2018 BMW I3 Electricity · SC18 FSN

The 2018 BMW i3 presents a stable and improving maintenance trend, culminating in a clean pass on 27 February 2026 at 37,326 miles with zero defects recorded. That same day also produced a failed test at 37,322 miles for a cut in the nearside rear tyre deep enough to expose the ply or cords, but the immediate retest passed, indicating the defect was rectified promptly. The overall trajectory is one of consistent compliance, with no recurring mechanical or structural failures across the recorded history. The mileage profile is notably low for an eight-year-old vehicle. Annual accumulation sits at roughly 4,666 miles, well below the UK average. Between the March 2025 test at 30,260 miles and the February 2026 test at 37,326 miles, the car covered approximately 7,066 miles in just under twelve months, which represents a modest uptick in usage compared to earlier years. Prior intervals were even quieter, with around 4,439 miles added between March 2024 and March 2025, and a similar figure between June 2023 and March 2024. The record is clean and consistent, with no gaps or anomalies suggesting long periods of inactivity or odometer irregularities. The only advisory-level defect in the entire history appeared in the June 2023 test at 20,051 miles, when the front brake disc was flagged as worn, pitted, or scored on the inner face but not seriously weakened. Given the low annual mileage, this is consistent with a vehicle that may spend extended periods stationary, allowing surface corrosion to form on brake discs between uses. A prospective buyer should inspect the current condition of all brake discs and pads, paying particular attention to uneven wear or lipping that could indicate the original disc was replaced or that calipers are dragging. The nearside rear tyre failure in February 2026 warrants a close visual inspection of all four tyres, including sidewalls and inner edges, to confirm no further damage or age-related cracking has developed since the replacement. Beyond the recorded defects, the i3's carbon fibre reinforced plastic body panels and aluminium chassis demand specific attention during any pre-purchase inspection. Examine the underbody and wheel arches for signs of corrosion on subframe mounting points or suspension components, as even low-mileage electric vehicles can suffer from environmental corrosion if stored in damp conditions. The suspension bushes, coil springs, and dampers should be checked for deterioration, and a test drive should confirm the regenerative braking system operates smoothly without judder or uneven deceleration.
