2021 KIA Niro 4 + EV Electric · RO71 YLL

The most recent DVSA MOT carried out on 4 October 2025 recorded a full pass with no recorded defects, following an identical clean result on the 18 October 2024 test. With two successive annual examinations showing no advisory or failure items, the maintenance trend can be regarded as stable and there is no evidence of emerging mechanical deterioration from the MOT perspective. At 64 259 miles the 2021 Kia Niro has accumulated roughly 12 850 miles per annum, a usage rate that exceeds the typical average for a five‑year‑old family hatchback. This level of mileage suggests that consumable wear items such as tyre tread, brake pads and discs, and suspension bushings will have experienced accelerated ageing compared with a lower‑mileage example. The plug‑in hybrid powertrain will also have logged a significant number of charge‑discharge cycles, which can influence the state‑of‑health of the high‑voltage battery, while the 12 V auxiliary battery may have been subjected to frequent start‑stop operations. Prospective buyers should give particular attention to the condition of the tyre sidewalls and tread depth, looking for cracking, dry rot or uneven wear that could indicate mis‑alignment or worn suspension components. A visual inspection of the front and rear suspension should verify the integrity of the coil springs, damper mounts and rubber bushings; any clunking or excessive play when the vehicle is pushed over bumps may point to deteriorated bushings or worn ball joints. The brake system warrants a thorough check of pad thickness and disc surface; surface rust is common on idle discs but deep scoring, glazing or pulsation under braking would suggest the need for resurfacing or replacement. Verify that the brake fluid has been changed within the last two years, as moisture absorption can reduce boiling point and affect pedal feel. Given the vehicle’s hybrid nature, the high‑voltage battery pack should be assessed for any warning lights on the instrument cluster and, if possible, a diagnostic read‑out of the state‑of‑health percentage. The 12 V lead‑acid battery, which powers the vehicle’s electronics, should be tested for cranking voltage and checked for signs of sulfation, especially if the car has spent long periods stationary. Inspect the coolant reservoir for correct level and colour, as the battery thermal management system relies on proper coolant circulation. Finally, confirm that the service book contains stamps for scheduled oil changes, filter replacements and any software updates recommended by Kia, as these are essential to maintain both the internal combustion engine and the electric drive components in optimal condition.
