2004 Isuzu Rodeo — MOT failures & pass rate
Across 2,872 MOT tests, the 2004 Isuzu Rodeo recorded a 72.7% pass rate. Pick-up trucks of a similar age fail 29.0% of the time, so this is 1.8pp 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 (16.5%) and suspension (14.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are chassis condition, rear fog lamp and ball joint — chassis condition alone was recorded 258 times.
Condition tracks the odometer closely. Failures run at 20.2% in the 30-60k band and 29.6% in the 150k+ band, a 9.5-point spread.
Advisories point at the next bill rather than this one: suspension was flagged on 42.6% 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 | 42.6% | 1,224 |
| 2 | Brakes | 30.6% | 879 |
| 3 | Body, structure & corrosion | 24.2% | 696 |
| 4 | Tyres | 18.5% | 531 |
| 5 | Emissions & environmental | 18.4% | 530 |
| 6 | Lighting & signalling | 13.5% | 388 |
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 | 134 | 20.2% |
| 60-90k | 377 | 24.1% |
| 90-120k | 538 | 25.3% |
| 120-150k | 816 | 28.7% |
| 150k+ | 993 | 29.6% |
Failure rate by age

What to check before buying a 2004 Rodeo
On a 2004 Rodeo, lighting & signalling is what the MOT record says goes wrong most — it appeared in 16.5% of tests. Check these areas before you commit.
- Lighting & signalling (16.5% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (14.7% 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 (11.1% 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.
