For enhanced safety, the front and rear seat shoulder belts of the Lexus RX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Jeep Cherokee doesn’t offer pretensioners for its rear seat belts.
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 RX are reminded to check the back seat if they opened the rear door before starting out. The Cherokee doesn’t offer a back seat reminder.
The RX has a standard Secondary Collision Brake, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Cherokee doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The RX Premium/Luxury/500h F Sport offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Cherokee only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.
Both the RX and Cherokee have rear cross-traffic warning, but the RX offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The Cherokee’s Rear Cross-Path Detection doesn’t automatically brake.
The RX’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 Cherokee doesn’t offer a driver alert monitor.
Both the RX and the Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, 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, rear cross-path warning and available all wheel drive.
The Lexus RX achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Cherokee has not yet been evaluated by the IIHS for 2024.
