Had just about enough of battery saver and deep sleep

[MakinDoForNow]

I’ve charged my battery to 100% multiple times and followed this. Still get deep sleep. My biggest peeve with my hybrid.

Next time it 100% try the new battery/maybe when charged up to 8 hour with truck locked learn procedure. This could possibly reset some charge parameters the BMS uses.
ALSO: After I had TSB 23E07 and TSB 23E09 done on my lariat my dash power point voltage monitor shows 15-15.6 on it much more so it appears that they changed something and possibly there could be more available for the BMS. So if you haven't had them done that possibly could help. For the half second before the dcdc powers up the monitor shows the 12v soc but it probably reads low since things are powering up. I have never experienced deep sleep but have had no dome light on several times. I also double lock my truck most nights as that turns the dash and courtesy delay lights off (plus who knows what else) earlier. I doubt if it's enough to matter much but WHY NOT?
Good luck!!!

When I deleted Ford Pass from phone, the truck stopped the "Deep Sleep crap" the battery is happy and there's no issues with not starting. You can call me crazy, you can call me archaic but my Maverick is a happy camper, now.

Truck goes 2 days without driving into battery saver and less than a week for deep sleep, all updates done dealer bench tested battery twice and it has passed.
Fist 6 months it took 2 weeks to go to deep sleep ( sometime I travel on business and drive other vehicle)
Not sure if this is what you guys are seeing but it's super annoying

My 14 year old ram sits for weeks since I bought our maverick without being started and starts right up even with single digit temps in Michigan. My maverick is an ecoboost and has only sat 3-4 days max without starting,but starts right up.i think Ford dropped the ball with the hybrid in cold climates!

I have 2022 first edition lariat almost 25k miles 22 months. Never had deep sleep but have had no dome lights on occasion maybe 4 times. After TSB 23E07 and 23E09 at about 22.5k miles truck seems to charge and run better 1-2 mpg better (maybe?). Also had TSB for engine fire holes in air dam and removal of two of radiator air slats. Have not had the yet undetermined solution for engine fire done. Did also have the positive overlay cable TSB performed. Also had the side curtain air bag replacement done which resulted in the exposed edge of headliner. Dealer has one on order and has been great with service some of which has been remote in my driveway and some with pickup my truck at home and return it after service call or TSB. Just had truck sit 4 nights 2 less than 15°F and it started right up. Note: startup was in am temp at 21°F PowerPoint monitor showed 12v bus at 15.5 volts heating everything including wheel and drivers seat. Only placed maintainer on battery once at about 20 months for six days (should have done so sooner but never did). I will use a maintainer about every three months going forward.

It's still in battery saver mode because the majority if not all the 600mah is going to support the phantom draw. I suggest at least a 2amp maintainer. I have a noco genius 5 which can take 3-4 days depending on soc. It drops into stand by mode since it adjusts for ambient temp so it may top it off if temp changes plus it reactivates charging every day or two to top off that used by the over night discharging.

If this is the case with my new maverick I won't keep it. I need a reliable truck.

I have now started having the interior lights not going on. Also the ford pass app not working deep sleep mode. Winter has finally hit in Buffalo NY. Not doing much driving plus when I do at most maybe 15 miles. It seems the people not having any issues are in warmer areas.

I have a voltage readout on cigarette connection as its also a on off switch were i connect my dash cam. So I can read both output when running about 15.2 volts and battery voltage which last I looked I THINK as I didn't record it was maybe 12.3 volts. . I will state taking picture of that readout and keep a record on it. I hate not having a dome light.That sucks.

I just drove this morning open car door after sitting two days had dome light. I drove about 4 miles one way went inside 5 minutes back in no dome light WTF. Drove back home shut off no dome light.

So far one poster put die hard battery in about 210 bucks!! and seems to have fixed his issue SO FAR. BUT is it permanent fix ? If I new it was I might bight the bullet and pay the money.

I carry a noco jump box just in case. I have had my hybrid only since mid august . No issue till now, Even when it sat in September for almost 2 weeks. .BUT drive a lot more and farther summer time.

It is my opinion that the Fordpass is the problem. Took it to the dealer. As soon as they saw my aftermarket amplifier hook up, they blamed me. Dealers NEVER listen to the owners. I even printed out in detail things to check that may be causing the issue. Nope, they said. My amplifier is the issue. "have a nice day". It isn't my amplifier. Doesn't draw nothing as I have an "off switch" to disconnect it when I leave vehicle. Ford, please, own this issue and get it done right!! I did buy the Die Hard battery prior to my visit to the dealer and they blamed me for doing that!! Funny thing, battery and sleep mode issues have mysteriously dissappeared since I visited them. I hope it stays this way.

Ford shoukd:ve put an AGM Battery instead of a crappy EFB.

Hey Ford... battery saver and deep sleep are one of the most annoying features even on 2022 initial models. Whilst the idea is excellent, it's tendency to kick in soooo frick'in early makes the Ford app and remote start, unlock etc all TOTALLY useless. Buyers beware.

Experienced this for the first time, this week. Mav 2022. Our temperatures have hovered in the teens and twenties for the past week. Hadn't driven for about 4 days.
Experienced a similar cold stretch a year ago but no problems then. I have several recalls pending and will "consult" with the Ford service manager when I take it in.

Here here! Ford? We know you're on here.

This shouldn't be the case, my wifes mazda 3 and my Ram can go weeks and still maintain over a 12v. Mines goes 1 or 2 days and drops to 11.7, 3rd day 11.63 and triggers battery saver

I think your problem has more to do with the battery management system not reset correctly. I don't think it should trigger the battery saver mode until voltage drops below 10 volts. It sounds like the system thinks you're starting at a lower voltage than you are. I'm pretty sure I read that it needed to drop below 10 volts.

Confidence....none
Preparedness....fully
Thanks guys

If the op would pull fuse 11, I'm betting the issue would go away. I feel like data being sent/received is the biggest drain on these trucks. I've not had any issues over 22k miles, but I pretty much drive all the time. I don't use the Ford pass app, and I put my keys down when I walk in the door. I figure pulling that fuse will help with the drain, and make those paranoid folks among us feel better too. Win win! I know, some like the app and use it often. In that case, Ford needs to install better batteries and make sure the truck charges them. Either way, its bonkers that people can't depend on their new vehicles. Get it together Ford!

...Yes the original Hybrid Escape was bulletproof. Fewer bells and whistles. But solid....

True. And it also cost a lot more back then than the base Maverick costs now.

10 volts and i can guarantee it wont get a ready on dash for sure at 10 volts. Mine still showing over 12 volts and no dome lights.

Now today my cigarette lighter unless car is running shows no voltage so I cant even read battery voltage like after i shut Mav off cigarette lighter would stay powered until I open the door. Now it goes immediately off. . So I assume mine is getting even worse. Been much colder here now. Today up to 26 F though.
