Front suspension broke while my husband was driving back from a fire as he is a volunteer firefighter. He states car did not have any lights on dash to report there was a problem. The next thing he knew he heard a loud squealing noise and lost control of the vehicle taking him off road in a small ditch. As the axle broke it went upward and hit both belts and shredded them. He was not able to move or drive the car at all. I am the owner of this vehicle had I been driving I would have totaled and crashed,also I do have A [XXX] son I drive to school most days. Thank goodness my husband is a heck of a driver. I have contacted the Mazda manufacturer and they are stating that the vehicle was already fixed that they will not do a safety remedy. As I found out there was a 8515G recall for the front suspension interior corroding. I just purchased this vehicle on 2/24/2026 it broke on 3/19/2026. The vehicle states to have been fixed in 2017. I have the inspection papers from the previous dealer from whom I bought it from in 2021 and the one from the dealer that I purchased it and that inspection was in 2025. There has been no inspections after I purchased or after the catastrophic failure happened I am in process of this and my insurance is the next I'm contacting. There was no police report as there was only damage done to the vehicle,luckily no one else was involved and my husband was ok. We have never dealt with this before and didn't really know what to do or how to go about this. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What owners say
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.
Within 6-8 months of purchasing the car we noticed the brakes squeaking and vibrating. At that time the car was under 25,000 miles. At our maintenance check it was advised that we have the brakes resurfaced at the next appt. Back brakes were done in 3/2019 and the front were done in 6/2019. We noticed the squealing and vibration returned again. At our recent maintenance check, we asked to have the brakes and rotors inspected. We were told everything looked fine and nothing needed to be done, however we are still experiencing the vibration which is very troubling. We called another place explaining the issue and they said that it sounds like we need new rotors. Our car has mostly been sitting over the last year and a half with very few added miles. We're curious to know why a car with less than 25,000 miles on it needed the rotors resurfaced and why with less than 60,000 miles it needs new rotors. The brakes on the Mazda SUV's seem to wear rather quickly or perhaps the incorrect brakes are put on for this size of vehicle. The increased vibration seems like a safety hazard

》takara recall ----- the federal safety agency campaign number: 15v451000《 my car started with a scratching or grinding noise that I thought was the brakes but I just recently changed so I kept driving. When it would rain it would make noises I cant remember what exactly it was I think it was like popping. Only when it rained and I was turning. Well it turned into when I was driving anytime it was popping and cracking and then it turned into some crazy noise that almost sounded like something was falling out the bottom of my car and I was dragging on the ground but I wasnt dragging anything. I think it got water inside the ball joint and rusted. The federal safety agency campaign number: 15v451000
The transfer case was replaced at 34,000 miles and now we are having to replace the transfer case again. Additional transmission damage may have occurred. Mazda refuses to stand behind their product and admit to a design flaw. The first transfer case smelled like propane. The second transfer case had gear grinding noise
When making left turn started hearing a squeal and air conditioner shut off then floor board on front passenger side started filling with water after looking online, apparently many people have had this issue with their mazda cx9. It is caused by the drain to your air conditioner getting clogged multiple videos are online of how to unclog it this should be a clue to mazda that there is a design flaw took it to dealer and was told it was a maintenance issue no where in my maintenance manual does it say to get air conditioner drain cleaned cost 138 for them to clean it out and caused some damage to blower motor called mazda and of coarse got the run around online people are saying they have had to take theirs in multiple times to get unclogged. Some having to pay 300 each time this issue needs to be investigated and fixed
I was driving my car when the transfer case on my 2010 cx9 broke at 109.000 miles and spline gear is worn out. Overwhelming oil smell coming back into car along with horrible grinding noise. Took to my mazda dealer, mazda wasn't sure if they could fix, suggested replacing transmission. Mazda tried to fix the transfer case issue, but could have humming noise. Instead of humming noise, after one day of receiving my car back, transmission is failing. Already put $2200 into this repair, but was told the transmission could fail at any time. I find this hard to believe after I put my car in for scheduled maintenance all the time and take great care of my car.
The mazda cx9 that we purchased has a acceleration problem when we go to stop.. Mazda has never been able to solve the problem completely.. We have had 2 brake boosters replaced under warranty. We feel the car is unsafe to drive and mazda has not addressed the problem. They tell us nothing is wrong with the car. It know also has transmission problems with squeaking and grinding noises coming from the car. This is a design flaw that has not been addressed.
