2018 GMC Yukon XL Overview

By Cars.com Editors
Vehicle Overview

What it is: The Yukon is a full-size, truck-based SUV that can seat up to nine people in certain configurations. The Yukon shares its platform with the Chevrolet Tahoe and Suburban, and it comes in two sizes: regular and XL, the latter being GMC's version of the Suburban

Both the Yukon and the Yukon XL are available with rear- or four-wheel drive, and competitors include the Ford Expedition, Nissan Armada and Toyota Sequoia.

New for 2018

Denali models get a new chrome grille, plus a 10-speed automatic transmission that replaces an eight-speed automatic.

Yukon XL

Whereas the regular Yukon is a twin to the Chevrolet Tahoe full-size SUV, the Yukon XL is GMC's version of the Chevrolet Suburban — a king-size SUV. The Yukon XL has the same styling and major features of the regular Yukon but offers more cargo room.

What's Special

  • Wheelbase is 14 inches longer than Yukon's
  • Overall length is 20.4 inches longer
  • Maximum cargo volume is 26.4 cubic feet greater, at 121.1 cubic feet

Best car I've ever owned

by baughkm from las vegas, nv on October 15, 2018

I love this car. DON'T buy at Earnhardt GMC though. They were terrible. But yes, buy this car if you want a large and very automated SUV. Read full review

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
