2015 Vauxhall Insignia 2.0L Diesel · LP64 NWZ

The Vauxhall Insignia’s most recent MOT history reveals a concerning pattern of repeated failures despite no recorded defects on either test date. The vehicle failed twice in January 2026 at nearly identical mileages (72,449 and 72,451), a stark anomaly given the clean passes in January 2025 and January 2024. This suggests the tester identified a non-obvious fault—likely related to emissions, suspension binding, or structural corrosion—though the absence of defect notes means the issue wasn’t categorised under standard MOT failure criteria. Buyers should treat this as a red flag for either a poorly documented fault or a vehicle that has slipped through MOT loopholes, potentially masking underlying wear. The mileage progression of 6,586 miles annually over 11 years is typical for its class, but the abrupt failure in January 2026—just two days after passing—implies either a sudden component failure or a tester’s heightened scrutiny. There are no gaps in testing beyond the standard 12-month intervals, and no evidence of excessive standing periods. However, the lack of defects on prior passes contrasts sharply with the 2026 failures, warranting closer inspection of components that might degrade incrementally, such as suspension bushes or coil springs, which could develop binding or excessive play over time. Given the repeated failures without explicit defect notes, a buyer should prioritise an independent inspection of the suspension system, particularly the rear axle and bushings, which are common failure points in this model. The binding brakes or uneven tyre wear that often accompany suspension issues should also be checked, as should the exhaust system for leaks or corrosion that might trigger emissions failures. Structural integrity—especially around the wheel arches and sills—must be scrutinised for hidden rust, as this is frequently the cause of "no-defect" MOT failures. The engine bay should be examined for fluid leaks or degraded hoses, which could indicate long-term neglect despite the clean MOT history.
