2014 Infiniti QX70 3.0L Diesel · X12 MBA

The defining mechanical thread across the MOT history of this 2014 Infiniti QX70 is a steady accumulation of advisories centred on the braking system and tyres, culminating in the most recent test on 20 April 2026 where the car passed with only minor window tint defects noted. From the 2022 test onwards, the front brake discs have been flagged repeatedly for wear, pitting, and lipping, which suggests progressive deterioration of the rotor surfaces rather than a single isolated event. Tyre perishing advisories have also surfaced on both front and rear axles in 2022 and again in 2025, indicating that the rubber compounds on this vehicle are likely ageing in line with the car's twelve-year span regardless of mileage. The combination of a clean pass history with no recorded failures alongside these recurring component advisories points to a vehicle that has remained roadworthy throughout testing but shows the natural wear patterns of a car of its age. Against an average annual accumulation of roughly 7,138 miles, the usage profile of this QX70 sits broadly within typical parameters for a twelve-year-old vehicle, with no extended gaps in the MOT testing sequence to suggest prolonged periods off the road. The relatively modest mileage means that the mechanical wear observed on the brake discs and tyres is more attributable to age-related deterioration, environmental exposure, and occasional use rather than heavy everyday driving. With this kind of usage, components such as brake calipers, flexible brake hoses, suspension bushes, and coolant hoses may have aged internally even where the external surfaces appear intact, and standing periods between uses can accelerate corrosion on underbody components and seizure of brake mechanisms. Buyers should therefore interpret the mileage as neither unusually low nor high, but be mindful that age-related rubber and metal fatigue remains a factor regardless. When inspecting this vehicle in person, the brake system should be the primary area of focus given the three consecutive advisories on the front discs. On a test drive, listen for any grinding, squealing, or pulsation through the brake pedal under firm application, as deep disc pitting can produce vibration and reduced bite. Inspect the disc edges visually for a pronounced raised lip and check the disc faces for heat, scoring, or blueing that might indicate warping. Confirm the front brake pad material thickness through the wheel spokes and look for uneven wear patterns that could point to a seized caliper slider, which is common on vehicles that see infrequent use. Any roughness or judder when braking from higher speeds would warrant immediate disc replacement before purchase. The tyre perishing advisories recorded in both 2022 and 2025 warrant close attention to the current set of tyres fitted, as the same advisory appearing across tests suggests the rubber may have been in service for an extended period. Check the sidewalls carefully for hairline cracks, crazing, and any bulging, particularly in the lower sidewall area where flexing occurs. Beyond the flagged items, examine the underbody thoroughly for corrosion on subframe mounting points, suspension arms, and brake pipe runs, as salt exposure over twelve UK winters can compromise structural integrity even where no advisory has yet been raised. During the test drive, pay attention to any clonks or knocking from the front suspension over uneven surfaces, wandering steering at speed, or uneven tyre wear that might indicate worn bushes or tracking issues, all of which would be consistent with the age and advisory profile of this particular QX70.
