I bought an EV6 in 2022, and today while driving, I got a message saying ‘Check electric vehicle system.’ I kept driving for a bit, but then another message popped up with beeping: ‘Stop vehicle and check power supply.’ I managed to pull into a parking lot, but when I turned off the car, it wouldn’t start again. I was stranded with my 4-month-old baby. Roadside assistance from the Kia app helped me, and the car was towed to the nearest dealership, but they can’t even diagnose it for another week.
Has anyone else experienced this? Is it going to be a costly repair or lead to more long-term issues? I’ve loved this car for the past two years, but this whole experience has left me so frustrated and angry. There were no warnings, nothing from the app or even after my last service a couple of months ago. The car just completely shut down right after that first message. My previous car, a 2008 Toyota Yaris, never left me stranded. I feel like I overpaid for this EV6, and now, two years later, I’m dealing with this.
Any insight would be really appreciated, especially if you’ve had something similar happen. Thanks in advance.
Sounds like the ICCU failure. There was a big recall for it that was supposed to fix this issue. It only takes an hour for the update at the dealership. I’m also a 2022 owner, and after the recall last year, no issues so far. It’s pretty common though.

Thanks for the info! I checked, and I don’t have any open recalls on my car, so I’m not sure what’s going on, but I guess I’ll just have to wait.

You can still take it to the dealership to make sure the fix was applied. If you’ve been the only owner, they should be able to just do the update for you. Definitely worth checking.
Same thing happened to me last November, right before Thanksgiving. It was the ICCU issue, along with a blown fuse. Dealership replaced everything under warranty, but it took over three weeks because of the holiday and waiting for Kia engineers. Kia reimbursed me for a rental car over Thanksgiving and provided another after I returned the first one.
I still love the car, but that experience was disappointing. Feels like we’re beta testers for this first-gen vehicle. Hopefully, the software recalls prevent any future ICCU failures.
This happened to me a month ago. My 2-year-old EV6 completely died. The dealership took 12 days just to look at it (also an ICCU issue) and another 14 days to actually fix it. They even damaged my car’s interior while replacing the ICCU, so now I need to go back for them to replace a panel.
They said they don’t have enough EV techs for non-appointment cars, so mine kept getting pushed back. The whole experience was a nightmare, and the dealership was awful at communicating. I’m seriously considering getting rid of the car. I love the EV6, but it’s not worth this stress.
It’s most likely an ICCU failure. Once it’s fixed, you shouldn’t have any more issues. It usually takes 7-10 days to repair. Did the dealership offer you a loaner car?

I have a 2022 EV6 First Edition, and I’ve had nothing but issues since buying it used earlier this year. I’ve been in and out of two dealerships for problems related to the 12v battery drain. Even after the ICCU replacement and software update, it’s still draining.
Right now, it’s at the dealership, and it’s been over three weeks. They couldn’t find anything wrong at first, but when I went to pick it up, the 12v battery was dead again. It’s been such a frustrating process, and I’ve had no real answers from Kia or the dealership. It feels like I’m getting the runaround.
I’m starting to look at other options like the Volvo C40 Recharge, Volkswagen ID.4, or even the Mustang Mach-E because I’m losing hope.
@kwame
It sounds like your issue isn’t with the ICCU but with a parasitic drain. You don’t need an EV specialist to diagnose that; any mechanic should be able to troubleshoot it.
Once the 12v drains too many times, the car’s system will stop recharging it automatically. It could be something like the VESS speaker or head unit causing the drain. Your dealership should be able to track this down easily.
