2021 KIA Niro 3 EV Electric · YS21 ABO

The most recent MOT on 8 June 2026 was passed, with three advisories concerning the rear tyres and two relating to child‑seat positioning that prevented a full adult‑belt inspection. The preceding year’s test (June 2025) recorded a clean pass and the 1 May 2024 test only flagged a minor cut on the near‑side rear tyre. Overall the maintenance trend appears stable in terms of mechanical integrity, but the recurrence of rear‑tyre advisories indicates a gradual progression of tyre perishing that should be addressed promptly. With a recorded 30 307 miles on a 2021 model, the vehicle averages just over 6 000 miles per annum, which is typical for a family‑size EV of this age. The mileage suggests the car has not been subjected to excessive high‑speed or heavy‑load duty, but the pattern of relatively low annual use also raises the possibility of periods of prolonged standing, which can accelerate tyre ageing and promote corrosion on suspension components if the car has been stored outdoors. Prospective buyers should give the rear tyres immediate attention. Inspect the sidewalls for any visible cracking, bulging, or dry‑rot, and measure tread depth across the width; a depth below 1.6 mm or uneven wear patterns would warrant replacement. During a test drive listen for any thudding or vibration that may indicate a developing separation of the tyre carcass, and feel for a loose sensation when applying torque to the steering wheel that could point to worn rear‑axle bushings. Because the advisories note “slightly damaged/cracking or perishing,” the tyres are likely approaching the end of their service life and should be replaced before the next MOT to avoid a failure. Beyond the tyres, the buyer should verify the health of the high‑voltage battery pack and the auxiliary 12 V battery, ideally by requesting a recent state‑of‑health report from a Kia service centre. Check that the coolant for the battery thermal‑management system has been changed according to the service schedule, and inspect the under‑body for any signs of corrosion on the chassis, brake lines, or mounting points, especially if the car has spent time idle. Examine the brake discs and pads for surface rust or glazing, remembering that regenerative braking reduces wear but does not eliminate the need for periodic inspection. Finally, confirm that the service book contains all scheduled software updates and that any outstanding recalls have been rectified, as these are critical for both safety and the longevity of an electric drivetrain.
