I have a 2011 chevy malibu and the other day went to start it and it started but seemed a little hesitant then the next day won't start without a jump. Every time you turn the car off you have to jump it again. Took it to oriellys they tested the battery it was fine but alternator was bad. Replaced it with a new one and car still won't start without a jump. Not sure what is going on with it. Any ideas on what could be the issue?
