[jeffrol48197]

Jan 26 2026 New 2022-2025 Maverick - 2.5L Hybrid - Various Electrical Symptoms And/Or No Crank/No Start - Related To 12-Volt Battery Drain Some 2022-2025 Maverick hybrid vehicles may exhibit a no crank/no start condition due to a 12V battery drain after performing the air conditioning control module (ACCM) software update. Engineering is aware of this symptom and is currently developing a repair which is expected to be available in late Q2 of 2026. If a vehicle comes in for this condition, submit a Global Concern Report (GCR) and monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available. To submit a report, click on the "Submit Global Concern Report (GCR)" link at the upper right of the PTS Vehicle ID screen (VIN required) and fill out the form.

I fully recommend EVERYONE who's still having problems, 1. Get the ACCM update done just in case it works. 2. If it doesn't work, then bring it back in so we can submit a global concern report. It will put you vehicle on record as explicitly NOT being fixed.

Is the above a dealer thing or certified mechanic from Ford" ?

That's something the tech does at the dealership. That's why a person with the problem NEEDS to take it to the dealership. When we submit the report, we also give a brief summary of what has been done to the vehicle already. You don't want owners submitting reports of this nature given that a lot of owners haven't even had the ACCM updated and refuse to do so . Owner submitted reports would have no way to verify previous repair attempts.

Seems this SSM isn’t popping up for dealers

is it possible it’s still new or they changed the # since this post? Hmm

I don't think the SSM is released yet, and the correction is not due until Q2. However, this additional power leak problem will not resolve the real issue of the battery never getting to at least 95% charge and dieing a very early death as a result of the sulfation that this undercharging causes.

The vehicles have a draw. Every hybrid we encounter will eventually charge to 90-98% per the BMS reading as the other Ford vehicles do. The problem is that there is an intermittent draw that pulls the battery to below 80% or even will kill it fully. Once the battery regularly drops below a certain amount regularly, I think it confuses to BMS. Again, if we monitor the drain for an extended period of time, it will read an acceptable number then spike for a while. Sometimes it will drop again. Sometimes it will stay excessive until it drains the battery. Charging the battery more completely will not prevent the drain. The wide cycling prematurely kills the battery

Just had my 24 at the dealer about the battery saver message and interior lights not working after setting a brief period. The service report shows SSM 54519, and also mentions will be a fix late 2nd quarter.

Darryl...just curious if you work at a dealership? I just had my Maverick hybrid to the dealer for this issue. They said they just got the SSM today and told me there is nothing they can do now. They did not charge me anything and I did not get any paperwork documenting their work. I suspect the did not perform the ACCM update.

I do work at a dealership. And although Today's SSM 54621 is for a future date, the SSM (53801) suggesting that we update the ACCM is still in effect. The current SSM mentions making a GSR (if my memory serves me correctly report to Ford . The SSM is worded in a confusing manner. But it's actually addressing the vehicles that STILL have the battery drain AFTER the ACCM is updated. But SSM 53801 still is listed which in my opinion means it should be attempted first. If you're paying for it yourself, then you can choose to try the update that's available now and see if that works since it's worked for a lot of people. Or you can choose to wait until they have an update that works for the rest. If still under warranty, I'd DEFINITELY have them attempt the ACCM update now.

This is today's SSM. It's an internal document. So don't let them know where you got it . But Note the mention of the drain still occurring after the ACCM update. Also note that if a vehicle still has the concern, they are to submit a report to Ford. I'm not sure if it's to put the vehicles on record or to let Ford know the scope of the remaining problem vehicles

Here is the older SSM that's still in effect assuming you want to try that first. If it works, it'll prevent them from having to submit a report. If not, then they need to submit the report per the present SSM

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
