2024 Kia EV9 Electrical Problems

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.

[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)

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

Incident

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.

Incident

Sep 15, 2025

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.

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.

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.

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 to perform the recall repairs. The contact then received an email the next day that the dealer failed to diagnose the failure and that the failure would be escalated to a technician provided by the manufacturer. The contact then called the dealer where the information was confirmed. The contact was informed that the vehicle would remain with the dealer for three to four months. The dealer was unable to provide a loaner vehicle due to a shortage of available vehicles. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired and remained in the possession of the dealer. The failure mileage was approximately 12,000.

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 Under Virginia Lemon Law Under the Virginia Motor Vehicle Warranty Enforcement Act (Lemon Law): A vehicle qualifies if it is out of service for 30 or more calendar days for warranty repairs within the first 18 months or 18,000 miles. My EV9 has been out of service for 49+ days, meets mileage and time limits, and involves a major system failure. Therefore, my vehicle qualifies for relief under the statute. 4. Issues for the Arbitrator to Address The vehicle meets Virginia Lemon Law criteria due to prolonged inoperability for a substantial defect. Kia has not provided a comparable loaner or timely resolution. The vehicle poses safety concerns due to failed propulsion battery. 5. Desired Resolution I am requesting a full repurchase (buyback) of the vehicle, including: Full reimbursement of the purchase price (down payment, monthly payments made, taxes, fees). Any towing or rental expenses incurred. Cancellation of the finance agreement if applicable.

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

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.
