This may sound weird, but it could be your throttle body is beginning to have problems. These cars are drive by wire and there have been issues with earlier Fusion throttle body’s going dead in the middle of driving (search the forum for that problem). If your vehicle still has the original ones, it is most likely it. I replace both my Fusion Hybrids throttle bodies a few years ago after finding out the original ones sudden stop and acceleration problems. They original Ford ones are inexpensive from the internet for $55 and really easy the replace, just 4 bolts. Do the research first, if not it’s only $55 to replace.

Hi Everyone. Joined this forum after reset battery age to 1st year. I have had this same issue of barely going ev mode on my 2010 Fusion Hybrid for over a year. I have asked myself many times is that how Ford’s hybrids last, 9 to 10 years? Then it just turned into a regular car and have to haul the extra battery weight for the rest of its life? have also searched if the Toyota Prius has this problem, nope but different problem. I have searched for this Fusion ev problem over a year all over for info, but got none till last week. I always felt there was nothing wrong with the battery and it had to do with something Ford had put in. I have followed everything Allen had described. I could not get a laptop, so I haul my all in one Lenovo 23” inside the car to do it. I have two 2010 Fusion Hybrid (since this post takes care of the hybrid problem I am going to get another one 2011 $9000 with 20k miles). One Fusion with 96k miles and the other at 165k miles. Set both back to 1st year battery age. Now the ev mode will stay engaged up to the middle bar. That put a big smile on my face and some hollering. Finally got my hybrids back! Also I was able to programmed 2 extra keyfobs (from eBay with used Ford oem chips, but after market blank key blades) for one of the car, because the car came with only one key at the time it was purchased used. Both the hybrids drove/accelerate about the same now, even with the mileage difference. I also want to personally thank Allen for this post (also the reason I joined this forum). Thanks allen84! I also want to donate to your PayPal, let me know how.
