I’m the original owner, purchased May 2017, and have had to replace the battery five times. Online research indicates that the root cause is phantom draining caused by the DCM apparently searching for a no longer existent 3G signal. Subaru has not addressed the issue directly and has instead issued a technical service bulletin to AAA affiliates to advise their customers to go to dealerships for larger batteries, group 47, with higher cold cranking amps which will also require new battery trays, hold downs and an adjustment to the car’s computer. My dealership in Carlsbad, CA informed me the cost might exceed $650 and would not be covered by Subaru. I strongly believe this is an issue that Subaru must address on their dime.
