Safety

The Sequoia’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Yukon doesn’t offer a driver alert monitor.

Both the Sequoia and the Yukon have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras and available four-wheel drive.

Warranty

The Sequoia’s corrosion warranty is unlimited miles longer than the Yukon’s (unlimited vs. 100,000 miles).

Toyota pays for scheduled maintenance on the Sequoia for 2 years and 25000 miles. Toyota will pay for oil changes, lubrication and any other required maintenance. GMC only pays for the first scheduled maintenance visit on the Yukon.

Reliability

For smoother operation, better efficiency and fewer moving parts, the Sequoia has an overhead cam design, rather than the old pushrod design of the engines in the Yukon.

To reliably power the ignition and other systems and to recharge the battery, the Sequoia has a standard 180-amp alternator. The Yukon’s standard 150-amp alternator and largest (6.2 V8) 170-amp alternator aren’t as powerful.

J.D. Power and Associates rated the Sequoia second among large suvs in their 2019 Initial Quality Study. The Yukon isn’t in the top three.

J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Toyota vehicles are more reliable than GMC vehicles. J.D. Power ranks Toyota second in reliability, above the industry average. With 53 more problems per 100 vehicles, GMC is ranked 22nd.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Toyota vehicles are more reliable than GMC vehicles. Consumer Reports ranks Toyota second in reliability. GMC is ranked 25th.

Engine

The Sequoia’s 5.7 DOHC V8 produces 26 more horsepower (381 vs. 355) and 18 lbs.-ft. more torque (401 vs. 383) than the Yukon’s standard 5.3 V8.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Toyota Sequoia uses regular unleaded gasoline. The Yukon Graphite Performance Edition/Denali requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Toyota Sequoia higher (5 out of 10) than the GMC Yukon (3). This means the Sequoia produces up to 16.5 pounds less smog-producing pollutants than the Yukon every 15,000 miles.

Motor Trend

Tires and Wheels

For better traction, the Sequoia has larger tires than the Yukon (275/65R18 vs. 265/65R18).

Suspension and Handling

For superior ride and handling, the Toyota Sequoia has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The GMC Yukon has a solid rear axle, with a non-independent rear suspension.

The Sequoia has standard front and rear stabilizer bars, which help keep the Sequoia flat and controlled during cornering. The Yukon’s suspension doesn’t offer a rear stabilizer bar.

For a smoother ride and more stable handling, the Sequoia’s wheelbase is 6 inches longer than on the Yukon (122 inches vs. 116 inches).

The Sequoia’s front to rear weight distribution is more even (50.4% to 49.6%) than the Yukon’s (52% to 48%). This gives the Sequoia more stable handling and braking.

The Sequoia TRD Sport 4x4 handles at .78 G’s, while the Yukon SLT pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

The Sequoia TRD Sport 4x4 executes Motor Trend’s “Figure Eight” maneuver quicker than the Yukon SLT (27.3 seconds @ .65 average G’s vs. 28 seconds @ .62 average G’s).

For better maneuverability, the Sequoia’s turning circle is .9 feet tighter than the Yukon’s (38.1 feet vs. 39 feet).

For greater off-road capability the Sequoia Platinum has a 1.6 inches greater minimum ground clearance than the Yukon (9.6 vs. 8 inches), allowing the Sequoia to travel over rougher terrain without being stopped or damaged. The Sequoia’s minimum ground clearance is 2 inches higher than on the Yukon (10 vs. 8 inches).

Passenger Space

The Sequoia has 1.7 inches more front hip room, 1.6 inches more front shoulder room, 1.9 inches more rear legroom, .5 inches more rear shoulder room, 10.5 inches more third row legroom, 1.1 inches more third row hip room and 3.1 inches more third row shoulder room than the Yukon.

For enhanced passenger comfort on long trips the Sequoia’s middle and third row seats recline. The Yukon’s third row seats don’t recline.

The front step up height for the Sequoia is 1.4 inches lower than the Yukon (21” vs. 22.4”). The Sequoia’s rear step up height is .2 inches lower than the Yukon’s (22.2” vs. 22.4”).

A low lift-over cargo hatch design makes loading and unloading the Sequoia easier. The Sequoia’s cargo hatch lift-over height is 33 inches, while the Yukon’s liftover is 35.9 inches.

Towing

The Sequoia’s minimum standard towing capacity is much higher than the Yukon’s (7100 vs. 6300 pounds).

Ergonomics

If the front windows are left open on the Sequoia the driver can close them at the outside door handle. On a hot day the driver can also lower the windows the same way. The driver of the Yukon can only operate the windows from inside the vehicle, with the ignition on.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Sequoia has standard headlight washers to keep headlight output high. The Yukon doesn’t offer headlight washers.

Economic Advantages

According to The Car Book by Jack Gillis, the Sequoia is less expensive to operate than the Yukon because it costs $464 less to do the manufacturer’s suggested maintenance for 50,000 miles. Typical repairs cost much less on the Sequoia than the Yukon, including $59 less for a water pump, $774 less for a muffler, $16 less for front brake pads, $64 less for fuel injection and $370 less for a power steering pump.
