2007 Mitsubishi Shogun 2.5L Diesel · NJ07 PBY

The 2007 Mitsubishi Shogun carries a mechanical history dominated by recurring failures in suspension linkages and braking systems, punctuated by several clean MOTs interspersed with failures that suggest underlying design weaknesses rather than isolated incidents. The most recent test on 2025-03-31 returned a passing result but retained three active advisories: nearside and offside rear brake pads worn to critical thickness, excessively worn front and offside anti-roll bar pins and bushes classified as major defects, and a significant central exhaust leak allowing unburnt gases to escape. These findings sit atop a pattern where brake pad thinning persisted through at least two separate test cycles before being addressed, while the anti-roll bar failures—appearing in every year from 2021 onward—indicate a systemic weakness in that suspension component. Despite some clean records in 2024 and earlier years, the cumulative effect of these persistent issues creates a picture of a vehicle that remains roadworthy only under the watchful eye of a mechanic who knows how to interpret the ongoing nature of these defects. At 19 years old with 107,315 recorded miles, the Shogun accumulates approximately 5,648 miles per annum—a figure substantially lower than typical for its model year and raising questions about whether the odometer reading reflects genuine usage or periods of extended storage. Such a slow consumption rate does not necessarily preclude mechanical degradation, particularly in components exposed to stress regardless of distance travelled, meaning that even the modest mileage accumulation still subjects the engine, transmission, and drivetrain to regular load cycles. The absence of major failure events in early years contrasts with the concentration of issues beginning around 2020, when corrosion began affecting brake pipes and subsequent years saw repeated warnings on suspension bushings and brake wear. While the low annual mileage might reduce the urgency of some wear-related parts, the documented pattern of accelerating deterioration in the last five years suggests that the vehicle's remaining service life is best assessed against the persistence of these specific failure modes rather than against raw mileage alone. The anti-roll bar system represents the most consistent source of concern across the entire MOT history, with front and offside pins and bushes failing the 5.3.4(a)(i) standard on every single test record from 2021 through 2025. During a test drive you should pay close attention to any noticeable steering pull or body roll when navigating corners, as worn bushings allow excessive lateral movement that compromises handling and can place additional stress on the anti-roll bar itself. The rear anti-roll bar failures are equally telling—if the rear bar shows similar signs of fatigue, expect increased vibration through the chassis and potentially premature wear on the coil springs attached to the rear control arms. Additionally, the repeated advisory for central exhaust gas leakage indicates a compromised exhaust manifold or catalytic converter that may produce audible rumbling or a distinct smell of burnt fuel at idle, especially under load such as acceleration or highway cruising. Brake system health warrants particular scrutiny given the documented history of thin rear brake pads dating back to at least March 2023. On a test drive, listen for any grinding or squealing noise when applying the brakes, and feel for a soft or spongy pedal response—these symptoms align with the progressive thinning of the pads that triggered the 2025 failure. The oil leak advisories, now spanning multiple locations including the central front reservoir, rear front piping, and the front outer anti-roll bar linkage, point to a potential seal failure in the oil pan or a leaking line that could compromise engine lubrication and increase fire risk if the leak becomes severe. Given the exhaust gas leak classification as a major defect, inspect the central exhaust routing for visible cracks or loose connections, and confirm that the vehicle passes the smoke test fully before considering it safe for road use. A thorough visual inspection of all brake lines, coupling seals, and the underbody assembly will help determine whether these issues were resolved adequately or represent lingering problems that require professional repair before the car can be considered roadworthy.
