Both the Santa Fe and Niro have child safety locks to prevent children from opening the rear doors. The Santa Fe has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Niro’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.
Over 200 people are killed each year when backed over by motor vehicles. The Santa Fe Limited/Calligraphy has standard Parking Collision Avoidance Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Niro doesn’t offer backup collision prevention brakes.
The Santa Fe offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Niro doesn’t offer all-wheel drive.
The Santa Fe Limited/Calligraphy has a standard Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Niro 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.
The Santa Fe has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. Only the Niro LXS/Touring/Touring Special Edition/EX Premium offers a blind spot warning system.
To help make backing out of a parking space safer, the Santa Fe has a standard 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 Niro LXS/Touring/Touring Special Edition/EX Premium has a cross-path warning system.
The Santa Fe SEL/Limited/Calligraphy has a standard Blue Link, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Niro doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Santa Fe and the Niro have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
The Hyundai Santa Fe weighs 422 to 976 pounds more than the Kia Niro. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
