Battery light came on (mild vent)
Today the battery light came on. And it stays on. Looking at the repair list that the dealership did when they got the car, battery isn't on the list. So my first guess (and hope) is that the battery is going bad, especially since it's been colder than usual.
My second guess is that it's a bad alternator, which I'm hoping not. I didn't plan to buy a reliable car, only to spend $400 fixing it 6 weeks later.
I'm going to take the car to get the charging system and battery tested tomorrow.
