2017 Infiniti Q50 2.1L Diesel · RK17 CBO

The vehicle remains roadworthy as of its most recent MOT on 2025-08-08, with a clean pass at 62,093 miles. The maintenance trend is stable in terms of passing standards, though it shows a consistent pattern of surface corrosion on the front subframe, with rear subframe corrosion noted in 2023. No major mechanical failures or safety-critical defects have appeared in the last five years, indicating the owner has maintained basic compliance, even if cosmetic structural issues persist. Mileage progression is steady and within expected parameters for a nine-year-old vehicle, averaging approximately 6,900 miles annually. Each MOT test occurred roughly annually, with no significant gaps or sudden spikes in mileage, suggesting regular use without long-term storage or excessive wear cycles. The 2025 test at 62,093 miles follows a 2,486-mile increase from the 2024 test, which itself rose by 1,894 miles from 2023 — a consistent, moderate growth that aligns with typical usage patterns for this class of car. The recurring surface corrosion on the front subframe, noted since 2021 and still present in 2025, warrants close inspection of the suspension mounting points and surrounding structural integrity. While not currently classified as a failure, this corrosion may indicate exposure to moisture or salt, and could progress to structural weakness if unchecked. The 2022 MOT also flagged long travel in the parking brake — a mechanical wear indicator — which should be examined for binding or reduced effectiveness. Brake components, particularly rear calipers and discs, should be assessed for wear or binding, as these are often affected by corrosion and moisture in the underbody. A buyer should prioritize a detailed mechanical inspection of the front and rear subframes, suspension bushes, and brake systems. Pay particular attention to any signs of rust penetration or structural fatigue around the subframe mounts, and test the parking brake for smooth release and full retraction. Tyre tread depth and wiper blade condition should also be verified, as these are common wear items that may have been neglected if corrosion issues were prioritized over routine maintenance. The vehicle’s history suggests it has been kept compliant, but not necessarily cared for with precision — a buyer should expect to budget for minor structural and mechanical upkeep.
