2017 Toyota Aygo — MOT failures & pass rate
Across 117,219 MOT tests, the 2017 Toyota Aygo recorded a 91.1% pass rate. City cars of a similar age fail 11.7% of the time, so this is 2.7pp better than the group it competes with. Failures cluster in tyres, visibility and brakes.
What the MOT record shows
No single area dominates — tyres (4.2%) and visibility (3.7%) 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 brake pads — wipers alone was recorded 3,034 times.
Condition tracks the odometer closely. Failures run at 6.3% in the 0-30k band and 23.9% in the 150k+ band, a 17.6-point spread — more than double.
Tyres is the most common advisory, noted on 24.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 6.6% of tests failed in 2021 against 10.8% 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.

| 6 | Road wheels | 1.8% | 2,154 |
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 | 57,142 | 6.3% |
| 30-60k | 48,691 | 10.5% |
| 60-90k | 9,684 | 14.5% |

| 120-150k | 226 | 24.3% |
| 150k+ | 67 | 23.9% |

What to check before buying a 2017 Aygo
The failure pattern for this year is specific enough to inspect against: tyres accounted for 4.2% of tests. Start there.
- Tyres (4.2% 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 (3.7% 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 (3.3% 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.
