Started hearing a rubbing noise under the Crosstrek Thursday morning on the way to work. I got out of the car twice to look for anything that I might have run over but didn't see anything hanging around the wheel wells or under the car. I called my dealer to have a look-see and they scheduled me for Monday morning. There was no apparent problem with the XV except for the light rubbing/scraping noise that sometimes would stop but always came back. It even disappeared when I had two other folks in the car for a short trip. Well today I got out my flashlight, and thanks to the ground clearance, got under the car and found a 12 inch long pine tree branch wedged behind the right rear tire. It even looked like a brake line; same color and diameter. After carefully pulling it out the noise has completely disappeared.....time to cancel the visit to the dealer service area!!!
