What owners wrote
“My car is a 2018 with only 28100 miles on it. I have now had to replace the battery three times. Subaru tells me I need to drive it every two days in order to keep it from discharging the battery. This is unacceptable. Clearly there is a parasitic drain. My issue is very common, and affects many late model subarus. I have already been stranded several times by this issue.”

“new battery that is only 14 months since installation (at subaru dealer) and 5,000 miles on the car is flat. I did not use my car for about 1 1/2 weeks in the garage and it is totally flat. This is not normal and my friend with an outback has similar problems so I think my issue is not unique.”

“We have discovered that our 2019 Forester has a parasitic battery drain of almost 1 amp when the car is off and the hatchback is open. This resulted in full battery drain several times until we did several tests to determine the root cause of the problem (Subaru was of no help). This led to replacement of the OEM battery at about 52,000 miles.”

“Bought vehicle June 2021. Battery failed multiple times. Sometimes it will start with a jump, but on 12/2/21 it was completely dead and required tow to Michael's Subaru dealer in Bellevue, WA. Battery was replaced twice within 6 week period.”

Should you keep driving it?
This page can't tell you that. 0 of 43 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
