FINALLY!! An upcoming 12v battery fix for hybrids!!!

[23grayXLT84]

Well, no big surprise here...

SSM 53648 2022-2025 Maverick - FHEV - Intermittent 12V Battery Drain When The Ignition Is Turned Off - Built On Or Before 17-Feb-2025

Some 2022-2025 Maverick vehicles equipped with 2.5L full hybrid electric vehicle (FHEV) powertrain and built on or before 17-Feb-2025 may experience an intermittent 12V battery drain condition when the ignition is turned off. If the 12V battery drains, perform a 12V power reset to the vehicle by disconnecting the 12V battery negative cable for 5 minutes. Fully charge the 12V battery and use the Rotunda GRX-3590 or DCA-8000 tester to determine if replacement is needed. If replacement is needed, fully charge the new battery and perform a battery monitor sensor (BMS) reset. Engineering is currently working on a software solution for this condition that is expected in the second quarter of 2025. Monitor Professional Technician System (PTS) for additional information and schedule service appointments for customers once the repair becomes available.

BUT, anyone with a Maverick built before 2/17/2025, will need the update, even 2025s....Hmmmmmmm.....

Man these people who bought 25s due to improvements sure are getting short end of the stick.

So a repair is not yet available but units built after 2/17/2025 are fine ? It seems like a report IS available.

Come on Ford !! Which one is it.

I agree.

This shows us they already have a fix which they started implementing in February. The rest of us just have to wait….

C’mon Ford, be better. If you can implement a fix on late built 2025s, you can get it to the rest of us too.

Hardware difference perhaps?

Or as prior post mentioned - that's the date the newer SSM was created, and they foolishly didn't make it a date reference to "until Now".

Most likely this. Anyone saying that the engineers are to blame for a fix being slow to roll out clearly has no clue what they are talking about about. Fixes that are hardware based have likely been shown to work, but hardware fixes cost money for both parts and labor to install them. Multiply out across multiple affected models and model years, and accounting isn't going to allow that.

So likely the much maligned devs are told to keep looking for a software fix. Sounds easy to you? Well, figure the multiple hardware configurations due to supply chain issues with high tech parts and it just becomes a lot harder.

But certainly vilify those folks who are doing their best under ridiculous conditions. It is after all The American Way to blame the hard workers that stand shoulder to shoulder with them and not the Rich Old White Guys in leadership who have no clue and are merely trying to prop up the value of their stock portfolio.

Which reminds me, it's time to go take my blood pressure meds.

I don't pay attention to the Job numbers and start/end dates of them.

Would that 2/17 date happen to be near a break in jobs perhaps?
New run, new hardware.
Except I would find it hard to believe Ford would eat the cost of the older modules unless that's when they happen to run out mid-job range.

Given how things tend to work, I wouldn't be shocked if the cutoff date has nothing to do with the issue being fixed but instead when the reporting cutoff was. We could very well see that date extended like last time when they started including the 2025 MY.

Could very well be, maybe a revised hybrid inverter? I know one of the Ford techs who worked on a Maverick in 2022 was not impressed with the design. The truck he was working on was less than a year old and the connections for the 12v battery in the inverter was already covered in corrosion.

When Ford replaced the 12v battery cable in my Maverick in 2022 (customer satisfaction program), they also found a faulty relay/fuse in the inverter. It didn't solve the problem though.

I'm wagering someone else's money on the Battery Sensor.
They sourced a 30 cent part instead of their normal 45 cent part during covid and just stuck with it.
And it's been inaccurate for actual Amp figures.

Though the strategy still seems to be a problem too. Made all the worse with low quality batteries.

Could be, but that wouldn't explain why some people do not have the problem. One owner on reddit said they owned two Hybrid Mavericks (same MY) that get similar use, one has the deep sleep issue, the other does not.

Interesting that sensor only used from 2020 and later, only Escape and Maverick.

I wonder if the Escapes since 2020 have similar issues, and the older ones not so much.

No, you are making a wild assumption. What will likely happen, given Ford being so famous at blowing smoke when they release any information on its ineptitude at engineering fixes, is simply miss the June 30, 2025 2nd quarter promised fix, and simply extend the vehicles covered to include all 2025 hybrids up to June. I'll put money on them doing just that.
