NHTSA Complaint #11461191 — 2021 FORD MUSTANG MACH E

The High Volt Battery (HVB) would have a fault in charging sporadically. When this happens, the vehicle can't start. All the alerts for safety features come on and says that it's in accessory mode only. It's no longer in my possession for inspection. It was approved for lemon law buy back and is now owned by Ford Motor Company. They've recognized that the 12v battery drains dead when this happens and they were attempting to replace the ECM module, Battery Control Harness, and the HVB junction box to remedy the issue. My safety was put at risk in terms of when this happened. It was between -25 to -40 when this was occurring and the heat doesn't come on in accessory mode. There was the possibility of frostbite within 5-10 minutes if I didn't seek warm shelter. The problem was reproduced by the dealership where purchased [they have all the documentation on file] as well as multiple people [more than 50+] in other states having the same problems reproduced on their Ford Mach-e vehicles as well at macheforum.com. The vehicle and components were inspected and ultimately bought back the vehicle by the manufacturer. No warnings lamps, messages, or other symptoms appear prior to the failure. They first appear when the vehicle 'decides' to not charge anymore. Since Ford has yet to announce any recalls / notices because of the increasing amount of people having the same issue. I wanted to inform NHTSA because it's just a matter of time before someone does have a risk event because of this.
