2021 KIA Niro 4 + EV Electricity · PX71 UEO

The vehicle remains roadworthy, but the maintenance trend shows the onset of wear on the rear suspension components. While the car passed its latest test in December 2025 at 85,943 miles, the introduction of specific advisories indicates a shift from the previous record. The tester flagged both the nearside and offside rear trailing arm mounting bushes as split, suggesting that the rubber components are reaching the end of their functional life due to the high-use nature. The mileage profile is significant for a five-year-old vehicle, averaging approximately 17,200 miles per year. Between the November 2024 test at 69,069 miles and the December 2025 test at 85,943 miles, the car covered 16,874 miles in just thirteen months. This rapid accumulation suggests consistent long-distance motorway use, which typically accelerates the degradation of suspension bushings and drivetrain components compared to average private ownership patterns. A buyer should prioritize a physical inspection of the rear suspension geometry to assess the extent of the split trailing arm bushes. Since both sides were flagged simultaneously, the wear is likely uniform and will require replacement to prevent unpredictable handling or uneven tyre wear. The buyer should also verify the condition of the control arm pins and ball joints, as the high annual mileage places substantial stress on these mechanical pivot points.
