All Known Issues

High Voltage Battery Junction Box (HVBJB) Failure

SeriousElectrics & Electronics

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.

Est. Repair Cost: £0 (Under Warranty/Recall)
Warning Signs:

"Stop Safely Now" message, Total loss of drive, Car refuses to charge

What to Inspect:
  • Verify with a Ford dealer if the HVBJB recall campaign has been completed for that specific VIN

Charging System Faults and 12V Battery Issues

ModerateElectrics & Electronics

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.

Est. Repair Cost: £60-£500
Warning Signs:

Unable to charge or Charging fault message, Charge port door will not open, Charging stops mid-session, 12V battery low warning

What to Inspect:
  • Check 12V battery health and age
  • Test charge port door operation
  • Verify FordPass app connectivity
  • Try charging at a public and home charger

Software and SYNC 4A Infotainment Glitches

MinorElectrics & Electronics

The 15.5-inch touchscreen may freeze, go blank or lag badly, temporarily knocking out climate control and drive-mode controls. Apple CarPlay audio can cut out, rearview cameras can freeze and driver-assistance features can temporarily go offline.

Est. Repair Cost: £0-£400
Warning Signs:

Frozen or black central screen, Apple CarPlay audio cutting out, Rearview camera freezing, Driver-assistance messages disappearing

What to Inspect:
  • Run navigation, audio and phone pairing during the drive
  • Check current software version
  • Ask if OTA updates have been applied successfully

Build Quality and Wind Noise

MinorBodywork & Rust

Early Mach-E builds drew criticism for inconsistent panel gaps, wind noise around mirrors and A-pillars at highway speeds, paint imperfections and interior creaks and rattles. By 2024 Ford factory processes had improved but these issues still show up in the used pool.

Est. Repair Cost: £0-£500
Warning Signs:

Wind noise around mirrors or A-pillars at speed, Creaky dashboard or buzzing door panels, Uneven panel gaps or paint imperfections, Hatch-area rattles over rough roads

What to Inspect:
  • Inspect panel gaps and paint condition
  • Listen for wind noise on a motorway test drive
  • Check for signs of windshield reinstallation

Buying Tips for 2022 Ford Mustang Mach-E

  • Crucially, check if the High Voltage Battery Junction Box (HVBJB) recall has been completed; failure of this part will cause the car to lose motive power.
  • Test the massive SYNC 4A central touchscreen for lag or freezing, and ensure the car is receiving OTA (Over-The-Air) software updates.
  • Verify the Phone As A Key (PAAK) functionality works reliably, as early cars struggled with Bluetooth connectivity issues.
  • Check the operation of the electronic push-button door handles (E-Latch) to ensure they open cleanly, particularly in cold weather.
  • Listen for any clunking from the suspension over rough roads; some owners report noisy dampers or anti-roll bar bushes.
  • Inspect the glass panoramic roof (if fitted) to ensure it is properly sealed, as early US-built models had recalls for improperly bonded glass.
