What Aston Martin cars fail on
The items most often behind a first-test failure across Aston Martin model groups, as a share of Aston Martin tests. DVSA publishes each model group's six most common categories, so this ranks the biggest published causes rather than every possible one.
- Exhaust Emissions — 1.3% of Aston Martin tests. The car exceeded its emissions limits. Can be a sensor or a service, but on a diesel it can also mean an expensive filter or catalyst.
- Headlamp Aim — 1.2% of Aston Martin tests. Headlights pointing too high or low. Cheap to adjust, and common on every make.
- Condition — 1.1% of Aston Martin tests. Corrosion, damage or wear on a tested component. Worth seeing in person, as the cost ranges from trivial to structural.
- Position Lamps — 0.7% of Aston Martin tests. A side or tail light out. Usually a bulb.
- Washers — 0.5% of Aston Martin tests. Empty or blocked washers. Trivial, but again a sign of the last owner's care.
- Brake Performance — 0.4% of Aston Martin tests. The brakes underperformed on the rolling road. Expect brake work rather than an adjustment.
- Springs — 0.4% of Aston Martin tests. A broken or sagging coil spring. Replaced in pairs, so it is not the cheapest failure.
- Wipers — 0.3% of Aston Martin tests. Worn wiper blades. Minutes to fix, and a fair hint that servicing was skipped.
