Kia EV9 Engine problems by year

for myself and surrounding drivers. I was forced to maneuver the vehicle out of traffic while it was rapidly losing propulsion capability. The vehicle is currently at Berwyn Kia in Berwyn, Illinois for diagnosis and repair. I am reporting this incident due to the clear safety implications of a sudden loss of power during highway driving operation. A failure of this nature poses a risk of collision, especially in high-speed or congested traffic conditions. I am requesting that NHTSA review this issue as part of its ongoing monitoring of Kia/Hyundai/Genesis Integrated Charging Control Unit (ICCU) failures and related safety concerns. Thank you for your attention to this matter.

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

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.
