Wife started the car today after work and the radio was completely dead and the blinker function did not make any noise when activated. She turned the car off a restarted a couple of times and everything came back on. Has anybody experienced this or have an idea what could have caused it? I am thinking there may be a short somewhere but I thought I would see if anyone had this problem. The car is still under warranty but if the problem isn't happening when the dealer inspects it will does me no good. Any help would be appreciated.
