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 Blazer doesn’t offer backup collision prevention brakes.
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 Blazer doesn’t offer Hill-descent Control.
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 Blazer doesn’t offer a night vision system.
The Grand Cherokee 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. A system to reveal vehicles in the Blazer’s blind spot costs extra.
To help make backing out of a parking space safer, the Grand Cherokee has standard Rear Cross Path Detection, helping the driver avoid collisions. Chevrolet charges extra for Rear Cross Traffic Alert on the Blazer.
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 Blazer doesn’t offer a driver alert monitor.
Both the Grand Cherokee and the Blazer 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 and around view monitors.
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 Blazer has not been fully tested, yet.
