Isuzu D-Max Workman + MOT pass rate & common failures
Across 3 model years and 440 tests, the Isuzu D-Max Workman + passes its MOT 85.7% of the time. Against all cars of a similar age (10.0% fail rate), the D-Max Workman + comes out 4.4pp worse. Its most common failure areas are lighting & signalling, suspension and tyres.
What the MOT record shows
No single area dominates — lighting & signalling (6.6%) and suspension (5.5%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are shock absorbers, tread depth and wipers — shock absorbers alone was recorded 25 times.
Condition tracks the odometer closely. Failures run at 6.7% in the 0-30k band and 21.6% in the 60-90k band, a 14.9-point spread — more than double.
Advisories point at the next bill rather than this one: suspension was flagged on 19.6% of tests without failing them.
The trend is worsening — 15.3% of tests failed in 2022 against 20.8% in 2025, the usual pattern as a fleet ages.

| 0-30k | 135 | 6.7% |
| 30-60k | 176 | 14.8% |
| 60-90k | 88 | 21.6% |

What to check before buying a Isuzu D-Max Workman +
- Lighting & signalling (6.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (5.5% 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.
- Tyres (4.5% of tests): Usually a quick, known-cost fix, but check tread, age and uneven wear (which can hint at alignment or suspension issues). Typical repair: £50–£120 per tyre.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
