2018 Infiniti Q50 2.1L Diesel · MK18 JWM

This 2018 INFINITI Q50 passed its most recent MOT on 15 May 2026 at 57,853 miles, but the test reveals a pattern of component wear that has been building over the past four years. The most significant and recurring issue is wear in the suspension. The nearside rear anti-roll bar ball joint now shows slight play, a defect that appeared on the offside rear in both 2024 and 2025. This suggests progressive deterioration in the anti-roll bar linkage on both sides of the rear axle. Ball joints with play can lead to unpredictable handling, uneven tyre wear, and eventual failure if not addressed. The fact that this fault has migrated from one side to the other over successive test years indicates the suspension is aging under normal use. Tyre wear has also been a persistent advisory. The vehicle showed tyres worn close to the legal limit in four of the past five MOTs, with multiple instances of cuts and edge wear noted across different corners. Whilst none of these have been serious enough to fail the test, the pattern suggests the vehicle may not be running with correct wheel alignment or may be driven in a way that promotes rapid tyre degradation. The most recent test did not record new tyre advisories, which could mean fresh rubber has been fitted or wear has stabilised, but this remains an area to inspect closely.
