Mazda Cx-9 problems
The Mazda CX-9 is a mid-size crossover SUV manufactured by Mazda in Japan since 2006 through two generations With three-row seating, it was Mazda's largest passenger vehicle until the arrival of the CX-90.
Despite being built in Japan at Mazda's Ujina #1 plant in Hiroshima Prefecture, the CX-9 was never offered in the Japanese domestic market. The shorter and narrower Mazda CX-8 was offered in Japan instead.
First generation (TB; 2006)
The first generation CX-9 was originally fitted with a 3.5 L Ford V6 engine, but, in 2008, the engine was changed to a 3.7 L unit producing 204 kW (274 hp) and 366 N⋅m (270 lb⋅ft) of torque. The updated engine was introduced in June 2007 and it was now built by Mazda themselves. This engine was coupled with a six speed automatic transmission. The first generation is based on the Ford CD3 platform that is shared with many Ford and Mazda models; the Ford Edge is its close mechanical sibling. It was launched at the 2006 New York International Auto Show.
Standard safety equipment included blind spot monitoring, backup camera, electronic stability control, traction control, roll stability control, front side impact airbags, and three row side curtain airbags.

- Date Of Incident: 2024-10-21
- Date Complaint: 2024-10-27
- VIN: JM3TCBEY4J0
- Components: ENGINE
- Summary: My vehicle was low on antifreeze. I brought it into the dealer and had them look at it. They told me there was an antifreeze leak inside the engine. I told them, I think there's a service bulletin on it. TSB-01-013-21 And there are updates to it. They told me that the antifreeze leak does not pertain to this service bulletin. I told them, how can that be? When it's an antifreeze leak with an engine that only has 66000 miles on it so far. I spoke to mazda customer service in California They said the dealer is trying to get some financial relief for me to replace a $10000 engine. Which they said is on back order till march 2025. I said how can this leak not be a problem when the engine is on back order, I feel that this should not have happened With a engine, that has 66000 miles on it? And it should be fixed free of charge because antifreeze leak is a known problem with these engines since 2016, and they never notified me to bring it in and have the defective part fixed Which causes the antifreeze leak. If they did that, my engine would not have blown and would not need replacement. I'm hoping they understand and do the right thing and fix this.

Mazda Cx-9 2018
- Date Of Incident: 2024-07-18
- Date Complaint: 2024-10-20
- VIN: JM3TCABY1J0
- Components: ENGINE
- Summary: I purchased a 2018 Mazda cx9 from a local used car dealer several weeks ago. Check engine light came on after a few weeks for cylinder 3 misfire and there was a steep decline of the vehicle performance (hard start, rough idle, lower mpg, sluggish driving). Took it to Berge Mazda who charged me for diagnostics/spark plugs, and ignition coil. They informed me the next steps were a compression tests, fuel injectors and if that didn’t fix the problem then they wanted to strip down the engine to evaluate the cylinder head. At this point I decided to take it to my local mechanic who I trust, he diagnosed a cracked cylinder head. Now I’m stuck with a car I just bought that’s unsafe to drive needing a 6-8k repair. Upon further research there is a widespread problem with Mazda’s manufacturing of there cylinder heads on certain models (including the 2018 Mazda cx9). This is confirmed by TSB’s from Mazda along with a class action lawsuit recently filed. Upon more research on my vehicles history, I gathered that my vehicle was traded into Horne Mazda and then a couple days later auctioned to the used car dealer I bought it from. The fact that Mazda is selling off their own defective vehicles that are unsafe at auctions is absolutely disgusting and something needs to be done about it.

Mazda Cx-9 2019
- Date Of Incident: 2024-08-14
- Date Complaint: 2024-10-16
- VIN: JM3TCBDY3K0
- Components: POWER TRAIN
- Summary: 2019 CX-9 GT, 30K miles, in August found coolant leaking under the car. This was 5 months past the warranty (but only 30K miles!). After doing research online, I found this is a massively common issue with all engines from several years encompassing 2019, where the coolant leaks due to a cracked cylinder head. There is a TSB from Mazda, which requires replacement of the engine, once the crack is developed. I immediately called Mazda corporate on 8/15/2024 and opened the case with them. They said they can try to assist, but first I have to take the car to the dealer for diagnosis of the problem. Had to wait 2 weeks, then leave the car, they did a full inspection and confirmed cracked cylinder head. Dealer opened up claim with Mazda (which apparently is separate from the case I made when I called the corporate). I had to go back because Mazda warranty dept. was asking the dealer to prove the engine was overheating, which it hasn't yet, because I kept adding coolant, so the engine never overheated. But the dealer lowered the coolant and had the engine overheat a little bit just to generate the computer code the warranty dept was requiring. This itself was an unnecessary additional potentially damaging scenario, completely unnecessary when the crack in the cylinder head was already found, and the coolant leak is clearly present. After all this, Mazda lowered their original quote from $10K to $6K and expect me to pay this to replace the engine. I called the corporate (customer relations) many times, but they said if the warranty dept. decided this, they cannot change it. And there's no way to talk to warranty dept. directly (not customer facing). We purchased a brand new factory assembled car for well over $40K. Due to a very common, Mazda acknowledged, engine manufacturing defect, the major component of the vehicle, its engine, requires replacement at only 30K miles! This is NOT a reasonable expectancy when purchasing any vehicle.

- Date Complaint: 2024-10-15

Dealer replaced both front and back breaks and rotors around 22k year ago and to my surprise the issues persist, currently vehicle is at 49k. There is a TSB( 04-001/22) out for my vin and year, so they know its a manufacturing defect and all they do is throw white break grease and a month later the noise is there again when breaking , backing up. I am not the only one, people of reddit confirm this and so does a general google search. Besides that i love the car and the dealer was super cool about it all but I'm sorry, this is unacceptable, Every time i go get an oil change i ask about a fix and nothing.

Congratulations on your new car! It's great to hear that you found a stylish and affordable option that suits your needs. The Mazda CX-9 seems to have impressed you with its handling, powerful engine, and beautiful interior. It's also great to hear that the second row seating is adjustable for extra comfort. The Grand Touring model sounds like it has all the technology features you could want, including a heads-up display. While the infotainment system could use some improvement, it's good to know that the car has everything else you need. Thanks for sharing your thoughts on the CX-9!

First thing to go on this car? The paint job! Unfortunately, rust developed in two spots that could have been prevented. Additionally, the bumper had to be replaced due to cosmetic problems. However, despite only receiving routine maintenance over the past 9 years and 125,000 miles, this vehicle has proven to be incredibly reliable. My favorite features include the subwoofer, remote start, keyless ignition, heated leather seats, acceleration, and handling. It also has just the right amount of space for our young family of 6.

After driving this car for a month, I've learned a lot about it. Firstly, I absolutely love the car and I'm confident that I made the right choice. The ride is much smoother than the pilot or highlander, which we test drove. The interior finishes are comparable to those of Lexus, Acura, and other high-end brands. However, there are a few things you should be aware of. The rear lift gate doesn't go all the way up, which could be an issue for taller people like myself. The navigation and entertainment system are poorly designed, making it difficult to scroll through stations while driving. Additionally, you can't enter any address while driving, which could be inconvenient for both the driver and passenger. Unfortunately, there's no Android or Apple Play system. Lastly, the front seats are quite narrow, which may not be comfortable for bigger people or those who prefer more space. On the bright side, the cargo space is ample. If you need more cargo space, I recommend the Honda Pilot, but the CX-9 works perfectly for our family.

I've been looking to upgrade from my trusty, but tired Scion xD. I loved that little car, but it was getting a bit old and the line was terminated by Toyota. I looked at SUVs from Nissan, Toyota, Honda, Kia, and even Audi, but none of them had the same appeal as the CX-9. I purchased the Signature in Soul Red and elected to go with the Parchment Napa leather, which makes for a great color combination inside and out. The ride is outstanding, and the performance and handling are great. As many have mentioned before, the Infotainment system could be better, but for me, it does what I need it to and I have no complaints about it. Regarding the third row space for passengers, I don't use it, so it matters little to me. As long as fuel prices stay relatively affordable, I will continue to feed it higher octane gas for better performance, which is really nice for the little
Are you having problems with your Mazda Cx-9?

This car is a great option for those who want a 3rd row and 4-wheel drive without having to go for a minivan. While we did experience some issues after the first 20k miles, we made sure to change the oil and follow all recommended dealer services. Unfortunately, we did encounter some problems such as rust on the back hatch door, window and body liners falling off, and the rear wheel bearings and strut needing replacement. However, we believe that these issues can be resolved and we still recommend this car. We advise against purchasing any additional warranties as they are not supported by the dealer.

Car is OK, fun to drive. However, it gets worse gas mileage than expected, around 19 mpg instead of the 26 mpg that Mazda claims. Additionally, I've experienced some issues with the electrical system.

I purchased this MAZDA used in 2008, one year after it was manufactured. Unfortunately, I have had some issues with its performance and it has been quite expensive to maintain due to the high cost of repairs. While I have owned other Japanese cars without any problems, my experience with this MAZDA has been disappointing. However, I am determined to make it last for at least another 3 years. Although I may not purchase another MAZDA in the future, I appreciate the other cars I have owned and enjoyed keeping them for at least 10 years.

The CX-9 initially appeared to be a great car, with plenty of room and decent comfort. However, the fuel economy is lower than expected for a car of this size, averaging only 14-16 mpg in-town and 18 mpg on the highway. Unfortunately, the Transfer Case is a major issue that led to a negative review. The transfer case failed at only 12,500 miles, causing toxic oil fumes to fill the car through the venting system. This made my wife and daughter sick and caused respiratory issues throughout the evening and night. I found out that this is a known issue with the CX-9, and the technician informed me that they have new T-Cases on hand due to how many they replace. The Blue Tooth system also takes up to five minutes to connect, which is a minor inconvenience. Despite these issues, customer service was very accepting of responsibility and attempted to address the issue.
Reinhold Skiles 2025-04-26

There were many things I loved about the CX9, but unfortunately, it turned into a lemon. At mile 4000, I heard something fall off the car and it has been rattling ever since. The rattling was mixed in with excessive road noise, and later the two noises were joined by squeaking and creaking like an old wooden ship on the high seas. I took the CX9 to Mazda service in Vallejo at least 10 times for this issue, and they tried to repair it about 3-5 times, but with no luck. They replaced the control arm twice and the struts twice, but it's still rattling as loud as ever.
