If you want your Mach-E to get OTA updates - the SOC of the 12V (LVB) must be at least 80-85%

Where do you find SOC %?

This 3 hour thing. I am I, just, seriously, 3 hours if not more to try to get an update. Maybe the "Check for update button" should actually do something. I have a massive rant brewing but it like my futile attempts to resolve almost anything with this car is useless.

I feel this. OTAs were so easy with the Tesla.

Just hire some former Apple SWEs and get this stuff fixed.

I shouldn’t need an au 12v battery charger just to get an OTA on a car that cost me over $80,000. Ridiculous.

you use an OBD code grabber and CarScanner app.

I attached a screenshot of what it looks like inside that app

So I haven't updated since 10/28/2022 - so I called to ask about these preconditions - here is what they are without a doubt:

Preconditions:

• 12V Battery charged to at least 80% - drive for 30 minutes
• Parking brake on
• Headlights to off, not auto
• Wi-fi if available
• scheduled updates on automatic

It's definitely not 80% SOC for the vehicle - just the 12V Battery.

It is interesting that they say the failed update was the Blue Cruise update and it has been trying again and again since 12/8/2022. I have updated with FDRS at the end of 2022, but not received the UI refresh or anything that the car has notified me of - 3.5.4 is what the UI reports back.

So of the preconditions - the headlights and parking break are not on. So I am supposed to call back after a week to report if it was successful or not. My car was one that was stuck on 1.7.1 until I used FDRS myself to update. I'll update this if anyone shows interest.

Or your own FDRS account and all associated crap.

Over time batteries loose some power. A dead cell etc.. does that mean if you have a weak battery you will never get anymore updates until you finally buy new battery.

With this model you’d recycle your car for 1/10th it’s purchase price and buy a new one that has the updates you wanted when you purchased your first one. Don’t forget to add MachECare and a family subscription for the 360 cam ?

My 12V battery is always charged up and confirmed on multiple occasions via my trusty ob2 adapter. The car is always plugged in and charges 100%, connected to WiFi; light switch off, parking brake on, locked, etc. I can confirm that Ford's update sucks big times. Ford OTA's team reads off a script and doesn't even know the process.

There seems to be a guy on the back end selecting a bunch of VINs and adding them to an update batch with various retries. This would be my best guess as a person who works in IT.

This is highly likely!

Has anyone tried getting an external 12V battery (like people use for manual at home FDRS updates) and leave it plugged in to ensure the charge is over 80%?

My 22 MME is in EAP, but is still on 3.6.1, and has not received an update since Nov 1. And my 22 Lightning has not received an update since it was delivered in October, but I enrolled it in EAP 2 weeks ago. It feels like I have tried everything....long drives, park brake, lights off, ensured my 12V battery is over 80%, adjusting auto-update settings, disabling auto-update settings, etc., but nothing has worked yet.

I'm considering going down the at home FDRS route, but would prefer to not brick my vehicles...

I reconditioned my LVB over the weekend. Put it on 14.5V for a few hours until the current dropped below 0.05 Amps. Then I dialed it down to 13.6V and let it sit overnight. I am still waiting for 3.6.2, and this did nothing to get it to come.

As others have stated, your LVB battery state will only impact whether or not the update can be applied, not whether or not it becomes available for application. The car will download it, but if all the proper conditions are not met, it will not apply.

So if you don't see the little check mark at the top of the SYNC display, the update has not even arrived yet and the LVB SoC is irrelevant.

Wait that’s patch Tuesday? Every time an OTA server is rebooted a MachE gets an update…

So, somewhere someone had to have said. ‘4.1.2 is great only 4 people have complained. Great job guys! Take the rest of the year off. We’ll see you when the 24’s start rolling out.’

I've been eagerly awaiting this new holy trinity of updates and have continually failed. After reading this post last night, I completed my normal 30 mile commute to work this morning with the only variables being that I followed steps 2 and 3 on your list... and lo and behold the 3.6.1 update was already downloaded by the time I went out to my car for lunch and I was able to install it during my lunch outing. While I have to acknowledge that perhaps it was just a coincidence, I think those extra steps are likely what did the trick. Thanks for sharing!

Sorry for my lack of knowledge, but is there a way to gauge the SoC on the LVB? I don’t see anything in the standard MME screens. Maybe something by plugging into FORscan?

Would think if it was so important to receiving updates, that there would be an easier way to view state of charge.

You can monitor the LVB with a voltage reader that plugs into the cigarette lighter outlet (many options available) or use a OBDII scanner to read the voltage. The OBDDII scanner is helpful because it will show the LVB SoC in percent.

FYI: My car DID get the update to 3.6.2 last night. Hopefully 4.1.1 and 4.1.2 (and 4.1.3) follow in succession.

Well...4.1.1 showed up for me, just 4 days after 3.6.2 did!
