2017 KIA Sorento 2.2L Diesel · GV17 AAY

The most recent MOT test on 2026-05-08 resulted in a failure due to an engine malfunction indicated by the Malfunction Indicator Lamp (MIL), which is a critical failure requiring immediate attention. This failure follows a pattern of recurring issues over the past three years, with the previous MOT on 2025-05-08 also failing on major defects such as an improper horn sound and insufficient windscreen washer fluid, alongside a coolant advisory. While earlier MOTs from 2023 to 2025 were largely clean apart from minor and advisory defects, the persistence of engine-related problems suggests underlying wear or a developing mechanical fault that has not been adequately addressed. The vehicle’s roadworthiness is currently compromised by the MIL failure, which could lead to further damage if not rectified promptly, and the presence of other advisories like thin brake pads and worn tyres indicates ongoing maintenance needs that have not been fully resolved. The recorded mileage of 102,726 miles for a 2017 Kia Sorento represents a reasonable annual usage rate of approximately 11,414 miles, which is typical for its age and typical driving conditions in the UK. However, the vehicle’s mileage history does not reveal any extreme gaps or rapid accumulation that would suggest either excessive wear from high-mileage use or prolonged idling, which could exacerbate specific component failures. The absence of significantly higher mileage figures over the past few years implies that the vehicle has been driven consistently but not excessively, which is generally favourable for maintaining structural and mechanical integrity. Nevertheless, the combination of moderate mileage with recurring engine issues and wear-related advisories indicates that the vehicle has been subjected to some degree of stress, particularly in the drivetrain and suspension systems, warranting thorough inspection to identify any cumulative wear or latent faults. Given the recent MOT failure due to the engine MIL and the history of advisory defects, the prospective buyer should prioritise a comprehensive mechanical inspection to diagnose and rectify the underlying engine problem. The presence of a Malfunction Indicator Lamp typically points to a failing sensor, a failing injectors, a faulty spark plug, or a more serious issue such as a camshaft or crankshaft sensor failure. Symptoms to watch for during a test drive include rough idling, misfires, loss of power, or a noticeable delay in acceleration, which may indicate a failing fuel system or ignition component. Additionally, the vehicle’s coolant advisory from previous MOTs suggests potential overheating risks, so checking for coolant leaks under the bonnet and ensuring the radiator and water pump are functioning correctly is essential. The thin brake pads from the 2024 MOT indicate that the braking system is approaching critical wear, and the buyer should inspect brake pad thickness, disc warping, and caliper binding during the inspection. Listen for uneven brake noise or shuddering during braking, which could signal warped discs or contaminated brake fluid. For the buyer’s practical inspection, focus on the vehicle’s suspension and tyre condition, as these areas have shown recurring advisories over the years. The rear tyres have exhibited signs of wear close to legal limits and minor cracking, which could indicate underinflation, excessive load, or prolonged standing in one position. Inspect the tyre sidewall for signs of perishing, which is more likely to occur in older vehicles due to exposure to UV light and temperature fluctuations. Check the tyre pressure and tread depth, ensuring they meet the legal minimum of 1.6mm across the central 3/4 of the tread and that the tyres are balanced and aligned correctly to prevent uneven wear. The front tyres also show wear close to legal limits, so a thorough tread check and visual inspection for damage or separation are necessary. Additionally, the buyer should verify the vehicle’s 12V battery health, as prolonged idling or standing can lead to battery corrosion or discharge, particularly in older vehicles. Check the battery terminals for signs of corrosion, and test the battery’s charge and voltage to ensure it is capable of supporting the engine’s electrical demands. Finally, given the vehicle’s age and the history of fluid-related advisories, consider checking the condition of the engine oil, coolant, and brake fluid for any signs of degradation or contamination, as these fluids can break down over time even without significant mileage. A service history check for scheduled fluid changes and component replacements would also provide valuable insight into the vehicle’s maintenance record.
