I have a 2006 Sonata gls have had 18 months it has 78,400 on it with a problem ( interminent), that has me lost,every once in a while after shutting the car off when I go to start it, when i turn the ignition key I have no power, to anything. After several minutes power will come on,usualy after checking connections and fuses,that sort of thing. this untill yesterday only happened 2 or 3 times in 18 months, yesterday it happened twice, I resorted to disconnecting the battery and waiting a minute and reconnecting that would resolve the issue. Just wondering if anyone else has had this problem,or may know whats causing it? Thanks
