I've had my CPO 2013 FFE for 17 months now. Never a lick of a problem with it. I had been having some annoying "Key Not Found" messages when trying to start the car for a few weeks. I assumed it was a nearly 5 year old Key Fob battery dying. It happened in both key fobs. I put off changing the coin cell batteries in both fobs. Yesterday, for the first time, I get a text message that the 12V battery is low, and please plug in the vehicle. I get out to the car about a half hour later, and it is totally dead, no dome lights, not instrument cluster, nothing. The battery voltage is about 6.5V, I plug it in to L1 EVSE. This morning, still dead, battery voltage dipped to under 5 volts.
I went over to a Ford Dealer, and bought a new battery (BXT-67R). Easily changed out the battery in about ten minutes. Everything is back on.
My build date is October 2012, so this seems reasonable for the original 12V battery to last nearly 5 years.
This was by far the easiest battery swap I have done in my entire life. No corroded terminals, no non-budging bolts, it wasn't snowing, or raining, or 10 degrees out. I'm quite happy with how it worked out.
The only part that puzzles me, is the very late "low battery" warning. It really didn't give me sufficient time to replace the battery before it had a fatal error.
In hindsight, I thing the inability to communicate with both key fobs aver the past few weeks should have been my warning that the battery was dying.
