2024 KIA EV9 Unknown Or Other Problems

Car stopped working and wouldn’t start. I was told there is an ICCU failure. There is a back order of ICCU for this vehicle and unknown date of repair.

When driving at speeds 60+ mph, EV9 steering wheel and center console vibrate consistently even on newly paved smooth road(s). I have taken it into two different dealerships for resolve twice within the first week of ownership. Both dealerships checked tires, mount and balanced the ones that were off and sent us on our way. The steering wheel and console vibrations persist. I have taken it back in and reported that the issue hasn’t been resolved. They noted it on the service order but did nothing further in an effort to resolve the issue. This is a well known and documented safety issue on NHTSA complaints and several Facebook owner groups for the EV9 across the world.

Description of the Problem: While driving my 2024 Kia EV9, the vehicle suddenly jerked and displayed a “Motor Control System” warning on the dashboard. The Kia Access app showed diagnostic code P0A4100 (MCU_R – Motor Control Unit fault). The issue causes the vehicle to hesitate and feel as if it loses power momentarily while in motion, creating a serious safety risk for me and my children. System/Component: The failure involves the Motor Control Unit (MCU) / electrical drivetrain system. The vehicle is available for inspection upon request. Safety Risk: The vehicle’s jerking and power fluctuation make it unsafe to drive in traffic, especially with children on board. It gives the sensation of being rear-ended and raises concern of potential stalling or loss of propulsion. Reproduction and Dealer Confirmation: The problem was reported to Sons Kia in McDonough, GA. The dealership initially inspected the vehicle on October 24, 2025, and returned it on [XXX], claiming the issue was addressed. However, the same warning and behavior reappeared less than 24 hours later ([XXX]). Inspections: The vehicle has been inspected by the Kia dealership service department. No outside parties (police or insurance) have inspected it yet. Warnings/Symptoms: The first warning appeared on [XXX], with the “Motor Control System” dashboard message and a corresponding alert in the Kia Access app. The issue continues to recur despite service.

A rear seatbelt indicator in the dashboard is broken, and it persistently indicates that (a) a passenger is in a rear seat; and (b) the passenger's seatbelt is fastened. This occurs even if a passenger is not in the seat and the passenger's seatbelt is not fastened. It is unclear whether this is strictly an electronic error in the dashboard, or if the seatbelt itself does not function appropriately. Kia has unsuccessfully tried to fix it twice, and the service department reproduced the problem by simply turning on the vehicle and seeing the persistent light. The local Kia service department says they are not trained to fix many EV problems, so corporate has to be involved, but corporate has not provided material assistance. Corporate has been informed in writing several times of the issue, including that this is a material safety issue, particularly since the vehicle is marketed toward families where a seatbelt indicator may be relied upon by drivers, and it's unclear whether this is strictly an electronics issue or a seatbelt functionality issue. Corporate acknowledged receipt of communications in which they were asked if this has been reported to the NHTSA, and they ignored both requests.

Vehicle suddenly slowed, with the same force at regenerative braking, to 30mph. Vehicle would not go any faster, changing drive modes, pedal to the floor, anything I tried did not work. Was in the middle of a 55mph road and was suddenly moving much slower than traffic with nowhere to pull off the road No warnings, no lights, nothing to indicate that I saw to show there was an issue. Dealership could not replicate and found no error codes.

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

I have persistent vibration issues with Kia ev9. It is very much a risk as it causes concentration issues while driving. My tires are worn out at less than 10k. Looking at the forum and reports a lot of folks who have EV9 are facing the same issue. Is there a investigation which can be looked into as this can be a safety issue due to vibration as well tired being worn as well.

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

I am experiencing significant and persistent vibrations at highway speeds (60–75 mph) in my 2024 Kia EV9. Despite multiple dealership visits and repair attempts, the issue remains unresolved. The vibrations cause noticeable discomfort and potential safety risks, especially on long drives. Timeline of Events & Repairs: 1.First Visit to Kia dealer (Dec 24): The dealership performed a tire balance and determined one tire was defective, replacing it. Vibrations persisted. 2.Second Visit (Jan 25) The dealership replaced the remaining 3 tires 3. ThirdVisit (Feb 25): The dealership identified three wheels with lateral runout and replaced them. They also performed road force balancing, reportedly bringing all values below 16. 4.Test Drive (Feb 25): After picking up my vehicle, I drove on the interstate and found the vibrations had worsened, now starting at 60 mph instead of 70 mph. •A third-party wheel shop inspected the wheels and found the fourth wheel (not replaced by Kia) was defective and out of round. 5.Dealership’s Response: Despite these findings, Kia dealer dismissed my concerns and referred me to another dealership for a second opinion. They also stated that third-party evaluations are not accepted, creating an endless loop where I cannot get the issue properly addressed. Safety Concerns: •Vibrations impact vehicle stability and driver comfort, especially on long trips. •Extended driving with excessive vibrations may lead to fatigue, reduced control, and premature mechanical wear. •The fact that multiple components (wheels, tires) have required replacement raises concerns about a potential manufacturing defect affecting Kia EV9 models. Request for Investigation: The dealership has failed to resolve this issue despite multiple repair attempts, and their refusal to acknowledge third-party findings leaves me with no clear resolution path. I request that NHTSA investigate potential defects in the wheels, tires, or drivetrain system of the Kia EV9.

I brought the vehicle in to have recalls addressed on 12/30/24. Starting the next day we noticed the car was weaving without any steering, but thought it might have been icy road conditions and waited to see if it reoccured. The car has since weaved intermittently, but has righted itself after releasing the accelerator. However, on 1/15/25 while traveling about 50mph, the car started weaving on its own and when the accelerator was released the car started to wildly fishtail. Called dealer and they agreed this was a serious issue and agreed to see car the next morning. Service tech said when they drove the car it did the same thing and that the troubleshooting recommended I change the regenerative braking setting to "smooth" and sent me on my way. I did not get even a mile before the car began weaving rapidly again on its own. Went straight back to dealership where manager wanted me to drive the vehicle again with the tech in car which I refused as it is not safe to drive. So he said if I was ok with it tech would take car out again but if it was just acting how regenerative brakes work, there wasn't much else they could do. When manager returned to talk to me, he said he ended up going with the tech and it did replicate the weaving action two times during that drive. The car is steering on its own weaving wildly left and right and imposes a great danger and no longer feels like a safe vehicle to drive.

The display for the instrument cluster is completely blank, or shows unrelated information after starting the car and shows none of the vital information about the car's operation or status. After leaving the car off for 30 minutes, the instrument cluster display began functioning normally. This was the subject of a 2024 October recall which we got dealer service for but the issue is not resolved.

Car was new with 1,002 miles on odometer and with me for 3 weeks. The 12 volt battery died and needed to be replaced. This vehicle uses the 12v battery to start the electronics for the car which then enable operation of the car. The failure of this battery left the car without any power and it needed to be towed from my garage to the dealer. This is a common issue with Kia and Hyundai electric vehicles.

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.

Dashboard shows a message" Stop vehicle and check brake system", vehicle doesn't pass over the 10 mph. On the KIA access APP I have all this 6 Diagnostic Issues : FR_CMR C28B981, FR_CMR C164286, ADAS_DRV C28B086, ADAS_DRV 28B986, ADAS_DRV C28B881, ADAS_DRV C164286. Dealer was unable to fix the issue, they state that it fix by itself. Also I have a safety Recall SC326

My gauges stopped displaying any information outside of the gear selection. I had no Speedometer, or acess to any of my safety features. This has happened twice and gauges will turn on again on the next drive if sufficient time has passed.

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.

Display/instrument cluster not functional when turning the car on after overnight charge to 80%. User profile display functions and car can shift into gear, although no speedometer available.

Left screen where odometer should show become blackout at the middle of my driving. Went to drive for 200 miles without odometer and other warning signs because the screen are all blackout, 3rd time happen. 1st was Gear also not emgaging and blackout screen 3 months ago, then same incident happen 2 months ago and then another incident with same reason for this month.

Display doesn’t come on when car goes on. Blind spot indicator, turn signal, speed display, nothing works. Car will drive but very unsafe without dash display.

Instrument panel went blank while driving. No digital gages available. No sound or picture when turn signals used. Had no idea how fast I was driving. The issue resolved itself after the vehicle was turned off and sat for a few hours. Have a service appointment for safety recall in addition to this and another concern.

Twice in approximately 6 weeks of ownership, when starting the car, the screen that displays the digital instrument panel for the driver has been blank with the exception of a single letter at the bottom of the display that indicates the drive mode of the vehicle (D). While in this state, the vehicle does not have any audio alerts (e.g. turn signal, blind spot warning, etc). Also, due to the screen being blank, the vehicle speed, remaining range of the electrical vehicle, and all other digital gauge data are unable to be seen. The screen portions to the right of the driver instrument panel (radio, android auto, etc.) are displayed when this occurs. If the vehicle is turned off and then allowed to sit for 30-60 minutes, when restarting the vehicle, the condition is cleared.

Digital Gauges Keep Failing

Dashboard screen is blank. Have tried to turn off and restart the car multiple times. can not see speed or other key information. There really needs to be a recall on this as soon as possible and some sort of a bulletin that the car is undriveable. It's the same issue described here. Car was fine until today. Assuming an over-the-air update must have caused a bug. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Yesterday I was nearly in an accident any my car’s horn did not work. It still doesn’t work. I called my dealer and they hadn’t heard of the problem in the EV-9 but added to my upcoming recall appointment. Not sure vehicle is safe to drive without a working horn.

The electric dash that shows speed, battery charge level, drive mode, and other safety features (such as camera side mirrors, whether turn signal is on) has gone blank twice. From research online, this appears to be a known issue that can only be resolved by disconnecting the 12v battery or stopping the car and leaving it lock for an extended period of time. This seems like a major safety issue.

Twice so far my EV9's main screen and the HUD have gone blank. This leaves me with no way to view my speed, alerts, etc. The only way to fix this, as far as I can tell, is to disconnect the 12V battery for a period of time and then reconnect it. It is extremely dangerous to not know how fast you are driving and to not have any other information, including driver alerts. And the fact that there is no way to reset the system without a great deal of effort (and a 10mm socket wrench) makes this extra hazardous.

Our display/cluster, indicators, sensors, emergency lights stopped working in the middle of the ride. Major safety hazard on highway. Have to turn off the car and wait 30-60 mins for things to start working again. I know this has happened with others and to us before but in that case display stopped working the moment you turn on the car. Can't see the car speed, or any other things on display.

Instrument cluster randomly will be blank. Which prevents the driver from seeing travel speed, battery level, etc.

Main display does not show speed, blind spot warnings, etc. it’s mostly blank. It shows that my vehicle is in park, reverse, neutral or drive. It’s blank other than that. Unable to monitor speed while driving!

The main display of the vehicle which shows Speed, Range, Blind Spot Cameras, etc - essentally all the critical vehicle information needed to drive - goes blank randomly. While the vehicle is driveable during this time, the driver does not know their speed, range, any other alerts/warnings that would typically be shown on the guage screen (including seatbelt warnings, mechanical failure warnings etc). During this time the climate screen and infotainment screens, which are seperate, function but the main guage screen does NOT. There is no pattern/predictablity as to when the screen will be unavailable. Further, it does not seem to return until the vehicle is parked and locked for an extended period (eg, several hours).

The control screen with speedometer, all the advanced driving systems has blanked twice. The car still drives fine, but I couldn’t tell how fast I was going or access any of the advanced driving features or warnings using a camera. I wasn’t even sure if my turn signal was going until I got out and checked. All the online forums advise to turn off and lock car for 30 minutes and restart, which has worked, but the first time it happened I was driving downtown and couldn’t tell whether any of my external signals were working. The second time (several weeks later) driving carpool. Get out and wait 30 minutes is not feasible. Because they were spaced rather far apart, I don’t feel like it’s a single software update issue.

Main digital display behind the steering wheel didn’t turn on. I had to drive home for one hour with no information on speed, range, cameras, proximity sensors, etc.

Kia is promoting the use of Digital Keys which rely on your phone and their app. Their app has been down for almost an hour now and it renders EVERY digital key to every owner, useless. While you can unlock your car in some cases, you cannot start your car. No matter what you do, you have to wait for their services to come back online in order for the digital key to work. The digital key also serves as a smart key. Smart keys immobilize cars without the key, to prevent car theft. What’s to say this in the middle of driving, the Kia app goes down again and causes an accident because you no longer can drive your car while on the highway ? I can’t drive anywhere as much as I would like to. I’m stuck at work with no ride and I’m not sure for how long. This is unacceptable.

The vehicle digital instrument cluster turned off and wouldn’t show speed or any other information. The central infotainment screen and the climate control screen worked while driving. The turn signals were not working while this was happening either. Tried to stop the car and start back again within a minute, but the screen never came on. Have pictures taken to prove it. Once we were at our temporary destination, car turned off and when we came back after an hour and restarted the car, the digital instrument cluster came back on and started behaving normally. Can’t reproduce the problem on demand, but happened a few times already.

When the car is turned on the speedometer display is blank. Further, the indicators of the car does not function as well. HVAC and info entertainment display worked as expected.

the main screen display showing speed, milage, camera etc randomly goes black and its not working. This affects working of turn signals, cameras on the side of the vehicle that aid in changing lanes and its overall a safety issue.

I leased my EV9, GT from Northstar KIA, NY. I got the delivery of EV9 GT on 3/29/2024. I started to notice that the car was not charging properly. After the whole night of charging it was charged like 3-4% at most. on the 3rd-4th day, the car started to make sudden abnormal sounds. I called the salesperson and dealership regarding the charging, and other issues, and told me to take it to the service center. I took the car to the service center on 4/7/2024, and I was told that the mechanic for EV9 was not available that day. Later that day I was driving to the shopping mall, and the car started to behave weirdly, after driving about 8-10 miles, right before the mall entrance, the car became very slow, it was not responding to acceleration. I was slowly able to pull the car to the parking. About 2-3 hours later when I started the car again, it started normally, all the signs were good, and as soon as I turned my car on the main street, about 3-4 minutes after starting the car, it suddenly stopped. Thank God, there were no cars right behind me. The power was on, but the car was not moving. I had to tow the car to my home since the service center was closed. The next day I called Kia roadside assistance and it is at a service center on 04/08/2024. I am an extremely busy physician and have small children in my household. I am deeply concerned about the safety aspects of this vehicle as it tends to shut off in the roadway while driving. This is extremely dangerous for me and my family. To my surprise, My dealer, Northstar KIA has no loaner vehicle. After my repeated requests, my salesperson told me to go to the service center and ask for a rental car. and also told me they would reimburse the rental fees. When I called the service center, they said they do not have any rental or loaner car. While I leased and paid for the car, I am without my car or a loaner car.
