We are original owners. Starting a month ago, after car sat for a couple of days, battery was 100% discharged. Jump started and drove for 30 minutes, then parked. Two days later, battery 100% discharged. Since original battery, had tested and shown to be weak. Bought and installed new battery. Three days of not being driven later, new battery 100% discharged. Unsafe in that, we could be left stranded if were to occur if car left at airport while on short trip, when camping, etc. This is a widely reported problem that Subaru is being sued for. There appears to be an unknown parasitic charge.

2016 Subaru Outback (purchased new) with severe electrical problems in the form of (frequent) battery discharge/non-start. This has been a reoccurring issue since early 2017 and is still a problem, even after replacement of the previous battery. I've had the replacement battery tested on several occasions after recharging and the result has always been that the battery is in good operating order. Subsequent alternator tests show the alternator is charging within manufacturer specifications. I've performed multiple tests after fully recharging the batter on several occasions, making sure all electrical accessories have remained (off) for extended periods of time, and the battery continues to discharge. The electrical system has been tested with a professional scan tool, on multiple occasions, and has yielded no adverse results. There has never been any vehicle warning indicators activate to indicate a problem. Today (2/25/2022) I had to have my Outback jump started 3 times in route to my home 65 miles away. The car died on the road shortly after the first jump, and again after turning the car off to refuel. I looked online to see if anyone else has had similar issues and found the battery discharge/non-start issue to be widespread....and Subaru seems to have been aware of the issue as early as 2017 according to a TSB Subaru sent to all dealers alerting of a potential electrical problem, but providing no solution. This is a SAFETY ISSUE. If access to an operable car were ever needed in an emergency situation (or) a vehicle lost power while in operation causing an accident resulting in injury or death due to a documented issue Subaru was aware of, but neglected to address, would be tragic. Not only for owners of the affected automobiles, but also any other parties involved. This issue should be immediately investigated & addressed by the NHTSA. thank you.

WENT OUT TO MY CAR THIS MORNING AND NOTICED A LINEAR 6 INCH CRACK IN MY WINDSHIELD-IT EXPANDED FROM NEAR THE WIPER ON THE DRIVER SIDE UPWARD AND WITHIN 2 HOURS ANOTHER CRACK BEGAN ABOUT 5 INCHES LATERAL TO THE EVER EXPANDING FIRST CRACK WHICH IS NOW GREATER THAN 12 INCHES LONG. I CALLED DEVOE SUBARU IN NAPLES FLORIDA AND ASKED ABOUT WINDSHIELD CRACK AND REPAIR-I HAD BOUGHT THE CAR THERE 3 YEARS AGO. I WAS INFORMED THEY DO NOT REPAIR WINDSHIELDS, NEVER DID THEY MENTION THIS WAS A COMMON PROBLEM WITH THE OUTBACK. I CONTACTED SATELLITE WINDSHIELD REPAIR AND GAVE THEM MY INSURANCE INFO AND HOPEFULLY MY PROGRESSIVE INSURANCE WILL COVER THE WINDSHIELD AND THE EYESIGHT CALIBRATION.I THEN GOOGLED THE ISSUE AND FOUND THAT THIS IS A REAL AND FREQUENT ISSUE WITH THE SUBARU.

My 2016 Subaru Outback was built in March of 2016 and the exact same part broken at the exhaust bellows, requiring a $2600 repair. Instead of a issuing a recall Subaru is offering allowances to the repair. The service advisor stated that he has performed many of the same repair outside the production dates listed on recall WUJ-95 - Exhaust Pipe Front (EPF) Bellows Cracking, The production dates need to be extend to include all cars that have defective exhaust bellows and catalytic convertors.

on 2/8/22 I brought my car in for service to an independent repair shop. The service was for the 120k standard service. I had been noticing exhaust smells. They checked the exhaust and found "exhaust leak from center exhaust flange, and exhaust leave from exhaust manifold". They recommended a complete replacement of the exhaust manifold "under Subaru recall". They printed the recall for me. It is WUJ-95. Which recalls 2015-2016 outbacks for this issue. When I contacted the dealer they indicated my vehicle was not under this recall. Subaru Customer care indicated the same as did your website. Subaru said that the recall was initiated by NHTSA and that until NHTSA indicated my vehicle was included in the recall they would not repair it. My vehicle has exactly the same issue as what was found for the recall. The only thing I can assume is that my actual 2016 Subaru outback was manufactured after 9/30/15. I cannot find the exact date of manufacture so cannot tell if that is the issue. However, that actual manufacture date should not be controlling as my 2016 outback has exactly the same issue as the recall. If 2016 outbacks manufactured after 9/30/15 have this same issue they should be included in this recall. I am asking you to review this issue and include my vehicle in the recall.

My car spontaneously burst into flames after I parked it. I had left the car parked and locked in a parking lot next to a rental house and went in to prepare dinner. 20 minutes later my friends arrived at the scene and alerted us to the fact that my car was engulfed in flames. It seems that the fire originated in the engine somehow, but exactly what started it is unclear. There was no accident or collision, and no foul play. Security cameras in the area couldn't see much, but indicate that the vehicle burst into flames pretty much just after I had left it parked and locked.

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.
