2015 Isuzu D Max — MOT failures & pass rate
28,975 MOT tests on the 2015 Isuzu D Max are in this dataset, and 79.6% of them passed. Pick-up trucks of a similar age fail 19.3% of the time, so this is 1.1pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
Lighting & signalling dominates the failure mix at 11.8% of all tests — 3.5 points clear of suspension, so it is the first thing to check.
At component level the recurring items are position lamp, shock absorbers and rigid brake pipes — position lamp alone was recorded 1,449 times.
A 150k+ example is materially riskier than a 0-30k one: 26.6% versus 11.1%.
Advisories point at the next bill rather than this one: suspension was flagged on 28.8% of tests without failing them.
The trend is worsening — 18.0% of tests failed in 2021 against 23.5% in 2025, the usual pattern as a fleet ages.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.

| 6 | Other defects | 8.2% | 2,377 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |

What to check before buying a 2015 D Max
On a 2015 D Max, lighting & signalling is what the MOT record says goes wrong most — it appeared in 11.8% of tests. Check these areas before you commit.
- Lighting & signalling (11.8% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (8.3% 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 (7.9% 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.
