For enhanced safety, the front and second-row seat shoulder belts of the Hyundai Ioniq 9 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 Chrysler Pacifica doesn’t offer pretensioners for its second-row seat belts.
Both the Ioniq 9 and Pacifica 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 Pacifica’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 Pacifica doesn’t offer front seat center airbags.
With its standard Forward Collision Avoidance Assist, the Hyundai Ioniq 9 is better at preventing collisions with pedestrians than the Chrysler Pacifica, 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 Hyundai Ioniq 9 achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Chrysler Pacifica has not been tested.
When descending a steep, off-road slope, the Ioniq 9’s standard Downhill Brake Control allows you to creep down safely. The Pacifica doesn’t offer Downhill Brake Control.
Both the Ioniq 9 and Pacifica 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 Pacifica’s Rear Cross Path Detection doesn’t automatically brake.
The Ioniq 9’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Pacifica doesn’t offer a driver alert monitor.
Both the Ioniq 9 and the Pacifica 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 and available around view monitors.
The Hyundai Ioniq 9 weighs 413 to 1487 pounds more than the Chrysler Pacifica. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Insurance Institute for Highway Safety does 40 MPH moderate front offset crash tests on new cars. In this updated test, results indicate that the Ioniq 9 is much safer than the Pacifica:

Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Hyundai Ioniq 9 is safer than the Pacifica:

The Hyundai Ioniq 9 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 Pacifica is not even a standard “Top Safety Pick” for 2025.
