2021 KIA Niro 4 + EV Electric · LL71 AOG

The 2021 KIA NIRO 4+ EV’s latest MOT test on 2026-07-02 resulted in a clean pass, marking the vehicle’s fourth consecutive test without recorded defects or failures. This stability in MOT outcomes suggests a generally well-maintained drivetrain, emissions system, and structural integrity, though the prior failure in November 2024—particularly the dangerous near-side front tyre failure—indicates a critical oversight in tyre management. The advisory from that test, noting offside front tyre wear close to the legal limit, highlights a pattern of uneven tyre degradation, which could stem from misalignment, incorrect tyre pressure, or suspension issues. While the vehicle has since passed subsequent MOTs without tyre-related issues, the prior failure underscores the importance of addressing tyre wear progression promptly, as excessive edge wear can signal underlying alignment or load distribution problems that may worsen with continued use. The recorded mileage of 60,197 miles for a vehicle aged five years represents a relatively high annual mileage of approximately 12,039 miles per year, which is elevated for its class and age. Such usage typically accelerates wear on consumables like brake pads, suspension components, and internal engine seals, as well as on external parts such as tyres, exhaust components, and fuel system filters. The absence of significant mileage gaps suggests consistent, active use, which may have contributed to the observed tyre wear pattern. However, the high mileage also raises concerns about potential accelerated degradation of fluid-based systems, such as the brake fluid, coolant, and transmission fluid, which can degrade over time due to exposure to heat and repeated use. Additionally, the drivetrain and electrical systems, particularly in an electric vehicle, may experience wear from frequent charging cycles and thermal cycling, though the NIRO’s battery health would require independent inspection beyond the MOT. For a prospective buyer, the most urgent inspection should focus on the tyres, given the prior MOT failure and the advisory. Check the near-side front tyre for any signs of cracking, bulging, or further tread loss, as these can indicate underlying structural weakness or excessive heat exposure. On a test drive, listen for unusual tyre noise or vibrations, which may signal misalignment or uneven wear. The offside front tyre should also be examined closely, as edge wear can lead to hydroplaning risks and may require realignment or tyre replacement sooner than expected. Beyond tyres, verify the vehicle’s suspension for signs of excessive clunking or binding, which could correlate with worn suspension bushes, broken coil springs, or damaged control arms. Inspect the brake system for any signs of corrosion on discs or calipers, particularly on the near-side front, where standing corrosion is common. Additionally, check for any fluid leaks under the vehicle, as the high mileage may have accelerated degradation of the brake fluid, coolant, or transmission fluid, which should be replaced in line with manufacturer recommendations—typically every 2–3 years for brake fluid and 60,000–100,000 miles for coolant. Given the vehicle’s age and mileage, a thorough physical inspection should also include a check of the battery health, as electric vehicles are particularly susceptible to battery degradation from prolonged use and age. Look for signs of swelling, corrosion on the terminals, or reduced charge capacity, which could indicate a failing battery pack. Inspect the brake pads and discs for signs of excessive wear or corrosion, especially on the near-side front, where standing corrosion is more likely to cause binding calipers or reduced braking performance. Verify that all fluid reservoirs are full and that there are no visible cracks or leaks in the brake, coolant, or power steering reservoirs. Lastly, ensure that the service book is up to date, as the NIRO’s manufacturer may recommend specific time-based servicing intervals for the battery, electrical systems, and fluid replacements. If the vehicle has been in storage for extended periods, check for tyre sidewall perishing or cracks, as these can compromise structural integrity and safety.
