2023 KIA EV6 Electrical System Problems

Got a Check electrical system error, car reduced speed and 12v battery stopped charging. Car was towed to the dealership and they confirmed that the ICCU needed to be replaced.

My Kia EV6’s ICCU failed while I was driving, leading the car to completely lose power while on a busy street.

While driving, heard a pop and a check electric vehicle system error popped up on the dash. Car was not drivable except for very low speeds shortly after (impacted safety of the drive) until it eventually stopped being able to turn on at all.

Car said there was a 12V low battery danger and said to pull over immediately while driving. After taking it to the dealership, they said my ICCU went out. So they had to replace it. I've read that the ICCU on these cars are notorious for failing and needing replacement.

ICCU FAILURE. Car would not drive

The ICCU that charges the 12V on board battery failed to keep the battery charged and it made my vehicle a paper weight. Had to have it towed to my local Kia dealership to wait 2 weeks for an appt. Hasn’t been repaired yet and I’m sure it won’t be a short wait after they schedule the repair

The vehicle experienced a total power failure resulting in complete inoperability (no start, no unlock, no electrical response). This is the second occurrence within approximately five weeks. The most recent incident occurred after the vehicle was fully charged and driven the day prior. There were no warning lights or messages before the failure. The vehicle was previously inspected by an authorized dealer and a manufacturer service campaign related to the charging/low-voltage system was performed, after which the problem recurred. This condition can strand the driver without warning and poses a safety concern.

First year of ownership rear engine needed to be replaced. The car literally stopped where I was on the road and had to be towed to dealer. It took a month to get the motor replaced. After that, my car stopped while I was leaving my house driving it out of my driveway. There were red warining lights and sounds and then it just suddenly died seconds later. It had to be towed to the dealer. They said it was fixed and that the 12v battery wasnt being charged. Then I was leaving church when my car died on me again. Same issue. Now, the third time in this vehicles 2 years of life, my car died while I was on the highway driving to work in the morning in the passing lane during rush hour. The dash went red and waring lights and sounds with a message get to safety quick check electrical system and it only gave me a few seconds the car suddenly just stopped running and I was coasting on the highway to try to get to safety. I was going 70mph in the passing lane during rush hour, I could not steer to the left to coast off the road because on my left it was just a ditch no side road to stop on, I saw in the right lane a car that was a length or so behind so I cut my wheel straight across the right lane where I coasted to a complete dead stop barely making it to the side of the road. The side of this highway was barely the width of my car so traffic flying next to me was just inches away from my drivers side door.... I called roadside assistance and had it towed to the dealer. They then told me about the recall - which I had already had it into the dealer to fix the last time it was there for this same issue. The car is 2 years old and so far I have had it stop dead in its tracks on me 4 times! I have such stress and anxiety about continuing driving this vehicle as it is completely unsafe! I almost died last week when this happened. My safety and others on the highway that day were at risk. This could have been catastrophic.

My 2023 Kia EV6 experienced a sudden ICCU and 12-volt system failure while traveling approximately 50 mph. Without warning, the vehicle instantly lost propulsion and all electrical power. This included loss of steering assist, braking assist, hazard lights, shift capability (unable to shift into Park), and even the ability to lock the doors. The failure effectively “bricked” the vehicle in motion. I was only able to get the vehicle off the roadway because the road happened to slope downward into a nearby lot. Steering required significant physical effort, the brake pedal went completely hard (“dead”), and the vehicle offered no functional parking brake or Park engagement once stopped. Because I was on a hill, we had to allow the car to roll to the bottom until it met a curb to prevent movement. After power loss, the doors could not be locked at all. This type of unrecoverable electrical failure creates an extreme safety hazard for the driver, passengers, and surrounding traffic. There is no pre-warning and no diagnostic indicator. The ICCU fuse appears to fail spontaneously and renders the vehicle uncontrollable in several critical respects. This is not an isolated issue. ICCU failures have been occurring across the Kia EV6 and Hyundai Ioniq 5/6 platforms for more than three years, including on brand-new 2025 models. The persistence of this defect across multiple model years indicates that the underlying design or component defect has not been resolved by the manufacturer. Given the suddenness of the failure, the total loss of vehicle control systems, and the long history of similar incidents reported by other owners, I am now hesitant to drive the vehicle due to the unpredictable and dangerous nature of the defect.

The vehicle can't be changed with a message "issue with electrical system". The message blinks very fast for 3sec and disappears. I have to turn on and off the car a few time to be able to read the message. The the car lost 12V secondary battery, it only shows 5.5V when measured. car is dead.. Replaced with new battery, car can start again but the car still can't be charged. Is it related to ICCU problem? KIA doesn't show any recall to this problem.

ICCU failure

On several occasions, when traveling over 55mph, once the battery hits a certain threshold (35% or 55% so far) the “power is limited” warning will appear on the dash and the vehicle will lose power. This has not occurred at lower speeds but only at higher speeds, and not every time. This vehicle was purchased so my husband could do his freeway commute, but it is on a remote highway where there is often no shoulder, so it especially dangerous to suddenly lose power with limited ability to safely pull over. On one such occasion, he drove the vehicle straight to Kia for inspection. They said the soonest available appointment was in 2 weeks and because they had no technicians available, they could not run the diagnostic that would allow us to get a rental car in the meantime. They suggested going to a different Kia dealership. We called ahead and they said they could try to see it that day or the next, but when we arrived (with, again, the power failing on the drive to the next dealership), they said we were misinformed and they would have to hold the vehicle for at least a week with no rental option. We have since been unable to use the vehicle for commuting due to its unreliability and incredibly dangerous power failure.

The contact owns a 2023 Kia EV6. The contact stated while attempting to unlock the driver's side door with the remote, the door failed to unlock. The contact manually unlocked the door with the key. In addition, while attempting to start the vehicle, the vehicle failed to start, with the message "12-Volt battery failure" displayed. The vehicle was towed to a local dealer; however, the vehicle was not diagnosed. The vehicle was not repaired. The contact referenced NHTSA Campaign Number: 24V200000 (ELECTRICAL SYSTEM); as a probable cause for failure. The manufacturer was notified of the failure. The approximate failure mileage was 30,000.

Mileage: 30,000

had 3 recalls on ICCU module, each time dealer said everything was OK. Last "repair" was in January. In April, car just "died" nothing worked, could not shift, no acceleration and limited braking, had to call a tow truck to move it as everything was locked up. dealer said ICCU shorted out, 3 week repair time, and this is down from 3 month repair time 2 weeks ago. The only warning we had was a dash message to check electrical system, meanwhile Kia app for car said everything was OK, no problems with any thing. dealer listed faults as, P1A9096 dc converter sensor fault, P1E3716 battery charger V2L low voltage, other low voltage comm codes as well but not listed

The ICCU in my Kia EV6 failed while driving. Thankfully I was not involved in a crash, but my speed was capped at 30 MPH, crawled back home, where the vehicle wouldn't start. I had to get it towed to the service center. All of this besides all recalls and software updates being addressed. There were multiple warning lights that went off during my drive: "Stop vehicle and check power supply" "Check electric vehicle system"

On April 6, 2025, while charging my car my Juicebox tripped a breaker. When I reset it the Juicebox was showing errors and was inoperable. I tried to use my backup charger (Blink) but it tripped a breaker and became inoperable too. I took the car a commercial charger (ChargePoint) and it would not charge the car. Kept getting a “charge interrupted” message. The first Kia dealer I went to did not have a Level 2 charger and could find nothing wrong and refused to help repair the car. The second Kia dealer had a Level 2 and confirmed it would not charge, but Kia would not authorize a warranty fix. That dealer suggested leaving the car for a few days and hope the car generates a fault that Kia will accept to authorize a fix. •What component or system failed or malfunctioned, and is it available for inspection upon request? The Level 2 AC charging no longer works. •How was your safety or the safety of others put at risk? The car tripping 240-volt breakers and making two 240-volt chargers inoperable is concerning. •Has the problem been reproduced or confirmed by a dealer or independent service center? One dealer has confirmed the Level 2 charging no longer works. •Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It was inspected by a Kia service shop •Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? None

I want to disclose this is the 2nd time this has happened. I was on the highway when the system failed. Immediately and drastically forced my car down to 25mph on [XXX] going to Philadelphia in the far left lane with no warning. I had to make it across 3 rows of traffic and ride on the shoulder of the highway until I could find a safe place. One ruining the sport tires on the car and probably messing up suspension since these cars are very sensitive and the highway does have those perforated shoulders. While cars zip past me I am having to figure out how to pull over with no force. None of the functions were working. It was traumatizing. Especially to do it again after 6 months ago the same thing happened. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Integrated Charge Control Unit (ICCU) failed. Charging error appeared on 30 March 2025. Next attempted to drive vehicle on 2 April 2025. Accessory battery suddenly dropped from 12V to 8V. Vehicle displayed "Stop Vehicle and Check Power Supply." Was able to crawl home in "Turtle mode" before tow to dealer. P1A90(96) [0x1A9096] among the Diagnostic Trouble Codes stored. Dealer confirmed ICCU failure and estimates at least one month to repair. SC302 was applied on 13 May 2024 at 5,732 miles. SC327 was applied on 2 Jan 2025 at 10,506 miles. 12V accessory battery is original (sealed lead acid).

On January 27th I was driving home on I-495 in the far left lane going about 70MPH when the electrical warning light came on. Telling me to stop the car and take to the dealership. While I was trying to get over into my far right lane, the car went from 70mph to 25 mph in about 40 seconds! Cars were flying all around me! It was terrifying and incredibly dangerous! The dealership discovered my ICCU had failed. This vehicle has a fatal flaw that is going to get someone killed.

I have received at least two recalls on the ICCU component on my Kia EV6, which were taken to the dealership for repair per the recall. On April 4, 2025, my vehicle displayed the "Check Electric Vehicle Systems" and "Stop vehicle and check power supply" alerts. It had to be towed to the dealership, as it cannot be driven. They called and stated it was related and the part is on back order for the unforeseen future.

ICCU failure. Car was dropped off with Kia and the (second) recall they claimed to have performed did not fix the 12-v battery charging system error. They ordered in a new part, which was on national backorder and they provided no ETA. I had to purchase a replacement vehicle after 30 days of them having the vehicle without making the repair, providing an update, or having given me a loaner. Received message it was fixed after 37 days, but no information whether it is with a new part. Subreddit for the EV6 shows this is a widespread issue that has not been permanently resolved. When the ICCU fails, you are limited to 25mph "limp mode" and will lose ability to move car if 12V battery dies.

While driving my car a warning flashed stating "check electrical vehicle system." Pulled over, contacted Kia of Abilene and asked if we could drive the car to the dealership. While on the phone another warning flashed ""Stop vehicle and check power supply." Attempted to drive car, "Limp mode or turtle mode" occurred and the max speed for the car was 25mph, sudden loss of acceleration. Made it home, which was approximately 2 miles away, and it seems like the 12V battery was draining quickly. Eventually the vehicle stalled at home and became unresponsive, no power. Contacted roadside assistance and the vehicle was towed to Kia of Abilene. All of this occurred March 29th at approximately noon. The dealership finally contacted us today, April 2nd, and notified us it was an ICCU failure and the part wasn't available with no foreseeable time-frame for repair. The car is absolutely inoperable!

ICCU failed at 30,200 miles disabling vehicle on street in front of my house. Date 1/27/2025. Towed to Dealet. Waited 8 wks for repair due to parts back order.

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.

The charging system warning light is on. 2. **Availability for Inspection:** The malfunctioned charging system and associated components are available for inspection upon request. 3. **Safety Risk:** The safety of myself and others is at risk due to the potential for unexpected vehicle breakdowns, especially during charging, and the indication of overheating poses an additional safety concern. 4. **Confirmation by Service Center:** The problem has not yet been confirmed by a dealer or independent service center, but a service appointment has been scheduled to address and diagnose the issues. 5. **Inspections by Others:** The vehicle has not been inspected by the manufacturer, police, insurance representatives, or other third parties at this point. 6. **Warning Lamps or Messages:** The charging system warning light is the primary symptom, appearing alongside extreme range decrease, charging failures, and inconsistent charging speeds. These issues manifested without prior warning. I appreciate your attention to these specific details and look forward to resolving these concerns promptly.

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 randomly. I’ve let the dealer know about this problem but they seem unfamiliar with the issue and don’t have a solution. We’ve tried updating the software and problem still occurs. According to forums this is a common issue with these vehicle but the dealer does not have a concrete solution.

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 5 has the same problem, is receiving a fix which will illuminate the brake lights while using the same 1 pedal driving programming as the Kia EV6. Because the lack of 1 pedal driving brake light warning to following vehicles, I have turned this feature off until the issue has been resolved. I hope NHTSA takes this dangerous situation seriously and provides legislation to force auto manufacturers to adjust the conditions when brake lights must illuminate.

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 (OBC) for Level 2 recharging from 10-100% in 7 hours, which is unachievable due to constant overheating. I have a ChargePoint home flex charger set at 48amps.
