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 Niro are reminded to check the back seat if they opened the rear door before starting out. The Ioniq Hybrid doesn’t offer a back seat reminder.
Over 200 people are killed each year when backed over by motor vehicles. The Niro EX/SX/Touring has standard Parking Collision-Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Ioniq Hybrid doesn’t offer backup collision prevention brakes.
To help make backing out of a parking space safer, the Niro 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. Only the Ioniq Hybrid SEL/Limited has a rear cross-path warning system.
Both the Niro and the Ioniq Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, 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 front and rear parking sensors.
