2023 Kia EV6 electrical complaints
Page 4 of 5: complaints 71 to 100 of 105, newest first, as owners wrote them.
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.
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.

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 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.
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.
12 volt battery failed to recharge
Rear seat 120 ac voltage outlet indicates an open ground when utilizing an outlet tester. I believe this risks a electrical shock injury to the user. The dealer service department states all is well since a device plugged in powers up. It seams that the dealer service department does not have the requisite knowledge in dealing with household voltages and is not equipped with the appropriate test equipment.
I was pulling into a mall parking lot. The vehicle started beeping and popped up a message on the dash saying "stop vehicle and check power supply". The vehicle slowed to maximum 25 miles per hour. The battery died completely the vehicle has no power at all and cannot be driven or even moved off the roadway - there is no way to even get it into neutral now. The dealership wont look at the vehicle for 2-3 weeks even though it is only 1 year old. I did pull off the road before all this happened but it was so sudden and happened so quickly that I was very aware of how dangerous this could have been had I not heeded that warning immediately.
My Kia EV6, AWD Wind has the exact problem described in this Ionic 5 video, [XXX] , which addresses your TSB 24-EV-003H. It appears my EV6 uses the same electric oil pump (EOP) as the Ionic 5, so I am not sure why the EV6 was not included in your TSB? The first 14 months I owned my car, I loved it, then in June after I started driving for 45 to 60 mins, the car ride started becoming rough or unsmooth. After researching it on the Internet and purchasing some diagnostic tools, I figured out, that when I start driving the car there is a demand signal for the EOP but the pump has no rpm, no torque and no DC current. Depending on driving conditions, it appears the rear motor stops propelling the car when it reaches 190 to 205 degrees and the front motor kicks in to do all the propulsion. Under the front motor propulsion, the car has a definite “lag” in responsiveness which I consider extremely unsafe as I expect to get an instantaneous response when I step on the accelerator not a lethargic response with no “zip”. It is similar to the difference between a turbojet engine and a turbofan engine. It has been to my Kia dealership’s service dept where they told me they duplicated the the switch from the rear to the front motor but after talking to Kia this condition was “normal” as the computer calculated this was the most efficient operation of the car I said that was BS and asked them if they checked the oil pump and was told yes. Bottom line, it’s the same EOP as the Ionic 5 and the EV6 has the same problems with it except there is no displayed fault code so Kia fails to acknowledge the problem. Also, based on what I see when the motors switch, the on board screen display shows the front motor with 5-7 bars of whatever the measurement is and the rear motor has only 1 or 0 bars but the OBD data shows both motors with the same rpm? Three EV6 problems: EOP inoperative, no fault code, data disconnect (OBD vs displayed data). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX], I went to charge the car at the Katy Mills location in Katy Texas. After fully charging the car, I went to visit my sister's house to visit. When I returned to the car it had completely shut down. I would not start and none of the electric components worked. I had to have the car towed to Westside Kia, who offered no assistance with a loaner car. I called three days later and was informed by Sabestian that the ICCU had blown out and the part is on National back order. There are three people in my home who are disabled and two young children who has to be driven to school. Upon further research about this ICCU unit, there is a total of 48,323 Affected Units and Kia Corporate has offered no assistance in buying this car back although it is still under the manufacturer warranty. If anyone can assist me with information on how to best handle this situation, I would highly appreciate it. So far I have paid over 2,000 in car rental fees, in lieu of my medical situation.

Vehicle lost its power while trying to park. It could not be locked either. This is the second time this has happened. The first time, dealership said they replaced the auxiliary battery. When it got towed the second time, the dealership said, we only recharged the aux battery during the last complaint! Now, the dealership does not have anyone who can look into this issue for one week. Added to that, they do not have any loaner cars either! The car has 10,523 miles on it now. Car had 8000 miles during the first incident. We feel this is dangerous, unacceptable quality and not to mention, unbecoming of a vehicle brand not to give us a loaner car and expect us to wait a minimum of 10 days to figure out the problem.
2023 EV6 - The car gave a warning to check the electrical system. Called the dealer and they said to drive it to them. One minute later the tortuous symbol came on as well as the 12v battery. The car had no power even when the accelerator was pressed fully. Parked the car and the dash shut down. Towed the car to the closest Kia dealer and they diagnosed it as a faulty ICCU and Main Fuse. Only ONE in the entire United States. Unknown date of fix. Left me stranded as well as in a dangerous position.
Factory installed 12V battery died at about a year's ownership and about 22,000 miles, leaving me stranded in a remote area. I was fortunate to have a jump start pack to get home. I had the battery tested at an auto parts store and it failed. I replaced it with a lithium car battery with a built-in monitoring system that can be read from the phone. The car routinely runs the 12V battery down to about 50% while driving, then charges it up to 100%. This cycling behavior destroys 12V batteries.The monitor built-in to my lithium 12 V battery shows 26 complete charge/discharge cycles in the 2 months it's been installed. Cars should not fully discharge the 12V battery when being driven
Vehicle does not reliably handle the 12V battery well. Many times, I see it sitting at 12.8 VDC when driving the vehicle. On a ICE vehicle, the charging voltage is close to 14V when running/driving. On 3 separate occasions, when I tried to "start" the EV6, the 12V battery was too dead to allow the car to be started. Basically stranded. This can be life threatening if this occurs in frigid temps. Or a hazard to traffic if/when the car tells you to "pull over safely, immediately". OK, I can "block the box" because my car died??? Kia and Hyundai need to address this issue that's common to their recent "luxury" EVs. With all the high-tech these cars have, why can't it manage the charge-state of the 12V battery? Tesla vehicles do not have this issue (I believe). Tesla EVs do "lose" their 12V battery over time, but that is similar to the 12V battery that eventually dies in a regular ICE vehicle. This 3rd time that this occurred, I called 800-KIA and had the car towed. So far, "they cannot reproduce the problem".
Car was in garage and tried to start it. Would not start, although the dash lit up briefly and it showed the main EV battery was at 49%. Message then appeared on dash stating that 12 volt battery was discharged. Car then went completely dead electrically. No electrical power of any kind. Had car towed to KIA dealership and they have so far not been able to fix it. It is under warranty. There is a Kia recall, SC302, which seems to fit the problem with my car, but my specific VIN number is not on the recall list. The dealership ran diagnostics and said 12volt battery passed their tests. I suspect maybe a ICCU problem and that my car should be on the recall list, but is not.
For about 6 weeks, after driving the car for more than 2 minutes, turning the car off and then coming back into the car within several hours (like when picking up kids from daycare, grocery shopping, going to restaurant, etc) results in no sound regardless of source, including ALL alert sounds for collision, blind spot, cross traffic, literally any and all sounds inside the car. Resetting the infotainment using the small reset button does not work. Unplugging and then replugging any fuses does not work. The only solution is after the car is turned off for several, typically 4 or more, hours. This is incredibly dangerous not just for the alerts, but because it renders Bluetooth calls impossible, resulting in having to use the phone manually while driving after trying to disconnect the Bluetooth connection. Others online have reported needing the amp replaced in order to solve the problem.
Issues with 12v battery dying with only 8,000 miles on vehicle. Knowing Kia requests an all day testing of the battery prior to replacing the 12v, I replaced it with a higher quality one. My car still did not start not long after that. Lots of folks online with similar issue and feels like Kia needs to do a recall with a known good fix. Blame put on 3rd party apps when it’s a design flaw.

El vehículo desde las 500 millas comenzó a encender el aviso de problema en sistema eléctrico , como era intermitente no pudieron arreglarlo , luego el sistema de entretenimiento se apagaba solo , la batería se sobrecalentaba mucho estando apagado y estacionado , por último dejó de recargar la batería , me dejó tirado en medio de la autopista , casi me accidento , lleva dos meses en el concesionario y aún no encuentran el problema
The vehicle gave the warning to check the electrical system, as a result the battery cannot be recharged.It only accepted the charger for two minutes and then disconnected, now it only says it could not be recharged. They reprogramed it from the MOTOR AMBAR distributor but they did not find the it fails. Now i have a decorative vehicle in my garage and no one knows how to fix it.What if the electrical problem causes a fire in my house ?
1) AC Compressor and components. 2) Puts me at a health risk because of no AC it’s hot outside. I shouldn’t have these issues with a 2023 vehicle. 3) My vehicle has been sitting at the dealership since June 12th and no one has touched it. 4) The dealership “claims they are just extremely behind, however I think they don’t have anyone that knows how to work on EV’s! 5) Coincidentally, after KIA sent out an over the air update in May is when this started to happen. A loud high pitched voice came from under the hood when the AC was “supposed” to have cut on. They said a supplemental update might fix it, however it didn’t. Now we are two months later with the vehicle sitting in the same spot and hasn’t moved…
The car starts charging on my level 2 home charger then after about 10-20 min will stop and send me a message saying charging interrupted and will stop charging. I have taken it in to the dealership and they say they can see the code but that they did the recalls for it and it should be fixed. It is not and keeps happening. I am taking it back to the dealer tomorrow so they can look at it again
