I put a solar charger that seems to help with the battery drain.

I like the Solar Charge idea. If I have it putting the charge back thru the cigarette lighter, will the current flow stop, to the battery, if the car is turn off and the cigarette lighter auto disengages? Does this mean you have to wire to battery?
My ecoboost gets the deep sleep message sometimes , use a trickle charger to top up the battery. No more messages.
Mine is in deep sleep every day.... Thought I solved it after turning wifi and all the connectivity features off after doing the radio software update. It took about an hour. What must have happened is it charged the 12v during that time as my Mav was good for a week after that and then deep sleep started again... Today I drove 20 miles and as soon as I got home it went back into deep sleep (dash and interior lights don't come on when opening the door)... When are we going to see a fix for this issue?

"Deep Sleep"
Is build date critical with this problem?
Could this be related to the Battery Harness Issue?
That date was around 3/10/22.
My Hybrid was 3/10/22.
This Truck is still a keeper.

This will not get fixed until Ford recognizes it as a problem and assigns the proper resources. I have the same problem with my Lariat Hybrid built 3/8/22. I have had it looked at by two Ford dealers and have an open case with Ford Customer Care case. I now have to charge the battery using a trickle charger then reset the BCM. It doesn't fix the problem, just prolongs the deep sleep.
Same here. I asked my local dealer service rep about it and got a bunch of Fordspeak about how the Maverick uses sophisticated electronics that require power, yada, yada, do. No kidding. They want us to believe the Maverick is the first? They're not addressing the problem. More of us need to complain either to dealers or directly to Ford.

Oh, You got "Deep Sleep". But in it's early stages the truck still starts. This is the stage my truck is in for about 5 months. Trying to guess what the next step is:
Transmission
Battery
Battery Cable
Problems.
But I do love my Truck. It's perfect, except.

Charging the battery overnight then resetting the BCM fixed mine for 1.5 months. I just got a deep sleep message last night but I think it's due to adding a enclosed powered subwoofer which has been turning on randomly as I wired it into the speaker line input. Even opening and closing the doors causes it to trigger. I'm changing that to a remote wire from the ACC today.
