Hi everyone, I really like my EV6, but it’s been such a hassle to find it dead in the morning… again. Here’s what’s happened:
KIA GT Line RWD from July 2023, 65,000 km.
At 30,000 km: The car wouldn’t open, nothing turned on. I called KIA, they took the car, updated the software, and gave it back. It seemed fine.
At 46,000 km: A battery warning came up on the screen. I was told to stop the car. KIA picked it up and replaced the ICCU. This took 7 days, and I didn’t get a replacement car until I complained.
Now at 65,000 km: A few days ago, the car was plugged into my home charger overnight. The next morning, it had no power at all. I really needed the car that day since I had to go to the hospital for surgery. I’m out of the hospital now, but I still have this mess to deal with: a dead EV6.
It’s happened three times now, and I’m losing trust in the car. I came from a Mazda that was rock-solid for years. Has anyone else faced this problem after an ICCU replacement? Any advice would be great.
I’m going down the lemon law route after replacing almost every major electrical part except the motor and still having problems. My car limits charging speed and overheats on level 2. Here’s what happened:
At 3,000 miles: Charging kept getting interrupted due to the port overheating. They applied a fix, but it reduced the charging speed.
At 8,000 miles: Critical battery failure. They replaced part of the high-voltage pack and the wiring harness.
At 12,000 miles: The charging port was replaced because it kept overheating and causing failed charges.
At 18,000 miles: The ICCU failed completely.
It’s been in the shop for nearly 50 days total in 2 years (18k miles).

What kind of speed do you get when charging at home?
I’ve got a 48a hardwired charger, which seems to be part of the problem. When it does charge, it starts at 11 kW but drops to around 7–8 kW after 15 minutes. It’s not what I was sold, but it works. When the car was new, it held 11 kW for most of the charge and only slowed down near the end, which was fine.

I wish I could go the lemon law route, but I’ve had mine too long. It overheats on level 2 charging a lot, especially in the summer. KIA hasn’t been able to fix it.
It might be worth looking into consumer protection laws where you live. If it’s been in for the same issue three times, you might be eligible for a replacement or buyback.

Thanks, but I’m in France, and we don’t have a ‘lemon law’ here.
Not ideal, but when I got my 23 GT, I swapped the original battery with an Ohmmu lithium-ion one. It’s Bluetooth-enabled, so I can check its status and even stop it from discharging if needed (though I haven’t had to do that). The app is super helpful.
I’m at 15,100 miles so far, and it’s been working great.
