2017 Nissan Navara 2.3L Diesel · PY17 AEJ

The most recent MOT tests on this Nissan Navara, conducted just four months ago on 11 March 2026, reveal a critical inconsistency: the vehicle failed the test despite no recorded defects being logged. This suggests either an administrative error in the MOT system or, more likely, a failure to address underlying issues that were not visibly apparent during the inspection. The lack of advisories or defects in the last two tests implies that while the vehicle may have passed the minimum legal requirements, there could be hidden concerns such as degraded suspension components, subtle brake wear, or exhaust system leaks that were not flagged. The trend over the past three years shows no mechanical failures being documented, but the repeated pass/fail anomaly at the same mileage (176,646) warrants further scrutiny. The recorded mileage of 176,646 miles over nine years equates to approximately 19,627 miles annually, which is unusually high for a vehicle of this age and class. This suggests either intensive commercial use or prolonged periods of operation without adequate maintenance. Notably, there is a significant gap between the 2024 and 2025 tests, where mileage jumped from 138,426 to 158,745—a 20,321-mile increase in just over a year. Such rapid accumulation raises concerns about whether routine services, such as brake fluid changes, suspension inspections, or differential maintenance, were conducted at appropriate intervals. The absence of any advisories or defects in the 2025 test despite this high mileage suggests either a well-maintained vehicle or a tester who overlooked critical components. Given the lack of documented faults but the repeated pass/fail anomaly in the most recent test, a buyer should prioritise an independent inspection of the suspension system, particularly the bushes, coil springs, and shock absorbers, as these are common failure points in high-mileage vehicles. The brakes should be thoroughly checked for uneven wear, binding calipers, or corrosion on the discs and pads, especially given the vehicle’s age and mileage. Structural integrity, including underbody corrosion around the sills, wheel arches, and exhaust system, should also be assessed, as these areas are prone to deterioration in vehicles with high annual mileage. Additionally, the exhaust emissions system—particularly the catalytic converter and oxygen sensors—should be verified, as these are frequently overlooked but critical for both performance and legal compliance.
