I have 65k miles on my energi and over time the max range has slowly but surely started petering down. When I first got it, a full charge would show a range of 23 miles (highest I have seen it) but mostly around the 19-20 mile range. 4 years later today, the max range shows as anywhere between 9-11 miles. Whaaat happened???
Also, on a 240v charger, it used to take 1.5-2.5 hours for a full charge. Now, I leave it plugged in overnight and still 14 hours later it shows "75% charge". Charging around 4 hours gives me less than 20% charge. What is going on here? Is this a dud?
The dealer says he can look at it but it will cost me $200 to run diagnostics (even though I have Ford Premium ESP. Worth it?
