Good morning guys.
I have noise (large thud ) that comes when i start my car (not always just when the weather cold and cool plus leave the car without using for a while).
cold wather or cool + the car sit for a while + first start = thud (noise ) .
Cold weather + the car not sit for a while = no noise .
warm it starts without noise , warm means more than 60 F.

These video today , listen to first one has the noise (like hit under the dash or under the steering wheel) large thud. It happens to only first starting if i would turn off directly then turn it on then will start normal). By the way its 2004 g35x sedan.

First video has the noise. First starting.





second video ( normal starting without noise ) .





thanks guys in advance
