ORIGINAL WINDSHIELD CRACKED BY ROCK (I THINK) HIT AT TOP NEAR EDGE AND CRACK INSTANTLY RAN DOWN AND ACROSS THE WINDSHIELD. TOOK TO DEALER FOR REPLACEMENT, TOOK ALL DAY BECAUSE THE FIRST WINDSHIELD THEY INSTALLED BROKE, SO THEY HAD TO PUT IN A SECOND. A WEEK LATER HEARD A LOUD POP, LIKE A ROCK HAD HIT THE WINDSHIELD AND WINDOW CRACKED FROM JUST ABOVE THE WIPER ON THE PASSENGER SIDE UP AND TO THE MIDDLE OF THE WINDSHIELD. IF IT WAS A ROCK IT COULDN'T HAVE CAME DIRECTLY IN BUT WOULD HAVE HAD BEEN LOBBED AS A STRAIGHT IN SHOT WOULD HAVE CLIPPED THE WIPER AND THE WIPER HAS NO DAMAGE. THERE IS A VERY SMALL DING IN THE WINDSHIELD, CERTAINLY NOT SIGNIFICANT ENOUGH TO CAUSE A CRACK THAT WOULD INSTANTLY RUN ACROSS THE WINDSHIELD. DEALER WILL NOT WARRANTY A 1000 WINDSHIELD THAT I HAD FOR A WEEK. I DON'T THINK THE INTEGRITY OF THE WINDSHIELD IS SOUND IF A SMALL ROCK DINGS THE WINDSHIELD AND CAUSES IT TO CRACK. IF SOMETHING OF SIZE WERE TO HIT IT I THINK IT WOULD LIKEY BREAK THROUGH AND COULD SERIOUSLY INJURE SOMEONE. THIS IS A HUGE SAFETY ISSUE, THE GLASS IS DEFECTIVE. WINDSHIELDS ARE BUILT TO WITHSTAND SERIOUS IMPACT WITHOUT CRACKING. SOME NEEDS TO LOOK INTO THIS. I'VE SEEN MANY PEOPLE REPORTING THIS ONLINE AND SOMEONE IS GOING TO GET HURT. SUBARU NEEDS TO RECALL ALL THE VEHICLES AND REPLACE WITH SAFE GLASS AND THEY NEED TO REIMBURSE ALL THOSE LIKE ME THAT HAVE INCURRED RIDICULOUS EXPENSE BECAUSE OF THIS DEFECT.

ON MARCH 24, 2019, MY HUSBAND AND I WERE DRIVING NORTH ON INTERSTATE 5 IN SOUTHERN OREGON, TRAVELING FROM OUR WINTER HOME IN NEVADA TO OUR SUMMER HOME IN ALASKA. SUDDENLY, WE HEARD A LOUD EXPLOSION ON THE ROOF OF OUR CAR. THE SUNROOF GLASS HAD SPONTANEOUSLY EXPLODED AND SHATTERED!! THERE WERE NO ROCKS OR DEBRIS ON THE ROAD. SINCE WE WERE TRAVELING, I WAS ABLE TO GET THE SUNROOF REPAIRED AT WALKERS RENTON SUBARU IN RENTON, WASHINGTON. EVEN THOUGH THE VEHICLE WAS STILL UNDER THE FULL BUMPER TO BUMPER 36,000 MILE WARRANTY (IT HAD 27,000 MILES ON IT), I WAS REQUIRED TO PAY THE $500 REPAIR BILL. THE SERVICE ADVISOR TOLD ME THAT THE BREAKAGE HAD TO HAVE BEEN DUE TO A ROCK, AND WAS NOT COVERED UNDER WARRANTY. I AM CONVINCED THAT THERE WAS NO ROCK OR ANYTHING ELSE THAT CAUSED THE SHATTERING OF THE SUNROOF GLASS. THERE ARE SCATTERED REPORTS OF SUNROOFS SPONTANEOUSLY EXPLODING, AND I AM CONVINCED THAT THAT IS WHAT HAPPENED TO ME.

AFTER PARKING, I FREQUENTLY CAN'T GET THE KEY OUT OF MY 2017 SUBARU OUTBACK, MAKING IT IMPOSSIBLE TO LEAVE THE VEHICLE. IT CAN TAKE DOZENS OF RESTARTS, SWITCHING FROM DRIVE TO REVERSE TO PARK AND MOVING THE WHEEL TO BE ABLE TO RELEASE THE KEY. ALSO, FREQUENTLY, WHEN THE CAR IS PARKED, I AM ABLE TO INSERT THE KEY BUT CANNOT TURN IT TO START THE CAR. THIS STARTED WHEN THE CAR WAS UNDER WARRANTY BUT DID NOT BECOME AN OBVIOUS/FREQUENT PROBLEM UNTIL JUST AFTER THE WARRANTY ENDED. I HAVE READ ON LINE THAT THIS WAS A DESIGN FLAW AND THE PART HAS BEEN REDESIGNED BUT THEY DID NOT ISSUE A RECALL AND ARE NOW CHARGING ME FOR THE NEW PART. I BELIEVE THIS IS A SAFETY ISSUE (BEING STUCK OUTSIDE IN MASSACHUSETTS IN WINTER WITHOUT BEING ABLE TO LEAVE OR SOMETIMES START MY CAR) THAT THEY SHOULD BE ADDRESSING. THIS HAPPENS MANY TIMES EACH WEEK, AND IS COMPLETELY UNPREDICTABLE.
I AM RANDOMLY UNABLE TO REMOVE THE KEY FROM THE IGNITION AFTER PLACING THE VEHICLE IN PARK. IT HAS TAKEN ME UP TO TEN MINUTES TO GET THE KEY OUT. SOMETIMES JUST WIGGLING THE SHIFTER IN THE PARK POSITION IS ENOUGH TO GET THE KEY TO RELEASE. OTHER TIMES I HAVE TO REPEATEDLY START AND STOP THE ENGINE, AND MOVE THE GEARSHIFT LEVE…

I AM RANDOMLY UNABLE TO REMOVE THE KEY FROM THE IGNITION AFTER PLACING THE VEHICLE IN PARK. IT HAS TAKEN ME UP TO TEN MINUTES TO GET THE KEY OUT. SOMETIMES JUST WIGGLING THE SHIFTER IN THE PARK POSITION IS ENOUGH TO GET THE KEY TO RELEASE. OTHER TIMES I HAVE TO REPEATEDLY START AND STOP THE ENGINE, AND MOVE THE GEARSHIFT LEVER FROM PARK TO DRIVE AND BACK TO PARK TO GET IT TO RELEASE. THE KEY WILL TURN ALL THE WAY TO THE OFF POSITION IN THE IGNITION BUT SOMETHING IS PREVENTING IT FROM BEING PULLED OUT OF THE IGNITION SWITCH. SEARCHING GOOGLE FOR THIS PROBLEM REVEALS THAT MANY OTHERS ARE HAVING THIS PROBLEM, AND THE DEALER'S SOLUTION IS TO REPLACE THE ENTIRE SHIFT ASSEMBLY AT YOUR EXPENSE IF YOU ARE OUT OF WARRANTY. THAT IS WHAT THEY TOLD ME, EVEN THOUGH THEY APPARENTLY HAVE A TSB ON THE PROBLEM.

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.
