Pacifica showing gas cap loose
 

My 2007 Pacifica is showing gas cap loose but I purchased a new one and the same problem exists. Has anyone else had this issue? It seems like both of my vehicles are giving me a hard time with emission testing. I really don't want to take it to dealer and get hammered on a repair bill. Somebody told me that the emission warranty is different from the manufacture warranty. Hopefully this is true.
