I have a 2013 Optima hybrid EX. The buttons on the key fob work perfectly. The unlock/ lock button on the door handles work as well. When I get in the car and push the brake, you can hear the system make noise...when I push the start button it won't make the chime sound and the ready light won't come on even though the car actually starts. It won't let me shift out of park. If I use the shift lock release, I can drive the car as usual but my gas gauge, temp gauge, and hybrid battery gauge don't work. Even the cruise light doesn't come on but the cruise control works. The headlights work but the brights will not come on. Any ideas on what is wrong?
