#14 of 34 Mazda cx9 (2011) transfer case
Jan 09, 2013 (12:27 pm)
Very untypical of me to post reviews etc, but I almost feel that the problem I am having needs to be shared.
Transfer case failed at 3500 miles Whining sound at low speed (over 3 weeks in the shop…national back order)
Transfer case failed again at 16,000 miles. Whining sound at low speed
Transfer case failed again at 16,800 miles. Loud whining sound at low speed
Whining is still there, but I am now told after Mazda USA contacted dealer, that it is within normal range.
Mazda USA will not return calls (never has) I have been told by insiders that 2010, 2011, 2012 models all have this problem. Keep in mind that the only issue I had was a whining sound at low speed, not a physical failure, I was told each time that the oil turned in to sludge from over heating. I also understand that you may drive 20-30K miles before it physically breaks, so be aware, if you have one have it checked, if you are buying one....well good luck.

2011 cx9 14 months old, bought new....on 4th transfer case, and for some reason you think they make a great car??? The problem with Mazda is denial and lies, yes I have had issues with other brands, but never was I ignored as bad as I am with Mazda. Mazda USA claims they have no knowledge of any problems, and yet 4 dealers I called all said yes we have a lot of them coming in

I am so beyond relieved to have found this forum. Im new as of today due to an incident this morning. Long story short, this morning while driving the car to work, it seized at a red light after starting to vibrate. It then started again only to hear this very loud noise and then started to smoke. Scared, I pulled into a gas station (I know I know but I panicked) only to see men running towards me with fire extinguishers in their hands to put out my car that I didnt even realize was on fire!!!! The bottom was shooting up flames. Thank god no one was hurt. I was to find out later in the day that it was the transfer case. I looked into this a bit only to find endless stories of how this has been an ongoing issue with Mazda. My dealership has confirmed this issue stating they have rectified the problem. I drive my 2 year old twins around in this vehicle and I'd have to be on drugs to ever want to sit in it again especially when reading all of these stories about this being a reoccuring problem!!! I plan on contacting Mazda tomorrow in hopes on getting an answer as to why this was not a recall if they knew it was an issue. If I dont get this vehicle somehow reimbursed, then a law suit will be in play....I want to note this is a 2011 CX-9 and before today I have been nothing but 100% happy with this vehicle....If anyone wants to chat about this privately please let me know. Im sure it helps to know others are going through the same thing
#17 of 34 Transmission stutter
Jun 20, 2013 (8:18 am)
Hi, thought I'd appeal to the vast intelligence found in this forum on an issue I'm having with my 08 CX-9 base. Lightly accelerating on straightaway, around 30-35MPH, as car shifts into 5th gear, sometimes the whole car shakes. Doesn't happen all the time, mostly when 1st driving the car. Heavier acceleration and the problem does not occur.
Had dealership check it at 35,000, said they found no codes and couldn't dupe problem. Happens every day I drive it.
Any insight? Observing the tach, I see RPM goes up while shifting in each gear. When problem occurs, needle seems to bounce around within a range of a few hundred RPM. Almost like it is having difficulty picking a gear, or difficulty committing to next gear.

in the interest of information sharing to help anyone else with this issue... took into the dealer, they were able to reproduce problem as problem with torque converter. They recommended a transmission fluid flush, said sometimes it helps this issue. I said, is it covered under powertrain warranty, of course not. Was very skeptical, as this task is not listed in the service intervals. Further, they said Mazda doesn't recommend it. Despite my common sense, I gave go ahead, and $170 later, problem is fixed. I was prepared for a battle after the fluid flush didn't have an impact, but it did, and problem solved. They recommended getting it flushed again in another 45k miles.
#19 of 34 Dirty transmission fluid
Jul 02, 2013 (3:09 pm)
I bought my 2010 AWD Sport CX-9 2.5 years ago. About 6 months ago (at 17K miles), a local shop with good reputation told me the transmission fluid is "a little dirty". Today, when I brought it in for an oil change, I was told now the fluid is "very dirty" and he recommended transmission fluid flush.
After reading the posts here, it seems flush can do more harm than good, so maybe a drain and fill is better? Should I bring it to the dealership for a check up? It got me concerned since I love the car so far and would like to keep it for long time.

I just do a simple drain and fill on my cars but I've read that doing a "flush" where the engine does the work is okay. The power flushes using an external machine and maybe some chemicals are the ones that seem to cause the most issues (and may be overkill and just result in flushing your wallet).
Unlike oil, transmission fluid shouldn't look dirty so a second opinion would be a good idea.
#21 of 34 2008 CX9 engine & transfer case damage
Jul 05, 2013 (6:24 am)
4 days ago it made a funky fluttering noise on the right side of engine. 3 days ago, a high pitched whining started, off and on, then eventually just on all the time. 2 days ago I took it to the dealer who ran a diagnostic and the prognosis? immediate painful death unless entire engine and transfer case is replaced asap. I was stunned. never had any indication, no warning lights no missed oil or fluid changes, nothing. The sales/service tech said the sludge build up damaged everything to such an extent, that changing the oil now would do no good, I was too far gone for that. She also said I HAD to have a new transfer case but could get a used engine- for $8800. or I could get a new everything for $13,000. what a bargain. She was shocked when I said no thanks and came to pick it up. I asked her if this was a common issue with this model and she said no, but she wouldn't look at me as I spoke with her, she just stapled my paperwork with a lot of energy. I took it to another well known respected mechanic in town, who drove it around for 20 minutes and put it up on racks, ran a diagnostic, etc. and he said there was nothing wrong with the engine, I just needed to change the oil, (drain -NO flushing) and yes I did need a new transfer case- ASAP as it looked ready to quit, but a used one from a quality dealer would suffice. as predicted, my reverse went out last night which is the transfer case giving up the ghost so I am prepared to replace that (or just park in meadows). Before that I had the oil changed and it is already driving more smoothly and less deafening. My questions are: is this scope of damage a reasonable occurrence? How can an engine and PTO become so compromised and there not be any indication until complete failure is imminent? How can two mechanics see the same engine and come up with such drastically different conclusions? Why did the dealership service tech tell me I HAD to have a new transfer case when Mazda itself sells used ones on its website? I have purchased two cars from this dealership and never felt cheated or slighted, but that is not the case now. I want to be respectful of the fact that everyone is trying to make a living here and the dealership tech is pregnant and has an eye that is a bit wobbly so I don't want to stress her out, but I feel like I walked in there with a target on my back. Do I contact the owner or GM of the dealership and let him know? Does that do any good- ever?

I've posted elsewhere on Edmunds about this. There are known problems with the CX9 drive shafts, transfer cases, and brake bearings. Dig a bit and you'll find all the posts. I have a 2008 CX9 and just spent $4k on these items just to get it moving again. My car only has 79k miles on it and these should not fail. Multiple dealers have admitted these are known issues by Mazda and Mazda is choosing to ignore. Open up your checkbook if you are out of warranty on this one and I'll never buy a Mazda again.
#23 of 34 2013 cx 9 harsh engagemen in Drive
Jul 07, 2013 (11:32 am)
Just purchased 2013 CX 9. Noticing smooth transition to Drive until vehicle warms up. After that, all shifts to drive from Park. Neutral or Reverse are now alarmingly harsh. Car has 400 miles on it and will be returning to dealer for repair. Post will be updated as needed. Anyone else having this issue?
