2016 KIA Sorento 2.2L Diesel · FD65 WFN

The most recent MOT test on 2026-02-13 resulted in a failure, with the vehicle retaining multiple critical advisories and a persistent engine malfunction indicated by the MIL (Malfunction Indicator Lamp) remaining active. This failure follows a pattern of recurring issues, particularly with brake components and suspension ball joints, which have been flagged in nearly every MOT test since 2022. While some tests have shown passing results, the advisories—particularly the thin brake pads and play in the front suspension arm ball joints—have persisted or worsened, suggesting a lack of timely maintenance. The presence of a persistent engine fault further complicates the vehicle’s roadworthiness, as this could indicate deeper mechanical issues that may not be immediately visible but could escalate into costly repairs if ignored. The trend here is clearly one of unresolved wear and potential underlying problems, rather than a stable or improving condition. The recorded mileage of 77,598 miles for a 2016 Kia Sorento represents a moderate but not exceptional usage rate, averaging around 7,760 miles annually—a figure that aligns reasonably with typical driving patterns for this age group. However, the consistency of the mileage suggests a steady but not particularly aggressive driving regimen, which might imply that wear has accumulated gradually rather than rapidly. The absence of significant mileage spikes or long periods of inactivity does not necessarily indicate excessive stress on components, but it also means that consumables like brake pads and suspension bushings have been subjected to consistent, albeit moderate, usage. The rear differential leak, noted in multiple MOTs, could be exacerbated by this steady mileage, as differential seals degrade over time regardless of driving intensity, potentially leading to oil loss and increased wear on the gears. Given the recurring advisories and engine fault, the buyer should prioritise a thorough inspection of the brake system, suspension, and drivetrain components. During a test drive, listen for unusual noises such as grinding when braking (indicating worn pads or warped discs) or clunks or rattles from the suspension, which could signal failing ball joints or loose suspension arms. Check for uneven tyre wear patterns, particularly on the inner edges of the rear tyres, which may suggest misalignment or suspension issues contributing to the MOT advisories. Inspect the brake discs for scoring, pitting, or excessive thickness reduction, and verify that the pads are not only thin but also evenly spaced to ensure proper operation. The persistent MIL should prompt a diagnostic check of the engine control unit and related sensors, as the fault could stem from a failing oxygen sensor, wiring issue, or more complex engine management problem. If the engine fault cannot be resolved, the vehicle’s roadworthiness may remain compromised until addressed. For the buyer, given the vehicle’s age and the history of wear-related advisories, a comprehensive pre-purchase inspection is strongly advised. Focus on the suspension arms, particularly the ball joints, which show consistent slight play across multiple tests—this could lead to steering instability or premature wear if not serviced. The brake system, especially the pads and discs, should be replaced according to the advisories to prevent reduced braking performance or failure. The rear differential leak necessitates immediate attention to avoid further oil loss and potential gear damage, as differentials are critical to drivetrain integrity. Additionally, check for signs of fluid degradation in the engine oil, transmission fluid, and coolant, as these fluids should be replaced at manufacturer-recommended intervals, even if the vehicle has not been driven excessively. For the tyres, despite the recent MOT noting wear close to the legal limit, consider replacing them to avoid safety risks and ensure optimal grip, especially given the vehicle’s age and the potential for further wear from the suspension issues. Finally, verify that the service history is up to date, particularly for the suspension components and brake system, to ensure no further wear has been overlooked.
