The batteries cannot seem to hold a charge. We have called AAA several times, but the recharging doesn't last, and they say this is a problem with the Outback. In addition, the Subaru dealer has replaced the battery twice. It just failed again. This most recent battery fail stranded my 70 year old husband in another city. I have contacted the dealer again asking for service. There is no warning whatsoever that the battery has drained. This is not a safe situation. The date below is the most recent incident of a drained battery.

Electrical issues affected the battery becoming completely drained, unable to unlock doors, or start the car. This issue has become stressful and worrisome as I have a child and pets. I always have my baby with me and am anxious that I can't unlock the doors. I have taken the car to the manufacturer (dealership) for service three times. They've been able to identify the issue, however, the problem has reoccurred (now the third time). Warning panels would suddenly light up with different messages and the car computer did not retain the information in the last two incidents, however, recorded the information in the latest incident. The first time this happened was in December of 2021 (approximately 50,000 miles).

During a photography trip of May 2021, in a very remote area, the Outback's rear gate was kept opened for my dog for a few hours. When it was time to leave, the battery wouldn't start. Luckily, I had a battery charger. There was nobody present to help in this area and no mobile phone service available. Later in the day, the battery died again, under the same circumstance. We were fortunate to have extra food, water, and blankets if needed to survive the night. I thought maybe the battery was old. I replaced the battery on May 24, 2021 with an Optima 25 battery. This is a better battery than what Subaru installs. This February 2022, we went camping in a remote area of Death Valley with no available services. The fairly new car battery wouldn't start. I used my emergency starter again. This time the rear door and side doors had been opened constantly due to camping activity. It was not possible to disable the lights so as not to drain the battery.

Battery continues to die. We have had our vehicle for a year and had to get to replace our battery 3 times including today! Multiple jumpstarts. Even had it die from leaving out trunk open once. How does that make sense?

Battery continues to drain prematurely. It's been an issue since the very beginning of out ownership in June 2018. We replaced the battery after it would not hold a charge for more than two days. The replacement battery still wouldn't last for more than a day or two. Now in the cold weather it won't even last a day. Two days ago, I went in the grocery store for about 45 minutes and the battery was dead. I can't go anywhere without my portable jump starter.

We have a 2018 Subaru Outback with 87,000. As of yesterday our car is now on its third battery. The original battery lasted about a two years, then we purchased one from Autozone, that battery only lasted 15 months. There is obviously an issue with the electrical system on these cars causing the battery to have a shortened life span. With so many electronics in the car it seems the battery may be to small, it is only a 25 series battery. It could possibly be there are issues with the electrical system cause constant drain. We do know that the car showed no real signs of battery failure before the battery is dead. No slow starting, dim headlights, etc. Both batteries were working well, until all of a sudden they did not. I have read online where this seems to be a real problem with these cars from 2016 to 2019 and possibly the 2020 models.

A week ago, drove 5 miles to get a hamburger. While the car was parked I listened to the radio. When my husband returned with our food 8 minutes later, the car would not start. The battery was dead. This happened again today (11/19/21) when we drove 4 miles and parked. I left the key in the ignition for barely 3 minutes before removing it, but the battery was dead when I tried to start it again a few minutes later. Both instances we used a portable battery charger after having the same problem happen during the summer. Today my husband took the car in to have the battery checked, but it is within normal range (12.2 volts). Aside from the battery problem, the oil lamp also comes on a lot-€¦after getting a complete oil changed which should last us 6k miles or so, the oil warning light comes on after 1,500 or 2k miles, forcing us to add a quart of oil which we always have in the car now.

I experienced premature draining of my car battery. I purchased the car in March 2021. It had approximately 19K miles and was in excellent/showroom condition. This is my first car with GPS and other advanced driving assistance safety features and collision avoidance systems. I'm still trying to understand all of these but some seem to have a mind of their own. I discovered the car's battery dead on the morning of 11/14/21. There was no warning that there might be a low battery problem and the car worked fine the previous day. I researched on-line about why this would suddenly happen and came across the Class-Action Lawsuit filed in April 2020 regarding these problems with Subaru Outback and Ascend models. I will also be contacting the legal team involved with the lawsuit, McKenzie Lake Lawyers, to verify if I need to take any steps prior to having my car fixed. Because Subaru of America and its dealerships deny there is a fundamental problem with premature battery draining, there is no verifiable source on how to repair the car, outside of simply replacing the battery, or how to reset the associated memory features. I have no idea of what electronic and safety features will or will not be operating properly once I replace the battery. I'm also very hesitant to take the car on a long trip over the Thanksgiving Day week.

i own a 2018 Subaru Outback 3.6R Limited. In the last 18 months the battery has died three times while the car is parked. On the second occasion the battery condition was poor and I had to replace it. The third time occurred yesterday. Each time I have had to call for roadside assistance and wait, unable to start/use the car unti the help arrived. I have never had a similar problem with any previous car I have owned.

Battery died for no apparent reason. This left me stranded after dark in Baltimore City. I was able to get a jump start to get home but the car would not start even after the battery was placed on a charger. There are numerous internet news items describing similar stories. I contacted the dealer who refused to assist and therefore replaced the battery myself. There was no warning that this would happen.

Battery intermittently goes dead without warning. When the car is off at times one can hear what sounds like an electric motor running. One time the tail gate was found up and the battery was dead. No one can remember leaving the gate up.

Battery intermittently drains and goes completely dead. At times I have heard what sounds to be an electric motor running at night when the car is off in the garage without the key in the ignition. The dealer has changed the battery but that did not fix the problem.

On multiple occasions, , the battery has gone completely dead after the car was parked for as little as three weeks in a heated garage. Subaru replaced the original battery with one having a larger capacity but even that went dead after not being driven for three weeks. In addition, after the battery is recharged, the front passenger window cannot be rolled down using the driver side window control (the passenger window must be rolled down using the passenger side control before the driver side control will work). Subaru is aware of the battery drain problem because the dealership recommended the purchase of an auxiliary battery to carry in the car in case of a dead battery.
