2012 MINI Countryman — MOT failures & pass rate
The 2012 MINI Countryman passed 85.0% of its 14,841 recorded MOT tests. Small SUVs of a similar age fail 22.3% of the time, so this is 7.3pp better than the group it competes with. Failures cluster in lighting & signalling, tyres and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 9.4% of tests against 5.9% for the next-worst category.
At component level the recurring items are position lamp, headlamp aim and tread depth — position lamp alone was recorded 718 times.
A 150k+ example is materially riskier than a 0-30k one: 20.4% versus 7.7%.
Fuel type barely separates them — petrol fails 14.4% of the time against 15.3% for diesel.
Tyres is the most common advisory, noted on 26.9% of tests — work that passed today but is likely due soon.
The trend is worsening — 12.7% of tests failed in 2021 against 17.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2012 Countryman
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 9.4% of tests. Start there.
- Lighting & signalling (9.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (5.9% 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.
- Brakes (3.2% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
