Well, I went on a trip for 2 weeks so my 'stang wasn't running for that long, when I come back I find that I can't open the door with my remote and the car doesn't start. Is this common? I jump started the car and left the car running for about 3 hours and I haven't had a problem since but is my battery bound to die again or am I all okay? Just wondering if I should buy a new battery or not.
