Isuzu D-Max Blade + MOT pass rate & common failures
500 MOT tests on the Isuzu D-Max Blade + (2019–2020) give it an 89.2% pass rate. That is 1.1 percentage points worse than all cars of a similar age, which fail at 9.7%. Its most common failure areas are lighting & signalling, suspension and visibility.
What the MOT record shows
No single area dominates — lighting & signalling (6.0%) and suspension (5.6%) 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 30 times.
Mileage is the strongest signal on the record: 4.1% of 0-30k cars fail, rising to 17.1% once past 90-120k — 4.2× the risk.
Tyres is the most common advisory, noted on 18.0% of tests — work that passed today but is likely due soon.
The trend is worsening — 4.3% of tests failed in 2022 against 12.8% in 2025, the usual pattern as a fleet ages.

What to check before buying a Isuzu D-Max Blade +
- 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.
- Suspension (5.6% 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.
- Visibility (3.0% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
