2016 Infiniti Q30 1.5L Diesel · TR15 FEB

The 2016 Infiniti Q30 has demonstrated a stable roadworthiness trend over the past three MOT cycles, with the most recent test on 13 November 2025 at 140,156 miles passing without defects. The vehicle’s history shows no serious recurring failures, though the November 2023 test revealed two minor but preventable issues: binding rear brakes and degraded anti-roll bar ball joint dust covers. These faults were rectified before the subsequent November 2023 retest, which passed cleanly, suggesting prompt attention to basic suspension and braking maintenance. The absence of major advisories or structural concerns in the last two tests indicates the vehicle has likely undergone routine servicing, though the binding brake condition hints at potential neglect of brake system adjustments or fluid changes. The recorded mileage of 140,156 miles over approximately nine years—roughly 14,000 miles annually—falls within the upper range for a vehicle of this age, which may accelerate wear on high-stress components like brakes, suspension, and drivetrain. The most notable mileage jump occurred between the November 2022 and November 2023 tests, where the odometer increased by 17,302 miles in just over a year, suggesting either intensive use or a period of active ownership. The gap between the November 2023 failure and the November 2024 test (10,107 miles) was similarly high, though the vehicle passed without issue, implying the repairs were effective. The most recent MOT, just six months ago, aligns with the standard annual testing cycle, though the lack of a 2026 test date means the vehicle has not yet been re-tested this year. A prospective buyer should prioritise an independent inspection of the rear brake system, particularly the calipers and hydraulic components, given the 2023 binding fault. The anti-roll bar ball joints, which failed their dust cover integrity in 2023, should be examined for wear, play, or corrosion—these are critical for suspension stability and should not be overlooked. The 2022 MOT noted worn rear brake discs, so the current condition of both discs and pads should be verified, along with the condition of the wheel cylinders or ABS components if fitted. Suspension bushes and coil springs, while not explicitly failed, warrant visual inspection for cracking or excessive compression, especially given the high mileage. Finally, the vehicle’s underbody should be checked for corrosion, particularly around the wheel arches and sills, as this is a common failure point in vehicles of this age and mileage.
