WHILE TRAVELING THROUGH MICHIGAN'S UPPER PENINSULA AND NORTHERN WISCONSIN DURING SNOW FALL WITH A FULLY PACKED CAR ON THE HIGHWAY I EXPERIENCED THE REAR END "GHOST WALKING" OR "STEERING" OR "PULLING" TO THE LEFT AND TO THE RIGHT. I HAD TO DRIVE 40MPH WHILE TWO-WHEELED DRIVE CAMRYS, CIVICS, VANS, ETC. PASSED US BY. GROWING UP IN NORTHERN MICHIGAN, I'M NO STRANGER TO WINTER CONDITIONS AND ALL WHEEL DRIVE VEHICLES. I DON'T THINK ALL-WHEELED DRIVE VEHICLES MAKE ME INVINCIBLE, BUT THEY DO MAKE DRIVING IN WINTERY CONDITIONS BETTER. AFTER OUR TRIP, I TOOK THE CAR INTO THE SUBARU DEALER AND THEY SAID AT 37K MILES, THE SUSPENSION LOOKED GREAT, ALIGNMENT LOOKED GREAT, AND THAT THEY WOULD RECOMMEND NEW TIRES (TIRES ARE AT 4/32 AND HAVE EVEN WEAR AND TEAR). I ASKED TO SPEAK DIRECTLY TO THE TECH WORKING ON MY CAR AND HE SAID THAT THERE WAS NOTHING WRONG WITH THE VEHICLE AND THAT ALTHOUGH THEY WERE RECOMMENDING NEW TIRES, THE CURRENT TIRE CONDITION WOULD NOT CAUSE WHAT I WAS DESCRIBING. MY WIFE AND I THEN RESEARCHED AND CAME ACROSS SEVERAL ONLINE FORUMS WITH OTHER DRIVER'S EXPERIENCING THE SIMILAR ISSUES, BUT WITH PRIOR YEAR MODELS. I CALLED SUBARU'S MAIN CUSTOMER SERVICE LINE TO SEE IF THEY COULD HELP AND THEY SAID THAT THEY WOULD MAKE NOTE OF MY COMPLAINT, BUT THAT IF THE SUBARU DEALER TECH SAID THE VEHICLE WAS FINE OTHER THAN SUGGESTING NEW TIRES, I SHOULD GET NEW TIRES AND THE VEHICLE WOULD BE FINE. SUBARU ALSO SAID THERE WERE NO "CAMPAIGNS" OPEN WITH RESPECT TO THIS PROBLEM AND THAT THEY WERE SORRY I "FELT LIKE I HAD THIS EXPERIENCE" AND THERE WAS NOTHING THEY COULD DO. HERE'S A LINK TO A FORUM, WHERE THE PEOPLE SEEM TO KNOW WHAT IS GOING ON: HTTPS://WWW.SUBARUOUTBACK.ORG/THREADS/2005-2009-GHOSTWALKING-ABNORMAL-WINTER-HANDLING-FIXES.30747/PAGE-2. WE PLAN TO BUY NEW TIRES, BUT ARE WILLING TO OFFER OUR CAR UP FOR TEST DRIVING TO SEE WHAT IS GOING ON.

WHILE DRIVING AT HIGHWAY SPEEDS ON CLEAR DRY ROADWAYS, THE STEERING FEELS AS IF I HAVE A BRIEF LOSS OF CONTROL. I LIKEN IT TO HITTING A PATCH OF ICE AND HAVING A SLIGHT LOSS OF STEERING CONTROL. I'VE NOTICED IT TWICE WHILE ENTERING A CURVE AND DECELERATING FROM 55 MPH TO 45 MPH (THE REDUCED SPEED LIMIT OF THE CURVE). THIS ISSUE HAPPENS ONLY INTERMITTENTLY AND IS ONLY NOTICEABLE AT HIGHWAY SPEEDS. WE HAD THE SUBARU DEALER LOOK AT IT AND THEY SAID NOTHING WAS WRONG.
THE KEY GETS STUCK IN THE IGNITION AND WILL NOT RELEASE. HAVE TO LEAVE THE KEY IN IGNITION ALL THE TIME.

NOTE THAT THE FAILURE OF THESE SYSTEMS DOES NOT CAUSE A CHECK ENGINE CONDITION AND NO ERROR CODES ARE LOGGED. THE DEALER INDICATED THAT THE FIRST 4/5 FAILURES LEFT NO CODES. THE NEXT FAILURE WAS DELIVERED TO DEALER WHILE RUNNING IN A FAILED STATE. DEALER REPORTED NO CODES FOUND. SINCE THE DEALER DID NOT REPORT THIS TO SUBARU I WILL BE REPORTING THIS PROBLEM TO SUBARU.

NOT ABLE TO TAKE KEY OUT OF THE IGNITION, KEY IS BEING STUCK 50% OF THE TIME. SECOND ISSUE IS THE ENGINE IS MAKING BIRD CHIRPING NOISE, IT COMES AND GOES BUT IT GETS LOUDE!! TOOK IT TO DEALER A YEAR AGO BY THE TIME I GOT THERE THE NOISE STOPPED SO THEY COULD NOT FIGURE OUT THE ISSUE, TOOK IN THE SECOND TIME ABOUT 8 MONTHS AGO THE SERVICE TECH HEARD IT AND BOOKED ME FOR AN APPOINTMENT. BY THE TIME MECHANIC GOT TO IT NEXT DAY IT STOPPED. THIS WAS ALL UNDER WARRANTY AND NOW I AM OUT OF WARRANTY AND HAVE NO SUPPORT FROM A LOCAL DEALER FROM WHERE I BOUGHT THE CAR. I DID SOME RESEARCH ON THIS ISSUES AND THERE IS A HUGE PROBLEM WITH THIS AND SUBARU IS NOT DOING ANYTHING ABOUT IT.

WHEN LANE KEEP ASSIST IS ON AT NIGHT (USES EYESIGHT TO KEEP YOU IN YOUR LANE) THE CAR STEERING WHEEL HAS ON TWO SEPARATE OCCASIONS SUDDENLY JERKED TO THE RIGHT. THE FIRST TIME THERE HAD BEEN SOME ROAD REPAIRS WITH SOME PARTS OF THE ROAD HAVING NEW ASPHALT AT SOME NOT, AND THE ROAD WAS STILL WET FROM A PREVIOUS RAINSTORM. THE MOST RECENT TIME THE ROAD WAS DRY AND THIS HAPPENED WHEN THE CAR REACHED AND EXIT WHERE THE PAINTED STRIPE ON THE RIGHT SIDE OPENED AT THE ANGLE FOR CARS TO DEPART THE INTERSTATE TO ALLOW FOR THE EXIT. THE FIRST TIME THERE WERE TWO IMMEDIATE JERKS TO THE RIGHT. THE LAST TIME A SINGLE JERK. EACH TIME I HAD TO FORCIBLY JERK BACK THE CAR BACK TO THE MIDDLE OF THE LANE I WAS IN, OR WE WOULD HAVE LEFT THE ROAD AT 65 MPH. I HAVE STOPPED USING LANE KEEP ASSIST - THIS WAS VERY DANGEROUS. THE FIRST TIME I ASKED THE SALESMAN AT SUBARU OF CHAMPAIGN ABOUT THIS, AND HE DIDN'T KNOW ABOUT IT. AFTER THE SECOND OCCURRENCE I DECIDED IT WAS A DANGEROUS DEFECT AND HAD TO REPORT IT. THANK YOU.

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.
