Recall: 25S02 12V BATTERY INSPECTION

[Leuf]

What exactly is going to take them until the second quarter to figure out the "parts" and "instructions" involved in replacing a battery?

I think it said 200k included, that is going to take a lot of parts.

You have an AGM battery so your battery is not subject to the recall. The start date of MY 23 was 11/14/2022 so you have one of the last MY22 built by Ford. From my understanding, Ford started placing AGM batteries in the Mavericks sometime in October 2022.

Mine was built in Sept has a flooded battery. So you are right.

Did you read the recall notice?

This thread is on a recall for EB models, not hybrid.

If you actually got a recall for the hybrid - please post it's number.

As Tim noted this is not a EB only recall but I don’t think the recall will effect my truck based on build date. All I have is advanced notice email that my truck may be involved from the NHTSA.

I probably shouldn't do this but I will post some screenshots of the recall as it reads so far.

To be fair that's all public knowledge. The NHTSA website publishes the Manufacturer Notice to Dealers along with the recall report and other documentation/updates more or less as it becomes available.

The recall report (and accompanying chronology document if released separate) are usually the most useful as it goes more in depth on the nature of the fault and work Ford did to identify it. It calls out it's the GAS powertrain (versus HYBRID ELECTRIC) affected and the remedy BAGM-48H6-760 reinforces it's for the EcoBoost. Although the dealer notice does provide the context that it's not "real" 2023MY that are affected, only pre-production units based on the dates.

I thought my 2022 had an AGM battery, but it's definitely showing that it's subject to the recall. Now I'm going to have to look, the next time I go out to the garage.

I was wrong! I have an EFB battery. Haven't had any issues, but if it gets replaced to "reset the clock," I won't complain.

I'm sure you are right. I'll wait to get the information from a Ford full bulletin to report that.

I agree.

And as far as I know the 2022 EcoBoost only got built with the enhanced flooded battery mentioned in the advance notice for this recall and not the hybrids.

It's not a BMS reset - it's a BS reset (Battery Sensor).

Per the manual, it's to be used when a new battery is installed, and that's the only time it's mentioned for use.
There are PID's for Days in Service that is reset to 0, and a cumulative Charge/Discharge tally that is reset to 0, and prior Voltage after a long enough rest. (Volts inaccurate after charging)
Those values among several are used in calculating SOC% and battery degrading with age.

In other words - declaring to the BMS system - here's a new battery, update all values to what you see now.
(and why it's such a bad idea to do it when battery wasn't even charged up - just chasing a new low into the ground)

The BMS relearn is only mentioned in the manual via the 8 hrs locked no disturbance.
Which for sure should be done after fully charging the battery as it says, or new battery installed which should be fully charged too.

I concur with this.
"Resetting" should only be done when a new FULLY CHARGED battery is installed. You are just lowering the bar and potentially making the problem worse doing this with an aged battery.

It's a 21, 22, 23, 24 . . .

I had the same thought and was going to post this.

This can be confusing.
The part numbers are nearly identical.

2022 EcoB. LX6T-10655-FA
2022 Hybrid LX6T-10655-BA

Those look like Ford engineering numbers and not part numbers to me.

Ford battery part numbers are more precise. Like BAGM-48H6-760.

An AGM battery, Group 48, which is it's size, with 760 cold cranking amps.

absolutely. I was expecting to have to replace this battery on my own sometime in the next 6 to 24 months.

My 2022 manual says that the relearn MAY have to be done AFTER RECHARGING or when new battery installation.

The word "may" can be replaced with "rarely". Rarely this should be done.
