'22 Hybrid - still deep sleepin'?

[avane]

[Disclaimer: I've been experiencing deep sleeps for my truck on and off since I got it in '22. I've had the battery changed out once, the TCU reprogrammed, and most recently, the recall for the 12v battery cable overlay installed]

So for the past few months, my truck almost instantly goes into deep sleep mode once I'm done driving. I've had the deep sleep issue correct itself before where a bit of driving remedied it, but now long drives won't even help the battery stay on after I turn off the car. Note that I haven't had any issues with no-starts or anything, it's just the annoyance of having no cabin lights/exterior lights turn on when I go to open the doors, etc.

But of course, there's the fear of the no-start occurring at some point despite having the battery cable overlay installed now. I'm curious if anyone's dealer has fixed this instant deep sleep issue for them (despite doing all the recalls and wiring harness changes) or it's something you just live with (which I refuse to accept is the norm).

Placed it on a charger and it took around 3 hrs to go into float mode not sure that's a good sign or a bad sign.
Battery was resting in the high 11v range. Battery replaced in March or April of this year on my 22 hybrid. Had a few deep sleep cycles since.
Had cables replaced and early software update to limited improvements ( dropped deep cycles in half to one third ) only one since battery replaced the truck needed a jump to start. My jump pack is permanently setup attached to battery and just needs a turn of its switch.

ce.

I mean the fact that you have to charge it is a bit annoying isn't it with such a new vehicle. Did you do any other fixes yourself or with the dealer?

It's a problem that plagues a lot of FORD vehicles currently, unfortunately. Even non hybrid ones.

I feel your pain. Too much crap causing vampire drain after the vehicle is turned off.

Off means off, FORD.

I had a 22 Escape Hybrid I never planned on keeping, but this was one of the major issues that I got rid of it earlier for. I know that's not a solution. Sorry. But for my EB, I just don't use the Ford Pass app at all. Just another thing for the AI to communicate behind my back lol, as tin foil hat as it sounds.

I changed my 12v with a Duralast gold a few months ago. No Deep Sleep since, but not sure for how long

I've been trying to get the Wiring harness replaced since July 5th. May be time to try a different dealer.

If you do a search on my other recent posts, you will see the research I have been doing over the last month. The gist of the research is:

1) It is hard to get an accurate voltage reading on the battery. If you just lift the seat and test, the reading WILL be wrong (by up to about .3V). If you get in and lock the doors, the voltage will change 3 or 4 times over a 3-4 minute period as things slowly turn off. What you care about is the battery voltage with everything off.
2) If you turn absolutely everything off and lock the doors, the truck will loose about .05V per day sitting in your drive-way. If I don't lock the doors, I loose closer to .1V per day. Before I turned everything off, I was loosing up to .2V in a day (but it normally was only about .1V).
3) The battery management system is programmed to NOT fully charge your 12V battery (I assume Ford does this for some perceived safety reason since lead-acid batteries need to be fully charged for longevity). It will give the battery maximum volts/amps until it gets to about 80%-85% and then trickle charges from there. A 250 mile drive will get you up to about a 90% charge on a 100% good battery.
4) Lead acid batteries don't like being less than 80% charged and will start to sulfate. At 50% charge this sulfation increases rapidly. If left at below 12.1V for any length of time, the longevity of your battery is decreased dramatically. A battery tester (I use a TopDon 101) is a good investment and will give you are pretty good view on the health of your battery.
5) The generaly consensus is that deep sleep occurs when the battery is around 11.8V (roughly 25% capacity left).

I live in the country so just rigged up an outdoor solar charger in front of where I park my truck. If I am not planning to drive for a few days, I just put on the solar trickle charger and it keeps the battery at 100% (12.58V).

What a crappy way to own a new truck

I'm not judging hybrids, but it seems like too much of a hassle to deal with, especially if it's a new vehicle. I'm sure most hybrids my not have issues but just based on what I have read on this forum there seems to be a lot. The MPG is probably great, but it seems the means don't justify the ends having to constantly worry about the battery and things of that nature. I live in Upstate NY where the winters are brutal, so I knew I needed the ECO Boost AWD. I can't imagine on top of that worrying on a cold 10-degree day driving through snow hoping a hybrid wouldn't die on me.

Problems posted on this, or any other internet forum, nearly always make it appear that the number of issues experienced with a vehicle happen much more frequently than they actually do for most owners.

Personally, I will never live where just finding the car involves using a snow shovel!

I'm surprised the hybrids don't come with AGM batteries as those are designed for deep-cycle applications. My EB has an AGM battery and I've yet to see the deep-sleep thing. Only my Explorer is in deep sleep and that is only because it hasn't been started in over a month.

I have owned my Lariat Hybrid since April 22. I think think it has gone into energy saver mode 4 times UNTIL I had the battery cable recall done on August 15th. Since that time it goes into energy saver mode within hours of parking it unlocked in my garage. Yesterday I drove it 15 miles to Ace Hardware. Within 10 minutes of being in the store I got the message on my phone. Our 23 Escape Hybrid has never been in that mode.

You’re probably right.

Have any of you guys tried pulling fuse 11, and seeing if that changed anything on the sleep issues? If I recall, that's the fuse for the telematics of the truck, and I'm curious if the truck is constantly trying to "communicate" with Ford. Pulling the fuse won't hurt anything, other than make the Ford Pass app no longer function. I would pull mine and test, but I haven't had the sleep issue so far(fingers crossed).

I am putting my hybrids 12v on my noco at least every 90 days to top it off and possibly let it run it's acid destratification and de sulphate procedures (be sure to get newer/correct model). The new vehicles of all makes are very hard on long life health of 12v batteries. I believe that the float charge ending at 85(?)% is to allow the internal battery temps low to prevent water from boiling off or breaking down and voltage will be gradually reduced to prevent overcharging. I suspect 12v is under rear seat because room under hood for it would be difficult to find and primarily to help keep battery temp lower. It is possible that the BMS located on neg terminal is overly aggressive in adjusting charge rate for temp or perhaps the hybrid 12v needs more airspace to help cool it down. If so perhaps someone deep sleeping could try driving with rear seat up and possibly with small fan circulating air around 12v??? FYI = I increased 12v life on 4th battery in 2012 Honda crv from about 30 months to over 64 months by putting noco genius 5 on it about every 120 days!

We had the problem with our 2022 Mav hybrid for some time. Went through two defective 12v batteries from Ford and kept having to jump them. We had the cable overlay replaced last month and I bit the bullet and bought a Duragold battery myself and replaced the Motorcraft one. Had to jump it once after the replacement but haven't had to do so since, and it has been at least a month. Even if we don't drive it for a day or two the lights come on when we open the doors, etc. No rhyme or reason as to why it suddenly decided to start acting like a real vehicle should, but I'm not complaining.
