center tail light replacement

kind of a pain in the ass on the sonata - here is a great free video showing step-by-step instructions on changing the center tail light (aka center brake light or third brake light) http://carcarekiosk.com/video/2009_Hyundai_Sonata_GLS_2.4L_4_Cyl./lights/center_brake_light

Usually these center mounted stoplight bulbs are accessable by removing screws from underneath the light.
