My wife's 12 Edge for the past year and a half has been displaying on occassion, but now more often, a battery saver message on the center music screen, and also a "Check Charging System" in the main display screen. The Battery Saver message diplays when I turn on the ignition before I start it; the other check charging system message does not. When I turn off the ignition I get two messages. The center music display displays "Battery Saver Start Engine Or Turn Off Ignition" and the main display displays "Turn Power Off To Save Battery." In the past two years I have replaced my Duralast Gold battery with a 5 year warranty, twice. Both times have happened when it started getting cold(35° or colder). I never let the car sit for more than a day without starting it, letting it run, then most of the time driving it around for a bit, so the car isn't sitting in the cold draining the battery.
I have taken the car down to AutoZone and have had them check both, the battery and the alternator. When the batteries have gone dead they have replaced them every time no questions asked. This time that this is happening, I have taken it down and had them check both the battery and alternator and neither one are bad or look like they are getting closer to going bad. I don't have DRL's, Auto headlights, or any accessories plugged in inside. Everything inside is LED and nothing is ever left on. I haven't taken it down to Ford because every time I do, no matter what premium warranty I have, they always try to charge me an arm and a leg for everything that could possibly get them some extra money. It hasn't gotten to bad like the last two batteries but who wants their wife and baby to go get in their car when it's cold outside and then it won't start. I've tried resetting the battery numerous times, but with no luck. I really wanna be able to fix this myself instead of having to take it into Ford. Any help or ideas would be greatly appreciated.
