I've had my 2016 Sport age 3 CRDI for just over a year. When I first had it the head unit screen would change from the welcome "KIA" message to the clock display within a few seconds of starting the car. Recently it is taking anything up to a few minutes to go the clock display, the KIA welcome message flashes on and off during the process. While it's doing this it's not possible to use the sat-nav or any of the media services. The car was recalled in July for the fuse change but I'm not sure that the problem started immediately after. It's not a huge issue but irritating to see!
