Ok so I pull in the driveway with my wife and we end up sitting in the car talking for about 15 minutes with the car off but with the key turned to the on position so that we can use the heated seats. We had the radio on and the lights were also on. Well, after about 15-20 minutes my display flashed to check the advancetrac system. Then my radio started acting weird like it was searching for a cd and then it just totally turned off and wont turn back on. My headlights work but my fogs dont. The car willl not start up or crank at all for that matter. Can anyone please help me. Thanks in advance guys.
