2024 Kia EV9

Beginning sometime after purchase, our 2024 Kia EV9 (VIN: [XXX]) developed a recurring failure of the multimedia display system (head unit). The screen goes completely dark after approximately 5 minutes of drive time and only restores after a full vehicle restart. This failure occurred approximately 10 to 14 times before we brought the vehicle in for service. Critically, when the multimedia screen goes dark, the rearview camera display is also rendered completely unavailable. As the rearview camera is federally mandated safety equipment under FMVSS 111, this failure left us unable to use the camera while backing up on multiple occasions, creating a serious safety hazard to pedestrians, cyclists, and other vehicles behind our car. The vehicle was dropped off at Grand Kia (Wheat Ridge, CO) on XXX for diagnosis. The service technician disassembled and reassembled the head unit and contacted Kia Techline for an action plan. We were told a replacement part was on order. As of the date of this complaint, the vehicle has been out of service for over six weeks with no confirmed repair timeline and minimal communication from the dealer or Kia America. This is our second significant warranty-related repair issue with this vehicle. We are filing this complaint to create a federal record of a safety defect involving the loss of federally mandated rearview camera functionality, and to request that NHTSA investigate whether this failure pattern exists across other 2024 Kia EV9 vehicles. Requested Action: Investigation of potential safety defect involving multimedia/head unit failure causing loss of rearview camera in 2024 Kia EV9 vehicles.

What component or system failed or malfunctioned, and is it available for inspection upon request? Tire Pressure Monitoring System (TPMS) failed to detect or warn of any tire pressure abnormality before or after the blowout. Following the blowout, the vehicle’s diagnostics screen displayed “All Systems OK” while the instrument cluster simultaneously showed a “Low Tire Pressure” warning. How was your safety or the safety of others put at risk? A tire blowout at 65 MPH on a highway created an immediate risk of loss of vehicle control, collision, or rollover. Two minor children were passengers in the vehicle at the time. The simultaneous TPMS failure provided no advance warning, eliminating any opportunity to safely reduce speed or pull over before the blowout occurred. The vehicle had been in my possession for approximately four hours at the time of the incident. Has the problem been reproduced or confirmed by a dealer or independent service center? UNKNOWN Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?UNKNOWN Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? NO

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.

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.
