I have had similar problems 2017 platinum, buttons not responding, radio turns on full volume when going into park. Rear fan control not adjustable independently, black screen brick mode sometimes.
Always seems to come back eventually.
Told kia several times, they have updated the software at least twice, or at least told me they have. They are pretty useless. Ive also asked for updated facelift head unit as late as last week, got told it would be programmable to pre facelift.
Unless we find a wrecked/ totaled facelift and try it ourselves.
Or have to go aftermarket and loose almost all functionality with climate control and nav buttons through the screen.
