Most Common Aston Martin One-77 Faults & Repair Costs
Carbon Fibre Monocoque and Body Panel Damage
The One-77's full carbon-fibre construction means any impact damage, even minor, can be catastrophically expensive to repair. Unlike aluminium, carbon fibre cannot be pulled or easily patched, and panels are one-off items.
Hairline cracks in paintwork, Visible weave pattern through paint, Wind noise or water ingress around panels
- Have the car inspected by an Aston Martin carbon-fibre specialist
- Check all panels for signs of impact, repair, or poor respray
- Inspect mounting points for stress cracks
V12 Engine Management and Sensor Faults
The 7.3-litre V12 uses complex engine management systems that can develop sensor faults, causing intermittent misfires, reduced power, or limp mode. Due to the car's rarity, diagnostics require specialist Aston Martin equipment.
Intermittent misfires, Check Engine Light, Reduced power or limp mode, Rough idle
- Scan for fault codes using Aston Martin-specific diagnostic tools
- Check for any history of engine management work
- Test the car through the full rev range for smooth operation
