2017 KIA RIO 1.0L Petrol · SP17 NZV

Chronic tyre degradation and recurring brake wear define the mechanical history of this vehicle, culminating in a failure on 17 March 2026 due to dangerous structural tears in both rear tyres. While the vehicle ultimately passed that test, the records show a persistent pattern of tyre perishing and cracking dating back to 2021, alongside a long-term advisory for worn and pitted front inner brake discs that remains present in the latest certificate. The recorded mileage of 47,206 miles is low for a vehicle of this age, averaging approximately 5,245 miles per year. This low annual accumulation is consistent with the MOT history, where tyres were flagged for perishing and cracking over several years despite low tread wear, which typically occurs when vehicles spend extended periods stationary. This usage pattern suggests that rubber components may be degrading due to age rather than operational wear. Attention must be paid to the braking system and steering linkages. The recurring advisories for pitted and scored front inner brake discs suggest surface corrosion that can affect braking efficiency. During a test drive, feel for any pedal judder or vibrations under braking, which would indicate the discs are significantly scored or warped. The recent major failure regarding the nearside front track rod end dust cover should be verified as fully rectified, as a compromised boot allows grit to enter the joint. Listen for any clicking or knocking sounds from the front suspension when turning the steering wheel at low speeds. The persistent mention of engine covers and undertrays preventing full inspections means that the condition of the chassis and lower engine components has not been fully documented by MOT testers for several years. A physical inspection of the underside is necessary to check for corrosion or fluid leaks that may have been obscured. Additionally, while the dangerous tyre failures were addressed for the March 2026 pass, the condition of the remaining tyres should be verified to ensure the entire set has been refreshed, given the history of systemic perishing across all four corners.
