2018 KIA Optima 1.7L Diesel · ND67 UNF

The 2018 KIA Optima’s most recent MOT tests, conducted on 2025-10-11 at 181,931 miles, reveal a concerning pattern of repeated failures despite no recorded defects. This anomaly—two simultaneous pass and fail entries—suggests either a clerical error or a deliberate attempt to bypass inspection, though the absence of defects on both attempts is unusual. The preceding test in September 2024 at 157,802 miles also shows identical pass/fail duplication, reinforcing suspicion of irregularity rather than genuine mechanical issues. Without independent verification, this history casts doubt on the vehicle’s true condition, as it fails to demonstrate consistent compliance with UK roadworthiness standards. The recorded mileage of 181,931 miles over eight years equates to an average of 22,741 miles annually, a rate significantly higher than the UK average for vehicles of this age. The gap between tests—approximately 12 months between 2023 and 2024, and again between 2024 and 2025—aligns with the legal requirement but does not account for the abrupt mileage jump from 133,360 to 157,802 miles between September 2023 and September 2024, a 24,442-mile increase in under a year. Such rapid accumulation suggests either intensive use or potential odometer manipulation, though the latter cannot be confirmed without further evidence. The lack of advisories or defects in any test implies no formal warnings were issued for wear items like suspension bushes or brake components, though this does not preclude hidden deterioration. Given the irregular MOT history, a prospective buyer should prioritise an independent inspection of high-wear components, particularly the suspension system—coil springs, bushes, and shock absorbers—given the high mileage. The brakes, though not explicitly flagged, warrant scrutiny for uneven wear or binding calipers, especially if the vehicle has been driven aggressively. Structural integrity should also be assessed for corrosion, particularly around wheel arches, sills, and the subframe, as prolonged high-mileage use increases vulnerability. The absence of advisories does not guarantee these areas are sound, and visual inspection or a detailed mechanical check is essential to verify their condition. The repeated pass/fail entries demand transparency from the seller regarding any unresolved issues or maintenance gaps.
