Historical MOT pass rates and DVLA records for 2021 model year cars.
- High Voltage Battery Junction Box (HVBJB) FailureSerious
The main high-voltage contactors can overheat and weld shut or stick open, especially after rapid acceleration or DC fast charging. This results in a sudden loss of motive power.
- Charging System Faults and 12V Battery IssuesModerate
The Mach-E relies on a small 12V auxiliary battery to power the charging contactors and control modules. If the 12V drops below 11.5V, charging will not start even though the main battery is full. Charge port actuator failures and onboard charger faults also cause charging to fail or stop mid-session.
