2015 Infiniti Q50 2.1L Diesel · RX15 OJF

The 2015 Infiniti Q50 presents a mixed maintenance picture, with the most recent MOT pass on 21 February 2026 at 116,398 miles masking a very close call just three days earlier. On 18 February 2026 at 116,278 miles, the car failed with significantly worn front brake discs, front brake pads worn to the wear indicator, excessive parking brake lever travel, a defective offside registration plate lamp, and a nail in the nearside rear tyre. That all of these were rectified within 72 hours suggests a last-minute pre-test scramble rather than proactive servicing. The brake wear pattern is notable: both front discs and pads reached critical wear simultaneously, pointing to sustained neglect of braking components over the preceding months. The parking brake lever adjustment fault further reinforces that routine checks were being deferred. Mileage accumulation sits at roughly 10,582 miles per year over the vehicle's eleven-year life, which is typical for its age and does not raise immediate concern. The record shows a jump from 92,682 miles in February 2024 to 105,806 miles by February 2025, representing around 13,124 miles in that single year, slightly above the long-term average but not alarming. The gap between February 2025 and February 2026 saw approximately 10,179 miles added, returning to a more moderate pace. There are no suspicious mileage reversals or large unexplained gaps, and the annual test pattern has been consistent since 2024. Buyers should focus their in-person inspection on the front braking system and suspension. The recurring advisory for slight play in the nearside rear upper suspension arm ball joint, flagged in both February 2025 tests, indicates a component that has been monitored but not yet replaced. Whether this play has progressed beyond slight should be verified on a ramp, as a worn ball joint affects steering precision and tyre wear. The front brake discs and pads were clearly at the wear limit in February 2026, so a thorough check of disc thickness, pad depth, and caliper operation is essential to confirm the repairs were done to a proper standard rather than with budget components. The offside registration plate lamp fault appearing in both 2026 tests hints at a persistent wiring or bulb seating issue that may recur. Finally, inspect the underside for corrosion, particularly around suspension mounting points and brake lines, as the MOT record does not include any structural inspection notes but an eleven-year-old saloon of this mileage warrants careful scrutiny beneath.
