EV Shaking During Acceleration Due to Motor Mount Failure

To diagnose this cause, perform a physical inspection of the mounts securing the electric drive unit. Check for visible cracks, tears in the rubber bushings, or excessive movement of the motor/gearbox assembly when torque is applied. A technician should use a pry bar to check for play in the mount assemblies while the vehicle is on a lift to determine if the drive unit is shifting out of alignment during acceleration.
