Source & disclaimer
Dealers make ~$8,315 on the average car loan.
After the price is set, the finance manager runs four plays to rebuild margin. Every buyer without a pre-approval is a target. Here's exactly what they run — and what stops each one.
78% of dealer loans carry a hidden +1.13% markup above what the lender actually charges. You never see it — it's buried in the contract. · CFPB
Dealer must match or beat your lender — they can't add margin invisibly. The markup play is dead on arrival.
Once you answer, they stretch the term to hit your number. Median result: $4K less off the price, 12 more months on the loan. · Industry avg
Financing is done. Only the sale price is on the table — and the dealer knows it.
Back-office F&I profit averages $1,975/vehicle, up 8.5% YoY. These products exist — but dealer markup is 4–10x what you'd pay elsewhere. · Dealership Guy
Dealer GAP runs $500–1K. Your insurer sells the same coverage for $100–250 over 5 years. Now you know.
"Your loan fell through — come re-sign." This pulls your APR up +5% on average. It's legal. It works because you've already driven the car home. · Ctr for Responsible Lending
A lender commitment letter means the deal is final. "Pending dealer approval" doesn't apply. You can't be yo-yo'd.
That's 21 months of your car payment — handed to the dealer's finance department for nothing.
Takes 2 minutes. No obligation to use it — but you'll walk in with all the leverage.
Pre-approval is a soft credit inquiry — no score impact. FICO treats all auto-loan hard pulls within 14 days as one, so you can still shop rates at the dealer.

Dash board showed limited power couldnt accelerate above 10-12 mph pulled into residental area dash then showed warning sign 12v battery then car died in middle of street. Could not put car in neutral called dealership said car cannot be put in neutral without special tools. I had taken it in for recall in 2023 or 2024 cant remember. Luckily i was not on highway as i could not even turn on hazard lights and car shut off abruptly.

ICCU failure. Was confirmed by shop car was towed to over phone. But no mention of it on invoice as of yet. I was at traffic light when I heard a pop and when I tried to go, got the warning message to pullover and the turtle icon. I made it to a towable spot. Super fortunate all in all. Can’t imagine if on highway in weather. No hints of failure before. Car was recently purchased month prior. I took it in for recall within first week, was told all good, software was updated. I kept between 20%-80% at all times, charged lvl2 at work daily and lvl1 at home sometimes. Had cheap voltage meter in car and was reading fine. Hope to get my car back soon.

I was driving on a residential street at fairly slow speeds, like 25 mph. There was a stop sign so I engaged the brakes and the car did not smoothly slow down but instead it felt like the back tires locked up and a skid started and I actually went into the intersection before coming to a stop. There was no ice, no sand, just the road surface and the skid in the rear of the vehicle.

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.

Well, at first I got the 12 V battery fixed because it wasn’t throwing the code because my 12 V battery wasn’t holding power and then I did get the code and it turned my vehicle into turtle mode where it would not move. This could’ve been very unsafe in the car. I have brought it in now and it has been 20+ days and I have not had resolution and I have not received the part to fix my car. I have been left as a single mother without another vehicle to use the dealership offered me a vehicle and I was driving that, but it has issues with the Wheel bearing and rotors which at first they told me I would be held liable for driving and then they told me to continue driving it since then now I am renting a vehicle which I cannot afford as I said I am a single mother and I can’t afford $300 a week and then we wait to be reimbursed by Kia they have done nothing to help me and my situation and I am concerned. I have had this car for less than two years. I have less than 24,000 miles on it and by Iowa lemon law it should be resolution into it getting fixed so I am making a formal complaint.

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 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.

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.

A couple of months ago the breaks started making a strange grinding noise and it starts vibrating for a few brief seconds, but violently. There are no warning lights or any indication of malfunction. I took it to the dealership and they allegedly fixed it. Nevertheless, less than a month later, the noise came back, and not just a noise, but the vehicle attempts to stop abruptly without me engaging the breaks. It happens intermittently, and it is quite scary when it happens while driving high speed on a freeway. It creates safety issues. This is not my first EV. I am very familiar with EVs, regenerative breaking, and so on. This is not a regenerative breaking issue. I don't even know how to properly describe it. it is very unusual.

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 make sure the i-Pedal mode remains stable and reliable under all driving conditions and even after vehicle is turned off and back on.

On four separate occasions while driving on the highway between July thru November 2023; vehicle has had a loss of motive power (reduced speed) increasing risk of crash. Due to loss of motive power unable to accelerate to get out of way for merging traffic, also when approaching hills on interstate car would slow to speeds of less than 40 mph; unable to accelerate or move out of the way when fast approaching vehicles from the rear. I had taken the vehicle to a dealership on three occasions to seek resolution to only be told all diagnostic testing did not reveal any issues. Dealership has performed updates to the systems as well as recall update for ICCU upgrade, nothing to date has resolved this issue. I’m fearful to drive vehicle on highway that someone will slam into my car potentially causing harm or death.

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.

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.

ICCU failed despite all prior recall updates being performed. Incident began when home circuit breaker tripped; vehicle subsequently refused Level 1 charging with "Check Electrical System" warning. Per dealer suggestion, tested public chargers. Level 3 (DC) worked, but upon connecting to Level 2 (AC/J1772), a loud "pop" occurred, and the public charging station immediately suffered a mechanical failure/shutdown. Vehicle then displayed "Stop vehicle and check power supply," and was unable to drive above 40mph (with a turtle icon visible on the dash) once I pulled away from the charging station. This created a significant safety hazard while navigating traffic. Within two hours, the 12V battery was completely depleted; vehicle was unresponsive and required a jump-start for towing. Dealer confirmed ICCU failure requiring replacement. The fact that the vehicle's internal failure caused the immediate malfunction of public infrastructure is deeply concerning, as was the loss of motive power on the road.

Level 3 (DC) worked, but upon connecting to Level 2 (AC/J1772), a loud "pop" occurred, and the public charging station immediately suffered a mechanical failure/shutdown. Vehicle then displayed "Stop vehicle and check power supply," and was unable to drive above 40mph (with a turtle icon visible on the dash) once I pulled away from the charging station. This created a significant safety hazard while navigating traffic. Within two hours, the 12V battery was completely depleted; vehicle was unresponsive and required a jump-start for towing. Dealer confirmed ICCU failure requiring replacement. The fact that the vehicle's internal failure caused the immediate malfunction of public infrastructure is deeply concerning, as was the loss of motive power on the road.
My vehicle has been in the possession of Koons Kia of Owings Mills since March 15, 2026, for diagnosis and repair of this issue, with service beginning March 16, 2026. During this time, the dealership has replaced the 12-volt battery and performed a software update; however, the defect has not been corrected. On April 10, 2026, I was notified that the vehicle was ready for pickup. When I arrived on April 11, I found that the battery was completely discharged and the issue had not been resolved. Because the vehicle was not operational at the time of attempted pickup, it was not returned to me and remained in the dealership’s possession. I was contacted again on April 13, 2026, and informed that the vehicle had been repaired. When I returned to the dealership on April 14 to retrieve the vehicle, I again found that the battery was discharged and the defect persisted. As a result, the vehicle was not returned to me and has remained continuously in the dealership’s possession since March 15, 2026. As of today, the vehicle has been out of service for more than 30 consecutive days due to this defect, and multiple repair efforts have failed to resolve the issue. This ongoing condition substantially impairs the use, value, and reliability of the vehicle.

Got in my car to leave a store and heard a loud pop and noticed a smell like an electric motor burning. Backed out of my space to drive home and the car displayed several error messages- Check electric vehicle system, turtle mode, power reduced. I was stranded and had to order a tow truck to be towed to the dealer and get a ride home.

Repeated failed attempts to repair ICCU culminating in ICCU failure. May 15, 2024 – Initial repair attempt (ICCU-related recall/service). September 5, 2024 – VCMS logic recall performed. December 19, 2024 –second repair attempt for ICCU-related issue. October 16, 2025 – Limp-home logic recall performed. March 11, 2026- Vehicle experienced a complete loss of power and was rendered undrivable. Repeated attempts to avoid ICCU failure still resulted in said ICCU failure and a loss of propulsion event while vehicle was on the road.

I was driving 40mph and received a yellow error message along the lines of "electrical system issue, please check" and my speed was limited to 25mph. After trying to get the car to a safe location (as I was on a narrow two-lane road), the error changed to a blinking red error and my speed was further limited to 12mph. I was unable to get the car one mile to the dealer for service, so I stopped the car in a parking lot and had it towed to the dealer. The dealer diagnosed the problem and replaced the ICCU (2nd time on this car) and the 12 volt battery.

My (EV6) failed to charge on both Level 1 and Level 2 charging. A “Check Electrical Vehicle System” message appeared on my dashboard. I took my vehicle to my nearest dealership, where the technician confirmed a faulty ICCU. Fortunately, my vehicle was drivable, and this failure occurred at home rather than on the highway, which could have been a significantly more serious issue. A part has been ordered, and the vehicle has been in the shop going on two weeks.

In November 2025, after charging car overnight, backed out of driveway and began to drive. Within 100 feet, received red error message and tone: “Stop vehicle and check power supply”. Stopped the vehicle and got it towed to Kia dealer, who confirmed that the ICCU had failed, despite the car having received the software patch purporting to fix the problem. The ICCU was replaced under warranty within a week. We were fortunate that this occured very close to home, without safety consequences. Ten minutes later, the car would have been travelling at 65 on a highway with no shoulder for long stretches, which would have been very dangerous. This was a certified preowned EV6 with less than 9000 miles on it. The 12 volt battery was brand new, having been replaced 3 months earlier with an AGM battery as a possible preventative measure for this issue.

The ICCU fuse blew. As I was driving, the car began to lose power. Fortunately I was able to pull into a parking lot before I lost all power. It's the same issue as the recall SC327Y1 from NHTSA, which occurred although the software update had already been performed previously. The dealer is replacing the ICCU and ICCU fuse under SC327Y1 after inspecting it. I did receive a warning as I was driving that the car was low on power.

The ICCU failed. The vehicle suddenly stopped on the road, would not go into any gear and could not be moved whatsoever, was stuck on the side of the road in a dangerous position. Called roadside assistance, after a few hours the vehicle was towed to the nearest dealership. After a week the vehicle had the ICCU replaced under warranty.

The component that is seeming to fail in most KIA EV6's is the ICCU assembly. This is the component that failed in my KIA EV6 GT. Part# 364-1XFA0AQQK Also the ICCU Fuse, Part#375F2-GI040QQK FUSE-HIGH VOLTAGE. My safety and everyone around me was put at risk when the vehicle loss power due to this ICCU failure. As I entered the highway the vehicle starts loosing power. The vehicle gradually lost power more and more over time. I was able to make it to an exit driving at approximately 20-30 mph, and was able to drive it back to my house where it was then towed to a dealership. The problem has been confirmed by the dealer. I have the invoice to prove the repair of the ICCU. Yes there were warning messages on the screen when the ICCU failed. First, there was an audible "POP" which was the fuse blowing first. Once the fuse blows, it slowly kills the 12v battery and the car then looses power and you're no longer able to drive the vehicle. At that point, the ICCU is blown. The error message showing on the screen was: "CHECK ELECTRIC VEHICLE SYSTEM". Then the display starts blinking red and displays "STOP VEHICLE AND CHECK POWER SUPPLY". I have all the screenshots of the error messages the vehicle displays. The text message that is attached to this complaint is the service tech informing me that the 12v battery that they charged me $366.66 for, DID NOT FIX THE ISSUE. Yet they still charged me for the battery. This dealerships service department had my car from January 21, 2026 to March 4, 2026. A total of 42 days. At the time of the text message, it had already been past one month. I would like to be reimbursed for this cost.

On April 24, 2025, I plugged my Kia EV6 into my 48-amp hardwired ChargePoint HomeFlex at 7:26 PM. Around 10:30 PM I heard a noise outside but did not investigate. At 12:25 AM I noticed I had not received a “charging complete” notification. The Kia Connect app showed the vehicle at 74% and no longer charging. The ChargePoint app was unresponsive.\n\nThe next morning I found the charger’s 60-amp breaker had tripped. After resetting the breaker and rebooting the charger, the EV6 would not start charging and displayed no “Charging started” or “Charging unsuccessful” message.\n\nI then attempted to charge using a portable Tesla Level 1 charger on a 120V GFCI outlet. The EV6 briefly announced “Charging started,” but the dash showed no charging data. The outlet’s GFCI breaker tripped. After resetting, the breaker immediately tripped again when reconnecting the vehicle.\n\nI attempted to drive to a nearby DC fast charger. Upon shifting into drive, the vehicle displayed “Check electric vehicle system” and entered power-limited mode (would not exceed 20 MPH). I returned home. While backing into my driveway, the vehicle triggered a red alert with “Stop vehicle and check power supply.”\n\nThe vehicle was towed to a Kia dealership. They diagnosed a failed ICCU (Integrated Charging Control Unit) and high-voltage fuse. The ICCU recall issue is known for this model. Repairs took over two weeks due to parts delays. The ICCU and high-voltage fuse were replaced.\n\nThe ICCU failure also damaged my home ChargePoint charger, which required replacement under warranty

1st instance: Battery Coolant errors that occurred on and off. 2nd instance: The ICCU unit failed and car was not able to charge via level 2 and only fast charge. Car was still operable. Dealer replaced ICCU 3rd instance: The ICCU failed and car was rendered inoperable. Dealer Replaced ICCU. We are now on our third ICCU since we purchased the car in 11/26/2022. This would be considered a lemon law

While charging my vehicle at a level 2 charging station, my vehicle ceased charging. I received no other warnings or symptoms prior to my vehicle ceasing to charge. Upon being alerted by the Kia Access app that the charging stopped, I went to check my vehicle and none of my doors would unlock in response to the buttons on my keys. I had to manually unlock my driver side door in order to enter my vehicle. I attempted to start my vehicle and unplug/re-plug in the charger, but my vehicle would not start or charge. Using a portable jump starter, I was able to jump start my vehicle and begin charging again. However, after approximately 5 minutes of charging, my vehicle stopped charging and once again would not start. At that point, I called for my vehicle to be towed to a Kia Service Center. The Kia Service Center was able to reproduce the problem of my vehicle not starting or charging and informed me that there was an internal short circuit caused by a bad Integrated Charging Control Unit (ICCU). The bad ICCU shorted my ICCU fuse, resulting in the draining of my 12-volt battery. The ICCU and fuse were replaced at no cost to me. Although my vehicle is available for inspection upon request, the parts that malfunctioned have been replaced with new, functioning parts. My safety or the safety of others were not at risk in this situation, but I was fortunate that my 12-volt battery died while parked and charging, not while I was driving, which could have caused an accident.

While the vehicle was on the charger, the ICCU failed which then caused then fried my JuiceBox EV40 charger and flipped the dedicated circuit breaker. The car has since been repaired. I am concerned that this is a dangerous failure. If it happened on the road it potentially left me without propulsion. I'm also concerned that but for the circuit breaker functioning as designed it could have caused an electrical fire. My understanding is that this has been an ongoing problem with Kia and Hyundai EVs. I do not believe that Kia/Hyundai are taking responsibility for fixing the problem that have not plagued other manufacturers.

While driving the car we heard a loud pop in the cabin. That was followed by electrical warning lights on the dash. WE were only about a mile from home and did make it back safely at greatly reduced speed. The ICCU was confirmed to have failed by the dealership. The part was replaced. If we had been traveling on the highway it might have been difficult to find a safe place to exit the roadway.

Pulling out of garage, car warned of limited speed and then within about 30 seconds completely shut down-- could not move, operate locks, etc. Car could not be started again and had to be towed away. 12v battery had been drained down to 4v due to failure of ICCU unit. Dealership replaced entire ICCU unit and fuse.

While driving in the evening with an estimated 180 miles range remaining a "pop" noise was heard. About a minute later a vague warning message the car had not displayed before appeared. We tried to make it home but concerning (and still vague) messages kept appearing quite rapidly. The car slowed down and came to a halt and died in an intersection. This all happened within five minutes of hearing the "pop" noise. Once the vehicle died the head and taillights went off and the car would not allow the emergency flasher lights to be turned on. It would not allow it to be put into neutral to allow it to be moved out of the intersection. It also would not allow any of its doors to be locked (manually or otherwise) except for the driver's door until the vehicle was repaired one week later. We found out following that the 12 volt battery had not charged due to a DC/DC converter input voltage sensor fault related to ICCU failure. The popping noise had been a fuse. As the applicable ICCU parts were replaced by the dealership I doubt they will be available for inspection. The safety of my family was put at risk by: - the car's warnings not clearly explaining what the issue was. - the car not giving clear indication of how quickly it would die. - the car dying in a busy intersection. - the car being unable to be shifted to neutral. - the car's warning flashers not being operational when it died in the middle of the intersection at night. - us being left without warmth in outside temperatures around 6 degrees Fahrenheit. The ICCU problem was confirmed by the dealership we purchased the vehicle from. The vehicle was only inspected by the dealership acting on behalf of Kia.

The ICCU has failed twice in my EV6. It is a fairly common issue for this vehicle. I had the ICCU replaced after the first failure, but it has failed again. There was no indication something was wrong with the car until I heard a pop and then the dash indicated "Check Electrical System"

10:00 am January 28th AFTER A DRIVE OF APPROXIMATELY 20 MILES TO THE GROCERY STORE, we parked the 2023 Kia EV6 Wind,in the parking area, then entered the store to shop. On returning, we placed the groceries in the trunk and proceeded to leave for home. The push button "START" provoked a notice on the dash that the 12 volt battery was "LOW". The drive circuits would not enable. Prior to going in the store the dash information reported the main battery was at 62%, all else is normal. We are now stuck 20 miles from home. We called KIA roadside assistance, via a cell phone. The Kia site told us it did not recognize the VIN number we had entered three separate times.. It would not proceed down the logic tree for us to be assisted by their service. We called:AAA"they sent a service truck with a jumper battery which allow us to get a small charge on the 12 volt system, enough to get us home. Immediately upon arriving I opened the hood, retrieved my "Fluke DVM" to measure battery voltage. 6.2 volts was the reading. The 12 volt battery was not charged by the voltage regulation system in our car. Fortunately, we were dressed well, being the temperature outdoors was 14*F at the time and we had access to the grocery store for safety. Yet still a major inconvenience due to breakdown. Later, I disconnected the negative battery terminal, then connected the 12 volt AGM battery charger I have purchased for home use. The battery was charged to full overnight to 13.2 volts. I removed the charger cables, then left the battery set for 12 hours disconnected from the vehicle. The voltage dropped to 12.6 volts dc, indicating a healthy battery. This morning January 29th, I called the Kia dealership to explain our problem, the scheduler has acknowledged a possible bad charge control unit, but told me if it was not a control unit problem, I would pay a fee of $135 dollars for the troubleshooting, even though the vehicle has approximately 33,000 miles.

10:00 am January 28th AFTER A DRIVE OF APPROXIMATELY 20 MILES TO THE GROCERY STORE, we parked the 2023 Kia EV6 Wind,in the parking area, then entered the store to shop. On returning, we placed the groceries in the trunk and proceeded to leave for home. The push button "START" provoked a notice on the dash that the 12 volt battery was "LOW". The drive circuits would not enable. Prior to going in the store the dash information reported the main battery was at 62%, all else is normal. We are now stuck 20 miles from home. We called KIA roadside assistance, via a cell phone. The Kia site told us it did not recognize the VIN number we had entered three separate times.. It would not proceed down the logic tree for us to be assisted by their service. We called:AAA"they sent a service truck with a jumper battery which allow us to get a small charge on the 12 volt system, enough to get us home. Immediately upon arriving I opened the hood, retrieved my "Fluke DVM" to measure battery voltage. 6.2 volts was the reading. The 12 volt battery was not charged by the voltage regulation system in our car. Fortunately, we were dressed well, being the temperature outdoors was 14*F at the time and we had access to the grocery store for safety. Yet still a major inconvenience due to breakdown.

While changing lanes on a freeway, the car passed through a narrow strip of slush from recent snowfall. The car immediately disabled the motors, preventing acceleration and regenerative braking for nearly 50 seconds. There were no warning lights, sounds, or messages displayed on the car's gauge cluster display, either for the initial loss of propulsion or for the restoration of propulsion. This caused a loss of traction when the car eventually passed through a patch of packed snow and ice.

While driving my Kia EV6 in the middle of a snowstorm, the vehicle experienced a sudden and severe power failure. I heard a loud popping sound from the rear of the cabin, after which the vehicle immediately entered reduced-power (limp) mode. Within approximately one minute, the vehicle shut down entirely and lost all propulsion and mobility. I was able to move the vehicle to a safe location only because I was not in traffic or on the highway at the time of the failure. Had this occurred at highway speeds or in active traffic, it would likely have resulted in a dangerous situation with a high risk of collision, especially given the severe winter weather, low visibility, and slippery road conditions. The vehicle has approximately 21,000 miles. This is the second failure of the Integrated Charging Control Unit (ICCU) in this vehicle. The vehicle was inspected by an authorized Kia dealer, who has officially diagnosed the failure as a failed ICCU and associated fuse. There were no warning lights or messages prior to the failure. The first indication of a problem was the popping sound, immediately followed by limp mode and then a complete shutdown without further warning. The vehicle is available for inspection upon request. The repeat nature of this failure, lack of advance warning, and sudden loss of propulsion represent a serious safety defect.

It seems as if the ICCU on my car failed. It will not charge and went into limp mode in order for me to drive it home a few blocks.

The vehicle ICCU failed on 18 January 2026. It previously had the ICCU inspected and updated as part of #24V-867. Warnings on screen told me to stop driving and pull over. Had vehicle towed to Dealer where they confirmed ICCU failure and initially were going to charge nearly $4000 to repair. KIA Customer care spoke to dealership and ICCU repair is now being covered. It seems apparent that the earlier fix did not resolve the issue, and raises concerns over whether KIA truly understands the underlying cause. Will the replacement fail after 30k miles? Will I be stranded?

Vehicle was normal and during the drive a warning light for "Check Electric Vehicle System" was shown, then a second warning light "Stop Vehicle and Check Power Supply" was shown, within 2 minutes the vehicle went into "turtle" or reduced speed mode and then finally the vehicle shut down completely. I was on city streets at the time and was able to park safely, but if this had happened on and interstate highway it would have been dangerous. This is a known issue with this vehicle as it ended up being an ICCU Assembly failure. There is also a safety recall for this, but Kia is not replacing the part and just doing a software update that is not fixing the root cause of the problem.

What Owners Are Saying
"Likes and dislikes of my new 2023 Kia EV6 GT line I bought this 7 months ago because I needed an electric vehicle for a new job that requires a lot of driving. I have no regrets. Here is a list of my likes and dislikes. Likes 1. Plush and comfortable driving experience. Lots of interior room. A very sporty and sleek looking car. 2. Phone charger on console that works with Apple and Android phones 3. 110 standard outlet in the back seat that I use all the time to plug in my laptop 4. Cooled front seats 5. A very decorative interior colored lights scheme that I can customized to whatever color I want it to be and the holographic display ghost image of speed and other settings on the driver's side is fine, I can take it or leave it. 6. Navigation system always finds the fastest route in rush hour traffic 7. Insane acceleration, plus just tap drive mode button on the steering wheel and instantly changes from normal to sport mode 8. Sunroof opens up with the option of either glass or opened to the air on a nice day 9. No oil changes, no repairs, no waiting in gas lines. Just plug it into my home charger and In a short time it's ready to roll 10. I had them add a trailer hitch so I can carry my bicycle rack 11. With the combination of lane assist and cruise control, rush hour traffic becomes an almost transcendent experience 12. Consumer reports gives it the highest overall rating of any EV for reliability and quality and drivability 13. The San Jose Capital Kia dealership service center is very easy to schedule my routine follow-ups with, although I don't think they really do anything except reset the next servicing reminder and maybe update software 14. 310 mi range on a full charge, or slightly less for me because I have a loaded trunk Dislikes 1. The music from my iPod only plays via Bluetooth signal. My old gas car would connect via cable and I could search for songs and it would show the music art photo of the album. This one does neither of those and the music also cuts out frequently which is really annoying. 2. The GPS works great until I'm nearing the destination and it doesn't tell me whether it's on the left or right which is a problem when I have two or more lanes of traffic that I have to cross over to get to my destination. 3. There is no "dog mode" like in the Tesla and the remote climate control setting only lasts for about 10 minutes 4. As far as I know it doesn't come with any kind of music streaming service like Spotify, just Sirius XM which really sucks 5. My bicycle rack triggers the backup alarm when backing up, and then it suddenly locks the emergency brake, very annoying."
"For anyone who actually has a subscription to Consumer Reports, this is about a close to a full-throated advocacy than you can see. Where they lack context, there is nothing wrong in any of these observations. The EV6 remains a top-tier EV option for almost every driver."
"Real Winter Range 2022 Kia EV6. Snapshot of real winter range in the Midwest with snow tires and snow-mode on. Frankly still the best for in city driving and short commutes upto 50 miles one way without a problem."
"just in case the worse happens to you and a scooter in your garage falls into your Ev6 and causes a tiny crease in the quarter panel and you cant live with it…..there is hope! Initially i thought there was no way into the quarter panel which would potentially mean having to drill a small hole... 4930Dave9 replied Jun 11, 2025 Kia EV6 Forum NottaTesla Jun 2, 2025 Looking for trailer hitch recommendation. Took delivery of my 2025 EV6 Wind last week. So far, just one issue. The trunk mount bike rack I had for my old Model 3 doesn’t fit too well on the new EV6. I’ve checked all of the bike rack brands I can think of and none of them have a trunk mount for the 2025 EV6. Anybody out there got a..."
"Consumer Reports drops its recommendation for Kia EV6 (2025) The new reports cites Predicted Reliability with the charging/electrical systems. >The EV6 is Kia’s first EV-only design. In our highway range test of our dual-motor EV6, we were able to travel 277 miles on a full charge. The Kia is taut and agile, and the ride is steady and comfortable. It glides silently down the road and accelerates briskly. Visibility to the sides and rear is restricted, and the car is saddled with annoying split-use climate and audio controls. >EV6 owners reported problems with the EV charging system, electrical accessories, paint/trim, climate system, and body hardware. >When asked for comment, a Kia spokesperson said, “Kia America is proud of our well-earned reputation for producing high-quality vehicles. >“While disappointed to learn of the loss of Consumer Reports’ recommendation of the EV6, Kia is committed to building reliable vehicles and has taken action to address the reported issues: >• Kia America issued Safety Recall Campaigns to inspect, and if necessary, replace the Integrated Charging Control Unit (ICCU) in affected 2022-2024 EV6/EV6 GT vehicles. • Safety Recall Campaigns related to the ICCU will be repaired at no cost to our customers. • Kia America supports our customers through our industry-leading 10-year/100,000-mile powertrain limited warranty. >“Kia customers are encouraged to contact Kia Consumer Affairs at 800-333-4542 with any questions or concerns related to these or any other Kia vehicle matters.” Photos & Video: 2025 Kia EV6 Photos & Video - Consumer Reports"
"I have to agree with your frustration. These vehicle companies that want to be software providers to make money of subscriptions but they develop stuff in isolation instead of asking the users (us) what would provide value or what we want. Especially when you buy an electric vehicle you identify as an early adopter and I am sure some of us would be willing to help and support in creating something any customer would be glad to use and ultimately would work. But as was said here several times, these car companies are just terrible with creating software, apps and backends that just don't do what they are designed for as they are not properly tested or calibrated to their purpose. 🤬 now that I got this rant off my chest, I spoke with Kias hotline just this morning. I have issues with the OTA updates here in Canada. They confirmed to me that their "October" update was not only pushed to November, they told me actually the update would only be released in December 2025. They must have really screwed up the dev work... #3· Nov 8, 2025 Mine shows EA stations, but as I stated in another thread, EVGO chargers at the same location are listed individually in the list. So a 6 charger location shows up 6 time"
"My Kia EV6 (2021-2024) was stolen via “GameBoy” gadget — what can owners do? Hi everyone, I’m posting here because my EV6 (year 2022) was stolen recently, and the circumstances look like the more to GAMEBOY theft method that’s being reported widely for Kia/Hyundai group EVs. I’ve already contacted Kia Europe, my local dealer, and a well-known EV YouTuber, but I haven’t seen a meaningful response yet from Kia about any broad recall/patch or clear guidance. I wanted to raise awareness and see if any owners here know more about what Kia is doing (or plans to do) — and what we, as a community, are doing to protect ourselves. **Questions I’d like fellow owners to help answer:** 1. Has anyone here (EV6 owner) knows if Kia plans some *software or hardware security update/recall/notice* specifically for this vulnerability? 2. Do you know if the newer model(s) (EV3, EV4 or EV6 refresh) have improved security / different keyless entry protocol / better immobiliser / or have Kia explicitly said so? 3. What additional protection measures are you using and how effective do you feel they are? 4. Have you raised this with the dealer or Kia and did they respond with anything concrete?"
"BTW this is what the broken charger availability status looks like on my infotainment screen; notice all show 0/#: Clicking on any one of the locations shows "Unknown" status for the entire total number of chargers present at the location: Side note--the above location is all 350 kW chargers; guess they don't want no stinkin' Nissan Leafs patronizing that particular location--haha j/k! - Arial - Book Antiqua - Courier New - Georgia - Tahoma - Times New Roman - Trebuchet MS - Verdana Post Reply Kia EV9 Forum Delicious\_Travel1989 Aug 10, 2024 OTA Update Task could not be performed"
