SSM 53801: 2022-2025 Maverick Hybrid 12V Battery Drain Issue Update Fix Released!

[Mareys]

I had my SSM AC software update done yesterday. It was there about 2 1/2 hrs not sure how long they were actually working on. I wasnt going to have it done until i was sure they had figured out all the bugs and had more feedback from MTC members on their experience but my warranty is up next week and the dealership called me to let me know if i have it done now, "ALL" i would need to pay is the $100 deductible. I think its ridiculous that there is any charge at all for this long standing issue. I have had 4 new batteries in a year. I did however have to make a quick decision as yesterday was the only day i could get it done in time. Fingers crossed that this is the "fix" I am highly skeptical and i didnt want them screwing up anything else. My truck over the last 6mo has been starting really well. Of course i go above and beyond, turning stuff off, driving way more miles than necessary etc I will continue to turn everything possible off and definitely before turning the truck off and will cut back on driving to see what happens! The dealer said it was the 2nd Mav they updated yesterday.

$100 deductible?? For what? SSMs are covered under warranty. Your dealer owes you an explanation.

If they are out of base 3/36 and have ESP extended warranty, they still have to pay their deductible, which appears to be the common $100.

I try to stay upbeat, but I can say that from past years experiences with other vehicles that I doubt this SSM addresses the problem. I have gone in circles now with several vehicles with similar issues. Most of the time it comes back to something waking up or keeping the vehicle awake. That could be an app on the phone, an app or function in the vehicle, or even the mothership pushing updates or collecting data. It has turned into a never ending soap opera that has had me battling 12v issues for quite some time. More times than not killing the telematics has addressed my 12v issues.

I see Ford is pushing quite a few updates on the Lightning lately and frankly some of those updates sound like they should be pushed to the Maverick. The one I just saw was an update for the app so that it doesn't wake the truck up so often.

trust me i argued strongly and have been a big pain in the service managers side during all of this. I told him about the SSM and what the update addressed, he had no idea. I had the update done so that they couldnt use that against me next time the battery fails!

Only recalls are always are always covered under warranty. SSM'S and Tsb's are simply bulletins to inform us of a likely or common solution to a problem. They are covered based on whether the causal part is under under warranty or not. In this case, I believe the cause of part is the AC compressor. As such, it is likely covered only under the 3/36 bumper to bumper warranty. With the $100 deductible, I am assuming that the customer has extended service plan. ESP has a $100 deductible.

The OP did mention his "warranty is up next week".

SSM 53801 2022-2025 Maverick - Hybrid - 12V Battery Drain - Built On Or Before 17-Feb-2025

Some 2022-2025 Maverick vehicles with a hybrid powertrain and built on or before 17-Feb-2025 may exhibit a 12V battery drain. This may be due to the software installed in the air conditioning control module (ACCM). To correct this condition, perform a battery condition test as outlined in Workshop Manual (WSM), Section 414-01 Battery, Mounting and Cables > Diagnosis and Testing > Pinpoint Test A. Service the battery as necessary. Connect a battery charger such as Rotunda GRX-3590 or DCA-8000 to the 12-volt battery. Download and run the "air conditioning control module (ACCM) software update" application in the Ford Diagnosis And Repair System (FDRS) scan tool. If the battery was replaced, download and run the "BCM-reset the battery monitoring sensor learned values" application in FDRS. For claiming, use causal part 19703 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

They have coded the causal part number to the a/c compressor, so it will be covered 3/36, and I already checked and it is covered under Ford Premium ESP also...(not sure about the other level contracts)

Thanks for the post, Jeff! I was able to take the SSM to my dealer today (June 2025) and have them apply the update. I got a new battery out of it as well. $0

...More times than not killing the telematics has addressed my 12v issues...

I pulled the Telematics fuse early on. That, and I periodically put the truck on a NOCO battery maintainer. Not saying this has saved me from having 12v battery issues. But, so far, I have had zero problems with the 12v battery system.

Well - you don't want to cut back on driving.

Outside of a short window of time between startups - each time you start the truck it starts the higher charge rate, at the level that actually makes a difference to charging up the battery.
Sadly that drops off eventually.

Higher speeds don't matter for hybrid.
Longer drives don't matter as the charging rate drops to trickle charge fairly quickly.

But don't cut back on driving for the sake of the battery.
Truck constantly listening for key fob, keeping connection to Ford active - there are draws on the battery 24/7 that require some drive time to fight them.

I am going to say, there are different problems that people are experiencing with the battery issue.
Most people are taking about sleep mode. (some say they do not have a problem at all).
Some are taking about the battery is not charging at the correct voltage all the time.
The AC unit being the problem. (There is a update for that). maybe it will help.
The BMS. (well it does set the voltage for the 12v system).
The battery is too small.
The battery does not get charged enough. (you need to drive longer). LOL
(15 minute drive to work for me).
There is a unknown drain on the battery.
The 12V battery is junk, or defective (they did have a batch of batteries with bad internal jumpers).
I think they all or a combination of these that are the problem, and are causing the battery to feel the pain. (feel the pain too much for too long, and the battery will die).

I still think Ford is still grabbing for straws trying to find the problem, (its been 3 years).

I only experienced the power saver mode two times, one day apart, around lunch time, never at night. (and that was the only two times).

Well for starters,
I think the battery is too small for what all it has to do when you turn off the key. ( it does not have a high enough reserve).

I have been monitoring the voltage and current for 4 months.
As for unknown drain, From what I noticed, the drain was a extended time after I turned off the key. ( normally is 10-15 minutes, this was 3+ hours.)

As for not charging at the correct voltage, I am not seeing it. (14.6-15.2V)
As for charging good for a while then dropping off after a while, I am not seeing that either. Mine is always showing minimum 14.6V no matter how long I have the key on.

The BMS can have a influence on charging incorrectly if something is not working correctly with it or how it was reset, and how the battery was charged with a charger.
( I did that, charged it incorrectly during a test, and the BMS thought it was charged (100% SOC), and kept the voltage at 13V, but the next day it was charging at 14.6V, after it did its reset thing at night.

One thing I have noticed, is when you turn off the truck, there is battery drain for a while.
I even turned my setting for head light off delay to 0 seconds, to preserve battery.


where is that electric current going?
Maybe the flux capacitor?

just checked my current data.
The truck was drawing 11 amps for 30 seconds, then 4.5 amps for 15 minutes then 2.5 amp for a half hour then dropped to 1.3 amps before going up and down a bit before it dropped to .02 amps.

And nothing was on.
no wonder why theses batteries are going dead.
After my 15 minute drive home the truck was still charging the battery at 4 amps at 14.6v

Built On Or Before 17-Feb-2025

whew. Ours was built on 2/18!

So are we to assume that vehicles built after February 2025 don't have these 12V battery drain issues?

Don't worry; they're still eligible for all of the other battery drain issues!

Ok I'll bite - What's a trucklette?

a misspelling of "trucklet", of course!

The OP did mention his "warranty is up next week".

Is it his bumper to bumper warranty or is it his EXTENDED warranty? If it's his bumper to bumper, then he should not have had to pay one penny. However if it says ESP warranty, then he will have to pay $100 deductible.
