2022 KIA Stonic 2 1.0L Petrol · PF22 XFY

The Kia Stonic’s latest MOT test on 2025-07-16 resulted in a pass, though it followed a failure just two days prior, indicating a critical deterioration in front brake pad thickness that triggered a dangerous failure. The two MOT results reveal a concerning maintenance trend—first a near-critical brake failure with pads down to 1.5 mm on the offside and thinning near the nearside, then a subsequent pass that only addressed worn brake discs and tyres, which were already nearing legal limits. This pattern suggests either inconsistent maintenance or a gradual, progressive wear issue that may have been exacerbated by prolonged standing or aggressive driving. The presence of multiple advisories on brake components and tyres indicates that the vehicle has not been kept in optimal condition, particularly regarding consumable parts that wear out predictably over time. The recorded mileage of 35,995 miles for a 2022 model represents an average of approximately 9,000 miles per year, which is on the higher end for a vehicle of this age but not necessarily alarming if usage patterns were consistent. However, the gap between the two MOT tests—just 15 days apart—may imply either a period of heavy or irregular use, which could accelerate wear on critical components like brakes, tyres, and suspension. If the mileage accumulation was rapid, it could have contributed to the observed brake pad thinning and tyre edge wear, as these issues often correlate with increased braking demands or uneven load distribution. Conversely, if the vehicle stood for extended periods before the second MOT, standing corrosion on brake discs or caliper binding could have further reduced pad life, as moisture and debris can cause rust or seizing in stationary conditions. Given the recurring advisories and failure history, the prospective buyer should prioritise a thorough inspection of the front braking system, focusing on the brake discs, pads, and calipers for signs of uneven wear, corrosion, or binding. During a test drive, listen for abnormal brake noise—such as grinding (indicating metal-to-metal contact) or squeaking (suggesting pad wear or warping)—and check for a firm, even pedal feel without excessive vibration or shuddering, which could signal disc warping or misaligned calipers. Inspect the front tyres closely for uneven wear patterns, such as feathering or cupping, which may indicate suspension or alignment issues, and verify that the tread depth is uniform across the face. If the brake pads are confirmed to be thin but not dangerously so, consider replacing them promptly to prevent further damage to the discs, which can become pitted or grooved from excessive heat and friction. Additionally, check for any fluid leaks around the brake master cylinder or caliper assemblies, as this could indicate failing seals or hydraulic system degradation. Beyond the immediate concerns, the buyer should also address the tyre condition further, as the edge wear suggests either underinflation, excessive load, or misalignment. Measure the remaining tread depth accurately and consider replacing the tyres if they are close to the legal minimum, as worn tyres compromise grip and handling, especially in wet or adverse conditions. For the suspension, visually inspect the front struts and bushes for signs of excessive play or leakage, and listen for clunking noises when driving over bumps, which could indicate worn suspension components or damaged coil springs. Given the vehicle’s age and the observed wear, a service history check is essential—ensure that the manufacturer-recommended fluid changes (e.g., brake fluid, coolant, and transmission fluid) have been conducted at the specified intervals, as fluid degradation over time can lead to system failures or reduced performance. Finally, if the vehicle has been in use for several years, consider a comprehensive inspection of the exhaust system for corrosion or leaks, as well as a check of the 12V battery and starter motor, which can fail silently in older vehicles, particularly if the engine has been left running frequently or the vehicle has been stored in a damp environment.
