Isuzu Trooper: MOT pass rate and reliability data

The Isuzu Trooper fails its first MOT more often than the average UK car, by 11.7 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 2,333 individual Isuzu Trooper tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 65% first-time pass rate means roughly 35 in every 100 Isuzu Troopers presented for MOT fail on the first attempt. That is worse than average, so budget for remedial work and treat a fresh 12-month MOT as a genuine selling point rather than a given. The average Isuzu Trooper tested had covered 139,706 miles and was built around 2000.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Isuzu Trooper sits 11.7 points below the national average, ranked 1,870 of 2,005 models. On one bought as repairable salvage, assume the mechanical side needs more than the visible accident damage, and pad your repair estimate accordingly.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Isuzu Trooper rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged Isuzu Troopers at UK salvage auction.

Most common MOT failures on a Isuzu Trooper

1. Body, cab or chassis excessively corroded at a mounting point, 7% of tests (30.65x the national rate for this defect)

3. Service brake efficiency below minimum requirement, 3.4% of tests (15.85x the national rate for this defect)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 4% of tests (9.63x the national rate for this defect)
5. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 6% of tests (6.39x the national rate for this defect)
6. Brake pipe damaged or excessively corroded, 6.5% of tests (6.05x the national rate for this defect)

From 2,336 DVSA-tracked Isuzu Trooper tests, 2024. DVSA testers marked 3.1% of these flagged Isuzu Trooper defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a Isuzu Trooper

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a Isuzu Trooper before it actually fails on it.

2. A wheel bearing with excessive play, 18.2% of tests (27.97x the national rate for this advisory)
3. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 17% of tests (13.69x the national rate for this advisory), also fails
4. A brake hose ferrule excessively corroded, 8.4% of tests (6.59x the national rate for this advisory)
5. Brake pipe damaged or excessively corroded, 37.6% of tests (6.07x the national rate for this advisory), also fails
6. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 27% of tests (4.85x the national rate for this advisory)
7. Exhaust system leaking or insecure, 9.9% of tests (3.47x the national rate for this advisory), also fails
8. Number plate inscription missing or illegible, 7.7% of tests (2.91x the national rate for this advisory)
9. A spring or spring component fractured or seriously weakened, 10.1% of tests (2.14x the national rate for this advisory)
10. A shock absorber damaged to the extent that it does not function or showing signs of severe leakage, 6.8% of tests (1.75x the national rate for this advisory)
