What is the situation when the Equinox makes noise while releasing the accelerator during driving?

[ColinDella]

When the Equinox makes noise while releasing the accelerator during driving, it is due to a component failure in the accelerator release mechanism. Possible causes: First, the transmission; second, there may be an issue with the valve train; third, it could be engine carbon buildup. These conditions can all potentially cause a noise phenomenon when the accelerator is released during normal driving. Noise locations: Bearing noise: Generally, bearing noise is closely related to engine speed, becoming more pronounced at higher speeds. Differential or main drive gear noise: This type of noise typically becomes noticeable at speeds between 50 to 70 km/h. Due to different gear meshing surfaces, the noise is usually more obvious when accelerating and significantly reduces when releasing the accelerator. Oil pump or hydraulic system noise: This noise is closely related to engine speed but not to vehicle speed. At high speeds, the oil pump may experience suction obstruction, leading to noise.
