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. On a Isuzu Trooper bought as a 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 what damaged Isuzu Troopers actually sold for at UK salvage auction.

Most common MOT failures on a Isuzu Trooper

1. Body, cab or chassis excessively corroded at a mounting point, 6.2% of tests (30.79x the national rate for this defect)
2. Service brake efficiency below minimum requirement, 2.9% of tests (16.86x the national rate for this defect)
3. The strength or continuity of the load bearing structure within 30cm of any seat belt anchorage (a 'prescribed area') is significantly reduced or inadequately repaired, 3.7% of tests (16.13x the national rate for this defect)
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 3.4% of tests (9.49x 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, 4.9% of tests (5.88x the national rate for this defect)
6. Brake pipe damaged or excessively corroded, 4.8% of tests (5.77x the national rate for this defect)
7. A transmission shaft constant velocity joint boot missing or no longer prevents the ingress of dirt etc, 5.8% of tests (5.2x the national rate for this defect)
8. Exhaust system leaking or insecure, 3.9% of tests (5.12x the national rate for this defect)
9. Significant brake effort recorded with no brake applied indicating a binding brake, 3.2% of tests (4.19x the national rate for this defect)
10. Parking brake efficiency below minimum requirement, 2.7% of tests (2.72x the national rate for this defect)

From 4,551 DVSA-tracked Isuzu Trooper tests, 2024. DVSA testers marked 3.08% of these flagged Isuzu Trooper defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 4.97% nationally.
