I WAS DRIVING DOWN A CITY STREET GOING 40 MPH WHEN I HEARD A POP COMING FROM THE WINDSHIELD. WHEN I LOOKED OVER, THERE WAS A CRACK ABOUT MIDWAY UP THE WINDSHIELD. IT RAN FROM THE FAR RIGHT TOWARD THE MIDDLE ABOUT 10 INCHES AND THEN DOWNWARD. IT WAS CURVING DOWNWARD. THERE WAS ONE CAR IN FRONT ABOUT 25 YARDS AWAY GOING ABOUT THE SAME SPEED AS I WAS. I COULD NOT BELIEVE THAT THE CAR IN FRONT OF ME COULD HAVE THROWN A ROCK THAT FAR AND HARD ENOUGH TO BREAK MY WINDSHIELD. I HAVE BEEN HIT MANY TIMES BEFORE ON THE HIGHWAY AND MY WINDOW HAD NEVER BROKEN. ONLY SMALL NICKS THAT I CAN SEE. I GOT TO THE THEATER AND GOT OUT TO LOOK AT THE WINDOW. THE CRACK STARTED FROM THE EDGE OF THE WINDOW. I COULD NOT SEE WHERE ANYTHING HAD HIT THE WINDOW. IT WAS A CLEAN BREAK. I HAD TO TAKE MY OUTBACK TO THE DEALER BECAUSE I'M HAVING PROBLEMS WITH THE WINDOW EXPRESS SWITCH, AND THEY LOOKED AT MY WINDSHIELD. THEY ARE GOING TO REPLACE IT BECAUSE I HAD PURCHASED EXTENDED COVERAGE AND IT WAS COVERED.
I WAS DRIVING MY 2015 SUBARU OUTBACK ON THE HIGHWAY, NORTHBOUND INTERSTATE 280, IN WOODSIDE, CALIFORNIA, ON MAY 27, 2016.

I WAS DRIVING MY 2015 SUBARU OUTBACK ON THE HIGHWAY, NORTHBOUND INTERSTATE 280, IN WOODSIDE, CALIFORNIA, ON MAY 27, 2016. SUDDENLY I SAW A SMALL CRACK ON MY WINDSHIELD THAT GREW TO ABOUT 6 INCHES IN A FEW SECONDS, STARTING FROM THE WIPERS, AT THE BOTTOM AND A BIT TOWARDS THE DRIVER SIDE AND GOING UP THEN CURVING TOWARDS THE RIGHT, IN AN L SHAPE. BY THE NEXT MORNING THE HORIZONTAL PART OF THE CRACK HAD EXPANDED AT LEAST 12 INCHES MORE. I DID NOT HEAR THE NOISE OF IMPACT OF A STONE OR ANY OTHER OBJECT.
THIS IS MY ORIGINAL 2015 OUTBACK. I OWN 2 2015S. MY OTHER ONE ONE HAD A WINDSHIELD ISSUE WHEN I WAS DRIVING AROUND 35 ON A COLD NIGHT. THERE WAS A LARGE POP AND SUDDENLY A CRACK APPEARED ON THE PASSENGER SIDE. OVER THE NEXT DAYS IT GREW INTO A BACKWARDS "J". DEALER SAID IT WAS NOT COVERED, HOWEVER IT WAS DIFFICULT TO EVEN SEE …

THIS IS MY ORIGINAL 2015 OUTBACK. I OWN 2 2015S. MY OTHER ONE ONE HAD A WINDSHIELD ISSUE WHEN I WAS DRIVING AROUND 35 ON A COLD NIGHT. THERE WAS A LARGE POP AND SUDDENLY A CRACK APPEARED ON THE PASSENGER SIDE. OVER THE NEXT DAYS IT GREW INTO A BACKWARDS "J". DEALER SAID IT WAS NOT COVERED, HOWEVER IT WAS DIFFICULT TO EVEN SEE A MARK THAT WOULD INDICATE IT WAS HIT FROM A ROCK, AND NOT DEFECTIVE. WE WENT AHEAD AND FIXED IT, EVEN THOUGH WE THOUGHT IT WAS ODD. THE OTHER MORNING, WE WENT DOWN TO THE GARAGE AND FOUND THAT OUR ORIGINAL 2015 HAD A SIMILAR CRACK ON THE DRIVER'S SIDE, IN A SIMILAR SHAPE AND LENGTH. THE DAY BEFORE, WE DROVE THE CAR TO THE BEACH. NOTHING HIT IT, AND THE CRACK IS SMOOTH, WITH NOTHING FOUND WHERE IT ORIGINATES. SOMETHING IS DEFECTIVE WITH THESE WINDSHIELDS. THERE IS NO WAY 2 WINDSHIELDS ON 2 NEW CARS SHOULD BOTH HAVE TO BE REPLACED. WE OWN OURS CARS A LONG TIME, AND HAVE NEVER HAD A WINDSHIELD EXPERIENCE LIKE THIS, AND IF A ROCK EVER HITS ONE, IT'S A TINY MARK THAT CAN BE HANDLED BY INSURANCE. SOMETHING IS WRONG BUT SUBARU HAS WRITTEN IT SO ANY UPPER WINDSHIELD ISSUES ARE NOT INCLUDED, AND THIS IS NOT RIGHT. WE ARE GOING BUYING OUR SECOND ONE IN FOUR MONTHS, WITH EYESIGHT. THERE IS A DEFECT.

DRIVING ON A ROAD TRAVELING APPROX. 35 MILES AN HOUR ON A COLD NIGHT. HEARD A LOUD POP AROUND THE PASSENGER SIDE UPPER WINDSHIELD. A SMALL CRACK APPEARED. THERE WAS NO BUMP OR ROCK HIT AS THE REST OF THE AREA APPEARED SMOOTH. CRACK SPREAD INTO BACKWARDS "J" SHAPE OVER NEXT FEW DAYS AT LEAST 12 INCHES LONG. DEALERSHIP TOLD ME IT WASN'T COVERED AND THERE WAS A ROCK HIT. BUT THE AREA WAS SMOOTH AND I'VE BEEN DRIVING FOR 30 YEARS AND HAVE NEVER HAD THIS HAPPEN. WE ATE THE COST BECAUSE IT NEEDED TO BE REPAIRED, EVEN THOUGH CONSIDERED IT ODD THAT THIS WOULD HAPPEN. HOWEVER, WE HAPPEN TO OWN ANOTHER 2015 OUTBACK. YESTERDAY, WE WENT INTO THE GARAGE TO START THE CAR AND THERE IS A 12 INCH CRACK - THE SAME SHAPE- ON THE DRIVER'S SIDE IN THE SAME LOCATIONS. NO SIGNS OF A ROCK HIT. WEATHER HAS BEEN VERY WARM, BUT THIS TIME, THE CAR WAS PARKED. SOMETHING IS WRONG. 2 - 2015 OUTBACKS? 2 "J" SHAPED CRACKS? IT'S NO COINCIDENCE AND TOO MANY COMPLAINTS ON LINE FROM PEOPLE WITH SIMILAR SITUATIONS. WINDSHIELD IS FAULTY AND SUBARU WON'T STEP UP AND INCLUDE THE UPPER PART IN ITS RECALLS. IT NEEDS TO. VERY DISSATISFIED CUSTOMER.

WINDSHIELD CRACKED FROM DRIVERS SIDE BOTTOM CORNER ACROSS THE MID LINE ABOVE THE STEERING WHEEL TO PASSENGER SIDE WITHOUT WARNING OR IMPACT FROM AN ROCK OR OBJECT. CRACK BEGUN WHILE DRIVING ON FREEWAY AND WITHIN 45 SECONDS EXTENDED ACROSS THE WINDSHIELD FROM DRIVERS SIDE TO THE MID POINT OF THE WINDSHIELD. CRACK IS IN DRIVERS LINE OF SIGHT, AND A SAFETY HAZARD. TOOK IT TO DEALER, WHO RESPONDED, THAT IT IS A COMMON OCCURRENCE IN THIS MODEL. PULLED OVER AND FOUND NO IMPACT OR ROCK CHIP ANYWHERE ALONG CRACK. WINDSHIELD DEFECTIVE.
WHILE DRIVING THE CAR, A CRACK APPEARED IN MY WINDSHIELD ON THE DRIVER SIDE. IT FORMED AN REVERSE L ABOUT THE MIDDLE OF THE WINDSHIELD. THERE WAS NO IMPACT OR ANYTHING HITTING THE WINDSHIELD. THE CRACK APPEARED BEFORE MY EYES AS I WAS DRIVING UP THE ROAD.

SUBARU 2015 WINDSHIELD CRACK: DRIVING INTO ALBUQUERQUE NM FROM SANTA FE ON HWY25, I SAW A CRACK APPEAR IN MY WINDSHIELD, FROM THE DRIVER'S SIDE. THE NEXT DAY IT HAD GROWN INTO AN L SHAPE.IN 2 MORE DAYS IT HAD GROWN TO AN S SHAPE. I DID NOT SEE ANY CARS CLOSE BY OR ANY ROCK AT THE TIME THE CRACK APPEARED. WHEN I CALLED THE DEALER, I WAS TOLD TO COME IN ON 4-27-16 FOR MY ANNUAL MAINTENANCE, BUT WAS CONCERNED BECAUSE THE CRACK KEPT GROWING. I WENT TO THE ALBUQUERQUE GARCIA DEALER TODAY 4-14-16, I WAS TOLD A TINY PINPOINT SPOT ON THE LEFT SIDE OF THE WINDSHIELD INDICATED A ROCK HAD CAUSED THE CRACK TO START. BUT I HAVE DRIVEN CARS FOR 40 YEARS AND NEVER SEEN ANYTHING THIS DRAMATIC. I NOW HAVE READ ONLINE ABOUT DOZENS OF COMPLAINTS LIKE MINE AND MOST VICTIMS BELIEVE THE FLEXING OF THE CAR BODY MAY HAVE CAUSED THIS CRACK. THE FRAGILITY OF THIS WINDSHIELD MAKES THIS CAR EXTREMELY DANGEROUS. I BELIEVE THIS CAR SHOULD HAVE A SAFETY RECALL.
6-8 INCH CRACK IN WINDSHIELD, NO ROCK IMPACT OR PREVIOUS DAMAGE. WINDSHIELD HAS TO BE REPLACED AND EYESIGHT SYSTEM RE-CALIBRATED. CRACK OCCURRED DRIVING STRAIGHT ON A 4 LANE HIGHWAY, NO TRUCKS IN THE AREA, NOT CLOSE TO OTHER CARS.

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.
