Safety

Both the Yukon and Sequoia have child safety locks to prevent children from opening the rear doors. The Yukon has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Sequoia’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Yukon are reminded to check the back seat if they opened the rear door before starting out. The Sequoia doesn’t offer a back seat reminder.

The Yukon has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Sequoia doesn’t offer front seat center airbags.

Full-time four-wheel drive is optional on the Yukon. Full-time four-wheel drive gives added traction for safety in all conditions, not just off-road, like the only system available on the Sequoia.

The Yukon has standard OnStar®, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Sequoia doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Yukon and the Sequoia 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, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

Warranty

The Yukon’s corrosion warranty is 1 year longer than the Sequoia’s (6 vs. 5 years).

There are over 38 percent more GMC dealers than there are Toyota dealers, which makes it easier should you ever need service under the Yukon’s warranty.

Reliability

The Yukon has a standard “limp home system” to keep drivers from being stranded if most or all of the engine’s coolant is lost. The engine will run on only half of its cylinders at a time, reduce its power and light a warning lamp on the dashboard so the driver can get to a service station for repairs. The Sequoia doesn’t offer a lost coolant limp home mode, so a coolant leak could strand you or seriously damage the truck’s engine.

To reliably start during all conditions and help handle large electrical loads, the Yukon has a standard 720-amp battery. The Sequoia’s 710-amp battery isn’t as powerful.

J.D. Power and Associates rated the Yukon second among large suvs in their 2018 Initial Quality Study. The Sequoia isn’t in the top three.

Engine

The Yukon Graphite Performance Edition/Denali’s standard 6.2 V8 produces 39 more horsepower (420 vs. 381) and 59 lbs.-ft. more torque (460 vs. 401) than the Sequoia’s 5.7 DOHC V8.

An engine control system that can shut down half of the engine’s cylinders helps improve the Yukon’s fuel efficiency. The Sequoia doesn’t offer a system that can shut down part of the engine.

The Yukon has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Sequoia doesn’t offer a cap-less fueling system.

Transmission

A ten-speed automatic is standard on the GMC Yukon Graphite Performance Edition/Denali, for better acceleration and lower engine speed on the highway. Only a six-speed automatic is available for the Sequoia.

Brakes and Stopping

The Yukon stops much shorter than the Sequoia:

Tires and Wheels

For better traction, the Yukon’s optional tires are larger than the largest tires available on the Sequoia (285/45R22 vs. 275/65R18).

The Yukon’s optional tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Sequoia TRD Sport/Limited/Platinum’s 55 series tires.

For better ride, handling and brake cooling the Yukon offers optional 22-inch wheels. The Sequoia’s largest wheels are only 20-inches.

The GMC Yukon’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Toyota Sequoia only has 5 wheel lugs per wheel.

The Yukon has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Sequoia doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

The Yukon SLT 4x4 handles at .78 G’s, while the Sequoia Limited 4x4 pulls only .72 G’s of cornering force in a Motor Trend skidpad test.

The Yukon SLT 4x4 executes Motor Trend’s “Figure Eight” maneuver 2.3 seconds quicker than the Sequoia Limited 4x4 (27.5 seconds @ .65 average G’s vs. 29.8 seconds @ .55 average G’s).

Chassis

The GMC Yukon may be more efficient, handle and accelerate better because it weighs about 250 to 350 pounds less than the Toyota Sequoia.

The front grille of the Yukon uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Sequoia doesn’t offer active grille shutters.

The Yukon Graphite Performance Edition//Denali uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The Sequoia doesn’t offer active noise cancellation.

Passenger Space

The Yukon offers optional seating for 9 passengers; the Sequoia can only carry 8.

The Yukon has 8 inches more front headroom, 2.8 inches more front legroom, 3.8 inches more rear headroom, .4 inches more rear hip room and 3.6 inches more third row headroom than the Sequoia.

Cargo Capacity

Pressing a switch automatically lowers the Yukon SLT/Denali’s second and third row seats, to make changing between passengers and cargo easier. The Sequoia doesn’t offer automatic folding second row seats.

To make loading groceries and cargo easier when your hands are full, the Yukon SLT/Denali’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Sequoia doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Payload and Towing

Maximum trailer towing in the Toyota Sequoia is limited to 7400 pounds. The Yukon offers up to a 8500 lbs. towing capacity.

The Yukon has a much higher standard payload capacity than the Sequoia (1650 vs. 1250 lbs.).

The Yukon has a much higher maximum payload capacity than the Sequoia (1690 vs. 1350 lbs.).

Ergonomics

The engine computer on the Yukon automatically engages the starter until the car starts with one twist of the key and disables the starter while the engine is running. The Sequoia’s starter can be accidentally engaged while the engine is running, making a grinding noise and possibly damaging the starter and ring gear.

The Yukon Graphite Performance Edition/Denali has a standard heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Sequoia doesn’t offer a heads-up display.

The power windows standard on both the Yukon and the Sequoia have locks to prevent small children from operating them. When the lock on the Yukon is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The Sequoia prevents the driver from operating the other windows just as it does the other passengers.

The Yukon’s front and rear power windows all lower with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Sequoia’s rear power window switches have to be held the entire time to open them fully.

Keyless Access standard on the Yukon SLT/Denali allows you to unlock the doors, cargo door and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Toyota Sequoia doesn’t offer an advanced key system.

The Yukon’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Sequoia’s manually variable intermittent wipers have to be constantly adjusted.

The Yukon’s power mirror controls are mounted on the armrest for easy access. The Sequoia’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.

On extremely cold winter days, the Yukon SLT/Denali’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Sequoia doesn’t offer a heated steering wheel.

Economic Advantages

Insurance will cost less for the Yukon owner. The Complete Car Cost Guide estimates that insurance for the Yukon will cost $35 to $670 less than the Sequoia over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the GMC Yukon will be $1615 to $5099 less than for the Toyota Sequoia.

Recommendations

J.D. Power and Associates rated the Yukon second among large suvs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Sequoia isn’t in the top three.

The GMC Yukon/Yukon XL outsold the Toyota Sequoia by over seven to one during 2018.
