Mach-E recall. Deliveries halted. Oops...
From the Mach-E forum...
Apparently every unit built up to 5/22/22 will be subject to a recall around the high voltage battery "contacters" welding themselves either open or shut.
All deliveries are halted. They don't know if it will be a hardware fix or software fix. Maybe both?

Yeah I know. Hopefully it's an easy fix. I just read on MSN that it will be an OTA software update, but I don't see how a software update will fix an overheating contact, unless it's a software bug causing the issue

Reading the recall again...
Should the contactors weld closed while driving, a powertrain malfunction warning light will be illuminated on the next drive cycle, along with a no start condition

Software limit on power output would "fix" the problem.
Reading the recall again...
Uh, Ford. Why would you code it this way, waiting for the next drive cycle? This means if the fuse welds closed and you happen to crash the HV battery will stay live no matter what. How do engineers let stuff like this get into production?

High volts/amp switchgear is bulky and sometimes heavy so I'm sure it's a engineering design nightmare to keep it light and compact.
We don't see this problem a lot on industrial machines because it is usually way overbuilt just for this reason.
The machines don't roll on wheels so no real constraints unless an machine builder oem goes cheap on the copper and switchgear.
Looks like they are making revisions on stuff.

Good question. From what I've read the bus bars in the battery pack are puny they can't sustain what the batteries themselves can put out. I wonder who makes that main fuse its only job is to blow when needed not weld closed that's the worst failure possible for such a device.
