Make sure you have a jumper battery with you at all times. A digital volt meter is handy as well to test your battery to makes sure it is above 12 volts after an occurrence
Well I must be missing something? I‘ve had my MAV since 12-21. What is deep sleep? my MAV is a 2022. I refer to it as a plain jane.
I have a first edition march 2022 hybrid. Several occasions of no dime lights. I do not use Ford Pass and have not noticed my phone connecting though I believe it was set up but would not bet on it. The wife's phone is set up and connects. I have never asked and she has not mentioned deep sleeping. I have PowerPoint voltage monitor In dash which I pull partially out before turning truck off to keep the led on it from keeping that circuit active for the programmed delay off. I did notice on my monitor after at 20 months or so and 22k miles when the reprogramming recalls 23E07 & 23E09 were applied that the running voltage went from 14.8v-15.2v to 15.1v-15.5v (15.6v sometimes but dropping to 15.5v in a short time) and stayed in that range for much longer time period. I have no idea if those updates directly addressed the deep sleep trigger points. When the Traveling Tech performed the updates in my drive while he was watching his laptop he commented "Those updates are changing lots of modules and sometimes the same ones". FWIW. If you have not had them done consider doing that. I also double lock my truck most nights as that turns off some of convenience lighting plus ? sooner. I did not put my noco genius 5 on my truck until after 20k miles as I wanted to see if battery would die. I am at 24.5k miles and currently have noco on truck (today is 4th continuous day and is in maintenance mode. Yesterday I caught it in optimizing slow blink which with the continuous draw on battery is not surprising. Going to need truck tomorrow so will disconnect noco and lock truck so the up to 6-8 hour battery learn procedure can happen (some of mid night clicking ?). Hopefully with the topped off optimized battery the BCM & BMS will have all their parameters learned. I intend to do this every 3-5 months no matter which brand or type of battery I have. Maybe I can get 6-8 years out of my 12v, only time will tell. Good luck on yours.
I agree 1000%!!! Ford thinks this is a feature but when you hit 50% discharge level, your battery starts to degrade. This so called feature shortens the life the battery. It use to be the average life of a battery was 5 years...now it is 3 years and batteries are more expensive too!
It's the dumbest feature I have ever seen. Lowers your confidence 110% .
Some electronic controlled battery chargers or battery tenders need to see a certain voltage before they will charge. I can't remember that voltage, but if you are too low it may not be charging at all. I keep an old style shop wheeled charger that simply shoots voltage out regardless of the condition of the battery. If you can borrow an older charger like one of those, give it a try.I got my first deep sleep notification in the Ford Pass app last night, Because of all the threads about the issue I wasn't too concerned. However this morning I went out to run an errand and the battery is completely dead! No lights or any activity getting into the truck!
I connected an automatic battery charger, it comes on and shows the battery capacity at zero and the voltage at 4 volts. I left it on for a few hours and come back later to find it says battery failure!
Called Dealer and they called me back and will have mobile service come check it out tomorrow morning. It will be interesting to see what they say..
Here is a little more info on how to get a very dead battery back to life. Maybe.
