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:

Car battery is draining very frequently which is causing the battery to die. Even for short periods of not using the car, the will fail to start due to the drained battery.

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.

I am the original owner of the vehicle in question. I have been experiencing excessive electrical drain issues throughout the life of my vehicle. I have had to jump it at least 10 times and have replaced the battery 4 times throughout my 7 years of ownership. This is quite excessive and has caused safety issues in the past as you never know when the battery suddenly no longer has enough power to start the vehicle. My fiancé was recently on a ferry and upon landing the vehicle would not start and this caused quite an issue with the ferry operator and resulted in undue stress and anxiety on her. I have also always had an issue with the Adaptive Cruise Control system (EyeSight) in which under what I believe are specific circumstances, the system fails to detect the roadway and road markers in front of the vehicle and abruptly shuts off. This hasn't been a major issue as I am still actively driving the vehicle, but when you are driving 50mph on a highway and suddenly you are decelerating without brake lights indicating so to others around you can cause a sense of alarm. The somewhat specific situations this occurs in is when there is very little to no ambient light on the road. Although my headlights are on, they don't seem to provide enough light for the system to 'see' at all times.

Electrical system drains battery very frequently. I have had alternator checked and is fine. This vehicle drains batteries leaving the car unable to start. The batteries will be dead by the 2 year warranty. I see there is a lawsuit in NJ showing the CAN electrical system does not go to sleep when the car is off.

When the car sits unused for more than several days, it goes completely dead. I have had both my mechanic and the dealer check the entire charging system ( battery, alternator, engine drive belt etc ) to no avail. Everything tests as working within given parameters and my 2015 vehicle w/ 67,000 miles is currently on it's 4th battery ! The dealer has refused to perform the two Technical Service Bulletin(s) issued by Subaru corporate unless l pay for them, as they claim they can find no evidence to show they are needed. As a disabled retiree, I cannot depend on this, my only vehicle, to go to doctors appointments, food shopping and other normal necessary daily activities.

I have experienced two separate occasions where my vehicle accelerated even though my foot was on the brake pedal. Once, I was slowing down on a main street for a stop light behind several other cars. My vehicle began to accelerate and would have rammed the car in front of me if I had not been able to swerve into an empty turn lane. Due to the acceleration, I figured I must have accidentally hit the gas pedal, so I lifted my foot and hit the other pedal--which was the accelerator, and naturally just accelerated the vehicle more. I then put my foot back on the brake and the car came to a stop. The second time, my son was backing into our driveway. He had the brakes on. The car was slowing down. Then it suddenly accelerated backward. My son said his foot was still on the brake pedal when the car accelerated, and he did the same thing I did when I had the issue: he moved his foot to the other pedal, thinking he had made some kind of error, but found that the switch only made the car accelerate more, so he switched back to the brake pedal and the car stopped. In both of these instances, the car was initially braking when the brake pedal was applied, then began to accelerate without a change in foot positioning. The accelerator was not touched in either instances because the vehicle was going slow enough not to need much pressure, and the accelerator is positioned far enough away from the brake as it is impossible to touch both pedals at the same time. The floor mats were properly secured at both times (as they always are) and could not possibly have interfered in any way. Thankfully no one has been hurt or experienced any property damage during either of these episodes, but I am worried that one of these days, something horrible will happen if this problem is not corrected! I will give the date of the most recent occurrence in the information included with this report.

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.

I have a 2015 subaru legacy 2.5i engine. The problem i have is a blown fuse in the main compartment F26 (backup). I have read subaru forum(s) and in earlier years this is same issue that I current have in my car. In the older models this was recalled and the issue was reworked at subaru repair centers at their cost. This issue also said it could cause a over heating and possible cause a fire. Please look into this issue. Kind Regards, Doug Whittemore 57 lexington ave. haverhill, MA 01835

When I was in the garage (about 2 months ago) trying to start my car, it tried to start but did not. Repeated attempts to start the car failed, and it acted like the battery was low. I measured the battery voltage and it was only 5.9 volts. I recharged the battery and took it to an auto parts place to get a new battery. They tested the battery and said it was still good and would not recommend replacing it. The car has been fine since. I realize this is not exactly a safety issue except if it had happened someplace remote and not in my garage where I could work on it it could have been bad. I just found out there is a class action lawsuit against Subaru over their CAN system that sometimes fails (does not go to sleep) and causes the battery to run down faster than it should. It sounds to me like that is what happened to my car. If you are keeping up with complaints about Subaru's CAN system I guess you can add mine to the list (or database). Thanks for your efforts.
