Where the Trooper fails its MOT
Where Isuzu Trooper cars that failed their 2025 MOT were marked down, as a share of all recorded failure items.
The specific items testers recorded most often were joints constant velocity boot split or insecure, no longer prevents the ingress of dirt (5.3%), position lamp not working (4.5%) and chassis condition or chassis has excessive corrosion, seriously affecting its strength within 30cm of a body mounting (3.8%). See every common Trooper MOT failure.
These are DVSA failure records across every Isuzu Trooper that failed, not a claim that every Trooper has these problems.
What should you check when buying a used Trooper?
The areas above, most common first, and what an MOT tester looks at in each.
1
Body, chassis, structure
Look underneath and along the sills for corrosion, and check for damaged or poorly repaired panels. 20.8% of Trooper failure items.
2
Brakes
Make sure the pedal feels firm, the car stops in a straight line, the handbrake holds on a slope and no brake warning light is showing. 20.6% of Trooper failure items.
3
Suspension
Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 18.6% of Trooper failure items.
4
Lamps, reflectors and electrical equipment
Walk round with every light on: headlights, brake lights, indicators, fog lights and the number plate lamp. Check no warning lights stay on after starting. 17.3% of Trooper failure items.
5
Visibility
Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 6% of Trooper failure items.

What the MOT record doesn't tell you
Knowing Isuzu Trooper failures cluster around body, chassis, structure and brakes tells you what to inspect. It tells you nothing about whether the car is safe to buy. An MOT does not show money still owed on the car, a write-off, a theft record or a clocked odometer.

Used Isuzu Trooper FAQs
Is the Isuzu Trooper reliable?
MOT data does not measure reliability. It records whether a car met the roadworthiness standard on the day of its test. What it does show is a 62.3% first-time pass rate for the Isuzu Trooper across 2,051 tests in 2025, below the 72.3% average for all cars.
What should I check before buying a used Isuzu Trooper?
On the car itself, start with the areas it most often fails on: body, chassis, structure, brakes and suspension. Then check the individual car's history: outstanding finance, insurance write-off records, stolen markers, mileage and previous keepers. None of these appear in the MOT record or on the V5C.
How do I check an Isuzu Trooper's history?
Enter the registration of the specific car. A Carpeep car history check reports outstanding finance, write-off category, stolen markers, mileage history, previous keepers, MOT and tax status, import and export markers and scrapped status in one £15 report.
MOT figures are aggregated from the DVSA MOT Anonymised data set for 2025 (class 4 initial tests, retests excluded), licensed under the Open Government Licence v3.0. MOT results describe roadworthiness at test, not mechanical reliability.
