Turn signal, the turn signal just gs out and ds not work. This is a know issue with kia. I have almost bin hit several times do to this. I have 2 exact cars and they have both the same issue. You cannot just have the bulb replaced, the whole headlight asembly has to be replaced, the front bumper has to be removed to replace the headlight asembly, very costly, this is not so much the cost but more of a safety concern.
