While driving on 55mph road, sunroof suddenly shattered for no apparent reason (no sudden impact from rock or other debris), producing a loud bang, startling driver. Driver momentarily swerved due to being startled by noise from next to head before correcting. No other cars were around on the road at the time and driver is sure no rocks or other objects fell onto sunroof (covered by rooftop cargo box, no trees near street to drop debris). Pieces of glass went upwards and ended up on roof of vehicle.

I was fortunate behind me was enough of grassy area for the car to stop. Yes, I am sure I wasn't pushing gas because eventually after hard pressing the brakes the car stopped. Afterwards I tried pushing both and it was impossible to push both hard as the foot slips off the brake pedal.

The car regularly drains the battery. We are the original owners and have had to purchase 3 car batteries thus far. The car does not provide any warning messages or report any issues. Every time the battery has been drained it happens without explanation, over a dozen times since we’ve owned the car. We’ve always had the batteries inspected, and they’ve been in good contention with life left in them, just drained, needing a recharge. Unfortunately, the car counties to drain the battery, leaving me stranded, including at night away from home. The details for the incident I will be providing below will be for the most recent, this morning.

I have had to have my battery replaced almost every year since I bought this car and there is always a large amount or corrosion no matter how often I clean it. I just read that this has been a known issue of Subaru. I literally just had the dealership in late November tell me at an oil change that I needed to replace my battery. When I informed them that I had just replaced it in February of of this year when I stopped for gas in the middle of the Texas winter storm and my car would not start back up (That battery was only about a year and a half old), they blamed the cold weather and suddenly backpedaled saying it just seemed low so I should keep an eye on it. Yesterday, my car took two tries to start so I am going to have the battery tested again but this means I haven't even gotten a full years worth out of it.

I proudly purchased my 2015 Subaru Outback, new, in April 2015. I currently have less than 18,000 miles on it. During the time I have owned my Outback, I have had to replace the battery 5 times, through no fault of my own. Subaru USA and my Subaru dealership say that I do not drive it enough. B/S. I have done some research online and have found many other Subaru owners who are constantly having battery problems and dead batteries. I understand some have filed a Class Action Suit. The problem appears to be that the battery drains down on a regular basis. Now when I put my car in my garage at night, I turn the headlights off completely, the radio off, the A/C off, and I do not set my parking brake for fear all of the above will drain my battery overnight. I am even afraid to set my car alarm. I have had to call AAA each time the battery has gone COMPLETELY DEAD. They are tired of seeing me. Fortunately for me, each time the battery has died, I was at home and my car in the garage. I am a senior citizen who is afraid my battery will die when I am not close to home. I purchased a Subaru because of its so-called reliability. I am tired of Subaru giving me the runaround and trying to make it look as though I am the problem. I, for the life of me, don't understand how this problem has been swept under the rug by Subaru for so LONG. When I chose the Outback, I had done my homework and went first to the LA Auto Show and the Outback, back then, appeared to be my dream car, which has turned into a nightmare for me. I had a Sienna for 15 years and only replaced the battery twice. PLEASE have your staff seriously look into this Subaru battery drainage problem. I am certainly not alone with this problem. Each time I go to start up my Outback, I have to hold my breath and keep my finger and toes crossed. Subaru USA has given me little or no answer to my problem. My dealership again tells me I have to drive more. The other Subaru owners must not drive enough!!!

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.
