Re: Slight clunk/thud when I get off brake and gas it.
Mine is an MT, and I don't hear any clunk so for.
But I used to have the same problem on my Infiniti G35 Coupe. Whenever I downshift to accelerate or get off from a dead stop, I heard a clunk from the rear. Then I found out it was a rear axle problem. There was even a TSB for the G35 Coupe, it stated that the Wheel bearings were not tightened/torqued properly.
Is it from the front or from the rear? Do you hear clicking sound when backing up on an incline? It could be the bearings or just some normal noise. Best way to find out is take it back to the dealer and have them take a look at it.
