I have a 2014 Kia Optima EX. The other day someone noticed that my brake lights are not coming on. The Center High Mount (3rd) brake light is working just fine. I have replaced both tail light bulbs with brand new lights. I tried testing it with all sorts of configurations (all lights on, all lights off, turn signals on as I brake, etc) to see if perhaps it is a short. I checked the fuses that appear to be related to the lighting. Nothing seems to work. I have no idea what might be causing this. I have not done any customizations with any of the lighting or any other electrical. Has anyone experienced this? Does anyone have a wiring schematic? Any suggestions. I called a local dealership and the rep said he had not heard of this happening but if I bring it in he could have someone take a look...estimated cost starting at $100.
