ELECTRICAL SYSTEM
As I was driving, there was a loud pop that came from the rear of the car. The vehicle immediately flashed a warning to “check electrical systems”. I pulled over as quickly as possible but was faced with reduced acceleration. I ended up stuck in a parking lot awaiting a tow truck for over an hour with my dog and my wife in the car headed to a surgery appointment. The dealership has not confirmed anything but from research it seems to be a known issue that Kia has not addressed.

ELECTRICAL SYSTEM, POWER TRAIN, FUEL/PROPULSION SYSTEM
2024 Kia EV6 leased January 2025. Vehicle is subject to NHTSA Recall 24V-867 / Kia campaign SC327 for the Integrated Charging Control Unit (ICCU). The recall remedy was performed at an authorized Kia dealer in July 2025 (software / operational logic update). The defect was not cured. Three months after the recall remedy was performed, the vehicle suffered complete loss of electrical power and would not move. It was towed to the Kia dealer. The dealer's own diagnostic recorded code P1A9096 — the exact diagnostic code Kia's recall instructs technicians to check for — and replaced the ICCU and high-voltage fuse. This is the recall-defined failure occurring AFTER the recall remedy was applied. Approximately three months later, the vehicle again suffered total loss of power and would not start in cold weather. It was towed in. The dealer replaced only the 12-volt battery and did not address the ICCU, despite the documented prior ICCU failure on this VIN. The 12V battery failure is a known downstream symptom of ICCU failure on this platform. Approximately one month after that, the vehicle returned for charging system failure ("vehicle charges briefly then stops") and a "check electrical/hybrid system" warning that appeared while driving. Diagnosed as charging port failure. Vehicle was out of service approximately 27 consecutive days. Total cumulative days out of service across four visits: approximately 35-40. Two safety-related stranding incidents resulted from these failures. Both occurred in winter conditions in Pennsylvania. In the first, the driver was stranded in a parking lot at night during a snowstorm in sub-zero conditions; three tow trucks were dispatched before a flatbed could recover the vehicle because the EV could not be towed conventionally with no power. In the second, the vehicle died in a school parking lot during a snowstorm; the first dispatched tow truck could not recover an EV with no power, and the driver had to walk multiple miles home in freezing

ELECTRICAL SYSTEM, POWER TRAIN
ICCU failed despite all prior recall updates being performed. Incident began when home circuit breaker tripped; vehicle subsequently refused Level 1 charging with "Check Electrical System" warning. Per dealer suggestion, tested public chargers. Level 3 (DC) worked, but upon connecting to Level 2 (AC/J1772), a loud "pop" occurred, and the public charging station immediately suffered a mechanical failure/shutdown. Vehicle then displayed "Stop vehicle and check power supply," and was unable to drive above 40mph (with a turtle icon visible on the dash) once I pulled away from the charging station. This created a significant safety hazard while navigating traffic. Within two hours, the 12V battery was completely depleted; vehicle was unresponsive and required a jump-start for towing. Dealer confirmed ICCU failure requiring replacement. The fact that the vehicle's internal failure caused the immediate malfunction of public infrastructure is deeply concerning, as was the loss of motive power on the road.

POWER TRAIN
Vehicle display showed a message stating 12 volt battery was low and to pull over immediately, the car the died in a parking lot. I called KIA roadside service and they connected a battery pack to the 12 volt battery and got the car started. This could have been a serious problem if I was on travelling on a public street or highway and suddenly lost power.

ELECTRICAL SYSTEM
The Integrated Charging Control Unit (ICCU) failed twice within four weeks. The first failure occurred in March 2026 and was repaired under recall SC327 with a replacement ICCU and fuse. The second failure occurred April 7, 2026, approximately 12 days after pickup. Symptoms: Vehicle failed to charge overnight on Level 1 and Level 2 circuits despite being plugged in. Later that day, while driving, a “Check Electrical System” warning appeared on the dashboard followed by sudden loss of power and acceleration. Vehicle fluctuated between 25-45 mph and could not maintain speed. Vehicle was driven approximately 2.2 miles to the dealership under its own power after warning onset. Safety risk: Sudden loss of power and acceleration while driving created a hazardous condition for myself. Dealer confirmation: The authorized Kia dealer confirmed a DTC for battery overheating and acknowledged the ICCU coolant was not fully topped off after the first replacement, suggesting the recall remedy was incompletely performed. The vehicle has remained at the dealer unrepaired since April 10, 2026. Component available for inspection: Yes, vehicle is currently at the dealership. Recall remedy concern: The SC327 recall remedy did not resolve the ICCU failure. A second failure occurred within two weeks of the repair. The dealer’s subsequent diagnosis of owner-caused undercarriage battery damage is contradicted by their own signed inspection report documenting all undercarriage items as passed with no damage noted

Listing as all 3. ICCU/fuse went out, car decelerated to 45 MPH max and flashed a warning to pull over. The bottom left battery indicator for the 12v battery also changed to red, indicating it was not regaining power from the main EV battery. Currently in shop hoping to get part in soon

ELECTRICAL SYSTEM
My vehicle has been in the possession of Koons Kia of Owings Mills since March 15, 2026, for diagnosis and repair of this issue, with service beginning March 16, 2026. During this time, the dealership has replaced the 12-volt battery and performed a software update; however, the defect has not been corrected. On April 10, 2026, I was notified that the vehicle was ready for pickup. When I arrived on April 11, I found that the battery was completely discharged and the issue had not been resolved. Because the vehicle was not operational at the time of attempted pickup, it was not returned to me and remained in the dealership’s possession. I was contacted again on April 13, 2026, and informed that the vehicle had been repaired. When I returned to the dealership on April 14 to retrieve the vehicle, I again found that the battery was discharged and the defect persisted. As a result, the vehicle was not returned to me and has remained continuously in the dealership’s possession since March 15, 2026. As of today, the vehicle has been out of service for more than 30 consecutive days due to this defect, and multiple repair efforts have failed to resolve the issue. This ongoing condition substantially impairs the use, value, and reliability of the vehicle.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was backing out of my driveway and backed into a vehicle parked directly behind me. The collision avoidance and emergency braking system should have stopped my car before impact but it did not. No sounds other than the normal backing up beeping. Proximity alert did not ping. The vehicle is available for inspection upon request. The safety feature of collision avoidance and emergency breaking did not work. No, the problem has not been reproduced or confirmed by a dealer or independent service center. No, the vehicle component has not been inspected by the manufacturer, police, insurance representative or other. The police were called to the scene, they just looked at the damage on both vehicles. No warning lamps, messages or other symptoms of the problem prior to the failure. They only appeared once on the day of the accident. I can confirm the backup collision avoidance worked after the incident since the emergency breaking stopped my car in a parking lot after the incident of the failure.

The vehicle’s ICCU unit stopped working out of the blue. This happened on a busy intersection and the car came to a sudden and violent halt. Luckily we were not involved in an accident. It’s a very well known issue with these vehicles and it’s really criminal that Kia has done nothing to fix it. They just change the ICCU unit and then it happens again.

ELECTRICAL SYSTEM
While driving Friday 4/17/26, I heard a pop and the car displayed a message to "Check electric vehicle system." The car seemed to still drive so I drive it home. That evening the car would not charge. I called Jim Shorkey Kia on 4/18/26, where I bought the car, to schedule the car to be looked at. They told me to bring it in on Monday and they will try to squeeze me in so they can diagnose the issue. Later that morning, I took that car out and made it about a block away before the car displayed a new message to "Stop vehicle and check power supply." At this point, the car went into a limp mode, barely moving. I was able to turn around and drive it home. Had I been on the highway, I might have been put in a dangerous situation. Now that the car has been diagnosed, the service department called and told me that the failed component was the ICCU. From what I've read, Kia claims that 1% of cars suffer from this issue. However, this percentage seems unlikely due to the number of online complaints. I wanted my experience to be an official documented case of this since I've heard that Kia has issued limited recalls in other countries and on older model Kia EV6's in the US.

UNKNOWN OR OTHER
KIA has created a safety hazard by removing the ability for the driver to select LIGHT or DARK mode for the two 7" data and infotainment screens in their 2025 and forward EV6 electric cars. Like many, I have to drive in very fast busy commuter traffic on highway I-66. (exaserbated by driving into the sun in the AM) The DARK mode screens have insufficient contrast even with the screen lighting turned all the way up. It takes the drivers eyes away from the road longer than is safe, particularly in high speed freeway commuter traffic. This is seriously exacerbated if the driver uses sunglasses because of the sun. This is obviously not an issue confined to highway I-66, or me.

ELECTRICAL SYSTEM:PROPULSION SYSTEM:CHARGING:MODULE:ACCESSORY
Went to charge my vehicle in my garage on 4/15/26. When it was fully charged, I reached to disconnect the charger from the vehicle and the connector was hot to the touch; the charging hub on the vehicle was also hot, the charger had a slight plastic burning smell. I immediately tried to contact the company and learned that they had unbeknownst to me, ceased conducting operations in the US. So I ordered a new charger. I also tried it again on 4/17/26; and the heat was higher faster than it was on 4/15/26; so I hav disconnected the device and installed a new one. The electrician noted that the breaker was damaged and had to be replaced. I also recall, that a few months after the initial install of the charger, there was an incident where my wife saw sparks in the garage from the breaker and we heard a large pop; and then the charger went out. The company sent us a new one then that worked fine for a few years.

Got in my car to leave a store and heard a loud pop and noticed a smell like an electric motor burning. Backed out of my space to drive home and the car displayed several error messages- Check electric vehicle system, turtle mode, power reduced. I was stranded and had to order a tow truck to be towed to the dealer and get a ride home.
