I have a 22 refresh LTZ with the 3.0 and now have about 10K miles on it. I have never had any smell such as you mentioned. Not sure what it could be. Mine can idle in the garage and it is practically odorless and as for in the cab never anything at all. Perhaps they used some type of undercoat or sealant on the underside. I would ask. I would think it would soon be gone.
