2018 Infiniti Q50 2.1L Diesel · NJ18 LDO

The 2018 INFINITI Q50 presents a mixed maintenance picture. The most recent MOT, conducted on 9 February 2026 at 74,326 miles, passed but flagged four advisories, indicating a decline in the previously clean record. The trend is worsening. Both nearside and offside rear anti-roll bar linkage ball joints were noted for slight play, a common wear item on this platform, and both front tyres were worn smooth on their inner edges, suggesting alignment or suspension geometry issues. A windscreen chip was also recorded as not affecting the driver's view. These items, while not fails, point to deferred attention that a buyer should not ignore. The mileage accumulation is broadly typical for an eight-year-old vehicle, averaging approximately 9,291 miles per year. The record shows a notable gap between the November 2021 test at 27,987 miles and the February 2023 test at 30,910 miles, covering just 2,923 miles across roughly fifteen months. This suggests a period of very light use or the vehicle standing idle. Mileage then climbed more rapidly, reaching 58,752 miles by February 2025, an increase of 27,842 miles in two years, before stabilising at 74,326 miles by February 2026. The record is sparse, with only five tests across five years, but the pattern indicates a shift from light to heavier recent use. The recurring theme across the history is tyre wear. All four tyres were flagged as worn close to the legal limit in February 2024 at 44,759 miles, and the February 2026 test again noted front tyre wear, this time specifically on inner edges. Inner edge wear on the fronts is a strong indicator of excessive negative camber or worn suspension bushes, likely linked to the anti-roll bar linkage ball joint play now present at the rear. A prospective buyer should have the suspension and four-wheel alignment inspected thoroughly, paying close attention to front lower control arm bushes, track rod ends, and the condition of the rear anti-roll bar links. The rear ball joint play, if left unaddressed, can accelerate tyre wear and compromise handling stability over time. The vehicle has no recorded MOT failures, which is reassuring, but the shift from two consecutive clean tests in 2021 and 2023 to multiple advisories in 2026 suggests routine inspection and preventative work may have lapsed. A pre-purchase inspection should include a thorough underbody check for corrosion, particularly around suspension mounting points and subframes, and a road test to confirm no knocking or vagueness from the rear end over uneven surfaces. The windscreen damage should be assessed against current MOT standards to determine whether replacement is imminent. Overall, the car appears mechanically sound but is showing early signs of wear that require prompt attention.
