Infiniti G35 Forum : “G35 strange vibration”

could be a tire out of round.i would take it in for a alignment and have it checked for ant worn out parts.

Thanks for the advice. I was told it might be the transmission. It shifts fine so I doubt that is the problem ( will have the alignment checked first). It makes a helicopter like sound when it happens and the whole car vibrates It's not consistent though. 9 out of 10 times it shakes then every now and then it does not. I will get to the bottom of it and let you know. Thanks again for the advice

yeap it might be something internal in the tranny, a friend at work got rid his G35 because of this, his co-worker bought it. turned out it was the tranny

Driving home it started to drag - big hole in the brake caliper. dealer was good about got two new rotors and pads all around for free - but it still has slight vibration in the front. Guess I neen to add a cool picture like you guys
