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.
On January 23 2025, while driving on the highway, the car lost power an had limited control. The car was towed to a dealer and it was determined that the ICCU failed. The car was at the dealer three weeks earlier for a recall related to the ICCU (ICCU (SC273A VCU SW LOGIC UPGRADE (VSC) • SC273A and ICCU INSPECTION/REPLACEMENT…

On January 23 2025, while driving on the highway, the car lost power an had limited control. The car was towed to a dealer and it was determined that the ICCU failed. The car was at the dealer three weeks earlier for a recall related to the ICCU (ICCU (SC273A VCU SW LOGIC UPGRADE (VSC) • SC273A and ICCU INSPECTION/REPLACEMENT • SC302 ). Obviously, the recalls did not prevent the ICCU failure.
2023 Kia EV6 GT Line model. ICCU failed around 25k miles despite having the required software update as per the initial recall.

I have had 3 incidents where the ev6 went out of power. The one recent incident is when the car suddenly started giving red alert on low power and suddenly slowing down even when I try to step on the pedal to accelerate. Please see my video and photos of these incidents. And all these times my main battery of ev6 was always having charge higher than 40%. I was driving on all 3 occasions, once on highway close to the exit where I had to pull over to curbside. The ev6 has hence lost my trust since these type of sudden power failures could lead to my life straight being on risk - the 12 volt battery has died two times after I purchased the car in feb 2023! Kia themselves do not know what issues exist in the car- the recalls have happened three times, as I type this my ev6 is sitting at the west gate Kia service in wake forest, North Carolina since 17 days for a spare part called ICCU recall and replacement! I have been forced to lay an amount of $745 on this car every month and it’s draining me out financially and mentally. the worst part is since this is electric car , and you run out of battery power then it suddenly halts, if you are on high speed road on freeway no doubt you get hit by the car behind you and you die. I am not willing to put my life and my family’s life on danger when I drive this car anymore. Kia is not willing to buyback the car, I have paid a very high price for this and my car value has come down, leaving me a sum of more than around $10000 difference when I try to sell it back to Kia. This is injustice given that my life is in danger, I might face this experience again when Kia ev6 shuts on the power while I am on road, and I will get hit bythe car behind me and die. I need justice, I need Kia to buy my car back asap. I do not need to pay 745 monthly for this [XXX] car. Please help. Thanks, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was on my way to the highway when about one mile from home when without warning vehicle went into Limp Mode. Acceleration suddenly dropped to 25mph. It was very dangerous trying to drive uphill on a busy road at limited power to get back to my home. Thankfully I was not yet on the highway. Dealer said that both the ICCU and fuse that were inspected a month ago due to a recall and found to have no error codes in January now need to be replaced. Parts on back order with no ETA.
I purchased my 2023 Kia EV6 in December 28, 2024. On January 8, 2025, I took my EV6 in for the SC327 recall service. Despite completion of the recall service, my ICCU still failed and my car lost power while driving on February 6, 2025. I was driving 45 mph down a state road and was about to get into a highway onramp when my sp…

I purchased my 2023 Kia EV6 in December 28, 2024. On January 8, 2025, I took my EV6 in for the SC327 recall service. Despite completion of the recall service, my ICCU still failed and my car lost power while driving on February 6, 2025. I was driving 45 mph down a state road and was about to get into a highway onramp when my speed quickly dropped to 13 mph and my car displayed a "check electrical system" warning. The car would not go above 13 mph. I was fortunate that no one was following close behind me and that I was not on the highway. Had I been in front of a truck or other vehicle that couldn't stop quickly, the sudden deceleration could have been very dangerous. I was fortunate that I was near a parking lot that I could pull into to wait for a tow truck. By the time I got into the parking lot my car completely died and I was stuck without heat in 19 degree F weather. There were no symptoms prior to the failure, and the first warning about the electrical system ("Stop vehicle and check power supply") appeared after I lost acceleration. This warning was followed by "12 volt battery low. Stop safely." before it died completely. The vehicle is currently at the Kia Dealership pending repair.

The EV-6 GT auto experienced a loud clunking grinding noise while steering 180 degrees when turning right and then left. The car skidded on the pavement this happened over a period of 3 months when the temperature was below freezing. After 2 service appointments Bridgewater NJ KIA dealership failed to diagnose the problem . On the 3rd visit they confirmed that the noise emanated from the summer performance tires that caused the tires to skid and caused the noise. Their solution was that storm tires would need to be replace the existing “summer tires”The existing tires are Good Year 255/40R 21. Not only that Good Year does not make snow tires of this size but when I first leased the car I was not told that the car would need snow tires to prevent skidding from snow or icy road conditions. There failure to notify car owners in the northeast of this hazard puts drivers at risk and potential for accidents in cold weather temperatures. Since I have not driven the leased car in below freezing temperatures and risk safety and hazards from driving on these summer tires I believe KIA should be held responsible for failure to notify drivers of this condition. I plan to terminate early the 3 year lease and also withhold payment until KIA acknowledges that they failed to identify this safety hazards and then did not offer to replace these tires to prevent future accidents. These “summer tires” were also Not clearly defined as racing tires with inability to provide adequate tread on icy and snowy road conditions. I am submitting this claim to prevent potential car accidents in driving the car in the northeast were weather conditions are periodic snow and icy conditions.
Well, at first I got the 12 V battery fixed because it wasn’t throwing the code because my 12 V battery wasn’t holding power and then I did get the code and it turned my vehicle into turtle mode where it would not move. This could’ve been very unsafe in the car. I have brought it in now and it has been 20+ days and I have not ha…

Well, at first I got the 12 V battery fixed because it wasn’t throwing the code because my 12 V battery wasn’t holding power and then I did get the code and it turned my vehicle into turtle mode where it would not move. This could’ve been very unsafe in the car. I have brought it in now and it has been 20+ days and I have not had resolution and I have not received the part to fix my car. I have been left as a single mother without another vehicle to use the dealership offered me a vehicle and I was driving that, but it has issues with the Wheel bearing and rotors which at first they told me I would be held liable for driving and then they told me to continue driving it since then now I am renting a vehicle which I cannot afford as I said I am a single mother and I can’t afford $300 a week and then we wait to be reimbursed by Kia they have done nothing to help me and my situation and I am concerned. I have had this car for less than two years. I have less than 24,000 miles on it and by Iowa lemon law it should be resolution into it getting fixed so I am making a formal complaint.

While driving, the vehicle screen showed an electrical warning on the screen. The car went into limp mode and dropped to 25 MPH. 5 minutes later, the screen showed a critical electrical issue and said I needed to pull over as soon as possible. It was towed to a dealership. They found the ICCU is faulty. Because so many EV6's have this problem, it is on national backorder, My concern this vehicle seems to be a safety hazard where it shuts itself down and strands its driver because of faulty parts.
