Over 200 people are killed each year when backed over by motor vehicles. The Grand Cherokee has standard ParkSense Rear Park Assist with Stop that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Nautilus doesn’t offer backup collision prevention brakes.
A passive infrared night vision system optional on the Grand Cherokee Trailhawk/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 Nautilus doesn’t offer a night vision system.
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 Nautilus doesn’t offer a driver alert monitor.
Both the Grand Cherokee and the Nautilus have standard driver and passenger frontal airbags, front side-impact airbags, driver 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.
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 Nautilus:

For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, daytime pedestrian crash prevention, and nighttime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Grand Cherokee its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 36 vehicles tested by the IIHS. The Nautilus is only a standard “Top Safety Pick” for 2023.
