I'm sure I'm not the only one, but to share.
Between 70-75k I experienced a slight/brief vibration during deacceleration and a clunk upon acceleration.
What was found was a broken driver side motor mount. 1)This causes the noticeable vibration as the AFM controls the deacceleration from 4CYL mode back to 8CYL mode, which occurs between 22-20MPH in anticipation that the motor will again accelerate after slowing or stopping. 2)This also causes a noticeable clunk when re-accelerating.
Transmission was serviced as a precaution but checked out fine. We had already test drove the vehicle and somewhat ruled this out as a possibility when we placed the gear into Neutral and there was no vibration or clunk.
I live in the PHX area and don't know why with low mileage or 6yr age under normal limited driving city/hwy conditions the motor mount would fail? The vehicle is garaged more than it is driven or sits out in the grueling heat during our lovely summers.
