Deep Sleep Mode - 12v battery drained dead [update: Mach-E jump started]

[DBC]

This is all speculation. The design could be solid, but there with a bug in the implementation. So after they fix this issue, its possible that the 12v problem is "solved". We just don't know the engineering details.

I'm not questioning the design. The problem is that it's highly unlikely that the engineers were able to foresee all potential issues. In this case there technically wouldn't be a bug -- the software is doing what it should.

I agree that the software fix may solve the current set of 12v problems. I don't agree that this will solve the 12v problem. The 12v is just a weak point that you design around and learn to live with.

This is probably marketing and aesthetic heresy, but I think all BEVs should come with a portable charger, easily accessible battery terminals, and a way to access both. LOL And I've never personally had a problem. I just know it's always a possibility so I make sure I replace the 12v battery regularly.

Donot use accessory mode

I wonder if the not plugged in warning was part of the issue. If LVB was low it might not have been engaging the contractors to charge. The trickle charger to the battery (with the cable attached) could be a good security blanket until the problem is solved.

I don't know bottom line it is not working right for sure. When it does not go into gear you are pretty much jimmered. Dealers techs jump box did nothing; glad they got yours early before it did complete die like mine. Optimism glass half full is I have built part pc's and they do not power on or throw BS and glitches continuously then a bios flash fixes all and they run for years. They should feed this all the power I have from the wall to begin then find power drains and fix them. I am of the opinion that there is no reason that it died and froze up when plugged into 240V.

I didn't have to use the bumper system as my driver side door was open.
I had to remove the rear luggage cover and the left luggage cover.
One could probably just connect the jumper cables or trickle charger to the jump points you picture. However, in my case, the car was trying to start up whenever the negative cable was attached to the negative post of the battery, so I disconnected the negative cable from the negative post of the battery and attached the negative lead from the trickle charger to the negative post on the battery.

Sorry I missed your thread/pics. Updated my post to include your link and these details.

I could get in and "start" it, but it gave me all kinds of alerts and wouldn't let me put it into gear. It was basically running in accessory mode.

Were you getting the sort of failures you see in my first two videos here?

Good news: I spoke with a member of the Ford engineering team. They believe that the software package in the newer cars eliminates this problem and mine will be getting this upgrade. They are working toward having this available as an OTA update for those cars potentially affected. Since they don't have it ready as an OTA yet, they are loading it on Marlin by wire. They are also installing some enhanced data collection to monitor it. Ford hopes to have Marlin ready for me to pick up this afternoon. ?

I also raised the issue that we need easier access to the jump connector points. They are considering that as well -- no promises.

Thats great news - I am not sure what they mean by newer cars - Feb 1 and beyond build dates? I hope they get the engineers to do this upgrade for the others that seem to have similar issues too.

Did you ever check your Sync4A versions before they'd touched it? Just curious if it was the same as mine (and others) reported so far.

Could be software versions that aren't reported though that they are upgrading.

I don't know the date but I would guess Feb 1 is fine. It may even coincide with the QC check campaign -- about Jan 9 IIRC (don't quote me).

So does that mean all the other cars will also have to get there's done manually? Explains maybe the QC stop and I guess some slipped through the cracks.

No I didn't but it's not the Sync4A that is at issue. Of course, when I get the new software, Sync4A may be updated too. The other good news is they think all my user settings will be preserved ?

I think around Jan 9 would be the grey area one s- i.e. not QC's but perhaps on the road somewhere and may have been missed. We dont know if the QC check was for this stuff anyway.

There may be a series of cars that will need an update, not sure. They also should be able to deliver it OTA eventually, just not this week.

True - Guess we really don't have means of knowing controller/software versions for everything.

Hoping that was it though and you can enjoy Marlin on your trip!

My Mach-E started production around December 16th. Wasn't officially "produced" until Jan 5th. No QC stops or anything, and so far no issues outside of instrument cluster display whine. (Granted I haven't driven it all that much).
