My vehicle completely shut off while idling in park with no prior warning to anything being wrong. Put coolant in since the container was empty. Replaced thermostat, but vehicle was still overheating. Had it towed to Flow Mazda of Fayetteville and had them run a diagnostic. They determined that coolant was leaking into the oil due to a broken water pump. It was estimated to cost approximately $5,000 to repair with no guarantee that it would fix the problem. They pulled 4 sludge codes. There is currently a lawsuit against Mazda for this specific problem that was filed in 2019.

I HAVE BEEN EXPERIENCING ISSUES WITH MY BRAKES. VERY HARD TO PUSH, NOT COMING TO A STOP, SOUNDS LIKE AIR & MAKES A HISSING SOUND WHEN BRAKE ARE APPLIED.THE 1ST TIME I NOTICED I WAS DRIVING STRAIGHT ON A 2 LANE ST. A CAR WAS COMING FROM THE OFF RAMP ON THE RIGHT OF ME & CUT ME OFF. I TRIED TO BRAKE BUT, THEY WERE SO HARD TO PUSH DOWN, I HAD TO JUMP INTO THE NEXT LANE IN ORDER TO NOT REAR END HER BUT, BECAUSE I HONKED MY HORN, THE LADY JUMPED INTO HER NEXT LANE CAUSING ME TO HAVE TO CUT BACK OVER AGAIN, ALL THE WHILE MY BRAKES ARE REALLY HARD TO PUSH, THE CAR WOULDN'T STOP. THEY MADE HISSING SOUNDS. I HAD MY MECHANIC CHECK, STATES IT'S THE BRAKE BOOSTER & THERE MAY BE A RECALL. I CHECKED ONLINE, JUST A WARRANTY. MAZDA WILL REPAIR BEFORE 90K OR 7 YEARS. I CALLED MAZDA, WHO SAID THEY ONLY MAKE RECALLS WITH SAFETY ISSUES. I'D SAY THE BRAKES MALFUNCTIONING IS DEFINITELY A SAFETY ISSUE. THE 7 YR EXPIRATION WAS UP IN 2018. WHEN I BOUGHT THE VEHICLE IT ALREADY HAD 105K, SO THE WARRANTY WAS EXPIRED. THAT MAKES NO SENSE. IT SHOULD HAVE BEEN A RECALL. WHAT HAPPENS TO PEOPLE LIKE ME WHO BUY THE MAZDA CX-9 AFTER THE 7 YR OR 90K MILE EXPIRATION? IT DOESN'T APPLY TO US AND WE HAVE TO PAY OUT OF POCKET? KNOWING THAT THIS WAS A SAFETY ISSUE AND THAT IT WAS HAPPENING TO 2010-2011 CX-9 MODELS, IT SHOULD HAVE BEEN DEEMED A RECALL. ESPECIALLY WHEN PEOPLE BUY USED CARS. THIS IS NOT JUST AN ISOLATED ISSUE OR INCIDENT. THIS WAS LITERALLY LISTED BY PEOPLE WITH THE SAME COMPLAINTS. I HAVE NOT BEEN ABLE TO FIX MY VEHICLE. IT'S MY SOURCE OF TRANSPORTATION TO GET TO WORK. I DEFINITELY BELIEVE THIS SHOULD HAVE BEEN A SAFETY RECALL BECAUSE PEOPLE ARE STILL HAVING ISSUES. WHAT IF SOMEONE DIES. WHO'LL BE AT FAULT IF A PERSONS BRAKES GO & THEY GET INTO AN ACCIDENT & GET INJURED OR DIE? THERE HAVE BEEN SO MANY COMPLAINTS REGARDING THIS ISSUE, HOW COULD IT BE DEEMED A WARRANTY AND NOT A SAFETY RECALL?

I EXPERIENCED A SEVERAL BRAKING PROBLEMS IN MY CAR IN THE FALL OF 2020. I TOOK IT TO THE MAZDA DEALERSHIP AND THEY REPLACED THE BRAKING SYSTEM PER MAZDA'S SSP 93 BULLETIN. HOWEVER, MAZDA INFORMED ME THAT MY CAR WAS OUTSIDE OF THE EXTENDED WARRANTY FOR THIS ISSUE AND I HAD TO PAY FOR THE REPAIR MYSELF. I ARGUED THAT IT WAS CLEARLY A SAFETY ISSUE BECAUSE THE BRAKING SYSTEM PERFORMED SO POORLY THAT I NEARLY GOT IN MULTIPLE ACCIDENTS. MAZDA STATED THAT IT WAS NOT A SAFETY ISSUE, THEREFORE NO RECALL WAS NECESSARY, AND I WOULDN'T BE COVERED FOR THE REPAIR. I BELIEVE THE NHTSA NEEDS TO MAKE THIS A FULL SAFETY RECALL. THE BRAKING FAILURE IS VERY DANGEROUS TO DRIVERS AND MAZDA NEEDS TO TAKE FULL RESPONSIBILITY FOR THIS ISSUE.

2010 MAZDA CX-9 AWD TOURING WITH UNDER 120,000 MILES. THE VEHICLE WOULD MAKE A NOISE LIKE DRIVING OVER RUMBLE STRIPS IN THE ROAD, VIBRATING THE UNDERCARRIAGE. IT STARTED HAPPENING WHEN LIGHTLY PRESSING THE ACCELERATOR, TRYING TO MAINTAIN SPEED, NORMALLY AT 1500RPM THEN IT GRADUALLY GOT WORSE AND HAPPENED ALL THE TIME AND THE NOISE GOT LOUDER. SOMETIMES THERE WOULD BE A BURNING SMELL. I SPENT $1000+ ON "FIXES" BEFORE DISCOVERING IT WAS THE TRANSFER CASE, ANOTHER $2,000+. SINCE MAZDA ALREADY KNOWS ABOUT THE ISSUE AND HAS PROVIDED 2 EXTENDED WARRANTIES FOR THIS ISSUE, THE TRANSFER CASE FOR THE DEFECTIVE YEARS/MODELS SHOULD BE ON THEM. AFTER RESEARCHING THIS PROBLEM I HAVE SEEN MANY PEOPLE HAVING TO REPLACE THE TRANSFER CASE MULTIPLE TIMES.

WE WERE SITTING IN A PARKING LOT WAITING ON A PIZZA. WE NOTICED THE A/C WASN'T COOLING, AND THEN NOTICED THE CAR WAS STARTING TO OVERHEAT. (THIS WAS THE FIRST TIME EVER). WE CHECKED THE RADIATOR, IT WAS EMPTY. WE PURCHASED COOLANT AND FILLED UP THE RESERVOIR. NEVER SAW ANY LEAKS. CAR STARTED BUT SEEMED SLUGGISH LIKE THE BATTERY WAS LOW. WE GOT OUR PIZZA AND DROVE ABOUT 6 MILES WHERE WE PARKED TILL WE TOOK IT TO THE DEALER ON MONDAY. OUR MECHANIC CALLED ME LATER TO TELL ME THAT THE WATER PUMP HAD FAILED AND THAT IT HAD LEAKED INTO THE OIL PAN AND WE WOULD HAVE TO HAVE THE ENGINE REPLACED. THE REPAIR TOTAL FOR MY CX9 IS AT $9K. WE HAVE 108,000 MILES ON THE VEHICLE. MY VEHICLE IS STILL SITTING AT THE DEALER.

BRAKE BOOSTER SPONGY...KNOWN MAZDA ISSUE,NHTSA CLOSED ISSUE WHEN MAZDA AGREED TO EXTEND WARRANTY,WITHOUT RECALL. OUR PROBLEM OCCURRED AFTER WARRANTY ENDED...PROVING BRAKE RECALL NEEDS TO HAPPEN!!!! ON JULY 1ST,2020, MY WIFE'S TRIP BACK HOME NEARLY TURNED TRAGIC WHEN THE CAR WOULDN'T BRAKE(FELT SPONGY) DOWN THE HIGHWAY RAMP . FORTUNATELY FOR HER ,THERE WERE NO CARS AT THE INTERSECTION AS THE CAR ZOOMED RIGHT AT 60 MPH .EVENTUALLY,SHE WAS ABLE TO MANEUVER IT TO THE RIGHT LANE AND DROVE IT HOME WITH HAZARD LIGHTS ON. RIGHTFULLY DISTRAUGHT ABOUT THE WHOLE ORDEAL ,WE HAD TO THANK OUR STARS FOR HAVING HER HOME ALIVE AND WITHOUT CAUSING INJURY/DEATH TO OTHERS. ON MY DRIVE TO THE MECHANICS I HEARD AIR HISSING AND FELT THE BRAKE REALLY HARD TO PUSH. AGAIN HAZARD LIGHTS/ MANUAL DRIVE GOT US THERE. THE MECHANICS IMMEDIATELY SUGGESTED THAT THIS IS A KNOWN PROBLEM WITH MAZDA CX-9 AND THAT MAZDA WAS AWARE OF IT. HE SAID THAT MAZDA HAD PROVIDED EXTENDED WARRANTY FOR CUSTOMERS WHO HAD THE ISSUE UNTIL MARCH 2015. WE WERE GROSSLY UNAWARE OF ANY OF THIS,AS WE NEVER HAD THE PROBLEM UNTIL THIS JULY. NOT SURE HOW WE WENT ON FOR SO LONG WITHOUT ANY PROBLEM( MAY BE PROPER CARE/USE?),BUT ANY ISSUE WITH A BRAKE SHOULD HAVE BEEN ADDRESSED BY A COMPLETE RECALL ,NOT BY JUST PROVIDING EXTENDED WARRANTY FOR A LIMITED TIME ,JUST FOR PEOPLE CURRENTLY EXPERIENCING THE ISSUE.MAZDA CUSTOMER SERVICE DOWNPLAYED THE COMPLAINT AS OWNER'S EXPENSE AS WE DID NOT HAVE THE WARRANTY. OUR SITUATION PROVES THAT BRAKE ISSUES ARE NOT SOLVED BY EXTENDING WARRANTY,AND THE ONLY WAY TO ADDRESS THIS IS BY ISSUING A RECALL AND CORRECTING THE PROBLEM. IN ADDITION, THERE MIGHT BE MANY MORE MAZDA OWNERS STILL DRIVING THEIR VEHICLES,COMPLETELY UNAWARE OF THIS PROBLEM,THUS CONSTITUTING HAZARDOUS DRIVING CONDITIONS. THE NEXT TIME WE MIGHT NOT BE AS LUCKY TO ESCAPE WITHOUT INJURY/DEATH.

3PE19006 · 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.

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.

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
PE14005 · Brake Booster Failure
Opened Feb 10, 2014 · Closed Jun 26, 2014
Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist
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
