2023 Kia EV6

On April 6, 2025, while charging my car my Juicebox tripped a breaker. When I reset it the Juicebox was showing errors and was inoperable. I tried to use my backup charger (Blink) but it tripped a breaker and became inoperable too. I took the car a commercial charger (ChargePoint) and it would not charge the car. Kept getting a “charge interrupted” message. The first Kia dealer I went to did not have a Level 2 charger and could find nothing wrong and refused to help repair the car. The second Kia dealer had a Level 2 and confirmed it would not charge, but Kia would not authorize a warranty fix. That dealer suggested leaving the car for a few days and hope the car generates a fault that Kia will accept to authorize a fix. •What component or system failed or malfunctioned, and is it available for inspection upon request? The Level 2 AC charging no longer works. •How was your safety or the safety of others put at risk? The car tripping 240-volt breakers and making two 240-volt chargers inoperable is concerning. •Has the problem been reproduced or confirmed by a dealer or independent service center? One dealer has confirmed the Level 2 charging no longer works. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by a Kia service shop •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None

I want to disclose this is the 2nd time this has happened. I was on the highway when the system failed. Immediately and drastically forced my car down to 25mph on [XXX] going to Philadelphia in the far left lane with no warning. I had to make it across 3 rows of traffic and ride on the shoulder of the highway until I could find a safe place. One ruining the sport tires on the car and probably messing up suspension since these cars are very sensitive and the highway does have those perforated shoulders. While cars zip past me I am having to figure out how to pull over with no force. None of the functions were working. It was traumatizing. Especially to do it again after 6 months ago the same thing happened. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On January 27th I was driving home on I-495 in the far left lane going about 70MPH when the electrical warning light came on. Telling me to stop the car and take to the dealership. While I was trying to get over into my far right lane, the car went from 70mph to 25 mph in about 40 seconds! Cars were flying all around me! It was terrifying and incredibly dangerous! The dealership discovered my ICCU had failed. This vehicle has a fatal flaw that is going to get someone killed.

Integrated Charge Control Unit (ICCU) failed. Charging error appeared on 30 March 2025. Next attempted to drive vehicle on 2 April 2025. Accessory battery suddenly dropped from 12V to 8V. Vehicle displayed "Stop Vehicle and Check Power Supply." Was able to crawl home in "Turtle mode" before tow to dealer. P1A90(96) [0x1A9096] among the Diagnostic Trouble Codes stored. Dealer confirmed ICCU failure and estimates at least one month to repair. SC302 was applied on 13 May 2024 at 5,732 miles. SC327 was applied on 2 Jan 2025 at 10,506 miles. 12V accessory battery is original (sealed lead acid).

ICCU failure. Car was dropped off with Kia and the (second) recall they claimed to have performed did not fix the 12-v battery charging system error. They ordered in a new part, which was on national backorder and they provided no ETA. I had to purchase a replacement vehicle after 30 days of them having the vehicle without making the repair, providing an update, or having given me a loaner. Received message it was fixed after 37 days, but no information whether it is with a new part. Subreddit for the EV6 shows this is a widespread issue that has not been permanently resolved. When the ICCU fails, you are limited to 25mph "limp mode" and will lose ability to move car if 12V battery dies.

I have received at least two recalls on the ICCU component on my Kia EV6, which were taken to the dealership for repair per the recall. On April 4, 2025, my vehicle displayed the "Check Electric Vehicle Systems" and "Stop vehicle and check power supply" alerts. It had to be towed to the dealership, as it cannot be driven. They called and stated it was related and the part is on back order for the unforeseen future.

While driving my car a warning flashed stating "check electrical vehicle system." Pulled over, contacted Kia of Abilene and asked if we could drive the car to the dealership. While on the phone another warning flashed ""Stop vehicle and check power supply." Attempted to drive car, "Limp mode or turtle mode" occurred and the max speed for the car was 25mph, sudden loss of acceleration. Made it home, which was approximately 2 miles away, and it seems like the 12V battery was draining quickly. Eventually the vehicle stalled at home and became unresponsive, no power. Contacted roadside assistance and the vehicle was towed to Kia of Abilene. All of this occurred March 29th at approximately noon. The dealership finally contacted us today, April 2nd, and notified us it was an ICCU failure and the part wasn't available with no foreseeable time-frame for repair. The car is absolutely inoperable!

driving at around 35mph I heard a pop and a warning showed up on the dash stating "stop vehicle and check power supply". This warning put the car into limp mode as I was about to turn on to a busier road to get to my place of employment. The car was then towed, at the request of Kia, to the nearest dealership. It was diagnosed a few days later as having a faulty ICCU, or integrated charging control unit. There were no indications of the problem before the loud pop which I am assuming was a fuse blowing, and the car entering limp mode and showing warnings on the dash. This is a known issue by Kia as I have had my car in for multiple recalls regarding the ICCU.
