Same thing happened to me. A small plastic piece popped out of the front bumper. Luckily I just popped it back in with no issues.
Also, just for information purposes, my rear bumper got hit in a parking lot. Small crack near the rear exhaust with a 1 foot white scratch. I started a thread "rear bumper replacement...cause hit and run" if you want to check out pictures. Went to Subaru here in Toronto, which has a body shop and they told me that they can replace it or repair it. I guess they have a special plastic welder. Repairing it = $642 + tax. Replacing it is $150 more. I am leaning towards replacing it due to the small cost to replace the ENTIRE rear bumper cover vs just repairing a small area. Would you guys agree?
