2020 Nissan Leaf Electric · LS20 OAV

The most recent DVSA MOT test on 2026-05-06 resulted in a failure, with the vehicle displaying multiple critical defects alongside persistent advisories that had previously passed. While the prior MOT on 2025-05-08 was clean, the pattern of recurring issues—particularly the rear brake pad wear advisory and supplementary restraint system fault—suggests a maintenance trend that has not stabilised. The front windscreen wiper failures, which failed two consecutive tests, indicate a potential mechanical or electrical issue with the wiper motors or linkages, warranting immediate attention to prevent further windscreen damage or driver distraction. The advisory on the front brake disc pitting from the 2024 test also remains unresolved, hinting at ongoing wear that could compromise braking performance if not addressed. The vehicle’s recorded mileage of 58,638 miles at the time of this assessment represents a moderate annual usage rate of approximately 9,773 miles per year, which is within the typical range for a six-year-old Nissan Leaf under UK conditions. This usage level suggests a balance between active use and periods of inactivity, which can lead to specific wear patterns. Lower mileage could imply prolonged stationary periods, potentially causing issues such as battery degradation from residual charge cycling, corrosion in the battery terminals or electrical connections, or standing corrosion on the chassis or exhaust system. Conversely, higher mileage accumulation over shorter periods might accelerate wear on consumables like brake pads, tyres, and suspension components, though the Leaf’s electric powertrain mitigates some of these concerns compared to internal combustion engines. Given the recurring MOT advisories and failures, the prospective buyer should conduct a thorough mechanical inspection before purchase. Focus on the rear brake system, as the thin pad condition is a critical warning sign; listen for uneven brake pedal travel or a spongy feel, and visually inspect the rear brake discs for scoring or warping. The supplementary restraint system fault may stem from a faulty airbag sensor or wiring, so check for any unusual dashboard warning lights or a lack of response when the seatbelt is engaged. Test drive the vehicle to assess the wiper functionality—ensure both motors operate smoothly and clear the windscreen evenly without excessive noise or vibration, as a binding linkage or motor failure could lead to windscreen damage. Additionally, verify the front brake discs for binding or excessive heat discolouration, which could indicate overheating or hydraulic issues. For the Nissan Leaf’s age and mileage, the buyer should also examine the battery health, as prolonged inactivity can degrade the lithium-ion cells, leading to reduced range or failure. Check the battery terminals for corrosion or loose connections, and assess the overall condition of the battery housing for signs of swelling or physical damage. Inspect the tyres for sidewall cracking or perishing, which can occur even at moderate mileage due to the Leaf’s age, particularly if stored in a warm environment. Fluid servicing should be timed based on calendar intervals rather than mileage, with the brake fluid, coolant, and transmission fluid checked for degradation, as electric vehicles are susceptible to fluid breakdown over time. Finally, verify the structural integrity of the vehicle, paying close attention to the chassis for any signs of rust, particularly around the wheel arches and underbody, where moisture can accumulate. If the vehicle has been stored for extended periods, consider a professional inspection to address potential electrical or battery-related issues before purchase.
