2014 Nissan Leaf Electric · MM14 AEA

The most recent MOT tests on this 2014 Nissan Leaf reveal a concerning inconsistency rather than a clear trend. The vehicle passed on the 2026-03-24 test but failed immediately after on the same day—both at 68,985 miles—with no recorded defects. This duplication suggests either a technical error in the system or, more likely, a deliberate retest after an unrecorded minor issue. The preceding clean pass in March 2025 at 67,004 miles indicates no major failures over the past year, but the repeated retest at the latest interval raises questions about whether the vehicle was driven to the test station with a known issue. The lack of advisories or defects in the 2023 tests at around 64,900 miles further implies that, if maintenance was consistent, the vehicle has avoided serious wear. However, the double-test anomaly at the latest interval warrants scrutiny of whether the vehicle was pushed through a test without addressing a potential underlying fault. The mileage progression of approximately 5,700 miles per year is unusually low for a vehicle of this age, suggesting either minimal use or prolonged periods of inactivity. Between the 2023 and 2025 tests, the vehicle covered just 2,082 miles over 18 months, averaging around 116 miles per month. This stagnation could mean the vehicle was stored for extended periods, which may accelerate issues like battery degradation in an EV or suspension component drying out. The sudden jump to 1,981 miles between the 2025 and 2026 tests—nearly four times the previous annual average—could indicate recent increased usage, potentially stressing components like brakes or tyres. The absence of advisories in any test suggests no pre-existing warnings about wear, but the low mileage pattern implies the vehicle may not have undergone regular servicing, leaving some components unchecked. Given the lack of recorded defects but the anomaly at the latest test, a buyer should prioritise an inspection of the battery health and cooling system, as EVs are particularly sensitive to prolonged disuse. The suspension should be checked for worn bushes or coil springs, especially if the vehicle was stored for long periods, as rubber components can degrade even without mileage. Binding brakes or uneven wear on discs could explain the retest, so caliper function and rotor thickness should be verified. Additionally, the tyres—though not flagged in MOTs—should be examined for uneven wear or signs of neglect, as low mileage doesn’t always correlate with proper inflation or tread maintenance. The absence of corrosion advisories in recent tests is reassuring, but a thorough underbody check remains advisable, particularly around wheel arches and sills, given the vehicle’s age.
