Both the Yukon XL and QX80 have child safety locks to prevent children from opening the rear doors. The Yukon XL 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 QX80’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.
When descending a steep, off-road slope, the Yukon XL 4WD’s optional Hill Descent Control allows you to creep down safely. The QX80 doesn’t offer Hill Descent Control.
A passive infrared night vision system optional on the Yukon XL Ultimate helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The QX80 doesn’t offer a night vision system.
Both the Yukon XL and QX80 have Rear Cross Traffic Alert, but the Yukon XL has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX80’s Rear Cross Traffic Alert doesn’t automatically brake.
Both the Yukon XL and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, 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, around view monitors, rear cross-path warning, available all wheel drive and driver alert monitors.
