Aston Martin Vanquish Known Issues

The second-generation Vanquish is generally robust when used and maintained properly, but it carries the familiar Aston warnings around low voltage, consumables, and age-related chassis wear.

  • 4 issues documented
  • 2 high or major severity

Ownership snapshot

Because many Vanquish cars are cherished, low use can create almost as many problems as hard use. The sweet spot is careful, regular exercise with a strong maintenance file behind it.

Known issues

medium Cost: low

Battery sensitivity and wake-up faults

Slow starts, warning messages at startup, or inconsistent comfort-system behaviour.

Affects: All years, especially low-use examples.
Driveability

Usually manageable, but do not keep chasing random faults until voltage is confirmed healthy.

DIY or specialist

DIY-safe for battery testing and tender use.

Early warning signs

  • The car behaves better after a long drive than after standing
  • Voltage-related warnings appear on cold mornings
  • Battery history is vague or undocumented

Likely root causes

  • Battery aging
  • Insufficient tender use
  • Repeated short-start cycles

Typical cost context

  • Battery replacement is relatively minor.
  • Allowing low voltage to trigger repeated warnings creates a more time-consuming diagnostic path.

Prevention

  • Treat the tender as standard equipment.
  • Replace aging batteries before failure.
  • Scan the car if warning patterns begin to stack.
high Cost: high

Brake judder and consumable bills

Pulsing under braking, steering shake, or simply very short consumable life if the car is used enthusiastically.

Affects: All variants, especially cars driven hard or stored after being washed with wet brakes.
Driveability

Do not keep using the car hard if judder is increasing.

DIY or specialist

Inspection only unless you are already experienced with performance brake work.

Early warning signs

  • A small pulse is present before a full shake develops
  • Pad thickness drops faster than expected
  • Disc surfaces show pronounced corrosion or uneven colour

Likely root causes

  • Uneven pad deposits or heat load
  • Aged fluid
  • Heavy car, high speed, and infrequent but intense use

Typical cost context

  • Inspection is minor.
  • Axle sets of premium pads and discs are a high-cost ownership item.

Prevention

  • Inspect brakes well before long trips.
  • Keep fluid fresh.
  • Avoid leaving the car parked for long periods with heavily corroded disc faces.
medium Cost: medium

Rear-end clunks from driveline or suspension wear

A noticeable thunk when taking up drive or a low-speed rear knock over broken surfaces.

Affects: More common on older cars or those with original bushes and mounts.
Driveability

Usually driveable, but a worsening clunk should be diagnosed before it affects tyre wear and confidence.

DIY or specialist

Inspection is safe; repair and geometry work should be specialist-led.

Early warning signs

  • A faint clunk is audible before it becomes obvious
  • The rear axle feels less composed over quick surface changes
  • Tyre age and bush age are both unknown

Likely root causes

  • Driveline mount wear
  • Suspension bush deterioration
  • Alignment and tyre issues making the rear axle feel worse

Typical cost context

  • Selective bushing or mount work may be moderate.
  • A wider rear axle refresh becomes more expensive once several parts are due together.

Prevention

  • Inspect bushes and mounts annually.
  • Replace old tyres even if tread is present.
  • Do not dismiss a driveline knock as normal halo-car behaviour.
high Cost: high

Cooling and hot-running complaints

Temperature rise in traffic, fan overactivity, or signs of coolant smell after a hot run.

Affects: All years as components age.
Driveability

Stop driving if temperature climbs abnormally or coolant loss is apparent.

DIY or specialist

Inspection only.

Early warning signs

  • Coolant level changes between checks
  • Traffic driving makes the gauge more active than expected
  • Restart quality changes after a hot stop

Likely root causes

  • Cooling component wear
  • Ageing hoses or seals
  • Neglected coolant service

Typical cost context

  • Preventative cooling work is sensible and usually cheaper than waiting.
  • Any overheating event is potentially a major bill.

Prevention

  • Monitor coolant level and smell closely.
  • Refresh ageing components before failure.
  • Avoid delaying investigation just because the issue only appears in traffic.
Aston Martin Battery Replacement and Tender SetupBattery care is one of the most useful ownership skills on any modern Aston Martin. Whether you are replacing the battery or simply setting up a tender routine, the goal is stable voltage and fewer false faults.Aston Martin Battery Drain and Flat Battery DiagnosisRepeated flat batteries on an Aston Martin are often caused by a tired battery or low-use pattern rather than a dramatic parasitic drain. Start by proving the battery and charging system before hunting for obscure faults.Aston Martin Brake Pads and Disc InspectionRegular brake inspection is one of the simplest ways to prevent expensive Aston Martin running-cost surprises. This guide focuses on safe visual checks, wear patterns, and when inspection should turn into a specialist visit.Aston Martin Brake Fluid ChangeBrake fluid age matters on every Aston Martin, and especially on the heavier or faster models. A fluid change is simple in principle, but it should only be attempted if you can guarantee a clean process and a firm pedal afterwards.Aston Martin Vibration Under BrakingSteering shake or pedal pulse under braking is usually a brake-condition problem before it is a mysterious chassis issue. The question is whether the root cause is deposits, wear, heat, or suspension support.Aston Martin Rear Axle or Driveline Clunk DiagnosisRear-end clunks on Aston Martin cars are usually mount, bush, or driveline take-up issues rather than something instantly catastrophic. Even so, the noise should be diagnosed before tyre wear and drivability degrade.

Frequently asked questions

Is the Vanquish mostly about cosmetic upkeep?

Cosmetic upkeep matters because parts are expensive, but the real ownership foundation is still battery health, brakes, tyres, cooling, and suspension condition.

Should buyers be wary of a Vanquish that has barely been driven?

Yes. Static ownership can hide exactly the kind of low-voltage, seal, and consumable ageing problems that later become frustrating.
