2009 Infiniti FX 3.7L Petrol · JGZ 5762

The vehicle passed its most recent MOT in September 2025 at 122,364 miles, but the test revealed multiple advisories that suggest a worsening maintenance trend. While technically roadworthy, recurring issues with brake pipes, power steering seepage, and sub-frame corrosion indicate deferred upkeep. The prior failure in August 2025 flagged worn suspension joints and electrical faults, many of which were only partially addressed — not repaired — to achieve the subsequent pass. This pattern implies reactive rather than preventative maintenance. With 122,364 miles on a 2009 model, annual usage averages around 7,200 miles, which is unremarkable for its age. However, between January 2023 (105,064 miles) and August 2024 (111,351 miles), the car accumulated just over 6,000 miles in 20 months — suggesting light or intermittent use. Then, between August 2024 and September 2025, mileage jumped by 11,000 miles in just 13 months, coinciding with the emergence of more serious mechanical advisories. That spike in usage likely accelerated wear on suspension and braking components already showing early signs of neglect. A buyer must physically inspect the rear sub-frame for active rust progression — while not yet structurally critical, corrosion in mounting areas on both sides suggests environmental exposure and potential future failure points. The front brake pipes, noted as corroded and grease-covered in the latest test, should be cleaned and examined for surface pitting or thinning; replacement may be imminent. The power steering rack boot seepage and previously worn offside ball joint point to suspension integrity concerns — check for play in steering response and clunking over bumps. Electrical gremlins, including plate lamps and position lights, hint at neglected bulb circuits or poor grounding — simple fixes, but symptomatic of broader inattention. Given the age and the nature of advisories clustering around structural, hydraulic, and electrical systems, a pre-purchase inspection should focus on underbody integrity, brake line condition, and suspension bushings. The catalytic converter heat shield remains insecure per 2024 notes — verify it hasn’t since detached or caused exhaust damage. Tyre pressure monitoring system warnings have appeared twice without resolution; ensure sensors are functional or budget for recalibration. This is not a failing vehicle, but one requiring immediate investment to arrest compounding deterioration.
