Have had my new Z for a month. I have noticed a rattle under the dash when the car is cold (no rattle when warmed up). The dealer has been very responsive, but there is so much plastic, I am not sure anyone will be able to locate the noise!!!!
It's a beautiful automobile, that brings new meaning to filling up at the the local gas station without being asked multiple questions by multiple people.
Have any of you experienced this rattle as well?

 

I have the same problem, car is garaged, for the first few minutes every day I have to put up w/ the rattles fom the front as well as the rear. I am reluctant to let the dealer fool w/ it for, they could make matters worse. Someone mentioned it could be wires directly beneath the dash.

 

Thanks for responding. I agree it might be wires or it might be the fit of the plastic connections of the under dsah as well. The next time I go into service I will ask them just to check the connections and not take anything apart.
