Well, it finally happened to me

In North TX, we're lucky if we get 4 yrs out a battery, flooded or AGM.

Michigan here. Typically 8 years.

People who think that the problems experienced with Mavericks and other vehicles are exclusively engineer issues seem to not be familiar with the dynamic between engineering/IT, upper leadership, and accounting.

Similarly, the people who think that the 2025MY resolved issues are merely a software difference with the previous generation that can be applied easily are very much under informed. The right fix is likely a hardware fix, but those are significantly more expensive during recalls than a software fix. And trust me when I say that Ford is doing everything they can to come up with a software patch before they resort to a fix that requires hardware.

Because, money.

I was all ready to take my 22 mavie to dealer today, was growing weary of the battery issue, and went out to the garage and you guessed it, it wouldn
't start. First time for that....so called in the calvary (roadside assistance) to jump start her...after starting, went right to dealer, they checked the battery and said it was no good...(this is the second battery I have gotten)...so brand new battery...thank goodness for warranty! Fingers crossed..

I have a 2024 Ford Maverick Hybrid I had issues with the battery going into sleep mode. I took it to the dealer they tested the battery it was fine they recharged it. Apparently I wasn’t driving it enough to charge the battery I ended up buying a smart battery 2 amp trickle charger I connected it from the terminal under the hood you don’t want to directly connect it to the battery I’ve been doing this every other day especially since it’s gotten colder so far I’ve had no more issues . There is a separate thread that talks about hooking up a trickle charger I connected.

I don't think it's the battery choice as much as Ford's management strategy of the battery; i.e. the forthcoming software update.

This It's the BMS software. Otherwise, it wouldn't be happening to people who've gone out and spent their own money on an expensive replacement battery, only to have the problem eventually return.

My '23 has not had any battery issues. But only because I keep it topped off periodically with a battery maintainer. This prevents sulfation, which has killed many of these OEM batteries, that otherwise, would still be fine, if they had been kept properly charged by the truck's battery management software.

Sorry for not having followed this issue, but is it unique to hybrids? If not, I will count my blessings.

I'd suggest level set expectations for what's coming in Q1 for software update.
Bad rumor has gotten around as to what it's fixing.

The actual issue the software solution is for. A battery drain, as the OP had, no start issue.
https://dot.report/bulletins/11009437

Some 2022-2024 Maverick vehicles equipped with 2.5L full hybrid electric vehicle (FHEV) powertrain 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 first quarter of 2025.

Contrast that one with this one which is about a parasitic draw.
They use specific words for specific cases which mean specific things.

Some 2021-2024 Bronco vehicles may exhibit a parasitic battery draw. This may be due to an interior door lock switch on the driver's and passenger's interior door panels. Prior to normal Workshop Manual (WSM) diagnostics, check both front door lock control switches for damage and/or proper operation. If a front door lock control switch does not operate as designed, repair as necessary. If no problems are found, continue with normal WSM diagnostics. For claiming, use causal part 14028 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual. If the draw is still present, refer to WSM Section 414-00 for normal diagnostics.h

Vast majority of issues being reported is batteries just slowly degrading until the system does what it does so you can still start it.
And a degraded battery suffers problems easier, lose a cell, get sulfated - so normal battery reaction from say an alternator system that has been undercharging for awhile - takes a nose dive quickly at the end.

ETA: would love a closeup picture of the BMS hanging on the 2025 battery negative post.

Some EB owners report their auto-start/stop no longer working - then again it seems many don't want it to anyway.

That is a battery saving feature.
And some EB owners report the deep sleep notices outside the expected 14 days non-driven.

Seems perhaps the AGM's in EB are better made, or hasn't gotten to the point for the problem yet.

Though there was a group of EB's that got the FLA batteries - those had issues.

When my auto start/stop quits working, I top off the battery with my battery tender connected overnight, then it works for a couple weeks or so. Rinse and repeat.

I'd bet that's one of the 1st things to get disabled as battery goes too low.
So your routine let's you miss the lights turning off sooner & sooner and deep sleep notices.

But good observation. You have AGM battery then probably, correct year to escape the recall.

Ok, now besides the 25MY, I'm curious about the BMS tag on these EB models. (side note - this is a driving safety level recall with stop demos/sales until performed)
If the solution already was done here - this ain't the hybrid's problem I'd guess.

Maverick
2022 February 3, 2021 through October 31, 2022
2023 June 20, 2022 through October 28, 2022

In the affected vehicles, the Body Control Module (BCM) and Powertrain Control Module (PCM)
calibrations may be unable to detect a sudden battery degradation while driving. If the battery
suddenly degrades during a drive it can lead to a vehicle that is unable to restart after an auto
stop/start event or experience a stall while coming to a stop at low speed. Either of these conditions may be accompanied by a loss of 12-volt accessories, including hazard lights. A loss of motive power can increase the risk of a crash.

Interesting the 2 phrases aren't really in agreement - "decreasing performance over the life..." or "sudden battery degradation".
Interesting how it is fixed - compensate for decreasing performance.
IE battery saver and disable auto-start/stop!

Got my THIRD warranty battery last month, 3/36 runs out in less than 3 weeks - I figure I will need to PAY for this software update, since I will be past the 3 years - hope they make it a Customer Satisfaction Program...

I think it's actually a recall? If so you should get it post warranty.

Ford has been throwing new batteries at faulty electrical systems for a couple decades now. I had 2 Fusions (not even hybids) an '07 and a '10. They both went thru 3 batteries , under warranty. I didn't keep either one long enough for them to be out of warranty. Seems as if the "techs" at the dealership can't fix things like parasitic battery drains, they just throw up their hands and put a new battery in. "All fixed", they exclaim. Until the next dead battery. I pity the future owners who bought the cars out of warrranty.

Intersting. I still have an 06 Mazda 6, made on the same line as those Fusions, and it has been fine for the 11 years since I got it. Just turned 180k miles.

At the beginning of this week, I had 2 days where the temps were below freezing, and low and behold...

Vehicle in Battery Saver Mode
Please drive your vehicle to refresh status and remote features.

Took it in, they charged it overnight, ran some test and said good to go and out the door.

I’ve had excellent luck tbh with Duracell platinum agm batteries from Sam’s club. Goes on sale often too. Mine is $170 or soemthing like that, when they do $20 off battery sale. Not including the 10-15 dollar core charge refund

I don’t know who actually makes it, but I like them, been putting them in all our vehicles none died yet.

Thanks for the info. Did they install the battery? If so additional price?
