I WAS DRIVING IN CITY IN THE EVENING TEMP. ABOUT 65-70 F,DRY AND SMOOTH ROAD(MY DAILY ROUTE TO WORK) IN STEADY SPEED OF I WOULD SAY 45 MPH, TRYING TO CHANGE LANE MY CAR TRACTION LIGHT WENT ON AND ENGINE LIGHT AND AT LIGHT BELOW MY GEAR SCREEN, MY CAR LOCKED MY TRANSMISSION,CAR WAS IN DRIVE MODE SO I PUT ON MANUAL TO TRY CHANGE GEAR MANUALLY BUT DID NOT CHANGE GEAR, I WAS STUCK ON ONE GEAR AND I COULD NOT SLOW DOWN BECAUSE I WOULD LOOSE MY RPM MIDDLE OF THE ROAD, I DROVE ABOUT 2 MILE TILL I HAD SAFE PLACE TO STOP, PULLED OVER TURN OFF THE CAR AND WAIT FOR FEW MINUTES,THEN TURN ENGINE BACK ON,TRACTION LIGHT WAS OFF SO AS THE AT LIGHT BUT ENGINE LIGHT WAS STILL ON,CAR WAS BEHAVING NORMAL AND I COULD DRIVE IT HOME, NEXT DAY I TOOK IT TO DEALER I TURNED IT OFF FOR WAITING TO CHECK-IN MY CAR WHEN THE DEALER SERVICE PERSONAL TURNED IT ON AS SHE SAID THE ENGINE LIGHT WAS OFF TOO, BE SHE SAID WE KEEP IT TO MAKE SURE ITS FINE,I GOT A RENTAL CAR FROM THEM,THEY TOLD ME IF SOMETHING IS WRONG MAZDA WILL PAY FOR RENTAL, THEY KEPT THE CAR OVERNIGHT,MECHANIC DROVE IT WITH HIM HOME, DID NOT FIND ANYTHING WRONG WITH IT,THEY CONTACT MAZDA AND REMOTELY CHECKED THE SKYACTIV COMPUTER, DID NOT FIND ANYTHING EITHER, THEY UPDATE THE COMPUTER SOFTWARE AS THEY TOLD ME AND THEY WERE GUESSING IT WAS A COMPUTER GLITCH BUT THEY WAVED THE RENTAL CAR FOR DAY AND HALF!! SINCE THEN IT NEVER HAPPENED AGAIN,I EVEN TESTED THE TRACTION FUNCTION IN SLIPPERY ROAD AND WORKS FINE. *TR

I HAVE AN AUTOMATIC SKYACTIV 2012 5DR HATCHBACK. I WAS PULLING OUT ON A BACK ROAD THAT WAS 60MPH AND AS SOON AS I PRESSED THE GAS TO SPEED UP WITH TRAFFIC IT WAS AS IF THE CAR LOST ALL POWER. THE TRACTION CONTROL LIGHT CAME ON AND THE CAR SLOWLY ACCELERATED AS I HAD THE GAS PRESSED TO THE FLOOR. IT VERY SLOWLY SPED UP TO 60MPH AND WOULD NOT GO ANY FASTER. I TRIED PRESSING THE TRACTION CONTROL BUTTON TO TURN IT OFF AND NOTHING HAPPENED. MY WIFE AND I GOT LUNCH AND AFTERWARDS IT WORKED FINE. LAST TIME I WAS AT THE DEALERSHIP THEY TOLD ME THERE WAS A RECALL FOR THE STALLING ISSUE AND THAT THEY HAD FIXED IT. THIS WAS ABOUT A MONTH OR SO BEFORE I EXPERIENCED THE STALL. BEFORE THEN I HAD NOT HAD ANY ISSUES WITH STALLING, JUST WITH PULLING OUT ONTO ROADS. THAT LEADS ME TO MENTION THAT THIS CAR DOES NOT DO WELL WHEN PULLING OUT ONTO ROADS. THE CAR DOES NOT RESPOND WELL. IT LAGS AND THEN WHEN IT REALIZES YOU HAVE YOUR FOOT PRESSED ON THE GAS IT THROWS YOU BACK INTO YOUR SEAT. IT'S AS IF THE CAR IS IN 3RD GEAR WHEN YOU PULL OUT AND THEN THROWS ITSELF INTO 1ST GEAR. THE CAR FEELS VERY UNSAFE. I WISH I WOULDN'T HAVE BOUGHT MAZDA'S 2012 MAZDA3 SINCE, AFTERALL, IT WAS THEIR FIRST ATTEMPT AT THEIR NEW SKYACTIV ENGINE. *TR

AFTER DOWNSHIFTING INTO 2ND OR 3RD GEAR, OR AFTER COASTING IN ONE OF THOSE GEARS WITH THE CLUTCH DISENGAGED, THE ENGINE REVS AND THE CAR "SURGES" FORWARD UPON RE-ENGAGEMENT OF THE CLUTCH. WHEN THIS OCCURS, THE ACCELERATOR PEDAL IS ONLY BEING SLIGHTLY PUSHED, BUT THE CAR ACTS AS IF IT HAS BEEN PUSHED ALMOST TO THE FLOOR. DEPENDING ON THE POSITION OF THE CLUTCH PEDAL WHEN THIS OCCURS, THE ENGINE WILL EITHER REV TO 3000 TO 4000 RPM, OR THE CAR WILL ACCELERATE FORWARD UNTIL EITHER THE BRAKE OR CLUTCH PEDAL IS PRESSED. THIS ISSUE WAS PRESENTED TO THE SERVICE DEPARTMENT AND I TOLD THEM THAT YOU HAVE TO DRIVE IN THOSE CONDITIONS IN ORDER TO RE-CREATE THE PROBLEM. I ALSO TOLD THEM THAT I"VE BEEN DRIVING MANUALS FOR THE LAST 28 YEARS AND DON'T THINK ITS A DRIVER ISSUE, ESPECIALLY SINCE THERE ARE MULTIPLE COMPLAINTS OF THIS SAME ISSUE ON THIS SITE AND OTHER MAZDA FORUMS. THIS NEEDS TO BE TAKEN SERIOUSLY BY MAZDA!!!!!!!!!! *TR

MY 2012 MAZDA 3 SKYACTIV HATCHBACK WITH THE 6 SPEED MANUAL TRANSMISSION IS EXHIBITING UNINTENDED ACCELERATION. THE SYMPTOMS EXHIBITED ARE CONSISTENT WITH MULTIPLE OTHER REPORTS IN THIS SYSTEM. AFTER DOWNSHIFTING INTO 2ND OR 3RD GEAR, OR AFTER COASTING IN ONE OF THOSE GEARS WITH THE CLUTCH DISENGAGED, THE ENGINE REVS AND THE CAR "SURGES" FORWARD UPON RE-ENGAGEMENT OF THE CLUTCH. WHEN THIS OCCURS, THE ACCELERATOR PEDAL IS ONLY BEING SLIGHTLY PUSHED, BUT THE CAR ACTS AS IF IT HAS BEEN PUSHED ALMOST TO THE FLOOR.

THIS ISSUE HAS BEEN CONFIRMED BY MAZDA AFTER MULTIPLE TRIPS TO THE DEALERSHIP FOR SERVICE. UPON THE LAST VISIT, A DATA RECORDER WAS INSTALLED AND RECORDED 7 SPECIFIC UNINTENDED ACCELERATION EVENTS BETWEEN THE DATES OF 11/13/12 AND 11/20/12. ACCORDING TO AN EMAIL I RECEIVED FROM THE DISTRICT SERVICE & PARTS MANAGER FOR DISTRICT 2 OF MAZDA NORTH AMERICA OPERATIONS (MNAO) ON 12/23/12, "THE CONCERN FOUND ON THE DATA RECORDINGS TAKEN FROM YOUR VEHICLE WERE FOUND TO BE A PCM CALIBRATION ISSUE. MAZDA CORPORATION IS WORKING ON A NEW CALIBRATION FOR THE PCM WITH AN UNKNOWN TIME OF COMPLETION." WHEN I REQUESTED THAT MY VEHICLE BE REPLACED WITH ANOTHER OF THE SAME MODEL, THIS WAS THE RESPONSE FROM THE SAME DISTRICT SERVICE & PARTS MANAGER: "SINCE THE CALIBRATION OF THE PCM IS THE SAME ON A 2013 LIKE MODEL WITH A MANUAL TRANSMISSION IT WOULD NOT BE ADVISED TO TRADE YOU INTO THAT VEHICLE AS IT COULD POTENTIALLY EXHIBIT THE SAME CONCERN DEPENDING ON YOUR DRIVING HABITS AND CONDITIONS." I AM CURRENTLY AWAITING A RESPONSE FROM MNAO'S MEDIATION DEPARTMENT REGARDING EITHER REPLACING MY CAR WITH ANOTHER MODEL, OR BUYING BACK THE CAR FROM ME. *TR

APPROXIMATELY TWO OR THREE TIMES A WEEK WHEN DOWNSHIFTING OUT OF A RIGHT OR LEFT HAND CURVE OR TURN, MY 2012 MANUAL TRANSMISSION MAZDA 3 HATCHBACK WILL ACCELERATE ON ITS OWN. THIS IS CHARACTERIZED BY A VARYING INCREASE OF RPMS: 2100 RPMS TO 4500 RPMS, DEPENDING ON THE INCIDENT, AND A SUDDEN LURCHING OR SURGING FORWARD OF THE VEHICLE ITSELF. WHEN APPROACHING CURVES OR TURNS, AT 30 OR 40 MPH, THAT DO NOT HAVE TO BE TAKEN AT A COMPLETE STOP, I ENGAGE THE CLUTCH, APPLY THE BRAKES, AND SLOW THE VEHICLE TO 15-20 MPH. UPON COMING OUT OF THE TURN I SHIFT THE VEHICLE INTO SECOND GEAR. WHEN I SLOWLY RELEASE THE CLUTCH, WITHOUT DEPRESSING THE GAS PEDAL AT ALL, THE CAR'S ENGINE WILL REV, RPMS WILL SURGE TO AS HIGH AS 4000 - 4500, AND THE CAR WILL LURCH FORWARD UNTIL THE CLUTCH IS ONCE AGAIN DEPRESSED. THESE INCIDENTS ARE RANDOM AND ARE NOT DEPENDENT ON SPEED, WEATHER CONDITIONS, OR LOCATION. THESE INCIDENTS HAVE ONLY BEEN DUPLICATED WITH A MINIMAL INCREASE OF RPMS AND NO LURCHING FORWARD WHEN A MECHANIC IS PRESENT. THESE INCIDENTS CAN NOT BE DUPLICATED FOR THE DEALERSHIP AT THEIR FULLEST AND MOST DANGEROUS. *TR

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.
