• AIR BAGS

  The contact owned a 2020 Mazda CX-9. The contact stated that while driving approximately 60 MPH, a second vehicle crashed head-on into the front of the vehicle. During the head-on crash, no air bags inside the vehicle deployed. The contact sustained a concussion and right eye injury and later received medical attention. A Police report was filed at the scene. The vehicle was destroyed and towed to a local storage facility. No information was available concerning the second vehicle's occupants. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The local dealer was not contacted. The failure mileage was 130,000.

• FUEL/PROPULSION SYSTEM

  The mazda Cx-9 is having the same fuel pump issues that was recalled up until 2018 models. The issue with the lean codes and faulty fuel pump continues

• FUEL/PROPULSION SYSTEM

  Prior to [XXX] The vehicle ran rough and sputter excessively. I took car to local repair shop. Diagnostic equipment determined the fuel injector needed to be replaced. Vehicle ran better but continued to sputter and ride rough on occasion. Prior to [XXX], the vehicle stopped operating properly. The vehicle would not travel faster than 20 mph and sometimes would stop completely in the middle of the road. This was a hazardous situation. The vehicle seemed to be starved for fuel. All warning lights were displayed on the short trip home. Being too dangerous to drive the vehicle was towed to a different repair shop. Diagnostic equipment determined the throttle body needed to be replaced. This was done prior to [XXX]. I drove the car less than 5 miles after the 2nd repair and the same behavior returned. Vehicle would sputter run rough sometimes stop etc. All warning lights were displayed. Vehicle seemed to be starved for fuel. Vehicle was towed back to the repair shop. Next step will be to contact Mazda dealership in Huntsville AL and see if they will accept the Vehicle for repairs after I have it towed.

• BACK OVER PREVENTION

  Warning signal front camera sensor system malfunction Forward Smart City Brake Support malfunction When this initial happen the steering wheel becomes hard to maneuver than releases The front and back cameras are clear from any debris or obstructions What should I do next?

• TIRES

  All 4 of my BH255/50R20 XL 109v NOKIAN WR G4 vehicle tires are exhibiting abnormal tread degradation and excessive sidewall cracking. The tire defect includes a circumferential crack along the top of all 4 tires, where the top of the tire's sidewall and tread base meet. Upon tire inspection, the structural integrity and safety of these tires with continued usage is questionable. The tires in question are only 26 months old and have approximately 31K miles of usage.

• ELECTRICAL SYSTEM,UNKNOWN OR OTHER

  The information screen is getting 'spider cracks" spreading across the face and turning opaque making the information unreadable. Mazda is apparently aware of this defect and issued a TSB for earlier models. Dealers were unhelpful and quoted $1000 - $3000 to repair depending on the VIN.

• UNKNOWN OR OTHER,ENGINE,FUEL/PROPULSION SYSTEM

  The vehicle will hesitate/stall while driving down the road. The vehicle has done this multiple times and has actually shut off on 2 different occasions while at a stop. on 2 occasions now the vehicle has not wanted to start. I have taken vehicle to Mazda dealership and they can never duplicate it. When they check for any codes, the vehicle computer does not give accurate times when happened. This last date I took it to them 6/9/25, the computer said it happened 4000 miles ago. The time before, I took it in the morning it happened, 5 min after it happened and the computer said it happened 10 starts ago. The last time, 6/9/25 they said they suspect fuel pump going bad, but until the vehicle gives a "check engine" light or dies all together they are not 100% sure. The vehicle is unsafe if it dies in the middle of the freeway/road with no warning to myself or the other vehicles around me. This has been going on for at least 1 year now, maybe longer Dealership has all records. Seeing how the 2018 & 2019 Mazda CX-9 had fuel pump recalls makes me wonder if the 2020 should have been included in this recall. This has been an on going problem.6/7/25 was most recent incident.

• ELECTRICAL SYSTEM,SERVICE BRAKES,FORWARD COLLISION AVOIDANCE

  Vehicle randomly displays "smart brake system malfunction," "forward smart city brake malfunction" and " front radar system malfunction." This has been going on for at least a year. I will be driving on a highway, trying to accelerate and these messages will pop up. I'm not able to accelerate when these messages pop up and I have to turn on my hazard lights and pull over to the side of the road. The only thing that clears these warnings are for me to completely shut down my car and restart it. Luckily I have been able to get over to the side of the road on the highway without an accident, but these warning lights pop up when it's sunny out and there is no reason for the car to act the way it does. I took my car to the dealer the first time it happened and paid several hundred dollars for them to tell me that they don't know why it happened. There are several forums posted online with people having the same issues. Online posts say to make sure the sensors are clean and that the malfunction can activate if it's too hot, rainy, snowing or foggy? In my experience, it has happened only when it has been sunny. When the system decides to malfunction, the car will not accelerate, and it could make it easier for the car to be hit by another car. It's like the car just shuts down.

• SERVICE BRAKES

  I've had it repaired for over 30+ times. I'm tired of the car not being fixed. The last visit I was told maybe its the way I drive.

• POWER TRAIN,ENGINE

  The vehicle was overheating and a message came up that power will be reduced. Then it would go away and come up every 3 minutes while driving. I brought it to the service center, we filled it up with coolant and the issue kept coming back this time with a lot of white smoke coming out at vehicle start up. My mechanic said this is a bigger issue most likely to do with a coolant leak at the cylinder head. There is a technical service bulletin but no recall as of yet.

• ENGINE

  Excessive oil consumption. In less than 3000 miles, I have to add a quart of oil

• ENGINE

  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

  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

  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

  The passenger rear plastic wheel trim fell off with no incident/ damage
