I will probably change it out in year three, unless it dies prematurely. I just will not count on it for anything but simply starting the vehicle.I have read several threads in the forum concerning the battery & would direct you to a thread called "Draining the Battery" While quite long in content, it states an opinion that the OEM battery is not suited for handling any accessory drain with the engine not running. In it gives several suggestions for upgrading the battery to one that is better suited to handle these loads. Or you can choose to continue to put up with the OEM letting you down & have the dealer replace it with another that won't prevent you from having the same situation repeated. I would suggest that you bite the bullet, but the better battery & then file a complaint with Subaru of America & ask then to reimburse you. That's what I have done essentially. Good luck!
