2015 Subaru Legacy: battery drain or dead battery

Filed Apr 9, 2024 · Electrical, Seats · NY

I have had several battery issues that I just believed to be bad luck and would get a new battery under warranty but it has gotten worse lately. It led me to look online and I notice I am not nearly the only one as this complaint has been brought up my numerous people. It is in regards to my 2015 Subaru legacy and how I’m not certain if my car will start if I make a few short trips where I’m “in and out” of the car more than 3 times in a short period of time. There is definitely a parasitic draw issue from the vehicle and it is a safety concern in not knowing if your vehicle is going to start or if you’ll need a jump or worse be stranded. With the amount of complaints on this issue I would have thought there would be a recall. I know there are safety bulletins but nothing that the dealer or Subaru themselves will address. I have also signed up for the battery settlement case but have not heard back in regards to this. I am really wanting to know if there is a solution because I’ve read a lot of reviews where this is happening in newer models also. It needs to be addressed and a resolution should be offered because it is happening to A LOT of Subarus. My other concern was the seats and moonroof. The leather driver seat has torn up and I have put covers over it to look similar but I use a sun screen for the vehicle often and it still tore up the seat. Lastly the moonroof has a defect that the dealer wouldn’t address. There is something wrong with the seal and loud wind gets in somewhere and makes the vehicle shake as though you turned up a base speakers to the loudest setting. The battery issue has been going on for years as well as the moonroof that has a spot that is allowing in air and causes the vehicle to shake. Please help hold subaru accountable for these issues and get back to me with some sort of solution! Thank you for your time.

We have owned two 2015 Subaru Legacy sedans. Both of them have had major battery problems. We've had to have battery tenders (trickle-chargers) installed on both cars, and we're still having battery problems. We've been stuck in various parking lots, unable to start the car, and had to get jumps from others. This is a royal pain, and a potential safety hazard if we are stuck in a remote location. We've been told by our mechanic that this vehicle does not really "turn off" when you shut it down. There are several devices in the car which continue to have a "parasitic draw" on the battery, which it is not capable of sustaining. We've had the battery and charging system checked out multiple times, and everything checks out fine. Replacing the battery will NOT solve the problem. Replacing the battery with a deep-cycle battery will NOT solve the problem. It is an inherent defect in the electrical system of the vehicle. Available for inspection: YES Safety issue: being stranded with a dead battery in a dangerous location Confirmed by an independent service center: YES Inspected by anyone else: NO Warning lamps or messages: NO

Battery continually dies. Driven daily and even after driving same day battery will be dead. Issue occurs more frequently when headlights are set on auto. Seems battery drains when car is off but still pulling a charge. Have been stranded numerous times since purchasing the car 2 years ago. Have had battery checked and told it is fine.

The battery has a parasitic drain, and if left off for more than 8 hours, is completely dead on attempt at restart. This has also killed my passenger side forward window which can no longer go up or down.

Extremely high, abnormal parasitic draining of my battery, in my 2015 Legacy whenever vehicle is not running. This parasitic drain on battery will leave you stranded, if parked for a few days, causing a safety issue, as you can imagine. I always connect and use a battery tender/maintainer with hood up, after every time I use car, when I return car to garage. If I did not have a garage, I would have to connect to this battery charger/maintainer and close the hood to deter exposure to the elements, such as snow, ice, and rain. It is not actual fault of battery, as new perfect battery will drain within a few days with this extremely high parasitic drain. I thought possibly if I blocked the battery remotes from contacting the car, I could reduce this drain. I placed the two remotes into a metal container and then I placed this into a second metal container. This did not resolve the parasitic battery draining issue.

Battery drainage and replacement more often than usual

CAN ( Controller Area Network) is causing a parasitic draining of my battery causing me to have to jump my car regularly and I changed the battery less than a year ago. I know that I'm not the only person that has had this issue, I'm aware of the current class action lawsuit out against Subaru for this current situation. This is a very costly a serious issue that demands attention now. It's very dishonest of Subaru to tell you that nothing's wrong or offer any fix, all while taking our hard earned money. I'm very frustrated because I can't afford to continue messing with this issue nor can I simply go out and buy another vehicle. I have been left stranded both at home and aboard leaving my wife and kids not too mention myself at risk. I have taken the vehicle in and haven't had any remedy. No other failures at the time of this reporting.
