George Hyma Posted September 11, 2023 Report Share Posted September 11, 2023 I have a 2022 Ford EDge. For three months the auto start/stop feature does not work. Ialso get messages that the batter goes into deep sleep mode to conserve the battery. I am guessing that a low batter is the problem, but when I take it to the Ford dealership they don’5 know what the problem could be and they pump off. I am driving to Florida soon and I don’t what the car to die on the way due to a dead battery. Any idea how I can address this? Quote Link to comment Share on other sites More sharing options...
Will2U Posted September 11, 2023 Report Share Posted September 11, 2023 It is my understanding that many of the deep sleep messages were programming errors and you weren't actually going into deep sleep mode. I got the messages, too, but the car functioned fine. I read something about this recently but I don't recall where. Auto start / stop is very complex. There are posts in this forum that list the criteria. During the summer, mine seldom kicks in. But that's okay. If auto start / stop doesn't kick in, it doesn't necessarily indicate a bad battery. If the dealer has tested your battery and it shows good, I wouldn't fret it. Take the trip and enjoy the drive. 2 Quote Link to comment Share on other sites More sharing options...
dabangsta Posted September 11, 2023 Report Share Posted September 11, 2023 There are various SSM and CSPs for 2017-2022 vehicles and deep sleep message when: the battery voltage is above 9.5v SOC is above 50% it hasn't sat for 14 days no TCU update received OTA (all of the above items mean it should not go into deep sleep, and a BMS reset then diagnostics should be ran if the battery tests out) My parents 2020 Explorer suffered through that, and the dealer was oblivious to any of the SSMs for it. I am not clear on if they had issues with auto start/stop or not. Did the dealer actually test the CCA of the battery or possibly just a quick voltage test? Seems early for a battery to have gone flat, but when I let my battery in my 2017 Escape get down to 200 CCA (it was a 760 CCA AGM battery), it wouldn't do auto start/stop (always the grey A with the slash), it would go into deep sleep overnight, and I couldn't listen the radio in accessory mode (which the equivalent to that in your 22 Edge might not be the same). 1 Quote Link to comment Share on other sites More sharing options...
George Hyma Posted September 11, 2023 Author Report Share Posted September 11, 2023 Thank you. The dealer didn’t even test the battery. Dealers aren’t helpful. Quote Link to comment Share on other sites More sharing options...
handfiler Posted September 12, 2023 Report Share Posted September 12, 2023 I store the car in the garage for the winter months. I get the deep sleep notification after 2 weeks of non use. Even with a fully charged battery on a maintenance charger. Ford should have based it on battery charge level rather than duration of inactivity.

Buy your own digital tester like the Solar BA7 or have it tested at autozone, etc. Make sure they test CCAs. Quote Link to comment Share on other sites More sharing options...
George Hyma Posted September 12, 2023 Author Report Share Posted September 12, 2023 I tried Autozone this am. They tested it and said the battery is fine. Thanks Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 14, 2023 Report Share Posted September 14, 2023 do you have the numbers from their test? these are the same guys who say capacity has to drop more than 25% to qualify as weak or not good. sometimes 50%!

enigma-2 Posted September 17, 2023 Report Share Posted September 17, 2023 I agree with @akirby, buy yourself a Solar BA9 (this unit tests both battery CCAs & charging system). $58. Cheap insurance for piece of mind. Can't tell you how useful it's been for me.
