Crash

While driving the side airbags exploded and I had to stop in the middle of the street, get vehicle towed to mazda dealer in Alpharetta, GA Now, im without a vehicle. What do I do now?

The contact owns a 2011 Mazda CX-9. The contact stated that while driving at an undisclosed speed and making a turn, the contact lost control of the vehicle, and the front driver's side suspension lowered to the ground. The vehicle was towed to an independent mechanic, who determined that the subframe was severely rusted, causing the control arm to detach. The contact was informed that the subframe needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 125,000.

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.

Brake booster failure. The power assisted braking has stopped working. There are no leaking vacuum hoses and the check valve is working. The brake pedal travels to the floorboard.

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.

The contact owns a 2011 Mazda CX-9. The contact stated while driving 20 MPH, there was an abnormal sound coming from the brakes. The contact stated that the brake pedal was firm and difficult to depress while attempting to stop the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was contacted, and a case was filed. The failure mileage was 67,000.

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.

The front door windows no longer work. Most recently, the drivers side back door will NOT open. The lock is completely jammed - will not open or shut, which is a safety hazard for my child. The plastic parts in this car are failing and putting my family at risk.

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.

When getting off highway engine began to knock. Engine stalled and would not restart. Upon inspection the water pump was found to have failed and leaked engine coolant into oil. This caused engine to have a complete failure. No check engine light illuminated but when car was scanned multiple codes were found. The car was also found to have a bad Transfer Case.

The contact owns a 2011 Mazda CX-9. The contact stated while driving 60 mph, upon approaching oncoming traffic, the vehicle unexpectedly shut-off. The contact was able to restart the vehicle and pulled the vehicle off to the shoulder. The contact stated that upon restarting the vehicle, the check engine warning light illuminated. Due to the failure and the warning light, the contact had the vehicle towed to an independent mechanic. Upon inspection of the vehicle, the mechanic informed her that coolant had leaked into the oil cylinder and they referred her to a dealer for assistance. The contact then had the vehicle towed to the dealer where they diagnosed the vehicle with a defective water pump as well as engine failure. The manufacturer was also notified of the failure and stated that the failure was caused due to poor maintenance. No further assistance was provided. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 144,000.

WATER PUMP LEAKING IN ENGINE MIXING WITH OIL

I PURCHASED A VEHICLE FROM A BUY HERE PAY HERE AND LATER REALIZED AFTER TWO WEEKS OF HAVING THE CAR THAT HAS A RECALL FOR THE AIRBAG ON THE PASSENGER SIDE...BUT THE CAR WAS SOLD AS IS FROM AUTO SALES IN BUFORD GA

WHILE DRIVING THE CAR ON A COUNTY ROAD, WITH THE SPEED UNDER 40 MPH, AND FOLLOWING THE BEND IN THE ROAD TO LEAD TO GETTING ON THE HIGHWAY, THE CAR JERKED FORWARD AS IF I HIT SOMETHING. AS I CONTINUED TO DRIVE, THE CAR WAS MAKING LOUD CLINKING SOUNDS AND WAS JERKING IN MOTION. NO WARNING LIGHTS WENT ON. WHILE ATTEMPTING TO CONTINUE TO DRIVE, CLANGING NOISES COULD BE HEARD AND THE CAR CONTINUED TO JERK FORWARD. THE CAR WAS UNABLE TO BE DRIVEN. 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.

WHILE DRIVING STRAIGHT ON A HIGHWAY THE WATER PUMP BEARING FAILED CAUSING COOLANT TO LEAK AND MIX WITH THE ENGINE OIL. THE CAR IMMEDIATELY STARTED TO MAKE A RATTLE NOISE AND SMOKE OR STEAM CAME FROM UNDER THE HOOD. THE UNDERSIDE OF THE CAR WAS COVERED WITH COOLANT AND WHAT APPEARED TO BE OIL. THE CAR WAS NOT DRIVABLE AND HAD TO BE TOWED TO A MECHANIC. ONCE AT THE MECHANIC THE TOOK THE ENGINE OUT TO GET TO THE WATER PUMP, ONCE EVERYTHING WAS PUT BACK TOGETHER IT WAS FOUND THAT THE FAILURE ALSO CAUSED DAMAGE TO THE VVT ACTUATER AND ALTERNATOR. THE ENGINE IS COMPLETELY SHOT.

THE BRAKE PEDAL SEEMS HARD TOO STOP THE CAR WHEN IN MOTION ON PUBLIC STREETS, VEHICLE CONTINUES TOO ROLL UPON PUMPING BRAKES, HAVE TOO CONTINUOUSLY PUMP THE BRAKE HARD TOO STOP THE VEHICLE, HAD THE FRONT BRAKES REPLACED RECENTLY, AND BRAKE PEDAL IS STILL NOT FUNCTIONING CORRECTLY, POSSIBLY THE BRAKE BOOSTER.

I CAME OUTSIDE TO MY CAR ONE MORNING AND STARTED THE VEHICLE.. I NOTICED THE AIRBAG LIGHT WAS BLINKING, AND IT NEVER WAS BEFORE.. SO I SHUT THE VEHICLE OFF TO VISUALLY INSPECT IT.. WHAT I FOUND WAS THE PASSENGER CURTAIN AIRBAG HAD MALFUNCTIONED.. IT DIDN'T DEPLOY FULLY, BUT IT PUCKERED MY HEADLINER SO NOW IT'S JUST HANGING ON THE PASSENGER SIDE.. I INFORMED MAZDA OF THIS AND I WAS TOLD IT'S ONLY A RECALL ON PASSENGER AIRBAG SENSOR, BUT NO RECALLS FOR CURTAIN AIRBAGS.. WHAT CAN I DO

I WENT FROM HAVING BRAKES TO HAVING TO PUSH THE BRAKE TO THE FLOOR, WHICH STILL DID NOT STOP THE CAR, ALL IN THE SAME DAY. I WAS LUCKY NOT TO WRECK BUT COULD NOT STOP FOR STOP SIGNS OR STOP LIGHTS ALL WHILE MY 22 MONTH OLD WAS IN THE VEHICLE. SOMETHING IN THE BRAKE SYSTEM MESSED UP, AND IT STILL HAD A FULL THING OF BRAKE FLUID. I BELIEVE THAT IT IS THE BRAKE BOOSTER CAUSING THIS PROBLEM. *TR

SUDDENLY STARTS TO ACCELERATE WHILE AT A STOP LIGHT, STOP SIGN OR I AM LETTING A PERSON OUT AND STILL IN DRIVE AND MY FOOT IS ON THE BREAK. IT HAS DONE IT 4 TIME SINCE I GOT HER BOUGHT 02/03/2020 THE LAST WAS 06/06/2020. I HAVE TO PRESS DOWN ON THE BREAK VERY HARD TO KEEP IT FROM GOING FORWARD LASTS ONLY A SECOND OR TWO. *TR

BRAKES WHEN APPLIED WOULD SOMETIMES GO TO THE FLOOR BEFORE STOPPING. THE BRAKE BOOSTER HAS GONE BAD AND VERY DANGEROUS ALMOST CAUSING AN ACCIDENT. BRAKE PEDAL SOFT AND SOMETIMES WILL NOT STOP.

TL* THE CONTACT OWNS A 2011 MAZDA CX-9. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 10 MPH, BOTH FRONT AND REAR SIDE DRIVER AND PASSENGER SIDE CURTAIN AIRBAGS DEPLOYED INADVERTENTLY. DURING THE INCIDENT NO COLLISION HAD OCCURRED AND VEHICLE WAS NOT DRIVEN OVER A BUMP. THE DRIVER SUSTAINED NECK AND LEFT SHOULDER INJURIES AND SUFFERED HEADACHES SINCE THE INCIDENT. MEDICAL TREATMENT WAS REQUIRED. THE VEHICLE WAS TOWED TO THE LOCAL DEALER BROWN MAZDA OF CHANTILLY (4155 AUTO PARK SERVICE CHANTILLY, VA). THE CAUSE OF THE FAILURE WAS NOT DETERMINED. THE MANUFACTURER WAS ALSO NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 137,000.

BRAKES REALLY HARD TO PRESS. WIFE THOUGHT CAR WASN'T GOING TO STOP AND SHE WAS GOING TO REAR END CAR IN FRONT OF HER. SOMETIMES BRAKE PEDAL WOULD FEEL SPONGY. OVER LAST MONTH THERE WAS AN INTERMITTENT STRANGE NOISE SOMETIMES WHEN CAR WAS STARTED. MAZDA DEALERSHIP IDENTIFIED THE PROBLEM TO BE A DEFECTIVE BRAKE BOOSTER. I FOUND THAT NHTSA OPENED INVESTIGATION ON CX-9 BRAKE ISSUES PREVIOUSLY AND MAZDA IDENTIFIED PROBLEM TO BE BRAKE BOOSTER. MAZDA EXTENDED THE WARRANTY TO 7 YEARS OR 90,000 MILES AND NHTSA CLOSED INVESTIGATION. OUR BRAKE BOOSTER FAILED AT 9 YEARS WITH 79,388 MILES ON THE CAR. FROM WHAT I HAVE READ THE LIFE EXPECTANCY OF A BRAKE BOOSTER IS THE LIFE OF THE CAR. MAZDA NEVER INFORMED US ABOUT THIS POSSIBLE PROBLEM. OUR FAMILY COULD HAVE BEEN SERIOUSLY INJURED OR KILLED DUE TO THIS DEFECT. WHY DID THE NHTSA ACCEPT AN EXTENDED WARRANTY AS A SOLUTION?

TL* THE CONTACT OWNS A 2011 MAZDA CX9. THE CONTACT STATED THAT WHILE HIS WIFE WAS DRIVING APPROXIMATELY 13 MPH AND ATTEMPTING TO SLOW DOWN, THE BRAKE PEDAL WAS HARDER THAN USUAL TO DEPRESS. AS A RESULT, THE DRIVER REAR ENDED THE VEHICLE IN FRONT CAUSING A FIVE VEHICLE COLLISION AT A TRAFFIC LIGHT. NONE OF THE FRONTAL AIR BAGS DEPLOYED. THE POLICE WERE PRESENT AND A POLICE REPORT WAS FILED. THERE WERE NO INJURIES REPORTED. THE VEHICLE WAS TOWED TO AN IMPOUND LOT WHERE THE INSURANCE COMPANY WAS SCHEDULED TO HAVE AN INSPECTOR INSPECT THE VEHICLE. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR A DIAGNOSTIC. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE CONTACT REFERENCED NHTSA ACTION NUMBER: PE14005 (SERVICE BRAKES, HYDRAULIC). THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 86,000.

Crash

THE TRANSFER CASE IN OUR 2011 MAZDA CX-9 FAILED AT 130,000 MILES. I UNDERSTAND THAT MAZDA KNOW ABOUT A DEFECT AS TO THE PROXIMITY OF THE TRANSFER CASE TO THE EXHAUST. THE HEATED TRANSFER CASE LUBRICANT BECOME SLUDGE-LIKE AND CAUSES THE CASE TO FAIL ALSO AFFECTING THE TRANSMISSION SPLINES. THE HEATED LUBRICANT ESCAPED AND DRIPS ON THE EXHAUST AND FILLS THE VEHICLE WITH A TOXIC SMELLING GAS AND APPARENTLY CAN LIGHT ON FIRE. THE TRANSFER CASE FAILED WHILE DRIVING MAKING GETTING OUT OF TRAFFIC DIFFICULT. MAZDA ISSUED A BULLETIN IN 2014 EXTENDING THE WARRANTY TO 7 YEARS OR 90,000 MILES BUT DIDN'T INFORM ANY OF THE CUSTOMERS OF THIS PROBLEM. THERE IS NO SERVICE SCHEDULE FOR THE TRANSFER CASE AS RECOMMENDED BY MAZDA. OR ANY WAY I UNDERSTAND TO CHANGE THE LUBRICANT IN THE TRANSFER CASE. WITHOUT INFORMING US OF THE ISSUE OR HAVING RECOMMENDED ANY PREVENTATIVE MAINTENANCE MAZA CAUSED A VERY DANGEROUS SITUATION FOR MY FAMILY. I HAVE CONTACTED MAZDA USA AND THEY HAVE BEEN UNHELPFUL.

BRAKE BOOSTER IS LEAKING. TAKES LONGER TO STOP. CALLED MAZDA AND REPORTED ISSUE.

BRAKE PEDAL IS VERY HARD AND VEHICLE IS NOT STOPPING WELL ALMOST CAUSING AN ACCIDENT

OUR VEHICLE HAS LOST BRAKING POWER AND IS UNSAFE TO DRIVE ANY DISTANCE NOW. IT IS VERY DIFFICULT TO GET THE VEHICLE TO STOP AND KEEP IT STOPPED ONCE IT HAS STOPPED MOVING WITHOUT PUTTING IT IN PARK. I HAVE BEEN ADVISED THIS IS IN RELATION TO MAZDA SSP 93. MAZDA HAS ADVISED THAT IS IT MY RESPONSIBILITY TO HAVE THIS VEHICLE TOWED TO THE NEAREST DEALERSHIP, PAY FOR REPAIR LABOR, AND PAY FOR A RENTAL CAR WHILE REPAIRS ARE BEING MADE. I AM IN COMPLETE DISBELIEF THAT A KNOWN MANUFACTURER'S DEFECT RELATED TO BRAKING AND GENERAL SAFETY OF EVERYONE ON THE ROAD WAS NOT IMMEDIATELY ISSUED AS A RECALL. WE WERE PROVIDED ZERO NOTICE THAT THERE WAS EVEN POTENTIAL FOR BRAKE FAILURE.

THE A/C EVAPORATOR TANK CONDENSATION DRAIN CLOGS. OURS HAS CLOGGED TWICE AND THE FIRST TIME THE WATER IN THE TANK WOULD SLOSH AROUND AND HEAR IT WHEN MAKING A LEFT TURN. EVENTUALLY IT RUINED THE BLOWER MOTOR TO THE A/C, WHICH HAD TO BE REPLACED. NOW 19 MONTHS LATER, WE HEARD THE WATER AGAIN AND TOOK IT IN RIGHT AWAY AND IT WAS CLOGGED AGAIN AND THE BLOWER MOTOR HAS TO BE REPLACED AGAIN. THIS IS A DESIGN DEFECT. THERE SHOULD BE A BETTER DRAIN SYSTEM. CLEARLY THIS IS AN ISSUE WITH THE MAZDA CX-9 MODEL IN SEVERAL YEARS BECAUSE THERE ARE VIDEOS OF HOW TO UNCLOG THE A/C DRAIN.

TL* THE CONTACT OWNS A 2011 MAZDA CX-9. WHILE DRIVING 40 MPH, THE CONTACT HEARD AN ABNORMAL NOISE AND NOTICED WATER DRIPPING FROM THE SUN ROOF INTO THE INTERIOR OF THE VEHICLE ONTO THE DASHBOARD. THE CONTACT STATED THAT THE LEAK CAUSED AN ELECTRICAL SHOCK TO THE BLOWER MOTOR OF THE AIR CONDITIONER. THE VEHICLE WAS TAKEN TO LOU BACHRODT MAZDA COCONUT CREEK (LOCATED AT 5400 FL-7, COCONUT CREEK, FL 33073, (954) 247-5000) WHERE IT WAS DIAGNOSED THAT THE AIR CONDITIONER BLOWER MOTOR NEEDED TO BE REPLACED AND THE SUN ROOF NEEDED TO BE DE-CLOGGED. THE VEHICLE WAS REPAIRED, BUT CONTINUED TO EXPERIENCE THE FAILURE. THE MANUFACTURER WAS NOTIFIED. THE FAILURE MILEAGE WAS 102,000.

WHEN TRYING TO STOP AT AN INTERSECTION, THE BRAKES DID NOT RESPOND AS USUAL. EVEN WITH PRESSING THE BRAKE PEDAL AS HARD AS I COULD, THE STOPPING DISTANCE INCREASED BY AT LEAST 30 FEET WHICH PLACED ME IN THE MIDDLE OF THE INTERSECTION. THIS IS WORSE IN HOT CONDITIONS. THERE IS ALSO A HISSING NOISE WHEN THE BRAKE PEDAL IS DEPRESSED. THIS CONTINUES TO HAPPEN AND DOES NOT FEEL SAFE TO DRIVE. A MECHANIC SAID IT MAY BE THE POWER BRAKE BOOSTER. I NOTICED THAT THIS WAS INVESTIGATED, MAZDA ISSUED A SPECIAL SERVICE PROGRAM WHICH ENDED IN 2015. THE LETTER ISSUED AT THAT TIME SAID IT WAS NOT NECESSARY TO TAKE ACTION UNLESS THERE WAS A PROBLEM AT THAT TIME. MAZDA SHOULD EXTEND THE SERVICE PROGRAM BECAUSE THIS IS CLEARLY A SAFETY ISSUE.

I BOUGHT THE CAR UNDER WARRANTY UP TO 90,000 MILES, WHEN I BOUGHT TRUCK 2015 AND TOOK IN WE TOLD DEALER THAT THE WAS CAR LEAKING BLACK SUBSTANCE THEY SAID THEY DID NOT SEE ANYTHING . WE TOOK IT FOR A RECALL AND TOLD THE DEALER SAME THING THIS TIME OFF AND ON IT WOULD SMELL LIKE BURN RUBBER BY THIS TIME WARRANTY WAS NOT COVERED. THE ISSUE WAS NOT DIAGNOSED UNTIL WE TOOK IT TO FOR AN OIL CHANGE AND ROUTINE INSPECTION AT 108 SOMETHING MILES THE SMELL OF BURNT RUBBER IS MORE PERSISTENT THE MECHANIC TOLD US THERE IS A LEAK IT LOOKS LIKE TRANSMISSION OIL AND IT IS DRIPPING TO AXLE.WE TOOK IN TRUCK TO FIRST MECHANIC TO GET A QUOTE HE COULD ONLY GET PART AT THE DEALER THEY SAID THAT THE WHOLE POWER TRANSFER CASE WOULD NEED TO BE CHANGE NOT JUST THE SEALS. TOOK IT IN FOR SECOND OPINION THAT MECHANIC SAID THAT THOSE PARTICULAR MODELS AND YEAR HAVE BEEN TAKEN IN FOR SAME ISSUE AND END UP HAVING TO CHANGE POWER TRANSFER CASE BECAUSE IT WAS POORLY MANUFACTURED THAT THE EXHAUST IS TO CLOSE IT MELTS RUBBERS AND LEAKS TRANSMISSION OIL THEREFORE CHANGING SEALS WILL NOT CORRECT THE PROBLEM THE WHOLE THING NEEDS TO BE CHANGE. I HAVE 3 SMALL CHILDREN AND SMELL OF RUBBER IS CONCERNING IT UPSETTING THAT THERE IS MULTIPLE CARS FROM YEAR 2011 TO 2017 WITH THESE ISSUE'S AND THERE HAS NOT BEEN A RECALL DOES A CAR NEED TO CATCH ON FIRE WITH KIDS IN IT. THIS IS A MANUFACTURING ISSUE AND SHOULD BE INVESTIGATED.

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

TL* THE CONTACT OWNS A 2011 MAZDA CX-9. THE CONTACT STATED THAT THERE WAS AN INTERMITTENT FAILURE WITH THE BRAKE SYSTEM FAILING TO FUNCTION PROPERLY AS THE CONTACT HAD TO PRESS THE BRAKE PEDAL, RELEASE THE BRAKE PEDAL AND APPLY FORCE TO STOP THE VEHICLE. THE FAILURE HAPPENED MORE THAN ONCE TO THE POINT OF IT BEING A RISK THAT MAY RESULT IN A CRASH. IN ADDITION, THE VEHICLE STALLED. THE VEHICLE WAS UNSAFE TO DRIVE, PARKED AT THE OWNER'S RESIDENCE AND MAY NEED TO BE TOWED FOR REPAIRS. THE DEALER YOUNG MAZDA (191 COMMERCE PARK DR, EASTON, PA 18045, (610) 991-9100) WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED. THE VEHICLE WAS NOT INCLUDED IN NHTSA ACTION NUMBER: PE14005 (SERVICE BRAKES, HYDRAULIC). THE MANUFACTURER WAS NOTIFIED OF THE FAILURE TO DETERMINE IF THEY HAD A TECHNICAL GUIDELINE TO REPAIR THE VEHICLE. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS NOT AVAILABLE.

BRAKE BOOSTER FAILURE

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.

FAILURE OF THE POWER TRANSFER CASE / POWER TRANSFER UNIT ("PTU"). THE DEFECT WAS DISCOVERED WHEN A BLACK OIL LIKE SUBSTANCE WAS FOUND UNDER THE ENGINE COMPARTMENT OF THE VEHICLE IN THE GARAGE. VEHICLE WAS TAKEN TO A MAZDA DEALERSHIP FOR INSPECTION AND DIAGNOSIS. OEM ADVISED THAT IT WAS A DEFECTIVE PTU. OEM STATES THAT IT IS A KNOWN DEFECT. INTERNET RESEARCH REVEALS THE BREADTH OF THE DEFECT. OEM STATES THAT LIMITED WARRANTY WAS EXTENDED TO 7 YEARS AND 100,000 MILES. SUBJECT VEHICLE HAS 71,000 MILES, BUT IS A FEW MONTHS OUTSIDE EXTENDED WARRANTY. OEM NEVER SENT NOTICE TO CONSUMERS ADVISING OF THE DEFECT. OEM NEVER ISSUED A RECALL FOR THE KNOWN DEFECT. OEM NEVER SENT NOTICE TO CONSUMERS ADVISING OF THE WARRANTY EXTENSION. OEM REFUSES TO COVER THE DEFECT UNDER WARRANTY. CONSUMER HAS PROMPTLY REMEDIATED ALL PRIOR KNOWN RECALLS DIRECTLY WITH OEM UPON RECEIPT OF NOTICE.

MAZDA CX-9 2011 HAS UN-DETECTED WATER PUMP LEAKS WHICH CAUSE TO ENGINE OVERHEAT AND EVENTUAL ENGINE DEATH. MAZDA CORPORATE IS UNWILLING TO CO-OPERATE. CAR SUDDENLY CAME TO A HALT SHOWING ENGINE LIGHT ON..AND I HAD TO REPLACE THE BRAKE BOOSTER ALSO BECAUSE WHEN I WAS DRIVING THE VEHICLE IT TURN OFF ON ME EVERYWHERE AND I HAD TO PAY OUT OF MY POCKET AND IM STILL PAYING FOR THIS VEHICLE RIGHT NOW MY VEHICLE IS IN A GARAGE BECAUSE IS NOT DRIVABLE

DIFFICULTY PUSHING THE BRAKE PEDALS AND ACHIEVING A FULL STOP. SOMETIMES CAR WOULD INCH FORWARD WHEN BRAKE APPLIED. SOMETIMES HEARING A HISSING NOISE WHEN TRYING TO APPLY THE BRAKES. THE NOISE SEEMED TO COME FROM THE AREA OF THE BRAKE PEDAL. OVERALL, BRAKES DID NOT APPEAR TO BE WORKING AS INTENDED. PRIMARILY EXPERIENCED AT LOWER SPEEDS. HAS HAPPENED REPEATEDLY OVER A FEW WEEKS.

I STARTED NOTICING IT WAS TAKING A LONG DISTANCE FOR MY VEHICLE TO COME TO A STOP. I TOOK IT TO MY MECHANIC. WE TOOK IT FOR A TEST DRIVE AND HE CONFIRMED THERE WAS A PROBLEM WITH THE POWER BRAKE BOOSTER. WHEN HE WAS DRIVING, IF HE PRESSED ON THE BRAKE PEDAL HARD, HE COULD MAKE THE CAR HAVE A LONG "BEEP" SOUND. OTHERWISE, HE, TOO, NOTICED THE LONG DISTANCE REQUIRED FOR THE CAR TO STOP.

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.
