2020 Isuzu D-Max Xtr + — MOT failures & pass rate
301 MOT tests on the 2020 Isuzu D-Max Xtr + are in this dataset, and 86.7% of them passed. All cars of a similar age fail 9.4% of the time, so this is 3.9pp worse than the group it competes with. Failures cluster in suspension, lighting & signalling and visibility.
What the MOT record shows
No single area dominates — suspension (7.3%) 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 leaf spring, headlamp and headlamp aim — leaf spring alone was recorded 14 times.
Mileage is the strongest signal on the record: 6.7% of 0-30k cars fail, rising to 22.0% once past 60-90k — 3.3× the risk.
Suspension is the most common advisory, noted on 16.6% of tests — work that passed today but is likely due soon.

What to check before buying a 2020 D-Max Xtr +
The failure pattern for this year is specific enough to inspect against: suspension accounted for 7.3% of tests. Start there.
- Suspension (7.3% 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.
- Visibility (2.7% 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.
