Sorry if there are already threads about this but I tried searching and had no idea what to call this. This is the pointy part of the rear panel on the bottom side of the bumper. The point has become unstuck and you can see the gray adhesive gunk underneath it trying to hold onto it.
Sorry for the dirty bumper.

 

that looks like your rear bumper splash guards is peeling off. you can get that covered under warranty if it never been tampered with.

 

Oh really? Sweet. My ride is an '08 though, won't there be a color match problem if they replace the whole piece?

 

I just went and looked, it's a pretty small piece so it probably won't be noticeable if it's replaced.

 

That's the rear splash guard. They already come factory painted since its an infiniti part. Just get it replaced under warranty

 

Cool, thanks guys.

 

did they replace it?

 

Glue, simple and will do the trick.
