2024 KIA EV9 Engine 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.

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.

I was driving and the car suddenly gave a number of error messages, and I could not drive above 40 miles an hour on the freeway. This was very unsafe. I had it towed to the dealership and they replaced the ICCU Unit, which appears to be a very common problem with Hyundai/Kia electric vehicles. The ICCU unit does not power the car. It should not have affected the car's performance.

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...
