On five separate occasions, while turning onto a high-speed roadway and attempting to accelerate to the flow of traffic, the vehicle suddenly lost the ability to accelerate. Despite pressing the accelerator, the vehicle would not exceed approximately 35 mph and then began to decelerate. During both incidents, a "Check Hybrid System" warning appeared, and I was forced to quickly pull over to the side of the high-speed road. The vehicle would only return to normal operation after it was turned off and restarted. This loss of power while merging into traffic created an extremely dangerous situation. Having three young children in the vehicle made the experience especially frightening, and I no longer have confidence that the vehicle can be relied upon to operate safely. Because this defect affects the vehicle's ability to accelerate safely in traffic, I am deeply concerned that it could result in a serious collision if it happens again. I took it into the dealership and the service center experienced the same issue. They thought they had resolved the issue and that it was a "one off" occurrence but it happened to me again just 3 weeks after the attempted repair. This time the engine light came on after the "Check Hybrid System" warning light.

4/6/2026 vehicle stalled in traffic multiple times, entered "Limp Mode", unable to accelerate after stopping or after deceleration. I had to press the gas to the floor to get the vehicle to move. While driving, if I had to brake or lay off the gas at all, the vehicle would not accelerate back to the original speed quickly. This put myself and my four children at risk of being rear-ended. I drove with the hazard lights on to Kia of Wesley Chapel Service center. The Battery Management System Warning displayed at the time of the stalling. The Kia Access App displayed the BMS Warning and code P0AA600 (High Voltage Isolation Fault). Initially, Kia of Wesley Chapel Service Advisor stated No warnings displayed and No historical or active codes found. I provided a screenshot of the Kia Access App showing the active BMS Warning and active P0AA600 code at 2:48PM on 4/8/2026. The Service Advisor maintained that they could not find any active or history codes. At 3:00PM the same day, the Kia Access App suddenly showed "No Issues Found". The code was obviously manually cleared. I filed a complaint with Kia Customer Care the same day (4/8/2026) and requested a Kia Technical Specialist be assigned to the case. On 4/12/2026, the original Kia Service Advisor stated "the history code has finally appeared which was the one presented in the screenshot but we cannot replace parts based off of a code that is no longer active unfortunately". He stated they would "keep driving and testing" to try and duplicate the issue. The Kia Access App shows the last trip was 4/7/2026 (the day after I dropped off the vehicle). Interestingly, the vehicle was not moved from the drive up lane at the Service Center until 10:40AM that day, after being dropped off at approximately 6PM the evening prior. I believe they could not get the car to move the evening of 4/6/2026. The vehicle remains at Kia of Wesley Chapel. I am sending the Motor Vehicle Defect Notification to Kia Corporate today.

While driving the car it will stick in the electric mode and not go back into gas mode. You will only be able to go up to 30-35 miles an hour and in order to fix this issue as of right now all I could do was have to pull over to the side of the road put the car in park turn it off and turn it back on. I worry that this issue will be even worse if I was on the interstate and my car was getting stuck in electric mode and then it’s a safety issue, especially since I have kids in the car. I’m majority of the time being a minivan. I have seen other people post on forms about this issue and it not being fixed by Kia

When the vehicle is idling, the battery refuses to charge, therefore, the car suddenly dies and makes it unsafe to pull over and dyes while driving, very dangerous and transmission doesn’t shift properly.

The car gave alert of "hybrid system failure" and showed a picture of a drained battery. After about 20 seconds, we were unable to drive over 30 mph. After about 30 more seconds, the car shut off and had to be jumped to work again. Luckily we were pulling over into a parking lot when it shut off, but were blocking the entrance. This is the 4th time this has happened in a couple of months since we bought the car.

Vehicle lost power and would not accelerate past 30 mph even when fully pressing down on the accelerator. After a few minutes a warning flashed to check vehicle hybrid system. Pulling over to the shoulder and restarting the car returned the car to normal operation.

Car would not allow me to accelerate. It seemed to keep me running only on the electric motor vs the gas engine (the vehicle is a hybrid). This has happened multiple times. The fix is to turn the car off and on again.

Temperature was 28 degrees outside. Car had 4500 miles on it. Car warmed up for 10 minutes before driving. At the one mile mark, it locked up at 31 mph and 1.4 rpm. It would not accelerate and it maintained the speed and rpm without pressing on the gas. The brakes did work. It lasted for another mile and then resolved. No indicator lights came on. The car did. It recognize there was a problem. It has not been replicated. It is available to be inspected. Not being able to accelerate above 31mph poses significant risk to both my family and other drivers.

Car would not accelerate past 30 or 31 MPH no matter how hard gas pedal was engaged. The RPMs increase, acknowledging the gas, but the speed stays the same. Stopping the vehicle and putting in park doesn’t fix it. This is particularly dangerous when going from city street to highway or interstate driving. It eventually self-corrects after about 5 minutes. We’ve experienced multiple instances now, and all have been in cold weather (<10° F).

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
