2023 KIA Niro 4 EV Electric · SM23 KMF

The 2023 Kia Niro 4 EV’s latest DVSA MOT test on 2026-06-04 resulted in a passing grade, though it included three advisories that warrant careful consideration. The absence of any failures or conditional defects in this test suggests that the vehicle has maintained a stable roadworthiness status over its short operational history, with no evidence of worsening mechanical issues. However, the presence of repeated advisories—specifically concerning the steering rack inner joint play, front tyre wear patterns, and rear brake disc condition—indicates that maintenance attention should be prioritised to mitigate potential long-term wear or safety risks. The fact that these advisories have not progressed to failures in this test alone does not absolve the buyer of due diligence, as such issues often escalate if left unaddressed, particularly in a vehicle with its current mileage and usage profile. The recorded mileage of 47,329 miles for a vehicle aged just three years represents a notably high annual usage rate of approximately 15,776 miles per annum, which is significantly above the average for its class and age. Such mileage accumulation typically accelerates wear on consumables like brake pads, suspension components, and tyres, as well as potential stress on drivetrain elements such as the steering system and drivetrain seals. The rapid mileage suggests either intensive use or a combination of frequent short trips and periods of prolonged standing, which can exacerbate issues like fluid degradation, corrosion from moisture ingress, and uneven tyre wear patterns. The front tyre advisories—particularly the edge wear—may indicate directional stability concerns or misalignment, which could be exacerbated by high mileage and aggressive driving styles. The rear brake disc pitting and scoring, while not severely weakened, should be monitored closely, as high-speed braking or heavy loads could accelerate further deterioration. For the prospective buyer, the most critical immediate actions should focus on the steering rack and tyre advisories. The play in the steering rack inner joint(s) is a common issue in electric vehicles, often linked to prolonged standing or exposure to moisture, which can lead to corrosion or joint degradation over time. On a test drive, listen for a noticeable stiffening or clunking sensation when turning, especially at low speeds, or feel excessive resistance when aligning the vehicle. The front tyres worn on the edges suggest either underinflation, misalignment, or directional instability, which can compromise handling and fuel efficiency. Inspect the tyres for uneven wear patterns, and ensure they are properly inflated to the manufacturer’s recommended pressure. If the wear is confirmed to be excessive, a wheel alignment and tyre rotation may be necessary to prevent further deterioration. In addition to the immediate advisories, a thorough pre-purchase inspection should include checks for tyre sidewall perishing or cracking, which can occur even at moderate mileage due to the vehicle’s age and the materials used in electric vehicles. Inspect the brake system for signs of corrosion on the discs or calipers, particularly if the vehicle has been stationary for extended periods, as standing fluid can cause rusting. Verify the condition of the 12V battery, as prolonged disuse or high mileage can impact its longevity, and consider testing its charge capacity if possible. Fluid servicing should be reviewed, with particular attention to the brake fluid, differential fluid, and coolant, as these fluids degrade over time regardless of mileage. Finally, check for any visible signs of exhaust emissions system corrosion or leaks, as electric vehicles may be more susceptible to moisture-related issues in the exhaust manifold or catalytic converter. If the vehicle has a service history, confirm that the manufacturer-recommended maintenance intervals—such as the first 10,000-mile service—have been adhered to, as this is critical for an EV’s electrical and mechanical components.
