I have a 2013 fusion energi. We purchased it used with 6000 miles. In the beginning when we charged the car a full charge would show 19 miles on the graphic of the battery in side the car. Then it started showing 17 miles and now its showing a full charge at 14 miles. Has anyone else seen this ? It makes me wonder if the batterys arent taking a full charge or is this some type of calculation that changes with distance drived? Any input would be greatly appriciated.
