Thanks for the insight. It is odd though that, I usually don’t have problems with updates (well, since the very early days). It seems odd that this just started. My use of the car and my charging habits haven’t changed.
When I called the Ford OTA hotline they told me that the latest round of updates that we have been having trouble with have the minimum 12v battery threshold prerequisite set higher than previous updates because they are bigger updates that use more 12v power. The minimum threshold is now 95%. Not sure what it was in the past.

Got this update earlier today. After a year of being months late to receive some updates, it’s weird to now be on the leading edge. The last 4 or 5 I’ve received within a few days of release.

Now I look forward to another release that actually makes some substantive enhancement or bug fixes. That hasn’t happened since the UI refresh.

No, you got the 21B36 OTA, not this one.

23-PU0314-DCM-LAT is a door latch module update to prevent false alarms.

(DCME, DCMF, DCMG, DCMH updated to - AM)
The release notes make it seem like a GWM update, is there not one? Crazy.

When did they start giving out useful information?

The OTA hotline was very good. This is different than the general support number.
Contact the OTA team at 833-389-0848. Their hours are 8:00 a.m. -11:00 p.m. EST (Monday-Friday) 8:00 a.m. -8:00 p.m. EST (Saturday). In the event, the phone number(s) do not work, call the CRC at 800-392-3673 and say " Over the Air Updates for Mustang Mach-E" for example.

This is nonsense (the dependence on the pitiful 12V battery). Clearly there is something systemically wrong with the OTA scheme and / or the design of the low voltage system if the system can’t automagically condition the 12V battery when an OTA shows up on the car’s doorstep. Here’s an idea: use the stupid buffer in the HVB. That way we wouldn’t have to listen to people whine about “vampire drains”. If an OTA really requires more than 10% of a 99 kWh HVB; then something is wrong!

Just got this too. I feel so much smarter…. Step backwards in release notes ….
This is actually a step forward from "less uh ohs and more phews". At least they're talking to us like we're 10 instead of 5 year olds.

Lots of chatter here about getting the update, and what it may mean for further updates, but precious little about how/if the update improved anything on your vehicle. [/rantoff]

Along those lines, I have found a marked improvement in using PAAK. Since the update I have not been getting the warning of "No Key Detected" while backing out of my driveway (using PAAK). I am also having much better luck in re-starting the vehicle after a short stop/exit and not having PAAK fail to work and requesting that I enter my passcode. So congrats to Ford if they've solved these issues. I will have increased faith in using PAAK under all circumstances.

Now...if only I could get my phone to connect when approaching the car more quickly (even when booting the app before arriving) so that I am not having to wait to unlock the doors. This is embarassing, at the least, and annoys the bejeebers out of my (waiting to get in) wife! Please Ford, improve on this and lessen the chippy discussions with my SO (sadly, only one of many SO chippy discussions :)!)

Lastly, I would love a feature that, should a driver be using PAAK, a little reminder would pop up to take the phone with me after shutting off the car . I've left it behind in the charging space a couple of times and fear that someday someone will hop in an drive away! :eek:

Please show us the mass market EV that you engineered.

I am just saying there is a lot of overhead associated with tapping into the HVB. The overhead is what causes the vampire drain, not charging the LVB itself.
Mostly because there is no way, in the current vehicle architecture, to turn off individual modules like the BCM, APIM, etc. It's all or nothing, you wake one to do an LVB charge, you wake all. It's a problem that can't be solved with a software update, it's a legacy hardware design issue.

So you basically have the car completely powered on when charging the LVB. This is a substantial drain, and you wouldn't want your car live for a few hours doing nothing but charging the LVB. If you did, the next forum topic would be "Why did my car lose 5% charge just sitting doing nothing?"

So when you are driving, LVB charging is just a small "other" HV battery drain. If you are charging, it's just an inconsequential redirect of power.

OMG, Ford Engineering sucks, that's why {Insert favorite automaker here} is moare better. They should hire some software people from {Insert favorite software developer here} to fix their junk.

I'm a {Insert random IT-related job title here} and Ford doesn't know what they are doing.

So Ford Engineering/Jimmy Farley knows they have this problem, what do they do?
1) Start planning next generation hardware/software architecture (done, FNV4)
2) Hire someone to lead next gen arch team (done, Doug Field)
3) Hire software developers to build next gen arch (done)
4) Build next gen arch (almost done)
5) Install in super fantastically awesome new BEV vehicle (wait about two years)

I got this update a couple days ago, after a couple of weeks of trying every trick I'd seen on line to get 4.2.6 to update, it never did, however this update did go thru and now I no longer get the unsuccessful 4.2.6 update and my sync 4 says I'm up to date now. 4.2.6 was the first ota in two years that had trouble updating. I'd point out the install I got was 21b36 - 23-pu0415-blm-vis

Just thinking about it, this must have been more than a GWM update. The GWM updates in the past have always been rolling updates because it’s an A/B module. This one was an inhibit update, so there must have been other modules.

I think It also updated the door modules
