“Battery continually drains. I have had 2 replaced since May. I have contacted Subaru and they said I just have not driven it around enough after battery install. I have had them check for a drain, and they can’t find anything. There are no lights on or any other reason to drain the battery. This coincides with my key becoming stuck in the ignition. Waiting on a part to replace the ignition under warranty.”
