Isuzu D-Max D/C Intercooler Td MOT pass rate & common failures
Across 9 model years and 1,228 tests, the Isuzu D-Max D/C Intercooler Td passes its MOT 73.9% of the time. That is 5.6 percentage points worse than all cars of a similar age, which fail at 20.6%. Its most common failure areas are lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 16.9% of tests against 13.8% for the next-worst category.
At component level the recurring items are position lamp, shock absorbers and rigid brake pipes — position lamp alone was recorded 101 times.
Mileage matters less than usual here: the D-Max D/C Intercooler Td fails 28.7% of the time in the 30-60k band and 30.3% at 150k+, a spread of only 1.7 points.
Suspension is the most common advisory, noted on 36.2% of tests — work that passed today but is likely due soon.
The trend is worsening — 23.5% of tests failed in 2021 against 28.4% in 2025, the usual pattern as a fleet ages.

What to check before buying a Isuzu D-Max D/C Intercooler Td
- Lighting & signalling (16.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (13.8% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (11.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
