2013 Isuzu D-Max D/C Intercooler Td — MOT failures & pass rate
The 2013 Isuzu D-Max D/C Intercooler Td passed 74.8% of its 711 recorded MOT tests. That is 5.4 percentage points worse than all cars of a similar age, which fail at 19.8%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 17.0% of tests against 13.6% for the next-worst category.
At component level the recurring items are position lamp, shock absorbers and rear fog lamp — position lamp alone was recorded 63 times.
Mileage is the strongest signal on the record: 24.1% of 30-60k cars fail, rising to 31.2% once past 150k.
Suspension is the most common advisory, noted on 37.4% of tests — work that passed today but is likely due soon.
The trend is worsening — 23.2% of tests failed in 2021 against 26.6% in 2025, the usual pattern as a fleet ages.

What to check before buying a 2013 D-Max D/C Intercooler Td
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 17.0% of tests. Start there.
- Lighting & signalling (17.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (13.6% 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 (10.8% 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.
