2018 Infiniti Q50 2.1L Diesel · SJ18 XGF

The 2018 Infiniti Q50 presents a stable and improving maintenance trend, culminating in a fully clean MOT pass on 2 April 2026 at 75,723 miles with zero defects recorded. This is a significant turnaround from the February 2024 test cycle, where the car failed one day before passing on advisories. The 2024 failure flagged a missing offside rear wheel fixing and an excessively worn nearside front wheel bearing likely to break up, both serious mechanical risks that were evidently rectified before the subsequent pass. The same test also noted slight play in the offside rear anti-roll bar ball joint, a wear item that did not reappear in the 2025 or 2026 records, suggesting it was replaced or the play remained within tolerance. Two consecutive clean passes since then indicate the car is currently in sound mechanical order. The mileage accumulation is consistent and unremarkable for an eight-year-old saloon. The car covered roughly 5,200 miles between the February 2023 test at 51,734 miles and the February 2024 test at 63,474 miles, then approximately 7,000 miles per year through to the April 2026 test. This works out at around 9,500 miles annually, well within the typical range for a vehicle of this age. There are no suspicious gaps or sudden spikes in the odometer record that would suggest long periods of disuse or clocking concerns. The MOT history itself is regular, with tests conducted each spring, and the mileage progression between each entry is logical and steady. A buyer should still carry out a focused physical inspection despite the clean recent record. The 2024 failure for an excessively worn front wheel bearing and a missing rear wheel fixing raises questions about how the car was maintained prior to that point. Have the wheel bearings been replaced as a pair, or was only the failed side addressed? A test drive should include listening for humming or rumbling from the front end at speed, and the offside rear wheel should be checked for any signs of recent work or uneven torque marks. The inner edge tyre wear noted on both front tyres in February 2024 points to possible tracking or suspension geometry issues, so current tyre condition should be examined closely for any repeat of uneven wear patterns. The anti-roll bar ball joint play that appeared and then disappeared is worth a visual check underneath, along with all suspension bushes and coil springs, to confirm no fresh corrosion or deterioration has set in since the last test.
