The complex folding roof uses numerous sensors to ensure alignment. Dirt or slight misalignment can cause the cycle to pause or fail.

Est. Repair Cost: £800–£2,500
Warning Signs:

Roof stops mid-cycle, Warning message for "Roof Not Latched", Increased wind noise at speed

What to Inspect:

Battery Drain and Electrical Gremlins

ModerateElectrics & Electronics

The Dawn, like other modern Rolls-Royces, is highly sensitive to battery voltage. Cars that sit unused for extended periods can develop multiple warning lights, infotainment glitches, and power-door inconsistencies due to low battery voltage.

Est. Repair Cost: £350–£1,200
Warning Signs:

Multiple dashboard warnings after startup, Infotainment screen lag or freezes, Soft-close or power-door malfunction, Slow cranking on startup

What to Inspect:
  • Check battery age and voltage
  • Ensure the car has been kept on a battery conditioner
  • Start the car from cold after storage and observe warning lights
