I have a 2015 Ford Fusion Titanium Energi. Im wondering if there is something wrong with the EV Battery system. I live in western washington state, with mild winters and temps averaging about 40-45 F. The battery only charges to 11,12, sometimes 13 miles. (Sometimes only 9 miles). My fusion has very low mileage of 27k. I thought these were supposed to have a 20 mile EV range??? Any advice, thoughts or input appreciated.
