MY BRAKE FEELS LIKE IT HAS AIR UNDER IT AND IS HARD TO PRESS DOWN ON. IT ALSO MAKES A HISSING SOUND. WHEN STOPPED AT A TRAFFIC LIGHT, WITH MY FOOT ON THE BRAKE, IT FEELS LIKE MY CAR IS TRYING TO MOVE. I AM SCARED MY BRAKE WILL FAIL OR NOT WORK WHEN I PUSH ON IT. I NOTICED THIS ABOUT A WEEK AND A HALF AGO. I THOUGHT IT WAS NOTHING AT FIRST BUT IT IS STILL DOING THIS AND MORE FREQUENTLY. I AM CONCERNED THAT THIS WILL CAUSE AN ACCIDENT. I AM WORRIED SOMETHING WILL HAPPEN TO MY CHILDREN OR ME IF MY BRAKES FAIL BECAUSE OF THIS.

RECENTLY, THE BRAKE PEDAL FEELS SOFT AND I HAVE TO STEP ON IT ALL THE WAY FOR THE CAR TO SLOWLY SLOWDOWN. BEEN IN VERY CLOSE SITUATIONS RECENTLY. I CHECKED THE BRAKE FLUID AND IT WAS LOW, SO I REFILLED IT AND TOOK IT OUT FOR A DRIVE... THIS DID VERY LITTLE. THE BRAKE PEDAL STILL MAKES A HISSING SOUND AND FEELS VERY SPONGY. IT IS NOW MAKING A BRAND NEW SOUND TOO. WHEN I STEP ON THE BRAKE PEDAL ALL THE WAY, IT MAKES A WHISTLING SOUND. VERY HIGH PITCH WHISTLING SOUND LIKE A LOT OF AIR IS TRYING TO SQUEEZE OUT OF A TINY HOLE. IF THIS IS A COMMON PROBLEM, THEY NEED TO GET THIS CAR RECALLED BECAUSE I USE IT TO TRANSPORT MY LITTLE ONES AROUND.

I WAS DRIVING HOME FROM WORK TODAY. WHEN I APPROACHED A TRAFFIC LIGHT, I DEPRESSED THE BRAKE PEDAL AND HAD TO PRESS IT VERY HARD FOR THE CAR TO STOP. GOOD THING THERE WAS NOBODY IN FRONT OF ME BECAUSE I WOULD HAVE HIT THEM. AS I STARTED TO GO AGAIN AND PROCEED TO ANOTHER LIGHT, AS I PUSHED THE BRAKE PEDAL, I HEARD A 'HISSING' SOUND COMING FROM THE PEDAL. IT ALMOST SOUNDED LIKE AIR COMING OUT OF A TIRE. THIS WAS ALARMING TO ME BECAUSE I FELT AS IF MY BRAKES WERE GIVING OUT. I HAD TO PRESS VERY HARD ON THE BRAKE AND AS IT BRAKED, IT WAS SO SUDDEN IT SHOVED ME FORWARD IN THE SEAT. I TOOK IT RIGHT OVER TO OUR SERVICE SHOP IN TOWN, AND AFTER HE TOOK THE CAR FOR A TEST DRIVE, HE DROVE IT RIGHT BACK AND PROCEEDED TO TELL ME THAT IT SOUNDS LIKE THE BRAKE BOOSTER WAS GOING. HE ADVISED ME NOT TO DRIVE THE CAR AND TO CALL AAA AND HAVE IT TOWED TO THE DEALER. I MANAGED TO GET IT BACK HOME, VERY SLOWLY, AND INTO THE GARAGE. THIS IS VERY FRIGHTENING TO ME BECAUSE MY DAUGHTER ALSO DRIVES THIS CAR ON OCCASION AND WHAT IF THE BRAKES FAILED WHILE SHE WAS DRIVING?! IN READING ALL THE POSTS WITH CUSTOMERS HAVING THIS SAME ISSUE WITH THE BRAKES, I THINK MAZDA NEEDS TO RECALL THIS PART BEFORE THEY HAVE A BIGGER LAWSUIT ON THEIR HANDS! I WILL BE CALLING THE DEALERSHIP FIRST THING TOMORROW MORNING.

I REVERSED MY VEHICLE INTO A PARKING SPOT AND STARTED HEARING ABNORMAL NOISE LIKE BRAKES GRINDING, BUT WAS STILL PRESENT EVEN WHEN NOT MOVING. HAVING A CAR BACKROUND I KNEW IT WAS MORE LIKE AIR. WASN'T SURE WHAT IT WAS, BUT BECAUSE I ALREADY WORK AT A DEALERSHIP I DECIDED TO HAVE ONE OF MY DIAGNOSTIC TECHS CHECK IT OUT. HE KNEW RIGHT FROM MY DESCRIPTION THAT IT WAS PROBABLY BRAKE BOOSTER RELATED. CALLED MY DEALERSHIP THAT ALWAYS SERVICES MY CAR FOR AN EMERGENCY DROP OFF. BRINGING THE VEHICLE TO THE DEALERSHIP, EVERY TIME I BRAKED THE PEDAL WOULD NOT GO DOWN ALL THE WAY, GO STRAIGHT TO THE FLOOR, OR I'D HAVE TO DOUBLE TAP THE BRAKES SIMILIAR TO IF I WAS DRIVING ON ICE. WHEN AT STOPS I'D HEAR THE AIR NOISE FROM THE BOOSTER, AND EVEN WHEN THE VEHICLE WAS OFF THE PEDAL GOES TO THE FLOOR. SOMETIMES I'D BE COMING TO A STOP AND THE BRAKES WOULD GRAB SUDDENLY AND I'D SLIDE FORWARD ON THE SEAT & MOST LIKELY INTO THE STEERING WHEEL IF I DIDN'T HAVE MY SEATBELT ON. THE PROBLEMS WITH THE BRAKE HAPPENED AT SUDDEN STOPS, SLOW STOPS, AND THE NOISE OF AIR WAS PRESENT AT ALL BRAKING. CHECK ONLINE FOR TSB BRAKES FOR MY VEHICLE AND SEE IT IS BECOMING A COMMON THING. VEHICLE IS AT THE DEALERSHIP CURRENTLY & IS OUT OF WARRANTY, BUT WITH THIS BEING SUCH A WELL NOTED CONCERN & OTHER ISSUES I'VE HAD I DON'T KNOW WHAT I WILL DO.

BRAKES FELT EXTREMELY SLUGGISH FOR THE REST OF MY MORNING DRIVE (DROPPING OFF MY DAUGHTER AT HER SCHOOL). AT A STOPLIGHT THE CAR STALLED, WHICH HAS NEVER HAPPENED BEFORE. TOOK IT TO MY MECHANIC WHO SAID THE COMPUTER WAS KICKING OUT MULTIPLE CODES WHICH SEEMED TO BE RELATED TO THE BRAKE BOOSTER SYSTEM. HE RECOMMEND I TAKE THE VEHICLE TO A LOCAL MAZDA DEALERSHIP B/C IT MIGHT STILL BE UNDER WARRANTY. THE MAZDA DEALER JUST CONFIRMED THAT THE PROBLEM IS RELATED TO THE SUPPOSEDLY KNOWN FAULTY BRAKE BOOSTER SYSTEM AND A LEAK IN THE VACUUM. MAZDA WILL REPLACE THE PARTS FOR FREE AND NOT CHARGE ANY LABOR, EITHER. VERY SCARY ISSUE -- I NEARLY HIT SEVERAL VEHICLES ON MY DRIVE THIS MORNING AND WAS LUCKY THAT THE CARS IN FRONT OF MY MOVED TO AVOID AN ACCIDENT. MAZDA NEEDS TO RECALL ALL CARS WITH THIS ISSUE BEFORE SOMEONE IS INJURED, OR WORSE. *TR

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.

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.

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
