious, upscale family hauler. Well-kept examples should remain attractive because buyers in this segment often prioritize condition, equipment, and comfort over age alone.
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 XL 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.
- At 74.4% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 14.19% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
The bottom line: If you want the newer-generation Yukon XL with a more modern ride, more space, and strong owner approval, the 2021 is the better default choice. If your priority is stretching your budget as far as possible, a nearby older year may be worth considering, but you should expect to give up some of the 2021's updated feel and refinement.
