2023 KIA EV6

These are unverified consumer reports filed with NHTSA, shown as submitted.

• 12/27/2025· POWER TRAIN,ENGINE,FUEL/PROPULSION SYSTEM

  I am submitting this as a supplemental statement to my existing NHTSA safety complaint regarding my electric vehicle, KIA EV6, 2023 model. Since my original filing, the vehicle has now experienced loss of power / loss of propulsion a total of three times. These incidents occur without warning, are unpredictable, and render the vehicle unsafe to operate. The vehicle can suddenly lose motive power, creating a serious risk of collision, particularly in traffic or at speed. The manufacturer and authorized dealership have been unable to identify the root cause or permanently repair the defect. Dealer documentation reflects that the issue “cannot be replicated,” and no corrective action beyond temporary battery charging or system reset has been performed. No explanation has been provided as to why the power loss occurred or how it will be prevented from recurring. Because the defect is intermittent and safety-critical, I no longer feel safe driving this vehicle and have stopped operating it entirely. A reasonable consumer would consider repeated, unexplained loss of propulsion to present an unreasonable risk to safety. I am submitting this update so NHTSA is aware that: The defect is recurrent (three incidents) The condition remains unresolved The vehicle is unsafe for continued use I respectfully request that NHTSA review this matter for potential investigation, as loss of propulsion in an electric vehicle poses a serious safety hazard to the driver and others on the road. Thank you for your attention to this safety concern. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

  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.

  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

• 12/22/2023· ELECTRICAL SYSTEM

  Hello NHTSA, I hope this message finds you well. I would like to provide specific details regarding the issues with my car as per your guidelines: 1. **Failed Component or System:** The charging system has malfunctioned, leading to extreme range decrease, constant charging failures, inconsistent charging speeds, and signs of overheating. 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.

  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.

  The "trial period" of the Kia Connect ended. It was my understanding convenience features would be turned off. However, safety features such as the voice navigation (navigation still works, but you must type in the destination, which is dangerous), voice to text, and who knows what else, has been turned off. I believe this should be addressed.

  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.

• 12/08/2025· STEERING,ELECTRICAL SYSTEM,SERVICE BRAKES

  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.

• 11/19/2024· VEHICLE SPEED CONTROL

  While driving with the power liftgate partially open, I experienced an inability to accelerate after coming to a stop. I pressed the accelerator and the car rolled gently forward into an intersection at a speed less than 2MPH. A warning displayed on the dash that I needed to close the liftgate before the vehicle would operate correctly, which was impossible because I was in the middle of an intersection with a large chair blocking the liftgate from closing. I was able to restore functionality by turning the car off and turning it back on. Prior to this, there were audible and visual alarms about the open liftgate after each stop. These alarms are described in the manual, which instructs the driver to close the liftgate when the alarms sound. However, driving with a liftgate open is a common use for an small SUV when hauling large or long objects, and contravenes no laws when done properly and safely. The manual does not state, so I did not anticipate, that the vehicle would enter a "limp mode" if I continued to ignore the alarms. Being unexpectedly unable to accelerate is a dangerous behavior, especially if you are in the position to make a left turn across traffic and the car goes into limp mode with cars oncoming. I consider this a safety concern because 1) driving with the liftgate open is not an inherently unsafe activity that warrants disabling the vehicle, and 2) the manual fails to state that the driver might experience sudden loss of ability to accelerate with the liftgate open.

  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.

  No abrasion, curb marks, track use or drifting (I'm 75 years old). Dealer service declined rotating the tires because mounting this one on the front could increase hazard in event of failure.

  Vehicle does not charge at the full 11 kW it's rated for on a level 2 EVSE. It gets charge interrupted. I've had the SC311 installed which causes the car to lower the charging rate automatically instead of just dropping charge. But I still can't get the full charge rate. This occurs on my home level 2 EVSE, on each of the 12 level 2 EVSE ports I use at work, and out in town. The charging port gets extremely hot when charging and is not designed to pass the full 50 amps it's rated for. It struggles at anything over 25 amps. The extreme temperatures of the charging port can cause a fire or burns to people. The car needs to be recalled and the J1772 charging port and sensors needs to be replaced. This complaint is very common in the various EV6 owner's forums.

  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.

• 09/08/2025· TIRES

  I was driving my Kia EV6 2023 on I-110 in California when the driver rear tire suffered an instantaneous deflation. I was driving at or slightly below the 65mph speed limit, there was traffic in front and to the rear of me, the road surface was excellent. The tires had 11556 miles of use and were operating at the correct pressures as the vehicle has a tire monitoring system. The ambient air temperature was circa 76F. I was able to exit the freeway with some difficulty. The tire was a Continental Cross Contact 255-45 R20. I have been driving for nearly 60 years, had a wide range of cars and tires and never experienced an incident like that described which has all the indications of a product defect.

• 09/07/2024· ELECTRICAL SYSTEM

  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)

  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.

  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.

  The brake lights illuminate too early and often under [even very] gentle deceleration. My '23 EV6 GT is driven primarily in Level 1 (minimal) regenerative braking mode and the threshold for brake light activation clearly is far too low. The appearance of "riding the brakes" is dangerous because those who follow are not alerted when the driver transitions from [essentially] coasting to actually hitting the brakes. Also, at least in my mid-Atlantic suburban area, even the appearance of "brake checking" other drivers incites road rage, which I experience most days, especially when using cruise control, unless driving with regenerative braking disabled (Level 0). SC273 was necessary and prudent because the brake lights failed to illuminate under significant deceleration, confusing those who follow. SA541 was necessary and prudent because the brake lights illuminated inconsistently on uneven road surfaces, confusing those who follow. Another VCU software logic upgrade is necessary and prudent because the brake lights fail to distinguish between [essentially] coasting vs. significant deceleration, confusing those who follow, and potentially (demonstrably!) inciting road rage.

  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.

  While using I-Pedal mode the brake lights do not engage unless fully off of the accelerator. Even a large deceleration force does not engage any of the brake lights when coming to a full stop quickly. This is very dangerous as drivers behind cannot tell you are decelerating quickly.

  I do not yet know if the recalled part is defective. The dealer asked me to bring in the car for inspection and if the recalled part is defective then the dealer would order the part and I would be required to bring the car in again to have the part replaced. This requirement of having the customer return to have a defective part repaired puts the customer in the position of having to drive the car in a defective condition that could cause serious injury, whereas if the dealer carried the defective part in inventory this would not be necessary. Kia America will not let the dealer order the part unless it is first diagnosed as defective. In view of the fact that the issue is not attributable to the customer's care or use of the car, rather to the manufacture of it, the dealer's convenience should take second seat to the customer's safety and convenience.

  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"

  Component/System Failure: The i-Pedal feature in the Kia EV6, designed for one-pedal driving through regenerative braking, consistently fails to stay engaged. This component is available for inspection upon request. Safety Risk:The erratic behavior of the i-Pedal function poses a significant safety risk. When the i-Pedal mode disengages unexpectedly, drivers must abruptly switch to using traditional brakes. This sudden transition increases the likelihood of delayed reactions and potential accidents, especially in heavy traffic or complex driving situations. Problem Reproduction/Confirmation: The problem has been widely reported by multiple users on forums and confirmed through personal experience. It has been noted that the i-Pedal mode disengages when the vehicle is stationary or when the battery is fully charged. Inspection by Authorities: The vehicle has been inspected by a dealer, but the issue persists due to a lack of awareness or understanding of the i-Pedal system among service personnel. No inspections by the manufacturer, police, or insurance representatives have occurred yet. Warning Lamps/Messages: There are no warning lamps or error messages indicating the malfunction of the i-Pedal feature. The issue is typically observed when the vehicle unexpectedly exits i-Pedal mode, requiring the driver to manually re-engage it using the steering wheel paddles. Assessment of the Incident:The inconsistency in the i-Pedal system's engagement appears to result from potential software bugs, sensor malfunctions, or design flaws in the regenerative braking system. This unreliability significantly impacts daily driving safety and efficiency. Recommendation 1. Software Update: Kia should release a firmware update to ensure the i-Pedal mode remains stable and reliable under all driving conditions and even after vehicle is turned off and back on.

  ICCU failure, a well known issue with these cars.

  Iccu failure with Kia ev6. Unreal that this car has not had a recall yet. It is totally unacceptable that this car can at any time fail. Car will not start and shut down while I was driving. Luckily I was beginning to park when it happened

  The ICCU unit failed. The message "Check Electrical System" appeared on the instrument cluster. Low-voltage battery voltage was 12.0V and vehicle speed was limited to 60 mph. Maximum speed was gradually reduced to 30 mph over a period of 40 minutes (voltage was 11.5 V) with minimal 12V loads. I pulled over and called a tow truck to the nearest service center. Kia confirmed the ICCU was defective and replaced the part under warranty.
