2018 Infiniti Q30 2.1L Diesel · NJ18 LGG

The 2018 Infiniti Q30 presents a broadly stable mechanical picture, though the most recent MOT activity warrants close scrutiny. The vehicle passed its March 2026 test at 75,145 miles, but the preceding failure on 2 March 2026 at 74,733 miles reveals a pattern of deferred minor work. Both tests flagged the same two wear items: front brake discs worn but not excessively, and rear inner brake pads wearing thin. The tester also identified deteriorated anti-roll bar linkage ball joint dust covers on both front sides during the failed test. The subsequent pass suggests the dust covers were addressed, yet the recurring brake advisories point to components approaching replacement thresholds rather than being resolved outright. Maintenance appears reactive rather than proactive. The mileage accumulation is consistent with typical use for an eight-year-old vehicle, averaging roughly 9,393 miles per year. The jump from 66,193 miles in March 2025 to 74,733 miles by March 2026 represents approximately 8,540 miles in twelve months, a slight dip below the long-term average. No significant gaps appear in the record, with tests conducted annually between 2023 and 2026. The 2024 and 2023 tests were entirely clean, making the cluster of defects in early 2026 a notable departure from the prior two years of defect-free results. A buyer should prioritise a thorough inspection of the front suspension and braking components. The repeated advisories on front brake discs and rear inner pads indicate these parts are cycling through their service life faster than expected, possibly reflecting driving style or deferred replacement. Both front anti-roll bar linkage ball joint dust covers failed within the same test window, suggesting exposure to road debris or age-related deterioration across the front suspension. While the covers appear to have been replaced to secure the pass, the underlying ball joints themselves should be checked for play. The undertrays noted in 2025 may be masking corrosion or fluid leaks on the underside, so a lift inspection is advisable to examine subframe mounting points, exhaust fixings, and structural seams for early-stage rust. Tyre condition and alignment should also be verified, given the front-end suspension work flagged in the failure.
