CX-9 Resonant Vibration by lch77

My new CX-9 GT AWD has a mild engine resonance vibration that starts around 2000 RPM and goes away at around 2600 RPM. I can feel in in the steering wheel and the pedal. It sounds like fairly normal engine sounds during accelaration and if it were there throughout the entire RPM range, I might think it is normal, but it comes in and them goes away in the above range and is the same no matter what gear the car is in or speed it is travelling.
 
Does anyone else notice this?
 
I haven't brought the car in for its first service, but I'm expecting the dealer to say that it is normal since it is probably difficult or impossible to fix/change.

yup- and I've read a few other posts just like this so I'm expecting it's "normal". Watching each one to see if anyone gets any dealer response. None as of yet.

I have a '08 GT AWD.
I don't feel any such problem on mine.

Just went back from dealership. Technician told me that is an open bulletin in Mazda. Some one reported already. They ask dealer do not do any fix until further investigation.
 
I start to wondering if this happen to most of 08 GT AWD?

Just got a call from local delaership in San Jose. They said Mazda corporate told them that they have found a way to fix it. They asked me send my CX-9 in tomorrow. And their technician will use hot-line to get instructions from Mazda corp directly to fix the problem. Will see how it turns out.

Picked up my car hour ago. They fixed the problem apparently. No more vibration at 2000rpm. The engine now is silky smooth any time.

Hi, spi5:
Is the dealer OakTree Mazda?
There is a slight vibration around 2000rpm, but not enough for me to call it an issue.
If they can make it smooth, why not?
 
I hope Mazda send a TSB to all Mazda dealers so that all customers can benefit from your experience. Thanks.

I went to Capitol Mazda. You may call Jared in service department.
 
The vibration actually did not bother me a lot except my wife complain about it. I sent in my car without any expectation since it is just a not big problem and thought it might be difficult to fix it. However, they fixed it! Nice work from both dealership and Mazda. I will keep being a loyal Mazda customer (Tribute -> RX-8 -> CX-7 -> CX-9).
 
Feel great on ultra-smooth Zoom-Zoom now.

Our new 08 Touring FWD has the same vibration between 1,700 and 2,000 rpm. I feel it in the pedals both accellerating and braking. Do you have any specific technical reference on your paperwork that I can tell my dealer about? Any other info on HOW they fixed it? Thanks.
