I drove the car less than 8 hours ago. Car started right up, no problems. Didnt drive it hard or abnormally. No lights or anything powered was left on. I came back down to start it and the dome lights and instrument panel display lights up and I can hear the fuel pump priming... However nothing else seems to work. The navi, dc outlets, etc do not come one and the starter does not attempt to crank. The keyfob doesnt seem to work right either. I hit unlock and it beeps twice but the locks do not move. The lock button does nothing... Except a long beep will be sounded from the car when the lock button is held on the keyfob. The rear trunk release is unresponsive from either the keyfob or exterior button. I tried to troubleshoot by hooking another car up by jumper cables and by unplugging the battery and then pressing the brake pedal to drain all power, reconnecting and attempting to start... Still no change. Could this still be a battery problem or is this most likely some sort of electrical/ecu problem? Any help would be greatly appreciated as my car is stuck in my garage and I have to work in the morning. Any ideas/suggestions? Thanks
