1994 Isuzu Trooper — MOT failures & pass rate
Across 408 MOT tests, the 1994 Isuzu Trooper recorded a 72.5% pass rate. That is 3.8 percentage points worse than large SUVs of a similar age, which fail at 23.7%. Failures cluster in body, structure & corrosion, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — body, structure & corrosion (14.9%) and brakes (14.2%) 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 service brake performance — chassis condition alone was recorded 50 times.
A 150k+ example is materially riskier than a 60-90k one: 30.4% versus 20.0%.
Suspension is the most common advisory, noted on 33.3% of tests — work that passed today but is likely due soon.

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 | 33.3% | 136 |
| 2 | Brakes | 32.8% | 134 |
| 3 | Body, structure & corrosion | 31.1% | 127 |

| 5 | Tyres | 15.2% | 62 |
| 6 | Other defects | 10.3% | 42 |
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 | 35 | 20.0% |
| 90-120k | 58 | 25.9% |
| 120-150k | 85 | 27.1% |
| 150k+ | 217 | 30.4% |
By fuel type
| Fuel | Tests | Fail rate |
|---|---|---|
| Diesel | 363 | 29.2% |
| Petrol | 45 | 13.3% |
Trend over time

What to check before buying a 1994 Trooper
The failure pattern for this year is specific enough to inspect against: body, structure & corrosion accounted for 14.9% of tests. Start there.
- Body, structure & corrosion (14.9% 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+.
- Brakes (14.2% 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.
- 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
