2017 Hyundai Tucson 1.6L Petrol · RO67 AAE

A pattern of critical safety failures regarding tyres and braking components defines the recent mechanical history of this vehicle, despite a clean pass recorded on 27 November 2025. The testing trend shows significant volatility, with the 2025 inspection resulting in a failure for dangerous tyre tread depths on both the offside front and nearside front, alongside an exhaust emissions failure due to excessive carbon monoxide levels. This follows a 2024 failure where the rear inner brake pads were recorded as being below the 1.5mm legal limit, which was also classified as a dangerous defect. While the most recent test shows no defects, the frequency of these high-risk failures suggests a history of components being operated at the absolute limit of their legal and safe tolerances. The vehicle has covered 78,628 miles over approximately nine years, averaging roughly 8,736 miles per year. This mileage accumulation is consistent with typical UK usage for a vehicle of this age and does not suggest either excessive heavy-duty use or long periods of stationary storage. From a mechanical standpoint, this steady rate of use implies that wear on consumable items such as brake pads, tyres, and exhaust systems should follow a predictable lifecycle, yet the MOT record indicates that these components have frequently reached critical failure points before being addressed. Prospective buyers should pay close attention to the braking system and tyre condition during a physical inspection and test drive. Given the previous dangerous failures for thin brake pads, it is essential to check for any signs of brake disc scoring or uneven wear. During the test drive, listen for any grinding noises during deceleration and feel for any pedal judder or pulling to one side, which could indicate binding calipers or uneven pad wear. The history of near-legal tyre tread depths and cracking on the nearside rear tyre suggests that the rubber integrity and tread depth should be scrutinised across all four corners to ensure they are not nearing the 1.6mm limit or showing signs of sidewall perishing. The recorded failure for high carbon monoxide emissions in late 2025 warrants a careful observation of engine performance. While the vehicle passed the subsequent test, any hesitation during acceleration, irregular idling, or a noticeable change in exhaust note could be indicative of underlying issues with the combustion process or the catalytic converter. Ensuring the exhaust system is free from leaks and that the engine reaches operating temperature smoothly will be important, as the previous emissions failure points to a specific instance where the engine's ability to manage fuel-to-air ratios was outside of manufacturer specifications.
