INFINITI QX56 noise issue when accelerating from a stop, source undetermined on INFINITI QX56

Some Infiniti QX56 owners report experiencing various noise issues when accelerating from a stop, which may stem from common problems such as timing chain issues, exhaust manifold concerns, and front suspension problems. A specific "clicking" noise from the rear axle during acceleration has been noted, potentially indicating driveshaft-related issues. Additionally, some drivers report a whirring noise at slow speeds when decelerating, which, while not intrusive, differs from typical vehicle sounds. Other owners describe a pinging or castanet-like noise during acceleration, suggesting possible mechanical concerns. A clunking noise from the rear during acceleration or deceleration has also been reported as a symptom of a mechanical problem. To diagnose these noise issues, some drivers recommend replicating the sound through brake torquing and checking axle nut tightness. Furthermore, low power and excessive noise upon initial movement after the vehicle has been stationary overnight has been observed, possibly linked to the fan or transmission, but tends to resolve after shifting. It is advisable for owners experiencing these issues to seek inspection from a qualified mechanic to accurately identify and resolve the underlying cause.
