I HAD EXPERIENCED A SHUDDER, POP, REVVING RPMS OF THE VEHICLES BEFORE A SUDDEN POWER LOSS AT HIGHWAY SPEED (65MPH). I WAS UNABLE TO ACCELERATE AND HAD LIMITED STEERING TO GET OFF THE HIGHWAY SAFELY. THE VEHICLE HAD STALLED BY THE TIME I WAS ON THE SIDE OF THE ROAD. I WAS THEN UNABLE TO RESTART THE VEHICLE AFTER SEVERAL ATTEMPTS. A TOWING SERVICE WAS CALLED TO BRING IT TO A LOCAL DEALERSHIP. WITHIN AN HOUR TIME PERIOD THE VEHICLE RAPIDLY LOST ELECTRICAL POWER AND HAZARD LIGHTS WERE NO LONGER FUNCTIONAL. THIS UNFORTUNATELY WAS LATE AT NIGHTTIME, MAKING THE VISIBILITY OF THE VEHICLE VERY MINIMAL. THE VEHICLE WAS EVALUATED AT A LOCAL DEALERSHIP AND REPORTED THAT THERE WAS A SOFTWARE PROBLEM WITH THE CHARGING SYSTEMS OF THE CAR. THE SYSTEM WAS UPDATED, BUT THE DEALERSHIP COULD NOT PROVIDE AN EXPLANATION FOR THE REVVING ENGINE, SHUDDERING, POWER LOSS AND STALLING THAT OCCURRED PRIOR TO THE INABILITY TO RESTART THE VEHICLE ON THE SIDE OF THE ROAD.

SUDDEN ACCELERATION: THIS SERIOUS UNSAFE CONDITION RELATES TO MY 2016 OUTBACK LIMITED 2.5L PURCHASED ON 2/29/2016 IN TAMPA FLORIDA. THE EXACT SAME UNSAFE CONDITION HAS HAPPENED TWICE; FIRST IN OCTOBER 2016 AT APPROXIMATELY 8800 MILES, AND SECOND IN DECEMBER 2017 AT APPROXIMATELY 24,000 MILES. DESCRIPTION OF INCIDENT: WHILE SLOWLY PULLING INTO A PARKING SPACE AND GENTLY APPLYING THE BRAKE, THE CAR'S ENGINE RPM ACCELERATED AND I HAD TO BREAK HARD IN ORDER TO STOP THE CAR. I MOVED THE TRANSMISSION TO PARK, BUT THE ENGINE CONTINUED AT HIGH RPM SO I MOVED THE TRANSMISSION TO REVERSE, THEN TO NEUTRAL, THEN I TURNED OFF THE CAR OFF SINCE THE ENGINE WAS STILL AT A HIGH RPM. A NOTICE APPEARED IN MY ODOMETER AREA TO PUT THE CAR IN PARK, WHICH I DID. I THEN RESTARTED IT AND EVERYTHING WAS BACK TO NORMAL AGAIN. NOTE: I DID NOT SIMULTANEOUSLY PUSH THE BREAK AND THE ACCELERATOR TOGETHER WHICH COULD POSSIBLY CAUSE THIS SITUATION. I AM FORTUNATE NOTHING WAS IN FRONT OF ME EITHER TIME. I HOPE NO ONE HAS BEEN INJURED, BUT IT IS LIKELY PROPERTY DAMAGE HAS RESULTED. PLEASE DETERMINE THE CAUSE AND CORRECT THIS POTENTIALLY DEADLY SITUATION. I AM TAKING MY CAR FOR A 24,000 MILE SERVICE ON 1/3/2017 AND WILL DOCUMENT THIS WITH THE DEALER (MASTRO SUBARU) AT THAT TIME. I SUSPECT THIS IS A COMPUTER GLITCH, AND A POTENTIALLY DANGEROUS ONE AT THAT. I ALSO SUSPECT OTHER CAR MANUFACTURERS CAN HAVE THIS SAME ISSUE IF THESE COMPUTERS AND PROGRAMMING ALL COME FROM THE SAME THIRD PARTY.

PULLED OVER CALLED DEALER WHO ATTEMPTED TO WALK ME THROUGH RESET. UNSUCCESSFUL NO AVAILABILITY FOR SERVICE SO SCHEDULED AN APPOINTMENT 3 DAYS LATER. CAR WARNING LIGHTS CLEARED ON THEIR OWN. SHOWED ADVISOR EMAIL FROM AUTO MESS. FROM SUBARU INDICATING WARNING LIGHT WAS AN ISSUE. WAS TOLD CODE WOULD BE CHECKED BUT SUBARU WAS AWARE OF THE ISSUE WHEN SOME CARS WERE OVERHEATED. DEALERSHIP WAS ADVISED TO CLEAR THE CODE AND SEND PEOPLE ON THEIR WAY. NO CODES REGISTERED AT ALL IN THE SYSTEM AND WHEN I LET THEM KNOW THAT CAR WAS ABSOLUTELY NOT OVERHEATED, I WAS TOLD THERE WAS NOTHING THAT COULD BE DONE BECAUSE SUBARU KNOWS THAT WHEN CARS OVERHEAT IT SOMETIMES HAPPENS. NOTHING COULD BE DONE BUT THE GREATER CONCERN IS THAT THEIR PREMISE OF WHEN THE ISSUE IS OCCURRING IS INACCURATE AT LEAST IN OUR CAR'S CASE AND IT DID NOT APPEAR, DUE TO THE REPETITION OF THE COMPANY CONTENTION THAT OVERHEATING WAS THE CAUSE OF THE ISSUE NOR WERE THEY WILLING TO ENTERTAIN ANY OTHER SCENARIO THAN THAT WHICH SUBARU ALREADY DECIDED. SPOKE WITH SUBARU OF AMERICA WHO 7/10/17 CUSTOMER SERVICE WHO STATED NOT AWARE OF ANY ISSUES BUT WOULD LOOK IN TO IT. BY THE END OF DAY 7.13.17.

THE SUBARU EYESIGHT SYSTEM IS DANGEROUS. I'VE HAD TWO INSTANCES WHERE THE VEHICLE ACTIVATED THE FORWARD-COLLISION WARNING AND STARTED TO BREAK FOR REASONS UNKNOWN TO ME. ONCE WAS IN THE MIDDLE OF AN INTERSECTION. FORTUNATELY, THE CARS BEHIND ME WERE NOT TOO CLOSE TO REAR END ME. THIS HAPPENED AROUND 2 P.M. IN THE MIDDLE OF SUMMER WITH THE SUN BEHIND THE VEHICLE. I BROUGHT THE VEHICLE IN FOR RECALL WORK TO THE LOCAL SUBARU DEALERSHIP SEVERAL MONTHS LATER AND ASKED THEM TO PULL ANY RELEVANT DATA FOR THE TWO INCIDENTS. BY THEN, THE SYSTEM CLEARED THOSE TWO EVENTS. THE DEALER SAID I SHOULD PURCHASE A VIDEO CAMERA AND RUN IT IN THE CAR WHILE DRIVING TO CAPTURE ANY FALSE ALARMS IN ORDER TO HELP THEM TROUBLESHOOT IT AS ACCORDING TO THEM THE SYSTEM DOES NOT CAPTURE ANY VIDEO/IMAGE DATA WHEN IT RECORDS AN EVENT. THIS IS ABSOLUTELY OUTRAGEOUS. SUBARU HAS CAMERAS IN THE EYESIGHT SYSTEM AND FLASH MEMORY TO STORE DATA IN - STORING AN IMAGE SNAPSHOT IS NOT OVERLY STORAGE INTENSIVE, AND YET I AM SUPPOSED TO INVEST SEVERAL HUNDRED DOLLARS IN AN INDEPENDENT VIDEO CAMERA TO HELP SUBARU DEBUG THEIR SYSTEM. THE DEALERSHIP SUGGESTED NOT USING EYESIGHT ON SUNNY DAYS WHERE THE CAMERA COULD BE BLINDED BY THE SUN. HELLO - I LIVE IN NEVADA, IT'S SUNNY HERE OVER 300 DAYS PER YEAR. THIS WOULD MAKE THE EYESIGHT SYSTEM PRACTICALLY USELESS AND I'LL LOSE CRUISE CONTROL. HOW AM I SUPPOSED TO KNOW WHEN IT'S TOO SUNNY FOR THE SYSTEM THAT IT WILL MALFUNCTION?

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.
