2003 Toyota Hiace — MOT failures & pass rate
Across 4,550 MOT tests, the 2003 Toyota Hiace recorded a 74.6% pass rate. All cars of a similar age fail 27.7% of the time, so this is 2.2pp better than the group it competes with. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (14.8%) and suspension (14.1%) 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, integral vehicle structure condition and chassis condition — component mounting prescribed areas alone was recorded 750 times.
Mileage is the strongest signal on the record: 16.7% of 30-60k cars fail, rising to 27.5% once past 150k.
Advisories point at the next bill rather than this one: suspension was flagged on 43.4% of tests without failing them.
The trend is worsening — 24.9% of tests failed in 2021 against 26.8% 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.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 43.4% | 1,976 |
| 2 | Brakes | 28.8% | 1,309 |
| 3 | Tyres | 21.3% | 968 |

| 5 | Lighting & signalling | 15.5% | 707 |
| 6 | Other defects | 15.3% | 696 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 30-60k | 120 | 16.7% |
| 60-90k | 399 | 20.3% |
| 90-120k | 694 | 23.1% |
| 120-150k | 918 | 25.4% |
| 150k+ | 2,385 | 27.5% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |

What to check before buying a 2003 Hiace
On a 2003 Hiace, lighting & signalling is what the MOT record says goes wrong most — it appeared in 14.8% of tests. Check these areas before you commit.
- Lighting & signalling (14.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (14.1% 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.
- Body, structure & corrosion (8.0% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
