Edmunds Expert Review of the 2015 GMC Yukon SUV

  • The 2015 GMC Yukon deserves strong consideration if you're shopping for a large, near-luxury truck-based SUV with impressive towing capacity. But for practical passenger and cargo use, a large crossover SUV might be a better choice.

  • Pros

    Strong V8 power; stout towing capacity; available nine-person seating capacity; extremely quiet highway ride; impressive interior quality.

  • Cons

    High cargo floor and load height; cramped kids-only third-row seat; no telescoping steering wheel for base model; lazy gas pedal responsiveness.

  • What's New for 2015

    The 2015 GMC Yukon is fully redesigned. Highlights include greater engine output with improved fuel economy, improved standard and optional equipment, an integrated fold-flat third-row seat, updated exterior styling, a quieter interior and low-range gearing now available on Denali model.

Love it, but it's not perfect

by on
Vehicle: 2015 GMC Yukon

Got my SLT April 2014. In the heat of summer, started having problems with AC. As time went by, the AC was taking longer and longer to cool. Took to dealership and was told there was no known defects and sent on my merry way without any action. Short time later, AC gave out completely. By the time I went the second time they finally did have instructions. Apparently it had too much freon, factory defect. Flushed and refilled freon. AC working fine now, but I still feel there's something wrong with it. When it's on full blast the vehicle shakes, almost like it wants to turn off, but RPM'S don't change and it stops when AC is off. Have taken it a couple of times and they insist it's normal. The platform in rear is a bummer, takes up too much space, very stupid idea. In spite of everything, I still love driving it, enjoy taking road trips.

Major problems

by on
Vehicle: 2015 GMC Yukon

Yukon is comfortable and exactly what I wanted. Tons of room, drives great, exactly like a $75,000 SUV should. But I have had constant issues since I purchased it. Most recent was the full replacement of the engine at 22,500 miles and 10 months of ownership. I've had seat issues, popping in steering wheel, loud wind noise coming from the sun roof. The 4 wheel drive system has had 3 issues and a recall since I owned it. The gauges stopped working, the steps get stuck. GM hasn't taken ownership that I have a lemon and this car needs to be bought back or replaced. I've owned 2 other Yukon Denali's and this has been the only one that I've ever had problems with.

New standards set for full-size luxury suvs

by on
Vehicle: 2015 GMC Yukon

The NEW, GM 2015 model Full-size SUVs indeed set new standards in this segment. I ordered out my Yukon Denali, which currently has about 8000 miles. I have had flawless performance and ZERO recalls or issues. The 6.2L/420HP V-8 is incredible. The fit and finish of this truck is amazing and the list of features is endless. The interior comfort and quietness at highway speed rivals any luxury sedan. I compared the new GM's against the other domestic and import brands in this market. Without any doubts, the structural integrity, interior materials, options and engines were were far superior in the GM lineup. As many predict, I agree that GM will continue to dominate the full-size SUV market!

Be cautious

by on
Vehicle: 2015 GMC Yukon

Almost all 2015 Yukons/Denalis with AWD are having severe problems with the transmission. Basically, if you used the AUTO setting on the drive selector the trans will lock into 4WD and never come out. GM has no fix for this problem yet. Driving the vehicle like this is unsafe and makes a horrible racket. It might also damage the vehicle. Avoid any Yukon or Tahoe until the fix is found. You can google this problem to read more about it

2015 slt

Vehicle: 2015 GMC Yukon

Have had a new Yukon SLT for about a week - hardest part was finding one - much better looking than the Chevy Tahoe. Truck has been great to date. Driving home from the dealer (35-miles) at 71-MPH on cruise, the unbroken in truck did 21.3 MPG with air on (has towing package). The only thing I miss is my magnetic ride from my Tahoe LTZ. Other than that, far superior comfortand features.

Pent-up demand

by on
Vehicle: 2015 GMC Yukon

A couple of years late, it's finally here. It was definitely worth waiting for - it's a totally different car than the previous model. I've had the car for 2-1/2 months now and have 5100 miles on it, most of them highway miles. 80 - 85 mph is no problem, and it feels like 60. Smoothest and quietest vehicle I've ever owned. Magnetic Ride Control, improved insulation and active sound management really do work in this one. Highway mileage is impressive even at high speed. Best is 25 mpg so far (over a 50 mile distance driving with the wind). With no wind mpg is around 20. In town mpg is about 14, but average city/hwy so far is 17.2 mpg. Factory Continental tires get high ratings.

What's New for 2015

The 2015 GMC Yukon is fully redesigned. Highlights include greater engine output with improved fuel economy, improved standard and optional equipment, an integrated fold-flat third-row seat, updated exterior styling, a quieter interior and low-range gearing now available on Denali model.


Car shoppers who are in the market for a traditional full-size SUV have only a handful of choices these days. But among this group, one of the most compelling is the 2015 GMC Yukon. It blends traditionally rugged truck construction and V8 towing capacity with amenities and features one might expect from a full-fledged luxury SUV.

Sandwiched between its corporate siblings, the Chevrolet Tahoe and pricier Cadillac Escalade, this year's fully redesigned Yukon shows off a new look inside and out. This GMC also boasts some innovative and improved features as well as a choice of two V8 powertrains that are both more powerful and fuel-efficient than those sold last year. As a result of these improvements, the Yukon is still a capable workhorse, but it rides down a highway or up a mountain pass more efficiently, comfortably, quietly and confidently than ever before.

For the first time in the Yukon, the third-row seat folds into the floor instead of having to be removed (a key convenience that most rivals adopted years ago). Power-actuated second- and third-row seating is a new option as well, allowing those of small stature to more easily manage what used to be a cumbersome operation. Unfortunately, they will also need to contend with a higher load floor.

Another notable upgrade is a new 8-inch touchscreen interface with added smartphone integration functionality. Finally, the most up-to-date electronic safety features find their way into the Yukon's roster, including lane-departure warning, a blind-spot monitor and frontal collision warning and mitigation.

Of course, if you don't really need the 2015 GMC Yukon's 4-ton towing capabilities, you might consider a more space-efficient crossover SUV. Top choices in this class routinely offer equal or greater people- and cargo-hauling abilities without the trucklike driving dynamics. In fact, there's an excellent one of those in GMC's own showroom: the eight-passenger Acadia, which offers substantially more third-row space and cargo capacity.

If a tow-ready traditional SUV is must, others to consider are the 2015 Toyota Sequoia, which presents a very similar mix of ruggedness and refinement, and the 2015 Ford Expedition, which received a mild makeover this year. Both are older designs, but offer more third row and cargo space. If you intend to discover your own secret fishing spot accessed only with four-wheel drive, the more prestigious (but smaller) 2015 Land Rover LR4 will get you there for about the same cost as a Yukon. Overall, though, the new GMC Yukon will handle most of the passenger and towing duties you can throw at it, and do so confidently, comfortably and safely.

Body Styles, Trim Levels, and Options

The 2015 GMC Yukon is a body-on-frame SUV available in three trim levels: SLE, SLT and Denali. Seating for eight is standard, but there are two optional seating arrangements: second-row captain's chairs drop the count to seven and an available 40/20/40 front bench seat increases it to nine. There is an extended-length version known as the Yukon XL covered in a separate review.

The base Yukon SLE comes standard with 18-inch alloy wheels, foglamps, a locking rear differential, front and rear parking sensors, heated power-adjustable manual-folding mirrors, automatic wipers, a tilt-only leather-wrapped steering wheel, tri-zone automatic climate control, premium cloth upholstery, power front seats (eight-way driver seat and four-way passenger seat, both with power lumbar), a 60/40 split-fold second-row bench seat and a 60/40-split fold-flat third-row seat. Also standard are remote engine start and entry, Bluetooth phone and audio connectivity and OnStar. For infotainment, an 8-inch touchscreen with the GMC IntelliLink interface (which includes voice control and smartphone app integration) is standard, as is a rearview camera. Audio is covered with a premium nine-speaker Bose sound system with HD and satellite radio, a CD player, five USB ports, an auxiliary audio jack and an SD card slot.

If you want nine-passenger capacity, you'll need to get the SLE, as the optional front bench seat is only available on this trim level. All Yukons are prepped for towing and feature a 2-inch receiver and seven-pin harness, but an HD Trailering package is also available on both SLE and SLT that includes specific gearing, a trailer-brake controller, an air suspension with increased capacity and leveling, and low-range gearing when combined with 4WD models.

For the Yukon SLE, a Driver Alert option includes forward collision alert, lane-departure warning and a vibrating safety alert seat. The SLE's Convenience package adds an auto-dimming rearview mirror, power-adjustable pedals and a power liftgate.

The SLT model includes the both the Driver Alert and Convenience packages and adds rear cross-traffic alert and blind-spot monitoring, power-folding mirrors (auto-dimming driver side), keyless ignition and entry, a power tilt-and-telescoping steering wheel, a heated steering wheel, driver memory settings, heated and ventilated front seats (10-way with four-way lumbar), heated second-row seats (power fold-and-tumble 60/40 bench), power folding third-row seats and ambient interior lighting.

Options include second-row captain's chairs (heated and power fold-and-tumble), an enhanced alarm system and adaptive cruise control with crash-imminent braking. A sunroof and a rear entertainment system with a Blu-ray player are either stand-alone options or, when combined with the optional navigation system, part of the Sun, Entertainment and Destination package.

To the SLT's standard features, the Yukon Denali adds a unique grille, a more powerful V8 engine, 20-inch alloy wheels, an adaptive magnetic suspension, a trailer-brake controller, xenon headlights, a reconfigurable digital instrument panel, a premium Bose 10-speaker surround-sound audio system, active noise cancellation, the navigation system and second-row captain's chairs (heated and power fold-and-tumble).

Optional for the Denali are power-retractable assist steps and a Touring package that adds the enhanced alarm system, the sunroof, chromed 20-inch wheels, the rear entertainment system and a head-up display. Also available are 22-inch wheels.

Powertrains and Performance

The GMC Yukon SLE and SLT come with a 5.3-liter V8 engine that generates 355 horsepower (up from last year's 320) and 383 pound-feet of torque. The 2015 GMC Yukon Denali is powered by a 6.2-liter V8 that produces 420 hp (up from 403 hp) and 460 lb-ft of torque.

For all Yukons, a six-speed automatic transmission transmits power to the rear wheels on 2WD models or all four wheels on 4WD models. The SLE and SLT's 4WD is a single-speed part-time system, but a two-speed transfer case with low-range gearing is optional (standard on the Denali 4WD).

Properly equipped, the maximum tow rating for the 2WD Yukon SLE or SLT is 8,500 pounds. 4WD and Denalis are a bit less.

In Edmunds testing, a 2015 Chevrolet Tahoe LTZ 4WD (nearly analogous to a Yukon SLT 4WD) hit 60 mph in 7.3 seconds -- a quick performance for a full-size 4WD SUV.

EPA-estimated fuel economy is expectedly low, but as full-size SUVs go, it's pretty respectable. Equipped with the 5.3-liter V8, the Yukon earns 18 mpg combined (16 city/23 highway with 2WD, and 22 highway with 4WD). The Denali's 6.2-liter V8 garners 17 mpg combined (15/21) in its 2WD edition, and 16 mpg combined (14/21) with 4WD.


Standard safety equipment on the 2015 GMC Yukon includes antilock disc brakes, traction control, stability control, front-seat side airbags and full-length side curtain airbags. An airbag located between the front bucket seats (when so equipped) aids in side-impact crashes. Also standard is OnStar, which includes automatic crash notification, on-demand roadside assistance, remote door unlocking, stolen vehicle assistance and turn-by-turn navigation. Front and rear parking sensors and a rearview camera are standard on every Yukon.

Depending on the trim level, a head-up display for the driver, forward collision alert, lane-departure warning, a vibrating safety alert seat, rear cross-traffic alert and blind-spot monitoring are either available or standard.

In Edmunds brake testing, a Tahoe LTZ 4WD (similar to a Yukon SLT) came to a stop from 60 mph in 126 feet, a short distance for a vehicle in this class.

In government crash tests, the Tahoe earned a four (out of five) star rating for overall performance, with five stars for total frontal-impact protection and five stars for side-impact protection.

Interior Design and Special Features

The overall quality and design of the 2015 GMC Yukon's interior is noticeably improved compared to those of the previous generations. Materials are of a high quality, and the gauge cluster's crisp graphics are a snap to read day or night. The large, central infotainment display is intuitive to navigate and its graphics/pictograms are simple and easily interpreted. Unfortunately, IntelliLink can sometimes be slow to respond to your touch inputs.

In terms of seating, the front seats are comfortable and reasonably supportive. The lack of a telescoping steering wheel on the SLE model will make it harder for some folks to get an ideal driving position, however. The available power-releasing second- and full-power up/down third-row seats work with ease. The third-row seat is fine for small children, but its low mounting to the floor means taller teenagers and adults will likely find their knees pushed up uncomfortably toward the roof. Most large crossovers offer more spacious third-row seating.

Given the very cumbersome nature of the previous-generation Yukon's third-row seat removal procedure (not to mention their attractiveness to "smash-and-grab" thieves), we're happy to see GM has finally integrated the third row firmly into the truck's floor. But the downside to those stow-away seats is the consequentially high (36 inches) cargo floor height, which makes it harder for shorter owners to load strollers or bigger shopping hauls.

Overall, cargo capacity is good but not great, as many crossovers (or the larger Yukon XL) fare better. With all seats occupied in the Yukon, there are only 15.3 cubic feet for luggage. Fold the rearmost seats down and there are 51.6 cubic feet. With the second and third rows down, maximum capacity stands at 94.7 cubes. Not only is this less room than its other large SUV rivals, it's significantly less volume than you'll get in a Chevrolet Traverse, which tops out at 116 cubic feet.

Driving Impressions

The 2015 GMC Yukon's 5.3-liter V8 engine is beefy enough to pull around a full complement of passengers and gear, yet plenty smooth and quiet. Due to the greater overall weight of the Yukon Denali and its larger engine -- and counter-intuitive as it may be -- to get the maximum Yukon tow rating you must select either the SLE or SLT with their smaller engines. Still, the more powerful V8 and thus more relaxed towing experience overall while behind the wheel of the Denali might be a more compelling reason to choose it over a couple hundred-pound difference when you're already tugging a heavy load or trailer.

We also like how the 2015 Yukon is luxury-car quiet, especially on the highway. The Denali's standard noise cancellation system is a further bonus. We're less fond of the Yukon's lazy responses from the gas pedal and transmission, though. There's a noticeable delay for acceleration while pressing on the gas pedal at highway speeds or from a stop.

Especially with the Denali's standard adaptive suspension, the 2015 Yukon feels relatively secure when going through turns and it soaks up irregular pavement with ease. We cannot recommend any of the fashionable 22-inch wheels, however, as their mass combined with their tires' lack of cushioning sidewalls adversely affects ride comfort. Also keep in mind that this is still a large and heavy truck-based vehicle, and large crossover SUVs will generally be easier to maneuver and more composed on rough pavement.
