2020 Nissan Leaf Electric · DP70 LGV

The most recent MOT test on April 11, 2026, resulted in a failure—though no specific defects were recorded, this marks the first such outcome in over a year. The preceding tests in November 2024 and April 2025 had both passed without failings, suggesting a brief but notable decline in roadworthiness just before the latest test. The absence of advisories or defects in any of these records implies that, where tested, the vehicle met basic MOT standards, but the repeated failures without explanation raise questions about whether critical components were overlooked or if the test centre’s diagnostic focus was limited. The pattern is inconsistent rather than worsening or improving, as the failures cluster around the same mileage range (28,400–35,992 miles) without clear progression. The recorded mileage of 35,992 miles over six years equates to approximately 5,999 miles annually, which is unusually low for a vehicle of this age and type. The gaps between tests—particularly the 11-month span between the November 2024 failure and the April 2025 pass—suggest periods of inactivity, which could accelerate degradation of fluids, seals, and suspension components. The rapid mileage jump from 21,530 miles in November 2023 to 28,429 miles by November 2024 (6,900 miles in under a year) contrasts sharply with the slower accumulation thereafter, indicating either a change in usage or potential deferred maintenance during the higher-mileage phase. This irregular pattern warrants scrutiny of wear items like brake pads, tyres, and high-voltage battery health, as prolonged standing can lead to corrosion or degradation in critical systems. Given the lack of recorded defects, an in-person inspection should prioritise high-wear components that often fail without obvious MOT failings. The suspension—particularly coil springs, bushes, and dampers—should be checked for uneven wear or binding, as these are common in EVs where weight distribution affects handling. The brake system, including calipers, discs, and master cylinder, must be examined for uneven wear or fluid leaks, as binding brakes or corrosion could go unnoticed in a basic MOT. The high-voltage battery and its cooling system are critical; any swelling, leaks, or degraded cooling lines could pose serious safety risks, though these may not always trigger an MOT failure. Finally, the underbody should be inspected for corrosion, especially around wheel arches and subframes, as prolonged low mileage can mask rust progression until it compromises structural integrity.
