Both the Ioniq 9 and Pilot have child safety locks to prevent children from opening the rear doors. The Ioniq 9 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 Pilot’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.
The Ioniq 9 has a standard front seat center airbag, which deploys between the driver and front passenger, protecting them from injuries caused by striking each other in serious side impacts. The Pilot doesn’t offer front seat center airbags.
Both the Ioniq 9 and Pilot have rear cross-traffic warning, but the Ioniq 9 has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The Pilot’s Cross Traffic Monitor doesn’t automatically brake.
Both the Ioniq 9 and the Pilot have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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 and available around view monitors.
The Hyundai Ioniq 9 weighs 822 to 1702 pounds more than the Honda Pilot. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
