2017 Infiniti Q50 2.1L Diesel · SJ67 VUD

The 2017 Infiniti Q50 presents a generally stable mechanical picture at its most recent MOT on 27 October 2025, when it passed at 46,312 miles with only a minor advisory for slight play in the nearside rear anti-roll bar linkage ball joint. That single advisory is not a serious structural concern, but it does indicate the onset of wear in a component that directly affects body roll and rear-end stability. The maintenance trend over the last four years is broadly stable rather than worsening, with no recurring failures on the same system and no dangerous defects recorded. Brake and tyre wear items have been flagged as advisories rather than failures, suggesting the previous owner addressed them before they became critical. The mileage pattern is notably low for a nine-year-old vehicle. Between the October 2022 test at 26,477 miles and the October 2024 test at 40,562 miles, the car covered roughly 14,000 miles in two years, a sharp increase after a period of very light use. The recorded mileage then plateaued completely, with no distance added between the October 2024 test and the October 2025 test, both recorded at 46,312 miles. This suggests the vehicle may have stood unused for an extended period before the most recent test. Prolonged standing can cause flat-spotted tyres, seized brake calipers, dried-out rubber bushes, and localised corrosion on brake discs, all of which a buyer should verify in person. The recurring advisories centre on rear brake pads and discs, with the October 2024 test flagging worn rear pads, scored rear discs, and a nearside rear tyre worn to the legal limit. Front brake pads were also noted as wearing thin in both 2023 and 2024, indicating the car has been driven hard enough to consume pads at a reasonable rate despite the low overall mileage. A buyer should inspect the rear brake calipers for signs of binding, check the condition of all four discs for lipping and scoring, and verify that the anti-roll bar linkage play noted in 2025 has not progressed. Suspension bushes, drop links, and exhaust mounting rubbers deserve close attention given the likelihood of deterioration from prolonged standing. A short test drive over uneven surfaces will quickly reveal whether the rear end knocks or wanders, confirming whether that ball joint advisory is cosmetic or symptomatic of deeper wear.
