Top issues to watch for

The most serious Aston Martin Vanquish problems ranked by severity. We track 6 known issues — here are the ones you need to know about first.

Major
Brake hose and line corrosion
MkI, MkII, MkIII2001–20210k–40k miles
MOT data shows brake line corrosion occurring at 3.8 times the fleet average, with the trend worsening. This affects both rigid brake pipes and flexible hoses, with ferrule corrosion being particularly problematic. The Vanquish's aluminium construction may create galvanic corrosion where steel brake components connect. The high-performance braking system operates at elevated pressures, making any line weakness potentially dangerous.
What happens if ignoredCorroded brake lines can burst under pressure, causing complete brake failure without warning. This creates an immediate safety risk. Line replacement requires specialist fitting and system bleeding. Full brake line renewal typically costs £800-1,500 including labour.

Minor
Suspension joint dust cover failure
MkI, MkII, MkIII2001–20210k–40k miles
Ball joint and suspension arm dust covers on the Vanquish deteriorate significantly faster than the fleet average, with MOT data showing failure rates 16.2 times higher than typical cars in the 20-40k mile range. These rubber boots protect the ball joints from dirt and water ingress. The deterioration appears linked to the low-profile suspension design and aggressive wheel alignment settings that stress the joints. Failure to replace torn covers leads to accelerated joint wear and expensive suspension component replacement.
What happens if ignoredTorn dust covers allow water and grit to contaminate the ball joints, causing accelerated wear and play. Failed ball joints create dangerous steering imprecision and can separate completely. Joint replacement costs £200-400 per corner compared to £30-50 for dust cover renewal.

Minor
Steering rack gaiter deterioration
MkI, MkII, MkIII2001–20210k–20k miles
The steering rack gaiter (protective rubber boot covering the steering rack) fails at 14.8 times the fleet average rate, particularly on low-mileage cars under 20,000 miles. This premature failure suggests a design or material issue rather than normal wear. The gaiter protects the steering rack from road dirt and moisture. Aston Martin uses a complex variable-ratio steering system that may stress the gaiter during full lock manoeuvres.
What happens if ignoredFailed gaiters allow dirt and water into the steering rack, causing internal wear and eventual power steering failure. Rack replacement costs £2,000-3,000 compared to £100-200 for gaiter renewal. Steering precision deteriorates before complete failure.

Minor
Parking brake efficiency
MkI, MkII, MkIII2001–202120k–40k miles
Parking brake efficiency drops below MOT requirements at 6 times the fleet average rate in the 20-40k mile range. The Vanquish uses a conventional handbrake system with cables and rear brake integration. Cable stretch, adjuster wear, and rear brake pad contamination from infrequent use contribute to reduced holding force. The heavy weight of the car requires optimal parking brake adjustment to pass MOT efficiency tests.
What happens if ignoredInsufficient handbrake efficiency causes MOT failure and creates a safety risk on slopes. Poor adjustment accelerates cable wear and may damage the rear brake system. Cable replacement and adjustment typically costs £200-400.
