2023 Kia EV6 owner complaints

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

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

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

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 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.

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 ?

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 go

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

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.

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.

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.

Car vibrated to degree it was hard to control. Initial tire balancing did not fix the issue. The tire was removed from the rim and a separated balled-up foam tire liner was found and removed. My concern is if this happens again in one of the other tires and causes an accident.

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.

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.

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.

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 mov

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 comm
