What should you check when buying a used D-MAX?

The areas above, most common first, and what an MOT tester looks at in each.

1

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. 25.9% of D-MAX failure items.

2

Suspension

Listen for knocks over bumps, check the car sits level, and look for leaking shock absorbers and split rubber gaiters. 22.7% of D-MAX failure items.

3

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. 20.3% of D-MAX failure items.

4

Visibility

Check the windscreen for chips or cracks in the driver's view, and that the wipers and washers clear it properly. 7.7% of D-MAX failure items.

5

Body, chassis, structure

Look underneath and along the sills for corrosion, and check for damaged or poorly repaired panels. 7.2% of D-MAX failure items.

None of this replaces the car's own record. Run a free MOT history check on the registration to see every test, advisory and recorded mileage for that car.

What the MOT record doesn't tell you

Knowing Isuzu D-MAX failures cluster around lamps, reflectors and electrical equipment and suspension 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 D-MAX FAQs

Is the Isuzu D-MAX 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 70.9% first-time pass rate for the Isuzu D-MAX across 37,259 tests in 2025, below the 72.3% average for all cars.

Do older Isuzu D-MAX cars fail their MOT more often?

Isuzu D-MAX cars aged 3 to 5 years passed 79.3% of MOT tests in 2025; for examples aged 11 years and over that fell to 60.9%. On an older example, the car's own MOT history tells you more than the model average.

What should I check before buying a used Isuzu D-MAX?

On the car itself, start with the areas it most often fails on: lamps, reflectors and electrical equipment, suspension and brakes. 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 D-MAX'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.
