There is a constant squeaking noise that comes from the back of the car while driving... Its driving me nuts... Anyone else have this? It sounds like plastic rubbing etc. Driving me crazy...

Also, there is something on the inside of my tunk that rattles when the door opens and shuts... Also driving me nuts

 

So go sit in the back of the truck and have someelse drive it. Only you are going to be able to find a squeak. For what it is worth, it is not necessarily normal.
