What finally fixed it for me was the dealership replacing both the head unit and the touch screen. I still get an occasional phantom touch when using the bottom left touchscreen menu button when using CarPlay but it’s been mostly temper free. I did have to wait two months to get it fixed as the dealership had to communicate back and forth with tech line.
I am also having this problem. Has anyone found a solution? I also am having the issue where it will randomly beep and go from the home screen to the radio screen. Dealership has replaced the radio twice and it still does the same things. They say there is nothing else they can do and to contact Kia directly. Called twice no one seems to know anything or what to do.
