2016 KIA Sorento 2.2L Diesel · FN16 TYY

The latest MOT test for this 2016 Kia Sorento on 2026-01-28 resulted in a pass, though it came with two critical advisories regarding nearside and offside rear brake pads wearing thin, both classified under 1.1.13(a)(ii). Comparing this to the previous MOT failures in 2024 and 2025, the trend is not improving—rather, it reflects a persistent and concerning issue with brake pad wear that has persisted through multiple tests. The earlier failure in 2025 highlighted front brake pads reaching the dangerous threshold of 1.5 mm thickness, indicating that the rear pads are now also approaching critical levels of wear, which could compromise braking performance if not addressed promptly. The fact that the vehicle has passed MOTs in 2022 and 2021 without such advisories suggests that either the brake system has been subject to intermittent or delayed maintenance or that the wear progression has been more gradual than initially suggested. The presence of multiple advisories on brake components in close succession underscores the need for immediate attention to prevent potential failure during critical braking events. The recorded mileage of 43,625 miles for a vehicle aged ten years is notably low, translating to approximately 4,362 miles per year—a rate that is significantly below the average for its class and age. Such low mileage can result from lighter usage, extended periods of stationary storage, or a combination of both, which may contribute to accelerated wear in certain systems. However, the absence of significant mileage accumulation over the last few years could also suggest that the vehicle has been kept in a relatively pristine condition, though this must be balanced against the persistent brake wear issues. For example, standing for prolonged periods can lead to brake disc corrosion, caliper binding, or warping, particularly if the pads are not regularly replaced. Additionally, low mileage may mask other wear patterns, such as suspension or drivetrain components that could be degrading more subtly due to reduced dynamic loading. Given the recurring advisories on brake pad wear and the critical failures from previous MOTs, the prospective buyer should prioritise a thorough inspection of the braking system. During a test drive, listen for unusual noises such as grinding, squeaking, or scraping from the rear brakes, which could indicate pad-to-disc contact or impending failure. Inspect the rear brake discs for signs of glazing, warping, or excessive heat discolouration, as these can reduce braking efficiency. Check for any fluid leaks around the brake calipers or master cylinder, which may signal hydraulic system issues. The rear brake pads should be visually inspected for remaining thickness—if they are below 1.5 mm, they must be replaced immediately, as this is the legal minimum for safety. Additionally, verify that the rear brake shoes or linings (if applicable) are not also worn thin, as this could exacerbate the problem. Given the history of front brake failures, the buyer should also ensure that the front brake pads are within safe limits and that the discs are free from binding or corrosion. Beyond the immediate brake concerns, the buyer should conduct a broader inspection of the vehicle’s structural and functional components. Given the low mileage and potential prolonged stationary periods, check for signs of corrosion on the undercarriage, particularly around the wheel arches, exhaust system, and underbody seals, which can degrade over time even with minimal movement. Inspect the tyre tread depth thoroughly, as the 2022 advisories on front tyres being worn close to the legal limit suggest that further wear may have occurred since then. Look for uneven tread wear patterns, which could indicate misalignment or suspension issues, and check for sidewall cracks or perishing, which can compromise tyre integrity. The suspension advisories from 2022 regarding slight play in the front lower suspension arm ball joints should be addressed, as excessive play can lead to poor handling, uneven tyre wear, and potential suspension failure. Test the vehicle’s handling by driving at various speeds and noting any clunking noises from the suspension or steering components, which may indicate worn bushes or damaged springs. Finally, verify that the vehicle’s service records are up to date, particularly for fluid servicing—such as brake fluid, coolant, and transmission fluid—since these degrade over time regardless of mileage. A 12V battery health check is also advisable, as prolonged inactivity can lead to weak or dead batteries, which may fail to provide adequate power to critical systems.
