From a Ford mechanic regarding the Maverick battery drain

"Hey just wanted to let you know that it looks like Ford finally released a software update to fix the battery drain. It looks like I was correct in saying it's the same issue as the Mach-e. It's a software update for the ACCM (air conditioning control module)"

Well, last week in anticipation of taking my truck in for the rear camera recall I replaced fuse 11/12.
Sunday when I opened the driver's door NO INTERIOR LIGHT.
I had drove the truck 60 miles Saturday
Last September, I removed fuse 11 charged my battery, did the reset and hadn't an incidents of No Interior Lights.
Video taken this morning. No lights.

I didn't have any problems until I replaced fuse 11/12 last week.
Just a coincidence I doubt it, I've gone 8 months without any problems until I replaced fuse 11/12.

Is the software update available OTA or do I need to take it in? You know the one where you have to sit in your garage ALL DAY with the engine "on" (draining your battery) and connected to your home WiFi ????

This is Ford throwing spaghetti at the wall hoping some will stick. They say that this "may" be part of the issue. The word "MAY" is is all one needs to hear to know that Ford still does not have a clue as to what is not allowing our hybrid Maverick 12v battery to fully recharge.

So………….
Some will say “What the heck, might as well get it done. Can’t hurt!”
Are they right?
Can it hurt?

The SSM includes 2022, 2023, 2024 and 2025 model years. They have identified a manufacturing defect (design defect). These have nothing to do with warranty. Should be covered in it's entirety, similar to recalls.

I believe that if you took the vehicle in for this problem before the warranty, there should be documentation that it occurred and was not fixed especially since Ford acknowledged the problem long ago and offered a couple of things to try in the meantime while telling us at our dealership to inform the customer that a fix was on the way. I know that our dealership would probably find a way to get it done under warranty IF there’s a record of a prior attempt. (Often multiple attempts). If your dealership is uncooperative, I’m sure you can contact Ford for assistance. They should do so without resistance since it’s a simple software update.

This is a known design defect that Ford has now publicly acknowledged has existed since the inception of the Maverick, so it shouldn't matter whether or not a owner took it in to report this, since prior to late last year, Ford did not even acknowledge that there was a design problem (Probably kept it hush hush to keep sales rolling in, as bad press always hurst sales.). They have now publicly acknowledged that this design problem has existed all along. ALL owners, regardless of mileage, or secondary owners, should be entitled to whatever modifications and repairs are needed, at Ford's expense, to correct the design defect.

Not an infotainment upgrade that can be done via wifi.

Mobile or take it in.

No - correcting an issue in a module. Probably some lose code - always a good thing.
Well, unless they caused another issue...

Issue may or may not sounds like be the module remains powered on or causes something else to be powered on, sometimes - causing an intermittent battery drain.
If never experienced, doesn't mean it might not some day.

I don’t disagree. Nor do i decide what Ford does. I’m just answering the question the best I can based on what happens in routine situations where an unsuccessful repair attempt was made prior to warranty. I THINK ford will probably ultimately fix all those that had problems. But sometimes it takes a while for them to reach that decision. I’m simply saying what should work NOW. I won’t be surprised if they offer a “customer satisfaction “ field service action (voluntary recall) that gives customers a certain window to get it fixed for free regardless of time or mileage. At THIS point it a SSM (service message) . They often do those PRIOR to taking it up a level. I think it’s to be 100% certain if their fix actually works in the field before having ALL those affected vehicles come in only to have to redo it again If it doesn’t work.

At THIS point it’s only an SSM (special service message) which is simply a suggestion. And if this indeed works as they believe it will, they’ll probably upgrade it to a TSB (Technical service bulletin) which then REQUIRES the technician to perform this repair PRIOR to trying anything else. And based on those results (and sometimes customer demand) they’ll make it a (fsa) field service action commonly called a recall. But they will sometimes make it an “as needed “ recall where we perform it only if the customer has an issue. Other times they will have us to perform it on all vehicles if the customer brings it into the dealership within a certain timeframe. The best case scenario is where they tell us to perform the recall on all vehicles that are POTENTIALLY affected for virtually forever.
