2012 Infiniti FX 3.0L Diesel · RX62 BHY

A recurring oil leak and emerging component wear define the mechanical profile of this vehicle, despite a consistent pass rate across its recorded history. While the latest test on 7 October 2026 resulted in a pass, it reintroduced concerns regarding oil leakage in the gearbox area and identified new issues with front brake disc corrosion and a loose exhaust component. This follows a period of clean tests between 2024 and 2025, suggesting that certain wear-and-tear items are now manifesting more prominently. The recorded mileage of 99,828 miles over a fourteen year period reflects a typical annual usage rate of approximately 7,131 miles. This level of accumulation suggests a balanced usage profile, meaning the drivetrain and chassis have been subject to standard operational stresses without the extreme wear associated with high-mileage vehicles or the degradation often found in cars that have spent extended periods stationary. Attention must be paid to the gearbox area due to the oil leak noted in both 2023 and 2026. During a test drive, the buyer should monitor for any hesitation, erratic shifting, or unusual noises from the transmission. The reported corrosion on the nearside and offside rear lower suspension arms from 2023, combined with the current front disc corrosion, indicates a susceptibility to surface oxidation. It is advisable to inspect the rear suspension linkages for any signs of advanced pitting or structural degradation. The loose exhaust component mentioned in the latest inspection warrants a physical check to ensure it is not vibrating against the chassis or causing an audible drone. Additionally, the presence of corrosion on the front brake discs should be evaluated during braking for any pedal judder or steering wheel vibration, which can occur when discs are unevenly worn or pitted. A thorough visual inspection of the underbody is necessary to confirm that the suspension corrosion has not progressed beyond the advisory stage.
