1996 Isuzu Trooper — MOT failures & pass rate
The 1996 Isuzu Trooper passed 72.5% of its 685 recorded MOT tests. That is 3.4 percentage points worse than large SUVs of a similar age, which fail at 24.1%. Failures cluster in body, structure & corrosion, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — body, structure & corrosion (14.4%) and lighting & signalling (12.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are chassis condition, component mounting prescribed areas and joints — chassis condition alone was recorded 66 times.
Mileage is the strongest signal on the record: 21.9% of 60-90k cars fail, rising to 29.1% once past 150k.
Suspension is the most common advisory, noted on 43.6% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 29.2% in 2021 to 26.1% 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 |
|---|---|---|---|
| 1 | Suspension | 43.6% | 299 |
| 2 | Brakes | 42.9% | 294 |
| 3 | Body, structure & corrosion | 39.0% | 267 |

| 5 | Other defects | 20.3% | 139 |
| 6 | Tyres | 14.6% | 100 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 60-90k | 41 | 21.9% |
| 90-120k | 104 | 27.9% |
| 120-150k | 176 | 25.6% |
| 150k+ | 350 | 29.1% |
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Diesel | 595 | 27.1% |
| Petrol | 90 | 30.0% |
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2021 | 195 | 29.2% |
| 2022 | 138 | 23.2% |
| 2023 | 130 | 25.4% |

What to check before buying a 1996 Trooper
The failure pattern for this year is specific enough to inspect against: body, structure & corrosion accounted for 14.4% of tests. Start there.
- Body, structure & corrosion (14.4% 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+.
- Lighting & signalling (12.7% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (12.7% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
