2001 Subaru Impreza — MOT failures & pass rate
Across 5,801 MOT tests, the 2001 Subaru Impreza recorded a 78.3% pass rate. That is 6.2 percentage points better than small family cars of a similar age, which fail at 27.8%. Failures cluster in lighting & signalling, suspension and emissions & environmental.
What the MOT record shows
No single area dominates — lighting & signalling (12.5%) and suspension (10.8%) 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, catalyst emissions and headlamp aim — component mounting prescribed areas alone was recorded 540 times.
Condition tracks the odometer closely. Failures run at 8.1% in the 0-30k band and 26.7% in the 150k+ band, a 18.7-point spread — more than double.
Advisories point at the next bill rather than this one: suspension was flagged on 27.8% of tests without failing them.
The trend is improving — the fail rate fell from 23.4% in 2021 to 20.1% in 2025, as the worst-kept examples leave the fleet.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |

| 5 | Lighting & signalling | 10.3% | 597 |
| 6 | Emissions & environmental | 8.1% | 467 |
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 | 62 | 8.1% |
| 30-60k | 355 | 11.3% |
| 60-90k | 1,129 | 17.4% |

What to check before buying a 2001 Impreza
On a 2001 Impreza, lighting & signalling is what the MOT record says goes wrong most — it appeared in 12.5% of tests. Check these areas before you commit.
- Lighting & signalling (12.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (10.8% 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.
- Emissions & environmental (8.6% of tests): More common on older diesels (DPF/EGR) — can be expensive; check for warning lights and smoke. Typical repair: £100–£600.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
