2015 Infiniti Q50 SE D Auto 2.1L Diesel · RK15 TZF

The most recent MOT test on 2025-03-08 confirms the vehicle remains roadworthy, with no defects or advisories recorded. This marks a stable pattern over the past three annual tests, including a duplicate entry for March 2024—one passed, one failed—though the absence of any recurring faults suggests either a genuine oversight in the system or consistent upkeep avoiding critical issues. The lack of advisories or repeated failures indicates no obvious trend of worsening mechanical concerns, though the clean record does not guarantee hidden wear. Buyers should note that the final pass in March 2025 is now just over five months old, nearing the annual MOT threshold, which could introduce uncertainty if the vehicle has since accumulated significant mileage without maintenance. The recorded mileage of 190,820 miles over approximately 11 years equates to an average of 17,347 miles annually, a rate higher than typical for a vehicle of this age. This suggests either frequent use or prolonged periods of operation without extended periods of rest, which could accelerate wear on components like suspension bushes, coil springs, and drivetrain fluids. The most recent MOT in March 2025 was conducted at 185,820 miles, meaning the vehicle has since covered an additional 5,000 miles without another inspection. While this is within the annual MOT window, the gap raises questions about whether intermediate servicing—such as brake pad replacement or fluid top-ups—has been addressed. The sparse history lacks pre-MOT servicing details, so buyers should verify if critical maintenance has been consistently performed. Given the clean MOT record, the primary focus for an in-person inspection should centre on high-mileage components that often fail without proactive servicing. The suspension, particularly the rear bushes and coil springs, warrants close examination for excessive play or corrosion, as does the brake system—including rear binding calipers or warped discs, which could develop without visible tread wear. The drivetrain, including the automatic transmission and differential, should be checked for leaks or unusual noise, especially given the high mileage. Corrosion at wheel arches, sills, and the subframe is also a concern for a vehicle of this age, particularly if it has been exposed to salted roads or poor storage conditions. Tyre condition, while not flagged in the MOT, should be cross-referenced with the recorded mileage to ensure no irregular wear patterns have gone unnoticed.
