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 GMC Terrain doesn’t offer pretensioners for the rear seat belts.
For enhanced safety, the front seat shoulder belts of the Lexus NX 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 GMC Terrain doesn’t offer height-adjustable front 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 Terrain doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The NX offers optional Intuitive Parking Assist with Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Terrain doesn’t offer backup collision prevention brakes.
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. A system to reveal vehicles in the Terrain’s blind spot costs extra.
To help make backing out of a parking space safer, the NX 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. Rear cross-path warning costs extra on the Terrain.
The NX’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 Terrain doesn’t offer a driver alert monitor.
Both the NX and the Terrain have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available around view monitors.
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, with its optional vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the NX its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 80 vehicles tested by the IIHS. The Terrain last would have qualified as only a standard “Top Safety Pick” in 2017.
