2018 Hyundai Ioniq 1.6L Hybrid electric · EF18 WTU

Recurring issues with rear brake disc condition represent the most consistent mechanical trend for this vehicle, appearing as advisories in both June 2023 and again in the most recent test on 03 June 2026. While the vehicle has passed its inspections since 2021, the presence of these repeated advisories regarding pitted or scored rear brake discs suggests a persistent pattern of wear or surface degradation on these components. The testing history also shows instances of dangerous failures related to tyre tread depth in 2022 and 2023, though these were rectified to achieve subsequent passes. The vehicle has covered 125,807 miles over its eight-year lifespan, which equates to an average annual usage of approximately 15,726 miles. This represents a higher-than-average mileage accumulation for a 2018 model, indicating consistent long-distance or high-frequency road use. From a mechanical perspective, this sustained mileage increases the likelihood of accelerated wear on consumable items such as suspension bushes, brake pads, and various drivetrain components, which should be closely monitored alongside the recorded brake disc issues. A prospective buyer should pay particular attention to the braking system during a test drive. Given the repeated advisories for worn, pitted, or scored rear brake discs, it is essential to check for any pulsation or judder through the brake pedal when applying pressure, as well as any unusual grinding noises from the rear of the vehicle. The presence of scoring can sometimes lead to uneven braking performance or binding calipers, so the smoothness of the deceleration process is a critical metric for this specific car. Beyond the braking system, the history of tyre tread depth failures necessitates a thorough inspection of the current tyre condition across all four corners. While the 2025 advisory noted a tyre pressure light, the primary focus should remain on the physical integrity of the rubber and the remaining tread depth. During the test drive, listen for any rhythmic thumping or uneven road noise that might indicate irregular tyre wear, and check the steering for any pulling or instability that could stem from the higher mileage accumulation on the steering and suspension assemblies.
