2015 Infiniti QX70 3.0L Diesel · RO15 BYV

The 2015 Infiniti QX70 is currently roadworthy following its most recent MOT on 2026-02-26 at 66,691 miles, passing with a single advisory concerning the offside rear tyre tread depth. However, the maintenance trend shows a concerning pattern of recurring tyre wear and engine-related issues, indicating inconsistent upkeep. The vehicle failed twice in 2024 and 2025 due to tyre tread depth problems, with the same issue appearing in three of the last four tests, suggesting a persistent lack of attention to tyre condition or potential alignment issues. The mileage progression shows a steady increase of approximately 6,000 miles per year, which is typical for a vehicle of this age. There is a notable gap between the 2024 and 2025 tests, with the vehicle accumulating nearly 5,000 miles in just over a year, possibly indicating periods of infrequent use or long-term storage. The 2024 MOT records show two entries on the same day—likely a retest—suggesting the vehicle may have been brought in multiple times to address the same issues, including the engine warning light and tyre concerns. Buyers should conduct a thorough inspection of the rear suspension components, particularly the rear coil springs and suspension bushes, as repeated tyre wear on the same axle may point to alignment or suspension wear. The recurring engine MIL (Malfunction Indicator Light) issues, even if not flagged as a failure in the most recent test, warrant a diagnostic check to rule out underlying engine or emissions faults. Additionally, inspect the brake calipers and discs for binding or uneven wear, as the rear tyres are often affected by brake performance. Structural rust, especially in the rear wheel arches and underbody, should also be checked, as these are common weak points on older SUVs.
