I have a 2008 pontiac g6 basic and I am having a problem with it starting after I have had something plugged into the cigarette lighter such as my phone charger. When I go to jump it sometime I have lights show up after it is jump such as my service air bag light and my tire pressure light after it is shut off they go away but my battery keeps dying with something plugged in. If nothing is plugged into it it works fine but if there is then its dead. Does anyone know anything that can fix this problem. I have only had the car a few months it only has 70000 miles on it.
