2012 KIA Sorento 2.2L Diesel · VO12 AAE

The most recent MOT test on the 2012 Kia Sorento occurred on 2026-03-20 and resulted in a passing grade, though it was preceded by two failures in the same period, one of which included a major defect. The pattern of recurring advisories—specifically the corrosion of both offside and nearside front brake pipes, covered in grease—suggests a persistent issue that has not been fully resolved, as these defects were noted in every test since 2024. The presence of a major failure in 2026, particularly the torn constant velocity (CV) boot on the offside front drive shaft, indicates a critical mechanical failure that required immediate attention, likely leading to further wear or potential long-term damage if not addressed promptly. While the latest MOT passed, the history suggests a maintenance trend that has not been consistently stable, with repeated failures pointing to underlying issues that may require thorough investigation before purchase. The vehicle’s recorded mileage of 107,143 miles for a 14-year-old Sorento reflects a moderate annual usage rate of approximately 7,653 miles per year, which is within the expected range for this age and model. However, the absence of service records or a clear pattern of mileage accumulation makes it difficult to determine whether the wear observed aligns with typical usage or if there were periods of prolonged inactivity that exacerbated corrosion or component degradation. Brake pipe corrosion, in particular, is often exacerbated by standing the vehicle in damp conditions or neglecting regular fluid checks, which could explain its persistence. The CV joint boot failure suggests significant drivetrain exposure to contaminants, potentially due to either high-mileage wear or a lack of routine maintenance to replace worn seals or boots. For a prospective buyer, the most critical areas to inspect are the brake system and drivetrain, given the recurring issues. The corroded brake pipes should be thoroughly examined for structural integrity; if they are severely compromised, they may require replacement, as corrosion can lead to brake fluid leaks or even failure under braking. Listen for uneven brake pedal travel or a spongy feel, which may indicate air in the system or failing brake hoses. During a test drive, monitor for any unusual noises from the CV joint area, such as whining or clunking, which could signal further deterioration of the boot or internal seal failure. The brake pedal should be firm and evenly responsive, and the vehicle should not pull to one side under braking, which could indicate misalignment or worn brake components. Additionally, the vehicle’s age and mileage warrant a comprehensive physical inspection. Check the front tyres for signs of sidewall perishing or cracking, which can be a precursor to blowouts, especially if the vehicle has been stored in a dry environment for extended periods. Inspect the battery terminals for corrosion and ensure the 12V system is operational, as older vehicles are more prone to electrical failures due to degraded wiring or a failing alternator. The suspension should be examined for worn bushes, coil springs, or binding calipers, which can lead to clunking noises or uneven ride quality. Finally, verify that all fluids—brake, coolant, and transmission—are topped up and free of contaminants, as fluid degradation over time can accelerate wear on seals and bearings. If the vehicle has been driven regularly, consider checking the service history for oil changes and timing belt replacement, as these are critical for long-term drivetrain health.
