2017 Infiniti Q30 Premium Tech D 1.5L Heavy oil · RO17 WVT

The most recent MOT, performed on 9 June 2026, was passed with no recorded defects, indicating that the vehicle met the statutory safety and emissions standards at that date. Over the preceding three years the record shows a generally stable pattern of compliance, with passes in 2024 and an advisory only in 2023, but a major failure was logged in June 2025 for a fractured off‑side rear coil spring. The presence of that failure suggests that a significant suspension component required replacement, and the subsequent pass in 2025 implies the repair was carried out and accepted by the examiner. Overall the trend is therefore stable, provided the coil‑spring repair was properly executed and no further hidden damage remains. At 59 360 mi the 2017 Infiniti Q30 Premium Tech D averages roughly 6 600 mi per year, which sits comfortably within the typical UK usage envelope for a vehicle of its age. There are no obvious mileage spikes or long periods of inactivity evident from the MOT chronology, so the wear on engine, transmission and drivetrain components is likely to be consistent with normal calendar ageing rather than excessive mileage abuse. The modest annual mileage reduces the likelihood of premature wear on wear items such as clutch plates or timing chain, but it also raises the possibility that the car may have spent extended periods stationary, a factor that can affect battery health and corrosion of brake components. Prospective buyers should obtain the full repair invoice for the off‑side rear coil‑spring replacement and confirm that the associated rear damper, mounting brackets and lower wishbone were inspected and re‑torqued as required. On a test drive listen for any deep thumps or clunks when the rear wheels are loaded over bumps, and check that the rear tyre wear pattern remains even, which would indicate that the new spring is correctly seated and the suspension geometry is intact. The 2023 advisory about undertrays obscuring components warrants a visual inspection of the under‑body shielding to ensure there is no trapped moisture or corrosion on the exhaust, brake lines or fuel system, and that the undertrays are securely fastened and not interfering with heat dissipation. Given the vehicle’s age, a thorough visual and tactile check of the tyre sidewalls for cracking or dry‑rot is essential, as rubber can perishes even on low‑mileage cars. Verify the 12 V battery’s cranking voltage and examine the terminals for any signs of sulphation, especially if the car has been stored for long periods. Inspect the brake discs for surface rust, scoring or uneven thickness, and confirm that the calipers move freely without sticking, as calendar‑based corrosion can cause brake drag. Finally, confirm that all fluid service intervals—engine oil, coolant, brake fluid and DSG transmission fluid—have been observed in accordance with the manufacturer’s schedule, and request a recent service booklet or receipt to substantiate the timing of those changes.
