2015 Infiniti Q70 2.1L Diesel · RO15 BZP

The most recent MOT test in November 2025 resulted in a pass, but the overall maintenance trend indicates a gradual decline in mechanical condition. While the vehicle consistently passes its tests, there is a recurring pattern of oil leaks from both the engine and the rear differential, as well as persistent issues with tyre wear and structural alignment. The presence of these advisories across multiple years suggests that minor defects are being monitored rather than proactively repaired, which may lead to more significant failures if left unaddressed. With a recorded mileage of 62,307 miles over an eleven year period, the vehicle has averaged approximately 5,664 miles per year. This is considerably lower than the national average for a luxury saloon of this age. While low mileage typically suggests less wear on the internal engine components and drivetrain, it often points to a history of short-distance urban use or extended periods of standing. Such usage patterns can be detrimental, often leading to the premature perishing of rubber seals, the accumulation of carbon deposits in the engine, and the degradation of brake system components due to inactivity. Prospective buyers should pay close attention to the recurring oil leaks noted at the front of the engine and the rear differential. During a test drive, be alert for any smell of burning oil or visible leaks on the driveway after the vehicle has been stationary. The consistent reports of inner-edge tyre wear on the front axle are a strong indicator of incorrect wheel alignment or worn suspension bushes. Listen for any clunks or knocks over uneven surfaces, particularly relating to the anti-roll bar linkages, and inspect the tyre treads for uneven wear patterns that would necessitate a full four-wheel alignment and potential suspension overhaul. Given the low annual mileage and the vehicle's age, a thorough physical inspection of all rubber components is essential. Check the tyre sidewalls for cracking or perishing, as previously noted in the history, and examine the brake discs for heavy corrosion or pitting, which can lead to brake shudder or binding calipers. It is critical to verify the service history for calendar-based fluid changes, as engine oil and coolant degrade over time regardless of the distance traveled. Finally, ensure the 12V battery is holding a healthy charge and that the parking brake operates with full efficiency, following a previous major failure in this area.
