2014 Infiniti Q50 2.1L Diesel · WH05 CCA

Recurring brake component degradation and structural corrosion represent the primary mechanical concerns for this vehicle. The most recent test on 09 September 2026 resulted in a failure due to insufficient windscreen washer fluid, followed by a pass with an advisory for worn, pitted, or scored brake discs. This follows a consistent pattern of brake-related advisories dating back to at least 2019, specifically regarding pitted or scored discs and thinning brake pads. Furthermore, the 2024 MOT record noted corrosion on the front sub-frame, indicating that structural oxidation is a documented characteristic of this vehicle's history. The vehicle has covered 107,132 miles over its 12-year lifespan, averaging approximately 8,928 miles per year. This usage pattern is typical for a vehicle of this age and suggests regular road use rather than prolonged periods of inactivity. From a mechanical standpoint, this level of annual accumulation is consistent with the observed wear on consumables such as brake discs, pads, and tyres. The steady mileage accumulation aligns with the progressive nature of the recorded advisories, particularly the recurring issues with the braking system components. A prospective buyer should pay close attention to the braking system and the reported sub-frame condition. Given the repeated advisories for pitted and scored brake discs across multiple years, a test drive should include several controlled applications of the brake pedal to check for any pulsation, judder, or unevenness in braking force. The 2023 failure regarding insufficient brake pedal travel is a significant historical point that warrants verification that the current hydraulic system and pedal feel are consistent and responsive. Additionally, the recorded front sub-frame corrosion should be visually inspected for any signs of progression beyond the previously noted state of not being seriously weakened. The history also includes various minor issues and advisories related to tyres and lighting, such as a malfunctioning tyre pressure monitoring system and an inoperative registration plate lamp. While these were addressed or noted as minor, the presence of tyre damage and nails in previous tests suggests that the tread and sidewall integrity should be closely examined. During a test drive, listen for any irregular road noise or vibrations that could indicate uneven tyre wear or issues with the suspension linkages, which may be influenced by the age and mileage of the vehicle.
