2015 Hyundai I30 1.6L Diesel · SX65 BYT

The 2015 Hyundai i30 presents a generally stable mechanical picture at its most recent MOT in August 2025 at 42,560 miles, though a pattern of recurring advisories points to gradual age-related wear rather than acute neglect. The tester flagged perished rear trailing arm bushes on both sides, perished front lower arm rear bushes beginning to separate, and front tyre wear close to the 1.6mm legal minimum. These are not dangerous failures, yet they confirm the car has not had recent suspension or tyre renewal. The rear subframe corrosion advisory has persisted since at least July 2024 and remains classified as not seriously weakened, which is reassuring for structural integrity but warrants ongoing monitoring. The mileage progression tells a story of very light use. Between July 2022 at 30,905 miles and July 2023 at 37,839 miles the car covered roughly 6,900 miles, then slowed markedly to just 1,681 miles in the following year and effectively zero between July 2024 and August 2025. That near-12-month standstill period is significant. Extended parking can accelerate rubber deterioration, cause flat-spotted tyres, and promote localised corrosion on brake discs and subframe surfaces, all of which align with the advisories now appearing. A buyer should focus the physical inspection on the areas the MOT record keeps returning to. Check the rear subframe closely for any progression beyond surface corrosion, particularly around mounting points and where undertrays trap moisture. Examine the rear trailing arm bushes and front lower arm rear bushes for splitting or movement, and expect that both sets may need replacement soon. Inspect the rear brake discs for scoring and lipping, and verify that the front tyres have adequate tread depth and even wear across the full width. Beyond the flagged items, pay attention to the windscreen washer system, which failed in the July 2024 test and may indicate a blocked jet, weak pump, or perished pipe. Look for signs of uneven tyre wear that could point to tracking issues masked by the worn bushes. The car's low annual mileage means consumable components have aged more than they have worn, so budgeting for suspension bushes, fresh tyres, and a thorough brake inspection would be prudent before long journeys.
