FUEL/PROPULSION SYSTEM, ELECTRICAL SYSTEM
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.

POWER TRAIN, ELECTRICAL SYSTEM
ICCU failure. Car lost power while driving. I heard a "pop" sound and then the car displayed a warning light moments before losing power. Car was towed to the dealership where they diagnosed and replaced the ICCU and a fuse. This is a known problem since the 2022 model year and seems to be a very common failure that the manufacturer is unable definitively repair. Thankfully I was on a local street and not on a highspeed highway when this occurred.

ELECTRICAL SYSTEM
The ICCU unit failed and the car first slowed and then stopped. I was able to pull off the road at an intersection. A tow truck had to jump charge the battery to allow the car to be shifted into neutral in order to pull it onto the tow truck.

Was trying to drive EV. As soon as I pulled out of driveway it gave me a warning sign; to check electrical system/stop vehicle and check power supply. I couldn't drive car anywhere, had to get it towed to dealership. When tow truck arrived we couldn't turn car on, it had no power. Mind you, I had full charge on EV.

My car was / is one of thousands of Kia cars based on the eGMP platform to experience an ICCU failure. This is believed to be a design issue. While the repair was covered, reports indicate that the problem is not solved and will re-occur in time.

ELECTRICAL SYSTEM
* 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.

ELECTRICAL SYSTEM, ENGINE
I am reporting a recurring safety and reliability issue with my 2022 Kia EV6 GT-Line (VIN: [XXX] ). The vehicle currently has approximately 63,100 miles. The vehicle repeatedly displays a “Check Electric Vehicle System” warning message. This problem has occurred three separate times. On at least two occasions, the vehicle became undriveable and required towing. The failure appears to affect the vehicle’s electric powertrain or control systems. The vehicle is currently being taken again to the dealership (Lou Sobh Kia in Cumming, Georgia) for diagnosis of the same issue. This will be the third service visit for this recurring failure. Because this issue can cause the vehicle to become unexpectedly inoperable, I am concerned about the safety implications and believe it may indicate a broader defect affecting Kia EV6 vehicles.

ELECTRICAL SYSTEM
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.

VISIBILITY/WIPER
Windshield cracking on new Kia EV6 with only 2700 miles. Was 53 degrees outside so no defroster excuse. Seems to be a stress crack and looking online in KIA EV6 Forums, I've noticed it is not a one-off problem as many owners have had to deal with this.

Perhaps 1 year into owning this car the apple carplay connection started going in and out-- it takes perhaps 10 to 15 seconds for it to start working again. I've tried different phones and cords. This issue is getting worse, sometimes 6 times in a 20 minute drive. Now it goes out very frequently (though it is rare in the mornings for some reason). I have brought the car into a dealership and they cannot find any issue with the car. At the recommendation of the dealership I switched the cord to an official apple cord, but when I did this the connection would be lost and I'd have to reach down, disconnect the cord, and reconnect it to get the screen to come back on-- I have since switched back to an Anker cord. There have been many drivers with the same EV6 reporting this issue in Kia FB groups. Now that the car is about 4 years old, it happens very frequently (one time 6 times in a 10 minute span). The safety issue comes in as one, some people may be reaching to disconnect and reconnect their cord while driving, which can be a distraction and may lead to increase in accidents, two, if someone is on a call they may disconnect the cord and switch to speaker, which again is a distraction, and three, I have also been using the navigation system through the carplay, and when the map goes out my turn is going up it can cause me to hesitate on whether to turn or not (and perhaps if the screen comes on at the last minute, make a quick turn, which can increase risk of collision).
