2012 Isuzu TF 2.5L Diesel · ML61 WBT

The vehicle shows a recent improvement in roadworthiness following a significant period of mechanical decline. While the March 2026 test at 129,242 miles resulted in a clean pass with no defects, the preceding December 2025 failure was extensive and indicated a serious lapse in maintenance. That failure included critical issues such as a near-total loss of parking brake efficiency, an ABS fault, and a nearside front wheel bearing with excessive play likely to lead to imminent failure. The transition from a heavy failure in late 2025 to a clean pass in early 2026 suggests that the major mechanical faults identified were addressed, but the history shows a pattern of reactive rather than preventative care. The mileage accumulation is consistent with a vehicle of this age, averaging approximately 9,200 miles per year. The records show steady usage, moving from 81,902 miles in February 2020 to 129,242 miles in March 2026. There are no significant gaps in the testing timeline, which provides a reliable longitudinal view of the vehicle's condition. However, the density of failures between 2021 and 2025 suggests that as the vehicle aged, the frequency of component wear increased, particularly regarding the drivetrain and braking systems. A prospective buyer should focus heavily on the drivetrain and suspension components. The record shows recurring issues with the prop shaft and centre bearings, with a failure in December 2025 specifically flagging an excessively worn centre bearing. The history of wheel bearing play and steering linkage issues, such as the ball joint play noted in October 2022, suggests the front-end assembly has undergone significant stress. Furthermore, the repeated mentions of corroded brake pipes and the inability of testers to inspect the underside due to stone guards in 2021 indicate that structural corrosion may be present and hidden. Braking system reliability is another area requiring close physical inspection. The parking brake has been a persistent issue, with efficiency problems noted in December 2024 and a severe failure in December 2025. Although the March 2026 pass suggests the cables and efficiency are now within limits, the history of insecure cables and stiff operation warrants a thorough check of the rear mechanism. Checking the condition of the shock absorber bushes and the integrity of the leaf spring saddles is also advised, as these components have appeared in several previous failure reports.
