2017 Infiniti Q50 2.1L Diesel · YA17 SEO

A pattern of deteriorating consumable condition has emerged in the last two years, contrasting with a previously clean record from 2021 through 2024. While the vehicle passed its latest test on 15 May 2026, this followed a failure on 11 May 2026 due to dangerous tyre tread depths on the rear axle and an insecure registration plate. The recent history shows a recurring trend of tyre wear and emerging brake component degradation that was not present in earlier inspections. The recorded mileage of 60,521 miles over approximately nine years represents an average annual accumulation of 6,725 miles. This usage profile is typical for the age of the vehicle and suggests a consistent pattern of use rather than prolonged periods of inactivity. Mechanically, this level of mileage typically coincides with the expected wear cycle for braking systems and tyre compounds, which aligns with the defects noted in the most recent testing cycle. Immediate attention is required for the tyre condition across all four corners. The most recent advisories highlight that the front tyres are perished, cut, and in one instance contain a nail, with wear concentrated on the inside edges. During a physical inspection, check the tyre sidewalls for cracking and the tread for uneven wear patterns, which may indicate a requirement for wheel alignment. The braking system shows signs of significant wear, specifically regarding worn front discs and pitted or scored rear inner discs. There is also a contradictory history regarding the parking brake, with high travel noted in 2025 and little reserve travel recorded in 2026. On a test drive, feel for any pedal judder or steering wheel vibration during braking and ensure the parking brake holds the vehicle securely on an incline.
