Another non-standard failure. I have a 2013 C-Max Energi purchased on March 17. Currently has 1200 miles on it. It's been performing beautifully since we bought it and around 1000 of those 1200 miles have been entirely electric. This morning my wife took it to the grocery store (round trip 9 miles). Tonight, around 7pm, I found it totally dead. I had no experience with this but a quick search found several references to the 12v battery and ultimately to this forum. Reading all 36 pages was informative and those of you who've been fighting this for months have my sympathies! I put a charger on it and very shortly a lot of relays started clicking and the car started to come back to life. It took about 10 minutes (I'm charging at 15 amps) before the J-1772 came back alive and the EVSE kicked on. I don't know if it never finished charging this morning or what. We always plug it in when we park it. An interesting, probably unrelated issue. 5 days ago I downloaded and "installed" a small program from Ford that was supposed to record the current MFT software versions on a USB drive which I then uploaded to the Ford Sync site. The description indicates it didn't actually install anything in the car, just read some data. The day after I did that the car wasn't warmed up in the morning and I found all the GO Times were gone. Furthermore the myfordmobile site/app wasn't getting updates from the car. The reason I went out there tonight was I found another post that said pulling fuse 67 would "reboot" the cell-phone module and hopefully get it talking to the Ford cloud again. Not understanding what I was seeing when none of the interior lights worked, I popped the fuse anyway. After I got the charger on the 12v battery and the car started coming back to life it did, indeed, send an update to myfordmobile. But it made me wonder if that cellular modem was in a looping state and that's what killed the battery. I'll talk to my dealer about TSB 13-5-1 but while we do make lots of short trips (it's rare for us to exceed the 25 mile limit of the EV battery), we don't have high electrical loads. The climate system is generally off and the only thing plugged into the USB ports is a thumbdrive of music. Anyway, a data point for an Energi with the large touchscreen. --Rick
