2017 Nissan Navara 2.3L Diesel · PL17 RWN

The most recent MOT test on the 2017 Nissan Navara, conducted on 2025-10-06, resulted in a clean pass with no recorded defects, marking a positive turnaround from its previous failures. However, the vehicle’s MOT history reveals a pattern of critical issues, particularly with the suspension components, which were major failures in 2025-10-03. These fractures in both the offside front and rear coil springs indicate significant wear beyond the expected lifespan of these components, which typically degrade over time due to prolonged stress, poor alignment, or inadequate servicing. The fact that these failures occurred within a year of each other suggests either a pre-existing structural weakness or a lack of proactive maintenance to address early signs of coil spring deterioration, such as excessive play, uneven ride height, or audible clunking when driving over bumps. The advisory oil leak recorded in 2024-11-18 further underscores a recurring mechanical concern that should not be ignored, as persistent oil leaks can lead to increased engine wear, reduced lubrication efficiency, and ultimately catastrophic failure if left unaddressed. The vehicle’s mileage of 87,869 miles over roughly nine years represents an annual usage rate of around 9,763 miles, which is on the higher end for a vehicle of this age but not necessarily indicative of excessive wear if usage patterns were consistent. The absence of significant mileage gaps or rapid accumulation suggests the car has been driven regularly, which could accelerate wear on consumables like brake pads, tyres, and suspension components. However, the high mileage combined with the suspension failures highlights the importance of scrutinising the vehicle’s maintenance history for any missed servicing intervals, particularly for coil spring replacement and suspension bush inspections. Over time, coil springs can weaken from repeated flexing and stress, leading to premature failure, while oil leaks may stem from worn seals or gaskets in the engine or transmission, necessitating a thorough inspection of these areas. Given the history of coil spring fractures and oil leaks, the prospective buyer should prioritise a comprehensive mechanical inspection before purchase. During the test drive, listen for unusual clunking or rattling noises from the suspension, particularly when navigating bumps or corners, as these could indicate further coil spring or bush failure. Inspect the vehicle’s ride height and alignment for asymmetry, which may signal uneven wear or spring degradation. Additionally, check for any visible oil stains under the vehicle, particularly around the engine bay, transmission area, and undercarriage, as these could confirm the oil leak’s source and severity. If the oil leak is confirmed to be from the engine, ensure the engine oil is topped up to the correct level and consider a full oil change to flush out contaminants. For the coil springs, a visual inspection for signs of elongation, bulging, or cracks is essential, as these are clear indicators of impending failure. If the springs have already failed, the remaining springs may be compromised, and replacement would be advisable to prevent further accidents or suspension-related issues. For the 2017 Nissan Navara’s age and mileage, the buyer should also conduct a thorough physical inspection of other critical components that may not have been flagged in the MOT but are prone to wear or degradation over time. Check the tyre tread depth for sufficient grip, ensuring no areas are worn unevenly, which could indicate misalignment or suspension issues. Inspect the tyres for signs of sidewall cracking or perishing, as this is more common in older vehicles due to exposure to UV light and temperature fluctuations. Verify the condition of the brake system, including the discs, pads, and calipers, for signs of corrosion, binding, or uneven wear, which can occur if the vehicle has been left stationary for prolonged periods. The 12-volt battery should be tested for charge capacity and overall health, as older vehicles may struggle with electrical systems if the battery is weak or the alternator is failing. Finally, examine the exhaust system for corrosion, leaks, or structural integrity, as emissions-related advisories or failures could indicate catalytic converter or manifold issues, which are costly to repair. Additionally, check the service book for any missed scheduled maintenance, such as fluid changes, spark plug replacements, or timing belt servicing if applicable, to ensure the vehicle has been maintained according to manufacturer recommendations.
