Had a similar issue with another other Ford vehicle with a battery, there were 729 vehicles worldwide. They knew exactly what was wrong: error in a temperature sensor of a specific welding unit which which could result in a damaged busbar over time due to the poor weld. The vehicles were worldwide, mine was originally from Germany but that causes issues: I never received an email/mail from anyone as it went to the original dealer which did not know me. I did get a warning though the local DMV equivalent so that worked correctly but by then it was already fixed as I read the ford service site from time-to-time.

Was replaced without cost as with this thing, no questions asked. Though the garage failed to bleed the cooling system (they said they did, but you can see if they did it in the Ford online systems, they didn't), resulting in the vehicle stopping once an air bubble reached the coolant pump and it overrotated (it will run for about 30 seconds before stopping).

In my case this also means I got a new battery after two years which is nice, but Ford probably tried to talk their way out of it thus it taking so long. If it's not a fire hazard it goes slowly ...
