2018 Infiniti Q50 2.1L Diesel · RK18 FPZ

The 2018 Infiniti Q50 recorded here exhibits a stable but unusually low-mileage maintenance history, with the most recent MOT test conducted on January 6, 2023 , just under three and a half years ago at 25,614 miles . The vehicle passed both its 2022 and 2021 tests without any recorded defects, though the duplicate entry for January 2023 suggests a potential administrative anomaly rather than a mechanical issue. No advisories or failings were logged in any of the four MOT cycles, which implies either consistent upkeep or a vehicle that has not yet encountered significant wear. That said, the lack of any advisories —even for consumables like wiper blades or brake pads—is notable, as these are typically flagged in routine tests. The absence of emissions-related failings also suggests the catalytic converter and fuel system have remained within compliance. The mileage progression here is striking: 3,202 miles per year over the past eight years, which is well below the average for a vehicle of this age. Between January 2021 and January 2022, the odometer only advanced by 4,326 miles , indicating prolonged periods of inactivity. This could mean the car was stored, lightly used, or driven under controlled conditions. The 2023 test at 25,614 miles —just 5,100 miles above the 2022 reading—further reinforces this pattern. While low mileage generally correlates with reduced wear, the extended gaps between tests (particularly the 18-month interval between 2021 and 2022 ) raise questions about whether critical components like suspension bushes, coil springs, or brake calipers were serviced outside MOT requirements. The consistency of the mileage suggests the vehicle has not been subjected to heavy or irregular use, but this also means some wear items may never have been replaced proactively. Given the sparse MOT record, a buyer should prioritise an independent inspection of suspension integrity , particularly the rear suspension bushes and coil springs , as these are common failure points in vehicles of this age and mileage. The brake system , including caliper binding and disc thickness, should be checked—though no failings were logged, wear patterns could have developed over the extended intervals. Exhaust emissions should also be verified, as the lack of advisories does not guarantee the catalytic converter or oxygen sensors remain fully efficient. Structural corrosion , especially around wheel arches, sills, and the subframe, warrants close examination, given the vehicle’s age and the potential for hidden rust if it was previously stored in damp conditions. The tyre tread depth and condition should be scrutinised, as the absence of MOT failings does not confirm they have been rotated or replaced at optimal intervals. Finally, the engine bay should be inspected for leaks or degraded hoses, as these are often overlooked in low-mileage vehicles but can lead to costly failures if neglected.
