2015 KIA Soul 1.6L Diesel · FG15 XDE

The 2015 KIA Soul’s most recent MOT test on 26 June 2025 at 33,080 miles passed without defects, confirming it remains roadworthy for the next year. However, the preceding test in June 2024 at 30,155 miles revealed two notable issues: the offside rear brake pipe exhibited corrosion and contamination at the flexi joint, while the front brake pads were classified as "wearing thin." These findings suggest a minor but persistent trend in brake system maintenance, particularly on the rear axle. The absence of further brake-related advisories in later tests implies the issues were addressed, but the 2024 corrosion on the brake pipe warrants scrutiny—flexi joints are prone to leaks if not properly sealed or lubricated. No other recurring faults appear in the record, though the clean slate of recent tests does not guarantee hidden wear. The vehicle’s mileage progression of roughly 3,007 miles per year over the past decade is unusually low for its age, indicating either infrequent use or prolonged periods of storage. Between the 2021 and 2022 tests, the mileage increased by just 2,708 miles over 11 months, while the gap between 2024 and 2025 saw a slightly higher but still modest rise of 2,925 miles. Such low annual mileage can lead to stagnant fluid conditions—brake fluid, coolant, and fuel—while suspension components may stiffen from disuse. The lack of intermediate MOTs or service records means there’s no confirmation of regular fluid changes or suspension servicing, which are critical for vehicles with limited movement. A buyer should prioritise an immediate inspection of the rear brake flexi joint and pipe for corrosion or leaks, particularly on the offside, as the 2024 advisory suggests this area may require attention. The front brake pads, though not currently failing, were flagged as thin in 2024, so their remaining thickness should be verified—uneven wear could indicate binding calipers or misaligned wheels. Given the low mileage, the suspension bushes and coil springs should be checked for stiffness or cracking, especially if the vehicle has spent extended periods stationary. Tyre tread depth and lateral wear patterns are also essential to review, as the absence of tyre-related advisories in recent tests does not preclude uneven wear from past neglect. Finally, the underbody should be examined for corrosion, particularly around the wheel arches and sills, where rust can compromise structural integrity over time.
