In owners’ own words

Source: NHTSA complaint database

Filed with NHTSA by the people who own these cars, about the electrical system. Quoted as written, with anything identifying removed; unverified reports — what was said, not a finding that it was true.

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.

On 4/1, while entering the FWY @ about 50 mph under moderate accel, big thump (felt like the trans fell out), drivers display cycled thru multiple errors with "stop safely now" repeatedly flashing. Throttle went dead, speed dropped to 35 and steadily decreased.

Electrical System Apr 11, 2022 NHTSA owner report

The 12V battery drains to the point the car will not boot or go in gear. It spits about 8 error messages at you but none that say low 12V battery. This has now happened 3 times in the last year. This has left me stranded in the cold hundreds of miles from home one of those times.
