I have a 2002 Sonata. Very happy with it 'til the other day. Driving along and the car just died while on the road. All lights, radio and switches worked. Let it sit one hour and then able to drive home (.5km). Took it out last night and on the way home, again, died. This time I waited almost 2 hours (it's freezing here in Ontario, yikes!) and killed my battery trying to get it started. Tow trucked it home. Any ideas out there?
