All Known Issues

Suspension Component Corrosion

SeriousSuspension & Chassis

The second-generation Vantage shows exceptionally high rates of suspension component corrosion, particularly on control arms, wishbones and suspension mounting points. The issue appears related to inadequate corrosion protection during manufacture rather than age-related wear, with failures documented on cars under 20,000 miles. Corroded suspension components present a direct safety risk and can fail catastrophically.

Est. Repair Cost: £800–£3,500
Warning Signs:

Knocks or creaks from the suspension over bumps, Uneven tyre wear or handling changes, MOT failure on suspension corrosion or excessive play

What to Inspect:
  • Inspect suspension arms and mounting points for surface or structural corrosion
  • Check MOT history for repeated suspension advisories
  • Have the car inspected on a ramp by an Aston Martin specialist
  • Listen for unusual suspension noises during the test drive

Brake Pipe and Hose Corrosion

SeriousBrakes

Aston Martin Vantages are known to suffer from brake pipe and hose corrosion, particularly where lines run along the underside exposed to road salt and moisture. The metal ferrules connecting flexible brake hoses to hard lines can corrode, leading to brake fluid leakage and potential brake system failure.

Est. Repair Cost: £300–£1,200
Warning Signs:

Brake fluid level dropping without visible external leak, Corrosion visible on brake pipes or hose connections, MOT advisory or failure on brake corrosion, Spongy or reduced brake pedal feel

What to Inspect:
  • Inspect brake pipes along the underside for corrosion or surface rust
  • Check brake hose ferrules for corrosion at connection points
  • Look for brake fluid residue near wheels or on the underside
  • Review MOT history for brake-related advisories

Engine Management and Coil Pack Faults

ModerateEngine

The Mercedes-AMG M177 twin-turbo V8 engine can suffer from coil pack degradation and lambda sensor failures, causing the engine management light to illuminate. This is particularly common on lower-mileage examples and can relate to fuel quality sensitivity. Ignoring these faults can lead to catalyst damage and reduced fuel economy.

Est. Repair Cost: £200–£800
Warning Signs:

Engine management light illuminated on the instrument cluster, Rough idle or misfiring under load, Reduced engine performance or fuel economy, Stored fault codes related to ignition or sensors

What to Inspect:
  • Scan for stored engine management fault codes
  • Check if coil packs or lambda sensors have been replaced
  • Listen for rough idle or misfire when the engine is warm
  • Ask about fuel quality used by previous owners
