2006 Nissan Navara 2.5L Diesel · KG02 OAK

Structural integrity and chassis corrosion represent the primary mechanical risks for this vehicle, following a recurring pattern of significant failures regarding the rear suspension component mountings. The most recent test on 31 October 2025 resulted in a pass, but only after a failure three days prior for excessive corrosion on the nearside rear suspension mounting and an incorrect headlamp aim. This follows a history of serious and dangerous defects recorded in 2022 and 2024 concerning the offside rear vehicle structure and chassis. While the 2025 pass notes that a suspension component mounting repair has been covered in underseal, the repeated nature of these structural failures indicates a persistent issue with the chassis's resistance to corrosion in critical load-bearing areas. The vehicle has covered 124,700 miles over its approximately 20-year lifespan, which equates to an average annual accumulation of roughly 6,235 miles. This usage pattern is relatively low for a commercial vehicle of this age, suggesting it has not been subjected to high-intensity long-distance haulage. From a mechanical standpoint, this lower annual mileage means that while drivetrain components may have lower cumulative wear than a high-mileage equivalent, the vehicle has likely spent significant time stationary or in lower-speed environments, which can coincide with the observed progression of corrosion on the chassis and exhaust components. Prospective buyers should pay close attention to the underside of the vehicle, specifically focusing on the areas around the rear suspension mountings and the cross member. Given the history of major and dangerous corrosion failures, it is essential to inspect the quality of the underseal applied following the 2025 repair to ensure it is not merely masking deep-seated structural decay. During a test drive, listen for any knocking, clunking, or irregular movement from the rear suspension, as these could indicate that the structural repairs have not fully restored the stiffness of the chassis or that mounting points are still compromised. Additional attention should be directed toward the braking system and exhaust. The MOT history shows a pattern of worn front brake discs and a corroded offside rear brake pipe, which was previously obscured by grease. On a test drive, check for any pedal judder or uneven braking performance that might suggest disc issues, and listen for any changes in exhaust note that could indicate the minor central exhaust leak noted in 2024 has progressed. Furthermore, the recent failure regarding headlamp aim suggests that electrical or mounting stability in the lighting units should be verified to ensure consistent beam projection.
