GMC Yukon Review: Is This Used Full-Size SUV Right for You?

Looking for a reliable used full-size SUV? The GMC Yukon is a strong candidate — it’s our pick in the large SUV category for the 10 best used cars in Canada. Below is a practical guide to help you evaluate a pre-owned Yukon.

The Yukon is a large, capable SUV designed for families who need space and towing ability. Its underpinnings are closely related to the GMC Sierra pickup, a proven and widely used platform, which contributes to the Yukon’s durability and towing prowess.

If you regularly tow trailers, travel long distances with a full load of passengers, or need four-wheel-drive capability for off-road use, the Yukon should be on your shortlist. Consider the Chevrolet Tahoe as well — it shares the same architecture and offers similar space for up to eight passengers plus cargo, gear and pets.

The 2021 redesign brought significant improvements: up to 66% more cargo volume behind the third row compared with earlier generations and a larger 10.2-inch centre touchscreen for a modern infotainment experience. That year also introduced the AT4 trim, which adds a tuned suspension and upgraded driveline for better composure and control across varied surfaces.

Model-year 2022 expanded choices across the Yukon and Tahoe ranges, increasing the availability of higher-performance engines, upgraded connectivity and additional safety technology — features that add value when shopping used.

General Motors has enjoyed strong customer loyalty in recent years, and models like the Yukon and Tahoe are a meaningful part of that reputation. Their mix of capability, comfort and a well-tested platform make them practical options for many buyers.

Is the GMC Yukon a good car?

The Yukon blends the passenger space of a minivan with the hauling capability of a truck. It can tow, haul and transport large families comfortably, making it a very versatile vehicle.

Most used Yukons come with one of two V8 gasoline engines: a more economical 5.3-litre or a more powerful 6.2-litre. Both engines employ stop/start systems and Dynamic Fuel Management, which can deactivate cylinders when full power isn’t needed to improve fuel economy.

From 2021, an optional 3.0-litre Duramax inline-six turbodiesel became available. It delivers high torque and improved fuel efficiency on highways, offering a compelling balance between towing performance and economy.

These powertrains are well-proven and equipped with modern fuel-saving technologies. Whether you prioritize hauling ability or better fuel economy, the Yukon’s options provide flexibility to match different needs.

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

When testing a Yukon, pay attention to how it rides and handles. The AT4 trim includes a specialized suspension and rear axle that improve comfort and composure on rough roads and in winter conditions, provided you fit proper winter tires. Popular winter options among owners include models from Michelin and Nokian, which improve traction and stability in snow and ice.

The Duramax diesel is worth special consideration. While its 277 horsepower may sound modest for a vehicle this size, its 460 lb-ft of torque matches the output of the thirsty 6.2-litre V8 and is available at low rpm, which makes towing and heavy-load driving feel effortless. The diesel is also quieter and smoother than many expect, though it won’t offer the V8’s distinctive engine note.

For buyers seeking a luxury-oriented experience, the Yukon Denali delivers upscale materials and features while still feeling rugged and confident. The Denali trim often provides a more refined cabin without the pretension of some luxury competitors.

The Yukon also picked up industry recognition: the 2021 model earned awards for Best Large SUV and SUV of the Year in various publications, and it has been noted for strong resale value among full-size SUVs.

Before you buy a used GMC Yukon

Because the current-generation Yukon launched in 2021, you can often find recent, lower-mileage examples that still carry factory warranty coverage. Before buying, understand the ongoing costs associated with a large SUV: maintenance, replacement tires, winter tires, fuel and insurance. Vehicles that last longest are usually the best-maintained, so review service records and confirm maintenance history with the seller or dealership.

Warranty coverage on a used Yukon may require proof of proper maintenance; aftermarket parts or neglected service can affect coverage. Be sure to verify what remains of any transferable warranty and that all scheduled services were completed.

Check wheel and tire sizes as well. Higher trims commonly use wheels of 20 inches or larger; while they look sharp, larger wheels can reduce ride comfort on rough surfaces. If you drive frequently on uneven or unpaved roads, a model with smaller wheels and thicker tires will usually deliver a more comfortable ride.

GMC Yukon issues to know about

Buyers should understand where the Yukon’s strengths lie. Its real value is in the chassis, platform and powertrain rather than an opulent cabin. Some owners would like richer interior materials and more varied color choices. Others point out the large footprint, high price in upper trims, and the unconventional pull-switch shifter as minor drawbacks, particularly in tight parking or urban environments.

Should I buy a GMC Yukon?

The Yukon is an excellent choice if you need a comfortable, spacious SUV that can tow and carry large families with ease. If towing and cabin space are priorities and you want durability and dependability, the Yukon fits well — and the Duramax diesel is a notable option for drivers seeking torque and better long-haul fuel economy.

If you live in an area with severe winters or regularly drive on rough roads, consider the AT4 for its off-road-oriented suspension and driveline features that make winter and rough-road driving more manageable.
