I have been having problems with my electrical system. First the passenger door wouldn't lock. I disabled the auto unlock and most of the time it works now. A few mornings in the last month the Windows wouldn't roll down. Then the dome light wouldn't come on when unlocked. Tonight I went to get in and it wouldn't start. Jumped it and it started right up but the battery level indicator on the screen showed that it wasn't charging. I turned it off and it started again but still showing no charge on battery. I am going to see what it does in the morning but just hoping maybe someone has an idea why...

 

Your alternator might have failed so your battery died because your alternator is not recharging your battery. Take it to a shop and they can do a quick test on your battery and your alternator.
