2014 Nissan NV400 2.3L Diesel · GN64 AAK

The Nissan NV400 presents a clean MOT history in its most recent test, with the May 2025 inspection at 243,889 miles showing no defects—an encouraging sign of current roadworthiness. However, the pattern of two consecutive failed tests on the same day in March 2023 (242,733 miles) and November 2021 (228,207 miles) raises questions about the vehicle’s handling between tests. Both failures occurred without recorded defects, which is unusual and suggests either administrative errors or a tester’s discretionary refusal, possibly due to minor but unresolved advisories not captured in the official record. The absence of any major faults in the passed tests indicates the vehicle met basic legal standards, but the repeated failures imply inconsistencies in maintenance or testing that warrant closer scrutiny before purchase. The NV400’s mileage of 243,889 over roughly 12 years—averaging around 20,324 miles annually—is high for its age, particularly given the long gaps between MOTs. The 15,682-mile jump between November 2021 and March 2023 suggests either intensive use or a period of neglect followed by rapid accumulation. More concerning is the 14-month gap between the November 2021 failures and the next test in March 2023, which exceeds the legal 12-month MOT interval. This irregularity could indicate the vehicle was driven without a valid certificate for nearly a year, a red flag for compliance and safety. The most recent MOT, just over a year ago, aligns with the legal schedule, but the lack of intermediate tests leaves critical wear patterns unrecorded. Given the sparse defect history, a buyer should prioritise a thorough inspection of high-wear components likely to degrade under heavy mileage. The suspension—including coil springs, anti-roll bars, and bushings—should be checked for fatigue, especially if the vehicle has been driven aggressively. Braking systems, including calipers, discs, and pads, demand particular attention, as binding or uneven wear could have been missed in tests without defects logged. Structural integrity is another concern; the NV400’s chassis and undercarriage should be examined for corrosion, particularly around wheel arches, exhaust mounts, and suspension points, given the high mileage and potential exposure to moisture. Finally, the drivetrain—transmission fluid levels, differential health, and exhaust emissions—should be verified, as these areas often show silent degradation in vehicles with inconsistent maintenance records.
