2017 KIA Optima 1.7L Diesel · RF66 BYB

The most recent MOT test on the 2017 Kia Optima occurred on 2026-04-27, resulting in a passing grade. However, the preceding test on 2026-04-22 resulted in a failure due to critical issues with the front anti-roll bar ball joint dust covers, which no longer effectively prevent dirt ingress, and a major failure related to the front windscreen washer system. While the vehicle has passed subsequent tests since, the recurring advisories on tyre wear—particularly nearside rear tyres worn close to the legal limit and showing edge wear—suggest a pattern of gradual but persistent tyre degradation. The presence of a nearside rear tyre nail further indicates either previous punctures or excessive road debris exposure, which could accelerate tyre failure if not addressed promptly. This trend indicates that while the vehicle has maintained roadworthiness, the maintenance history reveals a need for closer attention to tyre management and suspension component integrity. The recorded mileage of 64,466 miles for a vehicle aged nine years represents a moderate annual usage rate of approximately 7,163 miles per annum, which is consistent with typical driving patterns for this model. Such mileage does not necessarily indicate excessive wear, but it does imply that the vehicle has accumulated significant usage over time, particularly in the suspension, braking, and tyre systems. The lack of substantial mileage gaps suggests consistent operation, but the wear patterns observed in the MOT history—such as tyre edge wear and potential brake pad thinning—could be exacerbated by prolonged periods of high-speed driving or aggressive cornering. Additionally, while the mileage is not exceptionally high, the combination of age and repeated tyre advisories may warrant a more thorough inspection of tyre sidewall integrity, including signs of cracking or perishing, which can become critical over time even at moderate mileages. Given the MOT history, the prospective buyer should conduct a comprehensive inspection focusing on the suspension and braking systems. The recurring anti-roll bar ball joint dust cover failures indicate that the upper control arm joints are compromised, leading to potential play and reduced stability. During a test drive, listen for unusual clunking or rattling noises from the front suspension, especially when transitioning between rough and smooth surfaces, as this may signal worn bushings or binding joints. Inspect the anti-roll bars for signs of bending or excessive wear, and verify that the ball joints remain aligned and free from excessive play. The brake system should be checked for any signs of binding calipers, uneven disc wear, or corrosion, particularly on the nearside front brake discs, which were previously noted as dangerously thin. A thorough brake inspection should include checking for brake fluid leaks, ensuring the hydraulic system operates smoothly, and confirming that the brake pedal does not feel spongy or require excessive force. For tyres, the buyer should examine the entire tread profile for consistent wear patterns, as the advisories suggest that the nearside rear tyre is particularly vulnerable. Look for signs of uneven wear, which could indicate misalignment or suspension issues, and inspect the sidewall for any cracks, bulges, or signs of perishing, which may compromise tyre integrity. Given the age of the tyres and the repeated advisories, consider replacing them if they approach or exceed the legal minimum tread depth, as worn tyres pose a significant safety risk. Additionally, check for any embedded nails or sharp objects that may have penetrated the tyre, which could lead to future blowouts. Beyond the mechanical checks, the buyer should verify the condition of the 12-volt battery, as prolonged periods of inactivity or high mileage can lead to diminished capacity or corrosion in the terminals. Finally, since the vehicle has not undergone a full fluid service within the manufacturer’s recommended intervals, inspect the engine oil, coolant, and brake fluid for signs of degradation or contamination, and consider a top-up or replacement if necessary, particularly given the age of the vehicle.
