My car also got it.

I suspect it's coming from the plastic (like the dashboard).

I cured it some what by when I store it at night in the garage, I leave both windows open a few inches to air it out.

I also bought one of those lemon air fresheners (that little pine tree in wrap), which helps.

It doesn't bother me, I kinda like it, but my wife was also not too fond of it.

I was gonna tell her to dummy up, but then I thought twice about it...lol...
