Front Bumper Cover Warping

I've noticed over the past year, the top of the front bumper cover has been "warping." Instead of making a straight line across, it dips up and down. I know it didn't look like this a year ago when it was brand new, as I have pictures. Has anyone else had this happen to them? I'm afraid that the dealer will say it isn't under warranty because there is a slight scrape on one side of the bumper from some ignorant fool in a Walmart parking lot.

Tsb issued in 2002 for this problem, using better mounting bracing and clips.

Yeah, it wavy across the top on my 2005 as well. I'm just going to live with it. It was the same on all the brand spanking new 2006's on the lot too. Even the $35K+ TB SS's!:shakehead I still cant figure out why anyone would want to shell out that kinda coin for a TB.:screwy:
