2017 KIA Sorento 2.2L Diesel · FJ17 YJT

A pattern of recurring tyre degradation and a recent oil leak advisory defines the mechanical profile of this vehicle, as seen in the latest test passed on 03 February 2026. While the vehicle has maintained a consistent pass record since 2020, the MOT history shows a persistent trend of age-related tyre perishing on the rear axle, with advisories for cracking and damage appearing in 2023, 2025, and again in 2026. The most recent inspection also introduced a new advisory regarding an oil leak near the rear differential around the electric motor unit, marking a shift from purely consumable-based advisories to potential drivetrain seepage. The recorded mileage of 18,301 miles over approximately nine years represents an unusually low usage pattern, averaging roughly 2,033 miles per year. This level of infrequent use is consistent with the age-related perishing noted on the tyres, as rubber components can degrade through ozone exposure and lack of movement even when tread depth remains sufficient. From a mechanical standpoint, such low annual accumulation means that while traditional wear-and-tear components like brake pads or suspension bushes may have low physical wear, other systems may be subject to the effects of long periods of inactivity or limited thermal cycling. Prospective buyers should pay close attention to the rear tyres, as the repeated advisories for cracking and perishing since 2023 suggest the rubber is reaching the end of its structural life regardless of tread depth. During a test drive, inspect the rear tyres for any signs of sidewall bulging or further cracking that could compromise integrity at motorway speeds. Furthermore, the advisory for an oil leak around the rear differential and electric motor unit necessitates a close inspection of the underbody. You should check for any active dripping or heavy accumulation of oil around the rear drive unit and listen for any unusual whining or mechanical noise from the rear end, which could indicate that the leak is related to a seal failure. Beyond the specific advisories, the history of uneven tyre wear on the nearside front in 2021 and 2022 suggests previous issues with wheel alignment or suspension geometry. Although no current advisories exist for the front end, it is prudent to check for any steering pull or unevenness in the tread pattern on the front axle. Given the low mileage and the specific nature of the recent oil leak advisory, ensuring that all seals and fluid levels in the drivetrain are within specification is a necessary step before proceeding with a purchase.
