2017 Infiniti Q50 2.1L Diesel · DC17 DEC

An uninterrupted run of seven passed MOT tests from 2020 through 2026, with only a single test in 2024 recording any defects, defines this Infiniti Q50 as a vehicle with a largely clean roadworthiness record. The most recent test on 8 June 2026 was passed with no advisories or failures recorded, continuing the stable upward trajectory that followed the only flagged inspection four years prior. There are no recorded failures, no structural corrosion advisories, no suspension or exhaust concerns, and no recurring component defects across the eight tests on file. The single advisory inspection in 2024 noted rear brake pads wearing thin and both front tyres worn on the inner edge, both items that have been resolved in the two subsequent clean passes, indicating that the underlying wear pattern has been addressed rather than allowed to persist. Overall, the official record shows a vehicle that has consistently met minimum roadworthiness standards without escalation of mechanical concerns. With eight MOT tests recorded over a six-year period and a current odometer reading of 39,678 miles, this Q50 has accumulated an average of roughly 4,400 miles per year, which is notably low for a nine-year-old vehicle. The mileage progression across tests shows steady but modest annual increases, with no gaps suggesting prolonged periods off the road and no sudden jumps that would indicate inconsistent use. Lower annual mileage of this nature typically results in reduced wear on major drivetrain components such as the engine, transmission, and clutch, but it can also mean extended standing periods which may promote corrosion in less-used mechanical areas such as brake discs, surface rust on underbody components, and potential dryness in suspension bushes and driveshaft boots. The relatively even testing history and consistent mileage increments suggest regular if light use, which on balance tends to be kinder to consumables and internal engine components than high annual mileage, though underbody and brake surface condition should still be physically examined given the light usage profile. For a prospective buyer, the specific advisories from the 2024 test deserve focused attention during inspection. The rear brake pad advisory means the friction material was approaching the limit two years ago, so the current pad thickness and the condition of the rear brake discs should be physically measured for lip wear and scoring, as worn pads left in service can accelerate disc wear. On a test drive, any grinding, squealing from the rear, or pulsation through the brake pedal under firm application would suggest the pads or discs have not been replaced since the advisory. The inner-edge wear on both front tyres points toward potential wheel alignment geometry issues, specifically negative camber or worn suspension components such as front wishbone bushes, track rod ends, or top mount bearings, which can cause uneven contact patch wear. On a test drive, listen for knocking or clonking from the front suspension over bumps and speed humps, pay attention to any steering pull to one side, and check for uneven or feathered wear across the full tread width on the current tyres, as persistent inner-edge wear on replacement rubber would confirm the geometry issue has not been rectified. Beyond the flagged items, a physical inspection should pay particular attention to areas the MOT cannot fully assess. Check for any oil seepage from the engine sump, valve cover gasket, and turbo or oil filter housing, as well as the condition of the undertray and any evidence of corrosion on subframe mounting points, brake lines, and suspension arms, especially given the vehicle's age. The electronic power steering and infotainment systems should be tested for warning lights or intermittent faults, as these are common age-related concerns on vehicles of this vintage. Finally, verify the service history independently and confirm the timing chain or belt replacement interval, as the Q50's V6 engine requires strict adherence to manufacturer schedules, and while the MOT record supports general roadworthiness, it cannot confirm internal maintenance has been carried out to schedule.
