2013 Mazda 6 2.2L Diesel · SY62 TZH

Significant structural corrosion and critical braking failures define the recent mechanical history of this vehicle, culminating in a failed test on 6 November 2024. The most recent inspection identified a major defect involving the offside rear outer integral body structure, where the outer sill was noted as detached and corroded within the suspension component area, compromising structural rigidity. This failure was accompanied by a dangerous defect regarding insufficient offside rear brake pad thickness and an inoperative parking brake on one side. This represents a worsening trend in mechanical integrity compared to the 2023 pass, moving from minor suspension and brake advisories in 2022 to serious structural and safety-critical component failures in the latest record. The vehicle has covered 199,135 miles over its thirteen-year lifespan, averaging approximately 15,318 miles per year. This high annual mileage suggests consistent, heavy usage which typically accelerates the wear of consumable components and suspension elements. Such a usage pattern correlates with the recorded history of frequent component replacements and wear-related failures, particularly concerning the braking system and steering linkages. The high mileage increases the likelihood of fatigue in rubber bushes and hydraulic lines, which is consistent with the documented history of corrosion on brake pipes and worn suspension bushings. Prospective buyers should pay close attention to the integrity of the chassis and sills, given the recorded structural failure of the offside rear outer integral body structure. During a test drive, any unevenness in how the vehicle handles bumps or any audible creaking or knocking from the rear suspension area could indicate further degradation of the mounting points or the sill. The history of brake pipe corrosion, specifically noted in 2020, and the recent failure of brake pads and the parking brake, necessitates a thorough inspection of the entire braking system. Listen for any grinding noises during deceleration or a pulling sensation to one side, and feel for any sponginess or unevenness in the brake pedal pressure. Suspension and steering components have been a recurring theme in the MOT history, with previous dangerous failures involving track rod ends and anti-roll bar linkages. While these were addressed in earlier tests, the 2022 advisory for a worn offside front suspension arm bush and the 2024 structural issues suggest that the suspension geometry and mounting stability require careful verification. On the road, check for any steering wander, vibration through the steering wheel at speed, or a pulling sensation that suggests the track rod ends or bushes are no longer maintaining correct alignment. Additionally, the advisory for a minor exhaust leak in the latest test should be investigated to ensure the exhaust system is not further degrading due to corrosion.
