Hi all,

It's 93 degrees outside here in midwest, and I'm constantly struggling with rattles and other noises from my 08 g35x.

Though I've taken care of many of them, I still can't find the sources for the rest. So I was wondering if there's anyone out there with some further insight on these issues.


I have a buzzing sound on certain conditions of roads.
It's really hard to explain, but say I was driving a rough concrete surface, I would have a buzzing sound from somewhere around center console or possibly from passenger side front dash.
It's really hard to pinpoint where exactly it is coming from, but def., from inside around dash.
Now... from the fact that it is not a rattle, nor a squeak, I think there's a little spring-like piece vibrating somewhere.
I've seen a thread from another forum (forgot where it was, but it was a forum for a car with a push-ignition system just like the one in g35) about a buzzing sound from the spring attached on the ignition button itself, therefore the noise travels around.
He said he fixed the problem by attaching Dynamat or similar anti-vibration sheet on the spring.

Here's the question..

Is it possible for g35's ignition system to have a vibrating sound cause by the little spring inside there?

I mean.. I've seen the diagram for that part, and didn't see any spring part attached to it. And honestly, since I'm no expert so tearing up that part would be such a hassle for me. (and no, I wouldn't let dealer do it because everytime they re-assemble that certain part, they would make another source of rattle)

I would really appreciate it if someone can tell me if ordering a Dynamat sheet AND going through all that assembling task would fix the buzz.
Is it worth trying?
Anyone have an experience looking into that part?
Is my guess likely to be right?


One add-on question..

Has anyone experienced a buzzing sound around the navigation screen?
Possibly from a spring inside there, which I doubt there is any springs...
Any other possible source for buzzing?

 

i have it when applying light throttle from a stop to the left of my speedometer/tach console..definately a buzzing. Goes away after a split second

 

Have the dealer check out your homelink mirror. I took my car in for a buzzing sound and they found that the mirror assembly was loose which caused a resonating effects toward the windshield creating a buzzing sound as if though they are from the dash.

Try this: when you hear the buzzing sound, hold your mirror securely to see if the sound diminishes.

 

befree112,
thanks.. I will give it a shot.

did you heard the noise on rough pavements? or randomly?

 

Yea, the noise that OP described is exactly as my car is having. It is from the Driver side console, dash. I sometimes hear the noise when I turn the ignition on to start the car. And there is no way I can re-create the noise, it comes randomly and mostly on a rough road. My car is 05 Coupe.
