weak battery/alternator problems on 2009 Forester?
battery dies after a few hours of dome light being left on. I don't know if the car comes equiped with a cheapo battery, if the car has a known alternator problem or I'm just not checking something. I've always left lights on, door ajar, trunk open, forgot to wear pants to work, or left the dome light on many times in several other cars and if the battery was not approaching an anticipated death after 5-7 years then I would expect the battery to last at least overnight and still start the car. Not this one. Dome light killed it and tailgate doesn't close smoothly leaving the rear light on. Both drain the battery overnight. If I don't start it one day, it has a hard time cranking and might not start the next. Is this a known problem? I'm mechanically challenged; what should I go over before checking with the dealer asking for warranty work?
