Chirping sound going over bumps

[sublime187]

OK, well I have been hearing a chirp sound over the last few weeks when I drive over bumps. Recently it started to get worse, and when pushing down on the left of right side of the trunk I could also hear it. I figured this was suspension related and planned to get it looked at eventually. Well today when I was washing my car and sifting through some products I had in my trunk I found the source of the chirping! It was being caused by the plastic board that covers the spare. Upon pressing down on this board it would sound like there was a little bird in there. So I moved it out of the way, problem solved. Obviously, the senior Infiniti tech should have told me this as part of the pre-buy inspection that I never had done.
