There is a nasty rattle in my M35

[mmaciej]

Somewhere between the first and second gear change there is a nasty rattle coming from somewhere. I originally thought it was the transmission but Infiniti ruled that out. It happens intermittently, but it happens. Does anyone else have this problem?

Does it happen only when its cold? I know that Nissan/Infiniti have problems with heat shields. Mine was making alot of noise when idling.

No it happens most often when I am accelerating from a stop, and espcially when I accelerate into a right turn.

Is it coming from the engine compartment? Below the car? Somewhere else?

Sounds like something is loose ...

I HAD THE SAME PROBLEM...ONE DEALER COULD NOT FIND ANYTHING WRONG BUT ANOTHER ONE FOUND OUT THAT IT WAS THE MUFFLER CLAMPS THAT HAD RUSTED OUT..I THOUGHT THAT NOISE WAS COMMING FROM THE ENGINE...

time to break out the wrenches and tighten things up. I do that every once in a while with interior parts and below the car. Keeps everything tight.

I had a rattle once. I have aftermarket wheels on my car. I first thought the noise was coming from the center caps which weres loose. Come to find out the noise was coming from the stainless steel tailpipe tips which were loose.
