This is the 4th battery in my 2016 Outback limited. Three battery replacements in 6 years. See mechanic's report that the charging system tested good but the battery was bad. He found that there is a constant draw on the battery of .726 amps after 20-30 minutes after shut down of the car. There should not be more than .05 amp draw. He said he'd have to test every line of electrical draw on the battery in order to see what is drawing power and not shutting off. That would cost 2 hours of additional labor. I did not want to spend $250 in labor to find out why Subaru malfunctions. I bought a subaru for safety and reliability, not to be isolated with a dead battery. I have needed to jump the dead batteries many times when the car would not start.

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.

I Had to jump start battery on several occasions, leaving myself and my family stranded. I took the car to my dealer on 12/3/2018. Dealer (Glanzmann Subaru) could not identify problem, performed two software updates. I received no information or explanation of the nature of the problem. A month later the problem repeated. I took the car to dealer on 1/16/2019 (mileage 25,941).They tried to tell me that the battery was leaking, but it was not. They replaced the battery and I had to pay the cost for a new battery, $123.97. On 1/27/2021 (mileage 39,172) the new battery failed in a similar manner. The dealership insisted that there were no problems with the charging system. They replaced the battery ( no cost) and performed an ECM update. They were insistent that there were no systemic issues with the electrical system. After the fact, I discovered that this is a universal problem with a number of Subaru vehicles. During a recent visit to my Subaru dealership I inquired as to whether a solution has been determined and will my car be fixed before the new battery also fails. They were very vague and non-informing. I am hesitant to venture far from home with this vehicle since I cannot trust the car or Subaru's support. I can provide dealer service records in support of this issue.

Replacement battery in under 35,000 mile Subaru discharged while sitting in garage for several weeks. There have been zero earlier problems with electrical system other than the original battery dying after about three years. When jump started the charging system seemed to work and the car started after sitting overnight. We are in a very cold northern environment and if the vehicle will not start it could strand us in an unsafe setting. Coming back to a parked car that may have been left at an airport parking lot to find it would not start would be very inconvenient and expensive to remedy.

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.
