2009 Murano, 280,000km
So today, right when I'm getting off Deerfoot to get back in Airdrie, I all of the sudden notice a strong smell of gas (or maybe exhaust?) inside my car. I thought nothing of it as I thought it was coming from outside and the smell seemed to almost disappear to nothing by the time I pull into my driveway.
Then about a half hour later I get back in, strong smell again but nothing in the outside air so I know it's my car...I drive off, it goes away. Park at the clinic and come back out an hour an half later, same thing, smells like gas. Drive back home nothing while it's running, get home, no smell, just went out, still smell gas...
I have owned over 25 different used cars in my life, have never come across this and can't seem to find anything similar online...it's mostly people smelling gas while driving...any help?
Could it be an exhaust leak of some kind, as I have had the P0420 code come on twice over the past 2 weeks, but it hasn't come on since...I cleared it as I have this code on previous Nissans before and it is commonly known issue on Nissans, emmission sensor related and doesn't affect the drive.
Another thing I came across on a Nissan forum was that maybe a gas line runs through the trunk just behind the inner panels and maybe that is leaking? I have not noticed a huge drop in my gas gauge though...
