When descending a steep, off-road slope, the Grand Cherokee Overland 4WD/Summit 4WD’s standard Hill-descent Control allows you to creep down safely. The QX55 doesn’t offer Hill-descent Control.
A passive infrared night vision system optional on the Grand Cherokee Overland/Summit 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 QX55 doesn’t offer a night vision system.
The Jeep Grand Cherokee’s optional 360-degree camera offers optional integrated front and rear camera washers, ensuring clear, all-weather visibility without the need for manual cleaning. In contrast, the Infiniti QX55 lacks camera washers, requiring you to manually clean the cameras for optimal performance.
The Grand Cherokee Summit’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 QX55 doesn’t offer a driver alert monitor.
Both the Grand Cherokee and the QX55 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Jeep Grand Cherokee is safer than the Infiniti QX55:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Jeep Grand Cherokee is safer than the QX55:
