ACCM update SSM53801 did not work in my case for Deep Sleep

[ZABSMAV]

Russian made software or corporate computer ....
Ya I'm hoping those computer system are a tad more secure than allowing personally loaded programs.

Since not a default setting, it should not be available in their software package which does many similar things.

Also - the timeout really only matters if you have something plugged into the outlet using power. Perhaps you do.
But a powered outlet (think your house) doesn't mean there is power used. If you have a USB adapter in there showing V, then that much power is being used until the timeout.

Deep Sleep isn't a gremlin - it's an attempt to preserve battery life because the system has no idea how long the truck is going to remain unstarted.
That's merely an indication the battery has reached a problem state requiring it (unless 14 days non-started was reason).
But you'd hopefully notice lights going off sooner & sooner before that stage is reached.
And some systems report thru Fordpass that Battery Saver has been enabled before Deep Sleep. I'm guessing Lariat because my XLT never has.

Deep sleep is definitely a "gremlin" as you call it (a problem). A vehicle should be fine sitting for a week. Or two or six months. I've gone out to a car (not a Maverick , obviously) that hasn't moved in six months and it starts right up. There shouldn't be significant enough draining of the battery when the Maverick is turned off to drop it into such a critical level of discharge. There is definitely something wrong in the design of the Maverick and Ford needs to get with the program and fix it.

I mean the Deep Sleep as a process and failsafe.
Compared to some Onstar nightmares where it kept attempting to reach out and drained the battery, perhaps not overnight but each day of non-use - I think it is a feature to disable the modem if things are looking bad or because unknown how long the truck will sit.
(did that car that started up after 6 months non-use have remote unlock?)

And that failsafe hopefully allows the going out to start it right up after a week, or 2-6 months.
Of course the alarm systems and remote unlock systems would still probably cause enough of a drain eventually, unless Battery Saver eventually disables them too.
Around 25 mA drain expected will eventually lower a battery enough.

I view it the same as the ability to auto-shut off an overhead light, because driver left it on accidentally or someone didn't shut a door completely and notice it.
That started being included in cars at some point - and I'm glad, saved me a few times.

The fact that the "feature" must happen so frequently because of bad charging scheme and low SOC of battery, and worse on some trucks than others - totally different thing.

The NHTSA just doesn't seem to view low battery issues as a safety problem that forces investigation and changes and recalls. It seems if you can't start the vehicle - you aren't a safety issue out on the road.
(unless your bad battery fails to let the AS/S work correctly, or the BMS allows the AS/S to work on a poor battery when it shouldn't - then a recall - but that ain't the hybrid).

Except the vast majority of posts about Deep Sleep - the truck does start.

Some eventually don't. And they can't get out on the road then.

More often those posts say the battery is finally tested and found bad enough to be warranty replaced.
They never reached a no start situation.

I've looked thru recalls for other brands about battery issues - I maybe saw one that was about a starting issue, others are about problems already being on the road and the battery has an issue, like the Maverick EB, shorts internally, or bad harness connections allowing a quick rub-thru shortout, ect. Or an actual short because of shields being inadequate.

This issue needs to be properly passed on by dealer techs or it's never going to look as bad as it is.
Thinking of the work orders that have been shown in threads - "tested battery - good, owner told to drive more". Just adds emphasis to Fords thought there may not be a problem.
Now a few posts shared the test was 42% or whatever, others have shown 39% seems to be the cutoff for warranty battery.
Why can't all the good tests show the still rotten SOC level it's likely at?
I'm wondering if morning battery levels is a stat that is uploaded to Ford to track.
While many of us don't have a current issue - there's no way the values are good anyway.

If you can convince NHTSA it's a safety issue, I'll think you'll have tons of instant submissions.
But if they all say Deep Sleep I couldn't start remotely - you ain't getting anywhere I fear.

It's rediculous that we have a brand new vehicle on it's third battery and it charges to 50% SOC.

(2023 Lariats do not have remote start on the FOB- they switched to the Ford Pass app).

They must have brought it back for '24, mine has it on the fob. [Lock],[2x],[2x] (The button right above the overly sensitive panic button)

Yep and it's never going to be really fixed until ford's software engineers correct the software coding. Been going on since MY22, starting to show itself in MY25's. Dear Ford, it's the year 2025, no one should be forced to buy their own battery maintainers, jump packs, etc. to keep their batteries charged properly or jump start them on a brand new vehicle you built, especially since you've had complaints since MY22. Just my opinion/2 cents on the matter. Thankful I haven't had to deal with the issue

Just putting a $135 AGM battery in there seems to fix 90% of this issue. Reports are you might still have a very occasional deep sleep. That's probably fine for most owners.

In addition: I also changed SOC setting in Forscan from 80 to 100%.

My Hybrid hasn't reported deep sleep in over a year.

Cheers!

Did the same thing. No problem for over a year.

I totally agree! This all seems like a class action lawsuit. Does anyone know a good attorney?

@EffNo50

About that panic button on the fob:

Ignore this post if you knew this already, but Forscan allows you to change the functionality:

- Require a double press of the panic button. (which is what I set mine to => No more accidental honking ).

- turn off the horn (so panic mode only flashes the lights)

- disable panic mode altogether.

Cheers!

That's what I understand. They took the remote start off of the fob in 2023 Lariats, believing people would use the FordPass app. Then they realized people were losing that availability when their vehicle kept going into the deep sleep problem.
