2017 Hyundai Tucson 1.6L Petrol · ST67 CWD

Recurring issues with the parking brake system and emerging underbody corrosion define the mechanical profile of this vehicle, suggesting a trend of deteriorating braking efficiency. While the car achieved a pass on 2026-07-28, this followed a failure for insufficient parking brake efficiency, a defect that also appeared during the 2025 testing cycle. The presence of underbody corrosion and worn rear brake discs in the most recent records indicates that the chassis and braking hardware are now entering a phase of significant wear. With 91,844 miles recorded over approximately nine years, the vehicle has averaged around 10,200 miles annually, which is consistent with typical UK usage for this class of SUV. This steady accumulation of mileage means that high-wear consumables and drivetrain components have been subjected to regular, moderate stress. At this mileage threshold, it is common to see the onset of suspension bush degradation and the need for comprehensive brake system overhauls, both of which are reflected in the recent MOT failure points. A physical inspection should prioritise the underbody to assess the extent of the recorded corrosion, specifically looking for structural scaling or surface rust on the subframe and suspension mounting points. The braking system requires close scrutiny; the history of parking brake failure and worn rear discs suggests a need to check for binding calipers or a lack of tension in the handbrake lever. During a test drive, the driver should feel for any unusual vibrations or judder under braking and ensure the parking brake holds the vehicle securely on a steep incline. The condition of the tyres is another immediate concern, as the latest advisory notes perishing and cracking on both rear tyres. These should be inspected for sidewall degradation that could compromise structural integrity. Additionally, the previous failures regarding the rear bumper and headlamps indicate a history of minor body damage and electrical faults, so a thorough check of all exterior lighting and the security of the rear bumper assembly is recommended to ensure no hidden structural damage exists behind the trim.
