I EXPERIENCED UNEXPLAINED SUDDEN ACCELERATION WHILE STOPPED AT A STOP LIGHT. AT THE TIME OF THE INCIDENT THERE WAS ONE CAR STOPPED IN FRONT OF ME AND ONE BEHIND ME. FROM THE ONSET OF THE INCIDENT IT TOOK JUST A VERY FEW SECONDS, PROBABLY BETWEEN TWO AND FOUR, FOR THE ENGINE TO REV TO AN EXTREMELY HIGH SPEED. WHILE THIS WAS HAPPENINGS I COULD FEEL THE VEHICLE ATTEMPTING TO MOVE FORWARD FORCEFULLY WHILE I WAS APPLYING THE BRAKES VERY HARD. I SHIFTED INTO NEUTRAL AND TURNED OFF THE IGNITION. I THEN SHIFTED INTO PARK. I TURNED THE IGNITION ON AGAIN AND THE ENGINE CONTINUED TO REV AT A VERY HIGH SPEED. I IMMEDIATELY SHUT OFF THE ENGINE. I DECIDED TO START THE VEHICLE ONE MORE TIME. THIS TIME WHEN I TURNED ON THE IGNITION THE VEHICLE RAN NORMALLY. I CAUTIOUSLY DROVE IT FOR POSSIBLY FIVE MILES AND PARKED IT WHERE I COULD HAVE IT TOWED TO THE DEALERSHIP. I WAS ASKED ABOUT FLOOR MATS.THE ORIGINAL FLOOR MATS WERE IN THE VERY BACK OF THE VEHICLE AND I HAD WEATHERTECH MATS, IN THE FRONT OF THE CAR, WHICH WERE ATTACHED TO HOOKS IN THE FLOOR HOLDING THEN IN PLACE. THE DEALERSHIP DID TAKE THE SITUATION VERY SERIOUSLY. THEY DID INDICATED CONCERN ABOUT HAVING THE VEHICLE ON THE ROAD AGAIN. THEY TESTED THE VEHICLE FOR ANY COMPUTER CODES WHICH MIGHT INDICATE WHAT MAY HAVE CAUSED THE PROBLEM AND FOUND NOTHING. THEY CONTACTED MAZDA AND AT THE TIME THAT I SOLD THE CAR BACK TO THE DEALERSHIP THEY HAD NOT HEARD ANYTHING FROM MAZDA.

PULLED OUT OF MY DRIVEWAY THIS MORNING AND TRIED TO USE MY BRAKES -- HEARD A HISSING, SQUEAKING SOUND AND THE CAR DIDN'T STOP. I PUMPED THE BRAKES SEVERAL TIMES WAS ABLE TO SLOW THE VEHICLE DOWN. 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

FOR THE PAST WEEK, MY 2012 MAZDA CX-9 HAS BEEN HAVING ISSUES WITH NOT BRAKING. AT FIRST, I THOUGHT IT WAS JUST MY IMAGINATION, BUT EVERY DAY THIS PAS WEEK, AT LEAST ONCE A DAY, I GO TO PUSH ON THE BRAKE PEDAL AND IT WON'T MOVE. THE BRAKE PEDAL IS STIFF AS IF I'M PUSHING ON A BLOCK OF CEMENT. IT'S VERY SCARY, AND I'VE ALMOST HIT SEVERAL CARS, AND EVEN ALMOST HIT A PEDESTRIAN. I AM A MOM AND DRIVE WITH MY SMALL CHILDREN IN THE CAR OFTEN. THAT'S WHY I BOUGHT A FAMILY VEHICLE. TODAY I WAS AT A DRIVE THRU WINDOW, AND THE CAR STALLED COMPLETELY. I TURNED THE IGNITION, AND IT STARTED UP, BUT THE ENGINE WAS SHAKY, NOT IDLING RIGHT. IT FELT LIKE IT WOULD STALL AGAIN AT ANY MOMENT. I CALLED MAZDA, BUT MY CAR HAS 40K MILES, AND THEY WERE VERY RUDE AND SAID MY WARRANTY EXPIRED AT 36K MILES. I TOOK IT TO OUR FAMILY FRIEND WHO IS A MECHANIC, AND WHEN I TOLD HIM ABOUT THE BRAKE PROBLEM AND THE STALLING, HE SAID HE KNEW EXACTLY WHAT WAS WRONG. THERE WAS A LEAK IN THE VACUUM SYSTEM ON THE BRAKE BOOSTER, AND THE STALL AND THE BRAKE PROBLEM ARE BOTH CAUSED BY THAT. I WENT ONLINE AND DID RESEARCH, AND FOUND THIS SITE, AND THAT OTHERS ARE HAVING THIS PROBLEM. I CALLED MAZDA BACK AND GOT HE SAME RUDE SERVICE GUY. I EXPLAINED WHAT I HAD FOUND ON THIS SITE, AND HE SAID, WELL THIS MORNING WHEN YOU CALLED, YOU ONLY TOLD ME ABOUT THE STALL, YOU DIDN'T TELL ME YOU WERE HAVING BRAKING PROBLEMS. HE ACKNOWLEDGED THAT THERE WAS A PROBLEM WITH THE BRAKE BOOSTER AND CHECKED MY VIN TO BE SURE MY CAR WAS COVERED UNDER THE NEWLY EXTENDED WARRANTY ON THE BRAKE BOOSTER. I'M TAKING IT IN TOMORROW FOR THEM TO REPAIR IT FREE OF CHARGE. THIS IS EXTREMELY SCARY AND I HOPE THE NHTSA WILL DO A RECALL ON THIS!!! MYSELF OR MY FAMILY COULD HAVE BEEN SEVERELY INJURED IN AN ACCIDENT, OR I COULD HAVE INJURED SOMEONE ELSE!!! *TR

ABOUT THIS TIME I WAS PREPARING TO ENTER A TURN LANE WHEN THE CAR SUDDENLY LURCHED AND MADE AN AWFUL NOISE THAT LITERALLY SOUNDED LIKE THE ENGINE FELL OUT.

THANKFULLY THE LIGHT AT THE INTERSECTION HAD BEEN RED AND TRAFFIC WAS SLOWING WITH ME BECAUSE I SHUDDER AT THE THOUGHT IF TRAFFIC HAD BEEN MOVING AT THE REGULAR RATE OF SPEED. MAZDA ROADSIDE ASSISTANCE HAD IT TOWED TO THE DEALERSHIP WHERE THE TWO GUYS IMMEDIATELY ASKED IF IT WAS AN AWD MODEL. THEY SAID THAT WITHOUT EVEN LOOKING AT IT, BASED ON WHAT I'D SAID HAPPENED, THEY'D BET IT WAS THE TRANSFER CASE. THANKFULLY THE TC WAS STILL UNDER THE POWER TRAIN WARRANTY, BUT IT SEEMS LIKE MAZDA IS AWARE OF THIS ISSUE. WOULD HAVE SERIOUSLY BEEN NICE TO BE ALERTED TO SUCH A POTENTIALLY DANGEROUS DEFECT.

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.

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.

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
