2018 Infiniti Q50 2.1L Diesel · RK18 FRF

The most recent MOT test on July 9, 2025, reveals a vehicle that narrowly passed despite severe tyre wear and critical brake component failures just one day prior. The July 2025 failure—with all four tyres at or beyond the legal limit and rear brake pads and discs flagged—demonstrates a pattern of neglect rather than mechanical instability. The subsequent pass in July 2025, only 24 hours later, suggests the tyres were replaced or repaired, yet the underlying issue of excessive tread wear persists, as evidenced by the same faults recurring in 2022. This indicates a recurring problem with either tyre rotation, alignment, or driver habits rather than a failing suspension or structural defect. The mileage progression shows a steady accumulation of approximately 7,800 miles annually, which is typical for a vehicle of this age. However, the gap between the 2024 and 2025 tests—covering 18,983 miles in just over a year—is unusually high for a car with no recorded defects in 2024. This rapid mileage suggests either heavy usage or prolonged periods without intermediate maintenance, which could accelerate wear on non-MOT-tested components like suspension bushes, coil springs, and drivetrain fluids. The 2022 to 2023 interval, spanning 5,428 miles, contrasts sharply with the later period, implying inconsistent servicing or ownership changes. A buyer should prioritise an immediate inspection of the suspension system, particularly the rear, where binding calipers or worn mounting bushes could explain the recurring brake-related advisories. The repeated tyre wear faults—especially the balding inner edges—point to either incorrect tyre pressures, aggressive cornering, or a misaligned front end. Structural corrosion should be checked at wheel arches, sills, and subframe areas, as prolonged standing or poor storage could accelerate rust. Finally, the brake system warrants thorough examination: the rear discs were noted as pitted or scored in 2025, which may indicate thermal damage or inadequate cooling, while the pads’ rapid wear suggests either heavy braking or low-quality replacements. Fluid levels and condition in the brake and power steering systems should also be verified, as these are not MOT-tested but critical to long-term reliability.
