2012 V6 Performance Package (Vibration at 2500rpm)


Today I noticed that on the highway, while accelerating in 4th , if I let the rpm fall from 3000 to 2500 naturally (taking foot off gas) I get a strange vibration – seems like whole car is shaking. When the rpm fall below 2200 or so it stops. I reproduced it repeatedly. Speed was 80 kilometers an hour in 4th gear.


It feels exactly like when your wheel passes over (rumble strips) those grooves on the edge of the highway that alert you that you are departing from your lane (the horizontal ones that are very close together and look like tracks)

Apparently the Dual Mass Flywheel is to blame for this and it seems to be fairly well documented :

What does everybody think ?


I have also felt this at time at low speed on the street, but very rearly.


Should I be concerned ?

Thank you.

 

It's nothing to worry about.

Shift gears if it bothers you very much.

 

I forgot that cars are not allowed to have any feeling or sound that feeds back. it really does sound like normal operation.

to be honest I would be worried if I was in a sports car that had no sound or feedback.

when I installed my axleback my wife asked if the car was broken because it sounded loud.

 

Hello,

Thank you very much for the answers.

Thank you.
