2017 Hyundai Ioniq 1.6L Hybrid electric (clean) · DN67 TWM

A pattern of rear brake degradation is evident in the recent testing history, culminating in a pass on 30 March 2026 that flagged a worn, pitted, or scored offside rear brake disc. This follows a previous advisory from March 2025 regarding a binding offside rear service brake. While the vehicle has achieved several clean passes since 2023, including a failure in March 2024 for inoperative registration plate lamps that was quickly rectified, the recent focus on the rear braking system indicates a developing mechanical weakness. The recorded mileage of 255,676 miles is exceptionally high for a nine-year-old vehicle, averaging approximately 28,408 miles per year. This usage profile suggests heavy, consistent application, likely involving long-distance travel. Mechanically, this level of accumulation typically results in accelerated wear of the drivetrain, suspension bushings, and wheel bearings, far exceeding the wear seen in average-use vehicles of the same age. A test drive should focus heavily on the rear braking performance to address the recorded binding and disc pitting. Listen for any grinding or scraping sounds from the rear axle and feel for pedal judder or an inconsistent braking response. After a period of driving, a physical check for excessive heat emanating from the offside rear wheel is necessary to determine if the service brake is still binding. Inspection of the nearside front door and rear bumper is required to assess the extent of the recorded damage and ensure there are no underlying structural misalignments. Given the extreme mileage, the buyer should listen for knocks or clunks when driving over speed bumps or uneven road surfaces, which would indicate worn suspension bushes or failing coil springs. Any steering pull or vibration at motorway speeds should be noted as potential evidence of wear in the steering rack or wheel bearings.
