2015 Isuzu D-MAX 2.5L Diesel · DS64 OBY

The 2015 Isuzu D-Max has passed its most recent MOT on 2025-10-10 at 46,303 miles, but the record reveals a concerning pattern of repeated, unresolved faults over multiple tests. The trend is clearly worsening, with brake pipe corrosion, suspension arm rust, and tyre degradation persisting across four consecutive MOTs. While no major failures have led to a fail result, the cumulative nature of these issues—particularly the widespread brake pipe contamination and structural corrosion—suggests neglect rather than routine maintenance. The presence of advisories on all four tyres in the last three tests indicates a failure to address even basic wear, which could pose a safety risk if left unchecked. The vehicle’s mileage progression shows unusually low annual usage, averaging just 4,209 miles over the past decade, which may explain the relatively low overall mileage at 46,303. However, the gaps between tests are irregular: the largest jump occurred between 2021 (30,923 miles) and 2022 (32,880 miles), a span of just 1,957 miles in a year, followed by a more typical 3,871 miles to the 2023 test. This inconsistency, combined with the persistence of faults, implies either infrequent driving or prolonged periods of inactivity, both of which accelerate corrosion and degradation. The absence of any major mechanical failures despite these conditions suggests the vehicle has been kept moving rather than properly serviced. A prospective buyer should prioritise an immediate inspection of the brake system, particularly the rear brake pipes and calipers, which have shown consistent contamination and corrosion across all recent tests. The front brake discs, flagged for wear and scoring in 2025, should be checked for uneven thickness or structural compromise. Suspension components, especially the front arms, exhibit rust but no immediate structural failure—though prolonged exposure to moisture or off-road use could accelerate weakening. Tyres, failing advisories in three consecutive tests, must be examined for residual tread depth and signs of internal damage, as perishing rubber poses a latent failure risk. Given the pattern, a full brake fluid flush, pipe replacement, and suspension bush inspection are advisable before committing to purchase.
