CLUTCH FAILED AT 19.5K MILES. IVE ONLY HAD HER SINCE NOVEMBER, AND WITH THE WAY I DRIVE THERES NO WAY IN HELL THE CLUTCH SHOULD GO OUT THIS SOON... NOW AS TO EXPLAIN AS TO WHAT HAPPENED, I WAS DRIVING ON THE HIGHWAY WHEN MY ENGINE STARTED REVING A BIT ODDLY WHEN I BARELY PRESSED ON THE GAS PEDAL. IT WENT FROM THE NORMAL 2900 RPM IN 6TH GEAR AT ABOUT 65 MPH AND SHOT UP TO 3500 WAY TO QUICKLY THEN DROPPED BACK TO 2900 AND SLOWLY ROSE HOW IT SHOULDVE TO GET ME TO 70MPH...IT CONTINUED DOING THIS WHEN I GOT OFF THE HIGHWAY FOR ABOUT 15 MINUTES, GROWING STEADILY WORSE UNTIL I WAS UNABLE TO GET INTO ANY GEAR AT ALL. THERE WAS NEVER A SMELL OF CLUTCH INSIDE THE CAR THE ENTIRE TIME, NO ODD NOISES, NO GRINDING, AND THE CLUTCH WAS ABOUT HALF AS STIFF AS IT NORMALLY WAS. SO I CALLED DEALER, THEY TOWED MY CAR(COURSE IT TOOK FOREVER BECAUSE THEY SENT THE TRUCK TO THE WRONG LOCATION HAHA). IT TOOK 2 DAYS BEFORE THEY EVEN GOT TO GLANCE AT THE CAR TO SEE WHAT NEEDED TO BE DONE(NOT TAKE APART MIND U, JUST LOOKED), AND SAID THE CLUTCH WAS "SMOKED" NO OTHER SPECIFICS BUT WANTED ME TO AUTHORIZE THEM FOR 525 WORTH OF LABOR PLUS PARTS -_-. SO NOW IM STUCK FIGHTING THEM TO REPAIR THIS UNDER WARRANTY(I KNOW THERES USUALLY NOT A WARRANTY UNLESS MANUFACTURERS DEFECT..BUT THIS IS DEFINITELY DEFECTIVE). INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) *TT

THERE HAS NOT BEEN A FAILURE TO DATE, HOWEVER, ADDING MY VEHICLE TO THE OTHER MAZDA3'S IN THE DATA BASE WHERE THE DESIGN OF THE VEHICLE IS CREATING UNEVEN TIRE WEAR. AS I HAVE READ IN NO LESS THAN 5 BLOGS, THE MANUFACTURER INTENTIONALLY CAMBERS THE REAR TIRES TO INCREASE THE PERFORMANCE AND HANDLING AND UPON NORMAL ROTATION OF THE TIRES, A "BUMPING" NOISE CAN BE HEARD AND FELT. THE TIRE MANUFACTURER WILL DO NOTHING AND STATES IS A DESIGN ISSUE AND MAZDA STATES I MUST DEAL WITH THE TIRE MANUFACTURER. THIS UNEVEN TIRE WEAR AND VIBRATION COULD LEAD TO ADDITIONAL TIRE WEAR AS NOTED BY OTHER OWNERS. AT 11,000 MILES, I SHOULD NOT BE FACED WITH REPLACING THE TIRES.

I HAVE NOW HAD "THREE" VALVE STEMS THAT HAVE BROKEN; WITH SLOW LEAKS AND FLAT TIRES. THE LAST ONE LEAVING ME STRANDED FOR 2 HRS UNTIL HELP ARRIVED. THIS ALSO HAPPENED 2 DAYS AFTER I HAD MY CAR IN FOR SERVICE FOR ANOTHER TIRE WITH A "VALVE" STEM REPLACEMENT--COSTING ME $198.00. ALSO TOLD THERE IS NO RECALL AND IT APPEARS MAZDA HAVING PROBLEMS NOW WITH THIS FOR A FEW YEARS. ALSO THOUGHT IT FUNNY THAT WHEN DEALERSHIP COMPLETING MY PAPERS THEY COMMENTED THAT THEY JUST COMPLETED EXACT SAME PAPERS FOR CAR BEFORE MINE !!!! I AM A CAUTIOUS DRIVER AND I KNOW MY WHEEL/TIRES WHERE NOT DAMAGED AND THAT WAS THE CAUSE OF THE VALVE STEM. I NOW HAVE 3 NEW VALVES STEMS THRU MY COST ---JUST WAITING FOR LAST ONE TO GO AND THEN WILL SEE HOW LONG THE "NEWER" ONES LAST. HAVE A FEELING THIS WILL BE AN ONGOING PROBLEM. AT LEAST DEALERSHIP CHANGED THE ONE TODAY AS A GOOD WILL FREE OF CHARGE. *TR

I OWN A 2010 MAZDA SPEED 3. PURCHASED JUST OVER A YEAR AGO. I HAVE A VALVE STEM THAT HAS BROKEN, WHICH RELEASED PRESSURE. THE VALVE STEMS USED ON THE VEHICLE ARE INCORPORATED INTO TIRE PRESSURE MONITORING SYSTEM (TMPS), AND THE DEALER REQUIRES THAT BOTH ITEMS BE REPLACED FOR $125. AFTERMARKET COMPANIES, SUCH AS DORMAN OFFER REPLACEMENTS THAT ARE MODULAR, AND ALLOW THE CONSUMER TO REPLACE JUST THE STEM, IF BROKEN. THE FACTORY, CONVENIENTLY DOES NOT OFFER THEM COMPONENT INDIVIDUALLY. BY THE LOOKS OF ONLINE FORUMS, THIS IS A PROBLEM THAT HAS BEEN AROUND FOR A COUPLE OF YEARS. I HAVE OWNED VEHICLES FOR 30 YEARS NOW, AND I HAVE NEVER ENCOUNTERED A BROKEN VALVE STEM LIKE THIS. THERE IS NO TRAUMA TO THE WHEEL ITSELF THAT WOULD EXPLAIN A BUSTED STEM THAT DOES NOT PROTRUDE BEYOND THE RIMS OUTER EDGE. I BELIEVE THAT THIS DANGEROUS PROBLEM COULD BE ELIMINATED IF MAZDA WERE TO REDESIGN THE THREADED PORTION OF THE STEM TO BE THICKER. THE ALUMINUM STEMS ARE MACHINED SO THINLY, THAT THEY FAIL, OR ARE EASILY DAMAGED WHILE PERFORMING BASIC MAINTENANCE. THE MAZDA DEALER DOES NOT FEEL THAT THE PARTS ARE FAULTY, AND THEY REFUSE TO COVER THIS UNDER WARRANTY. THE SERVICE MANAGER SAYS THEY HAVE NEVER HEARD OF THIS BROKEN STEM PROBLEM. I FIND THAT EXTREMELY HARD TO BELIEVE. RESOLUTION: I NEED TO GET MY SPARE TIRE OFF THE CAR, SO I WILL BE DROPPING THE WHEEL OFF AT A TIRE SHOP TO REPLACE THE UNIT WITH A STANDARD METAL STEM UNTIL I DECIDE WHAT ROUTE TO TAKE. MY RESEARCH LEADS ME TO BELIEVE THAT THIS WILL NOT BE THE LAST PROBLEM I HAVE LIKE THIS, UNTIL I GET THE DANGEROUS FACTORY ONES OFF OF MY VEHICLE. *TR

I TOOK IT INTO THE MAZDA DEALERSHIP IN ALEXANDRIA VIRGINIA (BROWNS MAZDA ON ROUTE 1) AND ASKED THEM TO LOOK AT IT. THEY DETERMINED THAT WELDING ON MY SEAT BOTTOM HAD COME UNDONE AND NEEDED TO BE REPLACED. MY CAR'S WARRANTY IS FOR 3 YEARS/36 THOUSAND MILES AND AT THE TIME OF THE INCIDENT MY CAR HAD 45 THOUSAND MILES. MAZDA DECLINED TO FIX THE SEAT AND STATED THAT I AM RESPONSIBLE FOR THE REPAIRS. MY CONTENTION IS THAT THE DRIVERS SEAT IS A SAFETY ISSUE AND IF INVOLVED IN A COLLISION THE SEAT MAY DISLODGE AND CAUSE ME MORE BODILY INJURY THAN IF THE SEAT WERE PROPERLY ANCHORED. I HAVE CONTACTED MAZDA'S CUSTOMER CARE LINE AND ALSO E-MAILED THEM AND ON BOTH OCCASIONS THEY HAVE IMMEDIATELY DISMISSED MY CLAIM STATING THAT MY VEHICLE IS OUT OF WARRANTY AND THE REPAIRS ARE MY RESPONSIBILITY.

1EA21002 · Desiccated Air Bag Inflator Rupture
Opened Sep 17, 2021 · No close date supplied
Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
