I purchased my Cmax on 11/01/12. Except for trips, the car is always garaged and I check nightly for any lights etc. which may be on in my pitch-black garage.
Failure 1, on 11/08/12 with mileage of 998: Completely Dead, no lights, nothing came on. Called Ford Road Service, got jump. Not taken to dealer, as I was in the middle (Winslow Az) of a road trip from San Diego to Texas for the USGP.
Failure 2, on 01/19/13 with mileage of 4359: Completely Dead again. Called Ford Road Service, got jump. Took to dealer, battery replaced.
Failure 3, on 02/26 with mileage of approximately 4980: Completely Dead again. Called Ford Road Service, got jump. Not taken to dealer.
Failure 4, on 03/02 with mileage of 5050: Completely Dead again. Called Ford Road Service, got jump. Took to dealer, no draw found. After keeping the car for several days, the agency couldn't duplicate the failure.
So I am still waiting for a fix.
