Isuzu D-Max Xtr + MOT pass rate & common failures
569 MOT tests on the Isuzu D-Max Xtr + (2019–2021) give it an 87.5% pass rate. All cars of a similar age fail 9.3% of the time, so this is 3.2pp worse than the group it competes with. Its most common failure areas are suspension, lighting & signalling and brakes.
What the MOT record shows
No single area dominates — suspension (6.3%) and lighting & signalling (5.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, leaf spring and wipers — headlamp aim alone was recorded 20 times.
Mileage is the strongest signal on the record: 6.9% of 0-30k cars fail, rising to 18.3% once past 60-90k — 2.6× the risk.
Suspension is the most common advisory, noted on 15.5% of tests — work that passed today but is likely due soon.
The trend is worsening — 12.0% of tests failed in 2023 against 14.3% in 2025, the usual pattern as a fleet ages.

What to check before buying a Isuzu D-Max Xtr +
- 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 (5.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (2.8% 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.
