2001 Toyota Yaris — MOT failures & pass rate
Across 54,931 MOT tests, the 2001 Toyota Yaris recorded a 73.0% pass rate. Superminis of a similar age fail 29.4% of the time, so this is 2.5pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (17.5%) and suspension (15.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, headlamp aim and headlamp — component mounting prescribed areas alone was recorded 5,054 times.
Mileage is the strongest signal on the record: 14.6% of 0-30k cars fail, rising to 32.9% once past 150k — 2.3× the risk.
Advisories point at the next bill rather than this one: suspension was flagged on 49.0% of tests without failing them.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 49.0% | 26,940 |
| 2 | Tyres | 26.5% | 14,532 |
| 3 | Lighting & signalling | 23.4% | 12,865 |

| 5 | Body, structure & corrosion | 18.9% | 10,369 |
| 6 | Other defects | 16.7% | 9,194 |
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 | 857 | 14.6% |
| 30-60k | 8,016 | 19.8% |
| 60-90k | 16,504 | 25.1% |

| 120-150k | 9,117 | 31.1% |
| 150k+ | 4,567 | 32.9% |

What to check before buying a 2001 Yaris
On a 2001 Yaris, lighting & signalling is what the MOT record says goes wrong most — it appeared in 17.5% of tests. Check these areas before you commit.
- Lighting & signalling (17.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (15.0% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Visibility (7.0% 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.
