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.
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.
The Hyundai Ioniq 9 comes with a standard Surround View Monitor, while the Chrysler Pacifica doesn’t offer a camera washer, requiring manual cleaning.
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.
