I haven't been following this thread but have noticed that I had to reset the default charge percent after a couple times over the past 10 days charging to 100%. I had to reset to 85% and it works fine. as taxmanhog posted his, my recent updates are here for my 2023 Lariat.

I'm at 23k miles and absolutely love this truck.

So after seven days and nine (9) tries to install this OTA update, I finally succeeded just now. Many tries with many sequence variants to get the 12V battery up to top charge and for it to stay there... using the Clore charging & supply functions, and the 120V overnight Level 1 charging, and leaving the truck "ON" overnight, and sacrificing frogs in the moonlight, etc etc.

At times I felt like Gary Sinise in the 1990s Apollo 13 film, when he was testing stray voltages in the duplicate lunar lander module to save the in-flight astronauts.

But the good news is that all my radio presets stayed put.

That's more than Gary Sinise can say!

FYI for others' use: when after right the update I reconnected my ancillary electric stuff like the dash cam, the rat flashing motion deterrent and the aftermarket 12V battery Bluetooth monitor dongle, I saw that the 12V battery showed a 49% state of charge. This despite it being on the Clore supply all morning prior to and during the update at a 14.3 Volts level.

Meaning, this update drains the livin' snot out of the 12V battery during the 20+ minutes of installation. And my 12V battery is only 6 weeks old.

That's why this one is giving everyone so much trouble and keeps delaying for 12v. It almost needs 1.21 gigawatts

ahhh...That explains why the entire city lights dimmed when my update was being applied.

This sounds silly, but did your truck ever get the battery monitor (on the ground terminal post) replaced? Even a good battery would show wrong with the defective battery monitor.

I did check with the dealer back then... I honestly can't remember but I think they might have replaced it.

Here is the post about it where you can find the model numbers of the bad and good replacement parts. Its easy to check on top of the 12V battery.

Thanks for this! I had no idea this was an issue but sure enough, my truck that fails 90 seconds into the update has the bad part number.

Very cool that the corrected part is now 2-3x more expensive than it was just a couple years ago.

You probably don't want to know that I bought the replacement on Ford parts for $30 before their supply ran short and they jacked the price. I am glad it will be a simple fix though, and that is the reason for your issue.

Yes thank you. I finally checked... my BMS has the -BA tail designator, so it's the replaced version.

I wondered why my Lightning was charged to 100% this morning. The 25.13.12 update installed overnight and had deleted my saved Charging Locations… @Ford Motor Company
