I found your original post and it was eerily similar to mine. I have been struggling these past 3 weeks. I have a 2013 Ford Fusion Energi Titanium. It has been wonderful. My typical routine is to plug it in at night time and go on my merry way come morning. A few weeks ago I went to leave work and when I got outside I couldn't get into the car. It was dead. My first move was to chance the key FOB battery. That wasn't the problem. I figured out how to open the door with the backup manual key in my fob and I got a jump. I was able to make it home. The next morning, dead. We took it to the dealer. He said he refreshed the modules. Started up fine. Took it to work. Came out at the end of the day, dead. Needed a jump. Took it to the dealer again. They had it for 5 days. I told them to pay attention to the sound of the fan running in the rear. It doesn't seem to stop and I thought this might be draining the battery. I told them about my charging routine so they could try to replicate the fault. They said they tried to replicate the fault and it wouldn't fail they also said they went ahead and reset the modules again. I picked up the car and had no problems except I ran an experiment. I did not charge my car for days. It ran and restarted with no problems. Last night I charged my car. This morning it was dead. I believe the fault lies somewhere in me charging that battery in the rear and some fan or some element is not shutting off when the charging is complete.... or something. I am furious at this point because I can't go on having to jump my car whenever I want to use it or whenever I want to charge it. I didn't pay for a car that has capabilities I cannot use. I am driving around with jumper cables in my passenger seat because I can't open the trunk when it's dead. I also am not locking my car for now because I am sure it will be dead when I go to use it this afternoon and I don't want to go through the trouble again of using the manual key. Can anyone offer insight? I am about ready to call and yell at the folks at Ford, call my car a lemon and demand a new rear battery and components. I am frustrated. Thanks for listening. Any insight or advice is appreciated. Also, is there an override to getting my car into neutral at all? That would be helpful when dead if I am in my garage...
