2009 Nissan Interstar 2.5L Diesel · LG59 OGW

The 2009 Nissin Interstar presents a mixed roadworthiness picture marked by a persistent pattern of suspension system degradation that has progressed from minor play to a failed test, alongside recurrent tyre wear and emerging drivetrain concerns. The most recent MOT on 2026-06-15 returned a pass despite accumulating new minor issues, with the nearside front drive shaft constant velocity boot classifying as a severe deterioration while noting underlying subframe corrosion. Earlier in 2023, the vehicle failed its test on 2023-10-25 due to excessive wear on the offside front upper suspension arm ball joint and accompanying tyre wear that approached legal limits, a problem that reappeared as a recurring advisory at the subsequent 2023-10-30 test along with front upper and lower suspension arm ball joint play. This escalating failure mode suggests the original suspension arm bushings have suffered progressive fatigue rather than being replaced early enough, and the 2026-06-15 result indicates the drive shaft assembly now requires immediate attention before further damage occurs. At 124,552 miles on a seventeen-year-old vehicle, the annualisation of approximately 7,300 miles places the car within expected usage parameters for its age, though the gap between the last two MOTs—spanning nearly sixteen months from late 2023 to mid-2026—is notably longer than the intervening tests. While the 2024-11-11 and 2025-01-20 period (implied by the absence of records) would typically indicate continued gradual wear, the extended interval since the last failure means no intermediate assessment exists for the current condition. The lack of a MOT between October 2023 and June 2026 creates uncertainty about how the previously identified suspension arm play and tyre wear have evolved, particularly whether additional wear has accumulated on the remaining suspension components during the interim. Given the consistent nature of the tyre scrubbing reported in 2022 and again in 2023, the front tyres appear to be experiencing accelerated wear patterns that may affect handling and braking performance if left unchecked. The primary mechanical concerns demand focused attention during a test drive. The nearside front drive shaft constant velocity boot deterioration reported in June 2026 should be inspected for signs of complete separation or internal lubricant depletion, which could lead to increased vibration and potential drive shaft failure under load. The persistently worn front tyres, documented as approaching legal limits and exhibiting edge wear across multiple assessments, require verification of tread depth and lateral grip during cornering and braking maneuvers, as compromised tyres can mask underlying suspension deficiencies. Additionally, the earlier failure involving the offside front upper suspension arm ball joint excessively worn necessitates checking the associated suspension arm for play when rotating the wheel by hand, listening for knocking noises over bumps, and confirming proper rebound during compression and extension cycles. If the drive shaft boot shows visible cracks or hardening beneath the rubber, replacement is strongly advised before proceeding with further driving, as continued deterioration could compromise power transmission and increase the risk of costly repair.
