2017 KIA RIO 1.1L Diesel · SP17 HNA

A persistent susceptibility to auxiliary electrical warnings, repeated wiper wear, and an unresolved engine oil leak characterise the testing history of this Kia Rio. While the vehicle successfully passed its test on 1 March 2024, this followed an immediate retest after failing for a malfunctioning tyre pressure monitoring system, ineffective wipers, and an illuminated engine malfunction indicator lamp. Although the diagnostic warning lamp was cleared or repaired alongside the wiper mechanism to secure the pass, the tester retained an active advisory for a non-excessive oil leak. Across its full record, the vehicle has demonstrated periodic roadworthiness failures stemming from basic consumable wear and dashboard warning lights rather than deep-seated structural degradation, though the recurring tyre pressure monitoring warnings across multiple years indicate persistent sensor or wiring vulnerabilities. The recorded odometer reading of 89,992 miles over approximately nine years represents an average accumulation of roughly 10,000 miles per annum, which is consistent with standard UK fleet and domestic usage patterns. This consistent mileage progression means mechanical wear is largely commensurate with age, placing drivetrain ancillaries, friction materials, and chassis hardware at a lifecycle stage where component replacement is routinely required. Prospective purchasers must also account for the extended period elapsed since the March 2024 test, meaning the current condition of wear items and the progression of the recorded oil leak must be verified directly against the physical car rather than relying solely on historic testing data. Physical inspection should focus squarely on the origin and severity of the recorded oil leak. Examine the engine bay and underbody around the camshaft cover gasket, front crankshaft oil seal, and oil sump pan for active fluid weeping, heavy accumulation, or staining that may reach the exhaust manifold or compromise rubber suspension bushes beneath the engine. On the test drive, verify that the engine malfunction indicator lamp illuminates during the ignition pre-check sequence and immediately extinguishes upon starting without lingering or flickering. Connect a diagnostic code reader to interrogate the engine control unit for stored, pending, or recently cleared fault codes, paying close attention to emissions sensors, ignition coils, and oxygen sensors which commonly trigger the engine management light on these petrol and diesel power units. Further checks must address historical chassis and safety items flagged in earlier tests. Inspect the tyre pressure monitoring system to ensure the warning icon does not illuminate after sustained driving, which would indicate failed valve-stem wheel sensors or a control module fault. Although the near-side rear shock absorber was flagged for light oil misting in 2020, check all four corners for signs of fluid weeping, deteriorated bump stops, or floaty rebound over broken road surfaces. Inspect the front brake assemblies for remaining pad thickness and disc lip wear following the 2022 advisory, and ensure that brake pedal application is progressive without judder, sponginess, or lateral steering pull.
