When getting off highway engine began to knock. Engine stalled and would not restart. Upon inspection the water pump was found to have failed and leaked engine coolant into oil. This caused engine to have a complete failure. No check engine light illuminated but when car was scanned multiple codes were found. The car was also found to have a bad Transfer Case.

While driving the car on a county road, with the speed under 40 mph, and following the bend in the road to lead to getting on the highway, the car jerked forward as if I hit something. As I continued to drive, the car was making loud clinking sounds and was jerking in motion. No warning lights went on. While attempting to continue to drive, clanging noises could be heard and the car continued to jerk forward. The car was unable to be driven. After having it towed to my mechanic, it was determine the problem was the transfer case. The splines between the transmission and transfer case had been eaten away by rust. The seal had not kept water out as it was designed to do. A new transfer case was ordered as well as a new transmission. The replacement transfer case had shown signs of the same issues with the splines. Another (2nd one) transfer case had to be ordered. I had purchased this car in February 2019 used. The car had a clean title, no accidents and was serviced regularly. Within 1 year, I had to pay out $5,000 to replace transfer case and transmission. I lost the use of my car for over 3 weeks (due to the problems with getting a transfer case that was good). When you google this issue, many people have had similar issues.

The transfer case in our 2011 Mazda Cx-9 failed at 130,000 miles. I understand that Mazda know about a defect as to the proximity of the transfer case to the exhaust. The heated transfer case lubricant become sludge-like and causes the case to fail also affecting the transmission splines. The heated lubricant escaped and drips on the exhaust and fills the vehicle with a toxic smelling gas and apparently can light on fire. The transfer case failed while driving making getting out of traffic difficult. Mazda issued a bulletin in 2014 extending the warranty to 7 years or 90,000 miles but didn't inform any of the customers of this problem. There is no service schedule for the transfer case as recommended by Mazda. Or any way I understand to change the lubricant in the transfer case. Without informing us of the issue or having recommended any preventative maintenance maza caused a very dangerous situation for my family. I have contacted Mazda usa and they have been unhelpful.

The vehicle was identified at the dealership as having a leaking transfer case that needed to be replaced. During this replacement the transmission splines were also noted to be damaged due to the faulty transfer case. Therefore both the transfer case and transmission needed to be replaced at my expense.

Any time there is even a slight incline in the road and anything that could lessen traction such as a little gravel, my tires spin and the car does not move. It's especially bad in any type of inclement weather, rain, snow, sleet. I loose all traction. The back tires do not move at all and the front tires spin. The tires have good treads.

Takata recall I had to put in my VIN to make an appointment for recalls & was sent a message back stating there are no recalls on my car. When I looked it up on your website it says my car is in recall for airbags and lower control arm. But according to the Mazda dealer & the Mazda website I don't have any recalls on my car!!! so to date I haven't been able to fix the items that are being recalled. When the recall for the airbags came out I contacted Mazda & there was no recall. Again when the recall was expanded I contacted Mazda. My vehicle was not on the list. I went to your site to see what you had about my car & discovered you have 2 open recalls on my car that as far as far as Mazda is concerned I have none. Yet you have on your website that I do so I am trying to get to the bottom of this. Does my car have any recalls or not" I also want to point out that there was a recall on the transfer case on my car. Now when I bought the car the reason why I bought it with high mileage was because the car was supposed to be certified preowned. I was given the 1 year warranty. Then I was told that the recall on the transfer case would be valid until 100000 mile. So when my transfer case needed to be repaired at 92000 miles. I contacted Mazda & after months of back & forth I was told I didn't qualify for them to take care of the repair even though it looks like a monster took a bite out of the transfer case at 92000 miles because according to their records my car was not certified preowned. Iasked to reconsider becsuse the transfer case wss completely destroyed St 92000. They said they could not make an exception with me becsuse then they'd have to make exceptions for others. I was told to get in touch with the dealer I'm getting in touch about that this week. There is something odd about all of this. How come Mazda doesn't have the recalls for my car that you have"

I was driving my 2011 Mazda Cx-9 and the car was smelling like it was burning and then it sounded like a pile of rocks being tossed around I pulled over to the side of the road and something exploded the car came to an abrupt stop and smoke came from underneath the hood. I had it towed to a repair shop and was told the transfer case went out and messed up the transmission. After doing research on the internet I found out this is a common problem that Mazda has known about for some time and has failed to notify the customer. This problem has apparently caused vehicles to catch fire while driving. After contacting Mazda they say they extended the warranty to 90,000 miles because of this problem but hasn't notified the owners of the vehicle. Mazda says it hasn't been recalled because it isn't a safety issue (which I disagree with, it could cause great harm or death) and it hasn't been reported enough. Mazda said they would replace the transfer case but not the labor or transmission. I believe this should be recalled since apparently it's happening in all Cx-9 vehicles between certain years. It's a defective part, nothing I did and I am left to pay to fix a problem that Mazda knows is their fault. My car has between 90,400 and 90,500 miles and I shouldn't be having this kind of major problem with a vehicle under 100,000 miles. If I would have been driving down an interstate at 70mph I have to wonder if I would have had an accident with injury or if my car would have caught fire what would have happened. I believe this is a major safety issue and needs to be investigated.

My power train was supposed to be covered to 100,000 miles. When the tranfer case had to be replaced as per warning it happened at 93000 onstead of 90000 but I was told that not only eas I not covered but that the supposed warranty covered to 100000 miles was not valid either because the car wasn't classified at Mazda as a certified pre-owned car and the only reason I bought the car was although the mileage was high, approximately 54,300 miles for a 2 yr.old car I purchased it because with it supposedly being pre-owned car, the power train was to be warranteed to 100000 miles so picture my shock whrn I was told that the car was not considered to be pre-owned and that the power trsin wouldn't be covered. I must take it up with the dealer. So I was stick with the payment of the replacement of a part that was listed for recall. So for 2000 miles past original recall mileage and because Mazda had no record of my car being pre-owned I had to pay for everything myself. It looked like a monster had taken a bite of the part in question. I still have part cause I 'm still trying to get my money back to no avail#!!! it was stationary when the defect became evident.

Transfer case - had unusual wear and tear on the transfer case that lead me to lose steering and driving capability when driving to work. Took my car to car dealer and the transfer case was ground down and the transmission was rusting. Had no water damage and cost over $4,000. Since have researched and found that many Mazda owners have been experiences issues with their transmission and transfer case. I believe this should be looked into.

2011 Mazda Cx-9 transfer case breakdown while moving due to fluid leaking out, causing severe wear on the transmission and disabling vehicle. My wife heard a strange sound 2 weeks ago and when she parked the car in the garage, there was a strange smell, like burnt wire or rotten egg smell. Had it evaluated at the local garage and they diagnosed leaking fluid from transfer case, which destroyed the bearings and threads around the shaft. The mechanic says this fluid is never supposed to have to be changed according to the Mazda manual. And there is so little fluid in the transfer case, it is hard to detect the leaking when it happens. I checked on google and there were hundreds of similar reports of tranfer case failure. One guy had four transfer cases installed in the first 20,000 miles after the car was purchased new. This is dangerous. If the transfer case fails at night or during a snowstorm, people could get killed. Not to mention the $3,000 to $8,000 bill for repair depending on whether it is just the transfer case or if it also the transmission that needs repair. This matter should be investigated as a recall item. Apparently, there have been several service bulletins and extensions of transfer case warranties offered by Mazda. The problem is widespread, with the edmund's complaints of failure including the years 2008-2014. It does not necessarily rleate to the amount of miles on the vehicle because many have failed shortly after being purchased new. The fact that Mazda has handled this on an individual event basis and very quietly has kept this from becoming newsworthy but the problem is so widespread, dangerous and costly, that the federal government should get involved.

I just bought an 2011 Cx-9 Mazda few weeks ago. When I was parking I noticed that every time I put the car in drive it make a sound very hard, and sometimes when putting it in reverse. It may be some problems with the transfer case. In addition, when the car is running on 2nd another weird sound. I am taking the car to the near dealer if the problem continue.

Traveling with family on I95 started smelling a burning odor. Later developed a distinct vibration and grinding sound. Got it home now non usable. Vehicle was previously repaired at my shop, a loss due to hurricane sandy, and as such branded. Faulkner Mazda and Mazda corporation both denied any warranty claim due to title branding even though both admitted it was a safety issue, although the service dept at faulkner did add "that anything could cause an accident". I am just lucky that it didn't grenade while on the interstate at speed with my family in the car. Corporate Mazda advised me to save my receipts in case they issue a recall in the future. Will not recommend Mazda to anyone in the future.

The Mazda 2011 Cx-9 crossover SUV seems to have a defect in the power transfer unit (ptu). Mazda North american operations issued a letter to Mazda owners informing about a special service program to extend the warranty coverage for the repair of the power transfer unit (ptu) on "certain 2010-2011 Cx-9 all-wheel drive vehicles produced from July 28, 2009 through December 2, 2013." I quote the letter. On March 18, 2015, I began to experience a problem whereby my 2011 Cx-9 made a grinding and snapping sound when in reverse mode. This behavior was followed by a pungent odor in the cabin. I contacted the nearest dealership and tried to get an immediate appointment to examine the vehicle. However the dealership could not accommodate me nor expressed any awareness of the symptoms. Yet, the letter was published since last year. I contacted a local mechanic and had them inspect the vehicle and they diagnosed the problem exactly as described in the letter from Mazda. In fact, the mechanic is aware of this problem with Mazda and Lincoln brand vehicles. Currently, I am having trouble getting immediate assistance from the dealership or Mazda North american operations. I called several times to the dealership and they were unresponsive. Is NHTSA aware of this ptu defect and what was necessary to require a recall/replacement of the ptu 'prior' to inevitable failure as we experienced? thank you.
