2017 Subaru Outback: battery drain or dead battery

Filed Apr 7, 2026 · Electrical · OR

I think recall work was not done, but says it was done (or is not open). Does it say when and where recall work was done? This car has a parasitic battery drain, 3 batteries in 3 years, required 2 jump starts, 1 call to AAA. There is a recall for such an issue, but I do not believe it was fixed and done. It showed NO open recalls, and just last week I had brake work for a recall done.

Battery drain kept on happening. The nth time after buying 2 batteries and getting battery recharge 2x, Subaru sent me a letter of notice of possible problems with car keeps on finding radio or gps signal thus drains the battery. Brought car to Subaru then they changed the signal unit and gave me a new battery as well.

DCM Parasitic Drain Lawsuit for 2016-2019 Subaru Battery consistently drains to where my vehicle will not start. Dealer has replaced the battery twice (2018 & 2019) I replace the battery in 2022 and will need to so it again soon. Vehicle will not start after sitting for more that 7 days. I've been stranded at night on dark roads.

The back lift gate is closed according to the dash display, but the computer detects that the lift gate is NOT closed resulting in a battery drain. The indication that I get is when I start driving I get a beeping noise. I reset the hatch by pressing the hatch button manually. It opens and closes but when you restart the car you get a hesitation as if the battery is dead. This is the 2nd time this has happened to me in the last month and the 3rd time in the past 5 months this year. April 19th I had to jump my car because the battery was dead. I took it to a mechanic and they checked the battery and they advised the battery is fine. It happened again on May 11th, where I put something in the trunk, I closed the trunk it was closed no indication that it was not. The car drove fine. I started the car and again the battery hesitation, when I started driving I received the same beeping, I had to get out the car and manually open the hatch to reset it. The computer needs to be adjusted to detect when the lift gate is actually closed. Having the lift gate not closed but no indication for the drive is a safety problem.

Vehicle has a chronic battery drain issue. I have replaced batteries repeatedly. If the vehicle sits undriven for a few days the vehicle will not start due to dead battery. It is unsafe to have a vehicle you cannot rely on to start. There is no warning when this occurs. This is happening every where for the 5th generation Subaru Outbacks, Foresters and was subject to a class action lawsuit. Subaru's response is to install a new battery, charging the customer a 'discounted' price without fixing the cause of the battery drain.

Battery - Subaru battery failed. Purchased a new aftermarket battery that failed after 5 months. No warning. Completely dead. Taking to dealership for "diagnostic" test on March 20, 2022. This is a known issue with a class action settlement. I was told I did not qualify for reimbursement of any kind. Subaru does not have any "fix" for this problem and numerous owners of these vehicles are having battery drain problems throughout the US and Canada.

My 2017 Subaru Outback has a parasitic battery drain. The battery dies after one day of non-use. It has to be jump started. The battery is less than two years old and is the second battery since we purchased this car in 2019. Took it to a auto repair service to be checked and the technician found a parasitic draw that continually cycles between .05 mil amps to .14 mil amps. This may be the CAN system not going into sleep mode and draining the battery. This is a potentially hazardous situation and can leave me stranded in remote or dangerous locations. Subaru is well aware of this problem and yet has not addressed this problem.
