2016 Isuzu D-MAX 2.5L Diesel · DL16 SCO

The 2016 Isuzu D-MAX presents a mixed maintenance picture, with a recent pass at 79,396 miles in June 2025 masking a pattern of recurring corrosion and suspension wear that has persisted for several years. The vehicle has not failed a test since June 2023, suggesting some remedial work was carried out, yet the same central brake pipe corrosion advisory has appeared in three consecutive annual tests from 2022 through 2025, indicating the underlying issue was managed rather than fully resolved. The most recent test also flagged a corroded towbar component and a nail in the nearside rear tyre, both minor but symptomatic of a vehicle that has received functional rather than thorough preventative care. The mileage progression is broadly consistent with light commercial or rural use, rising from 50,962 miles in June 2022 to 79,396 miles by June 2025, an average of roughly 9,500 miles per year over that three-year window. The 2023 failure and retest occurred within five days at the same recorded mileage of 59,791, confirming the faults were addressed promptly at that time. However, the gap between the 2023 and 2024 tests shows an accumulation of over 10,000 miles in twelve months, which is reasonable but does mean wear items such as brake components, tyres, and suspension bushes have been subjected to sustained use without a documented inspection in between. A buyer should focus their physical inspection on the brake pipe runs, particularly the central pipe and front-to-rear lines, which were flagged as excessively corroded in 2023 and have since reappeared with surface corrosion and grease contamination. The suspension also warrants close scrutiny. The 2023 failure identified a worn offside rear shock absorber bush, excessive play in the nearside track rod end, and a deteriorated upper suspension arm ball joint dust cover, all of which point to a vehicle that has been driven on uneven surfaces or used for towing without regular chassis checks. The offside rear seat belt was flagged as damaged in both 2022 and 2023, and while it was not mentioned in subsequent tests, the webbing should still be examined for fraying or slow retraction. Corrosion is the dominant theme across the record. Brake pipes, the towbar, and suspension mounting points have all attracted advisories, and the presence of grease on corroded pipework suggests cosmetic covering rather than proper replacement. The exhaust had a major leak in 2023, and although it passed in 2024 and 2025, the system should be checked for heat damage around the flanges and lambda sensor bungs. Tyre wear has been a recurring minor issue, with both rear tyres worn to the legal limit in 2023 and a puncture noted in 2025, suggesting the rear axle alignment and pressures have not been monitored consistently. Overall, this D-MAX appears mechanically serviceable but has a history of deferred corrosion management and suspension wear that a buyer should verify has been properly addressed before purchase.
