2024 KIA EV6 Problems & Complaints

Whike driving down the street, the car lost power despite being charged to 95%. An alert went off on screen stating an electric system issue and then stopped in the middle of the road. Between the warning showing up, and car losing full power was less than a minute. There was no opportunity to pull over safely and the car was stuck in the middle of the street until a tow truck was able to come. Police had to direct traffic as it was blocking the only lane on a busy street.

Multiple times the 12V battery has died without warning. Once in driveway while engine was charged to 93%, once while parked at work parking lot at charging station. Both times the car had to be jumped by AAA and driven to the dealership where it sat for 7 days each time with NO diagnosis, no loaner, no rental, and no transport. Finally after the second time, the dealership replaced the 12V battery but still did not give any diagnosis whether this was the ICCU or not. I have complained to KIA Motor Corporation who have advanced my complaint however they have eventually dismissed my complaint. They cannot answer me whether they believe this car is safe. They cannot stand by the safety of this car. They have not acknowledged that this is a safety problem and that other motorists have had similar battery failures while driving on the highway and in other unsafe areas.

I was driving and got an error that there was a problem with the electrical system. It then gave me a n error of "Stop vehicle and check power supply". It's an electrical vehicle and I am not able to charge it now.

ICCU and fuse failed while I was driving in the snow. Heard a thunk in the rear and Check electrical system came on screen. I had power to be able to drive the car home a few miles. SC327 recall software fix had been applied already over a month before this, but during that recall I was not advised to replace the ICCU. It failed right after putting the car into Snow mode. Was driving 20mph, auto regen braking on. Stop vehicle and check power supply message came on. Original 12v battery still on the car, never had issues with that. Most charging done at 9.6 kW level 2. Dealership reproduced the problem and has now replaced the ICCU and fuse.

I was coming home from work on 1/13/2025 and got an alert. a red circle saying pull over and check the electrical system. when i pulled over the best i could the car went dark. i called Kia for road assistance and they dispatched a tow to the dealer. the next day the dealer called and told me the ICCU needs to be changed and arranged a loaner car for me. The Dealer has been very helpful throughout this ordeal thus far.

I am reporting suspected odometer fraud and misreported mileage/VIN/title data by Greenway Kia North (Longwood, FL) involving my 2024 Kia EV6 GT-Line (VIN: [XXX] ) and my 2017 Audi Q5 trade-in. These actions appear to violate the Federal Odometer Act (49 U.S.C. § 32705 and 327 and Florida title/odometer laws. After attempts to resolve the matter, I issued a rescission and statutory-demand notice on Nov. 8; the dealer provided no adequate response. Title/Registration Misrepresentation: My Audi Q5 (dark blue) was submitted to FLHSMV as “Monsoon Gray.” The EV6 (Aurora Black Pearl) was submitted as “Blue.” I verbally corrected both errors at signing; the dealer ignored them, and the false data was transmitted to the State and later reported through Carfax. This indicates intentional or reckless submission, not clerical error. Odometer Fraud: The dealer certified 131 miles on the Odometer Disclosure Statement, though I informed them the mileage was higher. Post-purchase evidence shows the certification was false. Documented travel from Dec 29–Jan 4 totals ~546 miles. Charging records (49.2 kWh on Dec 30; 63 kWh on Jan 2) indicate regular use inconsistent with a 131-mile vehicle. On Jan 4, the dashboard displayed 965 miles; Carfax recorded 1,206 miles. If delivery mileage were truly 131, the vehicle would show ~677 miles minimum—yet readings were 965–1,206 miles, proving the EV6 had approximately 413–660 miles at delivery. Willfulness Indicators: I verbally corrected mileage and color errors; the dealer ignored the corrections, submitted false disclosures, and provided only a thumb drive instead of paper contracts, preventing immediate verification. Carfax confirms incorrect DMV data originated from dealer submissions. Requested NHTSA Action: Investigate for violations of the Federal Odometer Act, audit the dealer’s odometer/title practices for a possible pattern, pursue civil/criminal enforcement if warranted, and refer to DOJ as appropriate.

Sun roof/moon roof exploded without reason.

When I stopped the car in a parking lot, before I could engage the parking brake, the vehicle suddenly accelerated and climbed over the curb adjacent to the side walk. Stopped for few seconds and again suddently started accelerating. I could not stop the car as the brake appeared to be disenaged completely and was going all the way to the floor. The car went on the side walk, and descended on the road from the side walk and crossed the road, climbed on the curb again and stopped on the grassy area. Side airbag on the driver side inflated and the drive seatbelt tightened.

There is a safety issue with the specific implementation of the regenerative braking system when the car is put into reverse that I have experienced on several occasions. This is not a failure or malfunction of the system as it is working as intended nor are there any warning messages or alerts to signify a defect. The way Kia's system works is that regenerative braking is always on (like all EVs), but at a level you set from 1-4, with 4 being the most aggressive. I leave it on level 4(i-pedal) because I prefer one-pedal driving which I find to be more comfortable and safer. When the car is parked, or at a complete stop, if I put the car into reverse then the regenerative braking level is forced down to level 3. This creates a novel situation where regenerative braking is holding the parked car in place, but also the car won't move until the acceleration pedal is pressed. So I need to tap the accelerator then quickly move my foot to the brake pedal to stop the car which takes a couple of seconds. This causes the car to lurch backwards quickly until my foot reaches the brake pedal because Level 3 is not aggressive enough to bring the car to a complete stop in a short distance. Once I have held down the brakde pedal I can use that to slowly reverse more safely. I haven't hit anyone or anything yet, but I have had a few close calls from cars or pedestrians suddenly appearing from outside my view range at the same time I'm doing that initial reverse lurch. If someone were slower than me or have some physical hindrance that didn't allow them to move their foot quickly then it would be more likely the car may accidentally reverse into a person or car before the driver could respond. Being that regenerative braking is still engaged while reversing it should be a simple software change to allow for level 4 to be enabled thus eliminating the initial reverse lurch issue.

The exterior rear-view mirrors on my car do not have detents to hold them in place in the deployed position. All side-view mirrors have such detents. The mirror assembly is held in place such that the mirrors remain aimed where the driver sets them. If the mirror experiences a significant force from, say a person walking into them, the detent releases and the mirror folds back against the car, avoiding damage. On my car and other affected cars, these detents are not present and the force of closing the car doors, wind from high-speed driving, or even a bumpy road can cause the mirrors to move from their intended position, causing the driver to misjudge the position of other vehicles, an obvious safety hazard. Posts on online forums dating back to 2022 report this issue, and by simply examining mirrors on a reasonable-sized sample of Kia Ev6s, it's obvious that this is a widespread issue. Online posters have reported that Kia dealers have denied the existence of the issue by claiming that "it's designed to be this way." My own dealer also made such a claim. I was unable to find a single vehicle, Kia or otherwise, other than 8 samples of EV6s that exhibited this behavior. This defect appears to only affect EV6s that do not have electrically-folding mirrors.

Vehicle ICCU blew up while driving, causing drive train system shut down and limited speed to 10 mph.

About 10 miles from home a warning saying to check the electrical system came on the dash and the car would not go faster than about 25 miles per hour. We had to limp back home, turning the car off every few miles as it would start aggressively beeping to turn off the car. After getting it towed to the dealership, it took them several weeks to determine it was the ICCU and fuse, and I did not take possession of my car back for nearly 8 weeks. While this was under warranty, I am still currently waiting for reimbursement on the tow to the dealer and the rental I had to get for 3 days before the dealer could get me a loaner.

8 days after purchase from dealer, new vehicle, it went into "zombie" mode. Electrical system for radio, climate, lights, etc. all worked but it wouldn't come out of park or neutral. The online app kept saying there were no mechanical problems even though it was "dead in the water" and couldn't be moved. Then the electronic parking brake engaged so it could not be towed. It had less than 400 miles, had been working fine in the prior 7 days. Stopped at Home Depot, when I came out it entered zombie mode, and it couldn't be moved or put into gear. Even though it was in neutral at times the electronic parking brake kept it from moving. I was told today it was a "front inverter" and Kia had to approve repairing it????

Heard a pop, followed by power failure and warning lights to stop operating the vehicle. The ICCU unit had blown.

ICCU failed. Heard a popping sound from rear of passenger compartment, dash errors lit up, car went to limp mode

Description of Incident: 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The high-voltage battery system and charging system in my 2024 Kia EV6 malfunctioned. Despite showing 40 miles of range remaining, the battery suddenly dropped to 5 miles before the car became completely unresponsive and failed to charge. Additionally, the vehicle could not be shifted into neutral or powered on. The vehicle is available for inspection upon request. 2. How was your safety or the safety of others put at risk? The sudden loss of battery range left me stranded at a Shell Recharge station in Elkridge, MD, at [XXX] on[XXX]. Being stranded at this hour posed a personal safety risk, especially in an unfamiliar area, as I was unable to move the vehicle. Moreover, the malfunction could endanger drivers if such a failure occurred while driving. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem has not yet been reproduced or confirmed, but I previously reported symptoms of 12-volt battery issues to the dealership on November 12, 2024, one day after receiving the vehicle. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle has not yet been inspected by the manufacturer or any other representatives. I am awaiting guidance on next steps from Kia and the dealership. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? Yes, I noticed warning signs related to the 12-volt battery on November 12, 2024, shortly after receiving the vehicle on November 11, 2024. However, no specific warning lamps or error messages appeared at the time of the failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine/power of my electric EV6 died. It went into limp home mode (speed limited) briefly before dying completely. I restarted it and was able to get it to a parking spot before it died again, but I was just lucky I was on a surface street with parking. Dealership confirmed it was an ICCU failure

I see there is a lot of battery issues with KIA EV6 out lately; my car randomly died near my house and nothing was working, doors wouldn't open/close, hazard light wouldn't come on.. had the car towed to the dealership same day. they claim that they fixed my car properly and fixed the recall issue with the battery.. drove the car back home the same night. next morning; car is again dead and nothing is working; I feel very unsafe driving this car and i see online hundreds of kia EV 6 is having same issues. I don't think Kia is properly addressing this issue or the technicians know how to properly fix this.

ICCU failure while driving. Vehicle defaulted into limp-home mode and required towing to a dealership once it fully died. The issue was confirmed to be the ICCU and the part was replaced.

Car suddenly slowed from 55 mph to 25 mph because of issues with the 12v battery and the ICCU system. The car is only 1 year old. From looking online, this seems to be a fairly common issue/problem. The dealer is working on it now, but it seems likely that this issue will happen again. If it happens on a freeway, certainly a safety concern.

Right front tire failed while driving on interstate highway. Sidewall blowout. The tire is available for inspection. Stability of car compromised could have caused an accident. The problem has not been reproduced. The tire was seen by a state trooper and inspected by Les Schwab tire dealer. There were no warning signs.

I have a 2024 Kia EV6 I took my car in for an unrelated repair. Tech found an airbag code that I asked to be investigated. The airbag wiring harness was damaged and needed replacement. The repair was quoted as $6600. The dealer claimed that this was from rodent damage but the photo evidence does not look like rodent damage. It looks like the wire was pulled out of the harness. Of note, the 2024 Kia Niro and 2024 Kia Telluride have similar active recalls. Please see NHTSA Recalls 25V-024 and 23V-035.

Kia has a known ICCU issue with several of their electric vehicles. Mine went out yesterday creating an extremely dangerous situation on the road. After it blew, I lost the ability to accelerate or steer. This was obviously very scary for me and the drivers around me. I feel very lucky to have not been hit by another car. Although Kia is replacing these, this does not guarantee a fix. That is to say, the ICCU has the potential to blow again after replaced because the core issue is not something that Kia group has reengineered. I should not have to fear getting into my vehicle and wonder if it will blow again. I hope the government steps in and conducts an investigation into this. It’s only a matter of time before someone, unfortunately, will lose a life over this.

I was driving on the freeway steady at 72mph and the car suddenly accelerated on its own. It hit 90 within seconds and I had to step on the break for the car to slow down.

Brakes failed with unintened acceleration. We were stopped behind a truck at a stoplight when the the vehicle accelerated with a foot on the brake. We had it towed from the scene of the accident to our local dealership for testing. They had the vehicle for 4 weeks. Kia customer care was not responsive to our calls and emails or the dealerships. The dealership could not confirm the cause without their cooperation. The police were called to the scene of the accident and there is a report. The vehicle has been looked over by the service department at our local Kia lot. It was appraised for cost of damages by the collision center.

[XXX] about [XXX] our 2024 Kia EV6 WIND RWD AUTO VIN: [XXX] already serviced in both NHTSA Campaign #: 24V867000 and Campaign #: 24V200000 had a sudden loss of drive power and nearly all control while driving in rush hour traffic at 65MPH on [XXX] between Atwater and Livingston. The confirmed failed ICCU component can be inspected at Modesto Ca Kia. The sudden loss of drive power and control in rush hour highway traffic put me and numerus other rush hour highway drivers at catastrophic risk of multiple crashes, this could happen to anyone with the same car and especially concerning because our car had ALREADY been serviced in the 2 previous NHTSA recalls (see above) for the very issue (ICCU) that impacted our car nearly resulting in a catastrophic outcome. The confirmed failed ICCU component has only been inspected, and confirmed failed by the KIA EV certified technician at the Modesto Ca Kia dealership. Since owning the car [XXX] a yellow 12 volt battery lamp indicator, not a warning light, on the front dash would occasionally be lit randomly while driving or parked. Just moments before the sudden loss of power and control numerus warning lights and messages were appearing and the displays were flashing on and off. We had absolutely no: warning lamps, messages, symptoms, nor any other issue whatsoever with our car prior to this sudden failure while driving on the highway.

While driving in the rain, the vehicle failed to decelerate and brake efficiently. There were two event this morning (12/18/24). 1. Approaching a red light with Regen braking set to lvl 3 the car failed to slow after removing my foot from the accelerator. Quickly i began applying braking force with the brake pedal, but there was no change in the vehicles speed. Finally I firmly forced the brake pedal to the floor and the car came to a quick stop with ABS kicking in. Thinking that some of the sensors may have been affected by the wet road conditions, i disabled regen/ self braking. 2. With regen set to zero I began approaching slower traffic in a bend on the highway. When i saw brake lights ahead i began to brake and the pedal did not respond. It wasn't firm, nor soft just "regular". Knowing that i had distance to avoid collision, i let off the brake then applied again. This time-still nothing. I'm running out of space now so I quickly jab the brakes, activating abs, and avoiding the rear end of the pickup in front of me. I have yet to take the car to the dealership as they don't open until 9am (currently 7:44 am). I fear that they will not be able to replicate problem unless it is still raining when i arrive.

In NORMAL driving mode, when I fully depressed the acceleration and quickly release, the vehicle continues accelerating . I almost crashed into the car in front of me in stop and go traffic.

When washing my car at an automated car wash my brakes failed when exiting the facility. When the wash was completed it gave me the approval to leave. I tapped on the gas pedal to get the car moving slowly. The car started to move down the ramp and when I applied the brakes there was no response. I pumped the brakes several times but they did not engage. I tried to hit the parking brake and shift into reverse and nothing happened. I finally had no choice but to hit a wall to keep from hitting a vehicle. I did contact the dealership and they were non responsive. They indicated they had never heard of a wet brake issue on this vehicle. I provided them with several statements from the EV6 Forum. My vehicle had less than 600 miles on the odometer.

I leased a 2024 Kia EV6 on 1/27/24. On 2/22/24, twenty-six days after leasing the vehicle and an odometer reading of 616 miles, while on Washington state highway 903 there was a pop sound, the car slowed, and stopped displaying a “Check electric vehicle system” error. Due to the pop sound, we pulled over and barely made it off to the side of the highway before losing forward momentum. If this happened on a crowded freeway, the vehicle could have been disabled in a traffic lane. After 39 days, the dealer's service department found that inverter was "burnt and charred showing evidence of a fire in the system" and that the fire "potentially damaged the rear drive unit".

There are alot of electrical malfunctions including unnecessary and without warning emergency breaking that has injured me ( I temporarily have a rental car to recover from a right thoracic sprain, left hip contusion, and a right anterior chest contusion- I have medical documentation), the steering wheel jerking when no correction needed, the vehicle locking up on the tow truck driver, and a lot of different electrical malfunctions that seem to indicate a bigger problem. I have more evidence, but it would not let me submit more pictures.
