The most common problem with the engine mount is when the rubber part breaks or separates or when liquid starts leaking out of the liquid-filled mount.
Common symptoms of a failed engine mount is the increase in engine noise and vibration felt inside the car.
Often, the excessive vibration is more noticeable at idle with the transmission engaged. For example, in some 07-08 Honda Civic mo
dels, a failing passenger side mount can cause a vibration and growling noise
felt in Reverse when the engine is started cold.
In Mazda 3, a broken top engine mount can cause vibration at idle, especially noticeable when the transmission is in Drive.
In some cars, a broken engine mount can also cause a noticeable jolt or thump when
shifting into Drive or Reverse or when accelerating or decelerating.
