Dear Ford… why no 12v battery gauge?

The 12V in these vehicles does not need much attention? Where have you been? Obviously not on this forum. Why is there a whole thread dedicated to charging and reconditioning it? A FAQ thread about it? The 12V has been a regular PITA for a lot of people on this forum. It below a number of frunk covers and not visible/assessable does not mean it needs any less attention.

I agree with the original poster there should be info for it in sync or at least the app. Go to the web page is a bit ridiculous. 12V batteries do not last the life of the car a bit more (any) info on them would be helpful.
23 months and 34K miles of ownership of a 2022. Zero 12V issues. Not saying that other people haven't had problems, but those largely seem to be 2021 models.

Let us know what you think in about 12 months. ?

Although we shall see after the latest update if things are a little better. It seems it’s the 12v battery management rather than the battery itself that’s the issue.

Always helpful those that post I have had no problems in a thread that has nothing to do with that. Even if their post is of absolutely no help it should at least make them feel really good about themselves.

We should have 12V stats in this high tech vehicle just due the fact that the car does not let you in, does not boot and strands you when the 12V is dead.

This has been discussed in agonizing detail countless numbers of times. For whatever reason, the charge percentage listed on that page of ford.com is most certainly the 12v battery. You can find a long explanation of this in mach-lee's excellent 12v faq thread (it's in the very first post). https://www.macheforum.com/site/threads/12v-battery-faq.32744/
I remember first looking at that webpage and saw that yes, it had to be my 12V battery since it was not close to my HVB percentage.

But looking this morning at Ford's website, it shows the exact percentage of my HVB. I think there is a possibility that the number on that webpage no longer is the LVB.

Is it possible your HVB and 12V battery just happen to be at the same % this time?

My account still shows the 12V battery %.

Ah yes, I just checked again and now the website shows 84% while my HVB remains unchanged at 87%.

not sure about that. My 12v soc listed on the ford.com just now is 86% while my car HV battery is at a 63% state of charge.

I suspect that the 12V problems that have plagued the 2021 models is a function of the 12V battery management system sucking with those early models. And as updates have rolled out to those early vehicles, the 12V battery management has gotten better. That doesn't mean that the batteries didn't suffer damage, and thus might still need to be replaced, but hopefully at a slower rate than we saw before. In 12-months I suspect my 12V battery will still be just fine.

Notice that the 12v threads didn’t really exist 12 months ago.

I think it’s just a function of time. I’ve never gotten much more than 3 years out of any 12v battery in Florida.

I haven’t seen anything that shows battery management changed based on model years or any updates that changed it until the one a few weeks ago.

My 12V died the first week I had it (February 2021) and then numerous time after until the HVJB was replaced. The 12V also needed replacement due to abuse. I have verified that the web site 12V SOC mirrors what OBD states. The 12V dying is why I got an OBD in the first place.

For those without a 12V problem yet it should be noted that no 12V battery will last forever. With this car and how dependent it is on the 12V to boot, install OTA etc. it is only a matter of time until you see what a dead 12V does to this car. Would be nice when it does not boot to look at the app and be able to tell immediately why.

but clearly something has changed over time (whether in production or ota updates), the 12v issues were a pretty sizeable issue early on. and much less so now. I never had issues on my 21 but marvel at the comparative low state of charge some people with 21s and 22s mention . My 23, I just check it frequently out of curiousity. It's never been below 80% and mostly ranges from 85-95% this is vastly different from what a lot of earlier cars note.

You think it was worse a few years ago?

Early on it seemed we got a few “my 12v completely died” threads, but that was pretty rare.

Now we get tons of “my car won’t update because 12v low” or “low 12v” threads which I think are just a factor of time.

Seems like two separate issues.

early on before the 12v state of charge was recognized as an issue, but lots of people posting about weird things going on with their car, so yes I'd say it was worse early on. I also maintain that they did something to the 12v management system to eliminate the low state of charge a lot of people experienced in earlier cars. Like I said my 23 has never dropped below 80% and ranges typically 85-95%.
