    And I believe most of the problems you experienced are related to an electric short somewhere that the mechanic/tech has not been able to nail it down.
    If I were you I would find another more capable dealer or call Mazda directly.
    A spuradic short could cause all kinds of strange problem in the system. :mad:

    Very likely than not, it could be one of those port-installed accessories:
    auto-dimming mirror, sat radio, iPod interface, remote start, etc. One that relates
    to wiring but not installed at Mazda factory. (Actually at port of entry - LA for west coast)

    Mine has 17,000 miles on it. Only 1 problem with window refused to roll down (styrofoam got loose inside - easy fix at oil change). Mine was probably made on Monday when the worker was still drunk from Japanese sake. Just kidding. ;)

    2008 CX-9 with over 3,000 miles. When running AC with recirculation button, there is a musty or moldy smell. The dealer said that it was the cabin filter behind the glove compartment, and their tech changed it. Unfortunately, they also added an equally foul smelling perfume substance to hide the original smell. Now, we have to deal with the unpleasant perfume as well as the moldy odor. Apparently this happens a lot after the vehicle was sitting on the lot for many months before being sold.
    Any suggestions??

    I agree with you ceric, but I only wish I had those options... I do not have sat radio, ipod anything or auto dimming mirrors....I added nothing, changed nothing. I do like my Mazda, but man oh man am I tired of the quirks.
    I could use the sake' myself ;)

    This used to happen in my old car, basically the air inside the vent would condense into water and just sit there, which was a perfect situation for mold to grow (cold air inside the vent + hot, humid air from outside that makes its way into the vents = condensation).

    What I started doing was simply turn off the AC a minute or so before I would shut off the car and just blast the air on High, just to remove the cold air from the vents and minimize the chances of having condensation (leave the windows down, or else you might get condensation inside the cabin). Never had a real issue after that. I also notice that our CX-9 was starting to smell musty like your with the AC, and started doing my old routine and we haven't had an issue yet.

    You could argue that it would be better to blast hot air after shutting off the AC in order to really dry out the system, but that's a form of torture if you're sitting in the car on a hot summer day!

    I have a 2009 cx9 for 1 mo. Today I was told that loss of signal is typical on sat radio by the dealer. This happens intermittenly, not just in tunnels or under overpasses. I've rode in other cars and it doesn't happen as much. Is it the quality of the radio or they all created equal??? Anybody else with this problem. Other than that love the car.
  • OMG, I am new to this forum and I am so glad I'm not the only one experiencing these problems with the '07 CX-9. I thought I had purchased the lemon of the lot, but it sounds more like an epidemic vs. unique problem. I have the loud clicking noise with brakes and the internal fan coming on when I turn the ignition off.

    My lease is up next year and I was hoping to purchase it thereafter, but I think I too will be trading it in. I don't know where else to look for a reliable 7 seater. I know Toyota just came out with there's, but I'm sure it is big $$$$.

    Perhaps not as much but it does happen! My understanding is that satellite reception problems are fairly common and are caused by several factors including variable quality of antennas and receiving equipment, local repeater stations, signal quality and so on.

    I had my CX-9 checked second time by another dealer for front knocking noise when driven on rough roads. they had my car for two days but still couldn't solve it. They called Mazda and were advised to replace struts. For me it's hard to believe brand new struts failed within 2-3k miles before tires. Seeing your post, I'm further convinced that the struts are not the source of the problem. So I asked the dealer to leave the case open for future replacement. The noise doesn't bother me that much, so I will keep driving to see how the problem develops or maybe mazda will come up with a TSB to address this. This is my first mazda and I've already started to loose faith in its reliability. So far this is the only problem I noticed and hopefully there won't be more.
  • cericceric Posts: 1,093
    1st year production of any model has typically more issues. As production goes on, problems got solved and TSBs got issued. There are TSBs on both front and rear brakes. You should have the dealer look at them. The fan issue also is well-known to be some faulty switch. If I were you, I would have them fix them. If they couldn't, I would probably return the lease as you said.

    I *think* I have a heat problem as it sometimes gets really wiggy, quits in the middle of prompting all on its own, etc. Other times its solid. Usually good in the morning, bad in the afternoon...oh, did I mention I live in Dallas? it gets a tad warm here even in the shade (IF you can find any)...Dave ;)
  • Just got cx9 today...
    the windshield haze does not seem to go.
    Used to my toyota...just putting full a/c on windshield removes the haze.
    But not working in cx9...any suggestions ?

    Thanks!
  • wdhytewdhyte Posts: 92
    Got a new problem/oddity...maybe? here's the scenario...
    just came home and had all the windows and moonroof open for breeze (2115 CT approx)...it's a wonderful 80 deg F here in Dallas (FINALLY!) so was taking advantage of it while we can! ;)
    had the A/C off, recirc off, to pull fresh/cool air in to the cabin and it was great...BUT, in th rear it was blowing at least 10 degrees hotter than the front vents. Turned the front control (and rear) all the way down as far as they'd go...was reading a setting of 60 deg for the system setting...the air coming in the front vents felt like the outside air BUT, the rear still felt warm...still at least mid 70s if not warmer...if set the system for rear control, it got even hotten...shut off the rear control, and it was cooler but nowhere near what we were feeling in the front.
    ideas? suggestions? TIA...Dave
  • No definite suggestions. But I am not sure there is a problem. (I know this is not what you want to hear.)
    We live in Colorado (not always cooler but lower humidity). We notice that the front vents (with a/c and heat off and temps down to 60) blow air that is never as cool as the outside air. The rear vent system blows air that is slightly warmer than the front vents. We just assumed that the rear vent was not really designed to vent air from outside, but to assist cooling the rear by a/c or heat the rear with active heat ( both of which it does very well).
    We don't know for sure but have guessed or assumed that Mazda's design is flawed. The front vents are probably influenced by the heat from the engine and the rear vent has an additional distance to transmit the air; therefore, allowing it to warm even more. We have learned to live with it. It does help a lot to open the roof. But we run the a/c almost all the time. If your rear vent does not cool with a/c then there is a problem. Our grandchildren frequently turn the rear off when I run the a/c because it is too cold for them.
    We have owned many vehicles and never noticed a problem with the outside air until the CX9.
  • My question is for ceric, mazdatechie, or anyone that has access to a shop manual. I just bought this used 2007 CX9 and I noticed that the glove compartment has a "damper" on the right side that attaches to the door of the glove compartment to perhaps prevent the door from just flopping open. Mine is unattached and I tried pulling on the little arm to re-attach it but then noticed that it may be broken. Is this damper easily replaceable by removing the glove compartment door off and accessing it that way or does it require removing half the dash to get to it? Any help would be appreciate it. Thanks!
  • cericceric Posts: 1,093
    On the right side, there are two things that prevent the glove compartment door from dropping, the stopper at the top, and the linkage arm/damper(?) at the bottom.
    I assume that you're talking about the lower one. I don't know what you meant by "broken", but mine (supposedly not "broken") is merely hooked on to the round head on the door so that it holds on to it. It is quite loose (wiggling) but it does the job it is supposed to. There is no "damping effect" as far as I can feel.

    Anyway, if indeed it was broken, the dealer would know if there is a separate part number for the linkage arm. If not, you will need to buy the entire ensemble. That would cost you $$$.
  • Thanks ceric, I should have been more descriptive. The little arm that come out of the dash and would clip in to the round little head molded into the door is what is unattached. I pulled the little arm out because it was tucked into the slot in the dash to connect it to the door but I noticed that the end of the arm has a sort of thin plastic swivel looking piece that I would imagine would go around the tiny head on the door and snap to lock it in place. Is this the way its suppose to be or is this piece broken?
  • Did anyone find out the culprit or did Mazda issue a TSB for the front knocking noise when going over bumps? Seems that my 07 CX9 has it as well.

    My previous 06 Mazda5 had the same noise and was fixed via a very well known TSB for Mazda5's about the noise in the fromt or rear suspension. The culprit was the sway bar bushings. Mine were replaced and I never hear another noise out of them. I wonder if the same applies here to our CX9's??? If that is the case, is Mazda contracting the same vendor to make its sway bar bushings for its entire line-up???

    Any help?
  • I bought at 2008 CX-9, 33000 miles, about 3 weeks ago. When we went to the mountains last week, there was a problem with the brakes going down hills in all of the I-70 traffic. They were pulsing, that is the only word I can think of to call it. Before this I had a Subaru Outback, that also did this, but not until there was 75,000 miles on it. Has this happened to anyone else? :confuse:
  • I take it you bought your CX9 used... If you bought your CX9 from a dealership take it back to them and have them check you brakes. Sounds like they have to resurface or replace your rotors as well as inspect or replace your brake pads. If you bought it from a private party looks like you will be dishing out some money to replace the above mentioned parts. Good luck!
  • cericceric Posts: 1,093
    Are you sure that the problem (pulsating braking) only happens going down hills?
    If the rotors needs resurfacing, the problem will show on any road surface, not just down hills. It could also be the tires getting bold. The OE tires (if still on your CX9 - Dueller H/L 400) are so-so tires (to put it mildly). It has wear index of 260, which means it lasts about 26K miles in my book.

    The bottom line is
    - check the tires if the problem only happens on down hills
    - check the rotors (need resurfacing - so-called warped rotors, a misleading term)
    if the problem shows on any surfaces.
  • Ceric....Mazdatechie......

    Any help on this issue???
  • We have a new 2009 CX9 GT AWD, and recently we took it to San Francisco. We noticed that when stopped at a light on a steep hill (going uphill), the car starts to roll backwards when we took out foot off the brakes. Is this normal, or is there a way to stop it? FYI in my 99 BMW 528i, we never had this problem. I thought AWD would never allow this kind of issue to occur.

    Thanks
  • bdymentbdyment Posts: 551
    AWD has nothing to do with rolling backwards. Keep your left foot on the brake and give the engine a little gas to counteract gravity when releasing the brake. Some automatic transmissions simply roll back easier than others due to engine and transmission setting. There is no way to manually select AWD.
  • cericceric Posts: 1,093
    Use foot brake may help.
    Hand-brake would have been better/easier, but most SUV/CUV don't use hand-brake (occupy center console space)
  • Sorry to keep bringing this issue up, but I want to see if I can get an answer or perhaps to see if someone else is experiencing this as well, the noise is driving me crazy.

    My 2007 CX-9 2WD Touring makes a crunch/squeek noise that seems to come from front suspension area. It seems to make it only when traveling at slow speeds over speed bumps and going in and out of driveways. The noise may be there all the time but it is only noticable when driving slow under the circumstances mentioned. My 2006 Mazda5 had this similar noise and Mazda had a TSB for sway bar bushings which remedied the problem, but I cannot find any TSB relating to this concern on my CX-9.

    Does anyone know what the problem is or the solution to it? Is anyone else experiencing this noise/sound?
  • Mine is driving me crazy with a sqeeky noise coming from the sub-woofer area when going over bumpy old roads (lots of those here in New England).

    I lubricated every seat bolt in the back of the car yesterday and finally narrowed it down to somewhere below where the sub-woofer sits in the trunk. When I bang on the cargo mat above the speaker, I heard the squeek!

    Ceric, do you have the instructions for removing the plastic cover over the sub-woofer?
  • k1200k1200 Posts: 40
    I have a 2007 CX9, and I know I have posted many problems I had, mine is a AWD and that sound drives me crazy to put it best it honestly sounds like I am piloting an old wooden boat. When I turn at slow speeds 20 mph or less it sounds like boards bending loudly. I have taken it to 2 different dealers and what I get back is a vehicle covered in lithium grease and they say "nothing is wrong" I still have the issue of turning the car off and the interior fan front and rear come on full blast (even though they were never on to start) and runs for about 4-6 minutes. It does not matter what the temp. outside is.
    The mechanic told me "its the car trying to (auto cool) itself" ....note to mechanic there is no such feature on this vehicle...and if it did why do it when its 31 degrees outside ?
    I could go on and on, but I am not here to badmouth mazda.... I just wanted the things fixed... :-( (C)ar (X)perimental 9
  • K1200,

    I guess we will continue in the search for the mysterious squeek/crunch noise resolution, but to help you out on your blower fans coming on after turning off your vehicle here is what I posted on the ventilation forum:

    "My CX9 is out of warranty so I asked my buddy that works at Riverside Mazda to hook me up with a copy of TSB 07-008/09. I read through it and was very simple and straight forward. I bought the relay that the TSB said to replace (part# G115-67-730) replaced it (under hood relay box closest to the driver's side fender) and up to right now no more occurences"

    There are three fuse/relay boxes under the hood. 1) small slim one on the very front attached by the radiator. 2) Main fuse box on driver's side (the biggest of the three). and 3) Relay box right next to the main fuse box closest to the driver's side fender.

    Relay box #3 is where the two relays for the front and rear blowers are. They are the biggest realys in there and they are probably black in color. Both relays are the same number, so be sure to buy 2 of the part number I provided and replace them both. The new relay should be a light blue color. Hope this helps you.

    Now lets get back to trying to figure out our suspension noise...Ceric? Mazdatechie?

    HELP!
  • My 2009 CX-9 has 3500 miles on it. The transmission already went bad. First my dealership says it's the transmission control module, now they claim it needs a whole new transmission! It has been in the shop for 3 weeks, now I get to wait for a new transmition to come in. Anyone else have transmission problems. Zoom, zoom...what a joke.
