2016 Isuzu D-MAX 2.5L Diesel · DN66 WDD

The most recent MOT inspection for this Isuzu D-Max passed on 19 November 2025, but the history reveals a concerning trend of deteriorating mechanical components and recurring structural issues. While the vehicle has successfully passed its last test, the recent failure in November 2025 for a nearside front wheel bearing with excessive play and a major suspension arm ball joint defect indicates that maintenance has been reactive rather than preventative. The progression from minor advisories regarding wheel bearings in 2024 to a significant failure in 2025 suggests that component wear is accelerating. Furthermore, the recurring issues with the exhaust system and the persistent corrosion advisories on the rear vehicle structure indicate that the vehicle is entering a phase where more substantial and costly repairs may be required to maintain legal roadworthiness. With 64,262 miles recorded over approximately ten years, the vehicle has averaged roughly 6,426 miles per year. This is relatively low mileage for a commercial utility vehicle of this age, suggesting it has likely been used for light duty or has spent significant periods stationary. While lower mileage generally implies less wear on the engine and drivetrain, it can be deceptive in a diesel pickup. Low annual usage often correlates with the corrosion issues noted in the MOT history, as vehicles that do not see regular, high-speed motorway use are more susceptible to moisture retention and salt buildup on the chassis and brake lines. The lack of heavy mileage does not negate the age-related degradation seen in the rubber components and the structural oxidation reported. A prospective buyer must pay close attention to the suspension and drivetrain during a test drive. The history of wheel bearing play and deteriorated ball joint dust covers means you should listen for any humming, grinding, or droning noises from the front end, especially at higher speeds, and check for any clunking sounds when turning the steering wheel or traversing uneven surfaces. The advisory regarding the exhaust gas leak from the front pipe flexi should be monitored; you may notice increased engine noise, a slight smell of fumes in the cabin, or a change in exhaust note. Given the history of excessive brake pipe corrosion, it is vital to inspect the underside of the vehicle for any signs of weeping fluid or further degradation of the hydraulic lines, as this has been a recurring failure point for this specific vehicle. Finally, the advisories regarding corrosion on the nearside and offside rear vehicle structure are significant. While the tester noted that structural rigidity is not currently reduced, corrosion is a progressive condition. You should inspect the chassis rails and rear mounting points for heavy scaling or perforation. Because the vehicle has low annual mileage, also check the tyres for sidewall cracking or perishing, which can occur from age even if the tread depth remains high. Ensure the service history confirms that fluids, such as brake fluid and coolant, have been changed based on time intervals rather than just mileage, as the low usage profile can lead to moisture contamination in the braking system and chemical degradation of engine oils.
