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 Encore 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 Encore offers an available collision warning system without the automated brake feature that would prevent or reduce the collision if the driver fails to react.
The Terrain’s standard 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. A lane departure warning system costs extra on the Encore.
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 Encore only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.
Both the Terrain and the Encore 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 Encore.
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 Encore was last qualified as a “Top Safety Pick” in 2016.
