GMC Yukon review: The best used large SUV

What to look for when test-driving a used GMC Yukon

What else should you look for when shopping for a used Yukon? The AT4 trim grade features a high-tech suspension and rear axle that makes the drive simultaneously more comfortable and agile, and you should see it soak up bumpy roads and tear through icy, snowy conditions with a proper set of winter rubber installed. (My personal favourites are the Michelin X-Ice and Nokian Hakkapeliitta.)

Then, there’s the straight-six turbo diesel engine, dubbed Duramax, which provides the torque of a 6.2-litre V8 but turns in the fuel economy of a much less potent V6 crossover.

When GM announced it would bring the same Duramax diesel engines it employs in its pickup trucks over to its full-size SUVs, including the luxurious GMC Yukon Denali, shoppers got excited.

Although 277 horsepower seems low for a vehicle of the Yukon’s considerable size and weight, torque is the all-important number when it comes to moving a heavy object, and this 3-litre straight-six delivers plenty of it, with 460 lb-ft. That matches the output of the (much thirstier) 6.2-litre V8, but makes the bulk of that torque available right out of idle. Though it can’t match the V8 engines when it comes to the soundtrack, the Duramax is smoother and quieter than most test-driving shoppers will expect. 

If you’re after an upscale SUV experience, opt for a Yukon Denali. This popular trim grade comes dressed up and decked out for a luxurious feel, yet it lacks the snootiness of many competitors, most of which can’t match the Yukon’s reputation for inspiring confidence via its tough and proven platform. The GMC Yukon has earned industry recognition, too. The 2021 model stuffed its trophy rack with impressive hardware: an InMoment eNVy Award for Best Large SUV, Four Wheeler’s SUV of the Year award, and Kelley Blue Book’s Best Resale Value award for a full-size SUV.

Before you buy a used GMC Yukon

The latest-generation GMC Yukon was all new for model year 2021, meaning it should be easy to find a lower-mileage unit with plenty of remaining warranty, if your budget allows.

If this is your first foray into the world of owning a large SUV, be sure to fully understand the cost of its maintenance requirements, replacement tires, winter tires, fuel and insurance before making a decision. The longest-lasting SUVs on the road tend to be the ones that are the best-maintained.

Have a look at all service records before you buy, or make sure they’re accessible to the selling dealership. In the unlikely event that you need a warranty-related repair, you may need to prove that all maintenance and servicing is up to date. Remember, the used Yukon’s remaining warranty doesn’t cover damage or wear caused by non-factory parts or fluids, or a failure to maintain the vehicle properly.

Take note of tire and wheel sizing before you buy, too. High-grade models will roll on larger-diameter wheels, pushing up to and beyond 20 inches. Though bigger wheels look fantastic, they may diminish ride quality on rough surfaces and are typically best for drivers spending most of their time on the highway. If you’ll do a lot of off-road or backroads driving on rougher surfaces, you’ll likely find a model with smaller wheels (and thicker tires) to deliver a more comfortable ride there.

GMC Yukon issues to know about

Your investment in a GMC Yukon goes more towards its platform, chassis and powertrain than its interior. Though owners appreciate the confident and capable drive, many long for a more upscale cabin with richer materials and colours. If you’re after the most striking or high-quality interior for the dollar, this isn’t the machine you’re after.

Other owners and reviewers have mixed feelings about the pull-switch shifter, very expensive pricing and enormous size, which can make parking and navigating in tighter quarters more difficult.

Should I buy a GMC Yukon?

You have other interesting options when shopping for a large used SUV, but if you require a vehicle that can hold your entire family and their gear in luxurious comfort while towing your boat around, the Yukon might be exactly what you need—just remember to ask about that wonderful Duramax diesel.
