2024 KIA EV9 Woodbridge, VA

ELECTRICAL SYSTEM

We were driving in the middle lane, going straight approximately 25 MPH. The car lurched and almost flipped. We were able to pull over, the wheel was no longer spinning with the car and the tie rod snapped at a weld point. We could have been killed had we been going faster. My son was thankfully not in the car. I am desperately trying to get the car inspected but the dealership will not unless we pay. There were no warnings, but a whining sound began yesterday and we were on the way to the dealership this morning. Now there are warnings. There have been so many safety issues with this car. I will be filing 2 other reports for the seats.

2025 KIA EV9 Chicago, IL

ELECTRICAL SYSTEM

I am submitting a safety complaint regarding a serious incident involving my 2025 Kia EV9. The vehicle was serviced on March 1 at World Kia in Joliet, Illinois. On April 4, only four days after that service, the vehicle experienced a sudden and unexpected ICCU failure while I was driving. During my normal travel, in active traffic and at speed, the vehicle abruptly entered limp mode and displayed multiple system warnings. This caused an immediate and significant reduction in power, creating a hazardous situation for myself and surrounding drivers. I was forced to maneuver the vehicle out of traffic while it was rapidly losing propulsion capability. The vehicle is currently at Berwyn Kia in Berwyn, Illinois for diagnosis and repair. I am reporting this incident due to the clear safety implications of a sudden loss of power during highway driving operation. A failure of this nature poses a risk of collision, especially in high‑speed or congested traffic conditions. I am requesting that NHTSA review this issue as part of its ongoing monitoring of Kia/Hyundai/Genesis Integrated Charging Control Unit (ICCU) failures and related safety concerns. Thank you for your attention to this matter.

2026 KIA EV9 Las Vegas, NV

ELECTRICAL SYSTEM

While making a left turn at a four-way intersection, the passenger side front door opened the latch failed. This vehicle is equipped with motorized door handles that retract/flush when the vehicle is in drive indicating that the doors are locked. The door handles were retracted while driving the vehicle and making the slight left turn. During the turn, the passenger side front door opened and was a jar that could be indicated on the dashboard as well. This would put anybody at risk sitting in the passenger seat or causing an accident from the malfunction and alarm of the door. The vehicle was examined by a service department of a Kia dealership and parts of the door latch and or handle were replaced according to the repair order.

2026 KIA EV9 Greer, SC

ELECTRICAL SYSTEM

Car was driving find and suddenly check electric system message came in with a red battery indicator. The application for the car indicates an ICCU P1A9096 error code. ICCU errors seems to be common with Kia/Hyundai electric cars. Car went to limp mode and wouldn’t let drive it more than 45mph which it was dangerous in the highway. I was able to get the car into the dealer but the last mile the car was very limited in power with no more than 30mph. Radio, A/C and other accessories stop working

2024 KIA EV9 Winter Park, FL

ELECTRICAL SYSTEM

[XXX] Message says warning "check ev system". they then sent a letter saying it had to go to the dealer, or the car would need A tow potentially. I can't get an appointment as they are way too busy to do anything other than tell me they will get back to me, repeatedly stating they will do so in one business day. it has been a week. My wife is scared to drive the car. I think it is bogus as no recall has been issued. I have had the car for 19 months with no such warning. Two days after it shows up on the screen in the car i receive the letter. This is fishy. it is either a recall, or it isn't. if it is why is it not in your data base? The vagueness of the message is inappropriate, and it implies danger. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2025 KIA EV9 Beaumont, CA

ELECTRICAL SYSTEM

Component: Electrical System / Instrument Panel Speed at time of failure: [Insert typical speed, e.g., 65 mph] Description of Incident: My vehicle is suffering from an intermittent but total loss of the instrument cluster functionality while in motion. The display goes dark and is replaced by a "No Signal" message. This results in the immediate loss of all critical safety information, including speed, battery range, and warning telltales. This is a direct violation of FMVSS No. 101 (Controls and Displays). Specific Recalls/Campaigns Not Addressed: I brought my vehicle to Fiesta KIA (Dealer Code 53232) to address the following open safety campaigns which they failed to remediate: NHTSA Recall #24V-757 (KIA SC326): "Instrument Cluster Screen May Fail." This is exactly the failure I am experiencing. NHTSA Recall #24V-443 (KIA SC302): ICCU Software Logic failure, which poses an immediate risk of loss of motive power while driving. Service Action SA563: Specific logic improvement for HUD and Cluster stability. Dealer Conduct (Safety Related): Despite the vehicle presenting with a "No Signal" instrument panel—a catastrophic safety failure—the Service Manager (Anthony) refused to provide the previously promised loaner vehicle. He suggested that because the vehicle was not purchased at his specific dealership, his obligation to facilitate this critical safety repair was diminished. This resulted in the vehicle remaining on the road with unresolved, safety-critical defects.

2026 KIA EV9 West Palm Beach, FL

ELECTRICAL SYSTEM

Instrument panel goes Black while driving. Keeps flickering on and off while driving. Took it to a dealer and they denied the flicker, even though I have 15 videos of it. Dealer just gave us the car back without fixing the issue and told us to live with it. This is extremely unsafe as we go up to a minute without seeing anything.

2026 KIA EV9 Prairieville, LA

ELECTRICAL SYSTEM

I own a Kia 2026 EV9. We charged the car to 80% (we have reduced the limit to only 80%). The next morning there was no power to the car. The interior lights would not come on door handles would not work. I could not start the vehicle. I read on line of the 12v battery dying and ICCU failures. I charged the battery for 1.5 hours and was able to get the car to start. I immediately drove it to the Kia dealership on 01/05/2026. The service department stated they could charge the battery but had to further diagnose the problem. On 01/08/2026 the service department stated that the tech was "tinkering" on the car and would reload software updates and patches. On 01/09/2026 the service department informed me that the technician still does not know what is wrong with the car and the tech is off again today.

2024 KIA EV9 Bothell, WA

ELECTRICAL SYSTEM

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. To protect the battery and prevent thermal or electrical damage, the system must immediately limit propulsion or enter a reduced-power (“turtle”) mode without driver input. Because these protective actions can occur suddenly and without advance warning, they can restrict acceleration or vehicle speed during ordinary driving conditions such as merging or maintaining highway speed, creating an unexpected loss-of-propulsion safety risk rather than a mere inconvenience. This is equivalent to a faulty fuel gauge for a gasoline car but with more immediate and severe consequences Sudden Power Cutoffs: If a single battery cell's voltage drops below a safe threshold, the Battery Management System (BMS) will shut down the entire pack to prevent permanent damage. This can happen even if the dashboard shows 25% or more remaining, potentially leaving you without power while driving. Loss of Vehicle Control: A sudden shutdown can lead to a loss of power steering and braking assistance, which is hazardous in high-speed or heavytraffic situatio

2024 KIA EV9 Huntsville, AL

ELECTRICAL SYSTEM

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 driver’s view of critical controls and information, increasing the risk of accidents. Customer service from the dealerships has been unsatisfactory, with long wait times for repairs, lack of loaner vehicles, and repeated failure to resolve the problem. This ongoing safety concern remains unresolved despite numerous visits and repair attempts.
