2021 KIA Niro 2 Phev S-A 1.6L Hybrid electric (clean) · CF70 AFZ

Tyre integrity dominates the mechanical profile of this 2021 Kia Niro PHEV. The most recent test on 01 June 2026 was a fail driven by an inoperative rear registration plate lamp, with an advisory recorded for an offside rear tyre worn close to the legal limit and on its edge; a pass was issued the same day once the lamp defect was rectified. Earlier, on 19 May 2025, the vehicle failed on dangerous and major tyre defects, with ply or cords exposed on both edges and a cut deep enough to reach the cords across the tread or inner edge. A November 2024 test had flagged both front tyres as slightly damaged with cracking or perishing. The pattern across five years of testing is clear: while the chassis, braking, and suspension systems have not attracted any advisories, the tyres have been a persistent and recurring source of failure, with a dangerous defect recorded within the last eighteen months. Any prospective buyer should treat the tyres as an immediate rectification cost rather than a deferred maintenance item. The recorded mileage of 85,954 against an approximate five-year age equates to around 17,191 miles per year, which is notably high for a plug-in hybrid of this vintage. PHEV powertrains tend to be used for shorter urban commutes to maximise electric-only running, so annual figures in this region suggest this Niro has been subjected to substantially more long-distance or high-mileage use than its segment typically sees. The testing cadence has been consistent and frequent, with multiple passes recorded across 2024 and 2025 and no extended off-road gaps. From a mechanical standpoint, this accumulation rate accelerates wear on friction materials, suspension bushes, and drivetrain components, and the tyre wear pattern observed is consistent with a vehicle that has been covering significant distance rather than sitting idle. On a physical inspection, particular attention should be paid to the tyres as a set. Check the tread depth across the full width of all four tyres, paying close attention to the inner and outer edges, as the 2025 dangerous failure specifically cited both edges and the 2026 advisory noted edge wear on the offside rear. Uneven shoulder wear can indicate suspension misalignment, worn bushes, or weakened coil springs, and any steering pull or tracking offset should be investigated immediately. Inspect the sidewalls closely for cracking, perishing, and cuts, particularly on the front pair given the November 2024 advisories for both nearside and offside front tyres. Confirm the age of the tyres through their DOT markings, as high-mileage use combined with age-related rubber degradation could necessitate a full four-tyre replacement regardless of remaining tread. The remainder of the testable mechanical items appear sound on record, with no advisories raised against brake discs, pads, pipes, callipers, suspension arms, or exhaust system across any of the recorded tests. Despite this clean record, the high annual mileage warrants a thorough functional check of the braking system for judder or vibration under heavy pedal application, and a road test over uneven surfaces to detect any knocking, clonking, or excess play that could indicate worn anti-roll bar links or drop links. For the hybrid system specifically, listen for any unusual whine or clunk from the transmission on initial acceleration and deceleration, as the high mileage places greater demand on the planetary gearset and e-drive components. Finally, verify the operation of all registration plate illumination, as the recent failure was caused by an inoperative lamp cluster, and confirm that any replacement has been properly sealed against moisture ingress.
