Deep Sleep Fix Not Released

[Master Blaster]

In FMC defense the key word is almost every Hybrid is experiencing, my 2023 XLT Hybrid has not had a single issue with batteries. I hope I’m not putting a spell on my Maverick with this post.

My 23 Hybrid has now had 3 batteries in only 22k, so you're just incredibly lucky.

FROM FORD:

Special Service Message (SSM) #53087 for some 2022-2024 Ford Maverick vehicles with the 2.5L full hybrid powertrain addresses an intermittent 12V battery drain when the ignition is off. This can lead to battery failure, particularly in vehicles parked for extended periods.

Ford recommends that dealerships perform steps like a 12V power reset, fully charging the battery, and checking if the battery needs replacement. If a replacement is necessary, the new battery should be fully charged and a Battery Monitor Sensor (BMS) reset performed.

Ford Engineering is developing a software solution, anticipated in the first quarter of 2025, and dealers are advised to monitor OASIS for updates

Exactly.

That is for the intermittent battery drain. Always was.
May kill the battery. Reset computers to turn off whatever was the cause. Charge it. Check it. Confirm not dead this time.
And they think they found the issue in the ACCM.
Software updated.

I'm not sure about your issue leading to deep sleep mode - but mine ain't intermittent by a long shot.
Every single drive (except for maybe 2 long trips).
Neither do the vast majority of posts about deep sleep indicate a battery drain that prevents them from starting.

This is what I mean by rumor and myth.
That SSM has nothing to do with the bad charging strategy used by the BCM system.

That is the issue the vast majority of posters with deep sleep mode have.

And if everyone keeps presenting the issue as the wrong thing - well, we are getting exactly the results of when that is done.

It appears that the SSM was their answer. And they delivered that. Did it fix the problem? Appears the answer is no. So now waiting for a new "final answer".

It looks like their "answer" is keep rolling defective products off the line in Mexico in record numbers and ignore the problems people have been, and are still, having. They should own up to this problem and also accept responsibility for those who had the AC Module update that bricked their AC. That should be paid for and remedied by Ford as their defective software update killed it.

You are likely correct. Most people just jump in their vehicle and don't pay any attention that their interior lights weren't on. And I'll bet that most people don't know that their Ford Pass lost connection because one has to go into their cell phone settings and specifically turn on notifications for the Ford Pass app. If they didn't take that step, they'd never know the multiple times that deep sleep problem occurs.

I got a notice from my app 2 weeks ago about low tire pressure, within probably 20 sec of the screen pop-up while I'm driving. So setting is correct.

I've never gotten an app notice that Deep Sleep mode has been enabled.
Battery over 16 months old since truck taken out of transport mode.
48th week of 2023 date stamped - so 4 months sitting in truck.
Hangs out below 12V area, except for right after a drive, but not accurate then.
Manages 50% SOC or barely above (few dips below) according to BCM estimate, except for longer drives may get up to 60% by the end (but that's not accurate then), every blue moon near 65% (which month is blue?).

Now - Battery Saver features on the other hand - that started last fall and of course winter made it worse.
Power port turns off the instant the door opens, light stays on maybe 5 sec after the door opens if left open. Don't have keyless entry for those things to disappear, so lights is it for my trim.
If 12V at end of trip reads a tad higher on power port V reading, lights on just a tad longer.


Here's another potential problem at dealership I've seen 2 posts comment on, didn't think much about it until now, because at time I thought of course they can.
Dealership can read the notifications that Fordpass would have sent on to the app, and that includes the Deep Sleep mode notices.
If someone complains to dealeship about deep sleep when it's really the battery saver items - which may not get a Fordpass notice anyway (mine don't), I'm just wondering what they think when they see that no, you haven't gotten that notice.
Do they disregard deeper testing and just do simple test on battery?

If I went in complaining strongly about deep sleep mode - they'd see I didn't know what I was talking about since an alert was never sent.
Would I be ignored - told to drive it longer? Would they spend tech time on non-warranty issue testing the battery, or just a simple voltage reading? Would I be told to get a charger?
Or totally at their expense unless proved to be under warranty - would they give me a loaner vehicle, charge up my battery and let it sit overnight, and then give it a full load test the next day? Probably another blue moon required for that outcome.

That's the problem with the forum stats on it.

There were never that many posts about an intermittent parasitic drain that ended with dead battery the next morning unable to start truck.

So it'll be awfully impossible to tell if they fixed that.
I know of the 3 posts I saw about actual troubleshooting being done on what the SSM was addressing before they had solution - 2 of them ended in the draw being from the TCU that was then replaced. Never saw ACCM being the end root cause.
3rd post I saw, much more recently, did share the fan kept running after they got out and returned to truck later. That poster started turning the AC off before turning truck off. Never went in to shop for it.

Considering the 3+ days of tech time to troubleshoot the draw described in the posts - I can see why they wanted to cut that process down or out for warranty work Ford ended up paying for.

So was the ACCM the only answer for that SSM - maybe.

Was the ACCM the fix for the problem that Ford never made public comment on - no.

With the 12v batteries in Maverick hybrids hovering around 50% state of charge it says all one needs to know that there is a serious problem going on.

A 12v battery in a vehicle should be rapidly and properly recharged to as close to 100% as possible. With a battery chronically undercharged at around 50% SOC, it is not a question of if it will become sulfated, it is a only a question of when it will.

It doesn’t surprise me with the number of batteries you’ve had I keep waiting for the other shoe to drop so to speak after I read the posts here I hope FMC gets their act together soon before my shoes fall off. Other than that we love the Maverick.

Don't get me wrong, we love our 2023 Maverick Lariat Hybrid with the Lux package. It is a great, very fuel efficient vehicle with a lot of creature comfors, but Ford has an obligation to fix this charging problem which so many are having and a problem that they have publicly acknowledged exists.

I disagree with that last bit, and the effects of it.

I have never seen where they acknowledge a charging problem, such that there is any fix on it's way.

If owners are led to believe Ford knows about this specific problem - and worse they are working on a solution - what will they do?

Nothing. Wait. Complain (to the wrong ears).

If everyone with Deep Sleep mode or likely Battery Saver functions kicking in - all went to their dealer complaining about it, that the battery is being charged too low to support normal operation, and needs to be checked with tech time on serious load tester under warranty so Ford is charged - NOW you have some feedback going back to Ford.

Owners driving once a week or two need not apply for the mission though - won't help the cause.


Filling out NHTSA form hoping for recall isn't going to work - it's not considered a safety issue by the powers that be, because if you can't start it to drive you aren't a hazard on the road.
Argue that all you like - just isn't the case like it or not.

Calling Ford without a shop visit isn't going to go anywhere probably, they'll log a complaint, look at last data upload from truck, and see the values are where Ford has said it's acceptable.

Forget the engine tuning on hybrid thread - let's get those tuners into the code for the BCM!

 

[boxster03]

you have to ask yourself - is it ok for a new vehicle you drive 5 miles a day to constantly go into "deep-sleep mode" disabling half of the functions - obviously not (not to mention the half-dozen recalls)

 

[Samcat13]

AS long as I can get in my Maverick and it starts and gets me to where I want to go I don't care about anything else. If it wants to go to sleep and rest when I'm not using it its OK with me. Some people like to complain and that is OK with me also. You can complain all you want but it won't get fixed until Ford is ready to fix it. If I was that upset with Ford I would sell my Ford vehicles and stock and buy something else.

When someone buys a vehicle advertised by Ford as the top of the line model, with all options, and they even call it the Lux package, the buyer has a right to expect that ALL options work as advertised. We were sold the fact that in order to remote start or monitor our vehicle remotely we would need to use the FordPass app. When the vehicle repeatedly suffers the deep sleep problem it removes a number of important features that we have an expectation that they will function. I don't "like to complain" and don't believe it is called "complaining" for "calling out Ford for telling us it is was/is a known problem to them and Ford told all of us it would be solved by March 31st, and then changed that to June 30th, and yet they still have not announced the fix to prevent the vehicle from going into deep sleep. Glad you don't care that you lose all communication with the vehicle including location info and status, and don't care if you or a loved one has to enter a totally dark vehicle at night. I do care, and have been calling the dealer and Ford every two weeks asking them when this will be fixed.

No, it is not acceptable. Seems Ford is more interested in pumping out Mavericks from their plant in Mehico (should build it here in America) in record numbers, than fixing problems in current owner's vehicles.

 

[HenryFord]

I completely sympathize with the OP's comments. It is very frustrating when you feel there is a problem and it isn't being addressed. However as others have noted I don't know that Ford has even officially acknowledged there is a problem with the 12v system which is a problem in and of itself. We know they monitor these forum and they have a fantastic social media team and some great people that work for them. I have been impressed with most of the interactions I have seen. I am curious if anyone had put the team in the loop and tried to get some answers about this concern over the 12v system. I mean they have to know they just replaced a bunch of batteries already and switched manufacturers. That does not seem to have addressed the issue. So maybe we need to use a different tactic to get their attention.

I know my work around right out of the gate is going to be pull F11 fuse, and put it on a battery tender between drives until I see an all clear here on MTC. There has to be a way to escalate with Ford to see what they have to say. If they are working the issue then just say that, but something is better than nothing.
