Sorry to hear. I had the same issue. I have added security (extended warranty). Dealership replaced it FOC.

 

Check out this video. See comments about dealer fix. We have a 2019 outback. Im out of town a lot and my wife informed me she had replaced the battery 4 times!

 

Call subaru customer service. The dealer should fix at no charge

 

So what’s the $10 fix?

 

The forum search or google search is your friend.

Since you asked nicely forum link is below. You only need to two low profile fuse taps and fuses as shown in post #15 which are less than $10.

As per the other threads and posts on this forum about the issue, removing a fuse will solve the battery drain problem of the DCM.

Please note that if you do this the hands free microphone and front speakers may no longer work.

There is also a simple $10 fix for the problem that only powers the DCM module when the ignition is turned on. This may be a better option and allows the front speakers and microphone to work.

If the battery has gone flat multiple times you will probably have to replace it due to the battery now having reduced power storage.
