2014 Isuzu D-MAX 2.5L Diesel · SL14 ORW

Drivetrain component wear is the primary mechanical concern for this vehicle, specifically regarding the propulsion system's stability. While the 2014 Isuzu D-Max has maintained a consistent pass record, the most recent MOT on 16 October 2025 highlights emerging issues with the central prop shaft, noting both slight play in the bearing and a slightly deteriorated flexible coupling. This represents a shift from previous years where the focus was largely on minor suspension and visibility items, suggesting that the drivetrain is now entering a phase of wear that requires closer monitoring to prevent future failures. The vehicle has covered 134,385 miles over its twelve-year lifespan, averaging approximately 11,199 miles per year. This mileage accumulation is consistent with typical usage for a utility vehicle of this age and does not suggest periods of prolonged inactivity or excessive heavy-duty commercial use. Mechanically, this steady usage pattern implies that while the engine and gearbox have been subject to regular operating temperatures and load, the vehicle has not been subjected to the extreme wear associated with very high annual mileages, nor the potential degradation issues found in vehicles that sit idle for long periods. Prospective buyers should pay particular attention to the drivetrain during a test drive to address the advisories regarding the central prop shaft. Listen for any rhythmic vibrations, humming, or thumping noises emanating from the underside of the vehicle, particularly during acceleration or when cruising at motorway speeds. If the bearing or flexible coupling has significant play, you may also feel a shudder or oscillation through the floorpan or seat. It is essential to verify if these vibrations are constant or if they intensify with speed, as this will indicate the severity of the play in the prop shaft assembly. Furthermore, while the suspension issues noted in 2021 and 2022 regarding the upper arm ball joint dust covers and anti-roll bar bushes appear to have been addressed or have not recurred, the history of wear in these areas warrants a physical inspection. During the test drive, pay close attention to the steering response and listen for any clunking or knocking sounds when traversing uneven road surfaces or turning the steering wheel at low speeds. Any sudden pulling to one side or irregular steering feel could indicate that the previous suspension component wear has transitioned into a more significant mechanical fault.
