Persistent battery drain. Car was jumped a week ago because it wouldn't start at all. It has been sluggish to start (turns over a couple times before catching) since and had a major error with the rear hatch today despite starting up. Power rear hatch will alarm as open but then cannot be opened with key fob, button in car, or button on hatch. The rear alarm will ring consistently until car has been running for 10 min/reached 60 mph but restarts again at stop lights. It is currently scheduled to be looked at in 4 days, if it is able to be safely driven to the dealership.

Over the last month or two the battery has been going dead over night, and sometimes almost immediately after parking it. I understand that there is a class action law suit pending on this issue, and I understand Subaru will replace the cheap small battery with another cheap small battery which is only kicking the can down the road since as far as I know not fixing the underlying electrical issue in the car. I tend to drive some roads that have long stretches of mountainous terrain even though a Federal Highway. No phone service is often and issue and should this problem strike me on one of these trips I may have some problems getting going again.
Battery dies every couple months despite nothing being on without vehicle on.
Battery discharges too quickly, leaving me with a car that won't start. I've already replaced the battery once - to the tune of over $300 because I needed roadside assistance - and I'm looking at having to do it again. I've been stranded multiple times and have had to find someone to jump start my car. I just ordered a $200 c…

Battery discharges too quickly, leaving me with a car that won't start. I've already replaced the battery once - to the tune of over $300 because I needed roadside assistance - and I'm looking at having to do it again. I've been stranded multiple times and have had to find someone to jump start my car. I just ordered a $200 car jumper so I don't get stranded again.
The car set overnight (was fine) next AM no electrical. Everything locked except driver's door and passenger door. No battery charge at all. Everything DEAD.
Replaced 2 new batteries in 6 months. Batteries went totally dead. Batteries wer replaced by independent shop. Dealer changed battery to a subaru oem battery, checked system, said everything ok. Read about complaints about subaru batteries going dead months apart. Want to find out if there is a defect in subarus.
I bought this Outback new back in June of 2018. I just purchased the 3rd battery for it today 8/11/22. I’ve noticed that the past 2 batteries have been corroded and barely last 1.5-2 years. It sounds like this is an issue with many other owners as well where the battery either doesn’t fully charge or continues to deplete when th…

I bought this Outback new back in June of 2018. I just purchased the 3rd battery for it today 8/11/22. I’ve noticed that the past 2 batteries have been corroded and barely last 1.5-2 years. It sounds like this is an issue with many other owners as well where the battery either doesn’t fully charge or continues to deplete when the car is off and parked. The battery gets so low and is so corroded that it can’t get jumped by remote starters and requires a jump from a started car. The shop I took it to to replace the battery said they couldn’t get a read from their battery checker because the terminals had so much acid on them.
