Priority Update: 23-PU0105-DC-CHG2: Improved DC Fast Charging

[RickLightning]

It is the 12v battery. Yesterday it failed on my Mach-E. OBD reader showed 58% SOC. I ran the car to 81%, and then manually applied it. Worked fine.

Drive, or just run the truck for 15 - 30 minutes. Or put a battery tender on it.

I left a jump pack on the LVB overnight. Both the current PU updates installed this morning via the Update Now button after at least 10 failures.

This update has failed for the last couple of weeks. Anyone else experiencing failed update? Above replies came in while typing... going to try the battery.

I have done all those things, without success. Tried immediately after a 60-mile commute last night and again this morning. Just now it failed with the battery charger connected.

I leave the fob in the truck every night in my locked garage. Never had an update fail. The last update I received locked the truck and rolled up one of the 2 open windows.

I have tried multiple times after 30+ minute drives and it is still failing.

Charging the 12v had no effect except it no longer comes up with a failure message. Oh, and now the display randomly scrolls through the recently used apps.

@TaxmanHog - this PU would be worthy of a poll.

Seems like another flawed update from Ford. They just can't get it right. Mine has failed 4 times now and I typically get most updates on the first day or two and they install first time. This one looks like it is going the way of the DTC update from last fall.

Quite sad - they can't do a simple battery check and issue a charge cycle for the install.

I drove over 150 miles yesterday. Plugged the truck in when I got home. The truck tried to automatically update at 1AM, when it was close to 90% SOC and failed. Testing voltage on the 12V indicates it's fine. I could put a battery tender on it, but doubt that will help and I'll try that tonight.

I'm thinking there's some other set of conditions with the truck that need to align, that we are not fully aware of. Hopefully the trucks report enough data back to Ford and they can get this sorted out.

Got a notification of it today. I manually updated it while out shopping. No problems. Then another update became available. The one ending with DET. I’ll update that later tonight.

I have lost track of how many times this has failed. Never had an issue with any other updates. Kept phone and fob on other side of house, have driven truck to charge 12v battery. Tried manual updates. Watched screen from outside of truck, it starts, then 3-4 minutes later screen goes blank and update fails. I have followed all suggested steps. Assuming some day Ford will fix this.

Mine came in a few days ago. I don't usually charge via DC, but it good to know that there are updates coming in for that.

This update finally installed today. I'd say I'd had about 25 previous failures.

What changed? I reset the 12v BMS on my truck last night !! Simple - Turn accessory mode on, flash the headlights 5 times and then press the brake pedal 3 times. The battery icon on the dash will flash and then come back solid. I truly think this was the difference maker.

So one short drive today, hit the button to install and it did while I was eating lunch.

All of that seems so good. So good, that the next release started downloading immediately, which I believe to be 23-PU0306-BCF-DET. I got home, hit the install button and now it has failed twice. Oh Ford, how you love to repeat your problems and not fix the root cause.

I'll give it a day or two and then try resetting the BMS again.

I'm still stuck on this one. Nothing I've tried has allowed it to install. I guess I'll reach out to Ford... Not critical, but I just want to make sure the updates can continue to flow and I'd rather my truck not get left behind. Yeah it seems the -DET update version comes after this one and some are having issues with that one as well.
