2017 Lexus NX 2.5L Hybrid electric (clean) · LJ67 UNP

Recurring deterioration of front suspension ball joint dust covers represents the most consistent mechanical trend for this vehicle, appearing in every test since March 2024. While the most recent test on 18 March 2026 resulted in a pass, the defects have progressed from a single offside minor to both nearside and offside front lower suspension arm ball joint dust covers being recorded as severely deteriorated. This pattern of recurring minor faults suggests that while the vehicle remains roadworthy, the rubber components protecting the suspension linkages are reaching the end of their functional life. The recorded mileage of 36,573 miles against a 2017 registration indicates a low annual usage rate of approximately 4,064 miles. This level of accumulation is significantly below the UK average for a vehicle of this age. While low mileage generally implies less wear on high-friction components, the MOT history shows evidence of tyre perishing and sidewall damage, which can occur when a vehicle is driven infrequently or spends extended periods stationary. The lack of mileage-related wear on mechanical components must be weighed against the potential for age-related degradation of rubber seals, bushes, and tyre sidewalls. Prospective buyers should pay close attention to the front suspension during a test drive to evaluate the impact of the deteriorating ball joint dust covers. Listen for any rhythmic knocking, clunking, or popping sounds when navigating uneven road surfaces or turning the steering wheel at low speeds, as these symptoms often indicate that grease is escaping the joints and causing internal wear. Additionally, the presence of a cut in the nearside front outer tyre sidewall noted in the 2025 advisory warrants a physical inspection to ensure no structural cord exposure has developed, which could lead to a sudden loss of pressure. The history of tyre cracking and perishing on the rear axle in 2023, combined with the low annual mileage, suggests that the rubber components may be hardening due to age rather than tread wear. During the inspection, check the sidewalls of all tyres for fine cracks or bulges. Any steering pull or vibration through the steering wheel at motorway speeds should also be investigated, as this could relate to either the previously flagged tyre issues or the condition of the front suspension geometry following the repeated deterioration of the ball joint covers.
