Khem; If I were you,, I would find out if my state has a "Lemon Law" (mine does) and read up on it. My state's law is something like you can demand a refund or a new car if yours has been in more than 3 times for a specific recurring problem within the first year. Especially if it's been kept overnight. Sorry I can't be more accurate, but thankfully I have never had to invoke it. And it's mighty rare for any dealer to get it get that far around here. Your dealer's casual (and insulting) response makes me think your state has no such law. With it, dealers and manufacturers are HIGHLY MOTIVATED to fix your car properly the first time. Years ago dealer problems could be resolved by a regional office of the manufacturer, Ask about it. Mention "Lemon Law" and how badly your state needs one. It's not our problem to diagnose Ford's problems, but they DO have records of batch numbers, So you can ask--and tell us! BTW: Doesn't the C-Max have a separate 12V battery system for things like the lights and starter? Is that what failed? Sorry to be such a noob, but we've only had our car for 4 days, and I was barely able to pry her out long enough to set the radio presets. :) Bob
