2019 KIA Optima 1.6L Diesel · AF69 LMU

The 2019 KIA Optima demonstrates a stable roadworthiness trend over the past two MOT cycles, having passed both the June 2024 and June 2025 tests without defects. The most recent inspection, conducted on 26 June 2025 at 24,695 miles, confirmed no issues, suggesting the vehicle has remained mechanically sound since then. However, the 2023 test cycle reveals a concerning pattern: the car failed on 28 June 2023 at 16,961 miles due to critically low front tyre tread and an inoperative malfunction indicator lamp (MIL). A subsequent retest on 29 June 2023 at 16,964 miles passed, but only after addressing the tyre condition, indicating a rushed or reactive approach to maintenance at that time. The absence of further faults since then implies the MIL issue was resolved, though the tyre tread failures suggest basic upkeep was neglected during that period. The recorded mileage of 24,695 miles over seven years—approximately 3,528 miles annually—is unusually low for a vehicle of this age, particularly given the Optima’s typical usage patterns. The gap between the 2023 failure and the 2024 pass (around 4,194 miles in under a year) stands out as a rapid accumulation, which could imply either intensive use or a period of storage followed by sudden reactivation. The consistency of the mileage thereafter—21,155 to 24,695 miles between June 2024 and June 2025—suggests more stable usage, but the earlier irregularity warrants scrutiny of how the vehicle was stored or driven during that interval. Such low mileage also raises questions about fluid changes, as prolonged inactivity can accelerate degradation in brake fluid, coolant, and transmission oil. A prospective buyer should prioritise an in-person inspection of the front suspension components, particularly the alignment and condition of the front tyres, which failed twice on tread depth in 2023. The irregular tread wear suggests potential wheel imbalance, misalignment, or worn suspension bushes or coil springs, all of which could lead to uneven tyre wear over time. The MIL failure in 2023 indicates past engine-related issues, so the buyer should verify that no further faults have been logged since then and that the vehicle has undergone a full diagnostic check for any unresolved emissions or engine management problems. Additionally, the structural integrity of the wheel arches and sills should be examined for corrosion, as low mileage does not preclude rust development, especially if the vehicle was stored in damp conditions. Finally, the brakes—though not explicitly failed—should be inspected for binding calipers or uneven wear, as the 2023 retest suggests a hasty resolution rather than thorough maintenance.
