For enhanced safety, the front and rear seat shoulder belts of the Lexus NX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The Kia Sportage doesn’t offer pretensioners for its rear seat belts.
The Lexus NX 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 Sportage doesn’t offer knee airbags.
The NX 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. Only the Sportage EX/SX/Prestige/X-Line/X-Pro offers a blind spot warning system.
To help make backing out of a parking space safer, the NX has standard Rear Cross-Traffic Alert to warn the driver of approaching traffic and automatically engage the brakes to help avoid a collision. Only the Sportage EX/SX/Prestige/X-Line/X-Pro offers Rear Cross-Traffic Collision Warning.
Both the NX and the Sportage have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, 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, rearview cameras, driver alert monitors and available 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 NX its highest rating: “Top Safety Pick Plus” for 2023, a rating granted to only 30 vehicles tested by the IIHS. The Sportage last would have qualified as only a standard “Top Safety Pick” for 2019.
