2023 KIA EV6 Electrical System Problems

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...

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.

12v battery failure. Unable to start car, needing tow or jump to get to dealer for repair. 2/17/2024 towed 2/24/2024- jumped by AAA couldn't get appointment till 3/11

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

This issue has been persistent for at least 4 times a week for the past 4 months since getting the vehicle. The issue starts right after starting and driving the vehicle within about 5 mins after start-up the speakers start making an EXTREMELY loud/piercing abnormal sound while the vehicle is driving or even parked. I immediately have to pull over (while the loud noise is still happening) and turn the car on and over several time hoping the noise stops. The noise is extremely loud and abnormal static noise the entire time the issue occurs. The times it’s happened it would not stop for at least 15 mins, I try turning the car on/off and still won’t stop. This happens randomly and I am forced to pull over immediately while the extremely loud static noise is piercing my ears. There are no warnings prior to the issue occurring, just happens...

When charging with L2 40A home charger vehicle gives a charging failed error. I live in Arizona where since the temperature has gone above 90 degrees in June the issue started. It will charge for a few minutes than fault. I have used this charger on other vehicles without issue. I need to change the vehicles charging settings ro reduced charging current for it to charge without error but this can take twice as long to charge on the reduced settings. I am convinced this is temperature related and the vehicle cannot charge high current in such extreme heat.

When using 1 pedal driving, it isn't necessary to use the brake pedal to stop the EV. The EV6 will only illuminate the brake lights when the accelerator pedal is completely released, or when the brake pedal is depressed. Since using 1 pedal driving does not require depressing the brake pedal to stop, the following vehicle has no indication or warning that the EV6 is stopping. I have experienced several instances of near rear-end collisions because of this dangerous issue with the Kia EV6. I emailed Kia asking if they were going to offer an OTA fix and this is their reply, " Dear [XXX], Hello, This email is to let you know that as of now we are not aware of any updates coming out for this feature. Your complaint will remain on file here within Kia for review. Sincerely, Kia America. Curiously Kia's parent company Hyundai, whose Ionic...

I purchased my EV6 in April 2023, after 2 months, my charging abruptly stops, I will restart it and it fails minutes later. I have taken the car to the dealership 2x and they are unable to find the cause, I did further research and found an update that was applied on the second visit. This did not resolve the issue. I am having to drop the charging level down to "reduced" to get by. There are no warning messages on the dash or on the computer, at least none that Kia could find. There isn't a recall for this either. My concern is the safety of the car, due to the high voltage used to charge the car.

This car advertises that it is capable of fast charging on a level 2 charger up to 50amp. I purchased a level 2 charger capable of 50amps, but it causes the EV6 to overheat and stop charging. The dealership installed TSB ELE-283 but this does not fix the problem and is not an acceptable fix. I have owned this car 5 months, and it has been to the dealership service department 3 times for failing to charge. Kia has admitted that their dealerships don’t have the capacity to charge at the higher speeds, so they cannot replicate the issue and just keep giving me my faulty car back. While the expectation is that the car can charge at 48 or 50 amps, typically it fails at 40 amps and users are forced to reduce to 36 amps, which is not what was advertised. The Kia website advertises 11kW on-board charger...
