2016 Subaru Legacy

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.

While traveling approximately 70 mph, my 2016 Subaru Legacy experienced a sudden drivetrain failure. The vehicle made a loud bang, immediately lost acceleration/power, and approximately five seconds later the front drivetrain locked, causing the tires to skid and leaving a long skid mark. The engine remained running. After stopping, the vehicle would not move forward and felt as if it was stuck in Park, but it could roll backward. This occurred without warning and created a dangerous highway situation

The factory touchscreen infotainment system is experiencing severe screen delamination (internal adhesive failure). This defect causes uncontrollable 'ghost touching,' where the screen registers phantom inputs. The system cycles through radio stations, changes audio sources, and changes navigation without driver input, causing an extreme, sudden driver distraction. Furthermore, the system frequently freezes and crashes, which completely disables the backup camera display. This prevents a clear view behind the vehicle and creates a severe safety hazard for pedestrians. The dealer confirmed the issue. Contacted Subaru of America and they are unwilling to assist at all with fixing the issue, leaving the customer to pay full price to replace the screen. Does not seem like a fair business practice.

Battery dies all the time. Parasitic drain from the Starlink program in the car. There is/was a lawsuit. It involves some DCW fuse or something. Ive had to prematurely replace my battery. It also seems to be affecting the radio. It switches stations randomly.

Battery continuously dies, likely due to a parasitic drain, and it is extremely hard-taking up to 15 to 20 minutes to open the car door using the the wierd key you slide out of the key fob. As a woman, it is very dangerous when my battery dies and I am in a dark parking lot and I can't even get inside the car and lock the door for safety. Been happening for years lastest time was today 02/17/2026. For some reason, the class action suit said I was not a class member for the same problem.

THIS IS THE SECOND SUCH EXPERIENCE WITH THIS CAR! On Friday, September 12, 2025 at 3:32 p.m., I was driving slowly in a parking lot preparing to park. As I started to turn the car into the parking space, my car surged forward without my pressing on the gas pedal. I pressed on the brake, and the car came to a stop.

Sometimes when starting from a stop or slowing down to make a turn the engine revs up like I was pushing the gas pedal. When this happens ( 4 times in the last 6 months) luckily I was covering the break to slow down or going very slow from a stop. Each time I was turning left or right. I was able to push the shifter into neural. After applying the breaks the engine slows down
