I just bought a 2013 C-Max Energi with 93K miles. It is only getting about 2.1 KWH per charge with only 5-7 miles of range. This seems like a pretty huge loss from 5.5 kwh. Greater that 60% seems higher than normal for loss. I am pulling this data directly from the app. I took it to the ford dealer and they "can find nothing wrong" They tell me they have no way to measure the capacity or check the pack but since there are no codes there is nothing they can do. Anyone had any experience with this?
