Both the Sorento and MDX have child safety locks to prevent children from opening the rear doors. The Sorento 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 MDX’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.
With its standard Forward Collision-Avoidance Assist, the Kia Sorento is better at preventing collisions with pedestrians than the Acura MDX, according to the Insurance Institute for Highway Safety:

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Kia Sorento achieved a “Good” rating - the highest possible - in forward collision warning and automatic braking systems, outperforming the Acura MDX which scored only an “Acceptable” in these critical safety features.
When descending a steep, off-road slope, the Sorento’s standard Downhill Brake Control allows you to creep down safely. The MDX doesn’t offer Downhill Brake Control.
Both the Sorento and MDX have rear cross-traffic warning, but the Sorento has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The MDX’s Rear Cross Traffic Monitor doesn’t automatically brake.
Both the Sorento and the MDX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear 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, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Kia Sorento is safer than the Acura MDX:

The Kia Sorento has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2025 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The MDX is only a standard “Top Safety Pick” for 2025.
