So my 09 WRX Hatch has just under 6000 miles on it. This morning after driving to work I noticed that the front, passenger side underbody panel was hanging down. (In front of the tire, it is also known as "Plate Air Plap.") So I inspect the car, no damage or scuff marks, etc anywhere, no signs of hitting or running over anything. But the panel is hanging down and only left attached by the plastic fastener. The part where the bolt goes through broke. I push it back up into place above the bumper lip hoping it will stay, but after driving home it was hanging down again.
I plan on checking to see if Subaru will fix this when it's in for the next oil change but I wanted to see if this was a common problem or if anyone had an idea what would cause this? (Especially if they try to claim it's not their responsibility.) I noticed some threads about older models where this piece would mysteriously be missing. Obviously Subaru put it there for a reason and I don't want to have to keep having it replaced.
