“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. …”
