2020 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.

ENGINE PROBLEM
- Date Of Incident: 2023-07-01
- VIN: JM3TCBCY0L0
- Components: ENGINE
- Summary: Some vehicles may have coolant leaks at the cylinder head around the exhaust manifold. There may be cracks at the stud bolt hole or at the outside of the exhaust manifold - from Mazda's TSB. Excessive coolant leak leading to engine-overheating and going into 'limp mode' couldn't drive faster than around 30 mph. Mazda has repeatedly declined help with goodwill requests and any further assistance. ref. https: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
ELECTRICAL SYSTEM,UNKNOWN OR OTHER PROBLEM
- Date Of Incident: 2023-05-14
- VIN: JM3TCBDY8L0
- Components: ELECTRICAL SYSTEM,UNKNOWN OR OTHER
- Summary: We were on the freeway and all of a sudden it stopped accelerating and the engine light, sensor light, and sensor warning came on. We could not accelerate, that became disabled and we had to pull over. My husband said our fluid levels were normal and he checked them all in the shoulder of the freeway. We turned the vehicle off then on again and all lights went away and we continued on. This is a safety hazard because the car would not accelerate while we were going 60 mph on the freeway. I quickly took a picture of the dash as this was happening so I can take it to the dealer.
VISIBILITY/WIPER PROBLEM
- Date Of Incident: 2022-07-09
- VIN: jm3tcbdy5l0
- Components: VISIBILITY/WIPER
- Summary: While driving at freeway speed in Oregon, with 85 degrees ambient temperature and A/C inside set to 74 degrees, our CX-9 sunroof exploded outward. The sound was close to a very loud pop, and not the sound of rock/debris impact. At the time of explosion, there were no vehicles nearby and no overpasses from which an object could have dropped. The vehicle had been washed the day before and there was no visible damage to the sunroof. At the time of explosion, the sunroof and interior cover were closed. Upon stopping the vehicle (within less than one mile) inspection showed that nearly no glass fell downward, and approximately 50% of the total sunroof area had blown upward and out of the vehicle. The remainder of the shattered glass was still contained within the frame, with the edges visibly curved upward as though the glass had been pulled away from the car. There were three people in the vehicle at the time (driver, front seat passenger, and middle row passenger behind the driver). The two passengers were asleep and woke abruptly thinking we had been hit by something, as the explosive bang was followed by the sound of air rushing past the hole. There was no sound of glass rattling in the area over the sunroof cover, which seems to indicate glass had not broken inward and then blew out before stopping. I (driver) kept the cover closed and promptly pulled off the freeway to assess damage. I was unable to visit a dealer for warranty assessment due to vacation travel. A phone call to my local dealer did indicate it should be covered under warranty but it has not been inspected, this has not yet been confirmed. I rarely open the sunroof cover and have only opened the sunroof itself 3-4 times since purchase two years prior (2020). I did open the sunroof to give my son fresh air on curvy roads approximately one hour prior. No injuries, but if the cover had been opened we may have had glass falling into the cabin. No other visible or audible warnings occurred.
STRUCTURE PROBLEM
- Date Of Incident: 2022-03-22
- VIN: Jm3tcady4l0
- Components: STRUCTURE
- Summary: The passenger rear plastic wheel trim fell off with no incident/ damage
FORWARD COLLISION AVOIDANCE PROBLEM
- Date Of Incident: 2021-09-12
- VIN: Jm3tcbcy4l0
- Components: FORWARD COLLISION AVOIDANCE
- Summary: On 10/12/2021 we were driving on and urban street when the vehicle infront of us signaled and initiated a right hand turn. At that point were we traveling approximately 20 mph, and we were driving with active cruise disengaged. When we were around 150 feet behind the vehicle taking a right when our CX-9 falsely engaged the emergency braking. Our car with our whole family in it locked up the brakes and stopped in 80 feet short of the car taking a right. The vehicle behind us only managed to stop 10 feet short of hitting us in the rear. It is in the 4 people in our vehicles opinion that this operation was both terrifying and dangerous to use and those following.
ELECTRICAL SYSTEM PROBLEM
- Date Of Incident: 2021-07-27
- VIN: JM3TCBEYXL0
- Components: ELECTRICAL SYSTEM
- Summary: The 2020 Mazda completely shut off following an exit from an expressway, turn under a bridge and slow down for a red light. The Mazda electrically shut off and coasted to a braked stop in the center lane of a 3 lane road. The entire electrical system went dead, no exterior lights, signals, instrument panel or radio. There was no warning, everything electrical just shut off. In a moving traffic situation the car could not maneuver or restart without being placed in PARK. (There is a history of Mazda CX 9's having a similar problem which sent the driver to the local dealership.) The car was restarted by shifting into Park and pressing the start button, all functions appeared normal as the driver moved it to a parking lot to review the situation. The driver was unable to re-create the complete shut down and finished the trip. The driver took the Mazda to the dealer following the incident and was asked to leave the Mazda for observation. The driver was notified by the dealership that the problem was being elevated to the national team for diagnosis. 10 days later the local dealer called the driver and said that they; nor the Mazda engineers in California; could reproduce the system shutting off or find any error codes. They wanted to return the car to the driver with no need for a repair. The driver spoke to the National Mazda help line and the representative was aware of the situation. The representative reiterated that engineers had been unable to find the source for the incident in the computer logs so they could not provide a remedy. The representative offered the driver the choose of a purchase buy back and a discount on the purchase of a new car.
POWER TRAIN PROBLEM
- Date Of Incident: 2021-01-15
- VIN: JM3TCBDY1L0
- Components: POWER TRAIN
- Summary: FUEL CAP LIGHT ON IN DEC 2020. OUR CAR MILEAGE ~14,000 MILES . WE BOUGHT BRAND NEW CX9 2020 IN AUGUST. DEALER INSPECTED IT AND FOUND NOTHING WRONG. DEALER REPROGRAMMED IT. A MONTH LATER JAN 1,2021, FUEL CAP LIGHT IS ON ON AGAIN. WE IGNORED IT THINKING IT IS ANOTHER PROGRAM ISSUE. CAR STARTED TO JERK AND VIBRATE AT STOP SIGN. WE BROUGHT TO DEALER THE NEXT DAY. DEALER SAID CHARCOAL BOX IS LEAKING. I THOUGHT CHARCOAL BOX SHOULD LAST A LIFE TIME. THEY SAID IT IS NOT UNDER WARRANTY: $680 LATER, THE JERKING/VIBRATING ISSUE IS FIXED. HOPEFULLY THAT IS IT SINCE WE ONLY HAVE THE CAR FOR 5 MONTHS
ENGINE PROBLEM
- Date Of Incident: 2020-01-30
- VIN: JM3TCBDY5L0
- Components: ENGINE
- Summary: THE MAZDA CX-9 UNCOMMANDED ENGINE ACCELERATION REPORTED HEREIN DID NOT RESULT IN ANY DAMAGE PRIMARILY BECAUSE IT COMMENCED SEVERAL SECONDS AFTER I BEGAN LIGHT BRAKING WHILE APPROACHING A RED TRAFFIC LIGHT. MY IMMEDIATE RESPONSE WAS TO INCREASE BRAKE PRESSURE; THERE WAS NO NEED FOR ME TO MOVE MY LEG OTHER THAN PRESSING HARDER WITH MY FOOT. MY FOOT HAD BEEN OFF THE ACCELERATOR FOR MANY SECONDS WHILE ALLOWING THE CAR TO SLOWLY DECELERATE WHILE COASTING TOWARD TRAFFIC STOPPED AT A RED LIGHT. WITHIN TWO SECONDS OF COMMENCEMENT OF UNCOMMANDED ENGINE ACCELERATION AND WITH THE CAR FULLY STOPPED, I SHIFTED THE TRANSMISSION INTO NEUTRAL. THE ENGINE IMMEDIATELY GENERATED THE NOISE OF VERY HIGH RPM. ALTHOUGH THE DASHBOARD INCLUDES A TACHOMETER, I DID NOT IMMEDIATELY THINK TO LOOK AT IT; INSTEAD, I TURNED THE IGNITION OFF. A FEW SECONDS LATER, I SHIFTED THE TRANSMISSION INTO PARK AND RESTARTED THE CAR WHICH OPERATED NORMALLY THEREAFTER. MY FOOT DID NOT MOVE OFF THE BRAKE PEDAL DURING ANY OF THE PRECEDING SEQUENCE. ONLY THE NHTSA AND POSSIBLY THE MANUFACTURER WOULD KNOW IF THIS IS A ONE IN A BILLION-HOURS OR A MORE COMMON OCCURRENCE. I AM WILLING TO ANSWER ANY QUESTIONS THE NHTSA OR THE MANUFACTURER MIGHT HAVE. I GRADUATED FROM MIT, WORKED OVER 29 YEARS FOR THE LEADING USA COMMERCIAL AIRCRAFT MANUFACTURER AND AM CURRENTLY RETIRED.

I haven't come across the perfect car yet, as every one of them has minor annoyances. Sometimes I wonder if cars are being designed by real people for real people. Having said that, the CX-9 is mostly fine, especially for the price. I wasn't able to find a better combination. The power is good from the 4Cyl, and all safety features work as advertised. It's reasonably quiet and comfortable, especially when comparing it to my other ride, the 2019 BMW X5. The space is good for us. However, there are a few things that keep it from being a 5-star car for me. Firstly, the driver memory buttons don't adjust the mirrors, which is a huge annoyance when switching drivers all the time. Secondly, disabling the touch screen while driving is an idiotic feature that takes my eyes off the road way too often. Thirdly, the 6-speed transmission is fine for driving around town but lacks on the highway, with RPMs being way too high at 75-80, making for more noise and killing fuel economy. Fourthly, the tow hitch electric connector is buried so far back that it requires taking half the car apart to get to it. Lastly, the electronics/entertainment system feels like it's from the past decade. Overall, these are relatively minor gripes, but they keep this car from being great. After half a year, my original impressions of the car remain unchanged. It's a very decent daily driver/family hauler with minor things keeping it from being totally awesome. After a year, there haven't been any changes really, but the reliability is solid so far.

It sounds like you're really enjoying your luxury vehicle! It's great to hear that you're impressed with all the modern technology and safety features. The body style and interior seem to be a real hit too!

This is my second Mazda. I had a Mazda 3 before, but this time my wife and I needed more room for the kids, so we decided to go big. We never realized how fun and sporty it would be! We got the Touring and with the Apple CarPlay, it really makes a big difference. It’s great for the family - the kids love it and my wife is happy. I would really recommend it to anyone looking for a larger SUV with great handling, a fun drive, and plenty of room. Thank you, Mazda!

Best car you ever had! It's great to hear that you're enjoying your 2016 Grand Touring. If you're considering an upgrade, I would definitely recommend the Grand Touring or Signature models. The standard equipment on those models is truly wonderful. While the adaptive headlights and heads up display are not available on cheaper models, they are definitely worth the investment.

Congratulations on your new Mazda! It's great to hear that you found the perfect car for your needs. I appreciate your detailed review of the CX-9 Grand Touring, it's very helpful. It sounds like you had a comfortable and enjoyable ride, with plenty of power and great handling. I'm glad to hear that the safety features were not intrusive and that the headlights were bright and helpful. It's also good to know that the car can use regular or premium fuel. Thank you for sharing your experience and insights with us!The fact that it isn't just premium is a big plus. I'm going to check if the backup camera has a couple of settings. I thought the view could be a little better, but overall, it was a great start to owning this car. Mazda has made a well thought out vehicle.

The vehicle is a great value. If you're planning to lease, make sure to review Section 26 of the Mazda Financial lease agreement carefully. It states that taking the vehicle to Canada without prior written permission is prohibited. Additionally, it's important to note that only the name lessee(s) are allowed to operate the vehicle.

I loved everything about this car and was all set to buy one after a successful test drive. However, upon further consideration, I realized that the knee obstruction from the center console and the narrow seat back would be uncomfortable for me during long drives. It's disappointing because I had really fallen in love with the car.
Kenyon Runolfsson 2024-04-07
This is by far the best styled SUV. The lines, interior, sporty feel and handling are very nice. Plus, it has the room needed for family trips. However, the quiet ride does not distract me from the fact that the seats need more cushion and comfort for the long haul. Mazda is known for its sporty drive, and this CX9 doesn’t disappoint. But when it comes to dipping into luxury, I expect way more comfort. Its competitors have way more comfortable seats that are a must for long drives. My shoulders and back hurt after every long trip. The headrests do not adjust, so you’re left with not much flexibility in positioning for comfort. And it should have a bigger armrest between the front seats. I purchased this CX9 Touring in 2017 with 300 miles. The only maintenance so far has been oil changes and brakes. The infotainment screen cracked (a known issue by Mazda) but after fussing, they replaced it at no charge. I’m ready to get out of it for something more comfy for long trips. The problem is finding something with its style, class, sporty feel, and fun drive. I’m sure I can find something way more comfortable, but I must admit the style is second to none.
