SSM 53087 2022-2024 Maverick - FHEV

[Gary123]

Keyless entry is when your fob moves close to truck, it preps for unlock via handle touch, and preps some other systems for driving. You don't have to press unlock button on fob.
Non-keyless you have to push the fob button to send signal to truck to unlock, and then it preps.
Keypad is that too, unless it's actually the factory option wired in.

In either case - the truck is 24 hrs listening for a fob. Keyless has more antennas as it has to distinguish fob in the cab or outside.
So that's not the problem.

Does the dealer report the battery is good, do they say or the paperwork give a SOH reading?
They care if it drops below it appears 40%.
I'd hope they don't call 50% good, but would rather explain it's not bad enough yet.

If your cell carrier is spotty at home, and usually the 3 carriers share the same towers, ATT could easily be spotty weak signal too.
That runs a phone battery down quicker as it has to increase the signal on it's side to be heard by tower.
So too the truck - it appears to only connect hourly to keep unused connection up, but there's extra power used if weak cell signal.
Not sure what happens if really bad signal and it doesn't always get a response back from Ford's server - is it willing to sit there for 15 min every hour constantly trying to get the connection up, or a response back, before it's successful or gives up?
That's a lot of power use attempting that.

WiFi - you have the in-truck WiFi option being used, where your phone connects to the truck wifi?
If so, the truck then sends all that wifi data out the ATT modem - while truck is running or key to On mode - no big whoop, power is coming from HVB.
If sitting in Accessory mode - no good, especially where there is potentially weak signal.

If you mean the info-center option to have WiFi on for the truck to check for updates - as long as it's close enough to get on the wifi, it's once a day - and there are none.
WiFi uses less power than cellular, so even terrible wifi doesn't use that much power.
Now if it was actually downloading data over bad connection, ok that's bad.
But the non-Lariats have no radio updates. So wasted action might as well disable.

HayBales. Your comments are very insightful, and gives me ideas that I didn't get from the dealer. The cell issues makes sense. Thank You!

Keyless
I am NON-keyless. I have a FOB, but have to press the button. It does not open when I get close.

Battery
I'm not sure about SOH reading. I will have to look into y that.

Cell Signal Quality
Cell reception at the school parking is BAD. It is a recessed area with hills on all sides. My son says his phone barely gets any reception there.
Home is better, but not great. Our phones must be set for WIFI calling to get reliable calls.

WIFI subscription
We do NOT have any monthly subscriptions for the truck to have its own WIFI service, if that is what you were asking, but I sure the phone is communicating for Fordpass.
At home, we park in front of the garage, with strong WIFI signal.

Question
1. Are you thinking I can/should disable cell (modem) communication, and limit the Maverick to getting updates through my home WIFI?

SOH - State Of Health, could have a low State Of Charge (SOC) at time of test, but great SOH.
Or as others have seen that dutifully charge their battery or regular basis - great SOC at time of their test but terrible SOH - battery replaced under warranty.
They should have printed it on work order, since that SSM gives instructions that start with full charge and test.

So an assumption that the 3 major carriers usually share a cell tower, and I've been in many a depression with tower on wrong side of hill and terrible if any signal - that's not helping the truck modem in it's connection attempts.
Truck also attempts to connect whenever you key off and it reports up last known location - not sure how long it keeps that up if connection failing. Just thinking of how long a fax machine used to sit there attempting to connect or resend a page, until manual cancel - ugh, all day.

And yes the truck reports to, or attempts, Ford servers, which if using Fordpass, the app talks to also. Fordpass or not - truck will attempt to report in.
Unless it's in DSM, at least then it's not going to keep an open connection in case you want to remote start it. Hence the Fordpass warning.
Supposedly it disabled the modem to conserve battery, so you can start it next time in person.
But nothing says it may not still be enabling the modem to send info out if it can.
Immediate DSM sounds like it knows the signal is terrible and it's just going to inform you via the app the truck isn't available to remote access. Not even going to bother in case signal drops.

Wifi ONLY provides update to the infotainment center, and it's so ancient there aren't any - no need to have it enabled. It was never going to that thru the cell connection anyway.

And since you know truck has terrible signal, and it appears remote start or status may not be useful anyway, you might want to disabled all the info-center options regarding reporting and remote access.
From other posts it appears since in that state the truck knows it won't get a remote start request at any time, it doesn't need to keep a connection up waiting.
Others go for the whole disable power to the modem so there is no reporting - by pulling fuse 11 under the dash.
I've wondered if other modules are still expecting to send some data and with the modem off they may keep on for awhile attempting to get an acknowledgement from that module, or maybe the TCU itself reads the data from several modules and sends it up, which if no power the data read never happens too.

Anyway - some thoughts and theories on the matter that may help.

The software update may do about what I'm describing - cut off actions that are going to fail and stop pulling power attempting them.
We all hope it's more than that, I'm betting not.

Thanks HayBales. I'm wondering how you know so much about this, and very happy you shared it with me. I think I can take this info back to the dealer, and hopefully have a better outcome. I was getting a little concerned because I'm coming to the end of my warranty in March, and the fix probably won't be ready by then. Have a great rest of your weekend.

This kind of issue, even if not a recall, will be a TSB, if you have the issue you'll get the fix. Which as a software update will likely have a few more updates to other modules too.
Only question is timing to get a free battery out of the warranty.

Took my 2024 Maverick Lariat to the dealer yesterday. Deep sleep mode was happening on every trip within minutes of parking the truck. Service department at the dealer ran tests and verified my concerns. They found SSM53087. Tested battery and it passed. Charged battery, preformed BMS reset and informed me that I had to deal with the issue until Ford issued an update. We will see how long it goes without deep sleep. I am not a happy camper because last year after multiple trips for a steering issue on my wife's 2022 Honda Civic the dealer repurchased the car as a lemon after she contacted Honda Corporate. A week later we received a recall notice about the steering issue. I hope Ford does better than Honda.

Keep a jump pack with you if you don't already have one, just in case.

Thanks. I have one.

Service Manager wrote a reply to an email I sent to the dealer this morning. Here is part of his reply.

"I have submitted your VIN to Ford for having the symptoms outlined in SSM53087 applying to your vehicle specifically. As more reports are submitted to Ford for this concern, hopefully it will expedite the release of a repair. Regretfully, that step can oftentimes be missed, which prevents Ford from knowing how widespread a concern is. "

I jump-start my 22 Maverick every time I stop and turn the vehicle off. The dealer tells me to wait until Ford sends out a fix. Yesterday, after jump starting, and beginning to drive, Idiot lights and bells went off and the vehicle slowed down to 20 MPH and won't accelerate. Towed to the dealer this am. I have had to jump the car 44 times in the last 25 days. Not acceptable.

No. It's not.
park it at their place blocking their main entrance with a dead battery and tell them they need to fix it properly, at least replace the battery that will buy you a few months, or buy back the truck.

This has been my concern with the SSM.

Misapplication of it as an excuse to do nothing.

Though your conditions match what it's talking about - drained battery.
They are supposed to charge it, then test it.

I'm guessing your's would fail.

Which the solution isn't to wait until a fix.
That's the fix if the battery tests good.

Ya, and I'm betting with that SSM they really have a majority of dealerships not submitting reports of problematic but not failing batteries.

I'd sure hope of all the pieces of info likely submitted to Ford upon parking the truck, and first drive of day data - would be last seen voltage.
I can't imagine that looks great from many trucks, even if it is within their low desired spec's.

I have had this same problem. I am on my fourth battery!!! Each time (every five months or so) they first fight me on it telling me to go for a long drive on the highway or sometimes they charge it and send me on my way. Eventually the check engine light comes on and I finally talk them into changing out the battery. Like I said I’m on my fourth one which was just put in this week.

Hey - found this old thread and curious if you got another battery under warranty?

And did you end up turning off remote functionality since the cell service was usually bad in your parking spots?

 

[nobeer]

My battery was never replace. Just tested and charged. This was in the fall 2024. They told me about the SSM53087. Deep sleep mode was intermittent for a while until doing it 3 of 4 days a week ago. Texted service manager who gave me SSM53648 which was issued recently to replace SSM53087. I started a thread on SSM53648 last week. I got a survey from Ford last week and told them I was very displeased in their handling of this issue.

I have tried various methods including the turning of of the remote functions. I don't clean the truck with the key-fob in my pocket. I have found out that cleaning inside and out will cause mine to go to deep sleep. I charge the battery every once and a while. Opted not to do the AGM battery swap because I don't think it will solve my problem. I think it software.

Just waiting for the update. I am planning to have them look at the truck in early May based on SSM53648.
