2015 Infiniti Q50 2.1L Diesel · RV64 HBU

The vehicle passed its most recent MOT on 23 January 2026 at 81,978 miles, but the pass came only after a prior fail just one mile earlier on the same day, revealing persistent issues with rear suspension corrosion and front tyre condition. The maintenance trend is worsening, not improving, as structural and safety-critical defects have reappeared and escalated over the last two years, moving from minor play in anti-roll bar linkages to corroded struts and exposed tyre cords. Mileage accumulation is consistent with average annual use—roughly 7,500 miles per year—though there is a notable gap between the January 2024 and January 2025 tests, during which the car gained just under 11,500 miles, suggesting either heavy usage or a possible lapse in testing. The jump from 62,074 to 73,546 miles in a single year is unusually high for a 2015 model and may indicate extended periods of use without regular servicing. The final 8,400-mile increase from January 2025 to January 2026 is more typical, but the timing of the dual tests on 23 January raises questions about whether repairs were rushed or incomplete. A buyer must inspect the rear MacPherson struts for advanced corrosion, as they have been flagged in three consecutive tests and are now present at the point of pass with no repair recorded. The front sub-frame, which failed severely in January 2025, must be checked for residual rust or structural compromise, as this is a critical safety component. The tyres failed twice in rapid succession for tread wear and cord exposure, indicating either poor maintenance or aggressive driving; a full set should be replaced regardless of current tread depth. The parking brake efficiency failure in early 2025 also suggests neglected rear brake maintenance, and the binding calipers or seized cables should be tested under load. There is no evidence of recent fluid leaks or drivetrain issues, but the recurring suspension and corrosion problems point to a vehicle that has been inadequately maintained, particularly in terms of underbody protection and brake servicing.
