Cutoff point is supposed to be closer to 32ºF, and if that was the issue, it'd say engine running due to outside temp. Sounds like your 12V battery is not maintaining sufficient charge. Do you take a lot of short drives or drive infrequently where the battery doesn't get a chance to recharge?
The funny thing is Ford just replaced the battery two weeks ago- A/S/S - Still not really working at all- Just says charging
What do you consider a reasonable trip to enable the battery to kick in A/S/S ? Its driven every other day at a minimum with a brand new AGM/760 battery
It’s not my determination. Some people don’t drive enough to keep the battery charged, this vastly predates engine start/stop technology. You’d have to describe your typical driving style, if you listen to the radio for an extended duration with the engine off, etc.
This isn't really a quantifiable exercise in how much do drive to equal a sufficient charge to active A/S/S - Will have the dealer check the rest of the charging system next week -
Mine has worked down to the single digits after using an external charger. After a year of ownership constantly dealing with this I’ve figured that the problem is that the system is not charging enough to support AutoStop/Start or there is something draining the battery excessively when it’s off. When the battery is fully charged it works all the time.
Same problem!!!!! Fords dumb ass can’t fix it even though I showed them the TSB!!! They contacted ford support and it’s been weeks!! I’m so annoyed! I get 100 alerts a month while driving and on app! Auto/start doesn’t work which is fine lol, but, it is annoying and I think is causing other electric glitchesMore 12v chargingsystem fun today even after the new battery 3 weeks ago -
Check that battery and all/terminal connections - Then find a new dealer- wow
Agreed!! It sucks!
