2016 Infiniti Q50 2.1L Diesel · GF55 GEF

The most recent MOT (30 June 2025) was a PASS , but it recorded a raft of advisory defects that together point to a vehicle whose suspension and corrosion issues are now the dominant concerns. The recurring pattern is clear: the rear sub‑frame shows corrosion (noted in both 2024 and 2025), and several suspension ball‑joints now have “slight play” – rear anti‑roll bar linkage and front lower arm. In addition, the off‑side front coil spring appears to have been fitted upside‑down and its boot or bump‑stop is missing, while the flexible brake hose on that same wheel is not fully clipped. Tyre health is also deteriorating, with the off‑side rear tyre described as “slightly damaged/cracking or perishing” and earlier MOTs flagging cracking on all four tyres. The hand‑brake travel is “slightly long”, and brake pads were flagged as thin in the 2024 failure. These defects have increased in number and severity since the clean 2022 MOT. The 2024 failure added an engine MIL fault and thin rear brake pads, suggesting that the vehicle’s overall condition is worsening , not stabilising. The trend is therefore one of progressive wear and corrosion rather than improvement. Mileage‑for‑age is about 10 300 mi yr⁻¹, which is typical for a ten‑year‑old car. The mileage itself does not indicate excessive use, but the age‑related corrosion and the breadth of suspension‑related defects imply that components are now reaching the end of their service life.
