Kia K4

I took it to Kia a month ago for the same thing but they said they couldn't find anything, but it has to be something if I'm not the only one saying this is happening to their car. my car doesn't even have 8000 miles on my car.

The contact owns a 2025 Kia K4. The contact stated while driving at 40 MPH on several occasions, the vehicle stalled. The vehicle was able to restart but would immediately stall again, requiring the driver to wait approximately 10 minutes before the vehicle could be successfully restarted and driven. The vehicle was towed on one occasion and taken to the same dealer twice, but the dealer was unable to replicate the failure. The manufacturer was notified of the failure. The failure mileage was…

The car completely cut off while driving on the highway going 65 mph. This isn’t the first time it has turned off while driving. I had to pull over and put the car in park before it would turn back on. The error says Accessory Mode. I have taken the vehicle to Kia Dealership in Winston Salem but they told me they are unable to recreate the issue so they are unable to assist with the problem. The car turning off while driving has happened at least 20 times. I have repeatedly called Kia and they…

The warnings on the car all failed and I was lead off the road while going on a roundabout. This has trigged my car to completely lose all control and even though I was attentive to my steering wheel I still didn’t stop the car from leading me to that curb and off road onto grass etc.
