2004 Mitsubishi Shogun 3.2L Diesel · WM04 CEK

The most recent MOT test on the 2004 Mitsubishi Shogun was conducted on 2025-03-21 and resulted in a pass with no recorded defects, marking a positive continuation of the vehicle’s roadworthiness. Despite the absence of failures in the last three years, the advisory history from previous MOTs reveals a pattern of recurring issues that require careful consideration. The advisories from 2022—particularly the nearside and offside rear brake pipe corrosion and grease contamination—suggest persistent wear or improper maintenance in the braking system, which could indicate underlying issues such as leaking seals, contaminated brake fluid, or even potential hydraulic failure. Additionally, the thin brake pads noted in 2018 and 2019 highlight ongoing friction system degradation, with pad thickness below the legal minimum, necessitating imminent replacement to prevent overheating, warping, or reduced braking effectiveness. The absence of failures in recent tests may be misleading if these advisories are not addressed, as they could escalate into more severe mechanical or safety-related problems if ignored. The recorded mileage of 99,061 miles for a vehicle aged approximately 22 years represents a remarkably low annual usage rate of around 4,503 miles per year, which is far below the typical expectations for a vehicle of this age and size. Such low mileage often correlates with periods of prolonged inactivity, particularly if the vehicle was stored without regular movement, which can exacerbate issues like corrosion, fluid degradation, and component stiffness. However, the absence of significant mileage accumulation over the past few years does not necessarily mean the vehicle is well-maintained; instead, it may suggest a lack of routine servicing or exposure to harsh environmental conditions that accelerate wear. The low mileage profile also raises concerns about potential standing-related corrosion, particularly in the brake system, exhaust components, and undercarriage, where moisture and contaminants can accelerate rust formation. For a prospective buyer, the most critical areas to inspect during a physical examination and test drive are the braking system, exhaust components, and general structural integrity. The rear brake pipes showing corrosion and contamination are particularly concerning, as they may indicate brake fluid leakage, which can lead to hydraulic failure or contamination of the system. On a test drive, listen for uneven braking performance, a spongy or soft pedal feel, or any signs of pulsation or vibration, which could signal warped discs, contaminated fluid, or binding calipers. Inspect the rear brake pads and discs for excessive wear, scoring, or glazing, and check for any fluid leaks around the brake master cylinder and caliper seals. Additionally, verify the condition of the rear brake pipes for cracks or severe corrosion, and ensure there is no grease or debris buildup that could impede brake function or indicate a failing seal. Beyond the braking system, the vehicle’s age and low mileage warrant thorough checks on fluid degradation, tyre condition, and electrical systems. Given the vehicle’s age, inspect the tyres for signs of sidewall cracking, perishing, or uneven wear patterns, which could indicate improper alignment, suspension issues, or prolonged standing. Check the tyre tread depth for legal compliance and listen for any unusual noises during a test drive, such as clunking or thumping, which may suggest worn suspension components like coil springs, shock absorbers, or suspension bushes. Verify the condition of the 12-volt battery and associated electrical connections, as low usage can lead to battery failure or poor starting performance. Finally, ensure all fluids—brake fluid, coolant, oil, and transmission fluid—are at the correct levels and free from contamination, as standing fluids can degrade over time, leading to premature component failure or reduced roadworthiness. If possible, review the service history to confirm that time-based maintenance, such as oil changes and fluid top-ups, has been conducted according to the manufacturer’s recommendations.
