All Known Issues

Turbocharger Failure (2.5L)

SeriousEngine

The smaller of the two turbos on the 2.5L engine can suffer from bearing failure, often due to carbon-clogged oil feeds.

Est. Repair Cost: £800–£1,500
Warning Signs:

Whining/whistling noise, Blue smoke, Sudden loss of power

What to Inspect:
  • Evidence of 6,000-8,000 mile oil changes is better than the official long-life intervals
Verified by IsItAGoodCar Research Team

DPF Regeneration Issues

ModerateEngine

The DPF system on both the 2.5 and 1.9 can fail to clear during short journeys, leading to oil dilution.

Est. Repair Cost: £300–£1,500
Warning Signs:

DPF warning light, Rising oil level on the dipstick, Reduced fuel economy

What to Inspect:
  • Check the oil level; if it's significantly above the "full" mark, the oil is likely diluted with fuel

Chassis Surface Rust

MinorSuspension & Chassis

Factory undersealing was sparse. While not usually terminal on this generation yet, surface rust is very common.

Est. Repair Cost: £200–£600 (Cleaning & Sealing)
Warning Signs:

Visible orange oxidation on chassis rails and suspension components

What to Inspect:
  • Inspect the rear section of the chassis where mud accumulates

Buying Tips for 2017 Isuzu D-Max (Mk2)

  • Check the engine oil dipstick level; repeated aborted DPF regenerations can dilute engine oil with fuel
  • Confirm the engine pulls cleanly across the rev band; the 1.9 requires more revs than the older 2.5 unit
  • Inspect underbody protection plates and sill seams for off-road scraping, dents, or hidden mud traps
