Rolls-Royce Dawn MOT Reliability Overview
The Rolls-Royce Dawn is a niche vehicle in the UK, with 2,719 MOT test results recorded in our database spanning 6 manufacture years. It has an overall MOT pass rate of 95.7% and a failure rate of 4.3%, which is well above the UK average of approximately 37%.
Based on this data, the Rolls-Royce Dawn earns a "Excellent" reliability rating. The average Rolls-Royce Dawn presents for MOT with approximately 17,182 miles on the clock. Manufacture year matters: 2021 models achieve the highest pass rate at 100.0%, while 2018 models have the lowest at 92.7%. This 7.3 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Rolls-Royce Dawn is Tyres, affecting 5.9% of all tests. 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. The second most common issue is Identification of the vehicle at 1.4%. Brakes rounds out the top three at 1.0%. 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 Rolls-Royce Dawn ages relatively gracefully. The failure rate increase of 17% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 5 (6.7% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Rolls-Royce Dawn MOT Data
The Rolls-Royce Dawn is a niche vehicle in the UK, with 2,719 MOT test results recorded in our database spanning 6 manufacture years. It has an overall MOT pass rate of 95.7% and a failure rate of 4.3%, which is well above the UK average of approximately 37%.
For Rolls-Royce Dawn owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on tyres and identification of the vehicle 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 Dawn is likely to perform.
Tyres — 5.9% of failures
Tyres issues account for 5.9% of MOT failures on the Rolls-Royce Dawn. 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.
Identification of the vehicle — 1.4% of failures
Identification of the vehicle issues account for 1.4% of MOT failures on the Rolls-Royce Dawn. Identification failures relate to the Vehicle Identification Number (VIN) and registration plate. The VIN must be permanently displayed and legible, and the registration plate must meet British Standard formatting. Typical repair costs: £10–50. Pre-MOT check: Ensure the VIN plate is visible and legible (usually in the windscreen or under the bonnet). Check that number plates are clean, undamaged, and use the correct font and spacing.
Brakes — 1.0% of failures
Brakes issues account for 1.0% of MOT failures on the Rolls-Royce Dawn. 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).
