2017 Infiniti Q30 1.5L Diesel · RK67 UFS

The 2017 Infiniti Q30 presents a stable and largely improving mechanical trend at its most recent MOT on 17 October 2025, where it passed cleanly at 114,723 miles with zero defects recorded. That clean sheet is significant. It follows a period of minor advisories in 2023 and 2024 that have since been resolved, suggesting the last keeper addressed wear items promptly rather than letting faults accumulate. The overall maintenance trajectory points to a vehicle that has been kept in reasonable order rather than neglected. The mileage profile tells a different story about usage intensity. Covering roughly 12,747 miles per year across nine years, this Q30 sits well above the typical UK average of around 8,000 to 10,000 miles annually. The jump from 73,403 miles in September 2021 to 114,723 miles by October 2025 represents 41,320 miles in just over four years, confirming sustained high-demand use. That kind of annual loading accelerates wear on consumable components, suspension bushes, brake assemblies, and drivetrain mounts, and it places greater importance on verifying service intervals for engine oil, transmission fluid, and coolant condition. The MOT record flags two recurring areas worth inspecting in person. Brake disc wear appeared as an advisory in the September 2023 test at 100,460 miles on both rear discs, and front brake fluctuation was noted in September 2021 at 73,403 miles. Both were cleared in subsequent tests, but the pattern indicates a vehicle that has worked its braking hard under sustained mileage. A buyer should physically inspect the condition of all four brake discs and pads, checking for lipping, scoring, and uneven pad deposition, and test the handbrake hold on a gradient given the rear disc history. The nearside rear tyre advisory in September 2024 at 108,398 miles for cracking or perishing also warrants attention. Sidewall degradation can stem from age, UV exposure, or underinflation, and the remaining tyres should be checked for date codes and tread depth consistency across the axle. Beyond the flagged items, the high annual mileage places extra scrutiny on suspension and structural integrity. A physical inspection should cover front and rear coil springs for sag or fracture, suspension bushes and drop links for play, and the subframe and mounting points for corrosion or cracking. Exhaust emissions were never flagged, which is encouraging, but a cold-start check for excessive smoke or unusual exhaust tone remains worthwhile given the engine's age and loading. The clean 2025 result is reassuring, yet the underlying usage pattern demands a thorough hands-on assessment before purchase.
