2018 Subaru Outback

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.
