In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Grand Cherokee are reminded to check the back seat if they opened the rear door before starting out. The Model Y doesn’t offer a back seat reminder.
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 Model Y 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 Model Y doesn’t offer a night vision system.
The Grand Cherokee (except Laredo) offers an optional 360-degree camera to allow the driver to see objects all around the vehicle on a screen. The Model Y only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
To help make backing out of a parking space safer, the Grand Cherokee’s standard Rear Cross Path Detection uses sensors in the rear to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Model Y doesn’t offer a rear cross-path warning 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 Model Y doesn’t offer a driver alert monitor.
The Grand Cherokee (except Laredo) offers optional Uconnect Access, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Model Y doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Grand Cherokee and the Model Y 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, 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 and available all wheel drive.
