2024 KIA EV9 Complaints

Battery Management System - Critical EV Battery Warning This vehicle has been back to the dealership for repairs multiple times. Including needing to swap battery cells and wires around.

The vehicle was being driven on a highway when it became unresponsive to input from the accelerator pedal and the car's dashboard indicated an electrical system failure. There were no indications of problems with the car before the electrical system failure warning appeared. The car coasted to a stop on the side of the highway, where it was disabled (i.e., it would not shift into drive or reverse). The car was towed to a Kia dealership, where it has been for more than five weeks. The dealership replaced the ICCU but that did not resolve the problem and the car remains non-functional. The Kia dealership is waiting for the delivery of additional backordered electrical system parts to see if they resolve the problems.

1. When I go over bumps, the car behaves as if it's about to lose control. It porpoises and at one point it feels like you're about to lose control of the vehicle. 2. We have taken the vehicle to the dealer 3+ times now for the same issue. They claim that it's a glitch in the suspension but there is no know fix. At 55+MPH the vehicle starts vibrating and is completely different than issue number 1 above. They've tried balancing the tires but it has not been Successful. We're hoping to claim the car and Lemon through WI.

Received the following warning on 8/16 with 6987 miles on the car: Critical EV Battery Warning Your EV Battery has a critical issue. Contact Roadside Assistance as soon as possible. Car has been in the dealership for a week with "no estimated repair timeline" due to the battery cells failing. Car will not fully charge and is at risk of suddenly losing power and stopping, per the dealer.

While driving, the vehicle suddenly lost power and could not accelerate normally. The speed dropped and got stuck around 12–25 mph even when pressing the accelerator. This happened multiple times, usually during hot daytime conditions. It created a serious safety risk, and one time another car almost hit me from behind because my vehicle slowed down so suddenly. The dealer has inspected the car several times but said they could not reproduce the problem. Warning messages such as “Power Limited” appeared on the dashboard when the failure occurred. I also recorded multiple videos of the problem when it happened.

The instrument display panel goes black and you can’t see speedometer or hear turn signals etc.

The car battery cells are defective and would not charge above 60%. After faulting on electrical vehicle alarm instrument panel sometimes may show false battery state of charge.

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.

The contact owns a 2024 Kia EV9. The contact stated while driving at an undisclosed speed, the front driver's side seat detached from the frame. Due to the failure, the contact was unable to reach the brake pedal, and almost lost control of the vehicle. In addition, the contact’s mother and minor children were also occupants of the vehicle at the time of the failure. The contact was now concerned about the safety of the vehicle and was afraid to drive the vehicle. The vehicle was taken to the dealer where it was determined that all the seats inside the vehicle had detached from the frame due to fractured bolts. The contact was informed that the bolts needed to be torqued. The vehicle was repaired. The failure first occurred immediately after the vehicle was purchased. The contact stated that the failure reoccurred. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 6.

When traveling at highway speeds the rear suspension is not capable of handling road imperfections. When a pot hole or other disturbance occurs, the rear end of the vehicle violently porpoises and swing back and forth. This is made even more obvious when taking a long sweeping curves at 55 plus. It causes the entire chassis to become very upset. I have never had a car do this.
