Compare the2025 Lexus GXVS 2025 GMC Yukon

For enhanced safety, the front and second-row seat shoulder belts of the Lexus GX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The GMC Yukon doesn’t offer pretensioners for its second-row seat belts.

The Lexus GX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Yukon doesn’t offer knee airbags.

The GX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Yukon doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, Full-Time Four-Wheel Drive is standard on the GX. But it costs extra on the Yukon.

Both the GX and the Yukon have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The GX comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Yukon’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

Lexus’ powertrain warranty covers the GX 1 year and 10,000 miles longer than GMC covers the Yukon. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Yukon ends after only 5 years or 60,000 miles.

The GX’s 6 year corrosion warranty has no mileage limitations, but the corrosion warranty on the Yukon runs out after 100,000 miles.

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

For better stopping power the GX’s standard front brake rotors are larger than those on the Yukon:

The GX stops shorter than the Yukon:

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

The GX Overtrail has active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Yukon doesn’t offer an active sway bar system.

The GX has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Yukon doesn’t offer variable-assist power steering.

The GX Premium handles at .72 G’s, while the Yukon AT4 pulls only .66 G’s of cornering force in a Motor Trend skidpad test.

The GX Premium executes Motor Trend’s “Figure Eight” maneuver 2.2 seconds quicker than the Yukon AT4 (28.4 seconds @ .61 average G’s vs. 30.6 seconds @ .51 average G’s).

For better maneuverability, the GX’s turning circle is .1 feet tighter than the Yukon’s (39.4 feet vs. 39.5 feet). The GX’s turning circle is 1.4 feet tighter than the Yukon Denali Ultimate w/24” wheels’ (39.4 feet vs. 40.8 feet).

For greater off-road capability the GX Premium has a 1.4 inches greater minimum ground clearance than the Yukon Denali Ultimate (8.7 vs. 7.3 inches), allowing the GX to travel over rougher terrain without being stopped or damaged.

The GX is 1 foot, 1 inches shorter than the Yukon, making the GX easier to handle, maneuver and park in tight spaces.

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

The GX’s rear cargo window opens separately from the rest of the liftgate door to allow quicker loading of small packages. The Yukon’s rear cargo window doesn’t open.

The GX’s standard towing capacity is much higher than the Yukon’s (9063 vs. 7500 pounds). Maximum trailer towing in the GMC Yukon is only 8200 pounds. The GX offers up to a 9096 lbs. towing capacity.

J.D. Power and Associates surveys of service recipients show that Lexus service is better than GMC. J.D. Power ranks Lexus first in service department satisfaction. With a 45% lower rating, GMC is ranked 20th.

The GX’s front and rear power windows all open or close 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 Yukon’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the GX the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the Yukon can only close 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 GX offers available headlight washers to keep headlight output high. The Yukon doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the GX offers optional cornering lights to illuminate around corners when the turn signals are activated. The Yukon doesn’t offer cornering lights.

Manual rear side window sunshades are available in the GX to help block heat and glare for the rear passengers. The Yukon doesn’t offer rear side window sunshades.
