My 2013 Energi has a similar issue, also with a 12v battery parasitic drain. Have changed the 12V about 1 1/2 years ago but didn't change the battery life setting in the Fusion software. People say that how the 12v is charged is linked to the age of the 12v battery life setting. A Ford TSB points to possible chaffing of (fan?) wire forward of 12v. Mine is fine. But, the TSB goes on to say if no chaffing, replace the TCU. My dealer changed the charging port. Got 15 miles on gage first charge, then 19. But, next time would not charge until I reset screen charge schedule to Charge Now AND started engine and shut down, Then, it began to charge to 22 miles. It appears that when the 12v depletes to the 11v area, the EV battery charge issues appear. My guess is that your EV battery is not the issue. So, have you had dealer diagnosis yet? So, I just got a FORscan tool and am trying to understand how to reset the 12v battery life setting. It's in the BdyCM - Body Control Module file, but I've not yet figured out how to change it. I don't know if it could resolve the issues I'm experienced. But, reducing the age of the battery will change the charging and some electrical draw parameters, so I want to reset it as per standard Ford protocol. By cycling the ignition on and off, and cycling the Sync "charge now" and "charge on schedule" buttons, my vehicle charged to 22 miles, the accuracy of which I confirmed by expending them and comparing with the odometer. But, when trying to charge after that, nothing I did would get it to charge. The ability to experience a charge to 19-22 miles is what leads me to believe the fault is not the EV battery,

Thank you all for your advice. It may, indeed, be just a coincidence that my issues started just as the modems were decommissioned. So, I will go to a dealer for a fix (same dealer which told me I cannot charge with a decommissioned modem). If it is determined to be a modem related malfunction, I'll not be happy with Ford for charging me to diagnose that. But, if it's not modem-related, the fix may be less expensive than a modem upgrade!

Muzicman, I also initially felt I would go without a modem upgrade, but now find my plug in vehicle will not charge. I tried resetting by disconnecting 12v battery, removing and replacing modem fuse, and trying to reset FordPass (but, I can't get FordPass to activate). Still cannot charge, and today's engine code is U0111 (first one I've received), "Lost communication with battery Energy Control Unit module A." Can you charge your vehicle?

Thanks for the hopeful news. I will try again tomorrow. Heretofore, the Charge Now in the vehicle has not worked. I'll try the circuit breaker and other work-arounds suggested in this forum. If I'm unsuccessful, it may be that my 2013 model has an early model system which is different tha 2014- models.

Sync sends me to FordPass for controlling vehicle, but also notes that there needs to be an embedded modem to control a vehicle. Anyway, I've been trying FordPass on my laptop and cell for weeks, and have been unable to activate it (I'm sure it worked prior to modem decommissioning).? Wife is shopping (on gas!) now with Fusion. When she returns, I'll see if I can do anything with the vehicle systems, as has been suggested here,

Agree. Process, as Ford tells dealers, should be .7 hr. But, as you mentioned, the dependent determinant is, "if one is a tech that has done this multiple times so is familiar with all steps"

Apologies for mis-spelling in previous message. I mistakenly touched return as I scrolled to proofread. Franny2016, I was told by a dealer that a dealer notice was issued in about early April informing dealers to cease modem upgrades until Ford resolves installation problems.

Thanks for advice on getting my vehicle to charge and its 12v not discharging. The lack of PV charging and the 12v battery discharge occurred simultaneously. I wanted Ford Hdqtrs to inform me of the effects a dead modem would have with my 2013. But, when Ford Customer Experience several times told me they would elevate my issue to the PV section but didn't, and several times after that told me I should go to a dealer for diagnosis. I was reluctant (because 4 dealers ignored my calls or claimed lack of knowlwdge) because I felt Ford Hdqtrs should first tell me what to expect with a dead modem, and I don't trust dealers messing with my vehicle in a diagnosis. But, just recently, I did visit a dsewaler, and itrs PV specialist said that I would not be able to charge and communicate witrh the PV systems. And, iut's my understanding that the 12v battery is charged from the PV system (including hybrid), not the engine. In any case, I will try the interventions suggested by CR08. BTW, my original 12v lasted for 7-8 years, and the cxurrent one is 1-2 yrs old. Thanks to all for inputs.

Thanks for contributing this information, folks. Some companies are appreciative of those who buy their new technologies when first available (some call these buyers, "early adopters"), but this seems not the case with buyers of Ford Fusion Energi technology when it was new in 2013! I would certainly be appreciative to hear from owners of 2013 Ford PV models.

I have a 2013 Energi, and Ford has not contacted me about decommissioned functions caused by decommissioning of the 3G modem. I found out about ther modem issue through forums after not being able to charge as well as experiencing other malfunctions in March 2022. I now have a non-electric Energi and no MyFordMobile or other way to communicate from within or outside the vehicle (and, FordPass will not activate for me); and, if I don't operate the vehicle at least every few days, the 12V battery depletes to a non-start condition. I am very, very unhappy with Ford. After numerous communicatioins with dealers and Ford Customer Experience, I am told that there is no fix for a 2013 modem at this time (also, a dealer told me that there is a recent Ford notice to dealers to cease doing the upgrade on 2014- models because there are problems with the upgrade). Ford has given me no hope for if and when my vehicle can function as it was designed. Meanwhile, after accumulating 2/3 of my total 58,000 miles in electric mode, I am relegated to only internal combustion miles, and my charger cord hangs unused. If others of you are experiencing a horrible lack of care and concern from Ford (no matter the model or year of your Ford E vehicle), I think we should consider a class action lawsuit. Here is my April 14 response to Ford Customer Experience telling me there is no fix at this time: " Thank you for responding to my concerns about the lack of functionality of my 2013 Fusion Energi as we initially discussed in our phone conversation. In the six times I contacted Ford Support, you are the only one of several who actually followed up after telling me I could expect a follow up from Ford. Although I appreciate your response to my concerns in our phone conversation, it should be self evident that the response does not address the serious fact that my vehicle does not function as Ford intended, and I accepted, when I purchased the vehicle in September 2013. I told you and other Support staff that I was not convinced that I first needed to have my vehicle diagnosed at a Ford dealership when, in fact, you at Ford corporate have technical specialists who could tell me (and should have told me in writing!) if my vehicle failure symptoms could be caused by lack of a functioning modem. Nevertheless, I went to a dealer for a diagnosis because you offered me no alternative even though I really wanted to talk to a Corporate PV specialist first. My experience trying to get information from dealers (prior to contacting Support) is that they either did not return my calls, or simply expressed that they did not have knowledge of the modem issue. The result of dealer diagnosis is as I expected--that the lack of a modem affects the ability of the vehicle to charge and communicate/transmit various functions internally and externally. Additionally, my 12V battery discharges to a non-start condition if the vehicle is not used for two days. So, although my Fusion has been a great vehicle for me for 8 years now, it has become a nightmare. And, this should not have been the case but for Ford management mismanagement. It was common knowledge for some time that Level 3G modem service would ultimately transition to Level 4G. But, Ford waited until November 2021 to inform some electric vehicle owners that the Level 4 transition would occur around March 2022. And, then only owners of 2014 and up vehicles were notified that they could buy a Level 4G upgrade kit. I NEVER RECEIVED ANY KIND OF COMMUNICATION ABOUT MY 2013 Energi! (And, I am told by a dealer that there is a recent Ford notice stating that there are problems with modem upgrades, and they should be halted until further notice). And, now, your message simply tells me that there is no compatible modem for my 2013 Fusion at this time. It is unacceptable for Ford to, essentially, leave me with a vehicle which will not function as intended as a PV, and to not communicate with me to admit this technical problem and express a plan for resolution. It is not AT&T which caused this situation. It is the negligence of Ford. It is my intent to seek to form a class action lawsuit based upon a "fitness for purpose" principle. I have unnecessarily spent too much time with dealers and Ford Support searching answers which should have been provided to me by Ford."
