2023 Kia EV6 Complaints

The ICCU fuse blew. As I was driving, the car began to lose power. Fortunately I was able to pull into a parking lot before I lost all power. It's the same issue as the recall SC327Y1 from NHTSA, which occurred although the software update had already been performed previously. The dealer is replacing the ICCU and ICCU fuse under SC327Y1 after inspecting it. I did receive a warning as I was driving that the car was low on power.

ICCU failure and IVCU fuse failure

The ICCU failed. The vehicle suddenly stopped on the road, would not go into any gear and could not be moved whatsoever, was stuck on the side of the road in a dangerous position. Called roadside assistance, after a few hours the vehicle was towed to the nearest dealership. After a week the vehicle had the ICCU replaced under warranty.

The component that is seeming to fail in most KIA EV6's is the ICCU assembly. This is the component that failed in my KIA EV6 GT.

I was able to make it to an exit driving at approximately 20-30 mph, and was able to drive it back to my house where it was then towed to a dealership. The problem has been confirmed by the dealer. I have the invoice to prove the repair of the ICCU. Yes there were warning messages on the screen when the ICCU failed. First, there was an audible "POP" which was the fuse blowing first. Once the fuse blows, it slowly kills the 12v battery and the car then looses power and you're no longer able to drive the vehicle. At that point, the ICCU is blown. The...

On April 24, 2025, I plugged my Kia EV6 into my 48-amp hardwired ChargePoint HomeFlex at 7:26 PM. Around 10:30 PM I heard a noise outside but did not investigate. At 12:25 AM I noticed I had not received a “charging complete” notification. The Kia Connect app showed the vehicle at 74% and no longer charging. The ChargePoint app was unresponsive.\n\nThe next morning I found the charger’s 60-amp breaker had tripped. After resetting the breaker and rebooting the charger, the EV6 would not start charging and displayed no “Charging started” or “Charging unsuccessful” message.\n\nI then attempted to charge using a portable Tesla Level 1 charger on a 120V GFCI outlet. The EV6 briefly announced “Charging started,” but the dash showed no charging data. The outlet’s GFCI breaker tripped. After resetting, the breaker immediately tripped again when reconnecting the vehicle.\n\nI attempted to drive to a nearby DC fast charger. Upon shifting into drive, the vehicle displayed “Check electric vehicle...
