Based on this data, the Mini Mini earns a "Good" reliability rating. The average Mini Mini presents for MOT with approximately 66,026 miles on the clock. Manufacture year matters: 2017 models achieve the highest pass rate at 89.0%, while 2001 models have the lowest at 46.3%. This 42.7 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Mini Mini is Brakes, affecting 32.1% of all tests. 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. The second most common issue is Tyres at 20.2%. Suspension rounds out the top three at 18.1%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

📉 How Age Affects Reliability
MOT failure rate by vehicle age for the Mini Mini. The dashed red line marks when the manufacturer warranty typically expires (3 years).
Line chart showing MOT failure rate by vehicle age from 3 to 20 years, with warranty expiry marked at 3 years.
💡 What does the warranty cliff mean?
The Mini Mini ages relatively gracefully. The failure rate increase of 9% after warranty is below average, suggesting good long-term reliability. Peak failure occurs at age 18 (46.7% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.
* High Fail Rate badge indicates an MOT pass rate below 65% (failure rate above 35%).

About Mini Mini MOT Data
The Mini Mini is one of the most widely tested vehicles in the UK, with 5,061,815 MOT test results recorded in our database spanning 35 manufacture years. It has an overall MOT pass rate of 66.1% and a failure rate of 33.9%, which is slightly above the UK average of approximately 37%.
For Mini Mini owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on brakes 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 Mini is likely to perform.
Brakes — 32.1% of failures
Brakes issues account for 32.1% of MOT failures on the Mini Mini. 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).
Tyres — 20.2% of failures
Tyres issues account for 20.2% of MOT failures on the Mini Mini. 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.
Suspension — 18.1% of failures
Suspension issues account for 18.1% of MOT failures on the Mini Mini. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
