2012 Isuzu D-Max D/C Intercooler Td — MOT failures & pass rate
513 MOT tests on the 2012 Isuzu D-Max D/C Intercooler Td are in this dataset, and 72.5% of them passed. Against all cars of a similar age (21.6% fail rate), the 2012 D-Max D/C Intercooler Td comes out 5.9pp worse. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (16.8%) and suspension (14.0%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rigid brake pipes, position lamp and rear fog lamp — rigid brake pipes alone was recorded 45 times.
Mileage matters less than usual here: the 2012 D-Max D/C Intercooler Td fails 32.4% of the time in the 30-60k band and 28.9% at 150k+, a spread of only 3.4 points.
Advisories point at the next bill rather than this one: suspension was flagged on 34.1% of tests without failing them.
The trend is worsening — 24.3% of tests failed in 2021 against 30.7% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2012 D-Max D/C Intercooler Td
On a 2012 D-Max D/C Intercooler Td, lighting & signalling is what the MOT record says goes wrong most — it appeared in 16.8% of tests. Check these areas before you commit.
- Lighting & signalling (16.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (14.0% 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 (12.1% 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.
