NHTSA Complaint #11539777 — 2021 FORD MUSTANG MACH E

I had my 2021 Mustang Mach-E updated with the recall software last year. In July of 2022, my High Voltage Battery Junction Box (HVBJB) still failed, giving me a service vehicle soon and SEVERELY reducing power WHILE driving. I was on the freeway and my car just started reducing speed since I was trying to pass someone and I almost hit them. I received the new HVBJB from my dealer and had been fine since. Then a couple of weeks ago, I received the errors AGAIN with this "new and improved" HVBJB that Ford said is more robust and not supposed to fail. Same thing, on the same freeway I commute (73 toll road in California). I was passing someone and the car hit me with all these errors and SIGNIFICANTLY reduced my power. Like 66% reduction. I had to get back into my lane and was able to get back a safe speed but you basically have no power to pass. This is unacceptable. I received the "new" part and yet get a failure AGAIN? On a normal commute, not at the track, accelerating to show off the EV acceleration, just DRIVING! Please make them fix this for real. My dealer said there was a new bulletin that came out after my first repair that has an updated part number, but it is not a true revised part, meaning the internals are actually differnt, it is more a housekeeping part number update due to something as simple as the sticker being in a different spot, some backend thing, etc. There has been no revision to the components that fail since they "fixed" the part back in 2022.
