#1 of 10 MAZDA CX-9 Whistling Noise by winstone Nov 25, 2007 (6:52 pm)
I have a 08 GT CX-9 for 2 weeks now. I noticed that when I park the car and stand by it, I can hear a very sharp whistle-like noise, sounding like from the bottom. The noise is much less noticable when sitting in the car and have the doors closed. Does anyone have similar experience?

Replying to: winstone (Nov 25, 2007 6:52 pm) Our 07 GT also has had a barely audible high-pitched whistling noise since we bought it last February, but only at idle. We had a '99 Jimmy that had the exact same noise, and I think it was related to the fuel pump or the fuel delivery system, but didn't affect the way it ran. I may ask the service tech next time I stop by the dealer, but since it's not very loud, I usually don't think about it... Replies to this message: winstone (Nov 26, 2007 4:54 pm)

I have heard the noise coming from other models of cars (Nissan, Toyota, Honda.)   If they key is not in the ignition, some cars may run some fuel-evaporation checks a few hours after you turn it off.

#5 of 10 Driving my cx9 in the snow. by bluemom Dec 20, 2008 (5:57 pm)
I live in Minnesota where we just had 5 inches of snow and my Mazda CX9 is a joke and a hazard in the snow. I don't know if is the tires or the awd not working correctly. I went through 3 stop signs today, and I can barely get up a very small hill. This is not normal, and I really don't know what to do about it. Any suggestions, or has anyone else had this type of problem? Replies to this message: howardru (Dec 21, 2008 8:42 am) bluemom (Dec 22, 2008 6:36 am)

Replying to: bluemom (Dec 20, 2008 5:57 pm) You are FAR from alone. The reviews of the stock tires on the CX-9 with snow scared me to death. Comments like "Mazda should be sued" and "worst tire ever labeled as all season" etc.... Check out the reviews on Tirerack.com and this thread below:   http://www.mazdas247.com/forum/showthread.php?t=123727584   or this thread   http://www.mazdas247.com/forum/showthread.php?t=123687031   Many of us bit the bullet and ponied up $1400 for new Blizzaks, rims and TPMS to install. Just put mine on last week in time for the snow here in the Boston area for the last week and am very happy I did. Been working really well so far.   Tire Rack will put them on rims, balance and ship them to you (or local shop) for installion. I went down a size to 18" to save over $100 per tire but kept the same diameter so the speed/odomoter was not affected (P235/65R-18 Bridgestone Blizzak DM-Z3) on Sport Edition ST3 rims.   Get those stock tires off your car quickly!   Merry Christmas from Mazda!

Replying to: howardru (Dec 21, 2008 8:42 am) Thanks for the reply! I just talked to mazda and the dealer and they are basically saying that I probably need some new snow tires, I only have 14,000 miles and they are not taking any resposibility towards selling terrible tires on this car. I haven't had to get snow tires for 20 years. This whole thing has left a bad taste in my mouth. Mazda should recognize this problem, and address this. I guess I have 2 choices..new tires or drive and pray on the existing ones.
#8 of 10 Mazda CX9 Tire Noise-Pirelli tires by rjjbash May 05, 2009 (7:21 pm)
We recently bought the Pirelli Scorpion tires at 30,000 miles for my 2007 CX-9. Its been 4 months and probably 6000 miles and there is now a loud humming noise, which the dealer thinks is tire noise. Is anyone having problems with tire noise on these vehicles? I went back to the tire store and they put on a Goodyear Wrangler and still had noise.

Replying to: rjjbash (May 05, 2009 7:21 pm) I'm curious about the scorpions... it's been about 12k miles since you've had them... ( estimating )... how do you like them? Do you use them much in the snow?
