2015 Toyota Aygo — MOT failures & pass rate
130,322 MOT tests on the 2015 Toyota Aygo are in this dataset, and 88.4% of them passed. City cars of a similar age fail 15.6% of the time, so this is 3.9pp better than the group it competes with. Failures cluster in brakes, tyres and visibility.
What the MOT record shows
No single area dominates — brakes (5.4%) and tyres (5.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, tread depth and headlamp aim — wipers alone was recorded 3,107 times.
Mileage is the strongest signal on the record: 7.8% of 0-30k cars fail, rising to 25.7% once past 150k — 3.3× the risk.
Tyres is the most common advisory, noted on 26.0% of tests — work that passed today but is likely due soon.
The trend is worsening — 9.6% of tests failed in 2021 against 13.6% 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 | 26.0% | 33,826 |
| 2 | Brakes | 20.4% | 26,589 |

| 6 | Lighting & signalling | 2.5% | 3,233 |
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 | 34,044 | 7.8% |
| 30-60k | 65,609 | 11.1% |

| 120-150k | 902 | 21.5% |
| 150k+ | 292 | 25.7% |
Failure rate by age

What to check before buying a 2015 Aygo
The failure pattern for this year is specific enough to inspect against: brakes accounted for 5.4% of tests. Start there.
- Brakes (5.4% 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.
- Tyres (5.0% 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 (3.6% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
