For enhanced safety, the front and middle seat shoulder belts of the Jeep Grand Cherokee L are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Subaru Ascent doesn’t offer height-adjustable middle seat belts.
The Jeep Grand Cherokee L 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 Ascent doesn’t offer a front passenger side knee airbag.
A passive infrared night vision system optional on the Grand Cherokee L 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 Ascent doesn’t offer a night vision system.
The Grand Cherokee L has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. Only the Ascent Premium/Onyx/Limited/Touring offers a blind spot warning system.
To help make backing out of a parking space safer, the Grand Cherokee L has standard Rear Cross Path Detection, helping the driver avoid collisions. Only the Ascent Premium/Onyx/Limited/Touring offers Rear Cross Traffic Alert.
Both the Grand Cherokee L and the Ascent 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, rearview cameras, available all wheel drive, around view monitors and driver alert 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 L is safer than the Ascent:
