This make/model has a known ICCU issue. Ours went out just after warranty expired and the cost is $4,000. The EU and some Asian countries have extended the warranty of this fault due to how prevalent it is.

ICCU and fuse failure when it was being moved out from the garage. Got a “Check electrical system” notification when I turned it on following a level 2 charge the night before. It was with the dealer for exactly one month before I was able to pick it back up.

ELECTRICAL SYSTEM
ICCU failure at 16k miles. The ICCU was replaced at the dealership on January, 29th of this year, so it is not available for inspection. The failure tripped a breaker at my home while it was charging possibly indicating a short circuit. The short circuit could have potentioally overheated and caught fire in my home. I took the vehicle to the dealership and they confirmed it was the ICCU and replaced it under warranty. I have a copy of the invoice received after the replacement was installed. I do not know what they did with the old ICCU after it was placed. There was no indication of pending failure that I noticed prior to this incident occuring.

ELECTRICAL SYSTEM
While driving on a sunny day on a 35mph road, my dashboard reported “Check Electrical Vehicle System”. A red battery symbol appeared and my cruise control disengaged with a message “requirements not met”. When I got home I read my 12 volt battery monitor that reported the battery was 11.99v and only had a 60% state of charge. Just prior to this short drive from home, my battery was 12.77v and had a 100% state of charge. I put in my ODB reader and it provided two error codes: P1A9096 and P1A961C. The first error code is the result of an ICCU failure in its DC to DC circuit (the one that charges the 12V battery from traction battery). Using a battery charger, I was able to fully recharge the 12volt battery. My monitor says that it’s healthy with 100% state of charge. Turning the car back on resulted in a rapid drain of the battery from 100% to 93% in just five minutes while parked. The electrical system failure warning lights are still lit. I’m having my car towed for repair. If this failure had occurred more than 10 minutes from my home, I would’ve been stranded.

UNKNOWN OR OTHER, ELECTRICAL SYSTEM
I had just finished charging the vehicle overnight on a Level 2 charger at a family members home. After leaving the driveway and driving a few hundred feet, an error message showed on the vehicle screen saying "Check Electric Vehicle" system, and then later a second message that said to stop the vehicle. I immediately turned the car around parked it in the driveway again and called roadside assistance to have it towed to the Kia service center. The Kia service center confirmed that it was an ICCU (integrated charging control unit) failure, which they replaced 4-5 days later after ordering the part. These error messages were the first and only indicator of the problem, there were no smaller issues leading up to the issue. Because the failure happened within a block of a family member's home, I was able to get to safety. But it could have been a completely different situation had the failure occurred even a few minutes later when I was on the freeway.

ELECTRICAL SYSTEM
Electrical propulsion failure resulting in 3 tow-ins. Vehicle goes into limp mode, slows to 20 mph on highway and then stops after about 2 miles. The issue appears related to the ICCU, fuse and 12V battery failures. History includes 6 attached ICCU related Repairs. #1 ICCU updated under recall SC271 at 31,678 miles. #2 Then the ICCU was replaced under recall SC302 at 45,059 miles. #3 Then the ICCU was replaced along with fuse and 12V battery after on road failure and tow in at 52,296 miles. #4 Then the ICCU was updated under recall SC327. #5 Then the ICCU, fuse and 12V battery was replaced at 69,849 miles under recall SC327 after another on road failure and tow in. #6 Then there was a ICCU overheat and charging fault related to a bad ICCU coolant reservoir cap after a charging failure and tow in at 70,957 miles.

ELECTRICAL SYSTEM
The contact owns a 2022 Kia EV6. The contact received notification of NHTSA Campaign Number: 24V867000 (Electrical System) and the vehicle was repaired at the local dealer. The contact stated that four months later while driving 75 MPH, there was a popping sound coming from the rear of the vehicle. The message to "Check Electrical System" was displayed, and the vehicle unexpectedly decelerated to approximately 45 MPH. The contact continued driving and the message to "Stop Vehicle and Check Power Supply" was displayed. The vehicle decelerated to 5 MPH and failed to accelerate as intended. The vehicle was pulled over to the side of the road and inspected. All the doors were unlocked, and the vehicle then stalled. The vehicle failed to restart. The vehicle was towed to a dealer where it was diagnosed and determined that the Integrated Charging Control Unit (ICCU) assembly and fuse needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 148,309.

ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL, FUEL/PROPULSION SYSTEM
I was driving 40mph and received a yellow error message along the lines of "electrical system issue, please check" and my speed was limited to 25mph. After trying to get the car to a safe location (as I was on a narrow two-lane road), the error changed to a blinking red error and my speed was further limited to 12mph. I was unable to get the car one mile to the dealer for service, so I stopped the car in a parking lot and had it towed to the dealer. The dealer diagnosed the problem and replaced the ICCU (2nd time on this car) and the 12 volt battery.

ELECTRICAL SYSTEM
The car has 41,000 miles and has experienced the second failure of the ICCU, so it will have a third unit in 3 years. The noteworthy issue is the risk associated with these failures. The unit failed on the freeway, and power was reduced to 20% (estimate), which put me and others in danger. This is apparently a known and significant issue with KIA. As a consumer, I am extremely concerned it will experience a 3rd failure, which could include immediate risk to self and passengers. How is this acceptable? Thanks for providing the forum to discuss.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The contact owns a 2022 Kia EV6. The contact stated that while driving approximately 64 MPH, the left side of the steering wheel seized, and the vehicle aggressively jerked to the left into oncoming traffic. The message “Smart Cruise Disabled” was displayed. The contact was able to quickly regain control of the vehicle. The dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The approximate failure mileage was 65,300.

ELECTRICAL SYSTEM
My (EV6) failed to charge on both Level 1 and Level 2 charging. A “Check Electrical Vehicle System” message appeared on my dashboard. I took my vehicle to my nearest dealership, where the technician confirmed a faulty ICCU. Fortunately, my vehicle was drivable, and this failure occurred at home rather than on the highway, which could have been a significantly more serious issue. A part has been ordered, and the vehicle has been in the shop going on two weeks.

FUEL/PROPULSION SYSTEM
Was backing out of a parking lot space when a loud popping sound was heard from the right rear portion of the car. Shortly after a check electrical system message was displayed and to pull over. Then eventually had a power limited message pop up after 12V battery charging status/condition was checked by roadside service. Would turn out to be the ICCU (Integrated Charging Control Unit) after dealership nearby (Peak Kia) was able to diagnose the problem. Unknown if the failed part is available for inspection. I wouldn't say my safety or others safety was put at immediate risk, but could have been since the car did eventually completely shut down right as I was able to get home only about 1-2 miles away. Vehicle was seen by dealership a few days later and as far as I'm aware are the only entity to do an inspection on the vehicle. No prior warning of any kind before the ICCU failed, and car had complied with all recalls that were supposed to prevent or at least reduce chances of ICCU issues.

The ICCU failed which was part of the recall. Kia is unwilling to honor repairs beyond the 100,000 mile warranty which is unacceptable because there is still no resolution and it is subject to potential future failure. I need an extended warranty.
