Something keeps draining my battery at night causing the car to not start in the morning. Once the car is jumped, it will run/start all day. I had it at the dealership for 2 weeks and they couldn't locate the problem. Battery is new and tests could and alternator also tests good. My personal feeling is that it has something to do with the automatic locks and also the interior lighting. The door ajar message will stay illuminated even when all doors are closed, keeping the overhead lights on until you clear the message. Sometimes, the automatic door locks won't lock the doors until you are 10 miles down the road. Any ideas on where to start to track this down?
