2001 Toyota Corolla — MOT failures & pass rate
Across 15,214 MOT tests, the 2001 Toyota Corolla recorded a 76.8% pass rate. Small family cars of a similar age fail 27.9% of the time, so this is 4.6pp better than the group it competes with. Failures cluster in lighting & signalling, brakes and suspension.
What the MOT record shows
No single area dominates — lighting & signalling (12.3%) and brakes (11.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, position lamp and component mounting prescribed areas — service brake performance alone was recorded 1,106 times.
Condition tracks the odometer closely. Failures run at 9.3% in the 0-30k band and 31.4% in the 150k+ band, a 22.2-point spread — more than double.
Advisories point at the next bill rather than this one: brakes was flagged on 29.9% 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 | Brakes | 29.9% | 4,557 |
| 2 | Tyres | 27.2% | 4,145 |

| 5 | Emissions & environmental | 14.8% | 2,254 |
| 6 | Body, structure & corrosion | 11.7% | 1,776 |
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 | 270 | 9.3% |
| 30-60k | 2,387 | 17.7% |
| 60-90k | 4,475 | 21.3% |
| 90-120k | 4,623 | 24.3% |
| 120-150k | 2,285 | 28.2% |
| 150k+ | 1,158 | 31.4% |

What to check before buying a 2001 Corolla
On a 2001 Corolla, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.3% of tests. Check these areas before you commit.
- Lighting & signalling (12.3% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (11.2% 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.
- Suspension (6.4% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
