2004 Mitsubishi Shogun 3.2L Diesel · DA04 AOS

The vehicle presents a concerning roadworthiness profile characterized by a history of progressive structural degradation and deferred mechanical maintenance. While the most recent test in March 2022 at 158,946 miles passed with only slight corrosion, the vehicle has not undergone a recorded inspection for over four years. This significant gap in testing, combined with a history of major structural failures, makes the current mechanical state uncertain. The trend suggests a vehicle that has been maintained only to the point of failure rather than through proactive preventative care. The mileage pattern is consistent with a 22-year-old vehicle, averaging approximately 7,200 miles per year. There is a notable period of activity between April 2021 and March 2022 where the car covered nearly 20,000 miles, but the subsequent four-year lapse in MOT records is a major red flag. Such a long interval suggests the vehicle may have sat stationary for extended periods, which often accelerates the perishing of rubber components and seized brake calipers, or exacerbates internal corrosion noted in earlier records. A buyer must prioritize a thorough physical inspection of the chassis, specifically the sills and suspension mounting points. The record shows a critical failure in July 2020 at 132,676 miles due to excessive corrosion on the nearside rear suspension mounting and outer sills. Although this was later passed, structural rust on an age-related Shogun is often invasive and spreads. The history also highlights recurring issues with suspension bushes and steering rack gaiters, which were flagged as perished or missing in 2021 and 2016. The braking system requires close scrutiny given the documented history of imbalanced brakes and thin pads dating back to 2012. The 2016 report also noted heavy oil spray on the underside, which indicates potential engine leaks that could have degraded rubber hoses or masked the true extent of rustwork under the undertrays. Given the lack of recent data and the previous history of thinning structural metal, the risk of discovering significant mechanical fatigue or structural failure is high.
