For enhanced safety, the front and second-row seat shoulder belts of the Hyundai Santa Fe have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Mazda CX-50 doesn’t offer pretensioners for its rear seat belts.
Both the Santa Fe and CX-50 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 CX-50’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.
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 Santa Fe are reminded to check the back seat. The CX-50 doesn’t offer a back seat reminder.
With its standard Forward Collision Avoidance Assist, the Hyundai Santa Fe is better at preventing collisions with pedestrians than the Mazda CX-50, according to the Insurance Institute for Highway Safety:

When descending a steep, off-road slope, the Santa Fe’s standard Downhill Brake Control allow you to creep down safely. The CX-50 doesn’t offer Downhill Brake Control.
To help make backing out of a parking space safer, the Santa Fe has standard Rear Cross-Traffic Collision Warning with Rear Cross-Traffic Collision-Avoidance Assist, systems which detect vehicles approaching from the sides and can automatically apply the brakes to prevent a collision. Only the CX-50 Turbo Premium Plus offers Rear Cross Traffic Braking.
Both the Santa Fe and the CX-50 have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.
The Hyundai Santa Fe weighs 430 to 780 pounds more than the Mazda CX-50. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
