2020 Isuzu D-Max Blade + — MOT failures & pass rate
The 2020 Isuzu D-Max Blade + passed 90.0% of its 301 recorded MOT tests. That is effectively the same as all cars of a similar age (9.3% fail rate), so the MOT record here is unremarkable in either direction. Failures cluster in suspension, lighting & signalling and tyres.
What the MOT record shows
No single area dominates — suspension (6.3%) and lighting & signalling (6.0%) 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 21 times.
A 60-90k example is materially riskier than a 0-30k one: 12.1% versus 2.6%.
Tyres is the most common advisory, noted on 18.3% of tests — work that passed today but is likely due soon.

| 6 | Emissions & environmental | 3.0% | 9 |
Failure rate by mileage
Higher-mileage cars tend to fail more — often the most useful guide to real condition.
| Mileage band | Tests | Fail rate |
|---|---|---|
| 0-30k | 78 | 2.6% |
| 30-60k | 140 | 12.9% |
| 60-90k | 58 | 12.1% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |
|---|---|---|
| 2023 | 91 | 9.9% |
| 2024 | 103 | 9.7% |
| 2025 | 100 | 11.0% |
What to check before buying a 2020 D-Max Blade +
The failure pattern for this year is specific enough to inspect against: suspension accounted for 6.3% of tests. Start there.
- Suspension (6.3% 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.
- Lighting & signalling (6.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Tyres (3.3% 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.
