WHEN BRAKING THE BRAKES ARE EITHER HARD AND DO NOT WORK OR BRAKES ARE SPONGY, WILL SLOW VEHICLE, BUT WILL NOT GIVE YOU CONFIDENCE THAT THEY WILL STOP THE VEHICLE LIKE THEY SHOULD. WHEN BRAKING AT TIMES YOU CAN HEAR A HISSING, MAYBE ALL THE TIME, BUT WHEN THINGS ARE HAPPENING YOU AREN'T LISTENING FOR A HISSING SOUND. ALSO, WHEN THE VEHICLE IS STATIONARY AND IN PARK IF YOU REALLY PUT YOU FOOT TO THE FLOOR A BEEPING ALMOST LIKE AN ALARM SOUND IS MADE. THIS BRAKE BOOSTER FAILURE SHOULD BE A MAJOR CONCERN. 8-13-2017 I WAS TRAVELING ABOUT 65 MPH IN LITE TRAFFIC ON A DOWNGRADE AND SLIGHT CORNER WHEN A VEHICLE IN FRONT OF ME LOST A TIRE AND I NEEDED TO BRAKE QUICKLY AND MY BRAKE PEDAL WOULDN'T MOVE, IT WAS HARD AS A ROCK, NEVER SLOWED THE VEHICLE AT ALL. THANK GOODNESS I HAD PLENTY OF ROOM TO MANEUVER, OTHERWISE WHO KNOWS WHAT THE RESULT OF THAT ACCIDENT MAY HAVE BEEN. ANOTHER TIME WAS 8-30-2017 I WAS DRIVING MY VEHICLE, APPROX 20 MPH, AND WAS APPROACHING THE INTERSECTION OF OUR SUBDIVISION AND THE HWY WHERE THE TRAFFIC TRAVELS AT 55 MPH, I WENT TO BRAKE AND THE PEDAL WENT TO THE FLOOR.... AGAIN NO BRAKES. MY VEHICLE ROLLED TO A COMPLETE STOP, BUT NOT BEFORE I CROSSED INTO THE SECOND LANE OF CROSS TRAFFIC. AGAIN THANK GOODNESS IT WAS AROUND 6:30 AM AND TRAFFIC WAS FAIRLY LITE. MIND YOU THIS IS ONLY TWO OF THE MORE EXTREME TIMES. I HAVE PURCHASED A NEW BRAKE BOOSTER AND IT WILL BE INSTALLED THIS WEEKEND. I DID TRY TO CONTACT MAZDA, BUT AFTER SITTING ON HOLD, 1-800-222-5500, FOR OVER 18 MINUTES THE PHONE FINALLY RINGS.....UNTIL IT DISCONNECTS.

PE19006 · Inadvertent Curtain Air Bag Deployment

Opened May 2, 2019 · Closed Jan 15, 2021

Status: closed (inferred from source dates) · Air Bags; Air Bags:side/window; Air Bags:side/window:curtain

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.

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.

PE15022 · Lower Ball Joint Separation

Opened Jun 9, 2015 · Closed Aug 20, 2015

Status: closed (inferred from source dates) · Suspension:front:control Arm:lower Ball Joint

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
