Hello to all. New to the forum, and new to Subaru !! I bought the wife a 2013 Legacy and she loves the car. It's kind of chilly tonight (28 now, maybe 22 for a low). I went outside to get some firewood from the front porch, and I hear a buzzing sound. Upon further investigation, it is coming from the car. More specifically, the left rear of the car, right above the muffler as best I can tell. I opened the trunk, it's empty. It's as if a small motor is running somewhere in the rear of the car. Any ideas on what this is ? Thanks in advance for your help !
