2022 KIA EV6 Electrical System Problems

On April 13, 2024, when I started my vehicle, the instrument cluster immediately flashed the following warning msg surrounded by a flashing red circle: 12V Battery Very Low Stop Safely I turned the vehicle off, waited a few seconds and when I started it again the message did not appear. I contacted KIA USA and received a Recall Inquiry Case #. On April 18th, when I started my vehicle the same 12V Battery Very Low, Stop Safely msg displayed. It did not disappear upon restarting. Within 5 mts ALL the electrics were dead, including the instrument cluster AND the parking/emergency brake control AND the Vehicle Start On/Off button. I am very fortunate I was not driving on the highway when this occurred. Ditto for other drivers. My vehicle had to be towed to my dealer/service center. The tow service jumped the 12V battery and was able to drive it up...

While driving at night under raining conditions with the auto highbeam enable the Kia’s HUD will get so bright at times that will white out the drivers view making nearly impossible to see. Kia’s is refusing the fix the issue because they can’t replicated even with a video I provided and I even found another persons video on YouTube, as well as several owners on a forum complaining about it.

After starting the vehicle and beginning to back out of a parking space, a loud pop was heard from the rear of the vehicle. Immediately, a "Check vehicle electrical system warning" appeared on the dashboard, followed by "Stop vehicle and check power supply". While attempting to drive to a safe location, a continuous warning began to sound along with a dashboard warning to stop immediately. The speed of the vehicle was limited which could have caused an accident when driving on public roads. The vehicle was towed to the dealership where it is waiting for diagnosis. During the tow, the vehicle was unable to move under its own power. The symptoms appear to represent a failure of Integrated Charging Control Unit (ICCU) (NHTSA Campaign Number: 24V200000). There were no warning lamps, messages or other symptoms of the problem prior to the failure.

Heard a loud pop noise as I was driving. Check Electrical System warning immediately flashed on the dash and vehicle slowed down while I was driving. Moments later, vehicle entered "turtle mode" allowing for restricted speeds. Vehicle then flashed error message about 12V battery having low charge. Vehicle continued to reduce maximum speed until it came to a stop minutes later. No previous symptoms and all TSBs and recalls had been performed on the vehicle. Tow truck was necessary to get the vehicle to a dealer. Vehicle currently with the dealer awaiting assessment and diagnostics.

Premature failure (23 months) of the 12 volt battery Dealer unwilling to replace battery under 3-year warranty Vehicle taken to dealership - supposedly submitted to tech support under case# 16248382 (see attached)

12v battery died suddenly, prematurely, and unexpectedly while driving at highway speeds. All vehicle safety functions failed and car immediately lost all power. Was able to pull over safely at which point vehicle shut it self off and would not start again

While driving at normal road speeds, the vehicle suddenly lost all electronics (infotainment, air conditioning, dash). After 2-3 minutes these systems came back online but the car continued to have a warning light for the Lane Keeping system not functioning. This warning now comes on periodically after this incident

While driving my car on March 7th, 2024 around 2:30pm an error message popped up "Stop vehicle and check power supply" and speed of the car was noticeably limited. Thankfully I was able to pull to side of the road and called road side assistance as car was undrivable, the 12 volt battery was completely dead. When tow truck arrived, a jump park was required to put car into neutral in order to get onto tow truck. If this happened in a freeway this could be a risk if we are not able to stop at a safe location. Towing services was able to tow my car to the dealership about 15 minutes away, upon unloading vehicle onto lot, taking an Uber home as no loaners are available, asked the next day about getting car into diagnosis and was told that it would take 2 weeks to get in to...

When driving at 35 mph on level ground, a loud "pop" was heard and the vehicle immediately lost power and warning messages having to do with the 12V system appeared on the instrument panel warning that the car needed to be pulled over in a safe spot and turned off. The vehicle was transported to a local KIA dealer via flatbed and has now been at the dealer for more than 30 day. So far, the 12V battery, the ICCU, the inverter and ICCU fuse have been replaced.

While driving, EV vehicle suddenly lost most of its power. Normal driving on 45 mph street until came to stop light. Would not accelerate over 28 mph upon light changing to green. 12v battery warning light came on.

While driving my car on [XXX] around [XXX] an error message popped up "Stop vehicle and check power supply" and speed of the car started to decline. I could not drive more than 20mph on a main street that had a speed limit of 35 mph. Thankfully I was able to park at a Ralphs in a safe place before the car died. The 12 Volt battery died. If this happened in a freeway this could be a risk if we are not able to stop at a safe location. Towing services was able to tow my car home but I had to keep a portable jumper connected to the car so I can move the car on the flatbed since I couldn't put the car in Neutral for towing. I replaced the 12 Volt battery the next day, but the issue persists and the next available appointment is on...

Charging stops after 10 mins, took to dealership had the update done. Still continue to have problems charing on level 2 charger. Lowered the amps on charger. Lowered the amount fully in recommended by the manufacturer still have the same issue.

12 Battery drains out so fast and so often . Even if it is charged overnight externally . it drains out so fast that after driving some distance and after switching off , it does not come back up and we cannot start the car and have to use a jumper to start the car . My car is car dealer for 2 weeks and they are unable to find fix , though they have opened a ticket with Kia Tech and they have 7 such cars as of today facing the same issue.

The car suddenly lost power and stalled to a max speed of 22mph. The car showed a check electrical system please stop vehicle. This is a known issue with the NHTSA. The car was towed to the nearest Kia dealer - Airport Kia in Naples FL.

Stop vehicle and check power supply light comes on. Car shows error message before battery dies while driving. And wont charge. If on the highway you have a few minutes before your battery completely dies although my battery is 100%

Issue with the car, not charging it was the ICcU module

The vehicle completely lost power while driving. My wife came down a dirt road hill, made a left onto [XXX] in Duxbury, VT, heard a "clunk" from below the car, and experienced total power loss. An error flashed on the screen that read "Critical Battery System" and then, soon after, "Stop Car Immediately." She was able to coast 1/4 mile (downhill) to a school parking lot. The car was towed to a dealership where the dealer replaced the inverter (ICCU) and the paperwork stated "DC/DC Converter input voltage sensor fault." The car had 25,896 miles on it when the incident occurred. The total power loss was extremely dangerous, and we were lucky it did not occur on a highway at a higher speed with more cars in proximity. I see online that NHSTA had previous reports of this issue both with the EV6 and the Hyundai Ioniq. INFORMATION REDACTED PURSUANT...

Was driving to go pick up one of my kids later at night. Was roughly 1/2 mile from home driving about 40 mph when I heard a pop / noise on the rear passenger side. Was unsure if I had rolled over something or what. Shortly after that (few seconds later), the "Check Electrical System" came on. Since I was close to home, I elected to turn around to go home since I could conduct a fairly easy turn around near the sub-division. Before I did that, the car then noted "Limited Power" and came up with the Turtle icon. The speed was restricted to 25 mph. This continued for roughly several hundred feet. At that point, a second warning noting a critical issue came up and the speed was further restricted to 12 mph. I was able to go through the 4-way stop sign, continued to drive under the...

My 2022 EV6 has been experiencing issues with the 12v battery that has resulted in multiple jump starts. Battery was tested by dealer but no issues found. On December 5, the car suddenly lost power and had to be towed to the dealer. Immediately prior to this the "Check Vehicle Electric System" light came on. The warning light came on and the car experienced an immediate loss of power and the died completely. It has been one week and they have yet to diagnose the issue.

Driving South on Route 15 in Gettysburg Area on 11-22-2023 I got a warning message on my dash which read “check electric vehicle system”. The warning disappeared off the dash and we continued to drive a bit further. The warning light illuminated once again and I started to look for a pull off area. Not long after the warning appeared the second time a bigger warning came on the dash and directed me to pull over and stop. We fortunately were able to get into the right lane and pull off the road. We were headed to Northern VA and would have been on a number of multi-lane roads where if a dead vehicle is stranded in high traffic area with speeds exceeding 60 to 80 miles per hour could have resulted in a catastrophe with a car that just goes dead. Remember there is no warning except for the...

The driver's side USB-A wiring harness repeatedly (though intermittently) drops connection between a properly connected iPhone and the native infotainment system, causing a "drop-out" of Apple CarPlay connectivity. The safety concerns associated with this are most acute when using Apple CarPlay-based navigation systems, as the native infotainment system stops displaying Apple Car-Play navigation, and begins searching for a USB-A connection with display "Reading USB." This sometimes remedies itself, with return to Apple CarPlay display but often requires physical reconnection of the USB-A cable. This level of manual manipulation of the infotainment system has caused me to lose navigation capabilities mid-trip and frequently takes my attention away from safely navigating the vehicle, especially when in urban traffic. The problem is persistent across multiple phones, multiple cables (including brand new Apple-branded cables), and other USB-A hardware external to the vehicle's infotainment system. The problem is well documented in multiple online owners' forums...

While driving in a major thoroughfare, a red warning came on to check the electrical system, and that propulsion power may be limited. We pulled over to a parking area and consulted the manual. It suggested turning the engine off and back on again - we did so, but the warning remained. We determined that we were 2-4mi from our Kia dealer. Based on the manual information, we believed we would be able to drive at a slow speed and selected a route towards the dealer that avoided the highway. However then the 'turtle' warning light came on and we we were reduced to walking pace. We pulled into a side road, but were unable to pull over completely before we lost all motion. We activated the warning lights, but after a minute or so there was not even sufficient power for those. This was a rainy day with not...

The vehicle throws a "charge interrupted" error on any Level 2 AC chargers and stops charging within few minutes of starting charge. The charging occurs only for 10~15minutes and immediately stops. The issue has been persistent since 3-4 months now and consistent on every charging session. I have to unplug and replug the charger multiple times to be able to complete charging. This also happened to me on a DCFC 150kW charger as well.

Getting check vehicle electrical system warning. Dealer does not read any error Getting multiple charging error faults, dealer does not read an error

car stopped and will not start. 2nd occurrence. 09-25-23 and 10-17-23

The car will cannot be charge as per advertised. It's stop charging after 45 min. and keeps repeating. Took the vehicle to dealership and they cannot solve the problem. I also wrote a letter to Kia of America via certified mail but no respond.

There is a component, the ICCU, that is failing in a number of early cars. Who knows about the later ones? The 12v battery drains and the car won’t start. If the use is lucky, a jump start will get it to run enough to get to the dealer. Otherwise, a tow is in order. This can happen while the car is under way as well. Look at the Reddit ev6 forum and the Facebook EV6/EV9 forum. There are many stories about this problem.

I was driving home when I heard a loud pop in the back of the car then warning symbols pop saying the there is a issue with electrical system. Then it told me to pull of the road due to low power. I've been reading around heard about the iccu not charging the 12v battery while driving and lost all function when it dies.

sometimes vehicle is not charging at 6.6Kw charging. it says unable to connect/not charging. I tried multiple times and multiple locations. Also, I informed the dealer (Kia Fremont) and they are keeping my vehicle from last 2 weeks and there is no communication about the status. [XXX] vin no. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When car is on HDA mode. Drive assist. And speed under 20 miles on Highway. Car make sudden stops and it is also called ghost stop. Very dangerous and will likely to cause rear end collision.

Car 12v battery keep on dying after car is only one years old. Kia can not figure out why. I have to carry an emergency battery jumper with me at all times. This is an electric vehicle and when 12v battery dies. Vehicle loose all power.

I continually have issues with the car not charging. I have taken it to the dealership and they "update the software" but I continue to have issues where my car only charges 10-15% at a time and continues to give me an alert "charge interrupted" but it does not tell me WHY the charge has been interrupted. I will set it to charge overnight but then wake up ready to go to work and my car only has 20% charge and I can't make my commute. I've had the same problem at public chargers. However, my partner has an electric Ford Mustang and his car has had no problems charging at home. I would say for the first 9 months of ownership this was not a problem with my EV6 it only began in the last 3-4 months but it happens almost every time I plug in.

Just like the Hyundai Ionic 5 issue with power loss, my Kia EV6 which has the exact same underlying system (e-gmp); I heard a loud pop followed by my vehicle immediately informing me to stop driving and pull over. It has since been in hobble or "turtle" mode and will not let me drive it for more than 1 minute before insisting I pull over. It has since been towed to the local Kia dealership.

On SEPT.8, 2023 The car was charging and then it stopped charging. There was no warning or indications. All power failed and the EV is now inoperable.

2022 EV6 Wind. For the first 10 months i had absolutely no issues charging the car at home. The car went in to the dealer in mid august for a number of service bulletins. Since those changes, the car no longer accepts level 2 charging at the 48amp speed that it is advertised at and documented to provide. The dealership is not capable of replicating it, because they only have a 32 amp charger, which is significantly less powerful. It is my understanding that this is a heat issue which makes me nervous about a fire. I can turn the charger down very low, but that defeats the purpose of why I bought this car as faster speed charging was one of its selling points.

An error message started flashing on the dashboard. The car came to a crawl was able to turn off to a side road where the car shut down. Had to call roadside assistant and have the car towed to the nearest Kia dealership Two days later was told the iccu had burned out and there was no ETA on a part to fix the problem.

To the questions listed: 1) For the last number of months the car will not fully charge when using a Level 2 charger (note: it will charge using a Level 3 charger). When charging I will get a message that "Charge Interrupted". When I go out to the car the charging has in fact stopped, and the charging cable connector is very hot to the touch. 2) In addition to the inconvenience, I worry the car is a fire hazard putting my family at risk. 3) The Kia dealers have not been able to replicate the problem and insist it is a problem with my charger at home. (Note: I have tested my charging unit on my son's Nissan Leaf and it works fine.) Note: they did apply the "Voluntary Service Campaign" however that did not fix the problem. 4) The car has not been inspected by anyone other then...

Car has a unresolved ICCU failure, which means the battery cannot be charged. Car is stuck in dealer for 6 months with the same issue. Meanwhile, I pay car payments.

2022 EV6 First Edition. Vehicle no longer accepts level 2 charging at the 11kWh window stick advertised speed. Providing car with any more than 9kwh and the charging port gets very hot and car will stop charging. Dealer is aware of the issue but as of now is unable to diagnose as none of their dealerships have power supplies that exceed 7kwh.

12-volt battery is not being properly charged while driving. once resulting in loss of power while moving (thankfully still in our driveway) requiring a jump start, and twice when parked which forced us to have to break into (airbag the door) the vehicle to get the trunk open and jump start. It seems to lose 12-volt battery charge if not driving for a few days requiring us to leave it unlocked if we are not using it over the weekend for example. There have been no warning indicators or other warning prior to this occurring. I was in an accident in February and my vehicle was in the shop for a month. I lost contact via my app twice so I assumed the 12v battery died while they had my car, but they didn't mention the issue upon returning the car to me.

The contact owns a 2022 Kia EV6. The contact stated that the vehicle was purchased new; however, upon attempting to unlock the vehicle to drive a week later, the vehicle failed to unlock. The vehicle was towed to the dealer, where the battery was replaced; however, the failure recurred a year later. The contact stated while driving 40 MPH, a message advising to pull over and to immediately stop the vehicle was displayed. The contact veered to the side of the road. The vehicle was towed to the dealer, where it was diagnosed that unknown parts needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. Additionally, the contact sent requested documentation to the manufacturer through mail. The failure mileage was approximately 87.

The vehicle is repeatedly shutting down its charging cycle during charging sessions. I am always getting “charging session interrupted” notifications.

The 12V battery on my Kia EV6 has died 5 times (May 9, May 23, Jun 18, July 3, July 5 2023). I bought the car in March 2022 and there were no issues until May 2023. Twice the 12V died when parked at home with the Lithium battery at 80% charge, twice when my wife was out and parked and the last time at the 'Serramonte Kia' dealership in Daly City, CA. It required us to call Kia Roadside assistance to jump start the car. It was reported to Kia all 4 times that it happened to us. They recharged the car and when it finally died at the dealership, they replaced the 12V battery. I suspect that it's going to happen again because there's a fundamental problem with the ICCU which prevents the Lithium battery from charging the 12V. I have read that it's already been reported to...

The issue is essentially EXACTLY like this article: https://www.caranddriver.com/news/a44272155/2022-hyundai-ioniq-5-nhtsa-investigation/ We heard a semi-loud pop that appeared to come from the rear of the vehicle. Approximately 5-15 seconds later, we got a notice that the electric system needed to be diagnosed. We were only a block from the house, traveling at low speeds, and did not experience a complete loss of power. However, the system started giving additional alerts (I do not remember the exact phrasing) related to stopping the vehicle immediately.

On 5 May 2023 our 2022 Kia EV6 WIND AWD Automatic vehicle (~11,200 miles on the odometer) was being driven under normal conditions at approximately 30 mph in city traffic when the car lost motive power and a dashboard alerts appeared stating "stop vehicle and check power supply" and "check electrical vehicle system." The driver complied but the shutdown occurred on a heavily trafficked road and put the driver and other travelers at risk and caused the driver considerable distress. The incident was reported to the dealer and manufacturer via the Kia Access app, and the car was towed to the nearest Kia dealer and service center on May 8. The dealer diagnosed the problem as caused by a defective ICCU (a part of the electrical powertrain control system) requiring replacement. As of 12 July 2023, Kia has not provided a replacement part and it remains on backorder with no...

The contact owns a 2022 Kia EV6. The contact stated while driving 35 MPH, the vehicle shut off and lost motive power. The vehicle rebooted and the message "Critical Electrical Failure" and "Stop Vehicle” was displayed. The low voltage message was also displayed. The contact was unable to stop the vehicle or restart the vehicle. The vehicle came to a complete stop independently. The vehicle was towed to the dealer for a diagnostic test however, no failure was found. The contact was informed that the vehicle needed to be diagnosed by a technician. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was 11,000.

HAD JUST CHARGED THE VEHICLE AT A LEVEL 3 CHARGER, RECEIVED BATTERY FAILURE WARNINGS ON THE DASHBOARD, BY THE NEXT MORNING THE CAR HAD LOST MOTIVE POWER DOWN TO 12 MPH MAXIMUM. THIS OCCURRED JUNE 19, 2023. THE CAR HAS BEEN AT THE DEALER EVER SINCE, WHERE THEY ADVISE THAT THERE ARE NO ICCU REPLACEMENT MODULES IN THE USA AS THEY ARE BACK ORDERED. THE DEALER IS NORTHSTAR KIA IN QUEENS, NY.

During Level 2, 48 amp charging the car continually stops and starts charging roughly every five minutes. After contacting the charging maker, their diagnostic showed nothing wrong with the charger or incoming power, and that the car was stopping the charge. My Kia dealer states it is a problem with the onboard charger. However, Kia support doesn’t seem to acknowledge it. I have seen multiple reports of this is happening including a potential lawsuit, so I’m reporting this as an issue as well.

ICCU or 12v system has failed and car died mid drive on the road. Car is currently at the dealership for repairs. With complete electrical failure the vehicle reduced speed and stopped on it's own. This happened at night and I didn't have lights in or on the car to see. Additionally, I was unable to activate emergency lights and put on hazards. The dealership is struggling to diagnose the cause of the issue. The car dying was proceeded by a 12v battery light indicator and the turtle light saying it was reducing power. This was followed by a flashing "pull over vehicle and stop now" message.

Vehicle repeatedly interrupt its own charging, no error codes are surfaced. The charger(EVSE)is in proper working order, confirmed with other cars, the area around the plug gets very warm but not alarmingly so? The issue developed after many months of error free charging. The issue is non limited to a single EVSE, it seems to be avoidable by greatly reducing charging rate.
