Thank you Allen. I just applied the "fix" you posted. I have been experiencing all the symptoms common to this issue for several months now on my 2010 FFH. Reset the battery age to year 1 and test drove the car around the block. It stayed in EV mode the whole way and avg'd 77mpg . It would not stay in EV mode before the reset. Instead the ICE would start immediately. It seems to be back to the car I purchased. My Fusion only has 105500 miles on it. I will watch it closely over the next few days and report any issues if they occur. Thanks again for all the help.
