2014 Infiniti QX70 3.0L Diesel · FKZ 6070

The vehicle most recently passed its MOT on 10 December 2025, but the overall maintenance trend is concerningly stagnant. A review of the history from 2021 onwards reveals a pattern of recurring advisories that have not been rectified. Specifically, corrosion on the brake pipes and seepage from the power steering system have appeared in almost every test for the last five years. This indicates a reactive approach to maintenance where the vehicle is kept just within legal limits rather than being proactively serviced to prevent mechanical degradation. With a recorded mileage of 55,658 miles over twelve years, the vehicle has averaged approximately 4,638 miles per annum. This is significantly lower than the national average for a vehicle of this age and class. While low mileage is often viewed as a benefit, in this instance, it suggests the car has undergone periods of prolonged standing. Such usage patterns often lead to accelerated deterioration of rubber components and increased susceptibility to surface corrosion, which is directly reflected in the persistent MOT advisories. A prospective buyer must pay close attention to the braking system and steering gear. The recurring advisories regarding corroded brake pipes, particularly on the nearside front and rear, suggest that the metal is pitting; you should inspect these lines for any signs of flaking or deep rust that could lead to a hydraulic failure. During the test drive, listen for any unusual whining or heaviness in the steering, which would indicate that the power steering seepage has progressed to a more serious leak. Furthermore, the repeated mentions of tyre perishing and edge wear suggest the tyres are aged and may have developed sidewall cracks, compromising grip and safety. Given the low annual mileage, several age-related checks are essential regardless of the odometer reading. Inspect the brake discs for heavy surface corrosion or evidence of binding calipers, which often occurs when a vehicle sits idle. Verify the health of the 12V battery, as infrequent use often fails to maintain a full charge. You should also scrutinise the service history to ensure that engine oil and other critical fluids have been changed based on calendar intervals rather than mileage, as oil degrades over time regardless of use. Finally, check for any perished suspension bushes or cracked coil springs, as rubber components harden and fail over a decade of service.
