In my several interactions with Text Messaging Customer Support, I have found this service, while responsive, to be fairly useless with inane responses and plenty of outgoing referrals to other support services within Ford. Afterwards, it takes several iterations just to get back to closing out the conversation....annoying.

If it's a non-urgent issue the knowledge and response on this board is head and shoulders a better resource, IMHO.
While it is undoubtedly an AI Bot, I found it to be helpful. It did take a minute or so to provide my 12V SOC, but that was not unreasonable. It will also check in on its own every month or so to see how things are going, which can be helpful without being too intrusive. It's not useless imho.

Didn't know you could ask about 12v SOC. That's slightly lees cumbersome than firing up Car Scanner. :wink: Any other neat tricks like this you can share? Maybe I'll end up embracing this little bot. :geek:

Sure wish they would just put this 12v metric on one of the screens.

I would get the 12V battery checked. Do t just check the voltage. Get a load test or internal resistance check done on it. Most auto parts stores will do this for free. The Mach-E has a TINY 12V battery, and if you are o my plugging the car in once a month, it might not be in the best health. Also, it is not uncommon for car batteries to fail after 2-3 years. The 12V battery in my dad’s Bolt EV failed after about 13 months.

I make it a point to charge up all of our vehicle 12V batteries at least once every 6 months with my 10 amp battery charger/conditioner.
I have a 2023 job 2 and the only issue I had was the 12v battery. I had one or two minor issues with it and when I was at the dealer to replace something I broke (by accident), they did a quick inspection and tested the battery. They said the battery didn't pass the load test and replaced it right then and there. I have 34k miles on it right now. No other issues. I will say, out of the last 10 new cars I have bought [mostly fords], 7 out of 10 had to have the factory battery replaced between 1 year and 2.5 years. Personally, I think there is something funny with factory batteries, but that is my experience. Non factory batteries, even the same brand like MotorCraft, work great once replaced.

I wonder if Ford got a bad batch of batteries.

And, as always, after letting it "cool down" in the garage for 2 hours (it's been 90 degrees in there, and the temperature reading on the touch screen has reached "116 degrees" when its been outside!).

and, in the two days before the failure, I got charging "error" messages twice on my app while it was plugged-in at home. But when I went into the garage both times, it all appeared to be working
I haven’t had anything like you are describing happen however I have been seeing the charge error on my phone only to see the car charged normally and the error doesn’t show when I do open up the app.

are you using a “delay charging” feature directly on the charger or using delay with the vehicle’s built in software ?

I delay mine on the charger. I wonder if that causes the error.

You can get a charge error using the delay feature on your EVSE. The vehicle senses the charge cord has been plugged in but it's not charging...and can throw an error sometimes. I use a Wallbox Plus EVSE and an extension cord to reach my truck (parked on the other side of my car which is closest to the charger). So if I plug the extension cord connector in to the truck but the Wallbox is still plugged into my Mach-E, and I forget to unplug the car and plug the Wallbox into the extension cord, my truck will eventually throw a charging error...until I remember to plug the Wallbox in to the extension cord so the truck can charge.

Right, I don’t get it everytime so I’m thinking if the delay is over a certain amount of time the car will eventually decide there’s an error

I still need to test if having a long delay set on the charger itself is cause any sort of addition 12v drain

I've never set a delay on the charge. Just park in the garage, wait a couple hours, plug in at 120 volts and let the trickling-like rate go to work. As I've said before, since purchasing the vehicle, some unanticipated issues (unrelated to the vehicle) have prevented road trips; so, the car never has been L2 or L3 charged since it left the dealership.

I wonder if the circuit you’re using to plug the L1 into is shared with anything else. I would imagine the charger will max out a 120v plug. If something else is trying to share those amps it could cause the L1 to drop power and cause the random errors.

or.. others are right and the 12v is mis-behaving and it’s time to change it.

I think you might have something there. Pretty sure the charging is on the same circuit as the garage fridge and garage door opening mechanism. And it did get up to 90 degrees in the garage.... I'm going to keep an eye on this. Thanks!

Update: Saturday morning, June 21, 2025. Summer's "official," but it's been in the 90s for the last couple of weeks before this "heat dome."
I get a genuine sense of concern, if not confusion/frustration from the dealership's Service Advisor. I don't think it's an affect (e.g., akin to a salesperson's 'let me run that by my Manager,' bs). My 12 volt battery was "tested" at the dealership and showed (among other favorable indicators, I assume) it was at "93%." I really don't understand how that can be, seeing how it's been cooking in South Florida's broiling sun since November or December 2023; and it's been even hotter these past couple of months. Demands on A/C surely have been spiking these last several days (with several more higher temps ahead).
In any event, I've been driving the car without any problems (held my breath retracing the drive back to that same doctor's office that occasioned the shut-down at speed). No issues apparent to me. And oddly (nowadays), I didn't get any "Charging Error" last night or this morning while it was being re-charged from 84% back up to 90%....
Service Advisor thinks the "Charging Error" may be with my Ford portable cord/converter(?), and advised he's trying to get me set up with a "loaner" so I can bring the car and Ford portable charger in to be checked.

Not sure why the use of AC would affect your 12V battery’s health. All of the 12V loads, which the AC is not part of, are supplied by the high voltage DC to low voltage DC converter. The AC compressor is directly powered by a high voltage connection.
