2018 Hyundai Ioniq 1.6L Hybrid electric (clean) · SC18 SZX

The most recent MOT test for this Hyundai Ioniq was passed on 18 September 2025, following a failure on the preceding day. The failure was caused by a major defect regarding headlamp lens discoloration and a minor defect involving a deteriorated offside front constant velocity boot. While the vehicle currently holds a clean MOT certificate, the sudden appearance of these defects after a period of defect-free testing indicates that the vehicle is entering a stage of its lifecycle where mechanical consumables are reaching the end of their effective service life. This suggests a shift from a period of stability to one requiring more vigilant maintenance of wear-related components. The recorded mileage of 147,836 miles over approximately eight years represents a high annual usage rate of roughly 18,480 miles. This level of mileage is significantly above the UK average and implies heavy, consistent use. While high-mileage vehicles that have been driven primarily on motorways can often be in better mechanical condition than those used for short urban trips, the sheer volume of mileage will have accelerated the wear on the suspension, braking system, and drivetrain. You should approach the inspection with the expectation that components such as suspension bushes, coil springs, and shock absorbers may be nearing the end of their operational life. When conducting your test drive, pay close attention to the recent CV boot failure. Ensure the offside front drive shaft has been properly addressed and check for any rhythmic clicking or popping noises when turning the steering wheel at low speeds, which would indicate a failing CV joint. Furthermore, inspect the headlamp lenses to ensure the previous discoloration issue has been corrected and does not impair nighttime visibility. Given the high mileage, you must also check the brake discs for significant scoring or lip formation and listen for any signs of binding calipers or shuddering during braking maneuvers. Finally, inspect the tyres for uneven wear patterns that could suggest worn suspension geometry or tracking issues. Because of the high annual mileage, it is essential to verify the service history to ensure that oil changes and fluid replacements, such as brake fluid and coolant, have been performed at the correct intervals rather than just at MOT intervals. Check the vehicle's underside for any evidence of fluid leaks from the drivetrain or excessive corrosion, as high-use vehicles are more prone to these issues. Verifying that the service book contains regular, timely stamps is critical to confirming that this high-mileage vehicle has been adequately maintained.
