Locked Out, 12v battery isn't dead.

Does Fordpass show the current location of the car?

No. Shows the location were it locked up.

That is a good idea. This issue on my side is, since the the day after it bricked, Ford Pass has not connected to the car. If they get the doors opened and system reset, that should reconnect again I hope.

BnT_MachE, you are a trooper to keep your cool through this. It will get figured out.

I’ve been nervous before about this and now extra nervous. The update came and now I got the same plugged in not charging message and an alert about my 12v battery when I was out driving around. And when I say driving around I went to another city and it was a 1.5 hour drive. I have a 2021 Job 1 - something must be draining the battery.

That's the same thing I went through after 6.1.0. Dealer had it for 5 days and said that there was something wrong, but couldn't find it. But after getting the car back the rear hatch doesn't work right. Will only open if you first open the drivers door and the kick to open will not work at all.

Update:

1. This past Tuesday the dealer forced their way into the Mach E.
2. Replaced the 12V battery and it drained within 1/2 hour.
3. They discovered a 25 amp draw on the battery.
4. Used thermal imaging on the battery pack and discovered no hotspots.
5. Are in process of tracing the 25 amp draw to correct the issue.
6. At day 9 of my 10 day rental period under warranty, hoping for resolution by tomorrow so we don't have to start paying for a rental ourselves.

Has anyone had their Mach E in the shop for a longer period of time? Is Ford flexible in providing extended warranty coverage for rental vehicle while in shop under warranty? If so, some feedback on the request or proper channel to address the issue if needed.

It has been frustrating. The Mach E has been in the dealers hands since 11/16/23 and they have only taken the 12V battery out, replaced it and have been tracing a 25 amp draw off the 12V battery for 5 days??? I know I am not the only car in the shop and understand there is an order of progress in service shops, but this seems ridiculous. I can only imagine, but would assume there are only so many 25 amp draws on that battery or possible combinations that come out to 25 amps. My ignorance on the small battery electrical system makes it hard for me to understand.

Thanks for all your help and feedback.

Have you called the Ford BEV team? Have they set up a case for you? That might help get things moving a bit, otherwise it's down to your dealer service dept calling up the ford field service engineer and suggesting different things to try.

Ford is great at monitoring these forums and did reach out in this thread. I confirmed with the dealer that their Tech was indeed in contact with Fords internal EV team on Monday of this week. I can only imagine the amount of wiring in the Mach E. Hopefully they can isolate the draw and figure it out.

Call the Ford BEV team. 1 (800) 392-3673. Explain what’s happened and what’s been done. They can escalate things if needed unlike the forum presence.

Will do. Thank you.

So the battery was dead?

Impossible, title says it wasn’t. Any suggestion otherwise was immediately struck down.

Battery wasn't dead with knowledge at time of initial occurrence. According to the Standard Operating Procedure designed by Ford and applied by myself and the tow truck operator who had jumped other frunks for access, if the 12v battery was dead, the frunk would open.

So logically, according to all knowledge at hand and according to the team who designed the system, no the battery was not dead.
The Ford tech could not get in using the alternative frunk jump either, logically confirming the 12v battery should not be dead.
Based on all knowledge at that time, that was the logical information.

That’s logical. Here’s a theory based on that:

The root failure causing the battery drain while preventing a jump from popping the frunk is in the circuitry that isolates the frunk jump circuit from the rest of the 12V system. Just a theory….

That is a great theory. Hope the Tech and Ford are thinking along that line.

Logically the same 25a drain killed your battery in the first place.

But we are all guessing here until they discover the issue and the fix.

Definitely curious how it turns out. That’s a serious amount of power that has to be going somewhere.

My guess is a short (chewed wires or something).

There was another thread a few months back where wires got pinched and killed his car. I’ll try to search.

I hope it is that simple. It would be nice to have it back. More anxious about paying out for a rental to get to work this coming week. Hope to hear some good news today. I would be interested to read that thread on the pinched wires or rodent issues. Thanks for the update.
