Volvo XC90 severe vibrations and noise during acceleration and deceleration at 15 mph on Volvo XC90

Some Volvo XC90 owners report experiencing severe vibrations and noise during acceleration and deceleration at around 15 mph, which may be linked to several potential issues. These vibrations could be caused by failing engine mounts, leading to noticeable disturbances when shifting gears. Additionally, excessive chassis vibration during acceleration might indicate underlying problems, particularly at highway speeds, which may not be as apparent at lower speeds. Some owners have found that replacing multiple motor or transmission mounts alleviates these acceleration vibrations. Furthermore, wheel damage or misalignment and imbalances in external components may contribute to engine vibration during acceleration. Gentle acceleration, especially on inclines or while going straight, may trigger these vibrations at low speeds. It is recommended that owners experiencing these issues have their engine mounts, chassis, wheels, and external components thoroughly inspected to determine the root cause.
