2017 Infiniti Q50 2.1L Diesel · RJ66 ODU

The vehicle passed its most recent MOT on 9 June 2026 at 49,129 miles with no recorded defects, indicating current roadworthiness. However, a prior test on 4 October 2025 revealed a recurring issue with the nearside rear anti-roll bar linkage ball joint having slight play (5.3.4 (a) (i)), which was flagged again in a failed test at 47,810 miles on the same date. This suggests the fault was unresolved until the most recent inspection, though it appears to have been addressed between October 2025 and June 2026. The engine’s malfunction indicator lamp (MIL) also triggered a failure in October 2025, but no subsequent advisories on this system were noted, implying the issue may have been rectified. The maintenance trend shows a temporary worsening in late 2025, followed by resolution, but the recurrence of the anti-roll bar issue warrants scrutiny. The recorded mileage of 49,129 miles over nine years equates to approximately 5,459 miles per year, a notably low figure for a vehicle of this age. This suggests either minimal usage or prolonged periods of inactivity, both of which can contribute to component degradation unrelated to wear from driving. The lack of significant mileage accumulation between the 2023 and 2026 tests—only 1,686 miles added since August 2023—indicates consistent, light use. However, this also raises concerns about potential corrosion or mechanical stiffness from extended idling, particularly in suspension bushes, coil springs, and brake components. The sparse advisory history, aside from the anti-roll bar and MIL issues, implies the vehicle has generally been well-maintained, though low mileage may mask latent problems. A buyer should prioritise inspecting the nearside rear anti-roll bar linkage for any residual play or premature wear, as this fault recurred in late 2025. The engine’s MIL status should be verified through diagnostic scans to confirm the 2025 issue was fully resolved. Suspension components, including bushes and ball joints, should be checked for stiffness or corrosion, given the vehicle’s low mileage and potential for standing-related deterioration. Brake discs and pads should be assessed for uneven wear, as binding calipers or warped discs could develop from infrequent use. Structural integrity, particularly around rust-prone areas like door sills and wheel arches, should also be inspected, as prolonged inactivity can accelerate corrosion. These checks will clarify whether the vehicle’s low mileage has preserved its condition or introduced hidden risks.
