2021 Renault ZOE Electric · ML70 KNY

The Renault Zoe in question has maintained a stable roadworthiness record over the past three annual MOT tests, with only a single minor advisory noted in the most recent February 2026 inspection at 42,005 miles. The tester flagged the offside rear brake disc as worn, pitted, or scored but confirmed it was not seriously weakened—a clear indication of controlled wear rather than neglect. Prior tests in February 2025 and 2024, at 30,740 and 26,609 miles respectively, showed no defects at all, suggesting the vehicle has been well-maintained in terms of core mechanical and safety systems. The absence of any major failures or recurring defects implies that routine servicing has been adhered to, though the single advisory on the rear brake disc now requires attention to prevent potential binding or uneven braking performance. The mileage progression—averaging roughly 8,400 miles per year over five years—aligns closely with typical usage for a vehicle of this age, neither excessively low nor alarmingly high. The recorded figures show steady accumulation without sudden spikes or prolonged inactivity, which would otherwise raise concerns about suspension wear, battery health (critical for EVs), or corrosion from prolonged exposure. The most recent MOT at 42,005 miles was completed just five months ago, meaning the vehicle has not been driven significantly since then. While this could indicate recent purchase or storage, it also means the brake disc advisory remains unresolved, and no further wear data is available to assess whether the condition has stabilised or deteriorated. For a prospective buyer, the primary focus should be verifying the condition of the rear brake system, particularly the offside disc and corresponding caliper. Given the advisory was noted in February 2026, the disc may now require replacement if pitting has worsened, especially if the vehicle has been stationary. The absence of other defects in recent tests reduces immediate concerns about structural integrity, suspension components, or exhaust emissions, but a thorough inspection of the remaining brake discs, pads, and hydraulic lines is advisable. Additionally, checking for any signs of corrosion on the underbody or wheel arches—common in electric vehicles due to high-voltage components—would provide further reassurance on long-term reliability. The battery cooling system and high-voltage cables should also be visually inspected, as these are critical but often overlooked in used EVs.
