2011 Mitsubishi Shogun 3.2L Diesel · BU60 BNL

Chronic deterioration of the rear braking system and associated corrosion define the mechanical profile of this vehicle. While it achieved a pass on 18 August 2026, the record shows a recurring struggle with rear brake disc pitting and corrosion of the brake pipes, following a dangerous failure in 2025 due to critically worn rear pads. This trend suggests a systemic issue with the rear axle braking components and a general susceptibility to oxidation that has persisted across multiple testing cycles. With 104,939 recorded miles over fifteen years, the vehicle has averaged approximately 6,996 miles per year. This usage pattern is typical for a 4x4 of this vintage, suggesting it has not been subjected to extreme high-mileage wear but has spent enough time on the road to experience the gradual degradation of rubber seals and metal components. The moderate mileage means that while the drivetrain may have significant life remaining, the age-related corrosion seen in the suspension and braking lines is the primary mechanical concern. Immediate attention should be given to the rear braking system and the chassis. The recurring advisories for pitted rear discs and corroded brake pipes indicate that a full overhaul of the rear brakes may be necessary to ensure long-term reliability. During a test drive, feel for any unevenness in the brake pedal or a lack of firm response, and check for any pulling to one side under braking, which could relate to the previous binding issues noted on the nearside front caliper. Further inspection is required for the oil leaks flagged in previous years and the condition of the rear coil springs. While the steering rack gaiter was addressed following the 2025 failure, the steering should be checked for any unusual knocks or heaviness that might suggest further wear. Listen for metallic clunks or knocks over bumps from the rear of the vehicle, which would indicate that the corroded coil springs have deteriorated further. A physical inspection of the engine bay and underbody is essential to determine if the recorded oil leaks have been rectified or if they are continuing to weep.
