Heard a loud pop from rear passenger side of vehicle followed by dash warning lights to check charging system, then pull vehicle over immediately. All power to the vehicle was subsequently lost immobilizing the vehicle. Dealer service department said ICCU board needs to be replaced, but is on national backorder. Car has been immobilized since.

After driving my vehicle for a few minutes on my way to work my car lost speed rapidly, going from 40 mph to 25 then seconds later to 22 mph. I tried to accelerate; the car was unresponsive and would not accelerate over 22 mph. Dropping speed rapidly and suddenly during rush hour on a secondary road with a limited shoulder was unnerving as the slow response required waiting for a gap in traffic flow to safely turn around to head home. Upon returning home a message appeared on right side of dash board in an orange circle "check vehicle system" with a small upside down triangle with letters EV also inside this circle and a "small orange battery" picture showed on the left. I called Kia Roadside Assistance and reported the above and was advised it would take about 90 minutes for a tow to dealer as I was unwilling to drive it. Once the tow truck arrived I tried to drive EV6 out of my driveway onto flatbed and it died halfway. Driver had to jump 12 volt to get car to start and maintain power to get up flatbed. He advised 12 volt had to stay connected to ensure power to deliver to dealership. After weeks of calling / emailing dealer, opening a case with Kia America and sending several unanswered tweets the dealer advised on 06/02 that tech determined the ICCU assembly and a new high voltage fuse would be required. The service manager advised this would take 7-10 business days but on 06/15 advised the parts had still not arrived and in following up with Kia America there was no available ETA on when the part would be received.

Issue has been diagnosed by Kia and our dealership as a failed Integrated Control Charging Unit (ICCU). Parts are backordered indefinitely (we were told there's 106 on order nationally). Same issue as the Hyundai Ioniq 5 (which is built on the same platform): https://news.yahoo.com/highway-safety-agency-reports-power-162735107.html Car dash showed a "Check electric vehicle system" alert, followed shortly after by "Stop vehicle and check power supply" on a short city drive home. Was close enough to make it home without the car turning off, where I confirmed the car could also no longer be charged at home using AC charging. The ICCU manages AC to DC power conversion for home charging and also keeps the 12-volt battery charged. Per Kia's recommendation, had the car towed to the nearest dealership. The worst part is just the wait time for backordered parts that Kia and Hyundai; dealership can't even give us an estimate of when to expect the parts. 107 does not seem like a difficult number of components to come up with on short notice for a carmaker that sells 2.3 million cars annually.

Vehicle suddenly showed warning for electrical failure and could not longer be driven. Towed to dealership. Main fuse was blown. After waiting a couple of weeks for that part to arrive, it was replaced, only to find out that another component had failed; the ICCU. Kia stating there is NO ETA on when this part will be available. Car had been at dealership for almost 5 weeks with their admission that no estimate exists for when the car will be repaired due to the unknown time to wait for the part.

I was traveling on a neighborhood arterial road, when I heard a load thunk that seemed to come from beneath the rear seat. Moments later, I got a "Check electric vehicle system" warning, followed by "Stop vehicle and check power supply" in the dashboard. After another moment, the power was reduced to a maximum of 25 mph. I turned on the hazard lights because I was no longer able to match the flow of traffic (45 mph). No accident occurred. I was able to limp the car home on slower side streets. At home, I eventually got a "12v battery voltage low" message and the car was unable to move. I had to have the car towed to the dealership. The dealer service folks diagnosed the problem as a failed integrated charging control unit (ICCU). This same problem has been reported by others in the Kia EV forums. Kia Consumer Affairs says 87 of those parts are on backorder in the US with no ETA from Korea. Apparently, the part needs to be manufactured; they don't have them available in a warehouse.

I was driving my less than 1 year old, only 10,000 miles Kia EV6 First Edition when I got an error message to 'Check Vehicle Electric System'. After about another 2 miles I got a warning to "Stop Vehicle and Check Power Supply." As I attempted to find a safe place to stop, my vehicle started throttling my speed down to only 20mph (I was on a 55mph road). I was able to pull off and into a parking lot, but when I turned the vehicle off, it was completely dead and would not restart. Note, the battery was charged to 83% at the time of this incident. I had the vehicle towed the Kia Service Center at the dealership where I purchased the vehicle. After 5 days, they informed me that the ICCU had failed. Per their website, the Integrated Charging Control Unit, or ICCU, is a newly developed integrated charging system by Hyundai that charges both the high-voltage and spare batteries, essential to allowing for V2L (Vehicle to Load) feature. It has now been 20 days since the incident and Kia has no idea when a replacement part will be available.

While operating and driving on a busy two lane roadway, about an hour in to a two hour trip, the vehicle displayed -??check electrical system-?? message without warning, then quickly lost power, rendering the car only able to drive at 25 mph for a brief moment, and then, just as quickly, shut down completely and did not operate. I was able to navigate the vehicle from the busy roadway to the roadside, but I barely made it. Under different conditions, such as travel on an interstate at high speeds, this would have proved very dangerous to have a car stop completely dead like this. The car was unable to be started by Emergency Roadside Assistance and had to be towed to the dealer. After a few days the dealer informed me that parts needed for repair would be approximately 7 weeks to be received from the manufacturer.

Battery on a 10 month old car totally failed. All electrical components died. Car would not start. Electronic transmission and no way to put it in neutral to push off road!

The on-board charge controller on my EV is drawing excessive current from my Level 2 EVSE portable charger. When my charger is set to 24 amps maximum the car will draw 28 to 30 amps, causing the charger to shutdown and report a short-circuit has been detected. When my charger is set to 40 amps, about an hour into charging the car will draw 46.6 amps again causing the charger to shut down and indicate a short-circuit. My understanding of the Level 2 charging standard is that the charger tells the vehicle its current setting and the vehicle is not supposed to draw more current than the charger tells it. I've done lots of reading online and this is a problem EV6 and Ioniq 5 owners are having with a variety of charger brands and some owners state that the same charger when used with other vehicles like the Mustang Mach E does NOT draw more current than the charger is set to. It seems to me like this is a HUGE safety issue, as excessive current draw is causing the charge cable to get hot and could cause a fire. Kia hasn't indicated any willingness to fix the problem and they don't seem to be treating it with the seriousness it deserves. I took my car to the dealer and they grudgingly applied the only Level 2 software update they had, but it has not made any difference in the problem. Now they say there is nothing else they can do.

The 12V Battery running out of charge or discharging causes the car to become inoperable. You are no longer able to lock doors, turn on hazard lights, headlights, air conditioning. A display appears when the 12V does not have sufficient charge but not until you try to turn the car on again. Otherwise no indication leaving one stranded in completely unsafe situations when you-??re not able to lock a door.

I live in the Northern Latitudes in Washington state, on my drive this morning with temps in the low 40's and high humidity the heating/ventilation system just stopped working. My windshield immediately fogged up completely and I had near zero visibility. I slowed down and thankfully had a cloth nearby and used that to wipe the windshield clear while looking for a place to pull over. After changing every conceivable setting to no avail I limped home with my cloth at hand. This is a serious safety problem that could easily lead to a serious accident. I've contacted the Kia dealer for assistance and they insist there are no known issues or bulletins on this problem. I checked various user forums for the vehicle and it appears others are having similar if not identical issues.
