THE POWER LIFT TAILGATE DOES NOT OPEN ROUTINELY IN COLD WEATHER. WHEN THE TEMPERATURE DROPS BELOW 40 DEGREES FAHRENHEIT, THE POWER LIFT TAILGATE MAY NOT OPEN OR LOCK PROPERLY UNTIL THE CAR HAS ACHIEVED A STABLE INTERIOR CABIN TEMPERATURE OF 70 DEGREES FAHRENHEIT OR HIGHER. THIS PROBLEM STARTED IN OCTOBER OF 2015, NOT LONG AFTER THE VEHICLE HAD EYESIGHT SYSTEM RECALL SERVICE. THE PROBLEM IS MOST LIKELY TO OCCUR WHEN THE VEHICLE HAS BEEN NOT BEEN RUNNING OR HAS BEEN PARKED FOR SEVERAL HOURS DURING COLD WEATHER. I HAVE CALLED AND HAVE SPOKEN WITH AT LEAST THREE DIFFERENT SUBARU DEALERSHIP SERVICE DEPARTMENTS ABOUT THE PROBLEM AND ALL CLAIM TO BE UNAWARE OF THE PROBLEM, EXCEPT IN OCTOBER (2016) ONE SERVICE MANAGER DID STATE HE BELIEVED A BULLETIN ABOUT THE PROBLEM COULD BE FORTHCOMING.

I WAS FORCED TO REPLACE A 2ND FAILED WHEEL BEARING (LEFT FRONT WHEEL) ON MY 2015 SUBARU OUTBACK 4CYL. LIMITED AFTER 35270 MILES TODAY 29JULY2016. THE FIRST FAILED WHEEL BEARING TO BE REPLACED OCCURRED ON 15JANUARY2016 INVOLVING THE LEFT REAR WHEEL. IN BOTH CASES ABNORMAL NOISE LEVELS WHILE DRIVING FROM THE RESPECTIVE INVOLVED CORNERS OF THE CAR LEAD ME CONTACT TO DEALER TO CONFIRM SUSPICIONS OF POTENTIAL WHEEL BEARING FAILURE IN THE MAKING. BOTH BEARINGS WERE REPLACED UNDER WARRANTEE CONDITIONS AND I AM FOR THE MOST PART SATISFIED WITH THE REPAIRS PERFORMED. HOWEVER, HAVING TWO BEARINGS FAIL THAT NORMALLY COULD BE EXPECTED TO LAST THE LIFE OF THE CAR LEADS ME TO CONCLUDE THAT THERE IS A BATCH OF DEFECTIVE BEARINGS PRODUCED FOR SUBARU THAT MAY ALSO BE FOUND ON OTHER CARS ASSEMBLED APPROXIMATELY THE SAME TIME MY CAR WAS MADE IN DECEMBER 2014 AT SUBARU'S INDIANA ASSEMBLY PLANT. I FEEL THIS IS WORTH A FURTHER INVESTIGATION BY YOUR ORGANIZATION AS MOST CONSUMERS PROBABLY DON'T HAVE A CLUE WHAT A FAILING WHEEL BEARING SOUNDS LIKE AND MORE LIKELY HAVE NO IDEA HOW POTENTIALLY DANGEROUS IT IS TO IGNORE TO WARNING SIGNS TO THEIR DETRIMENT. THE SUBARU DEALER TO CONTACT REGARDING MY SPECIFIC CAR IS METRIC AUTO SALES, INC., 1767 EAST JERICHO TURNPIKE, HUNTINGTON, NY 11743 (631) 499-6777

THEY COULD NOT FIND ANY PROBLEMS. POPPING NOISE AROUND WINDSHIELD CONTINUED FROM TIME TO TIME. TOOK BACK TO DEALER JULY 29, 2015 FOR POPPING NOISE AROUND WINDSHIELD AND POOR RADIO AM RECEPTION. THEY REPLACED THE RADIO BUT AM RADIO RECEPTION STILL NOT GREAT. GOT IN THE OUTBACK ON NOV 17, 2015 AND THERE WAS A 5" CRACK ON THE BOTTOM OF THE WINDSHIELD SLIGHTLY RIGHT OF THE CENTER. A COUPLE OF WEEKS BEFORE THIS I WAS DRIVING AND HEARD A VERY LOUD POPPING NOISE. IT MADE ME JUMP AS I THOUGHT THE WINDSHIELD WAS GOING TO SHATTER BUT NOTHING HAPPENED. I HAD RECEIVED A LETTER FROM SUBARU ABOUT WINDSHIELD CRACKING PROBLEMS SO I CONTACTED THE DEALERSHIP. I TOOK IT IN SO THEY COULD TAKE A PICTURE. AT THAT TIME I ALSO REPORTED PROBLEMS WITH THE DEFROSTER NOT KEEPING THE WINDSHIELD CLEAR ESPECIALLY ON RAINY DAYS AND NIGHTS. THIS PROBLEM WITH THE DEFROSTER HAS OCCURRED SEVERAL TIMES AND IT WAS I THE LOWER PORTION OF THE WINDSHIELD. I THOUGHT THE SUBARU HAD ELECTRICAL L ISSUES BECAUSE OF THE POPPING, POOR AM RADIO RECEPTION AND THE DEFROSTER. NOW THE WINDSHIELD! THIS IS MY FIRST SUBARU AND POSSIBLY LAST IF THE PROBLEMS PERSIST. ALL OF THE INCIDENTS HAPPENED WHILE DRIVING BUT WHEN I DISCOVERED THE CRACK IT WAS PARKED IN THE GARAGE. CRACK US NOW ABOUT 9".

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.
