2017 KIA Picanto 1.2L Petrol · SP17 HMK

The defining mechanical story of this 2017 Kia Picanto is a notable escalation in defects across the most recent testing cycle, despite a generally clean earlier history. From 2021 through 2025, the vehicle passed each MOT with only minor advisories related to rear brake disc wear, suggesting steady but acceptable component degradation. The situation changed markedly in early 2026, where a single test produced two dangerous defects for sub-1.6mm tread depth on both front tyres, a major finding for an excessively binding offside rear service brake, a worn offside front lower suspension arm rear bush, and insufficient rear brake lever reserve travel. Although the immediate retest on 1 April 2026 returned a pass with no recorded defects, this cluster of failures indicates that significant wear items were addressed only days before the retest, and the underlying components should not be assumed to be in long-term sound condition. With 84,062 miles recorded over approximately nine years of use, the vehicle has accumulated around 9,340 miles annually, which sits comfortably within the expected range for a small city car of this age. The MOT testing record shows annual attendance from 2021 onwards with no prolonged gaps or off-road periods, which means the mileage accumulation has been consistent rather than the product of a recent long-distance surge or a dormant period followed by a rapid catch-up. Continuous annual use of this nature tends to keep drivetrain seals lubricated and prevents the moisture-related deterioration that affects stationary vehicles, though it does place steady demand on the suspension, braking, and tyre components that have already shown wear in the record. A prospective buyer should focus the pre-purchase inspection on the braking system, given the binding caliper finding and the history of pitted rear brake discs stretching back to 2022. The offside rear caliper that was flagged as binding should be examined for signs of sticking or uneven pad wear, and the handbrake mechanism should be tested on an incline to confirm the reserve travel corrected during the recent repair is holding. The rear brake discs, which have appeared as advisories on two separate tests, may now be approaching a thickness limit and warrant measurement with a micrometer or vernier gauge rather than a visual check alone. Both front tyres were recorded as dangerous on the failed test, meaning replacements were clearly fitted before the retest; confirm that the current tyres are matching brands and sizes, and inspect the sidewalls for any bulges or uneven wear patterns that could point to misalignment or suspension geometry issues. The suspension component flagged as excessively worn on the offside front lower arm rear bush is a specific concern that should be physically inspected by rocking the wheel while applying lateral pressure to detect play, and by listening for clonking noises over uneven surfaces on a test drive. Steering response should be evaluated for any pulling to one side, particularly under braking, which would indicate uneven pad or disc wear rather than a geometry fault. Given that the most recent advisories and failures span braking, suspension, and tyres simultaneously, a raised inspection platform check is advisable to verify the integrity of the front subframe mounting points, brake flexible hoses, and the condition of the rear brake pipework, all of which are common corrosion points on a Picanto of this age and mileage profile.
