2018 Infiniti Q50 2.1L Diesel · A8 AYD

Verdict for a 2018 INFINITI Q50 (40,771 mi) The most recent MOT (28 April 2026) was passed, but it recorded wear on both rear brake discs – the nearside and offside discs are described as “worn, pitted or scored, but not seriously weakened” (1.1.14 (a)(ii)). No other safety‑critical defects were noted. A year earlier (May 2024) the MOT flagged the rear tyres as “worn close to the legal limit, worn on edge and cracked” (5.2.3 (e)). No tyre comment appears on the 2025 or 2026 tests, which suggests the tyres were likely replaced after the 2024 warning. The only other recorded defect was a practical observation in 2022 (rear child seat obstructing belt inspection), which does not affect the vehicle’s mechanical condition. Pattern and trend The recurring issue is rear‑wheel wear – first the tyres in 2024, now the brake discs in 2026. This points to a consistent load on the rear axle, which is typical for a rear‑wheel‑bias or for a vehicle that is driven mainly in city traffic where brake use is frequent. The brake disc wear is noted but not yet at a failure level, indicating the problem is developing but not yet critical. Overall the MOT record is otherwise clean, so the trend appears stable: the vehicle has not accumulated new safety defects beyond the expected wear items. Mileage versus age At roughly 5,100 mi per year, the Q50 has been driven well below the average for an eight‑year‑old car.
