I'm having an issue, again, which was corrected at the dealer the first time after a warranty repair. My repair issue was with the automatic windows malfunctioning and ford "hot lined" a patch to correct the system program error. This patch, which I assume contains a full and correct program update took care of the windows as well as correcting displayed range from 484 to 610. This also brought my actual driven range from 480 to 668! I was experiencing about 32mpg however and am once again. I will add...if you're having to work hard to get 40+ mpg, there is a definite issue. The ford energi with decent driving patterns according to the driving coach should get 580-620 on fuel alone without a single charge.(period) With everything functioning as it should be that has been my experience and with charging I push 648-672 on one full tank after 1-2 charges home/work. With current and obvious issues apparent to me I'm getting 460-480 with no change in driving style! PLEASE help me Ford!
