The front driver-side lower ball joint suffered a catastrophic structural failure and sheared completely apart while moving. This vehicle was previously serviced under Safety Recall Campaign 15V451000 / Mazda Recall 8515G for this exact defect. The recall remedy part failed a second time, collapsing the front wheel assembly, ripping the CV axle completely out of the transmission casing, causing a hazardous transmission fluid spill, and leaving the vehicle stranded and immobilized in the middle of a live roadway in the dark

I had an issue with the AWD not engaging and the 4x4 light illuminating when driving on snow and ice. No indicators when driving under normal conditions. I had no traction and had difficulty maintaining control of the vehicle while driving at speeds less than 25 mph. I had difficulty gettting momentum from a stop as the tires were spinning and engaging tracion. I took the car into a Mazda dealership for a full circle inspection and found that the 4x4 light was illuminating due to worn-out splines connecting the transfer case. The technician was able to spin the driveshaft, indicating the splines are damaged and need to be replaced. Recommendations were to replace the transmission and transfer case with a repair estimate of $5469.61. Additionally, the technician observed some seeping of oil coming from the tiing cover and reccommends re-sealing it as well as replacing the water pump ( another known failure issue in which Mazda is aware of). Cost estimate of $4319.78. The technician also observed a crack in the right rear differential mount with a repair cost of $442.10. In short, Mazda knew about all these problems. They issued a warrenty extention from my research back in 2014 but never issued any recalls. In short, I didn't own this vehicle in 2014, I purchased in 2016. I was never aware of any warrenty extentions to include these issues and if I was aware, I would have had the services done for repairs. My safety as well as my family's and others are at risk if I lose control of the vehicle due to the AWD not engaging when needed.

Driving kids to school a few months ago. Car started to smell like burning rubber. I thought it was the garbage truck ahead of us. As we turned the corner 2 blocks later, the car dead stopped and we all went flying forward. It jerked so hard, we are lucky our necks didn't snap. I put the car in park and turned it off. I waited a few minutes as I was too worked up, and started the car again. We got about 50ft before a very loud noise began, almost as if something was dragging underneath. I stopped, and had it towed home. I then had it towed to mechanic. They said bad TRANSFER CASE & DRIVE SHAFT. - TRANS PAN GASKET. I am a single mom with no money to afford to have it fixed in fear of it going bad again. They quoted me 3,500 here in PA.

Braking trouble recent in weeks in 2011 Mazda CX-9 vehicle. Had mechanic (Euro Motorsports in Chagrin Falls OH) check it out. Turned out to be a faulty Brake Booster. Mechanic test drove car; braking failed and he almost rear-ended another vehicle. He found on line a Mazda service notice dating from April 4, 2014 called SSP93. Mazda issued an extended warranty of 7 years or 90,000 miles, whichever came first, to have defective part replaced by an improved part. But we were never informed by Mazda of Bedford, where we bought the vehicle. Currently, our vehicle has about 83,000 miles. Never knew there was a problem until recent trouble with the braking. There are thousands of CX-5, Cx-7, and Cx-9 vehicles in operation in U.S. right now; probably many owners have no idea there is a brake defect in their vehicles that could cause a serious accident, potentially fatal. Mazda should have done a recall in 2014, not an extended warranty. Although Brake Boosters are supposedly good for at least 150,000 miles of driving, our brake failure at around 83,000 miles proves otherwise. NHTSA should order Mazda to recall all vehicles with the defective brake part and replace them at Mazda's expense, probably hundreds of dollars each time. We do not want to have our brake booster replaced by our regular Euro Motosports mechanics because a recall must typically be repaired by the dealer. We already filed a complaint with State of Ohio Attorney General's office, but their people say the complaint must first go through BBB. No urgency on their part at all, even when informed potentially fatal flaw in the brakes. To avoid dangerous accidents, NHTSA should act more swiftly. Thanks.

Defective water pump located inside the engine that when failure occurs can cause coolant to leak into engine causing complete engine failure. This is a major safety hazard due to the fact that these cars with defective water pumps can break down with very little warning in the middle of a freeway! I have contacted Mazda who refuses to do anything due to it being outside warranty but will not acknowledge the safety concern sudden engine failure can cause on a perfectly maintained car. In California there is currently a lawsuit against Mazda for this issue and hundreds of other Ford and Mazda owners who have been caught in very dangerous situations due to this water pump failure issue. The situation we were involved in could have gone very differently and that was my family in the vehicle that Mazda seems to care about a couple thousand dollars more then the value of life... is just ridiculous! Please do the research yourself so no one has to loose their life over this.

AFTER HAVING IT TOWED TO MY MECHANIC, IT WAS DETERMINE THE PROBLEM WAS THE TRANSFER CASE. THE SPLINES BETWEEN THE TRANSMISSION AND TRANSFER CASE HAD BEEN EATEN AWAY BY RUST. THE SEAL HAD NOT KEPT WATER OUT AS IT WAS DESIGNED TO DO. A NEW TRANSFER CASE WAS ORDERED AS WELL AS A NEW TRANSMISSION. THE REPLACEMENT TRANSFER CASE HAD SHOWN SIGNS OF THE SAME ISSUES WITH THE SPLINES. ANOTHER (2ND ONE) TRANSFER CASE HAD TO BE ORDERED. I HAD PURCHASED THIS CAR IN FEBRUARY 2019 USED. THE CAR HAD A CLEAN TITLE, NO ACCIDENTS AND WAS SERVICED REGULARLY. WITHIN 1 YEAR, I HAD TO PAY OUT $5,000.00 TO REPLACE TRANSFER CASE AND TRANSMISSION. I LOST THE USE OF MY CAR FOR OVER 3 WEEKS (DUE TO THE PROBLEMS WITH GETTING A TRANSFER CASE THAT WAS GOOD). WHEN YOU GOOGLE THIS ISSUE, MANY PEOPLE HAVE HAD SIMILAR ISSUES.

I NOTICED A SIGNIFICANT PROBLEM BRAKING ON MY CX9 TO WHERE I HAD TO ALMOST STAND ON THE BRAKE PEDAL TO STOP. ADDED BRAKE FLUID HOPING THAT WOULD HELP BUT DID NOT. TOOK IT TO MAZDA DEALERSHIP IN BUFORD,GA AND THEY CONFIRMED THE BRAKE BOOSTER WAS CAUSING THE PROBLEM AND STRONGLY RECOMMENDED REPLACEMENT ASAP. THEY EXPLAINED THE PROBLEM IS A KNOWN ISSUE AND MAZDA EXTENDED THE WARRANTY TO 90K MILES. THE PROBLEM FOR ME WAS MY '11 CX9 HAD 107K. I HAD NO CHOICE BUT TO PAY TO HAVE THE PROBLEM FIXED DUE TO MY PERSONAL SAFETY. A COUPLE DAYS LATER I CALLED MAZDA CUSTOMER EXPERIENCE AND VOICED MY DISAPPOINTMENT THAT THIS PART WAS NEVER RECALLED AND PEOPLE ARE DRIVING AROUND IN UNSAFE CX9'S. THEY DID CONFESS THAT IF I WOULD HAVE CALLED THEM 'BEFORE' MY REPAIR THEY COULD HAVE REVIEWED THE ISSUE AND PERHAPS OFFSET SOME OF THE COST. THIS LEFT ME VERY DISAPPOINTED SINCE THEY WOULD HAVE PREFERRED I KEPT DRIVING THE CAR AND RISKED INJURY TO OTHERS WHILE THEY REVIEWED THE CASE. #CX9SADNESS

IN DEC. 2018, I HAD MY 2011 MAZDA CX-9 TO A MAZDA DEALER SERVICE SHOP FOR WHAT I FELT LIKE A SPONGY BRAKE PEDAL. WHEN I PICKED UP THE CAR THE SERVICE ADVISOR TOLD BE THERE IS NOTHING WRONG WITH THE CAR'S BRAKES. AFTER A FEW MONTHS, WHILE THE SYMPTOM PERSISTED, I FOUND OUT THERE IS A KNOW ISSUE WITH THE BRAKE BOOSTER, WHICH MAZDA ACKNOWLEDGED AND ISSUED A WARRANTY EXTENSION (WHICH IS EXPIRED NOW). TWO DAYS AGO, WHILE TRAVELING IN TRAFFIC ON HIGHWAY, I HAD TO STOP THE CAR DUE TO A SUDDEN TRAFFIC JAM AND I FELT THE BRAKES BEING INSUFFICIENTLY EFFECTIVE TO STOP MY CAR SAFELY. AS SUCH, I PUMPED THE BRAKE PEDAL 3-4 TIMES AND THAT CAUSED THE PEDAL TO BECOME VERY HARD AND MADE MATTERS WORST- TO A POINT WHERE I HAD TO PULL ON THE SHOULDER TO AVOID REAR-ENDING THE VEHICLE IN FRONT OF ME.

OUR VEHICLE HAS WATER DRAINS OR "WEEP" LINES FOR THE SUNROOF. WE RECENTLY HAD THE ELECTRICAL SYSTEM STOP/START, DASH LIGHTS REMAIN ON CONSTANTLY AFTER SITTING IN THE DRIVEWAY DURING THE RAIN. WE LEARNED THAT IF THE DRAINS BECOME BLOCKED THAT WATER LEAKS INTO THE CABIN DIRECTLY ONTO THE BODY CONTROL MODULE (BCM). BECAUSE THE BCM IS NOT IN A SEALED OR WATER-PROOF CASE, YET IS SOAKED IN THESE CONDITIONS, THE VEHICLE IS SUBJECT TO ELECTRICAL FAILURE AS A RESULT. REPLACING THE BCM COSTS ABOUT $1,000. WHEN WE STARTED THE CAR THE DASH LIGHTS THAT WARN OF AN ISSUE WITH MANY OF THE VEHICLES SAFETY SYSTEMS REMAINED ON. OTHERS WENT OFF AND SOFT OF FLASHED. WE COULD NOT DETERMINE IF THERE WAS REALLY AN ISSUE WITH ALL OF THE COMPONENTS FLASHING ON THE DASH SO WE DID NOT WANT TO DRIVE IT FOR FEAR OF AN ACCIDENT. OUR VEHICLE WAS STATIONARY (THANK GOD). WE WAITED FOR A WHILE AND WERE ABLE TO LEAVE FOR HOME, BUT THIS CONDITION IS CLEARLY A HUGE SAFETY RISK.

Investigations
3 NHTSA investigations on record
Investigations are agency reviews, not findings that a vehicle is defective.
The Office of Defects Investigation (ODI) opened this Preliminary Evaluation (PE19-006) on May 2, 2019 to investigate two Vehicle Owner Questionnaires (VOQs) and Early Warning Reporting data related to allegations of inadvertent deployment (IAD) of side curtain airbags in Model Year (MY) 2010 through 2013 Mazda CX-9 vehicles. ODI sent an Information Request (IR) to Mazda North America Operations, LLC. to gather information about the alleged defect in the subject vehicles. In the 20 months since opening the PE, ODI has received three additional VOQs. To date, there have been a total of 11 IAD incidents within the identified population of 104,360 vehicles. Of the 11 incidents, no serious injuries were reported. The last known incident occurred in December 2020.Mazda's response to ODI's IR letter identified the root cause as a manufacturing issue of the Bosch SMG076 Roll Rate Sensor within the Restraint Control Module (RCM). During the manufacturing calibration process, small particles may be generated that could affect roll sensor capacitance, which could lead to a loss of curtain airbag protection or an erroneous deployment command. On November 19, 2012, a revised Roll Rate Sensor calibration process was launched, establishing a clean point for the issue. In its responses to ODI, Mazda has assessed the condition as a low risk to motor vehicle safety, with low incident frequency not warranting action. Any RCM data indicating a malfunctioning Roll Rate Sensor will result in the illumination of the airbag warning light. In the event of an erroneous curtain airbag deployment, there is no contact with properly seated occupants. Additionally, the condition is not affected by deterioration or wear, and known incidents established a random pattern of occurrence.During the investigation, ODI examined the injury risk to vehicle occupants from curtain airbag deployments. It was determined that the subject vehicles do not pose a substantial risk to out of position occupants, as testing data falls within Technical Working Group (TWG) reference values. Modeling simulation based on data provided by Mazda for properly seated occupants during static and dynamic airbag deployments indicated sufficient head clearance and no risk of brain injury. ODI analysis reveals that inadvertent deployment incident rates of curtain airbags in the subject vehicles are low through approximately ten years in service. Incident frequency does not meet values warranting recall action, but rather align closely with baseline frequency of general inadvertent deployments which are known to occur in rare driving conditions. Additionally, warranty analysis of RCM failures resulting in a loss of curtain airbag protection revealed low claim rates.Based on the analysis conducted, this investigation has been closed. The closing of this investigation does not foreclose the Agency from taking further action, if warranted, or the potential for a future finding that a safety-related defect exists, based upon additional information the Agency may receive.The five ODI complaints cited above can be reviewed at NHTSA.gov under the following identification numbers: 10905492, 11165925, 11270089, 11310044, 11385219.
In an July 7,2015 letter to NHTSA, 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 (NHTSA 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
In March 2014, Mazda Motor Corporation (Mazda) initiated Special Service Program SSP93 to extend the warranty coverage for a specific brake booster fault condition on model year (MY) 2007-2013 Mazda CX-9 vehicles.According to Mazda's dealer communication for SSP93, the subject vehicles may exhibit a condition were the brake pedal is harder than usual to depress. Complainants report hearing air leakage (hissing) from the driver-side foot area during braking.The Mazda program extends the warranty coverage for repairing this condition to unlimited time and mileage for repairs performed between March 31, 2014 and March 31, 2015 and to 7 years or 90,000 miles for repairs performed after March 31, 2015.In its response to the Office of Defects Investigation's (ODI) information request letter for PE14-005, Mazda identified a problem with booster diaphragms developing tears near the outer seal/circumference that can result in noise and degraded booster performance as the tears grow in length (Figures 1-3).The tears allow leakage from the ambient to the vacuum sides of the diaphragm that reduces the differential pressure across the diaphragm and produces a hissing noise after the tears have reached 10-12 mm in length.The problem was caused by wear of the mold used for the diaphragm forming process, which resulted in increased thickness and stress in the bending area of the diaphragm.Continuous operation in environments with high ambient temperatures accelerates the hardening of the diaphragm material, further increasing the stress in the bending area and contributing to tear initiation and propagation rate.Analysis of failure data indicates that the tool wear condition affected vehicles produced after June 2010 and operated in hot states (Figures 4-6).In February 2013 the supplier introduced a new mold and changes to the diaphragm thickness monitoring process to correct the condition in production vehicles.Analysis of complaint and supplier test data indicates that the diaphragm tear condition is a progressive failure that develops slowly over time.Smaller tears have little effect on system performance.As the tear continues to grow, the effects become more evident.The hard pedal and increased effort are experienced during initial pedal application, but are diminished as the pedal is pressed further by the driver and the tear is partially sealed by the outer wall of the booster.This change from a hard to a soft pedal feel is described by some drivers as a spongy pedal.For tear lengths that were observed in warranty return parts, testing demonstrated that most booster performance can be recovered with increasing pedal apply speed and apply force.None of the tears measured in return parts grew large enough to cause a complete loss of brake booster function. The booster diaphragm tear condition results in partial reduction in booster function that progresses gradually over time with audible and pedal feel symptoms available to the driver.The condition does not result in a sudden loss of power braking assist.The effects are evident during initial pedal apply and are reduced by increased pedal apply force and rate.ODI has not identified any accidents associated with the booster diaphragm tear condition in the subject vehicles.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will continue to monitor complaints and other information relating to the alleged defect and take further action in the future if warranted.VOQs (24) associated with this investigation:10482005, 10486941, 1048793
