All these stop safely now threads are scaring me. I actually miss the “my range is not as advertised” threads… those are more entertaining to read…

Just remember that the issue is on a handful of Mach e's.

23 is more than a handful.
seems to more likely happen to ER AWD. Didn't see SR RWD reporting this failure yet.
they probably need a more robust box to handle the amount of power ER AWD cars draw

No 22s had the problem yet? If I read the G sheet
Correctly.
Correctly.

I guess I'm missing something here. The poll shows 9 out of 73 vehicles affected. The poll closed earlier this month though and not sure why it wasn't kept open. And not having a Mach e yet I couldn't see the results of the google sheet.

My 21 ER AWD had the box go out and it has been replaced. I still have no working windows or interior lights. Has anyone else had those problems?

None here JBB. First edition, took Delivery end of month Feb 2020. Only charging with Ford Supplied charger. 40Amp 220 plug.
No windows, I hope they can get that fixed.

Another forum member reported the window issue but I think he said it eventually corrected itself. Have you tried disconnecting and reconnecting the LVB?

An owner of a 2022 posted on a different thread that s/he very recently had a HVBJB failure. My 2021 did a complete brick at 1500 miles. It is ER but not AWD.

I don't have a link but I've seen one 2022 failure on here so far.
He closed the poll and switched to using the spreadsheet instead. Not sure when the last time the list was updated.

Okay good, it's at least a decent population with various build dates.
Now I'm down to those that had failures, have any only used Ford mobile charger?

Nope. I never used the Ford charger, I'm using a 40amp ChargePoint Home Flex.
There's no pattern to any of these failures that we can discern.

PSA:
We have something like 23 owners who have reported this failure, but there are only 18 reports that I've counted to NHTSA. If we show a pattern to NHTSA, they have the power to require Ford to provide the actual maintenance reports for every failure of this part, and to order a recall.
If you have not yet filled out the NHTSA form, could you please go ahead and do so? Takes a short amount of time, they will then reach out to you via email and ask for specifics of what happened and for you to send in any documentation on what was done by your dealer.
