2012 Infiniti FX30D Auto 3.0L Diesel · RX62 BDU

Corrosion is the dominant theme in this FX30D’s MOT record, with fuel‑tank support straps, central exhaust heat shields and a rear body‑structure mounting repeatedly flagged as corroded across five tests. The most recent inspection on 21 October 2025 recorded a pass but retained the same trio of corrosion advisories, indicating that the underlying rust issues have persisted rather than been resolved. No outright failures have been logged, yet the consistency of these warnings suggests that rust mitigation will be a priority for any new owner. At 99,332 mi after fourteen years the vehicle averages just over 7,000 mi per annum, a mileage rate that sits squarely within normal private‑use expectations. The MOT history shows annual testing with no large gaps, implying the odometer reading is likely representative of actual use rather than a period of prolonged storage. This moderate annual accumulation means wear on consumables such as brakes and suspension components should be typical for a car of this age, but the mileage does not offset the need to address the recurring corrosion points. When inspecting the car, focus on the fuel‑tank support area: look for any signs of strap deterioration, rust flaking, or fuel leakage around the cross‑brace, and listen for metallic rattle when the engine is revved. Examine the central and front exhaust heat shields for cracked or perforated metal, loose mounting bolts and any audible rattling that could indicate loss of attachment. Inspect the rear chassis near the previously noted mounting point for surface rust that might be advancing toward structural steel, and feel for any looseness in the subframe when the vehicle is lifted. Any evidence of progressing corrosion should be treated as a repair item before committing to purchase. Tyre wear advisories appear on every test from 2023 onward, with all four road wheels reported close to the legal limit and showing edge wear. Verify tread depth on each tyre, ensuring it exceeds the 1.6 mm minimum, and check sidewalls for cracking, bulges or exposed cords that could precipitate a sudden failure. While the MOT did not flag brake or suspension faults, a thorough road‑test should include listening for knocks over bumps (which could reveal worn bushings or hidden rust‑related cracks), feeling for any steering pull or vibration, and confirming that braking feels firm and even. Addressing the corrosion and tyre wear now will markedly improve the vehicle’s roadworthiness outlook.
