2011 MINI John Cooper Works — MOT failures & pass rate
The 2011 MINI John Cooper Works passed 85.4% of its 673 recorded MOT tests. Superminis of a similar age fail 23.9% of the time, so this is 9.4pp better than the group it competes with. Failures cluster in lighting & signalling, tyres and emissions & environmental.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 11.4% of tests against 4.6% for the next-worst category.
At component level the recurring items are position lamp, headlamp aim and catalyst emissions — position lamp alone was recorded 48 times.
A 90-120k example is materially riskier than a 0-30k one: 21.5% versus 8.8%.
Tyres is the most common advisory, noted on 21.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 13.1% of tests failed in 2021 against 15.1% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Tyres | 21.4% | 144 |
| 2 | Brakes | 18.9% | 127 |

| 5 | Lighting & signalling | 7.1% | 48 |
| 6 | Other defects | 5.9% | 40 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 68 | 8.8% |
| 30-60k | 187 | 11.8% |
| 60-90k | 316 | 15.5% |
| 90-120k | 93 | 21.5% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 2011 John Cooper Works
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 11.4% of tests. Start there.
- Lighting & signalling (11.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (4.6% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
- Emissions & environmental (3.6% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
