2014 KIA Optima 1.7L Diesel · LB63 GLJ

The 2014 Kia Optima presents a concerning maintenance trajectory, as the recent MOT history indicates a pattern of recurring braking system deficiencies and structural wear. While the vehicle passed its most recent test in February 2026, the preceding failure in the same month highlighted significant issues including an excessively corroded brake pipe, a compromised anti-roll bar dust cover, and inadequate parking brake efficiency. The fact that the parking brake and general service brake performance have been flagged as advisories or failure points across multiple consecutive years suggests that the braking system has been subject to persistent neglect or underlying mechanical degradation that may not have been fully rectified during previous service intervals. With a recorded mileage of 122,881 miles over twelve years, the vehicle has seen consistent annual usage of approximately 10,240 miles. This is a standard mileage profile for a vehicle of this age, indicating it has not spent prolonged periods standing idle, which generally helps prevent the premature seizure of brake calipers or the perishing of rubber components often associated with low-mileage examples. However, the high cumulative mileage means that major drivetrain and suspension components are now entering a phase where fatigue is expected. Prospective buyers should assume that the vehicle has been driven regularly and that the current condition is a reflection of ongoing wear and tear rather than storage-related issues. During your test drive, pay close attention to the braking performance, as the history of parking brake inefficiencies and fluctuating service brake readings suggests potential issues with seized caliper sliders, binding mechanisms, or degraded brake fluid. Listen carefully for any clunking or knocking noises from the front suspension when travelling over uneven surfaces, which would indicate that the previously repaired or worn anti-roll bar and track rod components are again failing. You should also check for any dashboard warning lights, specifically regarding the electronic stability control system, which was previously identified as a failure point. Ensure the pedal feel is firm and progressive, as any sponginess or pulling to one side during braking could indicate that the historical corrosion issues were not addressed with long-term repairs. Beyond the mechanical operation, a thorough physical inspection of the underside is essential due to the documented history of brake pipe corrosion. You should look for signs of heavy underseal application, which is sometimes used to mask surface rust on fuel or brake lines. Check the condition of all four coil springs for signs of snapping or recent replacement, as the offside rear spring failure in 2025 suggests the suspension has been under significant stress. Finally, verify the service history to confirm that the brake fluid has been changed according to the manufacturer schedule, as moisture ingress in older fluid is a common cause of the internal corrosion and binding issues seen in this vehicle's MOT record.
