2012 Mazda CX-9 brake problems

SERVICE BRAKES

I was driving normally when I started sowing down and noticed the brakes were harder to push. I finally stopped just before almost rear-ending a vehicle in front of me. It turns out the brake booster, a known problem that was not communicated to me a few years ago, failed and makes braking the vehicle harder, increases distance, and makes the vehicle unsafe to drive. The problem has been reproduced via a diagnostic test at Mazda of Gladstone dealership on 9/27/23. The dealership has been the only people who have inspected the issue. There were no warning signs, no warning lights, nothing. It was scary because I didn't think my vehicle was going to stop. It's completely dangerous. I have not gotten the vehicle repaired yet because I believe Mazda holds responsibility as this has been a known issue with their cars.

On August 14, 2020, the brake booster along with the master cylinder failed, resulting in very dangerous and frightening driving conditions, and the parts were replaced with Mazda original parts. This was an ongoing issue with the Mazda CX-9’s. I reported it to the NHTSA, complaint number 11480067. On January 4, 2023, the brake master cylinder and booster failed again resulting again in very dangerous and frightening driving conditions. The car was driven only 25,383 miles before the brakes failed the second time. The Mazda parts were defective and continue to be so after many years with no effort by Mazda to improve these parts. Attached are the repair invoices for both incidents. I have tried contacting Mazda and they refuse to address the issue.

The brakes suddenly became very difficult to press as if I did not have power brakes. No warning lights came on and it became very difficult to stop the car. Then if I had to break suddenly and hard it would stall. I brought it to the repair shop and the brake booster was defective. The brake booster along with the master cylinder had to be replaced. It was a very dangerous and frightening experience the brakes suddenly difficult to use. I contacted Mazda customer service and they did not care. I then tried to escalate the issue over the last two years but it was impossible to contact anyone and all emails came back undeliverable. I just recently learned that I can report this danger to the NHTSA.

This is relating to NHTSA Investigation PE 14-005. Although this car is a 2012 Mazda CX9, my wife driving the car had the same issue where she heard a hissing noise and the brakes were very difficult for her to depress or to stop. A brake issue is a major defect where the NHTSA should have initiated a recall in accordance with 49 U.S.C. 30118-30120, which required notification of all owners. Why the NHTSA allowed Mazda to only issue a 'Special Extended Warranty' is beyond me, and smells of a back door deal. Nonetheless, I was unaware of this issue with the Mazda CX9's as I was never notified. My wife drove the vehicle home and I purchased the replacement parts at my own expense. This should be a full recall and should be reopened as your current investigation PE 14-005 only included years 2010-2011, and did *not* include the 2012 model year.

I WAS ON THE INTERSTATE (DRIVING 60+MPH) AND THE CAR IN FRONT OF ME SLAMMED ON THEIR BRAKES FOR AN UNKNOWN REASON. I TRIED TO USE MY BRAKES BUT THEY WERE ROCK HARD AND THE PEDAL WOULDN'T DEPRESS. I WAS FORCED TO SWERVE TO THE RIGHT, STILL HAVING NO BRAKES, AND BARELY MADE IT OVER 3 LANES TO THE SHOULDER OF THE ROAD. IN DOING SO, I CAUSED TOTAL CHAOS AROUND ME, CAUSED A TRACTOR TRAILER TO START TO JACKKNIFE, WHICH CAUSED A CHAIN REACTION BEHIND HIM. IT WAS A TOTAL MIRACLE THAT NO ACCIDENTS WERE CAUSED AND NO ONE WAS KILLED. I CALLED MY MECHANIC FROM THE SIDE OF THE ROAD, HYSTERICAL. HE LOOKED IN HIS DATABASE AND FOUND THAT MAZDA HAD KNOWN ISSUES WITH THEIR POWER BRAKE BOOSTER. I SUBSEQUENTLY FOUND A LETTER FROM MAZDA INSTRUCTING OWNERS "IF YOUR VEHICLE IS FUNCTIONING PROPERLY, THERE IS NO NEED TO CONTACT YOUR DEALER." ARE YOU KIDDING ME???? MY BRAKES WERE FINE UNTIL THEY WEREN'T, THEN I NARROWLY AVOIDED BEING KILLED OR CAUSING THE DEATH OF ANOTHER BECAUSE APPARENTLY MAZDA'S BODY COUNT WASN'T HIGH ENOUGH TO ISSUE A RECALL.

BRAKE PEDAL HAS BECOME HARDER THAN USUAL TO DEPRESS AND THE CAR DOES NOT START STOPPING UNTIL THE BRAKE PEDAL IS DEPRESSED HARDER AND FURTHER DOWN. ALSO THERE IS A HISSING NOISE ONCE THE CAR STOPS AND THE BRAKE PEDAL GOES FURTHER TO THE FLOORBOARD. ONCE STOPPED AND SITTING THE CAR WILL LURCH AS IF IT HAS BEEN HIT IN THE REAR END.

I WAS DRIVING HOME WITH THE FAMILY AFTER VIEWING SOME HOUSE. EVERY TIME I WOULD STEP ON THE BRAKE PEDAL I WOULD HEAR A HISSING FROM THE BRAKE. BEEN HAPPENING FOR ABOUT A MONTH NOW BUT, WITH THE PANDEMIC GOING ON I JUST DON'T HAVE TIME TO DIAGNOSE THE PROBLEM. WHEN I PRESS ON THE BRAKE IT WOULD STOP LIKE NORMAL WITH AIR HISSING. THE NEXT DAY THE BRAKE PEDAL WOULD FEEL VERY HARD TO PRESS DOWN. LIKE AS IF YOU BEEN PUMPING YOUR BRAKE WHEN THE CAR OFF AND WHEN YOU TURN YOUR CAR ON THE PRESSURE WOULD BE RELEASED. NOT TODAY, IT STAYED HARD AND HARD TO STOP. I HAD TO PRESS THE BRAKE VERY HARD AS IF PRESSING THE BRAKE PEDAL ALL THE WAY DOWN TO THE FLOOR TO MAKE THE CAR STOP. JUST STOPPING AT A RED LIGHT, STOP SIGN, OFF THE HIGHWAY, AND TRAFFIC WAS A CHALLENGE. I'LL EVENTUALLY STOP BUT IN THE MIDDLE OF A INTERSECTION OR IN THE BACK OF A CAR. IF I HAD TO BRAKE BECAUSE SOMEONE TURNED IN FRONT OF ME, I WOULD OF JUST HIT THEM FULL SPEED BECAUSE MY BRAKE BOOSTER FAILURE TO PRODUCE ENOUGH PRESSURE TO ENGAGE MY BRAKES TO STOP. THE DAY THE BRAKE BOOSTER HAPPEN TO FAILURE COMPLETELY IS WHEN WE HAD A FAMILY TRIP DOWN TO THE WISCONSIN DELLS OVER THE JULY 4TH WEEKEND. SINCE BRAKE BOOSTER WASN'T A RECALL BUT AN EXTENDED WARRANTY AND ENDED MARCH 2015 OR 90,000 MILES. MAZADA WOULD CHARGE ME FULL PRICE TO GET IT FIXED. I WOULD NOT FELL SAFE DRIVING IT TO THE DEALER AND MAZADA DOESNT COVER TOWING UNLESS ITS WITHIN 3 YEARS. SO THEY'LL TOW ANYTHING IN THE 2017 AND NEWER. 2012 MAZADA CX-9 WITH 112,500. OWNED IT FOR EXACTLY 3 TO DATED

PURCHASED FROM A CERTIFIED PRE-OWNED MAZDA DEALER....I EXPERIENCED, WITH NO WARNING, MY BRAKES BECOME HARD TO PRESS. IT HAPPENS IN REVERSE, COMING OFF CRUISE, SLOW/FAST SPEED, ETC. I HAVE TO USE AN EXTRAORDINARY AMOUNT OF EFFORT TO PRESS THE BRAKES AND BRING THE CAR TO A STOP. IF SOMEONE PULLS OUT IN FRONT OF ME, THERE IS NO GUARANTEE I WOULD BE ABLE TO OPERATE THE BRAKES QUICKLY ENOUGH TO AVOID AN ACCIDENT. I HAVE CHILDREN I TRANSPORT AND IT IS CONCERNING FOR ME AS A MOM ESPECIALLY. A FEW TIMES THE PEDAL WILL 'RELEASE' AND OPERATE NORMALLY AFTER THE EXTRA PRESSURE IS APPLIED WHICH CAUSES THE CAR TO JERK TO A STOP BECAUSE THE BRAKES WERE BEING PRESSED VERY HARD. MOST TIMES, EXTRA PRESSURE IS REQUIRED THE ENTIRE TIME. THIS IS A MAJOR SAFETY CONCERN AND AN ISSUE I AM AWARE IS COMMON IN THIS MODEL. MAZDA EXTENDED THIS WARRANTY TO 90K AND 7 YEARS BACK IN 2015; HOWEVER, THIS DOES NOT COVER USED CAR PURCHASERS. THE ISSUE WAS NOT DISCLOSED TO ME IN MY PURCHASE DATE OF 12/12/2016. HAD I KNOWN THIS MAJOR COMPONENT COULD FAIL, I WOULD HAVE MADE A MORE EDUCATED DECISION ON WHETHER TO PURCHASE OR REQUEST THE FAULTY SYSTEM BE CORRECTED.

I AM NOW EXPERIENCING WHAT MAZDA MAILED OWNERS PREVIOUSLY (SEE ATTACHED SSP93 OWNERS NOTICE) REGARDING "POWER BRAKE UNIT WARRANTY EXTENSION PROGRAM SSP 93 2007-2013 MAZDA CX-9". I STRONGLY BELIEVE THAT THIS IS A SAFETY ISSUE SINCE I FIND MYSELF RUNNING STOP SIGNS WHEN I TRY TO STOP THE VEHICLE AT AN INTERSECTION. I KNOW THAT MAZDA EXTENDED THE WARRANTY TO 7 YEARS ON IT'S SSP93 BULLETIN. BUT WHAT HAPPENS TO OWNERS LIKE MYSELF WHO DO NOT FALL WITHIN THAT TIME-FRAME AND ARE NOW EXPERIENCING THIS SAFETY ISSUE? IT IS UNCONSCIONABLE, THAT SINCE MAZDA HAS ACKNOWLEDGED THIS PROBLEM, THAT THE OWNER LIKE MYSELF GETS STUCK WITH THIS SAFETY PROBLEM CONCERNING FAILURE OF THE BRAKING SYSTEM ON THE CX-9. PLEASE ADVISE. THANKS.

BRAKE BOOSTER FAILED. THIS IS A KNOWN ISSUE TO MAZDA. MAZDA SAID TO BRING INTO DEALER FOR ASSESSMENT AND CONSIDERATION FOR GOODWILL WARRANTY REPLACEMENT. DEALER DETERMINED BRAKE BOOSTER FAILED AND MAZDA THEN DENIED GOODWILL CLAIM. I PAID DEALER TO FIX THE ISSUE. THIS IS A MAJOR SAFETY ISSUE AND SHOULD HAVE BEEN RECALLED, NOT GRANTED AN EXTENDED WARRANTY.

SO DISAPPOINTED IN NHTSA FOR NOT REQUIRING MAZDA TO RECALL THE BRAKE BOOSTER FAILURE! NHTSA'S INVESTIGATION INTO THE BRAKE BOOSTER FAILURE WAS CLOSED WHEN MAZDA AGREED TO AN EXTENDED WARRANTY FOR THIS MANUFACTURING SAFETY DEFECT. HAD THE NHTSA PUSHED FOR A RECALL NOTICE, WE WOULD HAVE BEEN ALERTED TO THIS SAFETY DEFECT AND COULD HAVE HAD IT REPAIRED (IT IS KNOWN TO FAIL AROUND 62,000 MILES). WE CONTACTED MAZDA TODAY ABOUT THE WARRANTY ONLY TO BE TOLD OUR VEHICLE WARRANTY EXPIRED LESS THAN 3 MONTHS AGO, RESULTING IN MAZDA'S REFUSAL TO COVER A KNOWN SAFETY DEFECT. MAZDA'S LACK OF COMMITMENT TO RESOLVING THIS SAFETY ISSUE IS SHOCKING. NHTSA'S ACCEPTANCE OF MAZDA EXTENDING ITS WARRANTY FOR THIS KNOWN SAFETY ISSUE IS DISHEARTENING AS WELL. A MANUFACTURING DEFECT IS A MANUFACTURING DEFECT; THE PROBLEM SHOULD HAVE BEEN ADDRESSED WHEN IT FAILED OR, AT THE VERY LEAST, RECALLED AND REPLACED. A TIME LIMIT SHOULD NOT HAVE BEEN AN OPTION FOR A SAFETY ISSUE (OR AN OUT FOR MAZDA). PERHAPS IT IS TIME FOR NHTSA TO REOPEN ITS INVESTIGATION TO PROTECT THE CONSUMERS AGAINST A KNOWN SAFETY DEFECT. MAZDA CERTAINLY DOESN'T BACK IT'S PRODUCT WHEN IT COMES TO SAFETY ISSUES!

APPLYING BRAKES FOR 1-2 SECONDS RESULTED IN NO IMMEDIATE STOPPING, ONLY RESISTANCE FROM THE PEDAL. AFTER 1-2 SECONDS, THE BRAKES WERE AGGRESSIVLY APPLIED. THIS RESULTED IN "RUNNING A STOP SIGN" AND STOPPING THE IN MIDDLE OF AN INTERSECTION. THIS OCCURRED ON A CITY STREET MULTIPLE TIMES BEFORE GETTING THE CAR TO A REPAIR SHOP. ON HIGHWAYS, BRAKING HAD TO BEGIN WELL IN ADVANCE TO AVOID POSSIBLE CRASHES. WE HAD TO HAVE THE MASTER CYLINDER AND BRAKE BOOSTER REPLACED. THE VEHICLE HAS 55K MILE ON IT.
