I have heard multiple car owners stating the same issue yet when I contact Subaru they refuse to acknowledge this is an issue. I have increased the CCA on the battery, make sure my key is nowhere to assist in draining. When I connect my jump box (which I now carry fully charged in my car) it reads my battery isn't dead at all.

This problem started in early 2019 then again in Nov 2019. I will continue to add the additional month basically if i don't drive the car every day, I know the following day I have to get a jump. I've gotten new batteries every time this has happened. Told the dealership and even if under warranty they simply replace the battery and the issue continues. At this point, I will be selling the car to avoid further issues.

Known issue. The car draws more amps than the alternator can recharge the battery, so eventually you will have a dead battery. Took it in a couple times at Subaru of Gwinnett in GA. 1st visit, they said nothing was wrong. 2nd visit, battery was dead when they tried to start it, so they replaced battery with same battery and supposedly did a software update. Still having depleted battery, so I put a charger on it once a month. It will charge for 10 hours or longer each time. Have been doing this every month for 3 1/2 years.

Call Subaru @ Gwinnett now, their advise is to purchase a larger CCA aftermarket battery. Yes, you read that correctly. We at Subaru are not going to fix a known issue with our Outback’s electrical system...sorry. It’s your problem to solve. Installing a larger CCA battery only buys you more time between putting a charger on. Doesn’t solve the problem.

Been happy with my 2016 Outback Limited / 2.5L 4-Cylinder DOHC. Then, over the past three 3 weeks I've required a jump start because of battery drain. The first time I blamed it on leaving the accessories on when parking for 3 minutes after turning car off. The second time I kept my foot on the brake petal a while after parking. The third time was yesterday. Colder weather has hit Minnesota. The factory battery is only 356 CCA, not enough for a Minnesota winter. After the third time I replaced the battery with 550 CCA. I suspect a new battery will help with adding dependability again, but suspect the problem of battery drain will continue because of the quick electrical draw.

It happened several times since middle of 2018. A typical case is that after I drive about 1 hour from home to my company with audio on, when I try to start the car before going home, it is difficult to start it, just like the battery is gone. Another case is that after driving 30 minutes, I waited for about 10 minutes in Costco gas station with car in idle, after refilled gas, the car almost cannot be started (hesitating start). Just have Walmart auto service check the issue, thought it must be a dead battery issue. But it came out that the battery is good! Now, I even dare not to listen any radio when I am driving. My Outback is even less than three years old! Will bring the car to dealership for further analysis.

Accidentally left the accessory switch on after stopping the engine. Tried to start about 20 minutes later, dead battery. Subaru roadside assistance was there in a short while. A jump started it right up. This could have been bad. Fortunately we had not locked the car. With the battery dead we could have not entered the car to a close windows (threatening rain) or gotten to the roadside assistance info in the glove box. Lesson learned put the info into the cellphone. Checked the owner’s manual. It says after an hour the accessory switch will turn itself off to save battery.

Took it to the dealership and this was the eye opener! They told us the battery will never last that hour. Customers are having this issue after only FIVE minutes of accessory power. The battery checked out as being fine. Service guy said they put in light duty batteries in order to decrease weight and help with gas mileage.

My confidence is this car is really shaken now. Thought the first incidence was just a fluke.
