Weird rattling/vibration noise under the hood, drivers side

Hey guys,

New to this forum, but not to online forums so we'll put the n00b attacks to bed right away. (lol)

Just purchased my 2nd Mazda 6, this one being the '09 GT V6 and absolutely love it. My only issue with it so far, is this very weird noise under the hood that comes on and off intermittently and have done everything to try and figure out what it was. Take a trip back to the dealer as I wanted to rule out anything major, and the technician there tells me that this type of vibration I am hearing comes from the A/C unit whether it's on or off, and was and still is a common problem with the CX-9 line. I asked him if their is a fix for it, his response was no and that I would have to live with it. An easy thing to swallow if you paid next to nothing for your car, so I don't need to go into detail how much my GT V6 with every available option you can get without the NAV cost me.

Now while I agree this isn't a major problem, I'll admit it's freakin' annoying when you are driving and don't necessarily have the radio going as you can hear this pump or whatever it is kicking on and pulsating for a few minutes, only to have it shut off and start all over again.

Are their any other '09 Mazda 6 owners in the V6 family experiencing this same type of noise? If so, did your dealer offer a fix or were you told the same thing whereby you have to live with it and should just turn up the radio so you don't hear it?

Cheers,
 
I think I have the same noise, however, mine sounds more like a rumbling and only occurs when the car is idling.
 
I had a similar problem in my previous car (330i BMW). It ended up being a heat shield on the exhaust that had made its way loose.

Can you hear it while idling with the hood up?
 
I have a 2009 v6 GT as well and my was having the same problems and left it with dealer for a month and finally, they got it fix. email me at mclarenf11975@hotmail.com with your contact number and I will provide more information for you. Thanks!
 
Purge valve made the weird noise

Have the pull out the same 6 that you have and park together with the engine on and the hood up as well and idle for about few mins, you should be able to hear the sound somewhere around the stupid metal piece attach with the intake host.
 
I have the same problem

I have a 2009 MAZDA 6i Grand Touring and just posted the same question above. Mine is a vibration at idle and it is annoying as hell and I don't want to be told to live with it either.

MAZDA must address this problem or I will contact my close friends in Congress !
