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 is wrong
- Mazda North American Operations (Mazda) is recalling certain model year 2007-2014 CX-9 vehicles manufactured October 24, 2006, to December 28, 2013. The affected vehicles have front suspension ball joints that may corrode from water leaking into the fitting.
- Risk
- Over time, the ball joint corrosion may result in the front lower control arm separating from the ball joint, causing a loss of steering control and increasing the risk of a crash.
- Remedy
- Mazda will notify owners, and dealers will replace both the left and right lower control arms, free of charge. The recall began on September 14, 2015. The recall will begin with model year 2007-2009 vehicles registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, Washington D.C., West Virginia, and Wisconsin. The second phase will be for model year 2010-2014 vehicles in the same states. Finally, all remaining vehicles will be remedied. Owners may contact Mazda customer service at 1‑800‑222‑5500.

Lower ball joint separation
In an July 7,2015 letter to the federal safety agency, Mazda identified a safety defect that could result in lower ball joint separation in approximately 193,484 model year (MY) 2007 through 2014 Mazda CX-9 vehicles (the federal safety agency Recall No. 15V‑451,Mazda 8515G).Mazda indicated that damage to the ball joint boot may allow water to enter the front suspension ball joint fitting during use which may result in premature ball joint wear and a progressively looser joint.In January 2014, Mazda implemented redesigned lower control arms in production vehicles to improve the durability of the lower ball joints.The redesign involved changing the shape of the top surface of the ball joint boot cover and adding a suspension plate to the undersurface of the knuckle.Mazda's recall will replace the defect lower control arms with the redesigned parts.ODI's analysis of information collected during PE15-022 identified a total of 62 ball joint separation incidents, including 34 identified in ODI complaints and 31 identified in Mazda complaints and field reports (3 of the Mazda records involve vehicles/incidents that were also reported to ODI).When Mazda's design change was implemented, most of the field experience related to lower ball joints involved complaints of noise and premature wear-out.Only 1 of the ODI and 6 of the additional Mazda separation complaints identified in ODI's analysis were reported prior to January 2014.Significant increases in the number and trend in separation complaints were observed in 2015, when 30 of the ODI complaints and 16 of the additional Mazda complaints were reported.The report trend appears to be accelerating, with 29 of the reports received after ODI opened PE15-022 on June 9, 2015.There has been one crash reported to ODI related to the alleged defect (VOQ 10746510). This investigation is closed based on Mazda's recall.The 34 VOQs associated with this investigation are: 10747358, 10746510, 10744897, 10743509, 10736229, 10735938, 10734763, 10734302, 10734290, 10733813, 10732578, 10732217, 10732154, 10731850, 10730736, 10730280, 10730143, 10730114, 10726622, 10726480 10726448, 10726168, 10725839, 10725567, 10725488, 10725427, 10725390, 10717510, 10714469, 10695142, 10668978, 10648429, 10640541, 10546535

The local dealer was contacted, and it was confirmed that the part was not available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.

Additionally, the front end of the vehicle was unstable. The vehicle was taken to the local dealer who indicated that the failure was due to the recall however, the part was on backorder.

There are noises coming from the front tires, when driving. No one could pinpoint the problem. Brake booster went out a couple months later.
Vehicle pulsates while braking while driving fast or at slower speeds. The steering wheel does not shake. The brake pedal does not pulsate. The vehicle brakes were changed several times with new rotors and pads on all four tires. I noticed there was a recall on lower control arms #15v‑451. It only was inspected at the time of recall but never changed. Could it be possible that they are now worn and can be changed per the recall.
Control arm/ball joints- had to have replaced again on 9/21/18 after both being replaced on 1/12/2016 as part of a recall. Feels like the car is trying to steer itself and not very safe to drive. And then have to pay for another alignment which I just had done as well. There should be some type of warranty on a recall repair.
We took our 2010 cx-9 with 99,000 miles the mazda dealer in union nj because of a noise in the car and were told that the rear subframe has rotted out and is destroying the rear diff mounting bolts. We were also told the exhaust system is also rotted out and the vehicle is unsafe to drive. If we go over a pot hole, the whole undercarriage of car can fall out. This car was not kept at the beach and well maintained.
Took my car to dealer 2-3 times for the brakes, way before my warranty was any where near expiring, because I kept hearing a grinding sound. They kept telling me nothing was wrong, that my brakes had some gravel on them and they just cleaned them. I don't travel on dirt roads or anything, city roads/highways. No out of town travel at all, actual only in town travel, home/work. My 2nd concern is, while driving sometimes my speed seems to shift, as if the gears are shifting. 3rd concern is, I received a recall notice, don't recall what it was about but I took it to the dealership and I was told they done that work last time I came in but I don't believe it was done, since they haven't been honest with me before. They didn't even look at the letter. If I recall correctly brake complaints/ service started 2011 or 2012 to 2014....
