CarGurus Analysis: 2021 GMC Yukon XL
Summary
With 1,588 currently listed for sale and an average price of $39,224, 34.1% 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.
72.8% 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 puts space and comfort first without giving up a premium feel. For 2021, it debuted with a new 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 also adds more than a foot between the front and rear axles, which translates into extra room for passengers and luggage. Owners echo that appeal, often praising the Yukon XL’s spacious interior, luxury feel, and comfort on long trips.
It also offers a wide range of equipment and powertrains, which makes it flexible for different kinds of buyers. The standard engine is a 5.3L V8, with a 6.2L V8 and a 3.0L Duramax turbo-diesel available, all paired with a 10-speed automatic transmission. The 2021 model’s standard features include 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 add features such as heated and ventilated front seats, leather seating surfaces, a power liftgate, four-wheel drive, a head-up display, and a 14-speaker Bose audio system. For buyers who want a large SUV that feels upscale and can be configured for family duty, towing, or off-road use, the 2021 Yukon XL has a lot going for it.
There are tradeoffs, though. The buying guide notes that the Yukon XL has poor fuel economy and poor handling compared to car-based crossovers, and some owners want better brakes. Even so, the 2021 model’s combination of space, comfort, and available luxury equipment makes it distinctive among large SUVs.

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 | $39,200 |
| Year-Round Low | $39,200 |
| Year-Round High | $46,011 |
| Average Price a Year Ago | $45,999 |
| Change vs. Last Year | −14.78% |
Prices have softened 14.78% compared to this time last year, making it a favorable time to shop this model year.
There are 1,585 listings available, which gives you a solid amount of inventory to compare before you buy.
Is the 2021 GMC Yukon XL a good car?
Yes — owners rate it 5/5, which is a strong signal that it delivers on what shoppers want in a large SUV. The review summary repeatedly points to its luxury feel, spacious interior, and comfort on long trips, and it also highlights the powerful engine and surprising agility for something this size. That lines up well with its role as a full-size SUV built for family duty, towing, and long-distance comfort. With 35.6% of listings marked as good or great deals, you have a decent chance of finding a value-oriented example.
Is the 2021 GMC Yukon XL reliable?
Owners rate it 5/5, a strong signal of long-term satisfaction.
The review summary also emphasizes that owners see it as dependable and trouble-free enough to trust for long trips, with many feeling confident in its long-term ownership experience. The main caution for used buyers is that a large, complex SUV can become expensive if prior maintenance was skipped, so condition and service history matter a lot.
What should I look for when buying a used 2021 GMC Yukon XL?
At 72.7% 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 reported damage was repaired properly. Then prioritize a pre-purchase inspection, especially for brakes, suspension, and any signs of uneven wear or poor repair work. Because this is a large SUV, you should also focus on how it drives under braking, at highway speeds, and with a full load of passengers or cargo.
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 patiently but still move quickly when a strong listing appears.
- Deal availability: 35.6% of listings are priced as good or great deals.
- Inventory: There are 1,585 listings available.
- Price trend: Prices have softened 14.78% compared with last year.
- Clean inventory: 72.7% of listings are accident-free.
If you find a listing below $39,200, 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 $39,200 sits slightly below last year's $45,999.
That drop suggests the market has already adjusted downward, which can help you buy at a more favorable entry point today. For a future seller, that also means resale value will depend heavily on how well your vehicle is maintained, how clean its history is, and whether it stands out with desirable equipment and condition. Strong presentation matters more when the broader market has softened.
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:
- 35.6% of listings are priced as good or great deals.
- At 72.7% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
- Price trend: Prices have softened 14.78% compared with last year.
- Owners rate it 5/5 — a strong satisfaction signal.
The bottom line: You should lean toward the 2021 if you want the newer redesign, the added space from the independent rear suspension, and a strong owner satisfaction signal. If your main goal is to spend less, a nearby older year may be worth considering, but you’ll want to balance that against the 2021’s improved packaging and comfort.
