I have a high pitch whine coming out of the alternator area. It has been there for about a month. Today while driving around 50 the car suddenly died. DEAD.I got it to stop and with traffic and bad winter up here it was interesting. I put it in park and it starts great. Has anyone had this happen to them? Could it be the alternator? I don't have a clue how a car can just die like that considering I have a new battery.
