2024 KIA EV6 Fuelpropulsion System Problems

Vehicle Information: 2024 Kia EV6 (VIN: [XXX] ) Mileage at time of failure: 14,005 Complaint Description: My 2024 Kia EV6 experienced a complete failure of the 12-volt battery system despite the high-voltage traction battery showing approximately 80% state of charge. The vehicle became completely inoperable without warning. The 12-volt battery was fully discharged and the vehicle would not enter READY mode. The vehicle required a jump start to become operational. After being jump started, the 12-volt system did not appear to charge properly, suggesting a failure of the Integrated Charging Control Unit (ICCU), which is responsible for converting high-voltage battery power to maintain the 12-volt battery. This failure created a significant safety concern because: The vehicle became completely disabled without warning. This failure occurred while driving in heavy traffic, it created a hazardous situation. The vehicle’s electrical systems, including safety systems, depend on the 12-volt battery. There are known reports...

ICCU failure

ICCU failure while driving. Vehicle defaulted into limp-home mode and required towing to a dealership once it fully died. The issue was confirmed to be the ICCU and the part was replaced.

Car suddenly slowed from 55 mph to 25 mph because of issues with the 12v battery and the ICCU system. The car is only 1 year old. From looking online, this seems to be a fairly common issue/problem. The dealer is working on it now, but it seems likely that this issue will happen again. If it happens on a freeway, certainly a safety concern.

Heard a pop, followed by power failure and warning lights to stop operating the vehicle. The ICCU unit had blown.

ICCU failed. Heard a popping sound from rear of passenger compartment, dash errors lit up, car went to limp mode

I was driving on the freeway steady at 72mph and the car suddenly accelerated on its own. It hit 90 within seconds and I had to step on the break for the car to slow down.

Description of Incident: 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The high-voltage battery system and charging system in my 2024 Kia EV6 malfunctioned. Despite showing 40 miles of range remaining, the battery suddenly dropped to 5 miles before the car became completely unresponsive and failed to charge. Additionally, the vehicle could not be shifted into neutral or powered on. The vehicle is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The sudden loss of battery range left me stranded at a Shell Recharge station in Elkridge, MD, at [XXX] on[XXX]. Being stranded at this hour posed a personal safety risk, especially in an unfamiliar area, as I was unable to move the vehicle. Moreover, the malfunction could endanger drivers if such a failure occurred while driving. 3. Has the problem been...
