problem with interior lights
First thing I'd do is check all the fuses. One might be compensating or something.
so you still have a warranty on the car?
check by your dimmer for your interior lights it should be on the left side of your steering wheel towards the bottom of your dash depending on your type of car
if u have warranty then get it covered.
it is the case of faulty fuses and switches. http://kia-rondo.net/
I had the same problem on daughter's 2007 Kia Rondo and it was as Adam suggested the dimmer/night light switch.
