2024 KIA EV9 Electrical System Problems

My vehicle popped up a red vehicle warning to check the electric vehicle system. It would no longer charge, was taken to the dealership where the emergency notification was sent :suspected condition with your EV9's Battery Management System has been detected and charging has been limited. A full system check is recommended. Please schedule an appointment with your local Kia dealership as soon as possible. And another CRITICAL EV WARNING your EV battery has a critical issue contact roadside assistance. This is a 2024 and has a total battery failure.

I would also like to highlight the serious safety concern due to cell deviation (imbalance) along with SOC (State of Charge) mismatch as per my car's BMS (Battery management system) which is present in my vehicle and shared with Kia corporate. In an electric vehicle, the high-voltage battery cells, the Battery Management System, and the battery coolant system function as a single integrated safety-critical system. When battery cells are imbalanced and there is a significant mismatch between the state of charge displayed to the driver and the lower usable energy calculated by the Battery Management System, the weakest cell can reach its safe operating limit under normal driving load even though the dashboard indicates sufficient charge. If this condition is combined with a battery coolant system fault, such as low coolant level or air in the cooling circuit, battery temperatures can rise unevenly and further reduce safe operating margins.

The dashboard and control panel of my vehicle have repeatedly blacked out since shortly after purchase. These blackouts cause the entire instrument cluster and control systems, including critical safety features, to become non-functional or obstructed intermittently while driving. This creates a dangerous situation where I lose access to important information such as speed, warning indicators, and climate controls, severely compromising my ability to operate the vehicle safely. The issue has occurred multiple times, including once while driving on a highway, which put me and other drivers at significant risk. The problem has been reported to authorized dealerships, where the vehicle was inspected and software updates were attempted, but the issue persists. Despite multiple repair attempts, the blackouts continue to happen unpredictably. There have been no specific warning lamps or messages prior to the blackouts; the system simply fails without notice. The malfunction affects the vehicle’s safety system by obstructing the...

The DC charger plug won’t release after charge was completed. Waiting 3.5 for the tech to forcefully unplug and broke the charger pins. This is a known issue with Kia vehicles and costly repairs.

Battery Management System - Critical EV Battery Warning This vehicle has been back to the dealership for repairs multiple times. Including needing to swap battery cells and wires around.

The vehicle was being driven on a highway when it became unresponsive to input from the accelerator pedal and the car's dashboard indicated an electrical system failure. There were no indications of problems with the car before the electrical system failure warning appeared. The car coasted to a stop on the side of the highway, where it was disabled (i.e., it would not shift into drive or reverse). The car was towed to a Kia dealership, where it has been for more than five weeks. The dealership replaced the ICCU but that did not resolve the problem and the car remains non-functional. The Kia dealership is waiting for the delivery of additional backordered electrical system parts to see if they resolve the problems.

Received the following warning on 8/16 with 6987 miles on the car: Critical EV Battery Warning Your EV Battery has a critical issue. Contact Roadside Assistance as soon as possible. Car has been in the dealership for a week with "no estimated repair timeline" due to the battery cells failing. Car will not fully charge and is at risk of suddenly losing power and stopping, per the dealer.

While driving, the vehicle suddenly lost power and could not accelerate normally. The speed dropped and got stuck around 12–25 mph even when pressing the accelerator. This happened multiple times, usually during hot daytime conditions. It created a serious safety risk, and one time another car almost hit me from behind because my vehicle slowed down so suddenly. The dealer has inspected the car several times but said they could not reproduce the problem. Warning messages such as “Power Limited” appeared on the dashboard when the failure occurred. I also recorded multiple videos of the problem when it happened.

The instrument display panel goes black and you can’t see speedometer or hear turn signals etc.

I was driving and the car suddenly gave a number of error messages, and I could not drive above 40 miles an hour on the freeway. This was very unsafe. I had it towed to the dealership and they replaced the ICCU Unit, which appears to be a very common problem with Hyundai/Kia electric vehicles. The ICCU unit does not power the car. It should not have affected the car's performance.

The car battery cells are defective and would not charge above 60%. After faulting on electrical vehicle alarm instrument panel sometimes may show false battery state of charge.

I was driving around 60-65 mph on the highway when suddenly a warning alarm went off and the warning light read “stop vehicle and check brake system”. I took my foot off the accelerator and car continued to maintain speed. The power brakes did not work. I put the car into neutral hoping that would slow it down, but it continued to maintain speed. I went into the right lane and put on my hazards. When I had the opportunity to pull into the breakdown lane, I did so and was able to push the brake pedal manually and get the car to stop, and turn it off. When I turned the car back on again, I got the same warnings and alarms. After 5-10 minutes, when I turned the car on, everything seemed to have cleared. I still had the car towed to KIA to investigate the issue.

The contact owns a 2024 Kia EV9. The contact stated while driving 55 MPH, the instrument panel went blank. The vehicle was restarted, and the instrument panel returned to normal functionality. The contact stated while charging the vehicle at the residence, the notification “Connected” was displayed and then the “Disconnected” notification was displayed on the Kia App on the contact’s cellphone. While the contact was driving the vehicle, the same notifications were displayed on the instrument panel. The contact stated that the message "There may be problem with the Battery Management System - If the following occurs; Please contact your nearest service center or designated maintenance center". The contact also received notifications through the Kia App for NHTSA Campaign Number: 24V757000 (Electrical System) and 24V962000 (Seats) recalls. The contact had taken the vehicle to a dealer and was informed that the vehicle needed to stay overnight to be diagnosed and...

Battery keeps dying despite full charge and multiple jumps. Battery has already been replaced and continues to die even after jumping and leaving on. Car just dies despite it running after a jump.

1. Repair History and Days Out of Service The vehicle has been at CMA Colonial Kia dealership since [insert drop-off date], totaling 49 days (and counting) out of service as of 05/13/2025. The sole but critical issue is a failed high-voltage battery, which the dealership and Kia confirmed must be fully replaced. This is the first repair attempt, but the car has remained unusable for over a month. 2. Substantial Impairment to Use, Value, and Safety The failure of the high-voltage battery in an electric vehicle renders it completely inoperable, with no capability to drive, charge, or function. This significantly impairs the use, safety, and value of the vehicle: Use: The car cannot be driven at all. Safety: Battery failure in an EV represents a major system defect with fire and high-voltage risks. Value: A brand-new EV with major battery failure has diminished resale value and buyer confidence. 3. Eligibility...

My car started to not charge for more than 10mn at a time. It also showed an error message about the electrical system. I have dropped off my car at the dealership on march 3rd. No information since

Vehicles battery has somehow malfunctioned and will charge to 100% but only has ~40 miles of range. This lead to my family being almost stranded in the middle of the night without range to get home with the un expected decrease. Vehicle is currently still at the dealership and has been there for over a month. They believe they have identified a problem with the battery pack but have to send out a specialist to look at it and have been waiting for that person for over three weeks and there is still no one assigned

The windshield wipers could not complete full return to starting position due to wet snow. This caused a shuddering noise as the mechanism driving the wipers continued to try to complete its motion. Then an electrical burning smell emanated through the car.

We heard a grinding sound from rear of vehicle while driving into a park lot. Checked road and vehicle to see if there was any damage or objects hit, there were not. Shortly after driving a few miles a BMS warning was showing and we called Kia roadside assistance. They insisted on towing the car but we waited until next day so we could secure a rental. The short drive to the rental agency now gave us 4 more errors regarding “check 4WD/AWD” and the code was given as “MCU_R” to check the rear motor control units. All were listed as “P1Axxxx” errors. During this time, electronics in the car did not work well, vehicle did not want to shift into gears and acceleration was noticeably degraded. Car is at dealership being worked on now.

All of a sudden the EV battery management system warning light is on and it suggest I do not drive it until fixed. This was after my entire screen went out, where I could not see the speed I was going or use turn signals. Very unsafe

Battery cell in electric vehicle failed after 6 months of ownership.

Car would not charge on a fast charger and died on us while on a trip. We got the car towed to a dealership and two days later was told the car was fixed and ready to go. On the way home, we stopped to charge the car and the car still wouldn’t connect to charger. The car would connect to our home charger though. I took to the car to the dealership in our town where they had trouble getting it to connect to their fast charger along with the car not communicating to back of car. The car also completely died even with a full battery and had to get it towed to dealership

Battery Management System light came on 1/22 , battery wouldn’t charge past 80% - took into Kia Burlington NJ for service- they diagnosed vehicle and put it on charger and was told issue was resolved. I am noticing that my battery pack is having issues- battery pack is 99kw when it goes down to 10 % in can charge it all the way to 100% but only 50kw is dispensed. Meaning that there is 40kw of battery that is unaccounted for. My max range is extremely limited to 120mi on a full charge. I understand winter can affect range but with the constant charging- i haven’t been able to dispense the full 90ish kw of charge. Concerned about my safety and a potentially defective battery pack.

The blank screen software recall has not fixed the screen that goes blank. It is still happening. This was after a dealership visit to address the recalls.

The 12-volt battery for the vehicle was depleted, so the vehicle had to be jump-started to run. I work for a repair facility (it was here for collision repairs, as far as I know unrelated to this issue) and since I was unfamiliar with the vehicle, I inadvertently turned it off before shifting into park. When I took my foot off the brake, the vehicle began to roll forward. I am not sure if the vehicle was in park, neutral, or even reverse (the gear I was in when I turned the vehicle off), but whatever gear it was, the vehicle kept rolling after it was turned off. I tried turning the vehicle back on to shift to park, but was unable to do so due to the depleted 12-volt battery. I tried hitting the park button anyway, and this did nothing. I then tried to engage the electronic parking...

Main gauge cluster display blank. No speed info, charge info, etc. no blindspot warning or turn signal sound or anything

I am told my car did have the software update for the instrument display but I still experienced issue where I turn on the car and the display in the middle is completely black except it shows D for the gear I am in. Can’t see the speed can’t see if the blinkers are on!

Car would not shift out of park into drive reverse or neutral had to be towed to dealership

Entire dashboard went blank and was not visible

My EV9 lunged forward very abruptly when I was parking. I had to slam on the brakes before my vehicle crashed into the building in front of me. My vehicle also lost the signal (blank screen while driving ) the same day my car lunged forward. I could not tell how fast or slow I was going. I pulled over and restarted the vehicle or and my screen came back on. I began driving for maybe 4 minutes and the screen went completely black except for the “lost signal” alert in red. My vehicle has also lost the ability to use adaptive cruise control while driving my vehicle. I pulled over and when I restarted the vehicle i was able to use it again.

Our KIA EV9, which HAS HAD the software update installed to address NHTSA Recall Number 24V757 (Kia safety recall SC326) has again had the driver's instrument panel screen come up blank when the car was started. This is identical to behavior we observed multiple times before taking the car to the dealership for the software update. To resolve the issue, the car was turned off and permitted to sit for an hour before we attempted to start it again and the problem was no longer present.

The contact owns a 2024 Kia EV9. The contact stated while attempting to start the vehicle, the contact became aware that the instrument panel was dark. The vehicle was towed to the dealer where it was diagnosed that the instrument panel had failed, and a system update was needed. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact related the failure to NHTSA Campaign Number: 24V757000 (ELECTRICAL SYSTEM). The approximate failure mileage was 4,612.

On November 5th, 2024 I exited a store and my vehicle instrument panel was black when I turned my vehicle on. I turned my vehicle off and on several times trying to get the panel to work. I could also not control the headlights or turn signal with the manual controls either. It was still daylight hours and I was 2 miles from home so I decided to try and see if the vehicle could be driven home. I was able to get the vehicle home but could not get the instrument panel to turn on despite many more times of trying by turning the vehicle off and on. The following morning I contacted the Royal Kia dealership and told them of my issue and they informed me this was a known recall issue that had recently been discovered; they had the vehicle towed to them the same day. They...

I started my EV9 tonight and the main instrament pannel would not turn on. I was able to drive but could not see my speedometer or any other safty information on the screen. I was not notified about the recall until filing this report.

My family and I were driving down a busy highway at speed in the middle lane, the vehicle suddenly jolted forward and lost power. Dashboard reported electrical system failure, contact service. Vehicle was recovered to dealer who has been unable to resolve issue and KIA unable to diagnose the root cause of the problem. Very dangerous.

I was driving down the highway at approximately 60 mph with approximately 40% charge to the high voltage battery. While moving the car suddenly stopped accelerating and switched to neutral automatically. The instrument panel provided no audible alerts of a problem and in relatively small text stated "check electrical system" The brakes and the rest of the car's electronics worked such as turn signals and warning lights. We were able to coast and pull over to shoulder of highway and stop safely, but losing acceleration in middle of highway suddenly was very scary. Car is currently at dealer awaiting to be diagnosed.

On Oct 11th the vehicle failed to fully charge, stopping at 69%. I heard loud and repeated clicking from the undercarriage. On Oct 12th I received an email / system notification “ A suspected condition with your BuddyNine’s Battery Management System has been detected. Charging has been limited. A full system check is recommended. Please schedule an appointment at your Kia dealership as soon as possible.” On Oct 12th I received a critical warning in the Kia app: “ Your EV Battery has a critical issue. Contact Roadside Assistance (844-886-9411) as soon as possible.” I took the car into a Kia dealership on Monday Oct 14th and they have had it for 23 straight days. I have received conflicting information about the underlying cause and have not received an estimate for when it will be repaired.

The contact owns a 2024 Kia EV9. The contact stated while driving at highway speeds with the cruise control activated, the instrument panel went blank. The contact stated that when the instrument panel returned to normal operation, the vehicle quickly accelerated without the accelerator pedal being depressed. The contact immediately deactivated the cruise control and the vehicle returned to normal operation. Since the initial instrument panel failure, the failure persisted while driving at various speeds. The contact stated that the instrument panel intermittently flashed on and off and occasionally there were several warning lights illuminated after the instrument panel regained normal function. The manufacturer was notified of the failure and the contact was provided a case number. The contact was also informed by the manufacturer that the vehicle was not included in NHTSA Campaign Number: 24V757000 (Electrical System) which was linked to the failure. The vehicle was not repaired. The...

Main instrument panel in front of the steering wheel went blank; could not see the speed, charge status, or anything other than the gear. Turn signal indicator did not flash or make noise. The entertainment screen was not impacted.

Main head display in front of driver is blank. No live driving information is displayed, speed, state of charge, etc. This has happened 3 separate times at this point. So far, leaving the car turned off and locked for an undetermined amount of time (over 30 minutes?) has resolved the issue as the next time the car is started the display functions as normal.

I turned on my car and the screen did not turn on. I couldn’t see my speed or did not know if my turn signals were actually on or not.

Instrument cluster at steering wheel column went black. Cannot see driving speed , odometer, and other necessary safety status prompts. Requires shitting car off and turning back on to restore cluster. But it has failed multiple times since.

Half of digital dashboard not working. Unable to see speed of the vehicle.

The drivers display went blank. There is one indication so speed, break settings, turn signals or any of the safety related items such as blind spot, collision warning ect.

The main instrument panel went black just shift indicator is visible. Did not know how fast i was going. No warning messages or lamps came on prior to not coming on.

Gauge cluster completely blank after successfully starting the car. Happened twice in two weeks. No speedometer, no battery level, no safety features available, no audible turn signal

Vehicle powered on, while DRIVING, instrument cluster is blank. Cannot see speedometer- huge safety issue

My wife turned on the car after it had been parked for a few hours and the primary instrument cluster display (that contains critical information such as speed) was blank. There was nothing she could do to reenable it. This seems to be the same issue found by many other EV9 owners here: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I am reporting a critical safety issue with my KIA EV9. The vehicle's information screen, which displays essential driving data such as vehicle speed, cruise control status, advanced driving system indicators, lights, and signals, has malfunctioned. On two separate occasions, the screen went completely black while driving, leaving all critical driving information inaccessible. This malfunction poses a significant risk to my safety and the safety of others, as I was unable to monitor the vehicle’s speed or system status while driving. Availability for Inspection: The malfunctioning component (information screen/system) is available for inspection upon request. Safety Risk: This issue compromised my ability to safely operate the vehicle. Without visibility of the speedometer, driving system indicators, or signal lights, I was unable to monitor crucial driving functions. This increased the risk of speeding unknowingly and reduced my ability to respond to surrounding traffic, creating a dangerous situation on the road. Reproduction...

Each time, the digital instrument panel (where the gauges are displayed) goes almost entirely blank. It’ll restart after the car sits while off, but we’ve had to drive without the instrument panel telling us how fast we’re going and whether the turn signals are on or off. This has happened twice now. Twice I have had close calls with forward collision braking. The warning comes on but the automatic breaking does not occur.
