Aston Martin DBS Known Issues

The DBS shares much with the DB9 but with more brake and tyre load, more heat, and fewer owners willing to use the car hard enough to expose issues early. Consumables and cooling should be watched closely.

Ownership snapshot

A well-used, well-serviced DBS is often a calmer ownership proposition than a static one that has spent years on show. The car does not like neglect disguised as preservation.

Known issues

high Cost: high

Brake wear and judder under fast-road use

Shudder under braking, pulsing pedal, or reduced confidence after a few heavy stops.

Affects: All DBS variants, especially cars driven enthusiastically.
Driveability

Stop hard use immediately if vibration is obvious.

DIY or specialist

Inspection only for most owners; proper correction is specialist work.

Early warning signs

  • Front axle feels busy under motorway-speed braking
  • Pad wear accelerates faster than expected
  • Discs show heavy lipping or surface cracking

Likely root causes

  • Heavy brake load from a fast, heavy GT
  • Fluid not fresh enough for use pattern
  • Pads and discs nearing the end of their useful life

Typical cost context

  • Inspection and fluid service are manageable.
  • Full axle consumables are firmly a high-cost ownership item.

Prevention

  • Inspect brakes before long trips and any spirited road event.
  • Do not stretch fluid intervals.
  • Avoid ignoring a slight pulse that is clearly getting worse.
medium Cost: low

Battery weakness and low-voltage side effects

Stored warnings, poor cranking, or random behaviour in comfort and convenience systems.

Affects: All years, particularly on collector-owned cars.
Driveability

Usually manageable, but repeated poor starts should be fixed promptly.

DIY or specialist

DIY-safe for testing and tender care.

Early warning signs

  • The car needs a tender to stay happy even after use
  • The battery is several years old but still being trusted
  • Starting speed falls off noticeably in colder weather

Likely root causes

  • Old battery
  • Low-use storage pattern
  • Charging or earth connection issues

Typical cost context

  • Battery replacement is cheap insurance compared with chasing false faults.
  • Charging-system diagnosis adds cost but is still minor compared with other DBS jobs.

Prevention

  • Use a tender as standard.
  • Replace weak batteries before winter.
  • Check charging output when the car is serviced.
high Cost: high

Cooling system age-related weakness

Temperature rise in traffic, coolant smell, or signs of staining around cooling components.

Affects: All cars as they age.
Driveability

Stop driving if temperature climbs or coolant loss is obvious.

DIY or specialist

Inspection only. Repairs are specialist territory.

Early warning signs

  • Coolant level changes between services
  • The fan runs frequently in moderate traffic
  • Heat soak seems to affect restart behaviour

Likely root causes

  • Ageing hoses or seals
  • Thermostat and cooling component wear
  • Neglected cooling service history

Typical cost context

  • Preventative hose and thermostat work is far cheaper than an overheating event.
  • Overheating with follow-on engine concerns becomes a major ownership event.

Prevention

  • Treat cooling components as age-related service items.
  • Do not dismiss occasional coolant smell.
  • Inspect the system annually.
medium Cost: medium

Tyre age and rear-axle harshness from neglected driveline mounts

Rear-end clunk, driveline take-up harshness, or a car that feels coarse at low speed.

Affects: More common on older, little-used cars.
Driveability

Usually driveable, but harsh driveline take-up should not be ignored.

DIY or specialist

Inspection is safe; corrective work should be specialist-led.

Early warning signs

  • A small thunk appears when taking up drive
  • The car feels tighter on fresh tyres but still unsettled over broken surfaces
  • Mounts and bushes look original despite age

Likely root causes

  • Driveline mount wear
  • Rear suspension bush age
  • Tyres hardened with age

Typical cost context

  • Diagnosis and selective bush work can be moderate.
  • A wider rear suspension refresh raises the bill.

Prevention

  • Use tyre date codes, not only tread depth, to judge condition.
  • Inspect rear mounts and bushes during annual service.
  • Deal with the first clunk before it becomes the car's 'character'.
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 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 DBS Oil Change GuideAn annual oil service on the DBS is a useful condition check as much as a fluid change. The job is approachable, but use exact workshop data and inspect the car honestly while the underbody is open.

Frequently asked questions

What makes the DBS costlier than a DB9 to keep right?

Mostly the performance envelope. The DBS tends to use tyres, brakes, and sometimes clutches harder, and buyers often pay more to keep cosmetic details correct.

Should buyers be wary of low-mileage DBS cars?

Yes, for the same reason as other older Astons: inactivity can hide weak batteries, stale fluids, and age-related faults.
