Aston Martin DB12 Known Issues

The DB12 is a very new model with a limited ownership track record. The issues identified so far relate to infotainment software maturity, the oil-consumption characteristic of the high-output M177 V8, brake wear given the car's weight, and battery sensitivity common to all modern Astons.

  • 4 issues documented
  • All low to medium severity
  • Independent ownership view

Ownership snapshot

DB12 owners at this stage are advised to stay close to the dealer for OTA updates, monitor oil level more actively than the service interval implies, and set up a tender routine as a day-one ownership habit.

Known issues

low Cost: low

Infotainment software bugs and OTA update dependency

Occasional screen freezes, connectivity drops, or unexpected app behaviour in the new infotainment system.

Affects: All 2023-present DB12 variants.
Driveability

No effect on driving safety or vehicle operation.

DIY or specialist

Not a DIY item. Report issues to the dealer and track software versions.

Early warning signs

  • The system requires a restart to restore full function
  • Android Auto or Apple CarPlay drops the connection mid-journey
  • Some menus or settings revert unexpectedly after a software update

Likely root causes

  • The DB12 is the first Aston with this level of smartphone integration and associated software complexity
  • Early software versions on any new system typically need iterative updates
  • OTA update success depends on connectivity and battery voltage at update time

Typical cost context

  • OTA and dealer software updates are covered under warranty.
  • Hardware-level issues on a new car are also a warranty matter.

Prevention

  • Keep the car on the latest available software version.
  • Ensure the battery is healthy before OTA updates begin.
  • Report recurring glitches under warranty rather than accepting them.
medium Cost: low

Oil consumption from the high-output M177 V8

Oil level drops between services at a rate owners may not anticipate if they are used to less highly tuned engines.

Affects: All 2023-present DB12 variants with the 680 PS AMG M177 V8.
Driveability

Safe to drive with oil above minimum. Do not continue driving if the level is at or below the minimum mark.

DIY or specialist

Oil checking and top-ups are a standard owner task. Persistent high consumption needs specialist attention.

Early warning signs

  • Level is noticeably below max well before the next service interval
  • Faint blue smoke on a cold start that disappears quickly
  • A mild oil smell from the engine bay after a longer run

Likely root causes

  • The 680 PS version of the M177 is a high-stress tune of a block already known to consume some oil
  • Grand touring use at sustained higher speeds increases consumption
  • The service interval does not adequately account for consumption in all use patterns

Typical cost context

  • Oil top-ups are inexpensive if managed proactively.
  • Engine damage from low oil on a high-output turbocharged V8 is not.

Prevention

  • Check oil level every 1,000 miles regardless of service reminder status.
  • Keep a small supply of the correct approved oil available.
  • Log consumption and raise any significant increase with the dealer.
medium Cost: medium

Accelerated brake wear from vehicle weight and performance

Brake pads and discs wearing more quickly than expected given service intervals, particularly on cars used with enthusiasm.

Affects: All 2023-present DB12 variants; 1,685 kg kerb weight with 680 PS.
Driveability

Monitor brake feel carefully. Do not continue to drive with worn pads that are generating heat or noise beyond the expected level.

DIY or specialist

Brake inspection is appropriate for an experienced owner. Replacement on a new high-value car is better done by a specialist.

Early warning signs

  • Brake pad warning light activates sooner than the previous service interval suggested
  • A light squeal or pulse under moderate braking that was not present before
  • Visual inspection shows pad wear beyond what the mileage implies

Likely root causes

  • A 1,685 kg car at performance speeds generates significant braking energy
  • Spirited driving, repeated hard stops, and motorway-speed braking wear hardware quickly
  • Factory-fit brake specification is a balance of everyday refinement and performance

Typical cost context

  • A full brake service on the DB12 is a medium-to-high cost job given the size and specification.
  • Delaying beyond warning-light activation can damage disc faces and increase total cost.

Prevention

  • Check pad thickness at every oil service, not only when the warning light activates.
  • Budget for brake wear as a routine consumable cost rather than an unexpected one.
  • Use quality replacement parts and avoid cheap substitutes on an expensive car.
medium Cost: low

Battery drain if the car is stored or used infrequently

Flat or low battery after a few days without use, leading to startup faults or warning lights.

Affects: All 2023-present DB12 variants.
Driveability

Safe once the battery is healthy. Do not ignore repeated low-voltage symptoms.

DIY or specialist

Tender use and basic voltage checks are owner-appropriate from day one.

Early warning signs

  • Slow cranking after a short period parked
  • Warning lights on startup that clear after a drive
  • Infotainment or convenience features behave erratically

Likely root causes

  • Modern high-electronics platform maintains a notable standing draw
  • Short-trip use and infrequent driving do not maintain battery charge
  • The same characteristic present across the modern Aston lineup

Typical cost context

  • A quality tender is a small upfront cost with a large ownership benefit.
  • Repeated deep discharge shortens battery life and may cause software reset events.

Prevention

  • Connect a tender whenever the car is parked for more than a few days.
  • Do not rely on dealer or garage storage without confirming a tender is connected.
  • Set up the tender connection point properly so the habit is easy to maintain.
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 Check Engine and Emissions Fault DiagnosisA check engine light on an Aston Martin can mean anything from a minor sensor complaint to a drivability issue that should not be ignored. The smart move is to read the codes, then interpret them in the context of voltage, service history, and how the car is being used.Aston Martin DB12 Oil Change GuideThe DB12 uses a 680 PS version of the AMG M177 V8 — the highest-output application at launch. The oil service is a core ownership task that also serves as an inspection opportunity for the car's underbody, cooling, and brake condition.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 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 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.

Frequently asked questions

Are there major reliability concerns with the DB12 so far?

Nothing fundamental has emerged, but the car is too new for a complete picture. Infotainment software, oil consumption, and battery sensitivity are the current watch points.

Does the DB12 have Android Auto and Apple CarPlay?

Yes, it is the first DB-series Aston to offer both as standard. The system is early-generation and subject to ongoing OTA improvement.
