THE WINDSHIELD ON MY 2017 SUBARU OUTBACK WITH 28,000 MI. HAS DEVELOPED A CRACK I SEE THAT A LOT OF OWNERS OF OUTBACKS ARE ALSO HAVING CRACKS DEVELOP. NOT SURE IF THERE IS A RECALL ON THE WINDSHIELD. THE CRACK SHOWED UP AS I PULLED THE CAR OUT OF THE GARAGE I WASN'T EVEN DRIVING ON THE ROAD. THE CRACK IS ON THE TOP OF THE WINDSHIELD NEAR THE CENTER.

FAULTY WINDSHIELD, I AM ON MY THIRD WINDSHIELD WHICH HAS JUST CRACKED. THE CRACK ALWAYS BEGINS IN THE SAME PLACE, LOWER PASSENGER SIDE BELOW WINDSHIELD WIPER ASSEMBLY IN DEFROST PORTION OF GLASS. SUBARU HAS REPLACED THE GLASS TWICE AT NO COST AT 27,407 MILES AND 45,099 MILES. NOW AT APPROX. 63,000 MILES IT HAS HAPPENED AGAIN. SUBARU IS "UNAWARE" OF ANY PROBLEM WITH THE WINDSHIELDS IN 2017 OUTBACK MODELS. I AM UNAWARE OF ANY ROCK IMPACT TO THE GLASS. WHILE IN MOTION ON THE HIGHWAY, I HEAR A POP SOUND AND CRACK BEGINS TO FORM AND SPREAD QUICKLY.

POSSIBLE STRUCTURAL DESIGN ISSUE THAT CAUSES THE FRONT WINDSHIELD TO CRACK. OEM WINDSHIELD CRACKED SUDDENLY A YEAR AGO. THE CRACK STARTED AT THE VERY TOP OF THE WINDSHIELD IN THE CENTER. NO APPARENT STONE CHIPS OR OTHER DAMAGE TO ATTRIBUTE THIS TO. ABOUT 8 WEEKS AGO THE REPLACEMENT WINDSHIELD ALSO CRACKED, THIS TIME STARTING UNDER THE DRIVER SIDE HOOD AREA, AT THE VERY BOTTOM OF THE WINDSHIELD. THERE'S NO WAY FOR A ROCK OR OTHER OBJECT TO IMPACT THIS AREA, WHICH, GIVEN THE SUDDEN LARGE CRACKS THAT APPEARED, LEAD ME TO BELIEVE THERE'S A STRUCTURAL STRESS ISSUE COMING TO PLAY ON THE FRONT WINDSHIELD. AS THE FRONT WINDSHIELD IS A STRUCTURAL SAFETY COMPONENT OF THE VEHICLE, I BELIEVE THIS CAUSES A SAFETY ISSUE LONG TERM, NOT TO MENTION A SIZABLE ANNUAL EXPENSE BETWEEN THE WINDSHIELD AND HAVING THE EYESIGHT CAMERAS RECALIBRATED FOR THE NEW GLASS. VEHICLE HAS BEEN ON THE ROAD LESS THAN THREE YEARS. THE 'WHEN DID THIS HAPPEN' DATE SELECTED BASED ON THIS YEARS CRACKING. I DIDN'T TAKE PHOTOS OF LAST YEARS CRACKED WINDSHIELD. CURRENT CRACKED WINDSHIELD STILL IN THE VEHICLE.

REPEATED ISSUES WITH REAR LIFT GATE. INCLUDING NOT OPENING AND STICKING AN ANIMAL IN THE BACK AND NOT SHUTTING COMPLETING HOWEVER GIVING THE INDICATION OF SHUT. TODAY 7-25-19, I WAS DRIVING AT APPROXIMATELY 55 MILES AN HOUR AND THE LIFTGATE NOT SHUT LIGHT ILLUMINATED ON MY DASH DURING THE MORNING COMMUNICATE. THERE WAS NO SAFE PLACE TO PULL OVER UNTIL 10 MINUTES LATER. WHEN I GOT OUT OF THE CAR IT APPEARED TO BE SHUT HOWEVER I HAD TO PUSH ON THE BACK SEVERAL TIMES TO SHUT IT. LUCKILY MY DOG WAS NOT IN THE CAR AT THE TIME, BUT THIS CAN POSE A MAJOR SAFETY ISSUE IF ACTUALLY CAME OPEN. I HAVE CALLED THE LOCAL DEALERSHIP SEVERAL TIMES ABOUT THE ISSUE BUT THEY SAID THEY CANNOT DO ANYTHING IF THEY CANNOT RECREATE IT THEY ONLY RESET THE SENSOR. THIS WAS THE FINAL DRAW FOR ME AND I BELIEVE THE VEHICLE IS UNSAFE. NOTE: PICTURE TAKEN WAS WHEN I WAS AT A STOP LIGHT.

EA21002 · 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.
