Too much regen is a simple SW fix. The SW engineers just didn't think of that failure mode when they coded the regen function. Looks like the reliability guys also failed to fully test that function. Typical new platform bugs.
It seems that the fix is so simple that it is only going to take Ford 3 months to do it.
"Annie Sønsteby, Ford Norway information director, says the Mustang Mach-E braking issues can be handled with an over-the-air fix. Unfortunately, with Ford, that means you still have to take it into a dealership to get it. So, maybe Ford should just call it a “software update at the dealer” update instead. The good news is that the over-the-air updates will be starting around October 2021. So it will be happening, just not now. "
