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.

Mazda Cx-9 2018
- 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.

- 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

- Summary: Hello, I have been to a Mazda dealer complaining of clicking and squeaky brakes for 2 years now. 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.

Vehicle year: 2017
Looking for a smooth and peaceful ride? Look no further! Mazda has done an excellent job in achieving a quiet ride, even on rough road surfaces. At 70mph on a bumpy highway, you can still have a normal conversation inside the vehicle. That's what really impressed me. After six months of driving, I can say that everything else is excellent too, including the impressive 28 MPG on the highway. The only minor issue I've encountered is that the adaptive cruise control safety feature can sometimes go into auto braking mode unnecessarily when it detects a hazard in the adjacent lane. Overall, this vehicle is a huge improvement over the Acura MDX it replaced.

Just purchased, so it's only been one week. So far, we're loving it! It's extremely fun to drive and a real head-turner in the neighborhood. I highly recommend giving it a try if you're in the market for a large crossover.

Vehicle year: 2019
The CX-9 is a great fit for me as the only occupant 98% of the time. It boasts a stunning design and luxurious interior, with no cheap plastic in sight. The leather is superb, and the real aluminum trim on the doors and dash, as well as the beautifully machined aluminum knobs for the infotainment system, give it a high-end feel. Despite my initial reluctance to move from a V6 to a turbo 4 cylinder, Mazda has tuned this engine to perform, and the bountiful torque means you'll never notice the difference. The chassis and suspension deliver exceptional handling and a quiet ride overall. The suite of safety features, including lane keeping assist, adaptive cruise, reactive braking, and blind spot monitoring, are engaging and actually help you drive more safely. The head's up display is outstanding, providing speed, speed limit info, safety suite feedback, and turn-by-turn directions from the nav system. The 12 speaker Bose stereo is better than any factory system I've experienced in years. However, the front cockpit is a little snug, and the front seats could have more adjustment and longer cushions for better thigh support. Third row seating is a penalty box for other than small children, but I just folded them down and expanded my cargo capacity. Interior cabin storage is also very meager. Overall, the CX-9 is a fantastic choice for those seeking a stylish and luxurious crossover.The HVAC system is a bit slow to heat/cool the interior, but it's still acceptable. The ventilated cooled seats work very well. However, the infotainment/nav system is a bit clunky to use and looks dated in appearance. Your opinion on this will depend on what your last car was. Additionally, it takes quite a while to boot up. Although the Mazda CX-9 has a 360-degree camera, the resolution is poor, which is surprising given how far miniature camera technology has advanced in recent years. The piano black trim around the shifter and door window switches is quite fragile and will scratch easily. Finally, if you're into physical media, the CX-9 does not offer a CD player. Overall, after a month of ownership, I am enjoying my new Mazda and would recommend it to anyone who needs a crossover/SUV with more room than the 2-row models, but will rarely, if ever, need to put passengers in the very back. I researched mid-sized 3-row crossovers for over a year before making this purchase and highly recommend anyone shopping for any new vehicle to spend a lot of time studying owner's forums to get the straight scoop on potential problem areas. The Mazda CX-9 Grand Touring (FWD) beat out the Toyota Highlander Limited Platinum and Honda Pilot Touring in my evaluation. One year later, I'm happy to report that my CX-9 GT has been a trouble-free pleasure to own. I've had no difficulties with this SUV and have driven a little over 7,000 miles. It rides and handles great, and the performance from the 4-cylinder turbo engine is brisk. My only annoyance is the sluggish boot-up of the infotainment system, which occasionally won't load all of the Sirius/XM stations. On mostly rural backroads and highways, I get 22-24 MPG. As I start my third year of ownership of the 2019 CX-9 GT with FWD, I'm happy to report that, despite reduced activity in 2020 due to Covid, I've only put 11,000 miles on the odometer.So far, I've had a great experience with my CX-9. It's comfortable and sporty to drive, especially for an SUV. Maintenance has been routine, with just oil/filter changes needed. The only issue I've had is with the automatic folding side mirrors. Sometimes, when the car is unlocked and the mirrors are fully deployed, they will either close completely or start to close then reopen. However, this only happens when the car is parked and the engine is off. I did some research and found out that there is a TSB about the auto-folding mirrors, which my VIN is covered under. Although the dealership couldn't reproduce the problem, they did confirm that my car is covered under the TSB. Other than that, it's been a good experience. In the past 4 years, I've driven a little over 20K miles on my 2019 CX-9 GT FWD and continue to enjoy pretty much trouble-free motoring. The electric folding mirrors continue to do strange things, but the passenger side mirror stopped folding all the way in when locking the vehicle for a few months this past winter and the dealer couldn't find a problem. Lately, it has been operating normally. Mileage remains about the same around 22-23 MPG and occasionally 24-25 on longer highway trips. One thing to note for potential pre-owned buyers is that on the Mazda 24/7 owners forum, there is an ongoing thread about issues with this generation CX-9 with the turbo 4-cyl. Some owners are having coolant leaks due to an engine defect which requires a major repair and in some cases an entire new engine. It seems earlier model years or those with higher mileage are involved, but I'm monitoring this situation closely. So, if you're considering buying a pre-owned CX-9, caveat emptor.As mentioned last time, the Mazda CX-9 turbo 4 of this generation has some well-documented engine problems that you should be aware of before making a purchase. These issues are often reported on owner's forums like Mazda 24/7, and include a coolant leak due to a cracked cylinder head or an oil leak, both of which may require a complete engine replacement that can cost thousands of pounds. While there are TSB's out on this known problem, there is no recall, and some affected owners are understandably unhappy. If you're considering buying a used 2016-2022 CX-9, I would advise you to do some research on these owner's forums to know what you're getting into. Personally, I plan to ride this out until I replace my car in early 2025, since I don't drive that much and hope the lower mileage and wear and tear will spare me this problem. 5-YEAR UPDATE: Not much else to report, at ~24K miles I continue to have no difficulties with this vehicle other than the few issues with the side mirrors I've reported on before. Once in a while, the Sirius/XM tuner fails to boot up, and I have to stop/re-start the car or go online and have Sirius/XM send the authentication code to the radio, but this is a rare occurrence. I still plan to replace it come spring 2025.

Although my 2010 CX-9 started off well, it has unfortunately experienced several issues such as blown lights, a malfunctioning A/C, a faulty water pump that caused engine damage, and now idle surging and A/C issues. As a result, I am in the market for a new car.

I brought my 2021 CX-9 Grand Touring into Mazda three weeks ago because the computer and electronic systems were not working. Unfortunately, the radio, navigation, heads up display, charging ports, and clock were all affected. Despite the issue, Mazda did not have a fix for it at the time and informed me that they were working on it. However, I did not receive any updates or calls back from them. I was disappointed, especially since I had only owned the car for nine weeks. Mazda did not offer any help or answers to make things right. UPDATE: I am happy to report that Mazda has finally found a fix for the computer system. They have updated it, and all 2021 Mazda CX-9's will require this update. They have resolved the issue, and I will update you on how the fix works after a few thousand miles.

Hi there! Just wanted to let you know that the transmission unfortunately went at 91,400 miles. The estimate for repairs is around $8,000. Let me know if you have any questions or concerns!

Hi there! The car has had one owner and has been well-maintained with regular oil changes. Unfortunately, the water pump and timing chain (Po216 code) recently failed, which can be quite expensive to repair. It's important to note that these repairs may not fully reveal the extent of the engine damage. Some ASE-certified mechanics may refuse to do the work due to concerns about the design history. In fact, there is currently a lawsuit pending regarding Ford Lincoln water pump engine failures (https://www.ktmc.com/ford-lincoln-water-pump-engine-failure).

Our CX-9 experienced an issue where it burned a quart of oil between oil changes, which unfortunately led to misfiring and violent shaking while driving. Despite there being a service bulletin, the dealer did not acknowledge the problem or offer a solution. As a result, we had to trade it out. It's important to be aware of this issue with Mazda vehicles.
