Aston Martin Dbs MOT Reliability Overview
The Aston Martin Dbs is a relatively common sight on UK roads, with 13,689 MOT test results recorded in our database spanning 15 manufacture years. It has an overall MOT pass rate of 91.5% and a failure rate of 8.5%, which is well above the UK average of approximately 37%.
Based on this data, the Aston Martin Dbs earns a "Excellent" reliability rating. The average Aston Martin Dbs presents for MOT with approximately 21,918 miles on the clock. Manufacture year matters: 2021 models achieve the highest pass rate at 99.7%, while 1970 models have the lowest at 76.6%. This 23.1 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Aston Martin Dbs is Lamps, Reflectors and Electrical Equipment, affecting 4.8% of all tests. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. The second most common issue is Tyres at 4.4%. Brakes rounds out the top three at 3.1%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?
The Aston Martin Dbs shows a moderate increase in MOT failures after warranty. The 24% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 7 (11.9% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Aston Martin Dbs MOT Data
The Aston Martin Dbs is a relatively common sight on UK roads, with 13,689 MOT test results recorded in our database spanning 15 manufacture years. It has an overall MOT pass rate of 91.5% and a failure rate of 8.5%, which is well above the UK average of approximately 37%.
For Aston Martin Dbs owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on lamps, reflectors and electrical equipment and tyres for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Dbs is likely to perform.
Lamps, Reflectors and Electrical Equipment — 4.8% of failures
Lamps, Reflectors and Electrical Equipment issues account for 4.8% of MOT failures on the Aston Martin Dbs. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Tyres — 4.4% of failures
Tyres issues account for 4.4% of MOT failures on the Aston Martin Dbs. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Brakes — 3.1% of failures
Brakes issues account for 3.1% of MOT failures on the Aston Martin Dbs. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).
