I am submitting a safety complaint regarding a serious incident involving my 2025 Kia EV9. The vehicle was serviced on March 1 at World Kia in Joliet, Illinois. On April 4, only four days after that service, the vehicle experienced a sudden and unexpected ICCU failure while I was driving. During my normal travel, in active traffic and at speed, the vehicle abruptly entered limp mode and displayed multiple system warnings. This caused an immediate and significant reduction in power, creating a hazardous situation for myself and surrounding drivers. I was forced to maneuver the vehicle out of t…
Mar 18, 2026Seats
Seats allow drivers to save seating positions for different drivers. Seats automatically return to the last used saved position when the vehicle is turned on. This seat movement cannot be stopped or overridden without finding and activating the seat position controls on the left side of the seat base. If the driver does not find these controls in time, they can become crushed against the steering wheel or other surfaces. Seats do not respond to resistance and motors continue increasing torque until the controls are activated or the final saved position is reached. Problem is easily reproduced…
Mar 17, 2026Tires
These Hankook iON Evo tires started vibrating wildly at the first service that I took the car to for a rotation. We took it back to the dealership (Ourisman Kia in Fairfax VA) three times where they kept the car for several days to diagnose. After opening the tires up, they state that the inner sound insulating foam on all four tires has separated. The tires were at 7/32 and now 5/32 and the car only has 18,200 miles on it. The tires have a 50k treadwear warranty, but this isn't covered as part of the warranty. The inner foam separation on a Kia EV9 is a known issue and widely discussed on…
Feb 25, 2026Visibility/wiper
This car is unusual because the wipers are located in a crevice far below the top of the hood where it meets the windshield. The first time we had an issue, it had snowed and snow collected in the crevice area. The wipers were turned on, but the drivers side one didn't move in sync with the passenger side one. They eventually "tangled" and we stopped them. The car was taken for service and supposedly repaired by replacing one of the wiper arms that had bent. It has snowed again. Before the snow fell, the crevice was mostly covered with a shield to keep snow from falling into it. The wipe…
