#105 of 547 Fan tuns on after CX-9 is turned off, wind noise on driver side door/window
Apr 13, 2009 (1:24 pm)
I had the 2007 cx-9 touring (no bells) for about 18 months and for the most part am very happy with it.
Recently, my fan has been going on at full blast as soon as I shut the cx-9 off. It seems to be from the center console housing the rear AC controls/vents. I have not yet taken it in since it occurs sporadically so it's pretty much impossible to replicate at any given moment. I have tried to change settings before turning the cx-9 off so I can try to figure out the cause, but I have been unable to figure out if it's being caused by certain settings. I saw an earlier post where the relay was burned and that was causing the issue. Has anyone else had the issue or any new diagnoses? Will mazda cover the fix?
I also have a lot of wind noise from the driver door. You can hear it from about 30 mph and up. I know there was a recall a while back for a door issue, and I supposedly had that fixed, but I still hear the noise. Any one else have the issue or any thoughts?
I plan on taking it in to the dealer, but I would like to have as much background info as I can before I do go in.

The door recall was for the door stopper, not for noise if I remember correctly for 2007 models.
The A/C issue (full blasting) has been reported. Some electrical problem for sure. You should take it to dealer. If CX9 is within 36K, there is no reason that dealer won't fix it. Some dealers even give you a loaner for repair works.
#107 of 547 Front Suspension Problems??
Apr 15, 2009 (7:20 pm)
Have a 2008 CX9 with around 16,000 miles. Noticed lately that when I drive over speed bumps, turn wheel while pressing brake and/or driving over bumps in the road at certain speeds, that I am hearing and feeling a knocking sound in what feels like the front right strut or brake. What could be the problem?

I have a 2008 with just over 18K. I had the same thing recently. I checked underneath and found that an end link to the front sway bar was loose. One of the nuts had worked its way loose. I tightened it and all is good now. If that is the case with yours you need a 17mm wrench, but you also have to have a 6mm hex key in the middle of the bolt to hold it while you tighten the nut.

Same here... Mine is a 2007 about 43k on it... I never abused it at all, I like the vehicle but , boy have i had some issues. That knocking noise, had a tech ride with me. He said he did not hear anything. went to another dealer... all they did was put lithium grease on anything that moved (did not help) I am not going to bad mouth the car or the techs, I do think most of them are really good, but so many times I got the run around and the electrical problems, the cd player, the ac, the interior fan that came on when you shut the car off.......... argh

Thank you so much for your reply!!! I was about to take it in on Tuesday to find out what was going on, but thanks to your reply I found the problem. It was not the end link or any loose nut, but it was 2 grape size rocks/pebbles that had found there way between the sway bar and the frame....unbelievable! Thanks to your reply I was checking the link/sway bar and just happened to notice the rocks.

Folks / Update
Unfortunatley, we are still having problems with the engine knock / rattle.
(very good recording of engine knock / rattle noise can be found at link below)
I have taken it to our dealership three times with no luck in fixing the problem. On the last trip, the dealership kept it for about a week and a half and concluded they could not hear the problem. They told me they had Mazda reps drive in and could not hear it either. Overall, communication to me from the dealership was very poor, but that is another story for another day. I told them I would record the noise.
So now I have the entire thing on video, as well as a very good recording using a USB microphone fixed under the hood. For those that are interested and think they can help, you can get the recording as an attachment in my post here (noticed Edmunds doesn' t allow attachments beyond an image; otherwise, I would have just uploaded to this message):
I contacted Mazda Corporate through their 800 number earlier this week, but I have not heard anything from them since that time. They did mention they would call me to coordinate sending some folks out here to ride in the car. They said to not contact the dealer and to wait for them. I told them I had a perfect recording and video and happy to share to help them diagnose the problem, but again, I haven't heard anything yet.
My questions are:
What to do next?
Does Mazda back their vehicles and support their customers?
Any ideas on what the noise could be?
Anyone else with this noise (some have chimed in here - thank you - is this the same noise you heard on your vehicle)?
Any and all help / advice VERY much appreciated.

My engine tap does not seem to be as bad as yours, yet? I brought it in for service 4/20/09. I was told the tap is the fuel injectors. I was told they "loosen up" after a while...nothing to worry about. Not so sure about that. I will keep an eye on it.
I did have the airbag recall fixed.
Mazda knows about the rear fan going on when the car is shut off. There is a part to fix it but it is on back order.

Rudio: All I can offer from my problem is that it has gotten progressively worse. Hopefully your problem is unrelated... ?
Also, I did hear from Mazda Corporate today. They are sending out a regional technical specialist on Tuesday to look at the vehicle. I have provided him with a copy of the recording and will provide him with the complete DVD + full recording on his arrival Tuesday.
I will continue to keep everyone updated on my progress.

First let me say that was a very good recording.... im not a tech and i definitely heard it. When this happens, is there a loss of power ?
Could be a few different things... valves, rings, something thats called "piston slap"
I hope it is something that can be resolved without much inconvenience to you. I personally have had my own issues with my vehicle, and to this day continue to have on going issues. I dont know why they cannot be resolved. I do like the vehicle..but I cannot stand the fact that every 2-3 months im in with the same or more issues. I will probably sell it in a few months
good luck keep us informed
