2016 Nissan Leaf Electricity · AF66 WNA

The most recent DVSA examination on 26 March 2026 returned a PASS with no defects recorded, which is a positive immediate indicator. However, evaluating the broader trend reveals a pattern of escalating rear brake concerns culminating in a Dangerous failure on 25 March 2026. On that occasion, the rear inner brake pads were recorded at less than 1.5 mm, the parking brake efficiency fell below 50 percent of the required value, the offside rear service brake was binding, and the rear brake discs were noted as worn, pitted, and scored. The 2025 test also flagged offside rear brake disc wear, fluctuating offside rear brake performance, and a defective rear wiper blade, while a 2024 failure identified an excessively worn offside front suspension arm ball joint. The cumulative picture suggests the vehicle has been attended to for the immediate dangerous items but retains underlying wear in the rear braking system and front suspension that warrants close scrutiny before purchase, particularly given that the latest pass was achieved only one day after the dangerous failure was recorded. The recorded mileage of 56,791 miles across approximately ten years equates to a low annual average of around 5,679 miles, which is notably below typical usage for a vehicle of this age. The MOT record shows a gap between September 2021 and March 2022, and broadly consistent annual tests thereafter with no dramatic mileage surges visible from the recorded odometer readings. Low annual mileage in a battery electric vehicle such as the Nissan Leaf can be mechanically beneficial for high-wear items like brake pads and discs due to greater reliance on regenerative braking, but it also raises the likelihood of standing-related deterioration. Prolonged periods of inactivity can lead to brake disc corrosion and binding calipers, deteriorated coolant and brake fluid from calendar ageing rather than mileage accumulation, and crucially for an EV, potential degradation of the 12V auxiliary battery and the high-voltage traction battery if the vehicle has been left at high or low states of charge for extended periods. A prospective buyer should treat the recent rear brake history as the primary inspection priority. The dangerous pad wear and binding caliper noted in March 2026 should be verified as fully rectified, with invoices or receipts for the replacement of rear pads, caliper refurbishment, and any disc machining or replacement. On a test drive, listen for any rear brake squeal, grinding, or dragging sensation, and verify that the parking brake holds the vehicle firmly on an incline without excessive lever travel or warning indicators. Inspect the rear discs visually for lipping, scoring, or blueing from heat, and check that the caliper pistons retract cleanly. Given the offside front suspension arm ball joint replacement in 2024, conduct a thorough examination of the front suspension for any clunks over speed humps or uneven road surfaces, uneven tyre wear indicating camber or tracking issues, and perished or split suspension bushes, which are common on a ten year old vehicle regardless of mileage. Beyond the recorded defects, age-related items demand specific attention. Tyres may exhibit sidewall perishing or cracking from age even if the tread depth remains adequate, so inspect the sidewalls carefully and check the manufacturing date stamps. Verify the condition of the 12V auxiliary battery, as failed auxiliary batteries are a common cause of non-start and warning light issues in the Leaf, and confirm the health and state of charge of the traction battery through a dealer-level diagnostic if possible, as degradation is the single most important factor in used Leaf valuation. Examine the underside and wheel arch liners for corrosion, particularly around suspension mounting points and the rear subframe, and inspect the charging port and cables for wear or damage. Finally, confirm that brake fluid and coolant have been replaced within manufacturer service intervals irrespective of mileage, as both degrade chemically over time and their condition is not visible from the MOT record alone.
