#143 of 196 Re: Brake problem for 2008 CX-9 [vg33e power] by ceric Sep 15, 2009 (8:28 am)
Replying to: vg33e power (Sep 14, 2009 4:19 pm) 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.

#145 of 196 2009 CX9 AWD rolls back when on a hill by rpoddar Sep 19, 2009 (10:52 pm)
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 Replies to this message: bdyment (Sep 20, 2009 4:04 am) ceric (Sep 20, 2009 8:13 pm)

Replying to: rpoddar (Sep 19, 2009 10:52 pm) 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.

Replying to: rpoddar (Sep 19, 2009 10:52 pm) 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)
#148 of 196 Crunch/Squeek Front Suspension by vg33e power Sep 21, 2009 (9:51 am)
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? Replies to this message: howardru (Sep 21, 2009 9:56 am) k1200 (Sep 21, 2009 4:20 pm) vg33e power (Sep 22, 2009 6:28 am)

Replying to: vg33e power (Sep 21, 2009 9:51 am) 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?

Replying to: howardru (Sep 21, 2009 9:56 am) 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 Replies to this message: vg33e power (Sep 22, 2009 6:28 am)

Replying to: k1200 (Sep 21, 2009 4:20 pm) 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!
#152 of 196 2009 CX-9 transmission by chucky2 Oct 05, 2009 (12:50 pm)
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.
