2004 Nissan Navar 2.5L Diesel · DX04 XAF

Structural integrity and progressive corrosion of the chassis and vehicle bodywork represent the primary mechanical risks for this Nissan Navara, following a significant failure on 14 October 2021. The MOT history reveals a worsening trend regarding oxidation, moving from general chassis and sill rust advisories in 2018 to major structural failures in 2021, where the offside rear vehicle structure was recorded as having significantly reduced rigidity due to corrosion. This follows a history of recurring issues with brake pipe corrosion and suspension component degradation that have been noted intermittently since at least 2016. The vehicle has covered 107,641 miles over its 22-year lifespan, which equates to an average annual accumulation of approximately 4,893 miles. This is a low annual mileage profile for a commercial vehicle of this age. While lower mileage can suggest less frequent mechanical wear on drivetrain components, the recorded history of corrosion and the long intervals between tests may indicate periods of stationary use or exposure to environmental elements without the benefit of regular road cleaning, which can accelerate the oxidation of brake lines and structural mounting points. Prospective buyers should conduct a rigorous inspection of the underside, specifically focusing on the sills, suspension mounting areas, and the rear structural assembly. Given the 2021 failure regarding reduced rigidity, it is essential to check for any signs of recent welding or structural repairs. On a test drive, pay close attention to the suspension for any knocking or clunking sounds over bumps, which could indicate the degradation of the ball joints and bushes flagged in previous years. Additionally, monitor the steering for any pulling or unevenness that might stem from the previously noted front suspension component corrosion and tyre wear patterns. The braking system requires careful scrutiny due to a history of excessively corroded and leaking brake pipes, as well as a major failure in 2020 for a binding offside rear service brake. During the test drive, listen for any grinding or squealing from the wheels and feel for any pedal judder or a spongy response, which could indicate compromised hydraulic integrity or sticking calipers. Furthermore, check for any visible seepage around the front power steering pump, a component that has been flagged for slight seepage in the past, which may require monitoring for fluid loss.
