I was finally able to take a picture to show you what it looks like. If you look at the front of the engine you can see where the fan shroud has bounced back and hit the plastic trim piece. Also, notice the clips -- they work their way back up every time I push them back down. I think I'm going to buy a new set of clips and see if it makes a difference.

Here's the picture:
