2005 Mitsubishi Delica — MOT failures & pass rate
Across 1,140 MOT tests, the 2005 Mitsubishi Delica recorded a 68.8% pass rate. That is 3.7 percentage points worse than all cars of a similar age, which fail at 27.6%. Failures cluster in suspension, lighting & signalling and body, structure & corrosion.
What the MOT record shows
No single area dominates — suspension (18.3%) and lighting & signalling (16.4%) 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, rear fog lamp and integral vehicle structure condition — component mounting prescribed areas alone was recorded 231 times.
Condition tracks the odometer closely. Failures run at 24.0% in the 30-60k band and 34.2% in the 150k+ band, a 10.2-point spread.
Suspension is the most common advisory, noted on 35.4% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 32.2% in 2021 to 28.0% 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 |
|---|---|---|---|
| 1 | Suspension | 35.4% | 404 |
| 2 | Brakes | 32.4% | 369 |
| 3 | Emissions & environmental | 26.1% | 297 |

| 5 | Tyres | 15.3% | 174 |
| 6 | Lighting & signalling | 13.5% | 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 |
|---|---|---|
| 30-60k | 50 | 24.0% |
| 60-90k | 119 | 17.6% |
| 90-120k | 213 | 30.0% |
| 120-150k | 234 | 34.2% |
| 150k+ | 486 | 34.2% |
Failure rate by age
By fuel type
| Fuel | Tests | Fail rate |

What to check before buying a 2005 Delica
The failure pattern for this year is specific enough to inspect against: suspension accounted for 18.3% of tests. Start there.
- Suspension (18.3% 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.
- Lighting & signalling (16.4% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Body, structure & corrosion (12.7% 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.
