2009 Nissan Pathfinder 2.5L Diesel · FE09 FEG

Severe structural corrosion is the primary mechanical concern for this vehicle, as evidenced by a failure on 12 March 2025 where the nearside rear vehicle structure was found to have significantly reduced rigidity over the axle and by the fuel tank. This indicates a deteriorating trend in the chassis integrity, following a pattern of failures and advisories involving critical wear items such as wheel bearings, CV boots, and suspension ball joints. The recorded mileage of 104,986 miles over approximately 17 years represents an average annual usage of 6,176 miles. While this accumulation rate is typical for the vehicle's age, the mechanical implications for a four-wheel-drive chassis of this era often involve a higher susceptibility to corrosion if exposed to road salt or damp environments, regardless of the total distance travelled. This usage profile suggests that wear on the drivetrain and suspension is consistent with age, but the structural failures outweigh the benefits of the moderate mileage. A physical inspection must prioritise the rear chassis and axle mounting areas to determine the extent of the corrosion and whether the repairs following the 2025 failure were comprehensive. During a test drive, listen for a rhythmic humming or droning noise from the rear, which would indicate recurring wheel bearing wear, and feel for any vagueness or stiffness in the steering wheel, which relates to the previously recorded wear in the steering column universal joint. Attention should be paid to the front suspension and drivetrain, specifically checking for knocks or clunks when traversing uneven surfaces, which would point to the worn ball joints and anti-roll bar bushes flagged across multiple tests. Inspect the nearside front inner CV boot for fresh grease spray and check the engine bay and underbody for evidence of the recurring oil leak noted in the records from 2022 and 2023. Finally, test the handbrake to ensure there is sufficient holding power, as previous records indicated limited reserve travel.
