Maverick hybrid has the same issue as other Fords
Sponsored
Alternator isn't the problem at least from what I found. The battery management system only allows a certain about of AMPs to come from the alternator to charge the battery. Likely due to fuel savings. The battery is only suppose to charge up to 80%, but, the State of Charge can drop 10% easily overnight.I have an Ecoboost that wants to do the same thing if it sits for more than one day. I have a second one that has only done that once and It’s a year old.
The last time it did that about 2minutes after a 40 mi trip. I’m thinking it may have a weak or failing alternator.
I’m now putting a trickle charger on it every evening to see if that stops it from happening. After that I’ll have the alternator checked out.
Who knows?
My best guess the BMS thinks your battery has a low SoC or voltage and was that way before the trip. Reset might help after charging the battery.My question is still why would it go into deep sleep within 2 minutes of parking it after a 40 mi Hwy trip?
With your Hybrid, have you called your Ford dealership about the issue.![]()
Drove over 200 miles and still get this message. I can schedule a start. I vannot remote start with the app or the fob.
Good morning! If you can send over a private message with your VIN and dealership info, I'd be happy to look into things on my end.![]()

How did you get this to display on (I assume) your cell?Example of a 5 min drive. However, I did have the vehicle on the trickle charger in the afternoon (shows full) and went for 5 short trips around the city, this is roughly 24h later. My NOCO G7200 was attached to the battery and after the BMS sensor. Could be failing and thinks the battery is full, need to check.
Note the SoC is at 60%, it was 59% when I first started the truck.
Tested the battery at 700CCA (not sure if it's correct), aftermarket batteries are 760CCA. Tester showed 625CCA and to recharge the battery.
I asked if remote features disabled is common and they said it's due to the cold weather. We've had a few patches of -39C/-38.2F to now - 19C/-2.2F. While it's understandable, I laughed and asked if charging the battery to 80% is normal too, which was yes.
They also added you're lucky you don't have a Mach-E as if the 12V battery dies your shit out of luck shifting out of park. Dealers solution is owners need to carry a jump/booster pack.

Forscan Lite and a OBD dongle, works well on Ford's.How did you get this to display on (I assume) your cell?
I had the same messages about 'deep sleep' and the Auto-SS not working within a day of a 500 mile highway trip. There is something amiss in the BMS strategy/logic/software/hardware.
The OEM battery was rated at 900CCA and tested find and the Auto-SS was still disabled last spring.
