2016 Infiniti Q30 2.1L Diesel · MM16 XBS

The 2016 INFINITI Q30 currently holds a valid MOT pass certificate dated 10 April 2026 at 76,995 miles, yet the maintenance trend is clearly worsening. The preceding test on 9 April 2026 failed on multiple safety-critical items, including exposed ply on the nearside front tyre, three additional tyres worn to or beyond the legal limit, and rear brake imbalance with worn pads and scored discs. The fact that all four tyres required replacement within a single year suggests the previous owner deferred basic consumable upkeep until the MOT forced remedial work. While the rear brake components appear to have been rectified for the retest, the sudden clustering of failures points to a period of neglect rather than consistent preventative maintenance. The mileage progression is broadly typical for a ten-year-old car, averaging roughly 7,700 miles per year. Recorded mileages show a steady climb from 52,743 in March 2023 to 60,330 in April 2024, 67,836 in April 2025, and 76,995 in April 2026, indicating relatively consistent annual use. There are no alarming gaps or sudden jumps in the odometer record to suggest the vehicle has been standing idle or subjected to unusually high-mileage bursts. The record is clean and sequential, with no missing annual tests that would raise concerns about unmonitored periods of use. A buyer should focus their in-person inspection on the rear braking system and suspension geometry. The repeated appearance of rear brake disc scoring and pad wear, combined with rear brake imbalance flagged in the 2026 failure, warrants a thorough check of caliper slide pins, caliper pistons, and the handbrake mechanism for binding or uneven operation. The stepped inner edge wear pattern noted on both rear tyres in consecutive tests strongly suggests rear toe or camber misalignment, so a four-wheel alignment check is advisable before committing to a purchase. Suspension bushes, coil springs, and shock absorbers should be inspected for wear or deterioration, as misalignment of this nature often stems from worn rear suspension components rather than simply a tracking adjustment. The undertrays and engine covers noted as fitted in 2024 may still be in place, but a buyer should verify they are secure and not concealing corrosion or fluid leaks on the subframe and inner wing structures. Finally, a close visual inspection of the inner sidewalls of all four replacement tyres is prudent, given the severity of the defects recorded just weeks before the most recent pass.
