2020 Toyota Aygo — MOT failures & pass rate
The 2020 Toyota Aygo passed 93.6% of its 53,747 recorded MOT tests. That is 1.3 percentage points better than city cars of a similar age, which fail at 7.6%. Failures cluster in tyres, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — tyres (3.3%) and lighting & signalling (2.8%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are wipers, headlamp aim and stop lamp — wipers alone was recorded 801 times.
A 90-120k example is materially riskier than a 0-30k one: 10.1% versus 5.3%.
Tyres is the most common advisory, noted on 19.0% of tests — work that passed today but is likely due soon.
The trend is worsening — 4.7% of tests failed in 2021 against 8.2% 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 |

| 5 | Visibility | 2.2% | 1,201 |
| 6 | Road wheels | 1.4% | 748 |
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 | 42,281 | 5.3% |
| 30-60k | 10,616 | 9.8% |
| 60-90k | 752 | 15.4% |
| 90-120k | 69 | 10.1% |
Failure rate by age
Trend over time

What to check before buying a 2020 Aygo
The failure pattern for this year is specific enough to inspect against: tyres accounted for 3.3% of tests. Start there.
- Tyres (3.3% 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.
- Lighting & signalling (2.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Visibility (2.4% 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.
