Kia EV9 Electrical problems by year

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.

My 205 EV9 Wind with 24500 Miles left me stranded, the standard battery simbol that in ICE cards refers to the alternator, came on, I tried to get to the dealer about 20 miles in the way home, less that 3 miles after that the car lost power with just enough to move to the shoulder, I stopped, power the car off and tried turning it back on, no success, but this time I had enough power to park in a safer position. I took the vehicle on a tow truck that was called by the Kia Assistance.

I was sold a vehicle with a manufacturer defect. At purchase there was a loud wind noise coming from sunroof. I was promised a swift service department visit to realign the sunroof. At service visit ten days later the dealership replaced sunroof and threw electrical error codes B271100. After a specialist over rode the error the dealership claimed fixed and had me pick up the vehicle. The loud wind noise was still present. When I attempted to return the vehicle the dealership said I would no longer be serviced by...

The infotainment screen, including backup camera views, randomly glitches and then goes completely dark with no ability to view anything on the screen. The screen has been reset and software reloaded, but the glitch continues. Next, the screen was replaced but the glitch continues. This has been occurring since the beginning of June 2026.

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.

ICCU failure. Total and sudden loss of power. No acceleration. "Limp mode" activated for 5 miles before total shut down.

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...

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...

ICCU failure, code P1A9096.

At 4,000 miles the car had an electrical warning failure that required Kia to replace the gear reduction unit.

ICCU failure with 12v battery drainage resulting in inability to drive car.

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

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

[[redacted]] 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...
