THE CAR AFTER 6 MONTHS HAS BEEN MAKING AN INTERMITTENT RATTLE NOISE THAT I BROUGHT INTO SUBARU TO INVESTIGATE. I SHARE THE VIDEO BUT THEY STATED THEY NEED TO RECREATE THE NOISE TO KNOW WHAT WAS WRONG. AFTER SEVERAL MONTHS, THEY FINALLY HEARD THE NOISE AND WITHOUT TESTING STATED THE EVAPORATOR PUMP NEEDED TO BE REPLACED. AFTER REPLACING THE PUMP THE ISSUE WAS STILL THERE. I THEN PUSHED THE ISSUE FURTHER AND SUBARU AMERICA ONLY RECOMMENDED THAT I BRING THE CAR TO ANOTHER DEALERSHIP. I DID THIS WHERE THEY PLANED TO DRIVE THE CAR TO AND FROM THEIR TOP MECHANICS HOME HOOKED UP TO THE DIAGNOSTIC SUBARU COMPUTER. WHEN WE PICKED THE CAR UP WITH NO RESOLVE, THEY ONLY DROVE THE CAR FOR 1 MILE WHICH MEANS IT NEVER WHEN BETWEEN MILFORD, CT TO MONROE, CT. AT THIS POINT MY FAMILY IS POISED TO LOSE THOUSANDS OF DOLLARS ON A BRAND NEW CAR THAT DOES NOT MEET THE LEMON LAW IN MY STATE AND HAS NO RESOLVE FOR A NOISE THAT WAKES UP MY 14 MONTH SON WHO IS A SOUND SLEEPER. THE NOISE IS EXTREMELY LOUD THAT PEOPLE CAN HEAR THE NOISE WHEN OCCURRING WHEN INSIDE THEIR HOMES AS I PULL UP. THE LAST DEALERSHIP ADVISOR TOLD ME SUBARU KNEW OF A SIMILAR CASE WHERE THE COMPUTER WAS DEFECTED AND HAD TO EXCHANGE THE MATTER BUT IN MY CASE THEY DID NOT RECOMMEND THIS AND WHEN I ASKED WHY TO THE SERVICE MANAGER, HE DENIED WHAT THE ADVISORS TOLD ME FROM THE NOTES. I FEEL SUBARU HAD DECEIVED ME AND IS TRYING TO COVER SOMETHING UP AS I DO NOT FEEL CONFIDED THAT THE EMISSIONS OR OTHER MECHANICS SYSTEMS ARE WORKING PROPERLY DESPITE SUBARU STATING EVERYTHING IS NORMAL.

THIS ISSUE IS A SAFETY ENHANCEMENT REQUEST AFFECTING TOP OF THE LINE SUBARU OUTBACK 2016 LIMITED/PREMIUM MODELS EQUIPPED WITH KEYLESS IGNITION SYSTEMS. THIS ISSUE IS SIMILAR TO THAT REPORTED IN NHTSA ID NUMBER:10881286. ISSUE: IT IS POSSIBLE FOR A DRIVER TO INADVERTENTLY TURN OFF THE ENGINE (WE ARE ONLY HUMAN) USING THE START/STOP BUTTON WHEN THE VEHICLE IS IN DRIVE, PARK OR NEUTRAL. IF VEHICLE IS ON A SLOPE, THE VEHICLE WILL ROLL FORWARDS OR BACKWARDS ON IT'S OWN. THIS PRESENTS A SERIOUS RISK OF GRAVE BODILY HARM TO PEOPLE IN THE PATH OF THE UNATTENDED MOVING VEHICLE. THIS ALREADY HAPPENED WITH MY VEHICLE, LUCKILY IT HAPPENED INSIDE MY GARAGE ON A VERY SLIGHT SLOPE AND MY CLOSED GARAGE DOOR STOPPED THE VEHICLE. IF MY CHILDREN HAD BEEN BEHIND THE VEHICLE, REMOVING THEIR SCHOOL BAGS, THEY WOULD HAVE BEEN PINNED TO THE GARAGE DOOR BY A 3500 LB VEHICLE. UNACCEPTABLE. I REPAIRED THE SLIGHT DAMAGE BODY WORK ON THE VEHICLE AT THE DEALER BUT THAT IS IRRELEVANT COMPARED TO THE SAFETY RISK PRESENTED BY THIS "WORKS AS DESIGNED" BEHAVIOR OF THE CAR. POSSIBLE WORKAROUND: 1. SUBARU NEEDS TO CHANGE THIS BEHAVIOR AND ELIMINATE THE RISK BY AUTOMATICALLY ENGAGING THE ELECTRIC "PARK BRAKE" THAT IS ALREADY INSTALLED IN THIS MODEL VEHICLE, WHEN THE ENGINE IS TURNED OFF. 2. DISABLE ENGINE STOP UNTIL TRANSMISSION IS SET TO PARK. THE CURRENT AUDIBLE WARNING IS INSUFFICIENT. MY 15 YEAR OLD VEHICLE DID NOT ALLOW THE KEY TO BE REMOVED FROM THE IGNITION SLOT UNTIL PARK LEVER WAS ENGAGED TO PREVENT THIS EXACT PROBLEM. *TR

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?

I EXITED THE EXPRESSWAY. I WAS APPROACHING A RED LIGHT. THIS WAS WHERE I USUALLY MAKE A RIGHT TO GO HOME. OBVIOUSLY I WAS TRYING TO SLOW DOWN THE CAR, AND I STEPPED ON THE BRAKE. AND THE CAR DID NOT SLOW DOWN. I CONTINUED PUMPING THE BRAKES BUT THE BRAKES WOULD NOT WORK. MY WIFE WAS IN THE PASSENGER SEAT, AND MY MOTHER-IN-LAW WAS RIDING IN THE BACK SEAT. AS THE BRAKES FAILED, I CONTINUED ATTEMPTING TO SLOW THE CAR. ULTIMATELY, WE WERE INVOLVED IN A TWO-CAR COLLISION IN WHICH THE PASSENGER SIDE WHEEL-WELL OF MY CAR WAS CRUSHED. MY WIFE, MY MOTHER-IN LAW, AND I SUFFERED SEVERE INJURIES. MY WIFE SUFFERED FRACTURED RIBS, A FRACTURED STERNUM, A FRACTURED PELVIS, AND HER ANKLE WAS CRUSHED. MY MOTHER-IN LAW SUFFERED FRACTURED RIBS AND A CONCUSSION. I SUFFERED FRACTURED RIBS, AND THE TRAUMA HAS LED TO A FLAIR UP OF MY PREEXISTING MEDICAL CONDITIONS. FOLLOWING THE ACCIDENT, WE WERE RUSHED BY EMS TO THE HOSPITAL WHERE WE RECEIVED TREATMENT FOR OUR INJURIES. WHILE MY MOTHER-IN LAW AND I WERE RELEASED FROM THE HOSPITAL NEXT DAY, MY WIFE CONTINUES TO RECEIVE TREATMENT AT THE HOSPITAL. SHE HAD ON HER ANKLE EXTENSIVE RECONSTRUCTIVE SURGERY THAT REQUIRED THREE METAL PLATES TO HOLD HER BONES TOGETHER WHILE THEY HEAL. SHE WILL SOON BEGIN REHABILITATION, LEARNING TO WALK AGAIN. MY WIFE'S RECOVERY IS EXPECTED TO TAKE MANY MONTHS. SHORTLY AFTER BUYING THE CAR, IT WAS RECALLED DUE TO ISSUES WITH THE CAR'S STEERING COLUMN. RECENTLY, MANY MORE OF THE SAME CAR HAVE BEEN RECALLED DUE TO ISSUES WITH THE CAR'S BRAKE CALIPERS. I BELIEVE MY CAR MAY HAVE EXPERIENCED THESE BRAKE ISSUES TOO. I WOULD APPRECIATE AN INVESTIGATION INTO THE BRAKES OF 2016 SUBARU OUTBACKS. THANK YOU. *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.
