2012 KIA Sorento 2.2L Diesel · R80 AAM

The 2012 Kia Sorento’s latest MOT test on 2026-06-29 resulted in a passing grade, though it included two advisories that warrant careful attention. The overall maintenance trend over the past four years is mixed, with two failed MOTs in 2024 and 2025 indicating recurring issues that suggest either underlying wear progression or potential neglect in addressing prior defects. The most critical failures—particularly the dangerous brake pad condition in 2025 and the brake performance test failure in 2024—highlight a pattern of brake system degradation that must be addressed promptly to prevent safety risks. While the vehicle has passed subsequent tests, the presence of advisories on corroded sub-frames and suspension components suggests structural and mechanical fatigue that could escalate without intervention. The vehicle’s recorded mileage of 149,169 miles at 14 years old represents a moderate annual usage rate of approximately 10,655 miles per year, which is within the expected range for a car of this age and class. However, the lack of a service history or clear mileage gaps between MOTs could imply either inconsistent maintenance or prolonged periods of inactivity, which may have exacerbated wear in certain systems. For example, standing vehicles can develop corrosion in brake components, caliper binding, and suspension linkages due to moisture exposure, while fluid degradation—particularly in the hydraulic brake system—can accelerate if not serviced regularly. The high mileage also implies significant wear on consumables like brake pads, tyres, and suspension bushes, necessitating a thorough inspection of these components to assess their remaining service life. To proceed with a purchase, the prospective buyer should conduct a meticulous physical inspection and test drive to confirm the absence of the issues flagged in the MOT history. Focus on the brake system first: listen for uneven brake pedal travel or a spongy feel, which may indicate air in the hydraulic system or worn brake lines. Check for brake disc warping, scoring, or excessive thickness loss beyond the 1.5mm minimum, and inspect the calipers for binding or excessive play. The rear sub-frame corrosion advisories suggest the vehicle may have standing corrosion in the lower structural components, so visually inspect the sub-frame and suspension arms for cracks or severe pitting, particularly near the wheel wells. During the test drive, note any clunking noises from the suspension, especially when transitioning between rough and smooth surfaces, which could indicate worn suspension bushes or ball joints. Additionally, verify that the parking brake engages smoothly and that the rear brake pads are not excessively worn or glazed. For the tyre condition, the advisories from 2024 and 2025 indicate that the tyres are nearing or have exceeded the legal minimum tread depth on certain edges, which could compromise traction and wet-weather performance. Inspect the tyres for sidewall cracking or perishing, which is more likely with age than mileage, and check for uneven wear patterns that may signal misalignment or suspension issues. A thorough check of the exhaust system for leaks or excessive noise is also prudent, as the vehicle’s age and mileage could contribute to carbon buildup or minor exhaust component wear. Finally, given the vehicle’s age and the lack of a service history, prioritise checking the 12V battery for capacity and ensuring all electrical systems are functioning, as older batteries may struggle with prolonged periods of inactivity. Time-based fluid servicing—such as brake fluid, coolant, and transmission fluid—should be addressed within the next 12 months to mitigate potential degradation from age-related breakdowns.
