2015 KIA Sorento 2.2L Diesel · YS64 OXL

A recent history of exhaust-related failures and emissions issues defines the mechanical profile of this vehicle, most notably seen in the January 2026 failure regarding a major rear exhaust gas leak. While the vehicle passed its most recent test on 21 January 2026, the preceding failure indicates a significant breakdown in the integrity of the exhaust system that required rectification. This follows a period of relatively clean results in 2024 and 2025, but the recurrence of electrical issues, such as the rear fog lamp failure in early 2024, suggests that specific peripheral components have required attention over the last few years. The recorded mileage of 58,716 miles for an 11-year-old vehicle represents a low annual average of approximately 5,338 miles. This usage pattern suggests the vehicle has been driven significantly less than the UK average, which can often mean less wear on high-friction components like the engine and gearbox. However, such low annual accumulation can also lead to different mechanical considerations, such as the degradation of rubber components or tyres through age rather than tread wear, a factor previously noted in the 2021 advisory regarding perished rear tyres. Prospective buyers should pay close attention to the exhaust system and emissions performance during a test drive. Given the major failure in January 2026, it is essential to listen for any unusual droning, bubbling, or loud rasping sounds coming from beneath the chassis, particularly during acceleration or when the engine is under load, which could indicate a poorly sealed joint or a developing leak. Additionally, because emissions testing was previously unable to be completed due to the leak, the engine's idling stability and smoothness should be monitored to ensure no residual issues remain from the exhaust system's failure to meet standards. Further inspection should focus on the braking system and electrical peripherals. The 2021 advisory for low rear brake pads indicates that consumable wear has been a factor in the past, so the driver should check for any pedal pulsation or grinding noises when applying the brakes. Regarding the electrical history, specifically the rear fog lamp issues, a thorough check of all exterior lighting and the functionality of the rear fog lamp is necessary to ensure the previous major failure has been fully resolved. Finally, while the 2026 advisory regarding a child seat was a procedural matter, ensure that all seatbelt mechanisms operate smoothly and without obstruction.
