2024 Kia EV6: sudden loss of power

Filed Sep 27, 2026 · Acceleration, Electrical · GA

Dear Kia Customer Care, I am writing to formally report a serious and recurring safety issue with my Kia vehicle. I have repeatedly experienced a "Power Limited" error while driving, often accompanied by a turtle icon and a "Check Electric Vehicle System" warning. On multiple occasions, the vehicle has suddenly lost power and stalled in the middle of the road. This is extremely dangerous and has put me and other drivers at risk. A vehicle should never lose propulsion unexpectedly, especially in active traffic conditions. I request an immediate investigation into this issue, along with a clear explanation of the cause and a permanent fix. Please treat this matter with urgency, as it directly concerns driver safety. Kindly confirm the next steps and the earliest available service appointment. Thank you,

Car was totally dead even with a 68% charge. AAA came out to jump start. The next day while driving on the highway the car started to lose power. A red warning to check the electrical system came on along with "turtle mode". I was able to pull over off the highway, grateful the two small children were not with me. Car was towed to dealer who kept it for the three days. Only after repeated calling could I reach someone who said they couldn't reproduce the problem. I'm afraid to drive the car at this point as I feel it's just unsafe to do so. This seems to be an ongoing issue that Kia can't seem to fix.

I had an ICCU failure on 4/12/26. I was fortunate enough to be close to home, so I was able to get back home before the vehicle dropped into reduced power mode. As has been reported many other places, I heard a loud pop and moments later a number or warning messages came up on the display. It was towed to the dealer the following day and has been confirmed to be an ICCU failure.

2024 Kia EV6 leased January 2025. Vehicle is subject to the federal safety agency Recall 24V‑867 / Kia campaign SC327 for the Integrated Charging Control Unit (ICCU). The recall remedy was performed at an authorized Kia dealer in July 2025 (software / operational logic update). The defect was not cured. Three months after the recall remedy was performed, the vehicle suffered complete loss of electrical power and would not move. It was towed to the Kia dealer. The dealer's own diagnostic recorded code P1A9096 — the exact diagnostic code Kia's recall instructs technicians to check for — and replaced the ICCU and high-voltage fuse. This is the recall-defined failure occurring AFTER the recall remedy was applied. Approximately three months later, the vehicle again suffered total loss of power and would not start in cold weather. It was towed in. The dealer replaced only the 12-volt battery and did not address the ICCU, despite the documented prior ICCU failure on this VIN. The 12V battery failure is a known downstream symptom of ICCU failure on this platform. Approximately one month after that, the vehicle returned for charging system failure ("vehicle charges briefly then stops") and a "check electrical/hybrid system" warning that appeared while driving. Diagnosed as charging port failure. Vehicle was out of service approximately 27 consecutive days. Total cumulative days out of service across four visits: approximately 35-40. Two safety-related stranding incidents resulted from these failures. Both occurred in winter conditions in Pennsylvania. In the first, the driver was stranded in a parking lot at night during a snowstorm in sub-zero conditions; three tow trucks were dispatched before a flatbed could recover the vehicle because the EV could not be towed conventionally with no power. In the second, the vehicle died in a school parking lot during a snowstorm; the first dispatched tow truck could not recover an EV with no power, and the driver had to walk multiple miles home in freezing

Vehicle display showed a message stating 12 volt battery was low and to pull over immediately, the car the died in a parking lot. I called KIA roadside service and they connected a battery pack to the 12 volt battery and got the car started. This could have been a serious problem if I was on travelling on a public street or highway and suddenly lost power.

After starting the car, a message displayed on dashboard "Check Electrical System." I tried driving the car out of the garage and then a message displayed to the effect of "Stop the car and check battery." I called the dealer and they said to have the car towed to them. After having the car towed to the dealer, they ended up replacing the Integrated Charging Control System (ICCU) and fuse. The danger is that the failure of this ICCU part could cause immediate loss of power when driving. Luckily, that didn't happen to me since I was only creeping slowly out of my garage.

I had just left my house and pulled onto a 5 lane road when the ICCU died. The car lost power while underway. This posed great danger as the vehicle became unable to safely navigate traffic and pull off to safety. Kia is well aware of this hardware problem, tried to fix it with software updates, and deflates the affected number of vehicles. To make matters worse, they tried to deny this was a recall because they claimed the recall was fixed via the software update. This affects every single Kia Hyundai and Genesis EV.

The driver (my wife) was operating the Kia EV6 (with approximately 10,000 miles) when the vehicle suddenly experienced a severe loss of motive power. While driving, a warning message appeared on the dashboard indicating an issue with the power supply. Immediately after, the vehicle forced itself into "turtle mode," severely restricting the maximum speed to 20 mph and refusing to accelerate further. This sudden, unexpected deceleration on an active roadway put the driver at a significant risk of a rear-end collision. The driver managed to slowly navigate the vehicle back to our residence at a maximum speed of 20 mph, which was extremely hazardous. Shortly after safely parking at the residence, the vehicle experienced a complete electrical failure. It would no longer start, could not be shifted into neutral, and ultimately had to be dragged onto a flatbed tow truck by roadside assistance because the wheels were locked. The vehicle was towed to an authorized Kia dealership, where it is currently undergoing diagnosis and inspection for what is heavily suspected to be a total failure of the Integrated Charging Control Unit (ICCU) and 12-volt battery system. The vehicle and the failed components are currently at the dealership and are available for inspection upon request. Note: This catastrophic power loss occurred just weeks after the vehicle was in the shop for nearly a month to have its entire high-voltage battery pack replaced due to severe range degradation, marking the second major electrical system failure on this vehicle.

While operating my 2024 Kia EV6, the vehicle began displaying repeated warnings related to the power system and 12-volt battery. The instrument cluster first showed a “Power limited” message, followed shortly by a “Stop vehicle and check power supply” warning. At the same time, the vehicle indicated that the 12-volt battery was low, despite the high-voltage traction battery being at or near full charge. Shortly thereafter, the 12-volt battery became fully depleted, resulting in a complete loss of low-voltage electrical power. I was unable to electronically unlock the doors, and the vehicle could not be started or shifted into gear. The vehicle became immobilized and inoperable, requiring towing. This failure occurred without warning and created a safety concern, as loss of power could potentially occur while driving or leave occupants stranded and unable to access the vehicle. The vehicle had previously been serviced at a Kia dealership for known power system concerns related to the Integrated Charging Control Unit (ICCU). During that visit, the dealership applied a firmware update only and did not replace the ICCU hardware. The current failure occurred after that firmware update, suggesting the issue was not resolved. This incident represents a loss of motive power and loss of vehicle electrical systems, which could present a serious safety risk if it occurs while the vehicle is in motion or in unsafe environments. The inability to unlock doors or start the vehicle due to complete 12-volt battery depletion is particularly concerning. When roadside assistance arrived to tow the vehicle to the dealership, the vehicle’s 12-volt battery was completely depleted, preventing normal recovery procedures. A portable jump starter was temporarily connected, but the vehicle would not remain powered on long enough to complete the steps required to place the vehicle into neutral or tow mode.

on April 7, 2025, our 2024 Kia EV6 was towed away from our driveway after an ICCU failure the day before. The tow truck driver attempted to jumpstart it with a battery eliminator and he could not. He could not get it shifted into neutral and had to pull it up on the ramp with the back tires stationary, sliding up the ramp. They had it until we got it back just before April 22, and then on that day, it was towed away again because of a 12 V battery failure. If this first computer failure had happened while we were on the highway, we would have lost power in traffic. We were told that the replacement ICCU part which we received was a different model number than the first one, but I have heard on Facebook discussion groups that it is identical and just as likely to have a failure. Our Kia EV6 is a 2024 model, an extended battery version Wind AWD. Both the initial incident on April 6 and the second incident on April 21 happened just outside my garage after just backing the car out of the garage going maybe 5 mph. For some reason, the system will not let me upload a video of the first time it was towed up the ramp, only the second time when it was taken away for the 12 V battery failure, but it also would not drive in that condition. I include parts of texts with the Kia service center. It took them one week to be convinced that it was, indeed, the ICCU.

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.

[XXX] about [XXX] our 2024 Kia EV6 WIND RWD AUTO VIN: [XXX] already serviced in both the federal safety agency 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 the federal safety agency 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.
