2014 Toyota Aygo — MOT failures & pass rate
The 2014 Toyota Aygo passed 85.4% of its 112,471 recorded MOT tests. That is 2.8 percentage points better than city cars of a similar age, which fail at 17.4%. Failures cluster in lighting & signalling, brakes and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (7.0%) and brakes (6.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, service brake performance and tread depth — headlamp aim alone was recorded 3,673 times.
Condition tracks the odometer closely. Failures run at 9.0% in the 0-30k band and 28.6% in the 150k+ band, a 19.6-point spread — more than double.
Advisories point at the next bill rather than this one: tyres was flagged on 25.6% of tests without failing them.
The trend is worsening — 12.0% of tests failed in 2021 against 17.2% 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 | 25.6% | 28,813 |
| 2 | Brakes | 22.4% | 25,203 |
| 3 | Suspension | 17.7% | 19,869 |

| 5 | Lighting & signalling | 3.8% | 4,259 |
| 6 | Body, structure & corrosion | 3.2% | 3,578 |
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 | 20,469 | 9.0% |
| 30-60k | 54,433 | 13.2% |
| 60-90k | 29,147 | 18.4% |

| 120-150k | 1,235 | 24.4% |
| 150k+ | 363 | 28.6% |
Failure rate by age
Trend over time

What to check before buying a 2014 Aygo
On a 2014 Aygo, lighting & signalling is what the MOT record says goes wrong most — it appeared in 7.0% of tests. Check these areas before you commit.
- Lighting & signalling (7.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (6.1% 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 (5.1% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
