WSR, is it possible you could share the work order or the dealer that performed the above mentioned TSB. I just had the flywheel damper replacement done due to the "marbles in the motor" issue and they also replaced the battery due to the dreaded deep sleep issue. The service manager drove the car to make sure it was fine before he called me to pick it up. FordPass showed the car had changed locations so I knew it was moving around. It didn't even sit for 10 minutes and it was back into Deep Sleep mode. Thought maybe if I could show the TSB you mentioned was performed on a HEV and it took care of the issue ... unless the issue came back?
2020 Escape Titanium Hybrid - Deep Sleep Mode
201 - 220 of 238 Posts
It was AutoNation Ford in Sanford Florida.
The service adviser said he would email me the invoice, but I never got it. Since I didn't have to pay for the service, I haven't worried about not getting it.
I have had it go into deep-sleep mode once since the service, but that was 2 weeks ago. I think I had left the headlights on by accident for a little while. So that is what probably triggered it.
Sorry I don't have the work order.
Good luck.
A few weeks ago we got a 2022 Escape PHEV. The other morning it would not start. It looked like the 12V battery died. Looking around the web I found out how to jump start it. The jump start battery showed the voltage way down. We found the high voltage battery was charged over 2/3. In the forums it looks like it is a common problem. Why???
How is the 12V battery charged? It is my wife’s and she has been trying it on EV only and charging it at night. If it is only off the engine or is somewhere in the drive train? If only off the engine it has not been charged for days. Also, she could have left something on. Still, it looks like there is no connection between the 2 batteries.
Note, the previous version of the thread did not give any answers but lots similar experiences. I have ask 3 specific questions.

I merged your thread with the other thread. Better to keep it in one place. So there are not multiple threads when members are searching for this issue
I have read all 206 posts and haven't seen a reasonable solution. My 2020 Escape Titanium Hybrid falls into deep sleep mode every time it is parked more than a few days (or overnight when below -10° F outside). This seems like a significant design flaw given that it requires a jump start to deactivate deep sleep mode. A higher capacity battery simply delays the deep sleep mode activation and isn't a useful solution. Maybe I missed it: Has anyone found a solution that doesn't involve a jump start?
EDIT: For the time being, I've connected a Battery Tender® to maintain the charge on the battery when I know I won't be driving soon. This only works with an AC outlet, not typically available when traveling overnight.

IN SUMMARY:
From this thread and other places I have been reading “Deep Sleep” is a recoverable mode. There are multiple ways to get into this mode. It turns off a lot of things and does not discharge the 12V battery as fast. There is a little dance you can do to get it started.
When the 12V battery dies the car often goes into Deep Sleep first. Not always but often. This is why some get this message on the cell phone app before total discharge. Again, often but not always. The only way to recover is to jump start it.
The excessive vampire 12V battery discharge has been going on for years in the Ford regular hybrid and PHEV. The PHEV is worse. When Ford went to a smaller battery things really got worse. Having more blood to suck the vampire does not kill the battery as often. Some are able to completely avoid it. Others are not as lucky but at least it is not nearly as often. Upgrading the small battery helps. Some software upgrades satisfy the vampire better. Again, some are able to complete avoid it but others are not. Some software upgrades make it worse.
Ford is never going to fix this. I expect someday there will be a class action lawsuit on the issue.
For now the only solution is to carry around a jump starter. These currently come in 2 main versions. Lead acid battery types are larger, heavier, and cheaper. Lithium battery types are smaller, lighter, and more expensive. Another type are supper cap’s but these are rare and expensive. All lose power with lower temperatures. Lithium batteries are worse but some come with built in heaters. To me space and weight are a premium. I am going to get a lithium jump starter and suffer.

I thought switching the battery to an AGM battery fixes this issue for some of the members in this thread?
It does....I am surprised Michael did not see this in his research here.
Switching to a larger battery delays but cannot eliminate this problem. If you use your car often enough, the larger battery may make this problem occur far less often. Kind of like putting lipstick on a pig, still not attractive except to another pig.
When the car is in Ready mode, there is a DC-DC converter that steps down the High voltage to keep the 12V battery charged and run the car's 12V stuff. So when you're wife was driving in EV mode, it was keeping the 12V battery charged. However that's only when in ready mode. So even when you have it plugged in to charge the high voltage battery, it's not charging the 12V battery.
There is a known bug where the 12V battery gets drained while charging the high voltage battery. My guess is some module wakes up while it's charging that drains the 12V. Dealer needs to program an update on a few modules to correct it. Another I've heard is the ABS module not going to sleep, and draining the battery faster than normal. Thankfully I've haven't had any issues with my '22, and I've had it sitting for a 3-5 days without issue.
I have read similar statements in other forums. This is what I said in my summary but without the illustrative language.
Well that is certainly not the case with many posters here who have fitted the larger AGM battery to their 2020 Escape Hybrids if you do research here. In any case I have read about it solves the deep sleep and other battery issues.
2020 Ford Escape Hybrid - replace 12 volt battery with...
Here's a quick how to video that I made showing replacing the stock 12v 45AH lead acid battery with a 12v 70AH AGM battery. Some folks have had issues with the stock 12v battery running down and not being able to unlock the vehicle, or start it by remote, or some to even start it at all, as it...

Someone somewhere posted you could kill the 12V battery with the emergency brake set. I have not tested this. Still points to one of the vampires in the braking system software. I think there is a whole hoard of vampires lurking in other places. Kind of a whack-a-mole deal.
I appreciate your comments.
I should have been more clear for other readers: The AGM battery will significantly reduce the chances of the car entering Deep Sleep Mode but it won't entirely eliminate the chance of it happening.
The AGM battery voltage will be depleted slower than the OEM Ford battery. If the car is driven often enough, the AGM battery will prevent entry into Deep Sleep Mode in most cases.
The AGM battery will be depleted (and the car will enter DSM) if the car is parked too long, the temperature is too hot or too cold, and when the AGM battery gets older.
This is well stated but I like your pig analogy better. I really hope that wiz043 reads it carefully. To use my analogy, a bigger battery does not kill the vampires but is able to satiate them before they kill the host. As often.
I do have a question about your last sentence. When the battery is fully depleted let's call this XDSM for eXtra Deep Sleep Mode. From reading a lot about the problem in this forum and other places I think it is possible to go into XDSM without going into DSM first. This is really hard to ascertain and is more hinted at than stated. Does not matter much on how you get to XDSM. What matters is how to recover.
To the vampires: Bon Appétit.
I have read many forums on this subject here and elsewhere and done other research and followed videos etc. 'carefully' and in just about every case the fitting of the larger AGM battery solves the deep sleep and other issues concerning the battery especially in cases where the battery is depleted overnight or upon restart after driving during the day. I am not making this up.
Of course if the car is not driven much the battery can lose charge but that applies to any battery in a vehicle whether it is petrol, diesel or hybrid.
During the worst of Covid prior to vaccination when we were limited in our activities I rarely used my Escape and often had the battery attached to a trickle charger to keep it completely charged otherwise I would lose the stop/start feature.
I didn't use that 'feature' much anyway but if it failed it was an indicator that the battery had lost a little of it's charge.
Posters here with this issue have probably seen this but Ford claim the car can go into deep sleep mode if sitting idle for 14 days or more but it appears from posts here that it can happen well within that time with the OEM battery.
Ford claims there is a software fix or a further fix is coming but to date it has worked for some and not others as mentioned earlier
For the trickle charger which one did you use? Did you connect it under the hood or in the wheel well?
In the wheel well???
Of course it was connected with clamps to the positive terminal and negative ground position on the battery under the hood.
