I own a 2006 pontiac g6. It was a graduation present from my parents. Ive never really had any problems until recently. My car battery keeps dieing and the radio wil click, like the cd changer goes through the 6 cd spots and then my car shuts off. These past few days, when i go to stick my key in the door to unlock it, my car alarm goes off twice. then stops. Ive never had this happen to me until two days ago. and now my door ajar keeps showing up on my radio, even though i got out and shut all doors including the trunk, hood, and gas lid. Still the light stays on, which keeps my light on saying there is a door open, thus killing my battery again. I love my car and i just dont know what to do. Im 2 hours away from home and at college, and these problems im having with my car is killing me...Does anyone have any idea whats going on??
