2018 Isuzu D-MAX 1.9L Diesel · SL68 VCY

A pattern of front suspension wear and brake line corrosion dominates the recorded MOT history of this 2018 Isuzu D-Max, with the 2025 test cycle exposing the most serious mechanical concerns to date. On 13 October 2025 the vehicle failed outright, driven by a nearside front lower suspension ball joint recorded as excessively worn, a category A Major defect, alongside a nearside front wiper failing to clear the windscreen effectively and an offside front wiper blade noted as defective. Just two days later, on 15 October 2025, the vehicle returned and passed, although an advisory was issued for a damaged front bumper taped into position. The 2024 cycle followed a near-identical structure: a fail on 10 October 2024, caused by front brake pads worn below the 1.5 mm Dangerous threshold, followed by a pass on 11 October 2024 with advisories for slight corrosion on all four brake pipes and worn front anti-roll bar D bushes. The 2023 test passed with the same D-bush advisory, and the 2022 test was entirely clean. The overall trajectory therefore shows a stable record through the first three years of testing followed by a marked deterioration in 2024 and 2025, with the suspension ball joint failure on the nearside front being the most pressing structural concern. At 48,844 miles over approximately eight years, the D-Max is accumulating roughly 6,100 miles per year, which sits squarely within typical usage parameters for a working pickup of this age. There are no significant gaps between test dates, and the mileage progression between annual tests is consistent, indicating the vehicle has remained in regular service rather than being laid up for extended periods. Annual mileages in the 6,000 to 7,000 mile bracket mean the mechanical components flagged in the record have accumulated wear gradually rather than under heavy commercial use, which tends to extend the life of suspension joints and brake components but does not eliminate them. The relatively modest annual mileage does, however, mean that the components now showing wear have likely been exposed to several years of underbody corrosion cycles, which aligns with the brake pipe advisories observed in both 2024 test attempts. Prospective buyers should treat the front suspension as the primary area of mechanical scrutiny. The 2025 Major defect on the nearside front lower ball joint and the advisory for slight play in the offside front ball joint indicate progressive wear in the front suspension geometry that warrants a physical inspection on a ramp or over a pit. On a test drive, listen for clonking or knocking noises from the front end over speed humps, uneven surfaces, and during full-lock low-speed manoeuvres, as these are characteristic symptoms of worn ball joints. Pay particular attention to steering precision: any vagueness, knocking through the steering wheel, or uneven tyre wear across the front axle could point to the same components. The front anti-roll bar D bushes, flagged as worn in both 2023 and 2024, contribute to body roll and cornering stability; if they have deteriorated further since the last test, the vehicle may exhibit increased roll during lane changes and clunks over rough tarmac. The braking system requires equally close attention given the 2024 Dangerous failure for pads below 1.5 mm. While replacement pads would have been fitted to secure the pass, the brake pipe corrosion advisories recorded on all four corners suggest the underbody braking hardware has been exposed to moisture and road salt. On inspection, examine the brake pipes along their full length for blistering, flaking, or pitting corrosion, particularly at unions and mounting clips, as the 2024 advisories noted only slight corrosion at that point and progression over another year is plausible. During a road test, check for a soft or spongy brake pedal, any pulling to one side under braking, or grinding noises, all of which could indicate uneven pad wear, a binding caliper, or compromised pipework. Finally, the taped front bumper should be inspected for underlying structural damage to the bumper reinforcement, as tape is not a durable fix and may mask impact damage that could affect panel alignment or sensor mounting if any are fitted.
