Used 2019 GMC Yukon XL SLT SUV Review

Nine-passenger capacity combined with strong towing power is hard to come by, and it's what makes the 2019 GMC Yukon XL a great choice for big families with big toys. Aside from a few other truck-based large SUVs, there isn't anything else available that can match the Yukon XL's skill set. The trade-off is that the Yukon's imposing mass and traditional SUV design compromise maneuverability, fuel economy and ride comfort.

But you expect as much in an SUV of this size, and the Yukon XL's utility is undeniable. Even with the third-row seats deployed, it has 39.3 cubic feet of cargo space available. Fold down the second and third rows, and you've got a whopping 121.7 cubic feet of maximum cargo space at your disposal. If towing is your thing, the Yukon XL can lug up to 8,300 pounds.

All of this makes the Yukon XL a fairly mission-specific vehicle. Sure, for a big SUV, we've found it easy to drive, as long as you're going straight. But there's no escaping the Yukon XL's roots. Navigating tight parking lots and city streets requires caution, calculation, and some amount of faith in the space around the vehicle. The truck-based suspension can't deliver the carlike ride comfort of a crossover, nor is the Yukon a picture of fuel efficiency.

You might want to check out the Ford Expedition Max. It has just as much capability as the Yukon, if not more, but is a more refined and upscale vehicle overall. But overall the Yukon XL's size, power and style will undoubtedly hit the mark for a very specific buyer.

The 2019 GMC Yukon XL is a full-size SUV offered in SLE, SLT and Denali trim levels. The smaller Yukon is covered in a separate review. Most Yukon XLs seat eight passengers, but an optional front bench seat on the SLE trim increases the capacity to nine. Second-row bucket seats are available on the SLT trim and standard on the Denali; they reduce passenger capacity to seven.

The SLE base trim starts with a 5.3-liter V8 engine (355 horsepower, 383 lb-ft of torque) paired to a six-speed automatic transmission. Rear-wheel drive is standard, and four-wheel drive is optional.

Standard SLE features include 18-inch alloy wheels, foglights, side steps, roof rails, front and rear parking sensors, automatic wipers, and a trailer hitch receiver with a wiring harness. Standard interior features include tri-zone automatic climate control, power-adjustable front seats, and 60/40-split folding second- and third-row seats.

Also included is a 110-volt power outlet, an 8-inch touchscreen interface, a rearview camera, Bluetooth, OnStar communications (with a 4G LTE connection and Wi-Fi hotspot), Apple CarPlay and Android Auto, and a nine-speaker Bose audio system with CD player, satellite and HD radio and five USB inputs.

The optional Enhanced Driver Alert package adds forward collision warning with automatic low-speed emergency braking, a vibrating safety-alert driver's seat, automatic high beams, and lane departure warning and intervention. The Convenience package adds a power-operated liftgate, an auto-dimming rearview mirror, power-adjustable pedals and a universal garage door opener.

The SLT trim is broken down into SLT Standard Edition and SLT subtrims. The Standard Edition includes all of the above, along with leather upholstery, heated front seats, a power-adjustable front passenger seat and driver-seat memory functions. The SLT further gets you hands-free operation for the rear liftgate, blind-spot monitoring with rear cross-traffic alert, keyless entry and ignition, a heated and power tilt-and-telescoping steering wheel, ventilated front seats, heated second-row seats, and power-folding second- and third-row seats.

For 2019, the SLT also gets two new packages. The optional Graphite Edition package for SLT includes 22-inch wheels and blacked-out exterior trim (side steps, grille), while the Graphite Performance Edition boosts performance and comfort with a 6.2-liter V8 engine (420 hp, 460 lb-ft of torque), a 10-speed transmission, a heavy-duty alternator, Magnetic Ride Control adaptive dampers, a head-up display, a customizable gauge cluster, active noise cancellation system, and upgraded cabin air filtration.

The top-of-the-line Denali trim builds on the features listed above, including those from the Graphite Performance Edition, and adds 20-inch wheels, a two-speed transfer case (4WD models), xenon headlights, a trailer brake controller, power-folding second-row bucket seats, a navigation system, a wireless smartphone charging pad and a 10-speaker Bose surround-sound system.

The optional Denali Ultimate package bundles 22-inch wheels, a sunroof, power side steps, adaptive cruise control, a rear seat entertainment system with DVD player, and an extended satellite radio and traffic information subscription, among other items.

Several Denali features are offered as options on SLT trims, while options for SLE and SLT trims include 22-inch wheels, navigation, and a heavy-duty trailering package with a unique axle ratio, trailer brake controller and a self-leveling suspension.
