2024 Kia EV6

After starting the car, a message displayed on dashboard "Check Electrical System." I tried driving the car out of the garage and then a message displayed to the effect of "Stop the car and check battery." I called the dealer and they said to have the car towed to them. After having the car towed to the dealer, they ended up replacing the Integrated Charging Control System (ICCU) and fuse. The danger is that the failure of this ICCU part could cause immediate loss of power when driving. Luckily, that didn't happen to me since I was only creeping slowly out of my garage.

* Per paperwork from the car dealer, the ICCU failed along with a 3way valve assembly and a fuse blew. * While driving, the car went into a limp mode greatly limiting its maximum speed. * I was afraid to continue driving it and had the car towed to the KIA dealership. * It took exactly a month for it to be repaired. * The dealership kept the failed parts. * No warning lamps until the failure occurred. * When the failure happened a warning message stated "Check electric vehicle system!" and a battery symbol turned red. *Since it was taking what seemed like a long time for repair, I contacted Kia-Customer-Care and they assigned case number 25902713.

I had just left my house and pulled onto a 5 lane road when the ICCU died. The car lost power while underway. This posed great danger as the vehicle became unable to safely navigate traffic and pull off to safety. Kia is well aware of this hardware problem, tried to fix it with software updates, and deflates the affected number of vehicles. To make matters worse, they tried to deny this was a recall because they claimed the recall was fixed via the software update. This affects every single Kia Hyundai and Genesis EV.

The car on 3/5 blanked out on all screens. shut car off and then came back on, no warnings came up. The car on 3/7 came up with “Check Electric Vehicle System” reverted to page 1-46 of Manual and advised do not drive, tow to nearest dealership. We drove car 4 miles home and the car had next to no acceleration, extremely dangerous and people nearing to back end us. To try and charge vehicle response is "unsuccessful"

I purchased this vehicle just over a year ago as a CPO model with only 8,000 miles on it. It now has just over 23,000 miles. In this short time of ownership, it has been back to the dealership 3 separate times for serious EV system issues. The first visit involved a software update intended to correct a 12-volt charging issue that could prevent the vehicle from charging and potentially cause ICCU failure. Shortly after that update, the 12-volt battery failed, despite being <18 months into service, completely bricking the vehicle and leaving me stranded waiting for a tow. The battery was replaced under warranty. Less than 2 months later, while >30 miles from home, the vehicle displayed a “Check Electrical System Failure” warning. I was able to limp-mode the car back to the dealership. I am now being told that the main EV battery has failed and must be replaced, possibly also the ICCU. The dealership cannot provide a firm timeline for repairs; parts availability could mean anywhere from 2 weeks to 4 months without the vehicle. This pattern of failures raises serious concerns about the reliability and safety of the EV6. Repeated electrical system issues create a very real risk of being stranded unexpectedly, potentially in unsafe situations such as on the side of a highway. To date, I have already lost four days of use due to service repairs, and I now face being without the vehicle for an extended and uncertain period. While a loaner vehicle is being provided, I will incur fuel expenses at a time of rising gas prices, undermining the financial rationale for purchasing an EV. Meanwhile, I continue making payments on a vehicle I cannot use, which is depreciating in value. I understand that new technology carries some risk. However, despite prior updates and even a model refresh, the ICCU issue appears unresolved, and Kia does not seem to have a clear root cause identified. For a vehicle marketed on innovation and dependability, this experience has indicated otherwise.

The Integrated Charging Control Unit (ICCU) of my KIA EV6 failed. When putting the car into reverse to leave my workplace, I heard a fuse pop and a notification appeared on dashboard screen saying "Check electric vehicle system". This is a known recall issue that I was aware could happen, and in which case the car will soon become completely inoperable, so I didn't risking driving further. I had it towed to the nearest KIA dealership, where they confirmed the ICCU had failed and replaced it at no charge under the warranty coverage. There were no warnings or symptoms prior to the failure. I was fortunate that it did not fail while I was driving.

The driver (my wife) was operating the Kia EV6 (with approximately 10,000 miles) when the vehicle suddenly experienced a severe loss of motive power. While driving, a warning message appeared on the dashboard indicating an issue with the power supply. Immediately after, the vehicle forced itself into "turtle mode," severely restricting the maximum speed to 20 mph and refusing to accelerate further. This sudden, unexpected deceleration on an active roadway put the driver at a significant risk of a rear-end collision. The driver managed to slowly navigate the vehicle back to our residence at a maximum speed of 20 mph, which was extremely hazardous. Shortly after safely parking at the residence, the vehicle experienced a complete electrical failure. It would no longer start, could not be shifted into neutral, and ultimately had to be dragged onto a flatbed tow truck by roadside assistance because the wheels were locked. The vehicle was towed to an authorized Kia dealership, where it is currently undergoing diagnosis and inspection for what is heavily suspected to be a total failure of the Integrated Charging Control Unit (ICCU) and 12-volt battery system. The vehicle and the failed components are currently at the dealership and are available for inspection upon request. Note: This catastrophic power loss occurred just weeks after the vehicle was in the shop for nearly a month to have its entire high-voltage battery pack replaced due to severe range degradation, marking the second major electrical system failure on this vehicle.
