2014 KIA Optima 1.7L Diesel · SA64 RFN

The most recent DVSA examination on 3 April 2026 resulted in a pass, though the tester recorded advisories concerning corrosion on both the nearside and offside brake pipes running front to rear, noting they are covered in grease or other material which masks the pipe condition. Reviewing the broader MOT history, the maintenance trend appears largely stable with no outright failures since 2022, but a clear pattern of recurring brake-related advisories has emerged across multiple test cycles. Front brake disc wear and pitting has been flagged in 2020, 2022 and inferred from the fluctuating brake efficiency advisory in 2024, suggesting progressive wear on the front braking system that has not yet resulted in a failure but warrants close attention. Additionally, a nearside front anti-roll bar linkage ball joint with slight play was noted in 2021 and again in 2022, indicating a component that has been deteriorating gradually rather than being resolved. With 86,643 miles recorded on a 2014 vehicle, this Optima has covered approximately 7,220 miles annually, which is broadly typical for its age and suggests regular if not particularly heavy use. There are no significant gaps in the MOT record indicating long periods off the road, which is positive from a standing-corrosion perspective, although the accumulated mileage places the vehicle squarely in the zone where major consumables such as suspension bushes, coil springs, brake discs and flexible brake hoses begin to require close inspection. The brake pipe corrosion advisories are a notable concern for a vehicle of this age and mileage, as under-bonnet and underbody brake lines are susceptible to surface corrosion particularly in areas where road salt accumulates during winter months. Given the recurring brake and suspension advisories, a prospective buyer should prioritise a thorough physical inspection of the front braking system, including measurement of brake disc thickness to determine remaining service life, and a check of the flexible brake hoses for cracking or bulging. The anti-roll bar linkage wear can be evaluated by pushing laterally on the front corners of the vehicle when unweighted to feel for clonks or excessive free play, and on a test drive any knocking or rattling over uneven surfaces should be noted as a sign that the bushes or links require replacement. Brake pipe corrosion should be examined closely underneath the vehicle to assess whether the protective coating has simply been applied over early surface oxidation or whether deeper structural corrosion is present, as brake line replacement is a safety-critical and potentially costly repair. Beyond the recorded advisories, age-related checks remain highly relevant for a 12-year-old vehicle regardless of mileage. Tyre sidewalls should be inspected for perishing or cracking from UV exposure, particularly as the rear tyres were flagged for this in 2022, and the 12V battery should be load-tested as units of this age commonly fail without warning. Coolant, brake fluid and automatic transmission fluid if applicable degrade by calendar age rather than mileage alone, so evidence of recent fluid changes should be sought in the service history. Finally, the underside should be examined for exhaust hanger integrity, catalytic converter security which is a known theft target, and any signs of fluid weeping from the engine or transmission, as these items often only become apparent on close inspection rather than during a standard road test.
