I have a 2000 Gs400 and everytime i accelerate from a stop i hear a rumbling noise from behind the ac vents. Even when i put the car in park and slowly rev the engine you can still here it on low rpms. The only thing is that it only does it from like 500-1500 pms. After that, it will never do it. Any ideas???

My car also makes a noise when I accelerate from a stop. Usually it only happens when I have the AC on. I wouldn't say that it makes a "rumbling" sound, it isn't that deep. Mine almost sounds like there is liquid transferring back and forth when I stop/go.

Is this similar to what you are hearing?

Maybe it's crap in your glove box sliding around? That's been a source of noise in my car before.

I had more of a gurgling sound.

It was air in coolant system.

Hope that helps.

Yeah I had my gurling sound checked out at the dealer & they told me it was definitely the air pocket In radiator. It was also confirmed my Mo at SRT.

if it is an air pocket can i get rid of it by just opening the radiator cap and closing it?

Hey guys... Well, mine makes a gurgling noise too but it does not sound like it is water. I will take it in because it is very annoying. And it is not from my glove box because my glove box is empty...
