All Known Issues

Electronic Control Module Glitches

ModerateElectrics & Electronics

With dozens of ECUs, the Phantom VIII is highly sensitive to voltage drops. Low battery health can cause false failures for the rear-axle steering or active anti-roll bars.

Est. Repair Cost: £500–£2,000
Warning Signs:

Chassis control warnings, Infotainment lag, Soft-close or power-door inconsistency

What to Inspect:
  • Check battery health and manufacture date
  • Scan for stored voltage-related codes
  • Test power-closing door functionality repeatedly

Air Strut and Active Roll Bar Noise

ModerateSuspension & Chassis

The complex active chassis components can develop minor knocks or squeaks if the car is driven frequently on poor UK roads.

Est. Repair Cost: £2,000–£4,000
Warning Signs:

Faint knocking over speed bumps, Hydraulic noise from active roll bars, Ride height calibration messages

What to Inspect:
  • Listen for suspension noise in "Comfort" mode
  • Check for any visible seepage from active roll bar actuators

Starlight Headliner Fiber Breakage

MinorInterior & Trim

The iconic Starlight headliner uses fibre-optic strands to create a starry sky effect. Over time, individual fibres can break or go dark, creating visible gaps in the star pattern. Complete headliner replacement is the only true fix.

Est. Repair Cost: £3,000–£8,000
Warning Signs:

Dark spots or gaps in the starlight pattern, Individual fibres no longer illuminating, Uneven star brightness across the headliner

What to Inspect:
  • Inspect the headliner with the stars illuminated in a dark environment
  • Check for any visible fibre breakage or dark patches
  • Ask if any fibre repairs have been carried out
