My vehicle was purchased in September 2014. Approximately the night of March 9, 2017 my daughter apparently turned on a dome light, which remained on the rest of the night. My car had approximately 45k miles on it. The next day I attempted to start the car, nothing happened. The battery was so dead that even connecting to another vehicle for 20 minutes resulted in no change. I purchased a new battery on 3/10/2017. On 7/10/2021 with approximately 100,000 miles I was at an airport for pickup. I turned my car off upon arrival and waited for 30 - 40 minutes with the key in the ignition. I think that resulted in some lights remaining on. When I attempted to start my car to depart the airport it gave an indication of attempting to start but there was not enough power to facilitate the action. I needed to briefly connect my car to another for enough power to start the vehicle, which has run apparently fine since. Now I have to be vigilant to ensure no internal lights are on for more than a few minutes regardless of situation. Recently I read this article, https://www.motorbiscuit.com/dead-batteries-new-subaru-lawsuit-claims-least-five-models-defective-batteries/, which seems to be the situation I am in. It seems that two batteries in a period of 7 years and approximately 102,000 miles seems a bit excessive. A non-technical analysis leads me to think either Subaru is not putting an adequate power supply in at least their Outbacks, maybe other models based on at least the linked article, or something is wrong with the electrical management system resulting in drains on the battery resulting in significantly shorter battery life than found on other vehicles, which results in additional cost to consumers to replace batteries assuming they die at a convenient time and other costs are not incurred.

We have had intermittent issues dating back to late 2019, where returning to the car find that the battery is dead when we went to start it. It usually happens when the vehicle was left for 4 hours or more, although not always. After reading several reports of the same issue, we are going to try a new, larger battery.

I have a parasitic drain on my battery and I have replaced the battery 3 times. It seems my battery is not the issue, but I am constantly stranded on the road and the dealership just replaces the battery. This last replacement I did at a separate shop on 5/10/2021 because my battery needed to be replaced and I thought putting in a different battery would help. Today (7/21/2021), my car will not start again. This shouldn't happen with a new battery and I don't think it's right that Subaru is not doing anything about this issue. It started happening within the first 3 years I owned this vehicle, when it was under warranty. Their solution was to replace the battery and not actually fix the real issue. This is not okay. I drive this car regularly and there is no reason why my battery should die constantly.

Excessive battery drain from open back hatch while parked and engine off. Having my back liftgate open while my engine was off for a 30 minute period drained my battery so that I could not start my vehicle. Had not my friends been there to jump me I would have been without transportation miles from home. No warning light was given by the vehicle. Others with this vehicle have had similar issues and it is an easy issue to find complaints about. A service center has not been contacted yet but I plan on speaking with my dealership soon. This problem blindsided me completely.

It is almost 3 years since the replacement battery and the Subaru service rep said the battery is dying. I fear there is something wrong with the electrical system which damages the batteries over 3 years. I will be replacing the battery again, but what if 3 years later this one dies too? What if, because of the age of the car, the battery dies earlier? When I am on a road trip with family?

In my 2015 Subaru Outback the battery is drained below 50% charge if the vehicle is not driven for a week. It takes daily trips to keep it charged up. The first dead battery was replaced by Subaru after 19 months under warranty. That battery lasted just over two years and it went dead too, while we were away on vacation. I replaced that battery at my expense. My safety is a concern because, if an emergency arose, I don’t know if the vehicle will start. I’ve only involved Subaru when the OEM battery died so soon after buying the car. There is/were/are no warning lights or gauges to inform me of impending battery failure. As a side note, my son owns a Subaru Forester, and because he works at home, there are days he goes without driving it, and between trips his battery is constantly self-draining, too. Very frustrating!

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.
