Sorry to hear your C Max is being anything but Max. I purchased mine late April 2013 and really enjoy the vehicle. It drives well, gets average of 45 MPG and is very comfortable. Other than a few recalls and a dead battery. The battery went dead due to some systems not going to sleep when I turned to the off. I called Ford Roadside Assistance and they sent a truck and jumped it. It started up immediately and I have not had that happen since. The other issues have come from the Sync. It is just weird at times. Maybe I need to have the dealership reprogram the system. I take it to Palm Bay Ford and find them very attentive to their customers. I drive 7.5 miles from my home to where I meet my van pool, usually 6 miles is battery and regen from the brakes. The highest I have seen on the gauge cluster is 52.3 mpg. Ford should take back your car and give you another as with the problems you have had I would say it is a Lemon!
