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 Mazda CX-5 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 NX are reminded to check the back seat if they opened the rear door before starting out. The CX-5 doesn’t offer a back seat reminder.
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 CX-5 doesn’t offer knee airbags.
When descending a steep, off-road slope, the NX’s standard Downhill Assist Control allows you to creep down safely. The CX-5 doesn’t offer Downhill Assist Control.
Both the NX and CX-5 have rear cross-traffic warning, but the NX offers optional Parking Support Brake (automatically applies the brakes) to better prevent a collision when backing near traffic. The CX-5’s Rear Cross Traffic Alert doesn’t automatically brake.
Compared to metal, the NX’s plastic fuel tank can withstand harder, more intrusive impacts without leaking; this decreases the possibility of fire. The Mazda CX-5 has a metal gas tank.
Both the NX and the CX-5 have standard driver and passenger frontal airbags, front side-impact 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 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 CX-5 is only a standard “Top Safety Pick” for 2023.
