anyone have any experiences with a shake/stutter in a 08 g35x at around 40 mph? can only feel it at around 40 mph and seems to occur more when car is started for 1st time. seems to be a shake/stutter, almost similar to the feel of a manual transmission. any thoughts welcome on what it could be. thanks.

 

Yes, many of us have experienced this. There was a long thread about this issue some time ago.
