Features no longer working

Di you honestly believe the app and the technology behind it in the vehicle and at Ford are "free"? It is built into the price of the vehicle. So, yes, we paid for and expect the features that were advertised with our model to be available and work as advertised.

I was going to edit my post to Ken saying “ZABSMAV is actually accurate/correct - there is no such thing as a free app”

The above bolded is incorrect. Categorically incorrect. I'm sorry.
For what seems some decent % of drivers, that's not correct.

While there are only a few of us I've seen logging actual values - we all do show that there is NO big drain that causes a low voltage battery, with issues getting recharged back up to acceptable levels.

No - it's a constant application of NOT enough charge, that slowly allows the battery to reach levels that sulfation happen at. Now you start getting issues with charging, retaining a charge, ect.

I can provide logs of almost 2 a day drives after my new battery was installed - showing the slow decline of initial Voltage before truck is on, to decreasing SOC%, and decreasing Amps and time at decent amps, to charge it back up. I daily noted the initial Volts and prior sleep time Quiescent mA average to show there was no parasitic drain - ever.
You can watch the BMS system's own PID figures of cumulative charge and discharge change and seemingly increase as you'd expect almost equally, with charging almost clicking over first.
But a slowly degrading battery proves those readings cannot be correct.

Until Ford and techs realize there is a difference, and this has been my concern - the intermittent battery drain SSM will be the end of the story - and very few actually have that problem.

Ford had a separate update on certain Maverick hybrids to specifically address a deep sleep issue. I'm not sure which years. But it involved updating the software on a different module. I can't remember off the top of my head which one. Your truck may have that issue. I've made it a practice to update EVERY module where there's an update available in problem Mavericks . Again, we've only had an unfixable problem with One. All the others have been fixed. This Maverick has arrived in various states of charge ranging from 95 to 60 because it's driven for over an hour. When it arrives, it may go several days with zero issues. It may partially discharge to where it goes into deep sleep and remain there. Or It may kill the battery completely. Whatever problem it has is beyond us. If it's a problem with the charging strategy, we can't do anything about that on our end. I'm sure Ford has some test vehicles and has gathered information from hundreds of techs based on what they've asked of me. They've actually informed me of information related to the vehicle I'm testing that I didn't realize they had.

So you "solved" your deep sleep problem by disabling the use of the Fordpass app? Sorry, but that is a hard NO for us. We paid for the ability to remote lock and unlock our vehicle and the FordPass app is the ONLY way to remote start our Maverick. The dealership told us that Ford eliminated the key fob start buttons on that run of Maverick Lariats as they said that was replaced by using the FordPass app.

I removed the wheels on my Maverick, you wouldn't believe how much money I'm saving on gas.

Yeah, but come on guys “technically”, you do pay a fee for some apps initially or a monthly fee. With the Ford Pass app…. it’s neither. So…free free free…FA free free.

Thank you Darryl for your insight, being on "the inside", which brings a whole new dimension to our inquisitive minds.

I've always wondered why the update all modules wasn't taken as a standard approach.
Should help any future issues as there may be little to no time wasted with doing an update then, just to see if whatever issue remains, and it does happen to.

Since the issue many of us are referring to is a longer term issue than battery drain in 3-1 days, I'm wondering how it's known that the fixed ones are really fixed - unless that drain was all they came in with?

Because many on this forum had the non-intermittent non-battery drain issue of undercharged - and they got the ACCM update.
And a fully charged up battery, and BMS reset, and BMS relearn later.

And down the road not too far - they had the undercharged battery again - causing the battery saver items to kick off, those with Fordpass saw the deep sleep alerts again.

Since the 25MY manual for both EB's and hybrids (prior MY was EB only) - states that installing a battery with different specs requires a technician to modify those values so that proper charging takes place - have you seen specific instructions on what exactly those fields are to update?
There's a bunch of PID's dealing with battery info for spec's - and for pre-25MY at least hybrid, few to none are selected as an option.

There are a few reasons why it might not be a good idea to update all modules every time. 1. While rare, Some updates have bugs themselves and can introduce other problems. 2. While most updates take just a few minutes. Some take longer. In some cases they may take an hour or more. There's one update on some F150's that can potentially take 5 or 6 hours. 3. If it ain't broken, don't fix it. Unless it's a recall or very common issue, The vast majority of vehicles will go through life never having the problem the update addresses in any area besides the one it was brought in for. Even the quick updates pay 0.3 hours of labor, multiply that by multiple modules and hundreds of thousands of vehicles, it adds up. 4. When many customers know we updated something, they swear that every since we did the update, their car now acts funny

. . .

After my 3rd battery failed with all recalls and TSMs already applied, they updated all modules to current software levels. While doing that, they blew the TCU without noticing, and I only noticed it after a week when the Ford app stopped being updated. Replacing the TCU required most of a day and full disassembly of the dash.

The Ford software updates are flakey at best, and successful updates are extremely problematic. Ford needs to redesign their whole software system and infrastructure to be far more production-quality than it currently is, and make all updates into just routine overnight things like Tesla and others do. Geez, you'd think that these wannabe developers previously worked at Microsoft or something...

Hey Darryl, yesterday my 22 lariat with 14 month old BXT99RT4A MAX series warranty replaced did this on shut down. Double lock did not finish radio turn off just snow on screen. Should I have remote service come out to read any error codes or can I drive it in to have them read? Took 7-10 minutes for screen to go dark and some additional time for lights below screen to darken. Pictures taken through driver's door window.

I'd take it in. It's safe to drive.
