2018 Mitsubishi Shogun 3.2L Diesel · YA18 FDO

The latest MOT test on the 2018 Mitsubishi Shogun, conducted on 2025-11-10, resulted in a clean pass with no recorded defects, marking a positive turnaround after a series of advisories and a major failure in the preceding year. While the vehicle’s maintenance history shows some recurring issues—particularly with front tyre wear, shock absorber condition, and brake performance—this latest test indicates a stabilization of these problems, suggesting either corrective action has been taken or the vehicle has settled into a more consistent operational state. The pattern of advisories from 2023 onwards, such as light misting in the front shock absorbers and tyre wear close to the legal limit, indicates wear that has been monitored rather than allowed to escalate, though the major brake fluctuation failure in 2023 highlights a critical area that required immediate attention. Overall, the trend is cautiously optimistic, with the vehicle now operating within legal and safety parameters, though vigilance remains necessary to prevent recurrence of these issues. The recorded mileage of 51,277 miles for an eight-year-old Shogun reflects a moderate annual usage rate of approximately 6,410 miles per year, which is within the expected range for this vehicle class. This usage level suggests a balance between regular driving and periods of inactivity, which can lead to specific wear patterns. Lower mileage might indicate prolonged standing, potentially causing issues such as brake disc corrosion or binding calipers due to moisture absorption, while higher mileage could accelerate wear on consumables like brake pads, suspension components, and fluids. The absence of significant mileage spikes or abrupt increases over recent years supports the stability observed in the MOT history, but it is prudent to consider how the vehicle’s maintenance schedule aligns with its operational profile. For instance, if the vehicle has been stationary for extended periods, internal corrosion or fluid degradation could be more pronounced than suggested by the mileage alone. For the prospective buyer, the most critical areas to inspect during a physical examination of the 2018 Mitsubishi Shogun are the front suspension and braking systems, given the recurring advisories and the major failure history. The light misting in the front shock absorbers suggests that the dampers may be nearing the end of their service life, with symptoms to watch for including excessive body roll during cornering, clunking noises from the suspension during bumps, or reduced ride comfort. A test drive should include slow-speed manoeuvres to check for uneven ride quality or excessive bounce, and listening for any hollow or metallic clunks that could indicate worn suspension bushes or broken coil springs. The brake fluctuation failure from 2023 is particularly concerning, as it may point to a binding caliper, warped discs, or a failing brake master cylinder. Signs to look for include a spongy or uneven pedal feel, pulsations through the brake pedal during braking, or a grinding noise from the front brakes when applying pressure. Immediate attention to these issues is recommended, as brake performance is critical to roadworthiness and safety. In addition to the suspension and braking systems, the tyre condition remains a significant concern given the repeated advisories about wear close to the legal limit. The front tyres, in particular, show signs of edge wear, which can indicate misalignment, uneven load distribution, or excessive camber angles. A thorough inspection should include checking the tyre sidewall for signs of perishing or cracking, which can weaken the tyre structure over time, especially in an eight-year-old vehicle. The tyre tread depth should be verified with a legal tread depth gauge, as wear close to the legal limit increases the risk of hydroplaning in wet conditions. The vehicle’s fluid levels—particularly the brake fluid, coolant, and transmission fluid—should be checked for degradation, as fluids can break down over time, even with moderate usage. A calendar-based service schedule for fluid top-ups and replacements is advisable, with the brake fluid being particularly susceptible to absorption of moisture, which can compromise braking performance. Finally, the battery health should be assessed, as prolonged inactivity or high mileage can lead to reduced cranking power, which may not be immediately apparent but could affect the vehicle’s starting reliability. A visual inspection for corrosion around terminals and a test of the battery’s charge capacity would be prudent.
