I have 7,000 miles on my Fusion, been driving it for a year. My wife and I have been competing to see who gets the best gas mileage each time we drive it. It has been normal to see the high 40's and mid 50's on drive of 5 or 6 miles. We are also accustom to see the battery level recede to about 1/4 when the engine kicks in. Normally it will charge to about 3/4 full and the battery will then take over.
On a particularly cold morning, I noticed the battery being full charged and the engine continued to run continuing to charge the battery. We use the "Engage" monitor on the dash. After driving about 5 miles the battery was still in full charge but not discharging. This also occurred with my wife when she drove it the next day. Our MPG was staying in the low 30's to high 20's. At times the battery would discharge and recycle but it was different from our past 11 months experience.
I took it to the Dealer-They informed me there was a recall and performed Field Service Action 14B03.
Drove for a week and while it was a little better, the problem was still there and our gas mileage is staying in the low 30's.
Not only that we were not able to get the EV+ to work. It was more intermittent but you could guarantee that it would occur several times a day.
Returned it to the Dealer-They could not reproduce the problem, said I probably had a lead foot and that 35-36 mpg is what would be expected during this time of the year. Mechanic also stated he had not ridden with me. They did get my EV+ working but I am still getting low 30's mpg.
I had this car during last years winter and it was a lot colder that this year, yet I did not experience the drop in MPG.
Wondering if anyone else has had this problem?
