KIA CARNIVAL HYBRID

POWER TRAIN

The hybrid car intermittently switches into EV mode after coming to a complete stop (e.g., at a traffic signal or after briefly stopping to pick up my child). When this happens, the vehicle does not accelerate properly once back on the road and feels stuck in EV mode, unable to accelerate beyond ~45 mph. This creates a safety concern when merging or crossing intersections.

2025 KIA Carnival Hybrid gets stuck in electric mode. This cause rapid draining of the electric vehicle battery, reduced maximum speed, and reduced acceleration. This has occurred while merging onto the highway. I had to pull over to the highway on ramp shoulder, turn the vehicle off and back, and then merge back until the highway. I have a video of it happening while picking up my kids from school, but it is too large to upload here.

The Kia Carnival Hybrid wouldn't allow me to accelerate, topping out at 30/31 MPH despite me fully pressing down on the accelerator. It has happened twice now (a few days apart) and can only be resolved by turning the car off and then back on. Compared to similar complaints logged on the NHTSA website, the difference is that this happened when it was roughly 50-60 degrees outside--not during extremely low temperatures as the other examples have described.

When pulling out onto the highway from my drive way the car would no accelerate when I pressed the gas, the car would not exceed 35mph, when caused me and my kids to almost get rear ended when pulling out since the car would not go..... the car will start to flash a " check hybrid system pull over safely" light and then the car will start to coast and I have to find somewhere safe to coast off to, to turn the vehicle off and then on again, it will run fine after that but it will eventually do it again... I have taken the car to 2 different dealerships to have it looked and and they tell me nothing is wrong with it
