2012 Mitsubishi Shogun 3.2L Diesel · R6 FET

The most recent MOT, dated 13 November 2025, resulted in a pass but was immediately followed by a failure for two major items: excessive play in the nearside track‑rod end ball joint and significant corrosion of the off‑side rear suspension mounting area. Over the last three years the record shows a pattern of recurring rear brake binding advisories and failures, culminating in the current structural and steering concerns. This trajectory indicates a maintenance trend that is deteriorating rather than stabilising, and the vehicle will likely require substantive remedial work before it can be considered reliably roadworthy. At 87,245 miles the 2012 Shogun averages just over 6,200 miles per annum, which is modest for a fourteen‑year‑old vehicle. The mileage suggests the car has not been subjected to high‑stress, high‑usage conditions, but the intermittent nature of MOT testing and the presence of standing‑time‑related defects imply periods of limited use interspersed with longer idle intervals. Low annual mileage can accelerate age‑related deterioration of rubber components, corrosion of suspension mounting points, and battery ageing, all of which are evident in the MOT comments. A prospective buyer should give the steering and rear suspension a thorough visual and tactile inspection. The nearside track‑rod end should be checked for play by moving the wheel at full lock and feeling for any looseness in the ball joint; audible clunks or a wandering steering feel under cornering would confirm the defect. The off‑side rear suspension mounting area must be examined for rust, cracked or thinned metal, and any distortion of the inner sill, as severe corrosion can compromise chassis rigidity. If any of these signs are present, replacement of the ball joint and reinforcement or replacement of the rear mounting brackets will be required, and the cost should be factored into the purchase price. In addition to the specific failures, the car’s age warrants a comprehensive condition check. Inspect all tyres for sidewall cracking, tread loss, or uneven wear that could indicate mis‑alignment from the suspension issues. Verify the health of the 12‑volt battery, especially its cranking voltage after a period of inactivity, and look for signs of electrolyte leakage. Examine brake discs and pads for surface rust, glazing, or uneven wear that may have resulted from the previously reported binding; a pulsating pedal or squeal under braking would be a warning sign. Finally, ensure that all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – have been refreshed within the recommended service intervals, as time‑based degradation can occur even on low‑mileage vehicles. Addressing these points will give a clear picture of the Shogun’s current roadworthiness and the scope of any imminent maintenance.
