For enhanced safety, the front and second-row seat shoulder belts of the Lexus GX 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 Wrangler doesn’t offer pretensioners for its rear seat belts.
The GX’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Wrangler doesn’t offer pre-crash pretensioners.
For enhanced safety, the front and middle seat shoulder belts of the Lexus GX 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 Jeep Wrangler has only front height-adjustable 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 GX are reminded to check the back seat if they opened the rear door before starting out. The Wrangler doesn’t offer a back seat reminder.
The Lexus GX 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 Wrangler doesn’t offer knee airbags.
The GX has standard front and rear seat side-impact airbags and head airbags, which act as a forgiving barrier between the passengers and the door. Combined with high-strength steel door beams this system increases protection from broadside collisions. The Wrangler doesn't offer rear-seat side-impact airbags, only ones for front seat occupants.
The GX has standard Active Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Active Headrests system moves the headrests forward to prevent neck and spine injuries. The Wrangler doesn’t offer a whiplash protection system.
The GX has a standard Pre-Collision System, which uses forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The Wrangler offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
The GX’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. The Wrangler doesn’t offer a lane departure warning system.
The GX (except Base/Premium) offers an optional Panoramic View Monitor to allow the driver to see objects all around the vehicle on a screen. The Wrangler 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.
The GX has a standard blind spot warning system which 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 Wrangler’s blind spot costs extra.
To help make backing out of a parking space safer, the GX has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Only the Wrangler Sport S/Sahara/Rubicon offers a rear cross-path warning system and it costs extra.
The GX’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 Wrangler doesn’t offer a driver alert monitor.
Both the GX and the Wrangler have standard driver and passenger frontal airbags, front side-impact airbags, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and rearview cameras.
