2014 Isuzu D Max — MOT failures & pass rate
The 2014 Isuzu D Max passed 77.8% of its 25,231 recorded MOT tests. Pick-up trucks of a similar age fail 21.1% 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
One area stands out: lighting & signalling, recorded in 13.2% of tests against 9.9% for the next-worst category.
At component level the recurring items are shock absorbers, rear fog lamp and rigid brake pipes — shock absorbers alone was recorded 1,629 times.
Condition tracks the odometer closely. Failures run at 11.3% in the 0-30k band and 27.7% in the 150k+ band, a 16.4-point spread — more than double.
Suspension is the most common advisory, noted on 31.8% of tests — work that passed today but is likely due soon.
The trend is worsening — 19.9% of tests failed in 2021 against 24.3% in 2025, the usual pattern as a fleet ages.

| 5 | Lighting & signalling | 10.0% | 2,530 |
| 6 | Other defects | 9.4% | 2,363 |
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 2014 D Max
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 13.2% of tests. Start there.
- Lighting & signalling (13.2% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (9.9% 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 (8.9% 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.
