I was driving to work when the engine low oil light came on. I checked the oil immediately and it appeared to be down about a quart. I contacted the dealership and took it in the next day. They confirmed the oil was down about a quart and started an engine oil study. I am to take the car back to the dealership in 1200 to have the oil level checked. This appears to be a known problem with the 2011 and above Subarus. This all happened a month or so after I had already taken the car to the dealership after having a burnt oil smell from outside of the car. Nothing was found.
