I drove my car to a restaurant to pick up food. I come back in 5 min and my car refuses to start back. When i switch my igntion it just makes a whining sound and nothing happens. The Battery seems to be ok , as all lamps and indicators are working fine. I also found that the audio system got reset as i was trying to start the car. I removed all the key from the ignition and the lights were still on. My remote locking was not working any more. I had wait for a tow guy for a about an hr and the battery went down in the meantime. What can be the possible causes of this problem. The dealer today said it was a low battery, but when the car initially was not starting i had all the light and electricals on. Would this cause the Audio system to get reset and require the code to reentered again. Any advive or any past similar experience is appreciated. Thanks Collin
