Go open your hood. Remove the top black plastic shielding that goes between the grille and the radiator. It is secured by some plastic push pin things.

Once you remove that, you should see several weld spots across metal member that those plastic clips shap into. (Called radiator supports? maybe)

Notice any rust? Mine had minor surface rust on the edges of the metal, right next to the radiator.

Sanded it down and painted it with gobs of touch up paint. Probably a problem where road salt is used.

 

Hey man, do you have a photo??
