2014 KIA Optima 1.7L Diesel · LC14 EBD

The vehicle remains roadworthy but the maintenance record shows a worsening trend regarding structural integrity and mechanical component wear. The most recent test in September 2025 at 183,969 miles flagged multiple advisories including play in the nearside front anti-roll bar linkage and oil misting on the rear shock absorbers. While the car continues to pass, the persistence of corrosion-related issues and marginal performance on the parking brake suggests that the vehicle is entering a stage where age-related degradation is no longer being proactively addressed. At 183,969 miles, this 12-year-old Optima reflects high mileage, averaging over 15,000 miles per year. There is a significant jump in usage recorded between 2021 and 2024, where the vehicle covered over 24,000 miles in just three years. This high-frequency use explains the accelerated wear on the suspension and braking systems. The gap between the 2021 and 2023 tests shows a period of lower usage before the current high-intensity cycle resumed. A buyer must conduct a thorough inspection of the underbody, specifically focusing on the rear sub-frame and brake pipes. The record notes corrosion on the sub-frame in 2024, which persisted as general underbody corrosion into 2025; if surface rust is progressing, it will eventually lead to a structural failure. The parking brake has only just met the efficiency threshold in both 2023 and 2025, indicating the mechanism or cables are reaching the end of their functional life. Furthermore, recurring issues with ball joints and shock absorbers indicate that the front and rear suspension assemblies will require imminent replacement to maintain vehicle handling and safety.
