strong vibration on Neutral and Parking
 

Hi,
I own Mazda3, the 2.0L engine tiptronic gear. The car is 2007 model. After around 8000 km, I started to feel strong vibration when the gear is on Neutral or Parking.
This vibration feeled especially on the legs and whole the front seats. It vibrate the same as the engine when you touch it as it works. The local Mazda representitive told me that this problem is new here and, he sent the letter to Mazda corporation to get the answer.
Did someone of you noticed somewhen about similar problem?
It realy annoying when you stop the car and feel like in old diesel car :tear:
