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 Terrain are reminded to check the back seat if they opened the rear door before starting out. The Trax doesn’t offer a back seat reminder.
The Terrain has standard Automatic Emergency Braking, which use 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 Trax doesn't offer collision warning or crash mitigation brakes.
When descending a steep, off-road slope, the Terrain’s standard Hill Descent Control allows you to creep down safely. The Trax doesn’t offer Hill Descent Control.
The Terrain’s lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The Trax doesn’t offer a lane departure warning system.
The Terrain SLT/AT4/Denali offers an optional Surround Vision to allow the driver to see objects all around the vehicle on a screen. The Trax 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.
Both the Terrain and the Trax have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, blind spot warning systems and rear cross-path warning.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Terrain is 1.3% to 1.5% less likely to roll over than the Trax.
For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the Terrain the rating of “Top Safety Pick” for 2017, a rating granted to only 231 vehicles tested by the IIHS. The Trax has not been fully tested, yet.
