2024 Kia EV9 electrical problems

Filed Nov 1, 2026 · Electrical, Engine · IL

This car has had a series of electrical issues in the first year of use. 1. The main battery needed to be replaced 6/2025 2. The 12 V battery needed to be replaced 6/2205 3. 7/2026 There is an electrical issue that causes the right headlight to go out and all the indicator lights to be set-off, which prevents certain safety functions. This has been evaluated be an independent Bodyshop, which changed a part. Then 3 visits to the Kia dealer where another part was changed. After 4 visits and 2 parts, the problem occurred again. I've asked Kia to buy out the lease and they have not. This car is under warranty, but not fixed

The vehicle failed without warning while driving. In sequence, it displayed an electrical system warning, then a 12V battery error, dropped into reduced-power “turtle” mode, shifted itself into neutral, sat immobile while throwing multiple warning lights, and then lost all power completely. It had to be towed to local Kia for diagnosis/repair. Losing motive power while driving in traffic is a serious safety hazard that put the occupants and others around the vehicle at risk.

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.

BPM warning in the KIA app. Apparently, ICCU and battery failures are t known issues with the KIA EV9s.

[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

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.

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.
