2017 KIA Optima 1.7L Diesel · GK67 KNL

The vehicle remains roadworthy, but the maintenance trend shows a concerning pattern of reactive rather than preventative care. The most recent test in September 2025 at 128,132 miles highlighted a persistent engine rattle and critical tyre conditions across all four wheels reaching the legal tread limit. While the car passed, the recurring nature of tyre wear and feathering suggests a long-term alignment issue or suspension geometry that has not been professionally addressed over multiple years. At 128,132 miles, this nine-year-old Kia has covered an average of over 14,000 miles per year. The mileage data shows consistent high-frequency usage, with a 15,798-mile interval recorded between the September 2024 and September 2025 tests. This high rate of accumulation places significant stress on drivetrain components and suspension bushings, which is evidenced by the 2024 advisory regarding worn lower suspension arm bushes on both the nearside and offside front corners. A buyer must inspect the front suspension geometry closely, as the tester flagged worn bushes in 2024 that likely contributed to the rapid uneven tyre wear noted in 2025. The persistent engine rattle mentioned in both 2024 and 2025 requires a mechanical diagnostic check to rule out timing chain stretch or internal engine component wear. Furthermore, the 2022 failure due to thin brake pads and the consistent history of bald tyres indicate that previous owners frequently neglected consumable items until they reached failure points, necessitating a thorough inspection of the current brake discs, calipers, and tyre quality.
