I'm not sure what's going on. It's telling me to start stop the car when it's running and then it will turn off and go into accessory mode even when I'm driving that's dangerous. 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.

KIA K4 2025 UNKNOWN OR OTHER

The primary Dashboard of the vehicle stopped working (while driving the car) and i lost access to all important information such as speed, RPM, current cruise setting, milage, visual alerts for any driver assistance warnings.  The entire screen went black and showed âNO SIGNALâ in red text in the middle. It later came back after a few minutes. This issue has occurred 5 times so far and 4 of them being while driving the car within 1 week.  The dealer is confirmed this is an issue and recommended an entire dashboard replacement for the vehicle.  This is very unsafe because i cannot determine my speed or any other important warnings the vehicle may give me during my drive.  There were no warnings or symptoms prior to the first failure.

The car completely cut off while driving on the highway going 65 mph. This isnâ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 are unwilling to diagnose an issue with the vehicle unless it happens while they have it. I am putting myself and others at danger driving this vehicle. I contacted Hertz Auto sales where I purchased it and they directed me to contact Kia since I have a warranty. I plan on taking the car again but I can only hope the issue happens while they have it because this vehicle is VERY dangerous to be on the road and I have no other option than to be at the dealerships mercy.
