I bought my altima new in October, although it was an 08 model. It only had 70 miles. It doesn't really have the normal new car smell. No mace or chemicals have been spilled. I've ventilated it a *lot*, but it doesn't help with the odor that emanates after stopping.
I've also speculated that the odor comes from a material that encases the battery that heats up.
How many miles does your car have?
So your dealership is agreeing that there is an odor?
I've yet to contact my dealer. That's next. I'm also going to call Nissan.

I just created it. Didn't want me real address to get on some junk list
