   For our 2020 Subaru Outback, we are on our 3rd battery at only 49k miles. The car died again today. Thankfully AAA was able to jump it after a friend tried unsuccessfully. We suspect all of this battery drain, failure and replacement has been due to the known Data Communications Module (DCM) issue on recent Subaru’s. I have an appt w the dealer in Santa Monica tomorrow morning to have it diagnosed.

   We are on our 3rd battery in < 4 years. Subaru is well aware of this issue in their engineering in the parasitic drain from the Starlink module. AAA won’t even replace these batteries anymore because the problem is so prevalent. Meanwhile, I’m about to have to buy a 4th battery less than 4 years after purchasing the car.

   Rear trunk door won’t lock when closed and open up while driving. It’s unsafe as I have to constantly keep an eye in rear view mirror to see if door popped open by itself. Took to service station and they said it’s tied to battery and it is preventing door to close because trunk door takes power to open. I do not understand how trunk door locking close cannot be independent of battery. It is quite unsafe for vehicle occupants and poses danger to other vehicles driving behind.
