Defect investigations
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

October 2021 purchase 2 Cooper Evolution H/T All-Season 245/60R18. With less than 8k miles, both tires developed deformities/bulging on upper sidewal/tread,line intersect, causing vehicle to shimmy. The dot #'s of both tires are up83 1LE 1021 . Tires have a 60k warranty. Cooper tires issues two safety recalls due to sidewall deformities on this tire model, same plant, but in a different sizes. February 26, 2021 cooper tires has issued yet another safety recall on this exact model tire but in a different size. The 2 cooper evolution HT tires seem to also have sidewall defects. I feel that the bulging tires are a safety hazard due to manufacturing defects. I would like to have my 245/60r18 cooper evolution as well as all of the other sizes of this model tire made by cooper, futher reviewed to the recall list
The contact owns a 2009 Mazda CX9. The contact stated while driving at an undisclosed speed, the hot engine temperature warning light illuminated. The contact pulled over and added coolant to the reservoir and waited for the engine to cool down. The warning light remained illuminated. The contact was concerned that the failure was related to the water pump on the vehicle not working as needed. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 120,000.
While driving under normal, dry conditions on highway 540 in north carolina, my right rear copper cs5 ultra touring tire catastrophically failed and separated the tread completely from the sidewall of the tire on my 2009 mazda cx-9.
While pulling a small trailer the car stopped unable to drive the car according to the mechanic the transfer case shattered into pieces
My brakes started feeling spongy but hard to push when I would try to come to a stop. It felt at times like my car wasn't going to stop. I stopped driving it and the brake booster was replaced. At that time, I lost brakes completely. The brake peddle goes all the way to the floor when pressed. Hopefully the booster is a bad one.
I have a problem with the brake light switch. It works for awhile and then stops working. When I press the brake pedal the brake light may or my not come on and that is while sitting still or while the car is moving. I have replaced the switch several times.
I was taking my daughter to high school in the morning with my son in the car as well. In the parking lot of the high school, I applied the brakes but the brakes did not work. My foot was all the way to the floor when they finally caught but I was out in the line of traffic and luckily no one hit me and injured my son or myself. After replacing the rotors and brake pads that did not fix the situation, I have since learned that the brake booster has been an ongoing issue with mazda cx-9 that was even investigated by the federal safety agency without having a recall. How does something so critical in the safety of lives does not generate a recall that the federal safety agency has seen repeated complaints of the same issue without advising or caring about the safety of the consumers and other drivers. It is an ongoing issue that mazda has not addressed or corrected.
Oil and coolant mixed together and cause engine to die with a service code of p0016 which means per the dealer that the engine needs to be replaced. I bought this car brand new and had it service by mazda dealership consistently. This is common issue and mazda manufacturer should be cover this issue for customers.
