For enhanced safety, the front and rear seat shoulder belts of the Lexus UX 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 Nissan Kicks doesn’t offer pretensioners for its rear seat belts.
Using vehicle speed sensors and seat sensors, smart airbags in the UX deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The UX’s side airbags will shut off if a child is leaning against the door. The Kicks’ side airbags don’t have smart features and will always deploy full force.
The UX has standard Whiplash Injury Lessening Front Seatbacks, which use a specially designed seat to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Injury Lessening Front Seatbacks system allows the backrest to travel backwards to cushion the occupants and the headrests move forward to prevent neck and spine injuries. The Kicks doesn’t offer a whiplash protection system.
The UX 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 Kicks 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 UX offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Kicks doesn’t offer all-wheel drive.
Both the UX and the Kicks have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available rear parking sensors.
The Lexus UX weighs 732 to 920 pounds more than the Nissan Kicks. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts. Crosswinds also affect lighter cars more.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Lexus UX is safer than the Nissan Kicks:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the UX is 1.5% less likely to roll over than the Kicks.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the UX the rating of “Top Safety Pick” for 2022, a rating granted to only 162 vehicles tested by the IIHS. The Kicks last would have qualified as a “Top Safety Pick” in 2019.
