2019 MINI One — MOT failures & pass rate
The 2019 MINI One passed 92.2% of its 6,828 recorded MOT tests. That is 2.1 percentage points better than superminis of a similar age, which fail at 10.0%. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
No single area dominates — tyres (4.3%) and visibility (4.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, brake pads and tread depth — wipers alone was recorded 297 times.
Mileage matters less than usual here: the 2019 One fails 6.2% of the time in the 0-30k band and 6.7% at 90-120k, a spread of only 0.5 points.
Advisories point at the next bill rather than this one: tyres was flagged on 22.7% of tests without failing them.
The trend is improving — the fail rate fell from 10.7% in 2021 to 8.8% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

| 5 | Road wheels | 0.6% | 44 |
| 6 | Suspension | 0.4% | 25 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.

| 0-30k | 4,344 | 6.2% |
| 30-60k | 2,198 | 10.5% |
| 60-90k | 245 | 12.2% |
| 90-120k | 30 | 6.7% |

What to check before buying a 2019 One
On a 2019 One, tyres is what the MOT record says goes wrong most — it appeared in 4.3% of tests. Check these areas before you commit.
- Tyres (4.3% 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.
- Visibility (4.1% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
- Brakes (1.8% 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.
