2014 Isuzu D-MAX 2.5L Diesel · MM14 XAW

The latest MOT test for the 2014 ISUZU D-MAX occurred on 2025-02-13, where it passed with several advisories, though no major failures were recorded. Comparing this to the previous MOTs, the trend shows a pattern of recurring minor issues rather than a clear deterioration or improvement. The vehicle’s history includes multiple advisories related to brake pipe corrosion, worn suspension bushes, and headlamp lens obstructions, alongside one major failure in 2019 concerning excessively worn shock absorber bushes and anti-roll bar components. While the 2025 test was clean of major defects, the persistence of corrosion and wear-related advisories suggests ongoing mechanical stress, particularly in the braking and suspension systems, which may indicate either neglect or high-stress usage over the years. The recorded mileage of 128,636 miles for a vehicle aged approximately 12 years represents a reasonable annual usage rate of around 10,720 miles, which is typical for a D-MAX of this age. However, the MOT history does not reveal any extreme mileage spikes that would suggest aggressive driving or rapid wear, but the consistent presence of advisories—particularly in the rear suspension and brake systems—could imply either prolonged standing without maintenance or gradual, cumulative wear from moderate use. The absence of significant gaps in the MOT schedule suggests the owner has prioritised testing, but the recurring defects warrant closer inspection of wear progression and potential underlying causes, such as poor lubrication or corrosion prevention. For a prospective buyer, the most critical areas to inspect are the rear suspension and braking systems, as the MOT history highlights persistent issues with corroded brake pipes and worn suspension bushes. On a test drive, listen for unusual clunking noises from the rear suspension, particularly when driving over bumps, as this may indicate further bush wear or suspension component failure. Check for uneven brake pedal travel or vibration, which could signal warped discs or binding calipers, and inspect the brake fluid level and condition for signs of contamination or degradation. The corroded brake pipes should be thoroughly examined for signs of rust propagation, which could lead to leaks or reduced braking efficiency if left unaddressed. Additionally, verify that the headlamps are functioning correctly and that no further obstructions are present, as the previous advisories suggest a history of lens contamination. Beyond the mechanical concerns, the vehicle’s age and mileage necessitate a thorough physical inspection of consumables and structural integrity. Given the recorded corrosion advisories, particularly on the underside and brake pipes, ensure the vehicle is parked on a dry, stable surface and inspect for signs of rust spreading to critical areas, such as the chassis or exhaust system. Check the tyre condition for sidewall cracking or perishing, which can occur even with low mileage due to age-related degradation, and verify the tread depth meets legal requirements. The 12V battery should be tested for charge retention and overall health, as standing vehicles can suffer from battery drain or corrosion in terminals. Lastly, consult the service records for the last fluid service, particularly the brake fluid, transmission fluid, and coolant, as these fluids degrade over time regardless of mileage, and their replacement is recommended every 2–3 years for optimal performance and safety.
