Dealer says they've never heard of Maverick battery problems

[710-oil-614]

The replacement with an AGM and reprogramming the BCM is alone not likely going to solve the issue. If you read the description of the charging circuit for the Maverick it is only a trickle charger. Seems that they will need to replace equipment rather than just something as simple as reprogramming. If that were the case, why hasn't this happened in the 2022 and 2023 model years? This problem has been known for a very long time.

Do to you know if the dc-dc trickle charge is charging at its max capacity? And doing it all the time?

a software flash can change both of those variables.

Truck has been in sleep mode after sitting in garage for less than two days.

I called the dealer and they said they had never heard of maverick battery problems!

We all know dealers never ever LIE.

Agreed, it is not the battery. The battery may be the weak link.

There is a SSM #53087. Special Service Message. Here is what my repair order said the 2 times I brought it in. " 20 Confirmed. Checked Oasis, found SSM #53087. Engineering is currently working on a fix for an INTERMITTENT BATTERY DRAW, (read attached). Disconnected battery and tested per SSM. Battery test passed, reset BMS Reprogrammed BCE. No repairs at this time.

Tell the dealership the SSM number and look up in OASIS. They are stupid or liars. Part of the problem is that more people need to bring the vehicle into the dealership so Ford knows the actual extent of the problem. My dealer gave me the number to Ford Corporate and said to call and complain. They admitted to the SSM and said, Engineering is working on a fix due in the 1st quarter of 2025. My dealership told me keep bringing it in. My state has a lemon law and after 3 attempts and no fix, I can get a full refund including interest. My dealer is helping me because they want my business.
I have contacted a lemon law attorney and once I bring it in again the process will start.

It's not the BATTERY. Yes lesser quality batteries die faster. Check more posts. AGM batteries are dieing as well.
My choice is to push to get something done, not deal, with it and do nothing.
Make Ford pay.

If it starts don't sweat it. You'll get the software update to BCM and push the dealer to give you an AGM replacement.

I've asked my dealer to replace my battery like 3 times but they keep refusing. "We checked it and it was fine". No, it's not fine you jerks, I keep getting battery saver notifications.

The dealer won't replace it until it gets to 40% capacity at 100% charged. My truck is 8 months old. At my second dealership visit it was at 68%. I had to jump it recently and that's when I scheduled a second visit I'm not doing anything extra to keep it charged and from sulfating. Once battery goes dead and replaced then get power save again. It's lemon time.

If indeed true - hope you don't need a battery from them - who knows how long it's been sitting on the shelf!

Actually, date code is on negative battery terminal - you can know.

It can charge 15 & 10A as long as they want to.
There is no hardware limit, it's not just a trickle charger.

That's what the BMS system is Choosing to do because of the charging logic.
Based on some theoretical best practices. That don't work in the real world.

a software flash can change both of those variables.

It's been reported many times the change to 95% doesn't actually change anything.
Not on hybrid anyway.

Several that have the permanent battery reader installed have shown it still never get's past 70% charge, not even to the 80%.

And they've shown thru those reports that any higher charging rate still drops well before 80 or 95% is reached.

I'm betting a value not actually used in the hybrid. Just like several other battery related values aren't actually used.

They are considering your ability to read truck stats and remote start as optional items, they believe they don't have to work.
That's all the deep sleep effects - disabling the TCU just in case you let truck sit for awhile longer and it still needs to start.

If you bring in your window sticker and point out the Fordpass abilities - I'm betting it has a footnote "if available", or back to the old "you need to follow the advice and drive more" comment.

They have an out while the truck still starts.

Folks increased the charge capacity for the 12v they can affect the charge rate. But a software flash can and will.

This is also happening with some EcoBlast motors. There is a video on YouTube of a couple that has a 22 hybrid and a 23 EcoBlast that both have the problem.

I’ve never been able to get beyond 72% SOC on the 12v battery, which is a self installed AGM, even after putting my Genius10 on it for 48 hours!!!

I haven't seen those posts about Forscan changes to the charging rate.

Only the change from 80% to 95% "max" that it's thought to be.
But even that isn't max charge allowed, but the limit for full charge rate, before dropping to topping and then trickle charge levels.

And that's the change that doesn't actually have an effect at least in hybrids. That's been proven out multiple times.

After charger disconnect, was it allowed to sit for 8 hrs locked to do it's relearn?
That's the only time I got it to read close to 80%, after the drive into work bumped it up just a bit more.

The same thing happened to me. They tested the battery several times and said it was fine, but it went into the sleep mode virtually daily.

Two week ago, I took it in for routine service and asked them to check the battery. They said the BCM recall/update would fix it and also said that it tested fine again. The next day, I made a 150 mile round trip mostly on highway and yet that night it went into sleep mode again.

Fed up, I called again the next morning and told them that it's not working. They took it in straight away and installed a new battery...

That's my experience. My 2023 Hybrid Lariat is not even 2 years old yet... ;(
