2013 Infiniti Q50 Sport D 2.1L Diesel · LL63 YMS

The most recent MOT test on the 2013 Infiniti Q50 Sport D occurred on 2025-10-30, where it passed with several advisories and one dangerous failure. This outcome follows a pattern of fluctuating results, with the vehicle failing in 2021 and 2024 before returning to a clean pass in 2025. The recurring issues—particularly the brake disc and anti-roll bar linkage defects—suggest a maintenance history that has not been fully addressed, indicating a need for proactive attention rather than a stable or improving trend. The presence of multiple advisories on tyre condition and minor structural wear further implies that while the vehicle is roadworthy, it has not been serviced with the same diligence as a lower-mileage model, which could lead to compounded wear if left unchecked. The vehicle’s recorded mileage of 136,257 miles over roughly 13 years equates to an annual usage rate of around 10,481 miles, which is consistent with typical usage for its age. However, the MOT history does not reflect a steady, high-mileage regimen; rather, the gaps between tests suggest periods of either low usage or prolonged idleness, which can exacerbate wear on components like brakes and suspension. Standing the vehicle for extended periods can accelerate corrosion on brake discs and calipers, leading to binding and reduced braking efficiency, while anti-roll bar linkages may develop excessive play or wear more rapidly when components are not regularly used. The combination of moderate mileage and irregular usage means consumables such as brake pads and suspension components are likely to have experienced accelerated degradation compared to a similarly aged vehicle with consistent driving. For the prospective buyer, the most critical areas to inspect during a test drive and physical examination are the braking system and suspension. The recent MOT failures highlight that the offside rear brake pads are dangerously thin, necessitating immediate replacement to prevent failure during braking. Listen for uneven brake pedal travel or a spongy feel, which could indicate warped discs or air in the hydraulic system. Inspect the rear brake discs for deep grooves, scoring, or cracks, as these signs of wear correlate with the DVSA’s findings. The anti-roll bar linkages, particularly the rear offside, show excessive wear in prior tests; check for excessive play in the linkage when the vehicle is in motion, and look for signs of oil leakage around the ball joints, which could signal impending failure. Additionally, verify that the near-side rear brake disc is not significantly weakened, as it was flagged in earlier tests, and ensure all brake calipers are functioning without binding. Beyond the mechanical checks, the tyres present a notable advisory from the MOT history, with near- and offside front and rear tyres showing signs of cracking or perishing. Given the vehicle’s age, sidewall cracking is a common issue that can compromise tyre integrity and safety, even if the tread remains above the legal minimum. Inspect the tyres for any signs of dry rot, blistering, or separation of the rubber from the carcass, and ensure they have been rotated regularly to prevent uneven wear. The front windscreens have been repeatedly damaged but remain non-adversely affecting visibility, so while this is not a mechanical concern, it is worth noting for future maintenance. Finally, consider a thorough check of the 12V battery and fluid levels, as prolonged idleness can lead to battery degradation or corrosion on terminals. For fluid servicing, check the engine oil, coolant, and brake fluid for any signs of degradation or contamination, particularly given the vehicle’s age and the wear already evident in the braking system. A service history review would also be beneficial to confirm that scheduled maintenance, such as timing belt replacement or suspension component servicing, has been undertaken.
